Abstract: The present invention relates to covers and in particular covers for beds which are characterized by the presence of two or more groups of strips, wherein each group comprises two or more strips. These strip groups are arranged relative to one another in different directions and in particular woven together. The present invention also relates to further applications of this construction principle, for example in cushions.

Abstract: A method of producing a laminate material includes the steps of providing a first flexible sheet material; providing a second flexible sheet material having a first surface and a second surface, and also having a first width of 1×; stretching the second flexible sheet material in a cross-machine direction to a second width of between about 1.2× and 3× when in a flattened state; necking the second flexible sheet material to produce an accordion shape, thereby reducing the second width of the sheet material to a third width, less than the width of the first width, such that the third width is between 0.65× to 0.975× when in an accordion shape; applying adhesive to the first surface of the second flexible sheet material with a slot coat adhesive process; and joining the first flexible sheet material to the first surface of the second flexible sheet material.

Abstract: A nonwoven composite that exhibits latent elastic properties is provided. More specifically, latent elasticity may be imparted by blending a thermoplastic elastomer with a polyolefin that is capable of forming semi-crystalline domains among the amorphous elastomeric chains, and then forming a film from the blend. The film is then stretched in one or more directions to orient the amorphous elastomer chains. Without intending to be limited by theory, the present inventors believe that the oriented state of the amorphous chains may be held in place by the relatively stiff semi-crystalline olefin domains. Subsequently, the stretched film may be activated (e.g., heated) to shrink the film and provide it with “latent” stretchability. For instance, the stretched film may be heated at or above the softening temperature of the polyolefin to soften the crystalline domains and allow the amorphous chains to return to their unoriented state.

Abstract: In some embodiments, a nonwoven fabric includes a first web that is at least partially formed of extruded strands which include an auto-adhesive material. The nonwoven fabric is adapted to be bonded to another item that includes a similar auto-adhesive material. In other embodiments, a method of forming a nonwoven fabric includes extruding a plurality of strands that are formed of an auto-adhesive material. The method further includes routing the plurality of strands toward a moving support, depositing the plurality of strands onto the moving support, and then stabilizing the plurality of strands to form a web. In other embodiments, a fastening system includes a nonwoven fabric that has a web which is formed of a plurality of extruded strands that include an auto-adhesive material. The fastening system further includes a foam layer that has a surface with a plurality of free-standing struts that include a similar auto-adhesive material.

Abstract: A breathable multilayered thermoplastic film that is a liquid barrier and has a WVTR of at least about 300 g/m2/24 hours and includes exterior layers that include from about 0.005 to about 0.2 weight percent of a polyorganosiloxane or a mixture of polyorganosiloxanes is provided.

Abstract: Fibers that exhibit good elasticity or extensibility and tenacity, and low modulus are prepared from propylene-based copolymers. The propylene-based copolymers comprise at least about 50 weight percent (wt %) of units derived from propylene and at least about 8 wt % of units derived from one or more comonomers other than propylene, e.g., ethylene. Particularly preferred propylene copolymers are characterized as having 13C NMR peaks corresponding to a regio-error at about 14.6 and about 15.7 ppm, the peaks of about equal intensity. In one aspect of the invention, fibers are subjected to stress-induced crystallization by subjecting the fiber to tensile elongation during draw.

Abstract: Extensible bicomponent fibers and webs particularly adapted for disposable personal care product component applications. Sheath/core configurations providing desirable feel properties for elastic embodiments when compared with conventional elastic fibers and webs are obtained with specific olefin polymer combinations and sheath configurations.
