Description

[Technical field]

[0001] The present disclosure is generally directed to an absorbent article comprising a laminate exhibiting a crisp graphic perception. The present disclosure is also directed to an absorbent article comprising a laminate comprising a nonwoven web having a visually identifiable pattern in combination with a color graphic for an improved overall crisp graphic perception. [Background technology]

[0002] Absorbent articles comprising nonwoven webs are used to contain and absorb bodily exudates (i.e. urine, feces, and menstruation) of infants, children, and adults. Absorbent articles can include, but are not limited to, diapers, pants, adult incontinence products, feminine care products, and absorbent pads. Various components of these absorbent articles include one or more nonwoven webs. Some exemplary components that include nonwoven webs are, for example, outer cover nonwoven materials, belt portions, landing zones, and topsheets. In some cases, one or more graphics are printed on the backsheet film of the absorbent article. It is sometimes desirable that these graphics are visible through the topsheet or through the outer cover nonwoven material. If the outer cover nonwoven material or topsheet is a planar non-variable intensive web, the graphics will be somewhat patchy, uniformly suppressed, and / or uniformly masked from the consumer's view looking through the topsheet or outer cover nonwoven material. Therefore, the outer cover nonwoven materials, the topsheet, and the backsheet graphics should be improved. Summary of the Invention [Means for solving the problem]

[0003] The present disclosure provides, in part, an absorbent article including a laminate that exhibits a sharp graphic perception. The present disclosure also provides, in part, an absorbent article including a laminate including a nonwoven web having a visually distinct pattern of three-dimensional features in combination with a backsheet color graphic for an improved overall sharp graphic perception. The laminate may include one or more nonwoven webs that overlap the backsheet. The nonwoven web of the present disclosure allows one or more graphics on the backsheet to be more visually distinct to the consumer when viewed through the nonwoven web. This improves the consumer experience. The nonwoven web may be, for example, a topsheet, a portion of a belt, a landing zone, or an outer cover nonwoven material. The nonwoven web may include a variable average intensive web. This allows certain portions of one or more graphics on the backsheet to have higher or lower visual clarity through the nonwoven web, resulting in a more vivid consumer experience with the graphic. As an example, the nonwoven web may include one or more visually distinct patterns of three-dimensional features on the first surface or the second surface. At least some of the three-dimensional features may each comprise a first region and a second region. The first region may have a first value of average intensiveness. The second region may have a second value of average intensiveness. The first and second values ​​may be different. A portion of the visually distinct pattern of the three-dimensional features may overlap one or more graphics printed on the backsheet to allow each region of the graphic to be more visually distinct in either the first or second region. The one or more visually distinct graphics on the backsheet film significantly enhance the perception of the one or more visually distinct patterns of the nonwoven web when the nonwoven web is overlapped with the one or more visually distinct graphics.

[0004] The present disclosure provides, in part, an absorbent article comprising a liquid permeable topsheet, a liquid impermeable backsheet, an absorbent core positioned at least partially intermediate the topsheet and the liquid impermeable backsheet, and an outer cover nonwoven material. The outer cover nonwoven material comprises a first garment facing surface, a second backsheet facing surface, and a visually distinguishable pattern of three-dimensional features on the first surface or the second surface. At least some of the three-dimensional features each comprise a first region and a second region. The first region has a first value of average intensiveness. The second region has a second value of average intensiveness. The first value and the second value are different. The garment facing surface of the backsheet includes one or more visually distinct graphics. A portion of the visually distinguishable pattern of three-dimensional features overlaps a portion of the one or more visually distinct graphics. The portion of the one or more visually distinct graphics exhibits a chroma value greater than 8 according to the Backsheet Graphic Color Test. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0006] In order to provide a general understanding of the principles of the structure, function, manufacture, and use of the absorbent article with vivid graphic perception disclosed herein, various non-limiting embodiments of the present disclosure are described below. One or more examples of these non-limiting embodiments are shown in the accompanying drawings. Those skilled in the art will understand that the absorbent article with vivid graphic perception described herein and illustrated in the accompanying drawings is a non-limiting exemplary embodiment, and the scope of the various non-limiting embodiments of the present disclosure is defined only by the claims. Features shown or described with respect to one non-limiting embodiment can be combined with features of other non-limiting embodiments. Such modifications and variations are intended to be within the scope of the present disclosure.

[0007] Before considering the nonwoven web having a visually distinct pattern and the laminate having a visually distinct graphic perception, absorbent articles and their components and characteristics are considered as one potential application of the nonwoven web. It will be understood that the nonwoven web having a visually distinct pattern and the laminate having a visually distinct graphic perception also have other uses in other products, such as, for example, the medical field and / or the cleaning and / or dusting field.

[0008] Overview of absorbent articles An exemplary absorbent article 10 according to the present disclosure shown in the form of a taped diaper is shown in Figures 1-3. Figure 1 is a plan view of the exemplary absorbent article 10 laid flat (i.e., without elastic contraction) with the garment-facing surface 2 facing the viewer. Figure 2 is a plan view of the exemplary absorbent article 10 of Figure 1 laid flat with the wearer-facing surface 4 facing the viewer. Figure 3 is a front perspective view of the absorbent article 10 of Figures 1 and 2 in a fastened configuration. The absorbent article 10 of Figures 1-3 is shown for illustrative purposes only, as the present disclosure may be used to make a wide variety of diapers, such as, for example, adult incontinence products, pants, or other absorbent articles such as sanitary napkins and absorbent pads.

[0009] The absorbent article 10 may include a front waist region 12, a crotch region 14, and a rear waist region 16. The crotch region 14 may extend intermediate the front waist region 12 and the rear waist region 16. The front waist region 12, the crotch region 14, and the rear waist region 16 may each be one-third of the length of the absorbent article 10. The absorbent article 10 may include a front edge 18, a rear edge 20 opposite the front edge 18, and transversely opposed side edges 22 and 24 extending longitudinally and defined by a chassis 52.

[0010] The absorbent article 10 may include a liquid permeable topsheet 26, a liquid impermeable backsheet 28, and an absorbent core 30 positioned at least partially intermediate the topsheet 26 and the backsheet 28. The absorbent article 10 may also include one or more barrier leg cuffs 32, with or without elastics 33, one or more leg elastics 34, one or more elastic waistbands 36, and / or one or more acquisition materials 38. The acquisition material(s) 38 may be disposed intermediate the topsheet 26 and the absorbent core 30. An outer cover nonwoven material 40, such as a nonwoven web, may cover the garment-facing surface of the backsheet 28. The absorbent article 10 may include back ears 42 in the rear waist region 16. The back ears 42 may include fasteners 46 and may extend from the rear waist region 16 of the absorbent article 10 and be attached (using fasteners 46) to a landing zone area or landing zone material 44 in the garment-facing portion of the front waist region 12 of the absorbent article 10. The absorbent article 10 may also have front ears 47 in the front waist region 12. Instead of two front ears 47, the absorbent article 10 may have an integral front belt that may also function as a landing zone. The absorbent article 10 may have a central lateral (or transverse) axis 48 and a central longitudinal axis 50. The central lateral axis 48 extends perpendicular to the central longitudinal axis 50.

[0011] In another example, the absorbent article may be in the form of a pant with permanent or refastenable side seams. Suitable refastenable seams are disclosed in U.S. Patent Application Publication No. 2014 / 0005020 and U.S. Patent No. 9,421,137. Referring to FIGS. 4-8, an exemplary absorbent article 10 in the form of a pant is illustrated. FIG. 4 is a front perspective view of the absorbent article 10. FIG. 5 is a rear perspective view of the absorbent article 10. FIG. 6 is a plan view of the absorbent article 10 laid flat with the garment-facing surface facing the viewer. Elements in FIGS. 4-8 having the same reference numbers as those discussed above in connection with FIGS. 1-3 may be the same elements (e.g., absorbent core 30). FIG. 7 is an exemplary cross-sectional view of the absorbent article taken about line 7-7 of FIG. 6. FIG. 8 is an exemplary cross-sectional view of the absorbent article taken about line 8-8 of FIG. 6. 7 and 8 show exemplary configurations of the front belt 54 and the back belt 56. The absorbent article 10 may have a front waist region 12, a crotch region 14, and a back waist region 16. Each of the regions 12, 14, and 16 may be one-third of the length of the absorbent article 10. The absorbent article 10 may have a chassis 52 (sometimes referred to as a central chassis or central panel) including a topsheet 26, a backsheet 28, an absorbent core 30 disposed at least partially intermediate the topsheet 26 and the backsheet 28, and an optional acquisition material 38, similar to that described above with respect to FIGS. 1-3. The absorbent article 10 may include a front belt 54 in the front waist region 12 and a back belt 56 in the back waist region 16. The chassis 52 can be joined to the wearer-facing surfaces 4 of the front and back belts 54 and 56, or to the garment-facing surfaces 2 of the belts 54, 56. The side edges 23 and 25 of the front belt 54 can be joined to the side edges 27 and 29 of the back belt 56, respectively, to form two side seams 58. The side seams 58 can be any suitable seam known to those skilled in the art, such as, for example, a butt seam or an overlap seam. Once the side seams 58 are permanently formed or refastenably closed, the pant-form absorbent article 10 has two leg openings 60 and a waist opening perimeter 62.The side seams 58 may be permanently joined, for example using an adhesive or bond, or may be refastenably closed, for example using hook and loop fasteners.

[0012] belt 7 and 8, the front belt 54 and the back belt 56 may include a front inner belt layer 66 and a back inner belt layer 67 and a front outer belt layer 64 and a back outer belt layer 65 having an elastomeric material (e.g., strands 68 or a film (which may be perforated)) at least partially disposed therebetween. The elastic elements 68 or film may be relaxed (including cut) to reduce elastic strain on the absorbent core 30, or alternatively may run continuously across the absorbent core 30. The elastic elements 68 may have uniform or variable spacing between them in any part of the belt. The elastic elements 68 may also be prestrained to the same or different amounts. The front belt 54 and / or the back belt 56 may have one or more elastic element-free zones 70 where the chassis 52 overlaps the belts 54, 56. In other examples, at least some of the elastic elements 68 may extend continuously across the chassis 52.

[0013] The front inner belt layer 66 and the back inner belt layer 67 and the front outer belt layer 64 and the back outer belt layer 65 can be joined using adhesives, heat bonds, pressure bonds, or thermoplastic bonds. Various suitable belt layer configurations can be found in U.S. Patent Application Publication No. 2013 / 0211363.

[0014] The front belt edge 55 and the rear belt edge 57 may extend longitudinally beyond the front chassis edge 19 and the rear chassis edge 21 (as shown in FIG. 6), or they may be coterminous. The front and rear belt side edges 23, 25, 27, and 29 may extend laterally beyond the chassis side edges 22 and 24. The front belt 54 and the rear belt 56 may be continuous (i.e., have at least one layer that is continuous) from belt side edge to belt side edge (e.g., the transverse distances from 23 to 25 and 27 to 29). Alternatively, the front belt 54 and the rear belt 56 may be discontinuous from belt side edge to belt side edge (e.g., the transverse distances from 23 to 25 and 27 to 29) such that they are distinct.

[0015] As disclosed in U.S. Patent No. 7,901,393, the longitudinal length (along the central longitudinal axis 50) of the rear belt 56 may be longer than the longitudinal length of the front belt 54, which can be particularly useful for increased buttock coverage when the rear belt 56 has a greater longitudinal length compared to the front belt 54 adjacent or immediately adjacent the side seam 58.

[0016] The front outer belt layer 64 and the rear outer belt layer 65 may be separated from each other so that each layer is distinct, or alternatively, these layers may be continuous so that the layers run continuously from the front belt edge 55 to the rear belt edge 57. This can also be true for the front inner belt layer 66 and the rear inner belt layer 67, i.e., they may be separate or continuous in the longitudinal direction. Furthermore, the front inner belt layer 66 and the rear inner belt layer 67 may be separate in the longitudinal direction, while the front outer belt layer 64 and the rear outer belt layer 65 may be continuous in the longitudinal direction, so that a gap is formed between them (the gap between the front outer belt layer 64 and the rear outer belt layer 65 and the gap between the front inner belt layer 66 and the rear inner belt layer 67 are shown in FIG. 7 and the gap between the front inner belt layer 66 and the rear inner belt layer 67 are shown in FIG. 8).

[0017] The front belt 54 and the back belt 56 may include slits, holes, and / or perforations that provide increased breathability, flexibility, and a garment-like texture. The underwear-like appearance can be enhanced by substantially aligning the waist and leg edges at the side seams 58 (see Figures 4 and 5).

[0018] The front belt 54 and the back belt 56 may include graphics (see, for example, 78 in FIG. 1). The graphics may extend substantially around the entire circumference of the absorbent article 10 and may be located across the side seams 58 and / or across the proximal front belt seams 15 and back belt seams 17, or alternatively adjacent seams 58, 15, and 17 in the manner described in U.S. Patent No. 9,498,389 to provide a more underwear-like article. The graphics may also be discontinuous.

[0019] Alternatively, instead of attaching belts 54 and 56 to chassis 52 to form a pant, separate side panels may be attached to the side edges of chassis 22 and 24.

[0020] A nonwoven web having a visually discernible pattern may be used as part of a belt positioned over one or more visually distinct graphics on a backsheet film to achieve the benefits of the present disclosure.

[0021] Top sheet The topsheet 26 is that portion of the absorbent article 10 that directly contacts the wearer's skin. The topsheet 26 may be joined to portions of the backsheet 28, the absorbent core 30, the barrier leg cuffs 32, and / or any other layers, as known to those skilled in the art. The topsheet 26 may be conformable, soft feeling, and non-irritating to the wearer's skin. Additionally, at least a portion of the topsheet, or the entire topsheet, may be liquid permeable, allowing liquid body exudates to readily penetrate through its thickness. Suitable topsheets may be manufactured from a wide range of materials, such as, for example, porous foams, reticulated foams, perforated plastic films, woven materials, nonwoven webs, woven or nonwoven webs of natural fibers (e.g., wood or cotton fibers), synthetic fibers or filaments (e.g., polyester fibers, or polypropylene fibers, or bicomponent PE / PP fibers, or mixtures thereof), or combinations of natural and synthetic fibers. The topsheet may have one or more layers. The topsheet may be perforated (element 31 in FIG. 2), may have any suitable three-dimensional features, and / or may have multiple embossments (e.g., bond patterns). The topsheet may be perforated by strongly bonding the materials and then rupturing the strong bonds via ring rolling as disclosed in U.S. Pat. No. 5,628,097 (Benson et al., issued May 13, 1997) and U.S. Patent Application Publication No. 2016 / 0136014 (Arora et al.). Any portion of the topsheet may be coated with a skin care composition, an antimicrobial agent, a surfactant, and / or other benefit agent. The topsheet may be hydrophilic or hydrophobic, or may have hydrophilic and / or hydrophobic portions or layers. If the topsheet is hydrophobic, there will typically be perforations so that body exudates can pass through the topsheet.

[0022] A nonwoven web having a visually discernible pattern may be used as a topsheet positioned over one or more visually distinct graphics on a backsheet film to achieve the benefits of the present disclosure.

[0023] Back sheet The backsheet 28 is generally that portion of the absorbent article 10 disposed adjacent the garment-facing surface of the absorbent core 30. The backsheet 28 may be joined to the topsheet 26, the outer cover nonwoven material 40, the absorbent core 30, and / or any other layer portion of the absorbent article by any attachment method known to those skilled in the art. The backsheet 28 prevents or at least inhibits body exudates absorbed and contained in the absorbent core 10 from soiling articles such as bed sheets, undergarments, and / or clothing. The backsheet is typically liquid impermeable, or at least substantially liquid impermeable. The backsheet may be or include a thin plastic film, such as, for example, a thermoplastic film having a thickness of about 0.012 mm to about 0.051 mm. Other suitable backsheet materials may include breathable materials that allow vapors to escape from the absorbent article while still preventing or at least inhibiting body exudates from passing through the backsheet. The backsheet may be provided with one or more visually striking graphics on either its wearer facing surface and / or garment facing surface.

[0024] Outer cover nonwoven material The outer cover nonwoven material (sometimes referred to as a backsheet nonwoven) 40 may comprise one or more nonwoven materials that are joined to and cover the backsheet 28. The outer cover nonwoven material 40 forms at least a portion of the garment-facing surface 2 of the absorbent article 10, and effectively "covers" the backsheet 28 such that no film is present on the garment-facing surface 2.

[0025] A nonwoven web having a visually discernible pattern may be used as an outer cover nonwoven material positioned over one or more visually distinct graphics on a backsheet film to achieve the benefits of the present disclosure.

[0026] Absorbent Core As used herein, the term "absorbent core" 30 refers to the component of the absorbent article 10 that has the greatest absorbent capacity and includes the absorbent material. With reference to Figures 9-11, in some examples, the absorbent material 72 can be disposed within a core bag or core wrap 74. The absorbent material can be contoured or uncontoured depending on the particular absorbent article. The absorbent core 30 can include, consist essentially of, or consist of a core wrap, an absorbent material 72, and a size agent encapsulated within the core wrap. The absorbent material can include superabsorbent polymer, a mixture of superabsorbent polymer and airfelt, airfelt only, and / or a high internal phase emulsion foam. In some examples, the absorbent material can include at least 80%, at least 85%, at least 90%, at least 95%, at least 99%, or up to 100% superabsorbent polymer by weight of the absorbent material. In such examples, the absorbent material can be free of airfelt or at least largely free of airfelt. The absorbent core periphery may be the periphery of the core wrap, but may define any suitable shape, such as, for example, a rectangle, a "T," "Y," "hourglass," or "dogbone" shape. An absorbent core periphery having an approximate "dogbone" or "hourglass" shape may taper along its width toward the crotch region 14 of the absorbent article 10.

[0027] 9-11, the absorbent core 30 can have areas with little or no absorbent material 72 that can join the wearer-facing surface of the core bag 74 with the garment-facing surface of the core bag 74. These areas with little or no absorbent material can be referred to as "channels" 76. These channels can be embodied in any suitable shape and any suitable number of channels can be provided. In other examples, the absorbent core can be embossed to provide indentations in the channels. The absorbent cores of FIGS. 9-11 are merely exemplary absorbent cores. Many other absorbent cores, with or without channels, are within the scope of this disclosure.

[0028] Barrier leg cuffs / leg elastic For example, referring to Figures 1 and 2, the absorbent article 10 may include one or more pairs of barrier leg cuffs 32 and one or more pairs of leg elastics 34. The barrier leg cuffs 32 may be located laterally inward of the leg elastics 34. Each barrier leg cuff 32 may be formed by a piece of material that extends upwardly from the wearer-facing surface 4 of the absorbent article 10 and is bonded to the absorbent article 10 to provide improved containment of body exudates near the junction of the wearer's torso and legs. The barrier leg cuffs 32 are bounded by a proximal edge that is bonded directly or indirectly to the topsheet and / or backsheet, and a free terminal edge that is intended to contact and form a seal with the wearer's skin. The barrier leg cuffs 32 may extend at least partially between the front edge 18 and the rear edge 20 of the absorbent article 10 on either side of the central longitudinal axis 50, and may be present at least in the crotch region 14. The barrier leg cuffs 32 may each include one or more elastics 33 (e.g., elastic strands or strips) near or at their free terminal edges. These elastics 33 aid the barrier leg cuffs 32 in forming a seal around the legs and torso of the wearer. The leg elastics 34 extend at least partially between the front edge 18 and the rear edge 20. The leg elastics 34 essentially aid the portions of the absorbent article 10 proximate the chassis side edges 22, 24 in forming a seal around the legs of the wearer. The leg elastics 34 may extend at least into the crotch region 14.

[0029] Waistband 1 and 2, the absorbent article 10 may include one or more elastic or non-elastic waistbands 36. The elastic waistbands 36 may be disposed on the garment facing surface 2 or the wearer facing surface 4. As an example, a first elastic waistband 36 may be present near the front belt edge 18 of the front waist region 12 and a second elastic waistband 36 may be present near the rear edge 20 of the rear waist region 16. The elastic waistbands 36 may seal the absorbent article 10 around the waist of the wearer and at least help prevent body exudates from leaking out of the absorbent article 10 through the waist opening perimeter. In some examples, the elastic waistbands may completely surround the waist opening perimeter of the absorbent article.

[0030] A nonwoven web having a visually discernible pattern may be used as part of a waistband positioned over one or more visually distinct graphics on a backsheet film to achieve the benefits of the present disclosure.

[0031] Captured material With reference to Figures 1, 2, 7, and 8, one or more acquisition materials 38 may be at least partially intermediate the topsheet 26 and the absorbent core 30. The acquisition materials 38 are typically hydrophilic materials that provide significant wicking of body exudates. These materials can dehydrate the topsheet 26 and rapidly transfer body exudates into the absorbent core 30. The acquisition materials 38 can include, for example, one or more nonwoven webs, foams, cellulosic materials, crosslinked cellulosic materials, airlaid cellulosic nonwoven webs, spunlace materials, or combinations thereof. In some examples, a portion of the acquisition material 38 may extend through a portion of the topsheet 26, a portion of the topsheet 26 may extend through a portion of the acquisition material 38, and / or the topsheet 26 may be nested with the acquisition material 38. Typically, the acquisition material 38 may have a width and length that is less than the width and length of the topsheet 26. The acquisition material can be a secondary topsheet in the context of a feminine pad. The acquisition material may have one or more channels (including embossed versions) as described above with respect to absorbent core 30. The channels of the acquisition material may or may not be aligned with the channels of absorbent core 30. In one example, a first acquisition material may include a nonwoven web and a second acquisition material may include a crosslinked cellulosic material.

[0032] Landing Zone 1 and 2, the absorbent article 10 may have a landing zone area 44 formed in a portion of the garment-facing surface 2 of the outer cover nonwoven material 40. The landing zone area 44 may be located in the rear waist region 16 if the absorbent article 10 is fastened front-to-back, or may be located in the front waist region 12 if the absorbent article 10 is fastened back-to-front. In some examples, the landing zone 44 may be or may include one or more separate nonwoven materials attached to a portion of the outer cover nonwoven material 40 in the front waist region 12 or the rear waist region 16, depending on whether the absorbent article is front-fastened or back-fastened. In essence, the landing zone 44 is configured to receive the fastener 46 and may include a plurality of loops configured to be engaged with a plurality of hooks of the fastener 46, or vice versa.

[0033] A nonwoven web having a visually discernible pattern may be used as a landing zone positioned over one or more visually distinct graphics on a backsheet film to achieve the benefits of the present disclosure.

[0034] Wetness Indicator / Graphic With reference to FIG. 1 , the absorbent article 10 of the present disclosure may include a graphic 78 and / or wetness indicator 80 that is visible from the garment facing surface 2. The graphic 78 may be printed on the landing zone 40, the backsheet 28, and / or other locations. The wetness indicator 80 is typically applied to the absorbent core facing surface of the backsheet 28 such that it may come into contact with body exudates within the absorbent core 30. In some examples, the wetness indicator 80 may form part of the graphic 78. For example, the wetness indicator may appear or disappear, forming / removing text within some graphics. In other examples, the wetness indicator 80 may be in harmony with the graphic 78 (e.g., same design, same pattern, same color) or may not be in harmony with the graphic 78.

[0035] Front and back ears 1 and 2, as referenced above, the absorbent article 10, in the context of a taped diaper, may have front ears 47 and / or back ears 42. In most taped diapers, only one set of ears may be required. The set of ears may include fasteners 46 configured to engage with the landing zone or landing zone area 44. If two sets of ears are provided, in most instances, only one set of ears may have fasteners 46 and the other set may be fastener-free. The ears or portions thereof may be elastic or may have elastic panels. In one embodiment, an elastic film or elastic strands may be disposed intermediate the first nonwoven web and the second nonwoven web. The elastic film may be perforated or non-perforated. The ears may be molded. The ears may be integral (e.g., an extension of the outer cover nonwoven material 40, the backsheet 28, and / or the topsheet 26) or may be separate components attached to the wearer-facing surface 4, the garment-facing surface 2, or intermediate the two surfaces 4, 2 of the chassis 52 of the absorbent article.

[0036] Sensors Referring again to FIG. 1 , the absorbent article of the present disclosure may include a sensor system 82 for monitoring changes within the absorbent article 10. The sensor system 82 may be separate from or integral to the absorbent article 10. The absorbent article 10 may include sensors capable of sensing various aspects of the absorbent article 10 associated with the generation of body exudates such as urine and / or feces (e.g., the sensor system 82 may sense variations such as temperature, humidity, the presence of ammonia or urea, various vapor components of the exudates (urine and feces), changes in the moisture permeability of the garment facing layer of the absorbent article, changes in translucency of the garment facing layer, and / or changes in color of the garment facing layer). In addition, the sensor system 82 may sense components of urine such as ammonia or urea, and / or by-products resulting from the reaction of these components with the absorbent article 10. The sensor system 82 may sense by-products resulting when urine mixes with other components of the absorbent article 10 (e.g., adhesive, AGM). These components or by-products to be sensed may be present as vapors that can pass through the garment facing layer. It may also be desirable to place reactive substances in the absorbent article that, when mixed with urine or feces, change state (e.g., color, temperature) or produce measurable by-products. The sensor system 82 may also sense changes in pH, pressure, odor, the presence of gas, blood, chemical or biological markers, or combinations thereof. The sensor system 82 may have components on or in close proximity to the absorbent article that transmit a signal to a receiver that is more distal from the absorbent article, such as an iPhone. The receiver may output a result that communicates the status of the absorbent article 10 to a caregiver. In other examples, a receiver may not be provided, but instead the status of the absorbent article 10 may be visually or audibly apparent from a sensor on the absorbent article.

[0037] package The absorbent articles of the present disclosure may be placed in a package. The package may include a nonwoven web, a polymeric film, and / or other materials. Graphics and / or indicia relating to the characteristics of the absorbent article may be formed, printed, positioned, and / or disposed on the exterior portion of the package. Each package may include multiple absorbent articles. The absorbent articles may be packaged under compression to reduce the size of the package while providing an appropriate number of absorbent articles per package. Packaging the absorbent articles under compression allows caregivers to easily handle and store the package, and may also provide manufacturers with reduced distribution costs due to the size of the package. Nonwoven webs with visually identifiable patterns and improved texture perception may be used as the nonwoven component of the package, or as part thereof.

[0038] Sanitary napkins Referring to FIG. 12, the absorbent article of the present disclosure may be a sanitary napkin 110. The sanitary napkin 110 may include a liquid permeable topsheet 114, a liquid impermeable or substantially liquid impermeable backsheet 116, and an absorbent core 118. The liquid impermeable backsheet 116 may or may not be vapor permeable. The absorbent core 118 may have any or all of the features described herein with respect to the absorbent core 30, and in some forms may have a secondary topsheet 119 (STS) instead of the acquisition material disclosed above. The STS 119 may include one or more channels (including embossed versions) as described above. In some forms, the channels of the STS 119 may be aligned with the channels of the absorbent core 118. The sanitary napkin 110 may also include wings 120 extending outwardly relative to the longitudinal axis 180 of the sanitary napkin 110. The sanitary napkin 110 may also include a lateral axis 190. The wings 120 may be joined to the topsheet 114, the backsheet 116, and / or the absorbent core 118. The sanitary napkin 110 may also include a front edge 122, a rear edge 124 longitudinally opposite the front edge 122, a first side edge 126, and a second side edge 128 longitudinally opposite the first side edge 126. The longitudinal axis 180 may extend from a midpoint of the front edge 122 to a midpoint of the rear edge 124. The lateral axis 190 may extend from a midpoint of the first side edge 128 to a midpoint of the second side edge 128. The sanitary napkin 110 may also include additional features commonly found in sanitary napkins as known in the art.

[0039] A nonwoven web having a visually distinct pattern can be used as a topsheet of a sanitary napkin, positioned over one or more visually distinct graphics on a backsheet film, to achieve the advantages of the present disclosure. In one example, the overlap between the visually distinct pattern and one or more visually distinct graphics can occur within a wing. Since an absorbent core or a secondary topsheet may not be present within the wing, the perception of the visually distinct graphics within the wing through the topsheet can be improved.

[0040] Nonwoven web having a visually discernible pattern - Patents.com Now consider nonwoven webs having one or more visually distinct patterns. The nonwoven webs disclosed herein are not soluble in liquids such as water. The visually distinct patterns can be formed by three-dimensional features. Such nonwoven webs can be used as various components or components of absorbent articles, such as, for example, topsheets, topsheet portions of sanitary napkin wings, outer cover nonwoven materials, belt portions, waistbands, and / or landing zones.

[0041] Any of the nonwoven webs of the present disclosure may be through-air bonded such that bonds occur at the intersections of individual fibers when hot air is passed through the nonwoven web. Through-air bonding may help maintain the flexibility of the nonwoven web compared to more traditional calendar bonding. Other bonding methods may include calendar point bonding, ultrasonic bonding, latex bonding, hydroentanglement, resin bonding, and / or combinations thereof.

[0042] Any nonwoven web of the present disclosure may constitute part or all of the components of an absorbent article. As discussed above, the absorbent article may comprise a liquid permeable topsheet, a liquid impermeable backsheet, and an absorbent core positioned at least partially intermediate the topsheet and the backsheet. The absorbent article may include an outer cover nonwoven material that forms at least a portion of the garment-facing surface of the absorbent article. The outer cover nonwoven material and / or the topsheet may comprise a nonwoven web of the present disclosure. Other components of the absorbent article, or portions thereof, such as, for example, the belt, landing zone, wings of a sanitary napkin, and / or waistband, may also comprise a nonwoven web of the present disclosure.

[0043] A nonwoven web for absorbent articles is provided. The nonwoven web may form a portion of the laminate of the present disclosure in combination with at least a backsheet film having one or more visually distinct graphics. The nonwoven web may comprise a first surface, a second surface, and a visually identifiable pattern of three-dimensional features on the first surface or the second surface. The three-dimensional features may comprise a first region and a second region. The first region may differ from the second region in an average intensive value, the average intensive being basis weight, volume density, and / or caliper. The first region may form about 5% to about 40%, about 10% to about 35%, about 10% to about 30%, or about 10% to about 25% of the nonwoven web, with all 1% increments specifically recited within the specified ranges and all ranges formed therein or thereby, relative to the total area of ​​the nonwoven web, and the second region forms the remainder of the nonwoven web.

[0044] Nonwoven webs containing a visually distinguishable pattern of three-dimensional features may have a basis weight range according to the basis weight test herein, from about 10 gsm to about 100 gsm, from about 10 gsm to about 60 gsm, from about 15 gsm to about 50 gsm, from about 15 gsm to about 45 gsm, from about 20 gsm to about 40 gsm, from about 20 gsm to about 35 gsm, from about 20 gsm to about 30 gsm, with all 0.1 gsm increments specifically recited within and within all ranges formed by the ranges.

[0045] A visually distinct pattern of three-dimensional features can be formed in the nonwoven web by embossing, hydroentangling, or by using a structured forming belt to lay down the fibers. The pattern can be formed by embossing or hydroentangling a first region or a second region using embossing or hydroentangling. Structured forming belts are discussed herein.

[0046] material The nonwoven webs of the present disclosure may be formed by mechanical web formation, such as dry-laid processes using short staple fibers, and carding processes. The resulting webs may be bonded using irregular pattern heat embossing or hydroforming / hydroentangling processes. The nonwoven webs may also include cotton or other natural fibers. The nonwoven webs of the present disclosure may also be co-formed webs. Co-formed webs typically include a matrix of meltblown fibers mixed with at least one additional fibrous organic material, such as, for example, fluff pulp, cotton, and / or rayon. The co-formed webs may be further structured by embossing or laying the composite on a structured belt during the co-forming process. In one example, when the nonwoven web is made on a structured forming belt, continuous spunbond fibers are used in producing the nonwoven web (as described below). The nonwoven web may include continuous monocomponent polymeric filaments that include a primary polymeric component. The nonwoven web may include continuous multicomponent polymeric filaments that include a primary polymeric component and a secondary polymeric component. The filament may be a continuous bicomponent filament comprising a primary polymer component A and a secondary polymer component B. The bicomponent filament has a cross-section, a length, and a circumferential surface. Components A and B may be disposed in substantially distinct zones across the cross-section of the bicomponent filament and may extend continuously along the length of the bicomponent filament. The secondary component B constitutes at least a portion of the circumferential surface of the bicomponent filament continuously along the length of the bicomponent filament. The polymer components A and B may be melt spun into a multicomponent fiber with conventional melt spinning equipment. The equipment may be selected based on the desired configuration of the multicomponent. Commercially available melt spinning equipment is available from Hills, Inc., Melbourne, Florida. Spinning temperatures range from about 180° C. to about 230° C. The bicomponent spunbond filaments may have an average diameter of, for example, about 6 micrometers to about 40 micrometers, or about 12 micrometers to about 40 micrometers.

[0047] Components A and B can be arranged in a side-by-side configuration as shown in FIG. 13A or in an eccentric sheath / core configuration as shown in FIG. 13B to obtain filaments exhibiting natural helical crimp. Alternatively, components A and B can be arranged in a concentric sheath / core configuration as shown in FIG. 13C. Additionally, components A and B can be arranged in a multi-lobal sheath / core configuration as shown in FIG. 14. Other multicomponent fibers can be produced using the compositions and methods of the present disclosure. Bicomponent and multicomponent fibers can be in a segmented pie configuration, ribbon configuration, islands-in-the-sea configuration, or any combination thereof. The sheath can be continuous or discontinuous around the core. The fibers of the present disclosure can have different geometries, including circular, elliptical, star, rectangular, and various other geometries. Methods for extruding multicomponent polymer filaments into such configurations are generally known to those skilled in the art.

[0048] A wide variety of polymers are suitable for practicing the present disclosure, including polyolefins (such as polyethylene, polypropylene, and polybutylene), polyesters, polyamides, polyurethanes, elastomeric materials, and the like. Non-limiting examples of polymeric materials that can be spun into filaments include natural polymers (such as starch, starch derivatives, cellulose and cellulose derivatives, hemicellulose, hemicellulose derivatives, chitin, chitosan, polyisoprene (cis and trans), peptides, polyhydroxyalkanoates, and the like), as well as synthetic polymers (thermoplastic polymers such as polyesters, nylons, polyolefins (such as polypropylene, polyethylene, polyvinyl alcohol, and polyvinyl alcohol derivatives), sodium polyacrylate (absorbent gelling materials), and copolymers of polyolefins such as polyethylene-octene or polymers made of monomer blends of propylene and ethylene, as well as biodegradable or compostable polymers such as polylactic acid filaments, polyvinyl alcohol filaments, and polycaprolactone filaments). Examples of suitable thermoplastic polymers include, but are not limited to, thermoplastic polymers. In one example, the thermoplastic polymer is selected from the group consisting of polypropylene, polyethylene, polyester, polylactic acid, polyhydroxyalkanoates, polyvinyl alcohol, polycaprolactone, styrene butadiene styrene block copolymers, styrene isoprene styrene block copolymers, polyurethanes, and mixtures thereof. In another example, the thermoplastic polymer is selected from the group consisting of polypropylene, polyethylene, polyester, polylactic acid, polyhydroxyalkanoates, polyvinyl alcohol, polycaprolactone, and mixtures thereof. Alternatively, the polymer may include a polymer derived from a monomer that is bio-based, such as, for example, bio-polyethylene, bio-polypropylene, bio-PET, or PLA.

[0049] The primary component A and secondary component B can be selected such that the resulting bicomponent filaments provide improved nonwoven adhesion and softness. The primary polymer component A may have a melting point lower than the melting point of the secondary polymer component B.

[0050] The primary polymer component A may include polyethylene, polypropylene, or a random copolymer of propylene and ethylene. The secondary polymer component B may include polypropylene, or a random copolymer of propylene and ethylene. The polyethylene may include linear low density polyethylene and high density polyethylene. Additionally, the secondary polymer component B may include polymers that are additives to enhance the natural helical crimp of the filaments, reduce the bonding temperature of the filaments, and increase the abrasion resistance, strength, and flexibility of the resulting fabric.

[0051] For example, inorganic fillers such as oxides of magnesium, aluminum, silicon, and titanium may be added as inexpensive fillers or processing aids. Pigments and / or color melt additives may also be added.

[0052] The fibers of the nonwoven webs disclosed herein may further comprise a lubricant in an amount sufficient to impart a desirable tactile feel to the fibers. As used herein, "lubricant" or "slip agent" refers to an external lubricant. When melt mixed with a resin, the slip agent slowly exudes or migrates to the surface during cooling or after manufacture to form a uniform, imperceptibly thin coating, thereby providing a permanent lubricating effect. The slip agent may be a fast bloom slip agent.

[0053] During manufacture, or in post-treatment, or even both, the nonwoven webs of the present disclosure can be treated with surfactants or other agents to hydrophilize the web or to hydrophobize the web. For example, a nonwoven web used as a topsheet can be made permeable to bodily exudates such as urine and menses by treating it with a hydrophilizing material or surfactant. In other absorbent articles, the nonwoven web can be kept in its natural hydrophobic state or can be made even more hydrophobic by adding a hydrophobizing agent or surfactant.

[0054] Materials suitable for preparing the multicomponent filaments of the nonwoven webs of the present disclosure can include PP3155 polypropylene available from Exxon Mobil Corporation and PP3854 polypropylene available from Exxon Mobil Corporation.

[0055] Structured forming belt and process for producing nonwoven webs As mentioned above, the nonwoven web of the present disclosure can be made by embossing, hydroentangling, or by using a structured forming belt for laying down the fibers or filaments. The structured forming belt and manufacturing process will now be described in more detail. The nonwoven web can be formed directly on the structured forming belt in a single forming process using continuous spunbond filaments. The nonwoven web can exhibit a shape and texture that corresponds to the shape and texture of the structured forming belt.

[0056] The present disclosure may utilize the process of melt spinning. Melt spinning may occur at about 150°C to about 280°, or about 190° to about 230°. The fiber spinning speed may be greater than 100 m / min, for example, about 1,000 to about 10,000 m / min, about 2,000 to about 7,000 m / min, or about 2,500 to about 5,000 m / min. The spinning speed may affect the brittleness of the spun fiber, but generally the higher the spinning speed, the less brittle the fiber. Continuous fibers may be produced by spunbonding or meltblown processes.

[0057] 15, an exemplary process line 330 for manufacturing several exemplary nonwoven webs made on the structured forming belt of the present disclosure is shown. Although the process line 330 is configured to produce a nonwoven web of bicomponent continuous filaments, it should be understood that the present disclosure also encompasses nonwoven webs made with multicomponent filaments having one component, or more than two components. The bicomponent filaments may or may not be trilobal.

[0058] The process line 330 may include a pair of extruders 332 and 334 driven by extruder drives 331 and 333, respectively, for separately extruding a primary polymer component A and a secondary polymer component B. Polymer component A may be fed to the corresponding extruder 332 from a first hopper 336, and polymer component B may be fed to the corresponding extruder 334 from a second hopper 338. Polymer components A and B may be fed from the extruders 332 and 334 through respective polymer conduits 340 and 342 to filters 344 and 345 and melt pumps 346 and 347, which pump the polymer to a spin pack 348. Spinnerets for extruding bicomponent filaments are commonly known to those skilled in the art.

[0059] Generally speaking, the spin pack 348 includes a housing that includes multiple plates stacked on top of each other with a pattern of openings arranged to form flow paths for separately directing the polymer components A and B through the spinneret. The spin pack 348 has openings arranged in one or more rows. The spinneret openings form a curtain of filaments that extend downward as the polymer is extruded from the spinneret. For purposes of this disclosure, the spinneret may be configured to form side-by-side eccentric sheath / core or sheath / core bicomponent filaments as shown in Figures 13A-13C, as well as non-circular fibers such as trilobal fibers as shown in Figure 14. Additionally, the fibers may be monocomponent, having one polymer component, such as, for example, polypropylene.

[0060] The process line 330 may include a quench blower 350 positioned adjacent to the curtain of filaments extending from the spinneret. Air from the quench air blower 350 may quench the filaments extending from the spinneret. The quench air may be delivered from one side of the filament curtain or from both sides of the filament curtain.

[0061] An attenuator 352 may be positioned below the spinneret and may receive the quenched filaments. Fiber draw units or aspirators used as attenuators in melt spinning of polymers are generally known in the art. Fiber draw units suitable for use in the process of forming the nonwoven web of the present disclosure may include straight fiber attenuators of the type shown in U.S. Pat. No. 3,802,817, and eductive guns of the type shown in U.S. Pat. No. 3,692,618 and U.S. Pat. No. 3,423,266.

[0062] Generally speaking, the attenuator 352 may include an elongated vertical passageway through which the filaments are drawn by drawing air entering from the sides of the passageway and flowing down the passageway. A structured, endless, at least partially foraminous forming belt 360 may be disposed below the attenuator 352 and may receive the continuous filaments from the exit opening of the attenuator 352. The forming belt 360 may travel around guide rollers 362. A vacuum device 364 disposed below the portion of the structured forming belt 360 where the filaments are deposited draws the filaments against the forming surface. In FIG. 15, the forming belt 360 is shown as a belt, but it should be understood that the forming belt may take other forms, such as a drum. Details of certain shaped forming belts are described below.

[0063] In operation of process line 330, hoppers 336 and 338 are filled with respective polymer components A and B. Polymer components A and B are melted and extruded by respective extruders 332 and 334 through polymer conduits 340 and 342 and spin pack 348. The temperature of the molten polymer will vary depending on the temperature of the polymer used, but when polyethylene is used as primary component A and secondary component B, respectively, the polymer temperature can range, for example, from about 190° C. to about 240° C.

[0064] As the extruded filaments extend below the spinneret, airflow from quench blower 350 at least partially quenches the filaments and, for certain filaments, induces crystallization of the molten filaments. The quench air may flow in a direction substantially perpendicular to the length of the filaments at a temperature of about 0° C. to about 35° C. and a speed of about 100 to about 400 feet per minute. The filaments may be quenched sufficiently prior to collection on forming belt 360 to allow the filaments to be aligned by forced air passing through the filaments and forming belt 360. Quenching the filaments reduces the tackiness of the filaments so that they do not stick too closely to one another before being bonded together, allowing the filaments to be moved or aligned on forming belt 360 during collection of the filaments on forming belt 360 and during formation of the nonwoven web.

[0065] After quenching, the filaments are drawn by the flow of the fiber draw unit into the vertical passage of the attenuator 352. The attenuator may be positioned 30-60 inches below the bottom of the spinneret.

[0066] The filaments may be deposited through the exit openings of the attenuator 352 onto a shaped, moving forming belt 360. As the filaments contact the forming surface of the forming belt 360, a vacuum device 364 draws air and the filaments against the forming belt 360 to form a nonwoven web of continuous filaments that conforms to the shape of the structured forming surface of the structured forming belt 360. As discussed above, the filaments are quenched so that they do not become excessively tacky, and the vacuum may move or align the filaments on the forming belt 360 as they are collected on the forming belt 330 and formed into a nonwoven web.

[0067] The process line 330 may include one or more bonding devices, such as cylindrical compression rolls 370 and 372 that form a nip through which the nonwoven web may be compressed (e.g., calendered), and the compression rolls may also be heated to bond the fibers. One or both of the compression rolls 370, 372 may be heated to provide enhanced properties and benefits to the nonwoven web by bonding portions of the nonwoven web. For example, it is believed that sufficient heating to provide thermal bonding improves the tensile properties of the nonwoven web. The compression rolls may be a pair of smooth stainless steel rolls with independent heating controls. The compression rolls may be heated by electrical elements or by circulation of hot oil. The gap between the compression rolls may be hydraulically controlled to apply a desired pressure to the nonwoven web as it passes through the compression rolls on the forming belt. As an example, if the forming belt has a caliper of 1.4 mm and the spunbond nonwoven web has a basis weight of 25 gsm, the nip gap between compaction rolls 370 and 372 may be approximately 1.4 mm.

[0068] The upper consolidation roll 370 can be heated sufficiently to consolidate or melt the fibers on the first surface of the nonwoven web 310, thereby providing strength to the nonwoven web so that it can be removed from the forming belt 360 without losing its integrity. For example, as shown in Figures 16 and 17, the belt 360 with the spunbond web thereon enters a nip formed by the rolls 370 and 372 as the rolls 370 and 372 rotate in the direction indicated by the arrows. The heated roll 370 can form bonded fibers 380 on at least the first surface of the nonwoven web 310 by heating the portions of the nonwoven 310 (i.e., areas 321) that are pressed against the roll 370 by the raised resin elements of the belt 360. As will be understood from the description herein, the bonded areas thus formed can have the pattern of the raised elements of the forming belt 360. By adjusting the temperature and residence time, the bonding can be limited primarily to the fibers closest to the first surface of the nonwoven web 310, or the thermal bonding can be performed to the second surface. The bonding can also be a discontinuous network, for example, as point bonds 390, discussed below.

[0069] The raised elements of the forming belt 360 can be selected to establish various network characteristics of the bonded areas of the forming belt and nonwoven web 310. The network corresponds to the resin that makes up the raised elements of the forming belt 360 and can include substantially continuous, substantially semi-continuous, discontinuous, or combinations of these options. As the forming belt 360 is associated with a network appearance, these networks can be descriptive of the raised elements of the forming belt 360, or these networks can be XY planar structures of the forming belt 360, or they can be three-dimensional features of the nonwoven web 310.

[0070] After compression, the nonwoven web 310 may leave the forming belt 360 and be calendered through a nip formed by calender rolls 371, 373, after which the nonwoven web 310 may be wound onto a reel 375 or transported directly to a manufacturing operation for products such as absorbent articles. As shown in the schematic cross-section of FIG. 18, these calender rolls 371, 373 may be stainless steel rolls having an engraved pattern roll 384 and a smooth roll 386. The engraved roll may have raised portions 388 that may provide additional compression and bonding to the nonwoven web 310. The raised portions 388 may be a regular pattern of relatively small, spaced apart "pins" that form a pattern of relatively small point bonds 390 in the nip of the calender rolls 371 and 373. The percentage of point bonds in the nonwoven web 10 may be, for example, from about 3% to about 30%, or from about 7% to about 20%. The engraved pattern can be in the form of a plurality of closely spaced, regular, generally cylindrical, generally flat-topped pins, with pin heights ranging, for example, from about 0.5 mm to about 5 mm, or from about 1 mm to about 3 mm. The pin-bonding calendar roll can form closely spaced, regular point bonds 390 in the nonwoven web 10, as shown in the example of Figure 19. Further bonding can be achieved, for example, by hot air through-bonding. Figure 19 shows a heart-shaped pattern made by the same structured forming belt technique that can be used to make the nonwoven webs of the present disclosure.

[0071] As used herein, "point bonding" refers to a method of thermally bonding a nonwoven web. The method involves passing the web through a nip between two rolls: a heated male pattern or engraved metal roll and a smooth or patterned metal roll. The male pattern roll can have a number of raised, generally cylindrical pins that create circular point bonds. The smooth roll can be heated or unheated depending on the application. In a nonwoven manufacturing line, a nonwoven web, which may be an unbonded nonwoven web, is fed into a calender nip where the fiber temperature is raised to a point where the fibers are thermally fused together at the tips of the engraved points against the smooth roll. Heating times are typically on the order of a few milliseconds. The properties of the nonwoven web depend on the process settings such as roll temperature, web line speed, and nip pressure, all of which can be determined by one skilled in the art to obtain the desired degree of point bonding. Other types of point bonding, commonly known as high temperature calender bonding, can use different geometric shapes to create the bond (other than circular), such as ellipses, lines, circles, etc. In one embodiment, the point bonds produce a pattern of point bonds that are 0.5 mm diameter circles with 10% of the total bonded area. Other bond geometries can include, for example, raised pins with the longest dimension across the pin's bonded surface of about 0.1 mm to 2.0 mm, with the total bonded area ranging from about 5% to about 30%.

[0072] As shown in Figure 19, a heated consolidation roll 370 can form a bond pattern, which may be a substantially continuous network bond pattern 380 (e.g., interconnected heart-shaped bonds), on a first surface (not shown in Figure 19 because it is oriented away from the viewer) of the nonwoven web 310, and an engraved calendar roll 373 can form relatively small point bonds 390 on a second surface 314 of the nonwoven web. The point bonds 390 can fix loose fibers that would otherwise cause fraying or pilling during use of the nonwoven web 310. The benefits of the resulting structure of the nonwoven web 310 are most apparent when used, for example, as a topsheet or outer cover nonwoven material for absorbent articles such as diapers. When used in absorbent articles, the first surface of the nonwoven web 310 can be relatively flat (compared to the second surface 14) and can have relatively more adhesion to form bonds 380 in areas of the nonwoven web where the heated compression roll is pressed by the raised elements of the forming belt 360. This adhesion provides structural integrity to the nonwoven web 310, but can still be relatively hard or rough against the skin of the user. Thus, the first surface of the nonwoven web 310 can be oriented in a diaper or sanitary napkin facing the inside of the article, i.e., away from the wearer's body, or facing the garment. Similarly, the second surface 314 can face and contact the wearer during use. The relatively small point bonds 390 can be less visually or tactilely perceptible by the user, and the relatively soft three-dimensional features can remain free of visually noticeable fuzzing and pilling while feeling soft to the body during use. Additional adhesion can be used instead of or in addition to the above-mentioned adhesions. Through-air bonding can also be used.

[0073] The forming belt 360 may be manufactured according to the methods and processes described in U.S. Patent No. 6,610,173 issued to Lindsay et al. on August 26, 2003, or U.S. Patent No. 5,514,523 issued to Trokhan et al. on May 7, 1996, or U.S. Patent No. 6,398,910 issued to Burazin et al. on June 4, 2002, or U.S. Patent No. 8,940,376 issued to Stage et al. on January 27, 2015, each of which has the improved features and patterns disclosed herein for producing spunbond nonwoven webs. Although the disclosures by Lindsay, Trokhan, Burazin, and Stage describe structured forming belts representative of papermaking belts made of cured resin on woven reinforcement members, these belts may, with modifications, be utilized to form the nonwoven webs of the present disclosure as described herein.

[0074] One example of a structured forming belt 360 that can be made according to the disclosure of U.S. Pat. No. 5,514,523 is shown in FIG. 20. As taught therein, a reinforcing member 394 (such as a woven belt of filaments 396) is completely coated with a liquid photopolymer resin to a preselected thickness. A film or negative mask incorporating repeating elements of the desired raised element pattern (e.g., FIG. 22) is juxtaposed over the liquid photopolymer. The resin is then exposed to light of an appropriate wavelength through the film (e.g., ultraviolet light for ultraviolet curable resins). This exposure to light hardens the resin in the exposed areas (i.e., the white or non-printed portions of the mask). The uncured resin (resin under the opaque portions of the mask) is removed from the system, leaving behind the cured resin that forms the pattern shown in the figure (e.g., the cured resin elements 392 shown in FIG. 20).

[0075] The forming belt 360 can include cured resin elements 392 on woven fabric reinforcement members 394. The reinforcement members 394 can be made of a filament fabric 396 as is commonly known in the papermaking belt art, such as resin coated papermaking belts. The cured resin elements can have the general structure shown in FIG. 20 and are made using a mask 397 having the dimensions shown in FIG. 22. As shown in the schematic cross-section of FIG. 21, the cured resin elements 392 flow around the reinforcement members 394 and are cured and "set" therein, and can have a width at a distal end (DW) of about 0.020 inches to about 0.060 inches, or about 0.025 inches to about 0.030 inches, and an overall height above the reinforcement members 394, referred to as the over burden (OB), of about 0.030 inches to about 0.120 inches, or about 0.50 inches to about 0.80 inches, or about 0.040 inches. Figure 22 depicts a portion of a mask 397 showing the design and typical dimensions of one repeat unit of the repeating heart design shown herein as an example only. The white portion 398 is transparent to ultraviolet light, which in the belt manufacturing process described in U.S. Patent No. 5,514,523 allows the ultraviolet light to cure the underlying resin layer, which hardens to form raised elements 392 on the reinforcing members 394. After the uncured resin is washed away, a forming belt 360 having a cured resin design as shown in Figure 20 is produced by splicing together both ends of a length of forming belt, which may be determined by the equipment design, as shown in Figure 15.

[0076] The nonwoven webs disclosed herein may be fluid permeable. The entire nonwoven web may be considered fluid permeable, or some regions may be fluid permeable. Fluid permeable as used herein in relation to a nonwoven web means that the nonwoven web has at least one region that allows liquid to pass through under conditions during use of a consumer product or absorbent article. For example, when used as a topsheet of a disposable absorbent article, the nonwoven web may have at least one zone that has a certain level of fluid permeability that allows urine to pass through to the underlying absorbent core. Fluid permeable as used herein in relation to a region means that the region exhibits a porous structure that allows liquid to pass through.

[0077] Due to the nature of the structured forming belt and other equipment elements, as described herein, the three-dimensional features of the nonwoven web have average intensive properties that can differ between a first region and a second region, or can vary from feature to feature, to impart useful properties to the nonwoven web when used in personal care articles, garments, medical supplies, and cleaning products. For example, the first region may have a basis weight or density that is different from the basis weight or density of the second region, which may both have a basis weight or density that is different from the basis weight or density of the third region, thereby imparting beneficial aesthetic and functional properties related to fluid acquisition, distribution, and / or absorbency in diapers or sanitary napkins.

[0078] The difference in average intensive properties between various regions of the nonwoven web is believed to be due to the fiber distribution and compaction resulting from the apparatus and method described herein. The fiber distribution occurs during the fiber laying process, as opposed to a post-manufacturing process, such as an embossing process. The fibers are free to move during processes such as the melt spinning process, and their movement is determined by the nature and air permeability of the forming belt characteristics, as well as other processing parameters, so the fibers are believed to be more stable and permanently formed within the nonwoven web.

[0079] In a structured forming belt having multiple zones, the air permeability of each zone can be varied so that the intensiveness of the average basis weight and average volume density of the zone can be changed. The variable air permeability of the various zones causes the fibers to move during laying. The air permeability can be from about 400 to about 1000 cfm, or from about 400 to about 800 cfm, or from about 500 cfm and about 750 cfm, or from about 650 to about 700 cfm, with all 0.1 cfm increments within the specified ranges and all ranges formed by or within the ranges specifically recited.

[0080] The structured forming belt may comprise an endless, perforated member having a first surface and a second surface, a curable resin extending from the first surface of the perforated member, and a visually distinguishable pattern of three-dimensional features on the endless, perforated member. The three-dimensional features may comprise one or more first regions and a plurality of second regions. The one or more first regions may comprise resin and the plurality of second regions may be free of resin.

[0081] Bio-based ingredients for absorbent article components Components of the disposable absorbent articles (i.e., diapers, disposable pants, adult incontinence articles, sanitary napkins, panty liners, etc.) described herein may be prepared using any of the methods disclosed in U.S. Patent Application Publication No. 2007 / 0219521(A1) published on September 20, 2007 by Hird et al., U.S. Patent Application Publication No. 2011 / 0139658(A1) published on June 16, 201 ... U.S. Patent Application Publication No. 2011 / 0139657(A1), U.S. Patent Application Publication No. 2011 / 0152812(A1) to Hird et al. published June 23, 2011, U.S. Patent Application Publication No. 2011 / 0139662(A1) to Hird et al. published June 16, 2011, and U.S. Patent Application Publication No. 2011 / 0139659(A1) published June 16, 2011. These components include, but are not limited to, the topsheet nonwoven, backsheet film, backsheet nonwoven, side panel nonwoven, barrier leg cuff nonwoven, superabsorbent, nonwoven acquisition layer, core wrap nonwoven, adhesive, fastener hook, and fastener landing zone nonwoven, and film base.

[0082] In some embodiments, the components of the disposable absorbent article comprise a biobased content value of from about 10% to about 100% using ASTM D6866-10, Method B, in other embodiments from about 25% to about 75%, and in yet other embodiments from about 50% to about 60% using ASTM D6866-10, Method B.

[0083] To apply the ASTM D6866-10 methodology to determine the biobased content of any disposable absorbent article component, a representative sample of the disposable absorbent article component must be obtained for testing. In one form, the disposable absorbent article component can be ground into fine particles of less than about 20 mesh using known grinding methods (e.g., a Wiley® mill) and a representative sample of suitable mass can be removed from the randomly mixed particles.

[0084] The nonwoven web may comprise multicomponent or bicomponent fibers, where at least one or more of the components are bio-based. Examples include side-by-side, sheath / core, or islands-in-the-sea configurations, where one or more or all of the components are bio-based.

[0085] The nonwoven web may include bonds at fiber intersections formed by passing hot air through the nonwoven web and using a process called through-air bonding. In another example, the nonwoven web may include calendar bonds configured to bond the fibers together.

[0086] The nonwoven web of the present disclosure may include a second visually distinct pattern of three-dimensional features on the first surface or the second surface. The second visually distinct pattern of three-dimensional features may be different from the visually distinct pattern. The three-dimensional features may comprise one or more third regions and a plurality of fourth regions. The one or more third regions may differ from the plurality of fourth regions in average intensive property values, such as basis weight, caliper, and / or volume density.

[0087] The nonwoven webs of the present disclosure can include multicomponent fibers, such as bicomponent fibers (see, e.g., Figures 13A-13C), in which at least one component of the multicomponent fiber can be bio-based, such as, for example, PLA, bio-PE, or bio-PP.

[0088] The nonwoven web may be a spunbond nonwoven web or a carded nonwoven web.

[0089] The nonwoven web of the present disclosure may include low concentrations of colorants, additives, and / or dyes to aid in texture perception, absorbency perception, and softness perception. The low concentration of colorants, additives, and / or dyes may be low enough that the nonwoven web still appears to be "white" to the human eye. For example, if a dark blue-green colorant, additive, and / or dye is used, the resulting nonwoven material still appears to be white to the human eye, but the texture of the nonwoven web is more enhanced when viewed. This results in an improved perception of absorbency and softness.

[0090] As an example, colorant masterbatches, which are solid additives typically containing pigments ranging from about 15% to about 65% active with a carrier resin such as polypropylene, polyethylene, and / or polyester, can be used. Colorant masterbatches are designed to deliver a specific target color, described as the "let-down ratio." For example, in a nonwoven web, a masterbatch with a let-down ratio of 2% will result in a target color when 2% of the masterbatch is blended with 98% of the corresponding nonwoven resin, such as polypropylene, polyethylene, and / or polyester. Conventional let-down ratios can range from about 1.5% to about 5%. However, at this level of let-down ratio, the nonwoven web appears colored to the human eye, for example, a dark teal color. In the present disclosure, this addition level of the masterbatch is significantly lower to enhance texture perception, absorbency perception, and softness perception, and the color is not visible to the human eye (i.e., the nonwoven web still appears white).

[0091] Exemplary colorants can be purchased from Ampacet Corporation, located at 660 White Plans Rd., Tarrytown, NY 10591. One exemplary colorant is a blue colorant under the trade name Ampacet 4600664-N manufactured by Ampacet Corporation.

[0092] Emtec In addition to providing improved texture perception, the nonwoven web of the present disclosure provides improved softness and texture. The present disclosure further resolves the conflict between high softness and high visible texture. According to the Emtec test herein, softness, texture (i.e., smoothness), and / or stiffness can be measured by Emtec Tissue Softness Analyzer. Tactile softness is measured as TS7. Texture / smoothness is measured as TS750. Stiffness is measured as D.

[0093] A portion or all of the nonwoven web of the present disclosure has a thermal conductivity of 15 dB V 2 , or about 1 dB V 2 rms~about 4.5dB V 2 rms, approximately 2dB V 2 rms~about 4.5dB V 2 rms, or about 2 dB V 2 rms ~ approx. 4.0 dB V 2 Some or all of the nonwoven webs of the present disclosure may also have a TS7 value in the range of about 4 dB V 2 rms ~ approx. 30 dB V 2 rms, about 6 dB V 2 rms ~ approx. 30 dB V 2 rms, about 6 dB V 2 rms~about 20dB V 2 rms, about 6 dB V 2 rms~about 15dB V 2 rms, about 6 dB V 2 rms ~ approx. 12 dB V 2 rms, or about 6.5 dB V 2 rms ~ approx. 10 dB V 2rms range. A portion or all of the wearer-facing surface of the topsheet of the present disclosure may also have a D value in the range of about 1 mm / N to about 10 mm / N, about 3 mm / N to about 8 mm / N, about 2 mm / N to about 6 mm / N, about 2 mm / N to about 4 mm / N, or about 3 mm / N to about 4 mm / N. All values ​​are measured according to the Emtec test herein. The TS7 value is tactile softness, so a low number is desired (the lower the number, the softer the material). The TS750 value is texture, so a high number is desired (the higher the number, the more textured the material). Having a low TS7 value and a high texture value is typically a contradiction in that the nonwoven has more texture and is less soft. Applicants, without wishing to be bound by theory, have discovered the unexpected result of a highly textured nonwoven that is still very soft.

[0094] Laminate The laminate of the present disclosure may comprise one or more of the nonwoven webs discussed herein having one or more visually distinct patterns of three-dimensional features, and a backsheet film having one or more visually distinct graphics on the garment-facing or wearer-facing surface. The one or more visually distinct graphics on the backsheet film significantly enhance the perception of the one or more visually distinct patterns of the nonwoven web when the nonwoven web is overlaid with the one or more graphics. The laminate may also comprise other materials. A portion or all of the visually distinct patterns of the three-dimensional features may overlap a portion or all of the one or more graphics. An example laminate is an outer cover nonwoven material positioned on a backsheet film having one or more graphics printed on the garment-facing surface of the backsheet. Another example is a topsheet positioned on a backsheet film having one or more graphics printed on the wearer-facing surface of the backsheet. In some cases, the topsheet may overlap one or more graphics of the backsheet film, at least in the wings of the sanitary napkin, to form a laminate.

[0095] Back seat graphics The garment or wearer facing surface of the backsheet may include one or more graphics. The one or more graphics may comprise visually vivid graphics. Visually vivid graphics may be characterized by a number of characteristics, such as chroma, L, and / or luminance, as discussed further herein. * , a * , b * Color value, L * Value, a * value, or b * The graphic may be characterized by a value. The one or more graphics may be floods of the same or different colors. The floods may cover all of one surface of the backsheet or portions thereof. In other examples, many different graphics may be provided, some repeated. The one or more graphics may include colors, words, slogans, brand names, wetness indicators (or portions thereof), designs, icons, logos, letters, hearts, numbers, size indications, front / back indications, characters, animals, faces, symbols, and the like. The graphics may also include visible location indicia to indicate where the sensor should be attached to the diaper, such as, for example, a dashed outline matching the shape of the sensor. The graphics may be anything printed on the backsheet. The graphics may also be colored areas of the backsheet. The wearer-facing or garment-facing surface of the backsheet may have a non-printed area, a non-colored area, or an area not covered by one or more graphics in the ranges, for example and specifically, from about 5% to about 90%, from about 5% to about 80%, from about 10% to about 80%, from about 10% to about 70%, from about 20% to about 70%, including all 1% increments within the recited ranges and all ranges formed therein or thereby.

[0096] Saturation The saturation value is a measure of the vividness or definition in a backsheet graphic. The one or more visually vivid graphics may have a saturation value of greater than 8 and less than 100, or greater than 8 and less than 90, according to the Backsheet Graphic Color Test herein. The saturation value of the one or more graphics may also be in the range of about 10 to about 95, about 10 to about 90, about 15 to about 80, about 20 to about 75, about 10 to about 60, or about 10 to about 50, according to the Backsheet Graphic Color Test herein.

[0108] Sanitary napkin laminate Referring again to FIG. 12, the sanitary napkin 110 comprises wings 120 and a liquid impermeable backsheet 116. The wearer facing surface 115 or garment facing surface of the backsheet 116 may include one or more visually distinct graphics 400. The one or more graphics 400 may be positioned anywhere on the backsheet 116, such as within the wings 120. The one or more graphics 400 may also be positioned elsewhere on the backsheet 116. The liquid permeable topsheet 114 or a portion thereof may include one or more visually distinct patterns of three-dimensional features 402 on its first or second surface. At least some of the three-dimensional features 402 may each comprise a first region 404 and a second region 406. The first region 404 may have a first value of average intensiveness and the second region 406 may have a second value of average intensiveness. The first and second values ​​may be different. The average intensiveness may be the same as that discussed herein. Part or all of the visually distinct pattern of the three-dimensional features 402 may overlap part or all of the one or more graphics 400. This overlap may occur, for example, in the wings 120 because the absorbent core 118 and secondary topsheet 119 may not be present, and as a result, the one or more graphics 400 may be more visible through the topsheet 114. The one or more visually distinct patterns of the three-dimensional features may be more visible when overlapping with one or more visually distinct graphics. The garment-facing or wearer-facing surface of the liquid permeable topsheet 114 has a minimum of about 15 dB V according to the Emtec test. 2The one or more graphics 400 may have a TS7 value of less than 130, greater than 8 and less than 100, or other saturation values ​​specified herein, according to the Backsheet Graphic Color Test. A portion or all of the one or more graphics 400 may have a chroma value of less than the first L, as measured through a first region 404 of the visually distinguishable pattern of three-dimensional features 402, according to the Nonwoven Backsheet Laminate Color Test. * , a * , b * A portion or all of the one or more graphics 400 may exhibit a different second L color value when measured through a second region 406 of the visually distinguishable pattern of three-dimensional features 402 according to the Nonwoven Backsheet Laminate Color Test. * , a * , b * Some or all of the one or more graphics 400 may exhibit an L value of less than 95 or less than 90 and greater than 5 according to the Nonwoven Backsheet Laminate Color Test. The one or more graphics 400 may also be printed on the secondary topsheet 119 such that they are visible through the topsheet 114. The one or more graphics 400 may also exhibit other chroma values, i.e., L * , a * , b * Color value or individual L * , a * , or b * The color may be expressed as any of the values, delta E values, or other values, such as, for example, non-printed or non-colored areas, as disclosed herein, and for the sake of brevity, will not be repeated here.

[0109] Backsheet / Nonwoven Laminate As mentioned above, laminates of the present disclosure may be formed by a backsheet and one or more nonwoven webs. Additional laminate examples are now considered.

[0110] 23 is a plan view of the liquid impermeable backsheet 28. The backsheet 28 may include one or more visually vivid graphics 400 and a wetness indicator 80. In some cases, the one or more visually vivid graphics 400 may include at least a portion or all of the wetness indicator 80. The backsheet 28 comprises a wearer-facing surface and a garment-facing surface 408 (i.e., facing the outer cover nonwoven material 40). The wearer-facing or garment-facing surface 408 may include one or more graphics 400. The wetness indicator 80 is positioned on the wearer-facing surface 408 and is thus configured to contact body exudates within the absorbent core during wear of the absorbent article 10 and indicate the wetness or fill of the absorbent article 10. The one or more graphics 400 may be of an animal, such as a rabbit, or a cloud, for example. As described herein, the one or more graphics 400 may be numbers, words, and the like. The rabbit or cloud images may be repeated or may all be different in size, shape, color, and / or orientation. One or more of the graphics 400 may exhibit a saturation value according to the Backsheet Graphics Color Test of greater than 8 and less than 130, greater than 8 and less than 100, or other saturation value specified herein. The garment facing surface 408 of the backsheet 28 may have a non-printed or non-colored area of ​​about 5% to about 80% (or other range specified herein) of the total area of ​​the garment facing surface 408 of the backsheet 28. In some cases, the graphic 400 may be formed from a plurality of first repeating units.

[0111] FIG. 24 is a plan view of an outer cover nonwoven material or nonwoven topsheet 410 (410 is referred to as "outer cover nonwoven material 410" but may be a nonwoven topsheet). The outer cover nonwoven material 410 includes a first garment-facing surface and a second wearer-facing surface. In FIG. 24, the garment-facing surface 412 is shown facing the viewer. The outer cover nonwoven material 410 includes one or more visually distinguishable patterns of three-dimensional features 402. It will be understood that the visually distinguishable pattern of three-dimensional features 402 may be present on the garment-facing surface or the wearer-facing surface. At least some of the three-dimensional features may comprise a first region 404 and a second region 406. The first region 404 may have a first value of average intensiveness. The second region 406 may have a second value of average intensiveness. The first and second values ​​of average intensiveness may be different. The average intensive property may be a basis weight, and the basis weights of the first and second regions 404, 406 may both be greater than zero.

When more than one recognizable individual indicia is provided on the backsheet, the outer cover nonwoven material, or the topsheet, the recognizable individual indicia may be the same or different on the various components. Some recognizable individual indicia may be the same and other recognizable individual indicia may be different on the various components. As an example, the backsheet, the outer cover nonwoven material, and / or the topsheet may have from about 1 to about 50, from about 2 to about 40, from about 2 to about 30, from about 2 to about 25, or from about 2 to about 20 recognizable individual indicia, specifically reciting every increment within the specified range and all ranges therein or formed thereby. The recognizable individual indicia may be oriented the same or differently on the same material and / or on different materials. An exemplary laminate having recognizable individual indicia is the outer cover nonwoven material of Figure 29 overlapping the backsheet of Figure 23. In such a format, the recognizable individual indicia of Figure 29 can be coordinated with the recognizable individual indicia of Figure 23 (e.g., rabbits with rabbits and clouds with clouds).

[0117] Stitch-like pattern In addition to the various graphics 400 discussed herein, the backsheet may include a stitch-like pattern on its garment-facing or wearer-facing surface. The stitch-like pattern may surround or partially surround the graphic 400. Typically, the stitch-like pattern does not overlap or overlap the graphic 400. In some cases, the stitch-like pattern may overlap the graphic 400 or a portion thereof. In some cases, the stitch-like pattern may be used without the graphic 400. Figures 30-32 show examples of stitch-like patterns 500. Of course, the graphic 400 may also be present within the stitch-like pattern. A stitch-like pattern on the backsheet paired with an outer cover nonwoven material and / or a topsheet having a visually recognizable pattern disclosed herein provides the absorbent article of the present disclosure with a garment-like soft appearance that is desirable to consumers. As shown in Figures 30 and 31, the stitch-like pattern may include a plurality of linear elements 502. In an absorbent article, the linear elements 502 typically extend in a direction generally parallel to the central longitudinal axis of the absorbent article, but may extend in other directions as well. Generally, in this context, generally parallel means ±10 degrees to the central longitudinal axis of the absorbent article. The linear elements may also extend within a range of about 11 degrees to about 90 degrees to the central longitudinal axis of the absorbent article, such as, for example, about 45 degrees. The linear elements may be continuous or discontinuous. The linear elements may include arcuate portions to form wavy linear elements. The linear elements may be spaced apart from each other in the horizontal direction by a distance. The distance may range from about 1 mm to about 15 mm, about 1.5 mm to about 15 mm, about 2 mm to about 12 mm, about 2 mm to about 10 mm, about 2 mm to about 8 mm, about 2 mm to about 5 mm, or about 1.5 mm to about 4 mm, with all 0.1 mm increments specifically recited within the specified ranges and all ranges therein or formed by them. The distance between two adjacent linear elements may vary or may be consistent within the stitch-like pattern. Distances of less than 1 mm between linear elements create the impression of a "flood" of color, greatly reducing the aesthetic benefit of the stitch-like pattern.The linear elements themselves may be in the range of about 0.2 mm to about 5 mm, about 0.3 mm to about 5 mm, about 0.4 mm to about 4 mm, or 0.5 to about 3 mm, specifically reciting all 0.1 mm increments within the specified ranges and all ranges therein or formed by them. Two adjacent linear elements 502 may be connected to each other by a plurality of connecting elements 504. The connecting elements 504 may extend approximately horizontally between the linear elements 502 or may extend at a non-horizontal angle. Different connecting elements may extend in the same or different directions. About 5 to about 100 connecting elements 504 may extend between two adjacent linear elements 502. In other stitch-like patterns, such as the pattern shown in FIG. 32, linear elements may not be provided. The stitch-like pattern may cover about 20% to about 95% of the total surface area of ​​the backsheet.

[0118] FIG. 33 is a plan view of a liquid impermeable backsheet with one or more visually distinct graphics. The wetness indicator 80 may or may not include a portion of one or more visually distinct graphics. The backsheet may include a stitch-like pattern as described above. In some cases, it may be desirable to include a non-printed zone, a no-graphics zone, a light-graphics zone, a no-color zone, or a white zone (collectively, "zone 600") surrounding the wetness indicator 80 so that the wetness indicator 80 remains clearly visible to the caregiver and is not obscured by the visually distinct graphics. In other examples, the zone 600 surrounding the wetness indicator 80 may be a different color than at least a portion of the remainder of the graphics and the wetness indicator so that the wetness indicator remains clearly visible to the caregiver. In one example, the zone 600 may be graduated or have a gradient to make the wetness indicator 80 more visible and may have less harsh lines of the graphics / no graphics or color / no color. For example, the graphics in the zones 600 more distal from the wetness indicator 80 may be darker or more visible than the graphics in the zones 600 more proximal to the wetness indicator 80. In another example, the graphics in the zones 600 more distal from the wetness indicator 80 may be visible, while the areas in the zones 600 more proximal to the wetness indicator may not include a graphic or may not include a color. The zones 600 with different colors or graphics or without colors or graphics may completely or at least partially surround the wetness indicator 80.

[0121] Test Method Backsheet Graphic Color Test The chroma value is a measure of the vividness or vividness of the backsheet graphics. Generally, chroma is measured according to the CIE 1976 L * a * b * Color values ​​are calculated from reflectance measurements. Chroma is measured using a spectrophotometer with a computer interface (a suitable instrument is HunterLab LabScan XE running Universal Software available from Hunter Associates Laboratory Inc., Reston, VA). All testing is performed in a conditioned room maintained at about 23±2° C. and about 50±2% relative humidity.

[0122] To obtain the sample, the backsheet film layer of the material is carefully removed from the absorbent article. If necessary, a cryogenic spray (such as Cyto-Freeze (Control Company, Houston TX)) may be used to remove the sample from the underlying layer. An area of ​​the sample containing a uniform color graphic is identified as the test site. If the sample at the test site contains any holes, tears, or other physical deformations, another site will be selected. Ensure that all adhesive and nonwoven fibers are completely removed from the test site. The raw layer of backsheet film material with the graphic, obtained before incorporation into an absorbent article, can also be tested. Precondition the sample for about 2 hours at about 23°C ± 2°C and about 50% ± 2% relative humidity before testing.

[0123] Select the disk with the largest measurement port size that can fit within the selected uniform color graphic test site. Utilize the black tile and then the white tile supplied by the manufacturer and standardize the instrument using the selected port size (instruct the software on the appropriate area view).

[0126] Nonwoven Backsheet Laminate Color Test The purpose of this test is to determine the CIE 1976 L standard deviation of the backsheet graphics visible through the area of ​​the outer cover nonwoven material and / or topsheet. * a * b *The objective is to measure color values ​​and calculate the delta E, or the amount of color difference, between the two regions. Images are acquired using a flatbed scanner (a suitable scanner is an Epson Perfection V750 Pro or equivalent, manufactured by Epson America Inc., Long Beach CA) capable of scanning a minimum of 24-bit color at 2400 dpi with manual control of color management. The scanner is interfaced to a computer running color calibration software capable of calibrating the scanner against a color reflective IT8 target using a corresponding reference file conforming to ANSI method IT8.7 / 2-1993 (a suitable color calibration software is Monaco EZColor or i1Studio, or equivalent, available from X-Rite Grand Rapids, MI). The color calibration software constructs an International Color Consortium (ICC) color profile for the scanner, which is used to color correct the output image using an image analysis program that supports the application of ICC profiles (a suitable program is Photoshop or equivalent, available from Adobe Systems Inc., San Jose, Calif.). The color corrected image is then converted to the CIE L color standard for subsequent color analysis. * a * b * Transform into color space (a suitable image color analysis software is MATLAB available from Mathworks, Inc., Natick, Mass.).

[0127] To obtain the sample, carefully remove the outer cover nonwoven material and backsheet film laminate or topsheet and backsheet film laminate from the absorbent article. If necessary, a low temperature spray (such as Cyto-Freeze (Control Company, Houston TX)) may be used to remove the sample from the underlying layers. A portion of the sample where the visually identifiable pattern of the three-dimensional features of the outer cover nonwoven material or topsheet overlaps with a portion of the uniform color graphic on the backsheet film is identified as the test site. If the sample of the test site contains any holes, tears, or other physical deformations other than the three-dimensional features, a different site will be selected. The outer cover nonwoven material and backsheet film laminate or topsheet and backsheet film laminate with the graphic obtained before being incorporated into the absorbent article can also be tested. Before testing, the sample is preconditioned for about 2 hours at about 23°C ± 2°C and about 50% ± 2% relative humidity.

[0128] Turn on the scanner for 30 minutes prior to calibration and image acquisition. Deselect any automatic color correction or color management options that may be included in the scanner software. If automatic color management cannot be disabled, the scanner is not suitable for this application. Follow the recommended procedures in the color calibration software to create and export an ICC color profile for the scanner. The color calibration software compares the acquired IT8 target images with corresponding reference files to create and export an ICC color profile for the scanner, which is then applied within an image analysis program to correct the color of the subsequent output images.

[0129] Open the scanner lid and carefully lay the sample flat and spread on the center of the scanner glass with the wearer-facing surface (for topsheet / backsheet film laminate) or garment-facing surface (for outer cover nonwoven material / backsheet film laminate) of the test site oriented to the glass. Acquire a scan encompassing the entire test site and import it into image analysis software with 24-bit color at a resolution of 2400 dpi (approximately 94.5 pixels / mm) in reflective mode. Assign an ICC color profile to the image generating a color-corrected sRGB image. Save this calibrated image in an uncompressed format, such as a TIFF file, prior to analysis to preserve the calibrated R, G, B color values.

[0130] Open the sRGB color calibration image in your color analysis software and convert it to CIE L * a * b * Convert to color space. This is accomplished by the following steps: First, scale the sRGB data to the range [0, 1] by dividing each of the values ​​by 255. Then, the compressed sRGB channels (denoted by uppercase (R,G,B), or inclusively V) have been linearized (denoted by lowercase (r,g,b), or inclusively v) when the following operations have been performed on all three channels (R,G,B):

[0137] Air Permeability Test Method The air permeability test is used to measure the amount of air flow in cubic feet per minute (cfm) through the forming belt. The air permeability test is performed on a Texas Instruments model FX3360 Portair air permeability tester available from Textest AG, Sonnenbergstrasse 72, CH 8603 Schwerzenbach, Switzerland. This equipment utilizes a 20.7 mm orifice plate for an air permeability range of 300-1000 cfm. If the air permeability is less than 300 cfm, a smaller orifice plate is required. If it is greater than 1000 cfm, a larger orifice plate is required. By measuring the air permeability at multiple local zones of the forming belt, the difference in air permeability across the forming belt can be measured.

[0138] Test procedure 1. Start the FX3360 device. 2. Select the default method, which has the following settings: a. Material: Standard b. Measurement characteristics: Air Permeability (AP) c. Test pressure: 125 Pa (Pascal) dT coefficient: 1.00 e. Test point pitch: 0.8 inches. 3. Place a 20.7 mm orifice plate at the desired location on the top surface of the forming belt (the surface with the three-dimensional projections). 4. Select “Spot Measurement” on the test fixture touch screen. 5. If necessary, reset the sensor before taking measurements. 6. Once reset, select the "Start" button to begin the measurement. 7. Wait for the reading to stabilize and record the cfm reading on the screen. 8. Select the "Start" button again to stop the measurement.

[0139] Basis Weight Test The basis weight of the nonwoven webs described herein can be measured by a number of available techniques, but a simple representative technique involves taking an absorbent article or other consumer product, removing any elasticity that may be present, and stretching the absorbent article or other consumer product to its full length. 2 A die having an area of ​​10 mm is used to cut a piece of the nonwoven web (e.g., topsheet, outer cover nonwoven material) from approximately the center of the absorbent article or other consumer product in a location that avoids, as much as possible, any adhesive that may be used to fasten the nonwoven web to any other layers that may be present and the nonwoven web from being detached from the other layers (using a low temperature spray such as Cyto-Freeze (Control Company, Houston, Texas) if necessary). The sample is then weighed and divided by the area of ​​the die to obtain the basis weight of the nonwoven web. Results are reported in 0.1 grams per square meter (gsm) as the average of five samples.

[0140] Emtec Test The Emtec test is performed on a portion of the nonwoven web of interest. In this test, TS7, TS750, and D values ​​are measured using an Emtec Tissue Softness Analyzer ("Emtec TSA") (Emtec Electronic GmbH, Leipzig, Germany) connected to a computer running Emtec TSA software (version 3.19 or equivalent). The Emtec TSA includes a rotor with a vertical blade that rotates on the test sample at a defined calibrated rotation speed (set by the manufacturer) and a contact force of 100 mN. Contact between the vertical blade and the test sample creates vibrations in both the blade and the test specimen, and the resulting sound is recorded by a microphone in the instrument. The recorded sound files are then analyzed by the Emtec TSA software to determine the TS7 and TS750 values. The D value is a measure of the stiffness of the sample and is increased from 100 mN to 600 mN based on the vertical distance required for the contact force of the blade on the test sample. Sample preparation, instrument operation, and test procedures are performed according to the instrument manufacturer's specifications.

[0141] Sample preparation Test samples are prepared by cutting square or circular portions of interest from the nonwoven web of the absorbent article. It is desirable not to use a freeze spray to remove the nonwoven web to be analyzed from the absorbent article, but it is acceptable to use a freeze spray on the distal areas to help initiate separation of the layers. The test samples are cut to lengths and widths (diameter for circular samples) of no less than about 90 mm and no more than about 120 mm to ensure that the sample can be properly clamped in the TSA instrument. (If the absorbent article does not accommodate a large enough area of ​​the substrate of interest to extract a sample of the size specified above, it is acceptable to sample an equivalent material from roll stock.) Test samples are selected to avoid very large wrinkles or folds in the test area. Six substantially similar replicate samples are prepared for testing.

[0142] Prior to conducting the TSA test, all samples are equilibrated for at least 2 hours at TAPPI standard temperature and relative humidity conditions (23° C.±2° C. and 50%±2%) and the TSA test is also conducted under TAPPI conditions.

[0143] Test procedure The instrument is calibrated according to Emtec's instructions using a one-point calibration method using appropriate reference standards available from Emtec (so-called "ref. 2 samples" or equivalent).

[0144] The test specimen is mounted in the fixture with the intended surface facing upwards and the test is performed according to the manufacturer's instructions. The software displays the values ​​of TS7, TS750, and D upon completion of the automated fixture test routine. TS7 and TS750 are each within 0.01 dBV. 2 The force is recorded in rms units and D is recorded to the nearest 0.01 mm / N. The test specimen is then removed from the fixture and disposed of. This test procedure is performed separately on the corresponding intended surface (the wearer-facing surface of the topsheet specimen and the garment-facing surface of the outer cover nonwoven material specimen) of each of the six replicate specimens.

[0145] The values ​​of TS7, TS750, and D are each averaged over six sample replicates (arithmetic mean). The average values ​​of TS7 and TS750 are within 0.01 dBV 2 Reported in rms units. Average D is reported to the nearest 0.01 mm / N.

[0146] Measurement method of intensive properties using micro-CT This method for measuring intensive properties by micro-CT measures basis weight, thickness and volume density values ​​within visually distinct areas of a substrate sample. The method is based on the analysis of 3D X-ray sample images obtained with a micro-CT instrument (a suitable instrument is a Scanco μCT 50 available from Scanco Medical AG, Switzerland, or equivalent). The micro-CT instrument is a cone-beam microtomograph with a shielded cabinet. A maintenance-free X-ray tube is used as the source with an adjustable focal spot diameter. The X-ray beam passes through the sample, and a portion of the X-rays is attenuated by the sample. The degree of attenuation correlates with the mass of material through which the X-rays must pass. The transmitted X-rays are continuously incident on a digital detector array, which produces a 2D projection image of the sample. A 3D image of the sample is produced by collecting multiple individual projection images of the rotated sample and then reconstructing these projection images into a single 3D image. The instrument is interfaced with software running on a computer to control the image acquisition and store the raw data. The 3D images are then analyzed using image analysis software (suitable image analysis software is MATLAB available from The Mathworks, Inc., Natick, Mass., or equivalent) to measure the intensive properties of basis weight, thickness, and volume density of regions within the sample.

[0147] Sample preparation: To obtain the sample for measurement, one layer of dry substrate material is laid flat and a circular piece 30 mm in diameter is punched out.

[0148] If the substrate material is a layer of an absorbent article, such as a topsheet, backsheet, outer cover nonwoven material, acquisition layer, distribution layer, or other component layer, the absorbent article is taped to a hard flat surface in a planar configuration. The individual substrate layers are carefully separated from the absorbent article. If necessary, a scalpel and / or a cryo-spray (Cyto-Freeze from Control Company, Houston TX) can be used to remove the substrate layer from further underlying layers to prevent longitudinal and lateral stretching of the material. Once the substrate layer is removed from the article, samples are punched out as described above.

[0149] If the substrate material is in the form of a wet wipe, open a new package of wet wipes and remove the entire stack from the package. Remove one wipe from the middle of the stack, lay it flat and allow it to dry completely before die cutting a sample for analysis.

[0150] Samples can be cut from any location that contains a visually distinct zone for analysis. Within a zone, the area for analysis is the area associated with a three-dimensional feature that defines a microzone. A microzone contains at least two visually distinct areas. A zone, three-dimensional feature, or microzone may be visually distinct due to varying texture, height, or thickness. Areas within different samples taken from the same substrate material may be analyzed and compared to each other. When selecting the location for taking the sample, care should be taken to avoid folds, wrinkles, or tears.

[0151] Acquire images: The microCT instrument is prepared and calibrated according to the manufacturer's specifications. The sample is placed between two rings of low density material with an inner diameter of 25 mm in a suitable holder. This allows the central portion of the sample to be horizontally positioned and scanned without any other material directly adjacent to its top and bottom surfaces. Measurements should be taken in this area. The field of view of the 3D image is approximately 35 mm on each side in the XY plane, has a resolution of approximately 5000 x 5000 pixels, and a sufficient number of 7 micrometer thick slices are collected to completely encompass the Z direction of the sample. The reconstructed 3D image resolution contains 7 micrometer isotropic voxels. Images are acquired using a 45 kVp and 133 μA power supply without additional low energy filters. These current and voltage settings can be optimized to allow enough x-rays to penetrate the sample to maximize contrast in the projection data, but once optimized, are kept constant for all substantially similar samples. A total of 1500 projection images are acquired with an integration time of 1000 ms and 3 averages. These projection images are reconstructed into 3D images and stored in 16-bit RAW format to preserve the complete detector output signal for analysis.

[0152] Image Processing: Load the 3D image into image analysis software. Threshold the 3D image to isolate and remove background signal due to air, but retain the signal from the sample fibers within the substrate.

[0153] Three 2D intensive property images are generated from the thresholded 3D image. The first is a basis weight image. To generate this image, the value of each voxel in the XY slice is summed with all of the corresponding voxel values ​​in the other Z slices that contain signal from the sample. This generates a 2D image where each pixel has a value equal to the cumulative signal throughout the sample.

[0154] A basis weight calibration curve is generated to convert the raw data values ​​in the basis weight image to actual values. A substrate having a substantially similar composition as the sample to be analyzed and a uniform basis weight is obtained. At least 10 replicate samples of the calibration curve substrate are obtained according to the procedure described above. The basis weight of each of the single layer calibration samples is accurately measured by measuring the mass to the nearest 0.0001 g, dividing by the area of ​​the sample, and converting to grams per square meter (gsm), and the average is calculated to the nearest 0.01 gsm. A micro-CT image of the single layer calibration sample substrate is obtained according to the procedure described above. The micro-CT image is processed according to the procedure described above to generate a basis weight image including the raw data values. The actual basis weight value of the sample is the average basis weight value measured on the calibration sample. Two layers of the calibration substrate sample are then stacked on top of each other, and a micro-CT image of the two layers of the calibration substrate is obtained. A raw data image of the combined basis weight of both layers is generated. The actual basis weight value is equal to twice the average basis weight value measured on the calibration sample. The procedure is repeated by stacking single-ply calibration substrates, acquiring micro-CT images of all layers, and generating raw data basis weight images of all layers, whose actual basis weight value is equal to the number of layers multiplied by the average basis weight value measured on the calibration samples. In total, at least four different basis weight calibration images are obtained. To ensure an accurate calibration, the basis weight values ​​of the calibration samples should include values ​​above and below the basis weight value of the original sample being analyzed. A calibration curve is generated by performing a linear regression of the raw data against the actual basis weight values ​​for the four calibration samples. This linear regression should have an R2 value of at least 0.95, otherwise the entire calibration procedure is repeated. This calibration curve is then used to convert the raw data values ​​to actual basis weights.

[0155] The second intensive property 2D image is the thickness image. To generate this image, the top and bottom surfaces of the sample are identified and the distance between these surfaces is calculated to obtain the thickness of the sample. The top surface of the sample is identified by identifying the Z voxel location for every pixel location in the XY plane where the sample signal was first detected, starting with the top Z slice and proceeding through the sample to evaluate each slice. To identify the bottom surface of the sample, the same procedure is followed except that all Z voxels located are the XY plane locations where the sample signal was last detected. Once the top and bottom surfaces are identified, they are smoothed with a 15x15 median filter to remove signal from stray fibers. The 2D thickness image is then generated by counting the number of voxels that lie between the top and bottom surfaces for each pixel location in the XY plane. This raw thickness value is then converted to an actual distance in micrometers by multiplying the number of voxels by the thickness resolution of the 7 μm slice.

[0156] The third intensive property 2D image is the volume density image. To generate this image, the pixel value in each XY plane of the basis weight image in gsm is divided by the corresponding pixel in the thickness image in micrometers. The volume density image has units of grams per cubic centimeter (g / cc).

[0157] Intensive properties of basis weight, thickness, and volume density by micro-CT: The method begins by identifying an area to be analyzed. The area to be analyzed is an area associated with a three-dimensional feature that defines a microzone. A microzone includes at least two visually distinct areas. A zone, three-dimensional feature, or microzone may be visually distinct due to varying texture, height, or thickness. The boundary of the area to be analyzed is then identified. The boundary of the area is identified by visually distinguishing differences in intensive properties compared to other areas in the sample. For example, the boundary of the area can be identified based on visually distinguishing differences in thickness compared to another area of ​​the sample. Any intensive property can be used to distinguish the boundary of the area of ​​the physical sample itself of any of the micro-CT intensive property images. Once the boundary of the area is identified, an oval or circular "region of interest (ROI)" is drawn inside the area. The ROI should have an area of ​​at least 0.1 mm2 and be selected to measure an area having an intensive property value representative of the identified area. The average basis weight, thickness, and volume density within the ROI are calculated from each of the three intensive property images. These values ​​are recorded as the basis weight of the area to the nearest 0.01 gsm, the thickness to the nearest 0.1 micrometer, and the bulk density to the nearest 0.0001 g / cc.
