Aspects herein are directed to a composite nonwoven textile suitable for use in apparel and other articles that are resistant to pilling. The composite nonwoven textile may be finished by one or more of applying a chemical binder to a first face of the composite nonwoven textile and forming thermal bonding sites. The chemical binder and the thermal bonding sites help to secure fiber terminal ends and minimize the formation of pills.

A non-fibrous film has a non-weakened portion and a weakened portion having at least one mechanical property having a value that is lower than the value of the mechanical property of the non-weakened portion. The film has an optical characteristic including a clarity of at least 75 percent.

A composite textile fabric that includes a first (face) fabric layer, and a second (back) fabric layer that is formed concurrently with the first fabric layer in a plaited construction. The second fabric includes a plurality of anchored regions at which the second fabric layer is anchored to, and in intimate contact with, the first fabric layer. The second fabric layer also includes a plurality of floating regions, overlying and unattached to the first fabric layer, interspersed between the anchored regions.

Described herein is a method for producing a biofabricated material from collagen or collagen-like proteins. The collagen or collagen-like proteins are isolated from animal sources or produced by recombinant DNA techniques or by chemical synthesis. The collagen or collagen-like proteins are fibrillated, crosslinked, dehydrated and lubricated thus forming the biofabricated material having a substantially uniform network of collagen fibrils.

A process for producing a nonwoven fabric comprising forming a polymer composition comprising a primary polypropylene and at least one secondary polyolefin; in a spunbond process, forming fibers then fabric from the polymer composition; and exposing the fabric to an heating environment within a range from 50° C. to 250° C.

A multi-layered web is disclosed that is resilient and/or elastic in the Z-direction. Thus, when the web is compressed, the web assumes a compacted state and then expands to an expanded state when the compressive forces are removed. In one embodiment, the multi-layered web includes a middle layer made from a resilient blend of fibers positioned inbetween two outer layers. The middle layer, for instance, can contain elastomeric fibers, three-dimensional fibers, and/or debonded fibers.

An article of apparel includes a composite material. The composite material includes a pliable first layer and a resilient second layer, where the first and second layers are secured to each other via a patterned strand network. In forming the composite material, the second layer is stretched and maintained under tension while the first layer is secured to the second layer via the patterned strand network. The tension on the second layer is then released, resulting in contraction of the second layer in relation to the first layer and an outward buckling or protrusion of the first layer in relation to the second layer to form protruding cells along the composite material that are bounded by portions of the patterned strand network. The patterned strand network can be formed using embroidery with one or more auxetic patterns in the stitching.

A composite comprising a non-fibrous organic polymer aerogel layer having a first surface and an opposing second surface and a support layer having a first surface and an opposing second surface is disclosed. An interface can be formed between a portion of the first surface of the aerogel layer and a portion of the second surface of the support layer such that the aerogel and support layers are attached to one another. A majority of the volume of the aerogel layer does not have to include the support layer. The composite can have a thickness of 3 mils to 16 mils.

The methods herein relate to assembling an elastic laminate with a first elastic material and a second elastic material bonded between first and second substrates. During assembly, an elastic laminate may be formed by positioning the first and second substrates in contact with stretched central regions of the first and second elastic materials. The elastic laminates may include two or more bonding regions that may be defined by the various layers or components of the elastic laminate that are laminated or stacked relative to each other. In some configurations, a first plurality of ultrasonic bonds are applied to the elastic laminate to define a first bond density in the first bonding region, and a second plurality of ultrasonic bonds are applied to the elastic laminate to define a second bond density in the second bonding region, wherein the second bond density is not equal to the first bond density.

The present disclosure provides a polymeric membrane. The polymeric membrane includes a first thermoplastic elastomer layer that comprises a styrenic thermoplastic. The thermoplastic elastomer layer has a foam structure. The polymeric membrane can further include an optional second thermoplastic elastomer layer in contact with the first polyolefin layer.
