A knitted portion with a resiliently longitudinal stretchability from about 5 to about 200 linear percent over its quiescent longitudinal dimension is also useful.

A radially expandable stent-graft endoprosthesis is provided. The graft included in the stent-graft is a knitted tubular structure circumferentially disposed and securably attached to the stent. The knitted tubular structure has a warp knit pattern of interlacing yarns with at least a two-needle underlap to provide greater than 150 percent longitudinal stretchability while substantially inhabiting dilation. A knitted tubular graft and a knitted medical fabric with greater than 150 percent longitudinal stretchability are also provided.

An article of apparel is disclosed that includes zones with a textile having a structure that changes or is otherwise modified by a physical stimulus, such as the presence of water or a temperature change, to modify a property of the textile. The zones may be along a center back area and side areas of the apparel, and the textile may increase in air permeability when exposed to water. The zones may also be in an upper area of the torso and in a lower back area, and the textile may increase in texture when exposed to water. In some embodiments, slits are formed in the textile.

Surface films, paints, or primers can be used in preparing aircraft structural composites that may be exposed to lightning strikes. Methods for making and using these films, paints or primers are also disclosed. The surface film can include a thermoset resin or polymer, e.g., an epoxy resin and/or a thermoplastic polymer, which can be cured, bonded, or painted on the composite structure. Low-density electrically conductive materials are disclosed, such as carbon nanofiber, copper powder, metal coated microspheres, metal-coated carbon nanotubes, single wall carbon nanotubes, graphite nanoplatelets and the like, that can be uniformly dispersed throughout or on the film. Low density conductive materials can include metal screens, optionally in combination with carbon nanofibers.

Cushioning net structures comprise random loops, such as three-dimensional random loops, bonded with one another, wherein the loops are formed by allowing continuous fibers, made of ethylene/α-olefin interpolymers, to bend to come in contact with one another in a molten state and to be heat-bonded at most contact points. The structures provided herein have desirable heat resistance, durability and cushioning property. The cushioning structures are used in furniture, vehicle seats etc.

Unique blends of fibers that incorporate synthetic cellulosic fibers to render fabrics made with such blends more durable than fabrics made with natural cellulosic fibers such as cotton. While more durable than cotton, the synthetic cellulosic fibers used in the blends are still inexpensive and comfortable to the wearer. Thus, the benefits of cotton (affordability and comfort) are still attained while a drawback of cotton—low durability—is avoided. In one embodiment, the fiber blend includes FR modacrylic fibers and synthetic cellulosic fibers, preferably, but not necessarily non-FR lyocell fibers such as TENCEL™ and TENCEL A100™. Other fibers may be added to the blend, including, but not limited to, additional types of inherently FR fibers, anti-static fibers, anti-microbial fibers, stretch fibers, and/or high tenacity fibers. The fiber blends disclosed herein may be used to form various types of FR fabrics. Desired colors may be imparted in a variety of ways and with a variety of dyes to the fabrics disclosed herein. Fabrics having the fibers blends disclosed herein can be used to construct the entirety of, or various portions of, a variety of protective garments for protecting the wearer against electrical arc flash and flames, including, but not limited to, coveralls, jumpsuits, shirts, jackets, vests, and trousers.

A wound treatment device comprises a wound surface contacting plug (10) and a cover (24) for covering the wound surface (22) and the plug (10), wherein said plug (10) consists of a flat textile isolating material comprising at least one first surface layer (12), one second surface layer (14) and one intermediate space (18) arranged between said surface layers (12, 14). At least the first surface layer (12) is provided with a biocompatible surface and a structure which enables a liquid to pass and prevents a wound tissue from growing in said structure. The intermediate space (18) is provided with isolating threads (16) elastically holding the first surface layer (12) and the second surface layer at a certain distance from each other.

An article, such as a tissue bonding article, includes a flexible material, a polymerization initiator or rate modifier disposed in or on the flexible material, and a polymerizable adhesive composition permeated throughout at least a portion of the flexible material, where the polymerization initiator or rate modifier is a polymerization initiator or rate modifier for the polymerizable adhesive composition.

A fabric is provided that includes a knit structure having a geometric shape imparting an auxetic property to the fabric due to rotation of one or more portions of the knit structure. In some aspects, the fabric includes a knit structure having a triangular lattice shape that imparts an auxetic property to the fabric.

Disclosed herein are color change laminate materials suitable for a variety of uses. The color change laminate materials include at least two layers of extensible materials having visually distinct coloration, and indicate a stretched or extended state by exposing the previously covered coloration of a lower layer. The color change laminate materials may also indicate the amount of stretching or extension is applied to the laminate. When the laminate includes elastic materials capable of stretch and recovery, the color change laminate materials may further be reversible color change laminate materials that can display color change upon extension and then recover the extension and return to the original coloration. Such color change laminate materials and reversible color change laminate materials are highly useful for use in garments or other textile type applications, in or on personal care products, protective wear products, health care and medical care products, bandages and the like.
