摘要:
A disposable wearable absorbent article having a hook and loop fastening system that comprises a nonwoven female fastening material and a male fastening material with a plurality of bidirectional micro-sized hooks, each having a cap and at least one arm. The height of each hook and cap may be defined relative to the overall thickness of the female fastening material. Caps may have a vertical engagement effective area that has: (a) at least two sides that are substantially parallel; (b) a width-to-thickness aspect ratio from 1 to 2; and (c) an area from 40,000 to 120,000 μ2. Caps may have an overall recessed width and a deepest recessed depth that is defined relative to the overall fiber cross-sectional dimension.

The present invention relates to a disposable absorbent article comprising a chassis defining a front waist region, a back waist region, and a crotch region disposed between the front waist region and back waist region. The article includes a fastening system that includes one or more fastening devices, each having at least one tab member configured to releasably connect to a slot member when, for instance, fastening the article to the body of the wearer. A variable stiffness member is associated with at least a portion of the fastening device that, in response to a predetermined external stimulus, reduces its stiffness to correspondingly reduce the stiffness of the fastening device.

A method for producing a multilayer nonwoven web including a monocomponent fiber layer and a multicomponent fiber layer is disclosed. The method may include the steps of spinning a plurality of monocomponent fibers at a beam of monocomponent fiber spinnerets and directing them toward a belt to form a monocomponent batt layer; spinning a plurality of multicomponent fibers at a beam of multicomponent fiber spinnerets and directing them toward the belt to form a multicomponent batt layer, wherein the layers are laid on the belt one superadjacent the other to form a batt; and bonding the batt in a pattern of thermal bonds to form a multilayer nonwoven web.

A fastening system includes an engaging component and a receiving component. The engaging component has a plurality of engaging elements capable of engaging the receiving component. The receiving component includes a nonwoven fabric having composite fibers, an embossed section, and a non-embossed section. The composite fibers are bonded together in the embossed sections. The composite fibers include a first propylene polymer and a second propylene polymer, wherein the first and second propylene polymers extend continually in a longitudinal direction and are arranged such that the second propylene polymer is associated with the first propylene polymer such that the composite fiber forms a crimp therein. The embossed sections have a plurality of zigzag unit patterns arranged in a machine direction which have a ratio of W1/W2 in the range of about 0.5 to about 2.0.

A nonwoven web is provided. The nonwoven web contains a side-by-side composite fiber having crimps. The composite fiber contains first and second propylene polymers. The nonwoven web contains a bonded portion that contains a bonding pattern containing zigzag unit patterns. The zigzag unit patterns are continuous and substantially parallel with a first direction and are disposed in a second direction at predetermined intervals. A triangle formed by adjacent three contact points of a first diagonal line and a second diagonal line of the unit pattern contains a part of the unit pattern that is adjacent to the triangle in the second direction.
摘要:
A mechanical fastening system having an engaging component and a receiving component. The receiving component has a first bond line, a second bond line, a bond zone, and a plurality of consecutive sweep regions. The second bond line is disposed adjacent to the first bond line such that a portion of the second bond line overlaps a portion of the first bond line. The bond zone circumscribes the first bond line and the second bond line. The plurality of consecutive sweep regions are disposed within the bond zone. At least one sweep region includes a portion of both the first bond line and the second bond line, and the remaining sweep regions include at least a portion of the first or the second bond lines. The receiving component has a bond ratio greater than or equal to about 1 and less than or equal to about 20.
