Description

Technical Field

[0001] (Related Application) This application claims the benefit of co-pending U.S. Provisional Patent Application No. 63 / 160,079, filed on March 12, 2021, which is incorporated herein by reference.

[0002] The present invention relates to a stretch laminate that can be used as a component of an absorbent article device (e.g., diapers, pants, incontinence devices).

Background Art

[0003] Side panels or handles of absorbent article devices (e.g., diapers, pants, incontinence devices) are usually made of a stretch laminate (or elastic composite) fabric because they can stretch, conform, and allow for freer movement of the body. Stretch laminates (or composites) utilizing one or two nonwoven web layers adhered to an elastic film are known.

[0004] In open diapers, manufacturers typically purchase stretch laminates, hook tapes, and adhesives separately and assemble them mechanically to form handles. In pant diapers, some include surface fasteners (mechanical fasteners) on the side panels to facilitate checking and removing the pants. Pant diaper manufacturers also usually purchase stretch laminates, hook tapes, and adhesives separately and assemble them mechanically to form the pants. Separately purchasing stretch materials, hooks, and adhesives requires multiple processing stations on the diaper manufacturing machine, including unwinding, cutting, adhesive application, and bonding. These processing steps each require machinery, operators, and maintenance, and are associated with the raw materials required for assembly, including scraps of each material.

[0005] The manufacturers' interest lies in a new stretchable laminate featuring integrated fixing hooks (i.e., hooks already bonded to the laminate and ready for processing on the diaper manufacturing machine) that reduce the number of processing steps. This reduces the number of incoming raw materials, thereby reducing the scrap generated by joining incoming raw materials. [Overview of the Initiative] [Problems that the invention aims to solve]

[0006] Manufacturing these new stretchable laminates in the roll shapes required by their manufacturers presents several challenges, including sufficient adhesive strength between the hook and the laminate, abrasion resistance of the hook ends, uniform roll formation, and cost-effectiveness. There is a risk that the adhesive layer between the nonwoven fabric and the stretchable film may fail when the hook is subjected to a strong peeling or shearing force that could detach it from the laminate. Furthermore, laminating the hook into the stretchable laminate can result in a thicker web in the area where the hook is laminated, creating challenges in winding rolls with uneven thickness. There are also challenges in unwinding during the customer's process and increased effort required to unwind the roll if the hook engages with an opposing layer.

[0007] Therefore, there is a need for these new stretchable laminates (i.e., stretchable laminates with integrated hooks) to address and overcome the limitations of currently available materials. [Means for solving the problem]

[0008] The components for the incontinence device include an expandable laminate comprising a stretch zone having an elongation with a strain (set) of less than approximately 20% under a tensile load of 10 N / inch, a dead zone having an elongation at least approximately 20% lower than the elongation of the stretch zone, and a hook layer installed within the dead zone of the expandable laminate, wherein the hook layer has a height H1, the stretch zone has a height H2, and the dead zone in which the hook layer is installed has a height H3, and H1 + H2 ≥ H3.

[0009] For the purpose of illustrating the present invention, a currently preferred embodiment is shown in the drawings, but it will be understood that the present invention is not limited to the exact arrangement and means shown. [Brief explanation of the drawing]

[0011] Some non-limiting embodiments of the present invention are shown in Figures 1-9, where similar parts have similar identifiers.

[0012] Generally, the present invention relates to a component of an absorbent article 100 or an incontinence device 100, such as a handle or a side panel 200. The incontinence device may be for infants / toddlers / adults and may be used in an open-type incontinence device, for example, as shown in Figures 8-9. The component combines a stretchable laminate with an integrated hook layer. As described above, the component is designed to simplify the assembly (or manufacture) of the incontinence device by reducing the number of steps in the assembly process of the incontinence device.

[0013] Generally, part 10 includes a hook layer 20 attached to a stretchable laminate 30. The hook layer 20 and the stretchable laminate 30 have a coincidental (or parallel) mechanical direction (MD) and a width direction (TD). In the drawings (Figures 1-6), TD crosses the surface of the sheet, while MD (perpendicular to TD) passes through (or enters) the surface of the sheet. The stretchable laminate 30 has a stretch zone 32 extending in the MD and a dead zone 34 extending in the MD. In cross-section, the stretch zone 32 has (or may have) a first nonwoven fabric 40, a second nonwoven fabric 42, and an elastic film 44 laminated between the first nonwoven fabric 40 and the second nonwoven fabric 42. In cross-section, the dead zone 34 has (or may have) the first nonwoven fabric 40 bonded to the second nonwoven fabric. The hook layer 20 can be placed within the dead zone 34. In other embodiments, as shown in Figures 3E and 4A, the dead zone 34 has (or may have) in cross-section a first nonwoven fabric 40 bonded to a second nonwoven fabric and a portion of an elastic film between the nonwoven fabrics.

[0014] In the illustrated embodiment, the layers (40, 42, 44) are adhered to each other. Any conventional adhesive can be used. The adhesive can be sprayed or extruded in any conventional manner. For example, the adhesive can be distributed such that the ratio of the adhesive stripe width to the distance between adjacent adhesive stripes (described in U.S. Patent No. 8,716,547, which is incorporated herein by reference) is 0.33 to 1, or preferably less than 0.33, in order to reduce the amount of adhesive used. Adhesive stripes are shown in FIGS. 1B and 3C. The adhesive application pattern can be continuous over the entire surface, intermittent, linear, or punctate. Although adhesive 46 is shown, any conventional adhesion method can be used, including thermal adhesion, ultrasonic adhesion, two-component fibers used for thermally adhering non-woven fabrics, self-adhesion through the molten elastomer of an elastic film, and / or adhesion of encapsulated fiber non-woven fabrics, and combinations thereof.

[0015] The non-woven fabric can be any non-woven fabric. Such non-woven fabrics include carded thermal bond non-woven fabrics, spunlace non-woven fabrics, spunbond non-woven fabrics, meltblown non-woven fabrics, combinations of spunbond / meltblown non-woven fabrics, dry-laid non-woven fabrics, air-laid non-woven fabrics, wet-laid non-woven fabrics, hydroentangled non-woven fabrics, needle non-woven fabrics, or any combination thereof. They can use multi-component fibers or filaments, or mixtures of different fibers or filaments, or both. The first non-woven fabric in the stretch zone and the first non-woven fabric in the dead zone can be the same or formed from the same single or continuous material. The second non-woven fabric in the stretch zone and the second non-woven fabric in the dead zone can be the same or formed from the same single or continuous material. In one embodiment, the first non-woven fabric is a carded spunlace non-woven fabric. In another embodiment, the second non-woven fabric is a carded thermal bond non-woven fabric. As shown in FIGS. 3C and 3D, the first and second non-woven fabrics can have various heights or can include additional layers of non-woven fabric. Examples of non-woven fabrics that can be used in the stretchable laminate are shown in Table 1.

[0016] [Table 1]

[0017] Other combinations of non-woven fabrics may be used, and this specification is not limited to the non-woven fabrics cited in these examples.

[0018] The hook layer 20 can include hooks protruding from the substrate 25. As is well known, these types of strips are usually extruded. The hooks can extend across the substrate 25 from side edge to side edge of the strip, i.e., except for the selvage. These hooks are installed in the dead zone. "In register" means that the hooks are only in the dead zone and do not extend onto or overlap the stretch zone. In some embodiments, as shown in FIGS. 3E, 4A, and 7, the hook layer may have ears 22. In these embodiments, the hooks are installed in the dead zone. In other embodiments, the hook layer is installed in a dead zone that includes hooks of the hook layer that do not extend into the stretch zone. As long as the hook layer is installed in the dead zone, the hook layer may be offset from or spaced apart from the side edges of the stretch zone, such as in FIGS. 3B and 5B. The hook layer may include two or more strips, as shown in FIGS. 2-5. The hook layer may be as described in International Publication No. WO 2019 / 145647, and / or International Publication No. WO 2019 / 145646, and / or International Application No. PCT / FR2 / A52380, and / or International Application No. PCT / FR2020 / 052379, all of which are incorporated herein by reference.

[0019] The hook layer and the stretch laminate are adhered (or joined) to each other by one or more of adhesives, thermal adhesion, ultrasonic adhesion, fusion adhesion, mechanical adhesion by encapsulated fibers, and / or calendaring, and combinations thereof.

[0020] The stretch zone may be activated, and the height H2 of the stretch zone may be measured after activation. Activation may be performed by a ring roller. The height of the activated stretch zone may be higher than the height of the stretch zone before activation.

[0021] During use, the hook layer is used to removably attach the free end of a handle or side panel to the chassis of the incontinence device by engaging with loop material attached to the chassis of the incontinence device. Therefore, the apex of the hook on the hook layer should be at or near the height of the stretch zone material so that the stretch zone material does not hinder attachment (or create rolls of varying thicknesses). In some embodiments, this can be expressed as follows: the hook layer has a height H1, the stretch zone has a height H2, and the stretch laminate in the portion of the hook layer that is installed in the dead zone has a height H3, where H1 + H2 > H3, but the difference is less than 10%. In other embodiments, this can be expressed as follows: the hook layer has a height H1, the stretch zone has a height H2, and the stretch laminate in the portion of the hook layer that is installed in the dead zone has a height H3, where H2 ≥ H3.

[0022] In some cases, H2 is 0.3 mm to 2.0 mm, preferably 0.4 mm to 1.5 mm, and more preferably 0.5 mm to 1.0 mm.

[0023] In some cases, H1 is 0.20 mm to 0.5 mm, preferably 0.25 mm to 0.45 mm, and more preferably 0.30 mm to 0.45 mm.

[0024] In some cases, H3 is 0.25 mm to 2.5 mm, preferably 0.35 mm to 1.5 mm, and more preferably 0.45 mm to 1.0 mm.

[0025] Pressure 0.1 kPa and diameter 23 mm, i.e., approximately 415 mm 2By using a circular caliper and a "PRECISION THICKNESS TESTER" that references "D-2005-V", the values ​​of H1 and / or H2 and / or H3 can be measured.

[0026] If necessary, H2 can be measured using an optical measuring device, such as a Leica Z16APO type macroscope 0.57x-9.2x.

[0027] [Table 2]

[0028] The hook layer placed on the components of the absorbent material device has a mechanical direction (MD) length of less than 300 mm in one case, less than 250 mm in another, and less than 200 mm in yet another.

[0029] The hook layer includes hooks with a height of 0.12 to 0.33 mm, specifically hooks with a height of 0.18 to 0.32 mm.

[0030] In Figures 1A to 6, the hook layer is shown laminated directly onto the nonwoven fabric, i.e., without adhesive. In some other cases, the hook layer can be attached to the elastic laminate by other techniques such as ultrasonic bonding or thermal bonding.

[0031] In Figure 3D, area 36 represents the activated area 36, ​​and area 32 represents a stretch zone 32 that is different from the activated area 36. In another embodiment, the activated area or stretch zone may be the same or different.

[0032] The hook layer placed on the absorbent material device has a length in the machine direction that is greater than 30 mm, sometimes greater than 40 mm, sometimes greater than 50 mm, and sometimes greater than 60 mm.

[0033] In Figures 1B and 3C, the adhesive is applied linearly to the central part of the elastic film and to the entire area in contact with the edges of the elastic film. In the embodiments of Figures 1A, 2, 3A, 3B, 3D, 3E, 4A, 5A, 5B, and 6, the adhesive is applied to the entire surface, but it can also be done similarly to that shown in Figures 1B and 3C.

[0034] The stretch zone has elongation with strain of less than 20% (preferably 5% to 15%) under a tensile load of 10 N / inch. The test method used to measure such strain may be the same as that described.

[0035] The term “stretch zone with elongation with less than 20% strain” is used to mean a material that, when stretched under the effect of a lateral tensile force, is suitable to essentially return to its initial shape and dimensions after the aforementioned tensile force is released. As an example, a material may, at ambient temperature (23°C), be stretched to 100% of its initial dimensions and then retain a residual deformation or set (such residual deformation is also called “permanent set” or “set”) that is less than 20% of the initial dimensions (before stretching). The strain can be measured as described in European Patent Application Publication 1783257, specifically paragraphs

[0056] to

[0062] of European Patent Application Publication 1783257, which incorporates its contents by reference, and which describes a detailed example of strain measurement.

[0036] In some embodiments, the stretch zone has an elongation accompanied by a strain of 5% to 15%.

[0037] The term "at a tensile load of 10 N / inch" is similar to the strain test described above, where the initial elongation value at 10 N is recorded during the initial elongation of the test sample.

[0038] In some embodiments, the elongation of the dead zone at a tensile load of 10 N / inch is at least 20% lower than the elongation of the stretch zone at a tensile load of 10 N / inch. In some other embodiments, the elongation of the dead zone at a tensile load of 10 N / inch is at least 50% lower than the elongation of the stretch zone at a tensile load of 10 N / inch.

[0039] In some embodiments, to obtain a stretch zone, the elastic film and / or the first nonwoven fabric are laminated when the elastic film is under tension (or is stretched), as described in U.S. Patent No. 8,236,121, the contents of which are incorporated by reference. The hook layer is 15 gsm to 120 gsm, specifically 15 gsm to 70 gsm. The height of the substrate is 0.04 mm to 0.1 mm, specifically 0.2 to 0.8 mm.
