Description

[Technical Field]

[0001] The present invention relates to a pant-type wearable article having a desirable tactile and aesthetic feel. [Background technology]

[0002] Infants and other individuals with incontinence wear absorbent items such as diapers to receive and contain urine and other bodily waste. Pull-on absorbent items, also known as pant-style absorbent items, are worn by inserting the wearer's legs into the leg openings and sliding the item upwards to fit around the lower torso. Pant-style absorbent items are widely used for toddlers who can walk and are often toilet-trained, as well as for more active toddlers who tend to be more difficult to put on tape-type absorbent items, and for younger toddlers who require a softer fit around the waist and leg openings.

[0003] Pants-type articles can take various forms, having sufficient elasticity around and near the waist opening to facilitate the wearer or caregiver unfolding the article and inserting the wearer's legs into the leg openings to put on the article. The area around and near the waist is often referred to as the elastic belt. One type of pants-type article is a belt-type pant having a central chassis covering the wearer's crotch area and separate elastic belts defining the waist and leg openings, as described in International Publication No. 2006 / 17718(A). Another type of pants-type article is a one-piece pant where the outer cover of the article is configured to completely cover the entire surface of the article facing the clothing, and the portion configured to stretch around the torso is considered the elastic belt area.

[0004] Regardless of the structure of the article, the outer surface of the article or the surface facing clothing is likely to be the most touched and observed by the wearer or caregiver during use, and therefore its characteristics are most relevant to the quality and function of the article. Desirable qualities include an underwear-like appearance and a pleasant tactile feel such as softness and cushioning. An underwear-like appearance can be improved by providing a surface facing clothing with a certain aesthetic sense so that the belt area and crotch area are not easily distinguishable. Desirable functions include secure fit, breathability and comfort, or intuitive signals of such attributes.

[0005] On the other hand, from a manufacturer's perspective, it is desirable to provide high-quality absorbent articles by selecting materials in a way that allows for the best possible user experience relative to the cost of materials, while controlling the manufacturing costs of the articles, and then assembling them.

[0006] [Patent Document 1] International Publication No. 2006 / 17718(A) [Overview of the project] [Problems that the invention aims to solve]

[0007] Based on the foregoing, there is a need for wearable articles that offer improved stretchability for easier application, improved fit to prevent sagging, improved comfort and softness, and improved breathability for skin health. There is also a need for wearable articles with improved aesthetics that intuitively convey the aforementioned functional benefits. Furthermore, there is a need to provide such wearable articles that can be manufactured economically. [Means for solving the problem]

[0008] The present invention relates to a wearable article that is continuous in the longitudinal and transverse directions, comprising a front elastic belt, a rear elastic belt, a crotch region, a waist opening, and a pair of leg openings, wherein the crotch region extends longitudinally between the front elastic belt and the rear elastic belt. Each of the front elastic belt and the rear elastic belt is a laminate including an inner sheet, an outer sheet, and an elastic member extending in the transverse direction, and the front elastic belt and the rear elastic belt are discontinuous with each other in the crotch region. The present invention relates to a wearable article in which the front elastic belt and the rear elastic belt have a transverse dimension LW, the smaller longitudinal dimension of the front elastic belt or the rear elastic belt has a dimension LS, and about 10% to about 40% of LW and about 15% to about 75% of LS, preferably about 30% to about 70%, of which their elastic operability is removed, and the areas in which the elastic operability of the front elastic belt and the rear elastic belt is removed are non-elastic regions 221, the front and rear non-elastic regions 221 have a first belt pattern FBP, and the crotch region has a first crotch pattern FCP.

[0009] In one embodiment, both the first belt pattern FBP and the first crotch pattern FCP are geometric patterns, and both the first belt pattern FBP and the first crotch pattern FCP have a longitudinal orientation according to the measurement method herein.

[0010] In another embodiment, both the first belt pattern FBP and the first crotch pattern FCP are approximately 16 mm 2 ~about 200mm 2 A higher-order pattern HOP having area dimensions is formed, and the first belt pattern FBP and the first crotch pattern FCP are geometric patterns having common elements, and both the first belt pattern FBP and the first crotch pattern FCP have a non-directional orientation according to the measurement method specified herein.

[0012] definition As used herein, the following terms shall have the meanings set forth below.

[0013] "Wearable articles" refer to wearable articles that may take the form of pants, tape-type diapers, incontinence briefs, women's sanitary clothing, etc. "Wearable articles" may be configured to absorb and contain various bodily discharges, such as urine, feces, and menstrual blood. "Wearable articles" may serve as outer covers that are adaptable to be bonded to separable, disposable absorbent inserts for providing absorption and containment functions, such as those disclosed in International Publication No. 2011 / 087503(A).

[0014] "Pants" refers to disposable absorbent garments with pre-formed waist and leg openings. Pants can be worn by inserting the wearer's legs into the leg openings and sliding the pants to fit around the wearer's lower torso. Pants are also commonly referred to as "closed diapers," "pre-fastened diapers," "pull-on diapers," "training pants," and "diaper pants."

[0015] "Longitudinal direction" refers to the direction that extends substantially perpendicularly from one waist edge of an article to the opposite waist edge, and generally parallel to the article's maximum straight-line dimension.

[0016] "Transverse direction" refers to the direction perpendicular to the longitudinal direction.

[0017] "Proximal" and "distal" refer to positions closer to or further away from the longitudinal center of an object, respectively.

[0018] "Body-facing" and "clothing-facing" refer to the relative position of an element, its surface, or a group of elements, respectively. "Body-facing" means that the element or surface is closer to the wearer during wear than any other element or surface. "Clothing-facing" means that the element or surface is further away from the wearer during wear than any other element or surface (i.e., the element or surface is closer to the wearer's clothing that may be worn over a disposable absorbent article).

[0019] "To be positioned" refers to an element being placed in a specific location or position.

[0020] "Joined" refers to a configuration in which one element is directly attached to another element by directly attaching it to that element, and a configuration in which an element is attached to an intermediate member(s), and that intermediate member(s) are further attached to another element, thereby indirectly attaching that element to another element.

[0021] A "film" refers to a sheet-like material in which the length and width of the material significantly exceed its thickness. Typically, a film has a thickness of approximately 0.5 mm or less.

[0022] "Water permeability" and "impermeability" refer to the permeability of a material under the intended use conditions of a disposable absorbent article. Specifically, the term "water permeability" refers to a layer or layer structure having pores, openings, and / or interconnected voids through which liquid water, urine, or synthetic urine can pass through the thickness of the layer or layer structure in the absence of compressive pressure. Conversely, the term "impermeability" refers to a layer or layer structure through which liquid water, urine, or synthetic urine cannot pass through the thickness of the layer or layer structure in the absence of compressive pressure (other than natural forces such as gravity). An impermeable layer or layer structure according to this definition may be permeable to water vapor, i.e., it may be "vapor permeable."

[0023] "Stretchable" and "stretchable" mean that the width or length of a component in a relaxed state can be stretched or increased.

[0024] "Stretchable" or "made stretchable" means that the components include at least one part made from an elastic material.

[0025] The terms "stretchable material," "extendable material," or "stretchable material" are used interchangeably and refer to a material that, when a biasing force is applied, can be stretched to an elongated length of at least approximately 110% of its original relaxed length (i.e., stretched 10% longer than its original length) without bursting or fracturing (as measured by EDANA method 20.2-89), and when the applied force is removed, exhibits a slight recovery of less than approximately 20% of its elongation without completely bursting or fracturing. If such an stretchable material recovers at least 40% of its elongation when the applied force is released, that stretchable material is considered "elastic" or "elastomerous." For example, an elastic material with an initial length of 100 mm can be stretched to at least 150 mm and, when the force is removed, contracts to at least 130 mm (i.e., exhibits a 40% recovery). If, upon release of the applied force, the material's recovery is less than 40% of its elongation, the stretchable material is considered "substantially inelastic" or "substantially non-elastomerous." For example, a stretchable material with an initial length of 100 mm can be stretched to at least 150 mm and, upon removal of the force, will contract to at least 145 mm (i.e., exhibiting a 10% recovery).

[0026] The "dimensions," "length," "width," "pitch," "diameter," "aspect ratio," "angle," and "area" of an article are all measured using a ruler or magnifying glass while the article is stretched to its fully elongated circumference W1, in accordance with the "total article force measurement method" as specified herein.

[0027] "Artwork" means a visual representation to the naked eye that is provided by printing or other means and has color. Printing includes various methods and apparatus well known to those skilled in the art, such as lithography, screen printing, flexographic printing, and gravure inkjet printing techniques.

[0028] In this specification, the terms “color” or “coloring” may include any primary color other than white, namely black, red, blue, purple, orange, yellow, green, and indigo, as well as any light or mixed colors thereof. White is defined as CIE L * a * b * According to the color system, at least 94 L * a value equal to 0 ± 2 * The value, and b equal to 0 ± 2 * It is defined as a color that has a value. [Modes for carrying out the invention]

[0029] Figure 1A is a perspective view of the wearable article (20) of the present invention, Figure 1B is a schematic diagram showing the front side of the wearable article of the present invention in a contracted state, and Figure 2A is a schematic plan view of the wearable article in a flat, non-contracted state, showing the side facing the garment and where the seams are not joined. The wearable article (20) has a longitudinal center line LX which also serves as the longitudinal axis, and a transverse center line TX which also serves as the transverse axis. The wearable article (20) has a side facing the body, a side facing the garment, a front elastic belt (84), a rear elastic belt (86), a crotch area (30), and a side seam (32) that joins the front elastic belt (84) and the rear elastic belt (86) to form two leg openings and a waist opening.

[0030] The wearable article (20) may be a belt-type pant as shown in Figures 1A, 1B, 2A, and 2B, comprising a central chassis 38 covering the wearer's crotch area (30), a front elastic belt (84), and a rear elastic belt (86) (hereinafter referred to as "front and rear elastic belts"), wherein the front and rear elastic belts (84, 86) form a separate annular elastic belt (40) that extends transversely and defines the waist opening. In the case of belt-type pant, the separate annular elastic belt (40) may also be referred to as the elastic belt (40). In belt-type pant as shown in Figures 1A, 1B, and 2A, the front and rear elastic belts (84, 86) and the central chassis (38) are joined together to define the leg opening. In the case of belt-type pants, the front elastic belt 84 is the front region (26), the rear elastic belt (86) is the rear region (28), and the remainder is the crotch region (30). Although not shown, the wearable article (20) may be a one-piece pant configured such that the outer cover of the central chassis (38) and the elastic belt (40) are common. In the case of one-piece pants, the portions extending transversely between the side seams (32) are considered to be the front region (26) and the rear region (28), respectively, and the remainder is the crotch region (30). In the case of one-piece pants, the front region (26) is considered to be the front elastic belt (84), and the rear region (28) is considered to be the rear elastic belt (86).

[0031] The central chassis (38) may include a top sheet, a back sheet, an absorbent core (62) positioned between the top sheet and the back sheet, and an outer cover layer (42) for covering the side of the back sheet facing clothing. The top sheet may be a permeable substrate. The back sheet may be an impermeable film. The outer cover layer (42) may be a nonwoven fabric sheet. The central chassis (38) may accommodate an absorbent core (62) positioned on the central chassis (38) for absorbing and containing bodily waste, and an absorbent material-free region (61) surrounding the absorbent core (62). The absorbent material-free region (61) may be made from the top sheet and / or the back sheet and / or the outer cover layer (42) and / or other parts constituting the central chassis (38). In the embodiment shown in Figure 2A, the central chassis (38) has a generally rectangular shape with side edges (48) extending in the left-right longitudinal direction and end edges (50) extending in the front-rear transverse direction. The absorbent core (62) may be present throughout the entire longitudinal dimension of the crotch area and extending at least partially in the front area (26), or at least partially in both the front and rear areas (26, 28). The central chassis (38) may have a front waist panel (52) located in the front area (26) of the absorbent article (20), a rear waist panel (54) located in the rear area (28), and a crotch panel (56) in the crotch area (30) between the front and rear waist panels (52, 54). The center of the front elastic belt (84) is joined to the front waist panel (52) of the central chassis (38), and the center of the rear elastic belt (86) is joined to the rear waist panel (54) of the central chassis (38). The front and rear elastic belts (84, 86) each have a left side panel and a right side panel (82) that do not overlap with the central chassis (38). The central chassis has a crotch panel (56) located between the front waist panel (52) and the rear waist panel (54).

[0032] The absorbent core (62) may include an absorbent layer and a trapping layer. The absorbent layer is a region containing an absorbent material with high retention capacity, such as a superabsorbent polymer. The absorbent layer may not substantially contain cellulose. The superabsorbent polymer in the absorbent layer may be located between a first material layer and a second material layer, which are immobilized by a fibrous layer of thermoplastic adhesive material. The first and second material layers may be nonwoven fiber webs containing synthetic fibers such as single-component fibers of PE, PET, and PP, side-by-side, core / sheath, or island-in-the-sea type fibers. Such synthetic fibers may be formed via a spunbond process or a melt-blown process. A trapping layer may be located between the top sheet and the absorbent layer to facilitate the capture and distribution of bodily waste. The trapping layer may contain cellulose fibers.

[0033] Multiple absorbent layers may be arranged on the absorbent core (62). Parts of the absorbent layers may be configured to substantially lack absorbent material to form channels or multiple channels. The channels may be useful in allowing the absorbent core (62) to bend as it swells with the fluid, so that the absorbent article conforms to the wearer's body after inflation and prevents the article from sagging. Channels may also be formed within the trapping layer and may be configured to at least partially coincide with the channels of the absorbent layer in the thickness direction.

[0034] The elastic belt (40) of the article of the present invention dynamically generates a fitting force and acts to distribute the force that dynamically arises during wear. The front and rear elastic belts (84, 86) can be joined to each other only at the side edges (89) to form a side seam (32), a waist opening and two leg openings. Each leg opening may have elasticity around the leg opening. The elasticity around the leg openings can be provided by a combination of elasticity from the front elastic belt (84), the rear elastic belt (86), and the central chassis (38).

[0035] Referring to Figure 2B, the longitudinal lengths of the backsheet and the outer cover layer (42) may be the same or different. For example, the outer cover layer (42) may be shorter than the length of the backsheet, such that the outer cover layer (42) does not overlap with the elastic belt (40) where the central chassis (38) is located. Such a configuration may allow the elastic belt to have better breathability. Furthermore, such a configuration may provide cost savings. Moreover, such a configuration can prevent interference between the elastic belt (40) and the pattern provided on the non-elastic region (221) of the crotch region (30), as will be described in more detail below. The transverse widths of the backsheet and the outer cover layer (42) may be the same or different. For example, the backsheet may have a transverse width shorter than the transverse width of the outer cover layer (42). Such a configuration may allow the longitudinal side edges (48) of the crotch panel (56), which forms part of the leg opening, to have better breathability. Furthermore, such a configuration may provide cost savings.

[0036] The front elastic belt (84) and the rear elastic belt (86) are configured to impart elasticity to the belt (40). Referring to Figures 1B, 2A, and 2B, the front elastic belt (84) and the rear elastic belt (86) can each be formed by a laminate including a plurality of transversely extending elastic bodies (96), an inner sheet (94), an outer sheet (92), and an outer sheet folding portion (93), where the outer sheet folding portion is an extended portion of the outer sheet material formed by folding the outer sheet material at the distal edges (88) of the front and rear elastic belts, and the belt elastic bodies (96) are sandwiched between these two sheets. The front elastic belt (84) and the rear elastic belt (86) may each be made only of the elastic bodies (96), the inner sheet (94), the outer sheet (92), and the outer sheet folding portion (93). The various patterns discussed below can be provided on the outer sheet (92). The belt elastic members (96) extend transversely, and when the front elastic belt (84) and the rear elastic belt (86) are joined, an annular elastic belt (40) can be provided. At least some of the elastic members (96) extend transversely substantially parallel to each other. All of the elastic members (96) may extend transversely substantially parallel to each other. Such articles can be manufactured economically. The front and rear elastic belts (84, 86) may each have a proximal and distal edge that are continuous transversely, with the proximal edge (90) positioned closer to the longitudinal center of the article than the distal edge (88). The elastic members (96) may be positioned between the front and rear elastic belts (84, 86) and at different longitudinal positions of the belt with the same or different denier, spacing, and force.

[0037] Referring to Figure 2A, the transverse width LW of the uncontracted rear elastic belt (86) is the same as the transverse width of the front elastic belt (84) in the same state. Along the entire width LW, the rear elastic belt (86) between the rear distal edge (88) and the rear proximal edge (90) has a longitudinal dimension LB, and the front elastic belt (84) between the front distal edge (88) and the front proximal edge (90) has a longitudinal dimension LF. LB and LF may be the same or different. The shorter of LB and LF is defined as LS.

[0038] Referring to Figure 2A, LB may be larger than LF. In such a configuration, when the wearable article is assembled to form the waist and leg openings, the wearable article (20) is folded along the transverse centerline TX such that the anterior distal edge (88) aligns with the posterior distal edge (88). The anterior side edge (89) is also aligned with a portion of the posterior side edge (89). The anterior elastic belt (84) and the posterior elastic belt (86) are then joined at the anterior and posterior side edges (89) by a seam (32). However, the anterior and posterior proximal edges (90) do not need to be aligned with each other. The rear proximal edge (90) may be positioned closer longitudinally to the transverse centerline TX than the front proximal edge (90) such that the proximal portion of the rear side panel (82) extends beyond the front proximal edge (90) toward the crotch panel (56) of the central chassis (38). The side edge of the proximal portion of the rear side panel (82) may not be joined or attached anywhere. Thus, the proximal portion of the rear side panel (82) provides a buttock cover (95) as shown in Figure 1B.

[0039] Referring to Figures 1B and 2A, the front and rear elastic belts (84, 86) are treated to remove their elastic mobility from certain areas to form an inelastic region (221). In each of the front and rear elastic belts (84, 86), approximately 10% to 40% of the LW and approximately 15% to 75% of the LS, or approximately 30% to 70% of the LS, have had their elastic mobility removed. The inelastic region (221) may overlap with the front and / or rear waist panels (52, 54) of the central chassis (38). If the central chassis (38) includes an absorbent core (62), the elasticity of the front and / or rear regions overlapping the absorbent core (62) may cause the absorbent layers or any of the layers of the absorbent core (62) to bundle, which may interfere with the tight fit of the central chassis (38) to the wearer. Therefore, it may be advantageous to remove the elasticity from certain regions where the front and / or rear lumbar panels (52, 54) overlap.

[0040] The remainders of the front elastic belt (84) and the rear elastic belt (86) each include an elastic region, the elastic region extending transversely at least along the waist opening to provide a circumferential elastic region. The circumferential elastic region along the waist opening defines the upper gathered region (220).

[0041] Referring to Figure 3A, the laminate can be manufactured by joining an elastic member (96) to at least one of the inner sheet (94) and the outer sheet (92) via a combination of an elastic connector (230) and a vertical connector (234). In Figure 3A, the front elastic belt (84) is shown together with the elastic member (96) and the elastic connector (230), which is represented by a solid line. In Figure 3A, the vertical connector (234) is shown only on the right side of the front elastic belt (84), and the side seam (32) is shown in an unbonded state.

[0042] In this specification, the elastic joint (230) refers to a joint that connects the elastic member (96) along the side edges (89) of the front and rear elastic belts (84, 86). The elastic joint (230) may be applied continuously to each elastic member (96) in the tensile direction adjacent to the side edges (89) of the front and rear elastic belts (84, 86) for a length of at least about 10 mm, or about 10 mm to about 60 mm, including the length designed for the side seam. The elastic joint (230) is provided to provide a relatively strong bond to the elastic member (96) and thus to firmly fix the elastic member (96) within the laminate. Fixation may be assisted by the side seam. A certain proportion or a higher proportion of the dimensions of the elastic joint (230) along the side edges (89) may be joined together. The elastic joint can also be used in an effective process to deactivate the limited transverse dimensions of the elastic member (96). Referring to Figures 2A and 3A, the elastic member (96) may be deactivated in the portion overlapping with the absorbent core (62). In addition to the lateral edge region, elastic couplings (230T) may be provided on both sides of a certain transverse dimension of the elastic member (96), which are designed to be deactivated, and the portion of the elastic member between the elastic couplings (230T) is cut and deactivated. The deactivated portion of the elastic member is not shown. Such deactivation may be referred to herein as a belly cut, and the deactivated region may coincide with the inelastic region (221).

[0043] In this specification, the vertical joint (234) is a joint applied transversely spaced to at least one of the inner sheet (94) and the outer sheet (92) to intermittently join the inner sheet (94) and the outer sheet (92). The vertical joint (234) can also join the elastic member (96) to at least one of the inner sheet (94) and the outer sheet (92). The vertical joint (234) may be provided only on the outer sheet (92). Referring to Figure 3A, the vertical joint (234) may be provided in a pattern over the entire area of ​​the laminate. By providing the vertical joint (234) in a pattern over the entire area of ​​the laminate, the vertical joint (234) can function as a joint between the inner and outer sheets (92, 94) in the area where the elastic member (96) is cut. The vertical coupling portion (234) may be provided in a region adjacent to the side edge portion (89), and therefore in an overlapping region where the elastic coupling portion (230) is provided. Alternatively, the vertical coupling portion (234) may be provided only in regions where the elastic coupling portion (230) is not provided. The vertical coupling portion (234) may be provided at least in regions where the elastic member (96) is operably elastic and where the elastic coupling portion (230) is not present.

[0044] Referring to Figure 4A, the vertical joint (234) is observed in the thickness direction of the laminate along a single elastic member (96) in a transversely extended state, where Figure 4A shows only the outer sheet (92), the vertical joint (234), and the elastic member (96), and the vertical joint (234) is provided on the outer sheet (92). The vertical joint (234) may have a transverse dimension VG2 and is provided as a continuous pattern aligned in the longitudinal direction, where each longitudinal pattern of the vertical joint (234) is spaced apart from each other by a transverse pitch VG1, where VG1 may be about 2 mm to about 15 mm and VG2 may be about 0.2 mm to about 7 mm. Focusing on a single elastic member (96), the vertical connector (234) can provide intermittent connections between the elastic member (96) and one of the inner sheet (94) and the outer sheet (92), or between the elastic member (96) and the outer sheet (92). This is in contrast to elastic connectors (230) that are provided continuously along a certain length in the stretching direction of the elastic member (96). Therefore, in regions where the elastic member (96) is intermittently connected to one of the inner sheet (94) and the outer sheet (92), the portion of the elastic member (96) between the transverse vertical connectors (234) is not attached to any other portion of the laminate. In Figure 4A, the elastic member (96) is connected to the outer sheet (92). Referring to Figure 4B, when the elastic member (96) contracts, this causes the unattached portion of the outer sheet (92) to fold away from the elastic member (96), resulting in the formation of gathers. Therefore, compared to the area to which the elastic bonding portion (230) is applied, the outer sheet (92) has fewer limitations in the creation of gathers.

[0045] While not bound by theory, it is believed that the inner sheet (94) and outer sheet (92) having less restriction on the elastic member (96) contributes to the creation of improved regularity of gathers, and in this respect, a significant amount of inner and outer sheet material (92, 94) present between the vertical joints (234) can be used to create longitudinally continuous gathers. While not bound by theory, it is also believed that the inner and outer sheet material (92, 94) having less restriction on the elastic member (96) improves the extensibility of the elastic member (96) and provides ease of application. Compared to an elastic belt made only of elastic joints (230) in which all of the elastic member (96) are continuously connected, the elastic belt (40) of the present invention may have a lower perimeter force when stretched, according to the measurement method herein. Furthermore, despite such a relatively low perimeter force when stretched, the elastic belt (40) of the present invention can maintain a suitable perimeter force when fitted, according to the measurement method herein. While not bound by theory, it is also considered that the overall breathability of the laminate can be improved and skin health can be enhanced by having the inner and outer sheet materials (92, 94) have less restriction on the elastic member (96). While not bound by theory, it is also considered that the vertical joint (234) provides a configuration in which, when the elastic belt (40) contracts, a higher proportion of the inner and outer sheet materials (92, 94) are available to form the outer surface of the laminate, while the elastic member (96) remains located within the thickness of the laminate. As a result, the laminate is provided with improved elasticity and thickness, and therefore provides improved comfort and softness when worn. Furthermore, while not bound by theory, when the elastic belt (40) contracts, the body-facing surface of the elastic belt (40) is provided with higher longitudinal rigidity in that a higher proportion of the inner and outer sheet materials (92, 94) are available to form the outer surface of the laminate with greater regularity, and therefore contributes to an improved fit to prevent sagging. Furthermore, when the elastic belt (40) contracts, the elastic material becomes less visible, further improving the aesthetically pleasing regularity of the gathers.

[0046] In order to make a significant amount of the inner and outer sheet material (92, 94) between the vertical joints (234) available for gathering in the transverse direction, VG1 may be about 2 to 20 times, or about 3.5 to 10 times, VG2.

[0047] Any method known in the art may be used for bonding, such as hot-melt bonding, thermal energy, and ultrasonic energy. The bond strength can be adjusted by the area of ​​the bond or by the different bonding or energy levels provided by the bond, for example, by adjusting the amount and strength of the adhesive. The bond strength of the elastic bond (230) and the vertical bond (234) may be the same or different. The elastic bond (230) and the vertical bond (234) may be provided by the same hot-melt bonding.

[0048] The vertical joints (234) may be continuous lines extending in the longitudinal direction. Referring to Figure 3B, the vertical joints (234) may be a row of separate joints aligned in the longitudinal direction. Each separate vertical joint (234) may have a longitudinal dimension of about 0.5 mm to about 10 mm and a longitudinal pitch of about 1 mm to about 10 mm, or about 0.8 mm to about 5 mm. By providing the vertical joints (234) as a row of separate joints, the overall area of ​​the joints can be reduced. This is advantageous in maintaining a soft feel of the laminate by allowing the joints between the inner and outer sheet materials (92, 94) to be more rigid. Furthermore, this can save material or energy for joining. Each separate vertical joint (234) may be provided at an appropriate longitudinal pitch such that there is at least one separate joint joining each elastic member (96), but this is not required. Rather, it is essential that at least one separate vertical coupling portion (234) is spaced apart in each longitudinal direction of the elastic members (96) so that adjacent elastic members (96) do not come into contact with each other. As long as at least one separate vertical coupling portion (234) is spaced apart in each longitudinal direction on the elastic members (96), the elastic coupling portion (230) prevents the elastic members (96) from moving away from their intended position by providing a firm bond of the elastic members (96) along the side seams and the outer circumference of the non-elastic region (221). In the entire front elastic belt (84) or the entire rear elastic belt (86), there may be no elastic members (96) bonded to the inner sheet (94) or outer sheet (92) by a separate vertical coupling portion (234). In the entire front elastic belt (84) or the entire rear elastic belt (86), at least 1 to about 50% of the elastic members (96) may be coupled to the inner sheet (94) or outer sheet (92) by separate vertical couplings (234). In the individual elastic members (96) along the actuated length, some portions may be coupled by separate vertical couplings (234), while some portions may remain uncoupled by separate vertical couplings (234).

[0049] Referring to Figure 2A, the belt-type pants can be provided with end seals on the proximal edges (90) of the front and rear elastic belts (84, 86) to keep the inner and outer sheets (92, 94) closed at the proximal edges (90), thus preventing the elastic members (96) from making contact. Such non-contact capability of the elastic members (96) may be particularly advantageous when the article is for a young wearer. Alternatively or in addition, the elastic member (96) located closest to the proximal edge (90) may be provided with a joint that is operationally elastic along the transverse dimension of the elastic member (96).

[0050] Referring to Figure 2A, the elastic member (96) may be made of a plurality of elastic strands (96) extending parallel to each other in the transverse direction, and the laminate has at least a region in which the elastic strands (96) have a longitudinal pitch of about 2 mm to about 20 mm, or about 3 mm to about 12 mm, or about 3 mm to about 7 mm. At least a portion of the upper gathered region (220) may have elastic strands (96) arranged at a longitudinal pitch of about 3 mm to about 7 mm. Although not bound by theory, such a longitudinal pitch of elastic strands (96) combined with the transverse pitch of the vertical joint (234) as described above is thought to contribute to the creation of improved regularity of gathers by providing appropriate longitudinal continuity of the material provided by the stiffness of the inner and outer sheet materials (92, 94). At least a portion of the upper gathered region (220) may have elastic strands (96) arranged at a constant longitudinal pitch, where the pitch is approximately 2 mm to 20 mm, or approximately 3 mm to 12 mm, or approximately 3 mm to 7 mm, with a deviation of approximately 1.5 mm or less. Although not bound by theory, such a constant pitch of elastic strands (96) is thought to contribute to the creation of gathers with improved regularity and continuity.

[0051] The front and rear elastic belts (84, 86) can be manufactured by connecting continuous inner and outer sheet material and continuous elastic strands extending along the transverse axis of the article via elastic connectors (230) and vertical connectors (234). During manufacturing, the continuous inner and outer sheet material and continuous elastic strands may be transported in the machine direction, and the machine direction of manufacturing coincides with the transverse axis TX of the article. In such a manufacturing process, the vertical connectors (234) are aligned continuously or separately across the machine direction and are spaced intermittently apart by a pitch of VG1 in the machine direction of manufacturing. The longitudinal pattern of the vertical connectors (234) may be across the machine direction of manufacturing, i.e., coincide with the longitudinal axis LX of the article, or may be slightly inclined for better control of the process, especially if the vertical connectors (234) are provided by applying the connectors with rotating rollers. The vertical joint (234) may be tilted across the machine direction of manufacture, i.e., from the longitudinal axis LX of the article, at an angle of about 0.1 to about 30 degrees in either a clockwise or counterclockwise direction, or at an angle of about 0.1 to about 15 degrees in either a clockwise or counterclockwise direction.

[0052] The overall tensile stress (N / m) of the front and rear elastic belts (84, 86) can be profiled to maintain a certain force during wear, preventing the article from sagging after being loaded, while providing the functional benefits of the present invention, such as ease of stretching and application. If the elasticity of the front and rear elastic belts (84, 86) is provided by a plurality of elastic members (96) extending transversely, the tensile stress can be adjusted by one or more of the following methods: 1) the elongation ratio of the elastic members (96), 2) the density (dtex) of the elastic members (96), 3) the longitudinal spacing of the plurality of elastic members (96), and 4) the effective length of the elasticity of the elastic members (96) in the transverse direction. With respect to the elongation ratio, "0% elongation ratio" means the original length of the elastic member. If a portion of the elastic member (96) has had its elasticity removed, the remaining portion of the unaffected elastic member that is capable of imparting elasticity is defined as the "effective length of the elasticity of the elastic member."

[0053] Referring to Figure 2A, the anterior and posterior elastic belts (26, 28) can each be divided into four zones extending transversely, which can be defined by their position from the distal edge (88) to the proximal edge (90) relative to the ratio of the seam length LS. In the example in Figure 2A, the entire length of the belt side edge (89) of the anterior region (26) is the anterior elastic belt (84), which is joined with a certain length of the belt side edge (89) of the posterior region (28), and this is the posterior elastic belt (86) that defines the seam length LS. If the seam length LS is considered to be 0% at the distal edge (88) and 100% at the proximal edge (90) of the side seam (32), the zones are defined as follows: 0-25% as the lumbar zone (102), 25-50% as the distal abdominal zone (104), 50-85% as the proximal abdominal zone (106), and 85-100% as the leg zone (108), and so on. If there is an elastic member located 25% from the distal edge 88, such an elastic member is considered to be included in the lumbar zone (102). If there is an elastic member located 50% from the distal edge (88) or 85% from the distal edge (88), such an elastic member is considered to be included in the proximal abdominal zone (106).

[0054] In the article of the present invention, the tensile stress in the anterior proximal abdominal zone (106) may be higher than the tensile stress in any of the anterior lumbar zone (102), anterior distal abdominal zone (104), or anterior leg zone (108). The tensile stress in the anterior proximal abdominal zone (106) can be greater than the tensile stress in any other zone, either anterior or posterior. The tensile stress in the posterior distal abdominal zone (104) may be higher than the tensile stress in any of the posterior lumbar zone (102), posterior proximal abdominal zone (106), or posterior leg zone (108). Comparing the four zones of each of the anterior and posterior elastic belts, the tensile stress may be highest in the anterior proximal abdominal zone (106), followed by the posterior distal abdominal zone (104). While not bound by theory, such zone-specific profiling regarding tensile stress is thought to provide the article of the present invention with an elastic belt (40) shaped to conform well to the human body, particularly the lower torso of an infant under 36 months of age, and thus provide the wearer with good fit and comfort without compromising anti-sagging or anti-leakage. That is, the anterior proximal abdominal zone (106) is subjected to high tensile stress so that the article can accommodate the wearer's buttocks while securing the article to the wearer's trochanter, leaving more area in the posterior proximal abdominal zone (106). The upper gathered region (220) may be provided with relatively low tensile stress, as long as the article is securely secured at the trochanter. While not bound by theory, such relatively low tensile stress is thought to contribute to improved regularity of the gathers and to providing the upper gathered region (220) with a softer fit.

[0055] In this invention, at least one of the inner sheet (92) and the outer sheet (94) may further include a plurality of deformations, the deformations being longitudinally aligned. The deformations may be holes, slits, markings, embossings, protrusions, or any other permanent deformations into the nonwoven material for producing the inner sheet (92) and / or the outer sheet (94), as long as they are longitudinally aligned. For example, referring to Figure 5A, the deformations on the outer sheet (92) are represented in the form of holes. Each longitudinal deformation pattern may be spaced apart from one another by a transverse pitch of DF1, such that VG1 is greater than DF1, or VG1 is at least about 1.5 times or at least about 2 times DF1. Although not bound by theory, such deformations provided in relation to vertical joints (234) assist the nonwoven material in folding the inner sheet (92) and / or the outer sheet (94) within dimension VG1, and in producing the folds continuously in the longitudinal direction. Therefore, the regularity of the gathers is improved. The longitudinal deformation pattern may or may not coincide with the longitudinal pattern of the vertical joint (234). In fact, the discovery of the present invention is that even when the longitudinal deformation pattern does not coincide with the longitudinal pattern of the vertical joint (234), the regularity of the gathers is further improved. If the longitudinal deformation pattern and the longitudinal pattern of the vertical joint (234) are to coincide, process precision may be required, and such coincidence may be omitted. Even when the longitudinal deformation pattern does not coincide with the longitudinal pattern of the vertical joint (234), by providing DF1 and VG1 in a relationship other than multiple integers, most of the longitudinal deformation pattern fits within the longitudinal pattern of the vertical joint (234), assisting in gather formation.

[0056] The deformable portion may be a continuous line extending in the longitudinal direction, or a row of separate deformable portions aligned in the longitudinal direction and spaced apart from each other by the longitudinal pitch of DF2, where DF2 is less than or equal to DF1 as shown in Figure 5A. By providing the deformable portion in a row of separate deformable portions, the overall area weakened or stiffened by the deformable portion can be reduced. By making DF2 the same as or smaller than DF1, the longitudinal folding of the inner and outer sheet materials (92, 94) is facilitated as described above.

[0057] The deformation portion may be a hole on the outer sheet, the hole being circular, elliptical, or polyhedral in shape, having a minor radius of at least about 0.1 mm, or about 0.1 mm to about 1.5 mm, or about 0.4 mm to about 1.5 mm, and having an aspect ratio of less than about 3, or less than about 2. In this specification, the minor radius means half of the radius of a circle, the minor radius of an ellipse, or the shortest dimension of a polyhedron. Holes of such size and shape can be visible to the naked eye on the surface facing the garment, thus contributing to the breathability and high quality of the gathers and the entire laminate. Therefore, the holes may be provided on the outer sheet (92). Holes may be provided on both the inner and outer sheets (92, 94) to improve breathability. Furthermore, by providing a VG1 larger than DF1, the holes are positioned on the folded portion as described above, thus improving the visibility of the holes even when the gathers are in a contracted state. Figure 5B is a plan view of the elastic belt of the present invention in an extended state, while Figure 5C is the same elastic belt in a contracted state. In the elastic belts of Figures 5B and 5C, VG1 is approximately 1.5 times DF1. As can be seen in Figure 5C, by providing such a relationship between VG1 and DF1, at least one row of holes in the longitudinal direction is continuously folded in a longitudinal manner, providing continuous gathers in the longitudinal direction, with the holes located near the peaks of each gather. This improves the visibility of the holes. This can further improve breathability and the sense of breathability.

[0058] The front and rear inelastic regions (221) are de-elastic, with little to no gathering, and therefore the material forming the garment-facing side of the inelastic regions (221) has high visibility. Furthermore, the front and rear inelastic regions (221) are adjacent to the upper gathered region (220) and the crotch region (30), and when worn, are positioned approximately in the center of the article in both its longitudinal and transverse directions. Thus, the aesthetic effect of the inelastic regions (221) in harmony with the rest of the article provides a certain sense of the overall quality of the article. The aesthetic effect of the inelastic regions (221), in harmony with the upper gathered region (220), can improve the directionality of the longitudinally continuous gathering of the upper gathered region (220). In addition or alternatively, the aesthetic effect of the inelastic regions (221), in harmony with the crotch region (30), can improve the integrated, underwear-like appearance of the article. Such aesthetic effects are expected to provide a sense of high quality.

[0059] The inelastic region (221) and the crotch region (30) are provided with an aesthetic or geometric pattern. In this invention, an aesthetic pattern means a repeating visual presentation which may be a geometric pattern or a printed pattern, insofar as the repeating visual presentation is visible to the naked eye from the garment-facing side. In this invention, a geometric pattern means a permanent deformation in the material forming the garment-facing side of the inelastic region (221) which is a repeating visual presentation visible to the naked eye from the garment-facing side. The permanent deformation may be a hole, emboss, or other textured deformation provided on the garment-facing side of the article. The garment-facing side of the crotch region (30) may be the outer cover layer (42). Permanent deformations which are not visible to the naked eye are not considered geometric patterns in this specification. Permanent deformations that are not visible to the naked eye include those that are too fine or too minute to be perceived by the naked eye, those that are provided with such uniformity that the deformations cannot be perceived, and those that are not located on the surface facing the garment. Permanent deformations may be the same as or different from those described above in order to assist in gathering. The printed pattern may be printed in color directly on the garment-facing surface of the inelastic region (221) or the crotch region (30), and / or printed on a layer overlapping the inelastic region (221) or the crotch region (30) and visible through the overlapping layer. For example, the printed pattern may be provided on the garment-facing surface of the inner sheet (94). For example, the printed pattern may be provided on a layer of the central chassis that overlaps with the inelastic region (221) or the crotch region (30).

[0060] The inelastic region (221) of this specification is provided with a first belt pattern FBP. The first belt pattern may have a longitudinal orientation according to the measurement method specified herein. The longitudinal orientation can be measured by observation. Alternatively or in addition, the longitudinal orientation may be determined by image analysis, and the first belt pattern FBP may have a longitudinal dispersion of at least about 35%, or at least about 50%, or at least about 70%, and a transverse dispersion of about 35% or less, or about 20% or less, or about 10% or less, according to the measurement method specified herein. The longitudinal orientation described herein is the impression of being oriented longitudinally to the naked eye when observing a repeated visual presentation of the pattern. Referring, for example, to Figures 6A and 6B, the article of the present invention is shown in a contracted state observed from the front. The inelastic region (221) of the front elastic belt is provided with holes in the first belt pattern FBP that are visible from the side facing the garment. The holes are aligned in roughly straight lines that extend in the longitudinal direction, and each of these lines is repeated transversely at intervals. Such lines may be spaced apart from each other with a transverse pitch DF1 of approximately 2 mm to 15 mm. The first belt pattern FBP in Figures 6A and 6B has a longitudinal orientation.

[0061] Referring to Figures 11A to 11D, the specific meaning of the longitudinal orientation measured by observation is explained. First, the base unit, which is the smallest complete unit of repeating deformations or prints to create a pattern, is identified. The pattern may be a regular and continuous repeating pattern of deformations or prints with consistent spacing that does not have a specific boundary of the pattern in both the longitudinal and transverse directions. Such a regular and continuous repeating pattern with consistent spacing is called a random repeating pattern. The base unit of a random repeating pattern is defined as a group of at least three or at least four individual deformations or prints that can enclose a specific area defined as the base unit area. For example, Figure 11A is a random repeating pattern with a base unit consisting of four deformations, each deformation having a circular shape that may be a hole, and the base unit area is approximately rectangular. In another example, Figure 11B is a random repeating pattern with a base unit consisting of four deformations, each deformation having a bar shape that may be an emboss, and the base unit area is approximately diamond-shaped. In yet another example, Figure 11C shows a random repeating pattern having a basic unit consisting of four deformations, each deformation having an S-shape which may be a slit, and the basic unit area is approximately diamond-shaped. In yet another example, Figure 11D shows a random repeating pattern having a basic unit consisting of approximately 50 deformations which are two sine waves side by side, each deformation having a circular shape which may be a hole, and the basic unit area is approximately corrugated with substantially constant transverse dimensions. Within the basic unit, identify the nearest adjacent deformations or prints in the longitudinal and transverse directions and measure their spacing. Patterns with an X-spacing that is at least 10% longer than the Y-spacing are considered to have longitudinal orientation. Patterns with an X-spacing that is less than 110% of the Y-spacing are considered not to have longitudinal orientation.

[0062] Longitudinal orientation can be determined by image analysis, as will be discussed in more detail in the following measurement section. Longitudinal / transverse dispersion is used to extract a continuous impression of the pattern in both the longitudinal and transverse directions by utilizing image analysis to define the dispersion of a particular pattern in both the longitudinal and transverse directions.

[0063] Although not bound by theory, by providing a first belt pattern FBP having a longitudinal orientation, the inelastic region (221) appears to harmonize with the upper gathered region (220), improving the directionality of the continuous gathers in the longitudinal direction of the upper gathered region (220).

[0064] The crotch area (30) as described herein is provided with a first crotch pattern FCP. The first crotch pattern FCP may be an aesthetic pattern or a geometric pattern. The first crotch pattern FCP may have a longitudinal orientation according to the measurement methods described herein. Similar to the first belt pattern FBP, the longitudinal orientation of the first crotch pattern FCP can be determined by observation, measurement and / or image analysis. What is described by the longitudinal orientation according to the measurement methods described herein is the impression of being oriented longitudinally as perceived by the naked eye when observing a repeating visual presentation of the pattern, similar to what has been discussed for the first belt pattern FBP. Referring to Figure 6A, the crotch area (30) is visible from the side facing the garment and is provided with holes in the first crotch pattern FCP similar to those of the first belt pattern FBP. The first crotch pattern FCP also has a longitudinal orientation. Referring to Figures 6B, 11D, and the measurement method described below, the crotch region (30) in Figure 6B is provided with holes in the first crotch pattern FCP that are not the same as those in the first belt pattern FBP. Furthermore, the holes in the first crotch pattern FCP have a longitudinal orientation and therefore appear to be aligned with the first belt pattern FBP.

[0065] By providing both the first belt pattern FBP and the first crotch pattern FCP with longitudinal orientation, the non-elastic region (221) appears to harmonize with the crotch region (30), improving the integrated, underwear-like appearance of the article. Such a combination of the first belt pattern FBP and the first crotch pattern FCP is particularly useful for belt-type pants in which the annular elastic belt (40) and central chassis (38) are provided as separate parts. By providing both the first belt pattern FBP and the first crotch pattern FCP with longitudinal orientation, the visibility of the boundary between the different parts can be reduced. Both the first belt pattern FBP and the first crotch pattern FCP may be geometric patterns.

[0066] The first belt pattern FBP and the first crotch pattern FCP may have common elements. Having common elements means that, according to the measurement methods specified herein, the basic units of the first belt pattern FBP and the first crotch pattern FCP are the same or similarly provided. For example, the first belt pattern FBP and the first crotch pattern FCP in Figure 6A have common elements, which are holes arranged linearly in the longitudinal direction.

[0067] Common elements may be represented in different sizes, while their basic units are geometrically similar. Common elements may be arranged in similar orientations, colors, and densities. For example, referring to Figure 7, the cloud-like patterns of the second belt pattern SBP and the second crotch pattern SCP are made up of similar but further different sized clouds. Cloud-like patterns can function as common elements.

[0068] Common elements may be provided in different ways. For example, certain elements provided as a geometric pattern in the first belt pattern FBP may be provided as a printed pattern in the first crotch pattern FCP. In another example, certain elements provided as an emboss in the first belt pattern FBP may be provided as holes in the first crotch pattern FCP.

[0069] Referring to Figure 6B, the crotch region (30) may be provided with holes in the first crotch pattern FCP that are different from those in the first belt pattern FBP. Furthermore, if both the holes in the first belt pattern FBP and the first crotch pattern FCP are longitudinally oriented, a unified appearance is provided. However, in such a situation, measures may be taken so that the front and rear elastic belts (84, 86) overlap with the central chassis (38) and the first crotch pattern FCP does not interfere with the appearance of the first belt pattern FBP.

[0070] To prevent the interference discussed above, the front or rear elastic belts (84, 86) may be provided to have an opacity of at least about 25% or at least about 45% according to the measurement method specified herein. By providing such opacity and providing the first belt pattern FBP to have a longitudinal orientation, it is difficult to see through the material constituting the belt material, and therefore difficult to identify the first crotch pattern FCP through the belt material.

[0071] Referring to Figure 2B, in order to prevent the interference discussed above, the configuration of the garment-facing surface of the central chassis (38) may be adjusted with respect to the front and rear elastic belts (84, 86). The outer cover layer (42) may be the garment-facing surface of the crotch area (30), and a first crotch pattern FCP may be provided. The outer cover layer (42) may extend only partially in the longitudinal direction of the front waist panel (52) and the rear waist panel (54), and the distal portions of the front waist panel (52) and the rear waist panel (54) may not include the outer cover layer (42). That is, the longitudinal length of the outer cover layer (42) may be longer than the longitudinal length of the crotch panel (56) and shorter than the longitudinal length of the backsheet (60). In such a configuration, the distal portions of the front waist panel (52) and the rear waist panel (54) do not have the outer cover layer (42). Therefore, looking at the layer of elements between the garment-facing surface of the central chassis (38) and the back sheet (60) in Figure 2B, there is only a very small overlapping area (34) located on the waist panel (52) where the outer cover layer (42) is present. The longitudinal length of the overlapping area (34) between the front elastic belt (84) and the rear elastic belt (86) can be made as short as possible, for example, less than about 20 mm, less than about 15 mm, or less than about 10 mm, respectively.

[0072] The inelastic region (221) may further include a second belt pattern SBP. The second belt pattern SBP is a pattern different from the first belt pattern FBP, either a visual presentation or a similar pattern provided in a different manner, as discussed above. A similar pattern provided in a different manner means, for example, the first belt pattern FBP provided by embossing, and the second belt pattern SBP provided in color corresponding to the embossing. The second belt pattern SBP may be an aesthetic pattern or a geometric pattern. The second belt pattern SBP may have common elements with the first belt pattern FBP or the first crotch pattern FCP. The crotch region (30) may further include a second crotch pattern SCP. The second crotch pattern SCP is a pattern different from the first crotch pattern FCP, either a visual presentation or a similar pattern provided in a different manner, as discussed above. The second crotch pattern SCP may be an aesthetic pattern or a geometric pattern. The second crotch pattern SCP may have common elements with the first belt pattern FBP or the first crotch pattern FCP. The second belt pattern SBP and the second crotch pattern SCP may have common elements. Referring to Figure 7, the first belt pattern FBP and the first crotch pattern FCP are holes with longitudinal orientation having common elements, and the second belt pattern SBP and the second crotch pattern SCP are arrangements of holes representing clouds, where clouds do not necessarily have longitudinal orientation. Referring to Figure 8, the first belt pattern FBP and the first crotch pattern FCP are holes with longitudinal orientation having common elements, and the second belt pattern SBP and the second crotch pattern SCP are also embossed with longitudinal orientation having common elements.

[0073] The first belt pattern FBP, the first crotch pattern FCP, the second belt pattern SBP, and the second crotch pattern SCP may each have a pattern density according to the measurement method of this specification. To provide a specific aesthetic effect, the pattern density of a specific pattern can be selected. For example, the pattern densities of the first belt pattern FBP and the first crotch pattern FCP can be made to have a difference of less than about 10 points so that the inelastic region (221) appears to harmonize with the crotch region (30) and improves the appearance of the article as an integral undergarment. In belted pants, the visibility of the boundary between different parts can be alleviated. In another example, the pattern density may be provided with a gradient that gradually decreases from the distal edge (88) towards the proximal edge (90) and further into the crotch region (30).

[0074] Referring to FIG. 6A, when the first belt pattern FBP and the first crotch pattern FCP have common elements, are the same or very similar to each other, and further have a difference in pattern density of less than about 10 points, a highly harmonious appearance can be provided. Such a highly harmonious appearance can be accompanied by a well-finished product and also with a low intention from the pattern. Referring to FIG. 7, providing the second belt pattern FBP and the second crotch pattern SCP to the harmony of the pattern of FIG. 6A can help provide an accent and / or intention to the highly harmonious appearance of FIG. 6A.

[0075] The first belt pattern FBP and the first crotch pattern FCP are about 16 mm 2 ~ about 200 mm 2A higher-order pattern HOP can be formed with area dimensions such that the first belt pattern FBP and the first crotch pattern FCP are geometric patterns having common elements, and both the first belt pattern FBP and the first crotch pattern FCP have a non-directional orientation according to the measurement method herein. Non-directional orientation means that the pattern is not oriented in either the longitudinal or transverse direction. The directional orientation of the higher-order pattern HOP is determined by image analysis according to the measurement method herein. Specifically, the non-directional orientation has less than 35% longitudinal dispersion (dispersion %) at 90 degrees and less than 35% transverse dispersion (dispersion %) at 0 degrees. Specifically, the non-directional orientation may have less than 15% longitudinal dispersion and less than 15% transverse dispersion. What is meant by the higher-order pattern HOP is a pattern that has inconsistent intervals between the deformed parts, unlike the random repeating units described above. The inconsistent intervals may be alternating or variable. Due to inconsistent spacing, the pattern can provide a presentation of a shape larger in dimension than the dimensions of the individual deformations. Referring to Figure 9A, the first belt pattern FBP and the first crotch pattern FCP have seven deformations arranged in a circular pattern. The deformations may be holes. Referring to Figure 9B, the first belt pattern FBP and the first crotch pattern FCP have twelve deformations arranged in a diamond shape with an opening in the center. The deformations may be holes. Referring to Figure 9C, the first belt pattern FBP and the first crotch pattern FCP have twenty-six deformations arranged so that two leaves have a stem connecting them. The deformations may be holes. Referring to Figure 9D, the first belt pattern FBP and the first crotch pattern FCP have 80 deformable parts arranged in a chain-like shape, while the second belt pattern SBP and the second crotch pattern SCP each have 16 deformable parts arranged in a heart-like shape surrounded by chains similar to those of the first belt pattern FBP and the first crotch pattern FCP. All such deformable parts may be holes.Alternatively, a second belt pattern SBP or a second crotch pattern SCP, which may be heart-shaped, may be provided by embossing or printing.

[0076] The area dimensions of a higher-order pattern HOP are obtained as follows: First, the basic pattern of the higher-order pattern HOP is identified. The basic pattern represents, for example, the circular shape in Figure 9A, the diamond shape in Figure 9B, the two-leaf and stem shape in Figure 9C, the heart shape in Figure 9D, or the chain shape in Figure 9D. Such basic patterns may or may not share elements with neighboring patterns. The center point of one basic pattern is identified as C. Due to the non-directional orientation of the higher-order pattern HOP, four center points of four different higher-order pattern HOPs that are closest to each other can be extracted. The pattern closest to the basic pattern and / or the pattern that shares elements with the basic pattern is identified. The imaginary lines connecting the four center points represent a quadrilateral, typically a parallelogram, rhombus, or square, defining the HOP unit. If it is possible to draw two or more types of quadrilaterals using the four center points, the quadrilateral with the smallest area is identified and defined as the HOP unit. The HOP unit of this invention is approximately 16 mm². 2 ~about 200mm 2 It has an area of ​​.

[0077] Referring to Figure 9B, the center point of the higher-order pattern HOP is the central opening, which can be identified as C. Identify the pattern that is closest to the basic pattern. The imaginary lines connecting the four center points represent a square, defining the HOP unit of the pattern in Figure 9B. Referring to Figure 9C, the center point of the higher-order pattern HOP is the connection point of two opposing, leaf-like shapes, which can be identified as C. Identify the pattern that is closest to the basic pattern. The imaginary lines connecting the four center points represent a square, defining the HOP unit of the pattern in Figure 9C. Referring to Figure 9D, the center point of the higher-order pattern HOP is the center of a chain-like shape, which can be identified as C. Identify the pattern that is closest to the basic pattern. The imaginary lines connecting the four center points represent a diamond shape, defining the HOP unit of the pattern in Figure 9D. In Figures 9B, 9C, and 9D, the HOP unit area is indicated with a border. Each of the deformed parts in Figures 9A to 9D may have a diameter of approximately 0.4 mm to approximately 1.5 mm, and approximately 16 mm 2 ~about 200mm 2 It may have an area of ​​such size. By providing HOP units in such area dimensions, the pattern is easily identifiable to the naked eye, the repetition of the pattern is easily recognized, and it provides a high-quality aesthetic appearance.

[0078] By providing both the first belt pattern FBP and the first crotch pattern FCP with non-directional orientation, and further incorporating common elements of the higher-order pattern HOP, the inelastic region (221) appears in harmony with the crotch region (30), improving the overall appearance of the garment as if it were a single piece of underwear. In belt-type pants, the visibility of boundaries between different parts can be reduced.

[0079] 1. Whole article strength measurement method Forces are measured using an electric tensile testing machine equipped with a computer interface, such as MTS Criterion C42 running TestWorks 4 Software (available from MTS SYSTEMS (China) CO., LTD) or equivalent equipment. The load cell is selected so that the force result on the specimen under test is 10% to 90% of the load cell's capacity. The equipment is calibrated according to the manufacturer's instructions. All tests are conducted in a room maintained at 23±2°C and 50±5% relative humidity.

[0080] A hanger-type specimen holder (300), as shown in Figure 10, is attached to the tensile testing machine. Each holder is equipped with a rigid, linear, rubber-coated horizontal bar section (302) to prevent the specimen from slipping during testing. The outer diameter of the horizontal bar section (including the rubber coating) is 10.0 mm. The central axis of the horizontal bar section (302) is configured to remain parallel and within the same vertical plane throughout the entire testing process. The gauge length is determined by the following formula. Reference perimeter = 2 × (H + D + πD / 2) In the formula, H is the vertical gap between the horizontal bar sections (302), and D is the outer diameter of the bar.

[0081] The equipment is configured to perform the following steps:

[0082] [Table 1]

[0083] Insert the sample of article (20) onto the upper horizontal bar section (302) so that the bar passes through the waist opening and one leg opening of the article. Raise the crosshead until the specimen hangs above the lower bar and no longer touches the lower bar (302). Lower the crosshead so that the tare weight of the load cell is subtracted and the article can be inserted through the waist opening and the other leg opening without stretching the article. Adjust the article so that its longitudinal centerline LX is in the horizontal plane midway between the upper bar and the lower bar (302). Ensure that the center of the side portion in contact with the bar (302) is on the same vertical axis as the load cell of the instrument. While holding the article in place by hand as needed, slowly raise the crosshead until the force is 0.05 to 0.1 N, taking care not to apply unnecessary force. The gauge circumference at this point is the initial gauge circumference. The test is initiated by moving the crosshead upward at 254 mm / min until a force of 19.6 N is obtained, and then immediately returning the crosshead to its initial gauge circumference at the same speed. The force at the maximum circumference at 19.6 N and at 70% of the maximum circumference while the test segment is loaded and unloaded is recorded.

[0084] The maximum circumference (mm) at 19.6N is defined as the fully stretched circumference W1. The circumference at 70% stretch is defined as the fully stretched circumference (mm) × 0.7. The force (N) in the loaded segment of the test at 70% stretch is defined as the stretched circumference force. The force (N) in the unloaded segment of the test at 70% stretch is defined as the fitted circumference force. Five samples are analyzed, their average is calculated, and each is reported in units of 1 mm or 0.01 N.

[0085] 2. Opacity The opacity of a material or combination of materials is the degree to which light is blocked by that material. A higher opacity value indicates that the material blocks light more effectively. Opacity can be measured using a spectrophotometer with a computer interface, such as 0° illumination / 45° detection, ambient optical shape, or HunterLab LabScan XE running Universal Software (available from Hunter Associates Laboratory Inc. in Reston, Virginia). Instrument calibration and measurements are performed using standard black and white calibration plates provided by the supplier. All tests are performed in a room maintained at approximately 23±2°C and 50±5% relative humidity.

[0086] The spectrophotometer is configured for an XYZ color scale, D65 light source, and 10° standard observer, along with a nominally set UV filter. The instrument is standardized using a 44.45 mm (1.750 inch) field of view according to the supplier's procedure. After calibration, the software is set to the Y opacity procedure, which instructs the operator to cover the sample with either a white or black calibration tile during measurement.

[0087] To obtain the sample, apply a cold spray such as La Pointique Int'l Ltd.'s Cold spray 829, then remove the front or rear elastic belt from the rest of the article by manually removing the central chassis, and bond the belt to the central chassis. Open the side seam of the belt, thus removed from the central chassis, with scissors. For analysis, cut the inelastic region of the belt into 101.6 mm × 101.6 mm sections using scissors. Before testing, pre-condition the sample at 23°C ± 2°C and 50% ± 5% relative humidity for 2 hours.

[0088] Place the sample on the measurement port. The sample must completely cover the port with the side of the item facing the port that corresponds to the side of the item facing the port. Cover the test specimen with a white standard plate. After taking the reading, remove the white tile without moving the test specimen and replace it with a black standard tile. Take a second reading and calculate the opacity as follows. Opacity = (Y value) (黒色裏材) / Y value (白色裏材) ) × 100

[0089] Analyze similar areas in a total of three belts and record their opacity results. Calculate the average opacity and report it in units of 0.1%.

[0090] 3. Longitudinal orientation by observation This measurement method provides a visible random repeating pattern, defined as a pattern that is visually recognizable to the naked eye when observed from a distance of 10 cm. Referring to Figures 11A to 11D, identify the basic unit, which is the smallest complete unit of the pattern repeated to create the pattern and capable of enclosing a specific area. Within the basic unit, identify the nearest adjacent deformation or print in the longitudinal and transverse directions. Measure the distance between the nearest adjacent deformation / print in the longitudinal direction (Y) and the nearest adjacent deformation / print in the transverse direction (X) using a scale (unit: 0.1 mm). The Y and / or X intervals may be negative, as in the case of the Y interval in Figure 11C.

[0091] Patterns with an X-spacing that is at least 10% greater than the Y-spacing are considered to have longitudinal orientation. Analyze five parts of the same pattern, calculate their average, and report it in percentages.

[0092] 4. HOP unit area This measurement method is provided for higher-order patterns called HOPs. A HOP is a geometric pattern that is visually recognizable to the naked eye when observed from a distance of 10 cm and has inconsistent spacing between deformations. The inconsistent spacing may be alternating or variable. Repeats of HOPs made up of numerous deformations are identified by observation. Referring to Figures 9A-9D, the HOP in Figure 9A is circular, in Figure 9B it is square, in Figure 9C it is a leaf and stem, and in Figure 9D it is a heart surrounded by a chain. Identify the center of one HOP as C. Such a HOP is the basic pattern. Identify and extract other HOPs that are closest to the basic pattern or that share elements with the basic pattern. From these neighboring HOPs, identify the four closest center points. The imaginary lines connecting the four center points represent a quadrilateral. If it is possible to draw two or more types of quadrilaterals using the four center points, identify the quadrilateral with the smallest area and define it as the HOP unit. Measure the sides and / or diagonals of the quadrilateral using a JIS-certified metal scale or equivalent, and calculate the area of ​​the quadrilateral.

[0093] Analyzing five HOP units with the same pattern, 1 mm 2 Report in units.

[0094] 5. Image Analysis 5-1. Sample Preparation The article (20) sample is mounted on a rigid plastic plate of an appropriate size that allows the elastic belt (40) of the sample to be attached when it is stretched to 65% to 90% of its fully stretched circumference W1. For the measurement of the article samples in Examples 1 and 2, a rigid plastic plate with dimensions of 250 mm in the transverse direction and a thickness of 4 mm was used. Furthermore, a stretch block is inserted between the front side and the plastic plate of the sample. Regardless of the size of the sample, the stretch block has dimensions of 110 mm in the transverse direction, 170 mm in the longitudinal direction, and a thickness of 25 mm. The stretch block is inserted into the center of the article so that any elastic body of the central chassis (38) is substantially stretched.

[0095] 5-2. Image Acquisition Place the sample prepared above horizontally on a non-reflective black background plate with the front side facing upwards. Place a Canon camera (Canon E2 6D Mark II) or equivalent with a lens (EF24~105mm f / 4L IS2 USM) directly above the sample, 1050mm in length. Place two bar lights (Smart Vision Lights LHF 300 or equivalent) 650mm transversely and 300mm vertically from the sample, with the light surfaces facing at an angle of 45±6 degrees from the horizontal, and the longer dimension of the bar lights parallel to the longitudinal axis of the sample. Set the camera's focal length to 64mm. The image acquisition settings are ISO:400, F:5.0, exposure time:1 / 160 sec.

[0096] 5-3. Image Analysis of Pattern Density a) Import the image acquired above into ImageJ software (version 1.52h, National Institute of Health, USA) or equivalent and convert it to 8-bit. b) Set the scale in relation to the rigid plastic plate. c) The analysis areas of the First Belt Pattern (FBP) and the First Crotch Pattern (FCP) are simultaneously cut out as 50mm x 50mm squares from approximately the center of the transverse direction of the article, while avoiding areas with wrinkles, shadows, or high reflectivity, and then arranged. The images obtained by this process were similar to Figure 12A of the FBP of Example 1, Figure 13A of the FCP of Example 1, Figure 14A of the FBP of Example 2, and Figure 15A of the FCP of Example 2. This order of the figures for each pattern (12, 13, 14, 15) is the same as the remaining images described below. d) The cropped image is filtered using the ImageJ "FFT bandpass filter" with the "function of autoscale after filtering" and "surtulation when autoscaling" marks selected. Large structures up to 10 pixels are filtered, and small structures up to 3 pixels are filtered. e) Convert the filtered image obtained in step d) to black and white using a threshold of 70 gray. f) Use the ImageJ built-in plugin called "particle analysis" to measure 0.2mm 2 To filter out particles smaller than a certain size, apply the threshold image obtained in step e), set the "Show" pull-down menu to "Masks", create a sharp pattern image, and select the marks in the summary table. The sharp pattern images obtained by this step in Examples 1 and 2 are shown in Figures 12B-15B. Pattern density is defined as the area % from the summary table. Analyze five samples, calculate their average, and report in units of 0.1 points.

[0097] 5-4. Image analysis of longitudinal / transverse dispersion g) The sharp pattern image obtained in step f) is subjected to a T-filter using the "Gaussian Blur" filter in ImageJ with a sigma (radius) of 1 mm. The images obtained by this step in Examples 1 and 2 are shown in Figures 12C to 15C. h) To calculate orientation variance, apply the ImageJ built-in plugin called "Orientation" to the blurred image obtained in step g) and calculate the orientation variance. Select the following analysis parameters from the display table marks: Method: Fourier component, Nbins: 5, Histogram start: -45, Histogram end: 135. i) Obtain directional variance from the output table. The output table contains variance for each angle: -45°, 0°, 45°, 90°, and 135°. Transverse variance is defined as the variance % at 0°. Longitudinal variance is defined as the variance % at 90°. Analyze five samples, calculate their mean, and report to the nearest 0.01 point. [Examples]

[0098] Examples 1 and 2 were fabricated using the belt configuration shown in Figure 2A, the first belt pattern FBP and the first crotch pattern FCP as shown in Figures 6A and 6B, and the elastic / bonding profile plans shown in Table 1. Actual photographic images of the FBP of Example 1, the FCP of Example 1, the FBP of Example 2, and the FCP of Example 2 are provided as Figures 12A, 13A, 14A, and 15A, respectively. The longitudinal / transverse dispersion and pattern density of Examples 1 and 2 were obtained as shown in Table 2.

[0099] [Table 2] ( * 1) In Table 1, "abdominal cut" refers to the removal of elasticity in the transverse central region of the elastic strand, resulting in an effective elastic length of 68%.

[0100] [Table 3]

[0101] The articles of Examples 1 and 2 provide an aesthetically pleasing, integrated appearance. The articles of Examples 1 and 2 also have improved stretchability for easier application, improved fit to prevent sagging, improved comfort and softness, and improved breathability for skin health.

[0102] Display test based on synthesized vision Examples A to H were created as composite photographs of pant-type articles, showing their appearance from the front, as shown in Figures 16A to 16H. All deformed parts are holes with an aspect ratio of 2 or less and a nearly circular shape. The composite photographs were created to show how the article would look when worn and to have the following characteristics. Examples C and D are 79 mm each. 2 and 20mm 2 It has a pattern that is a higher-order pattern with a HOP unit area.

[0103] [Table 4]

[0104] We recruited 20 panelists who are generally caregivers of infants using size 4 or 5 (L or XL) pull-up diapers and have experience using a mix of major brands. The panelists were shown all appearances of Examples A-H and asked to rate them using five evaluation scales: "Poor" = 0, "Good" = 25, "Good" = 50, "Very Good" = 75, and "Excellent" = 100. These values ​​are shown in Table 4 below. The scores were then averaged.

[0105] [Table 5] ( * 1) The marking of the example number after the score indicates that it is "statistically significantly better" than the example marked at a 90% confidence level. For example, the "overall" evaluation of Example B was statistically significantly better than that of Examples G and H.

[0106] According to the above tests, Examples B, C, and D, which satisfy the requirements of the present invention, have a statistically significant overall preference over at least some of Examples E to H, which do not satisfy the requirements of the present invention.
