An elastic multiple component fiber comprising a cross-section, wherein at least a first region of said cross-section comprises a polyurethaneurea composition; and comprising a second region.

Medical constructs with collagen fibers and gelatin and related collagen fibers. The collagen fibers can be derived from extruded soluble dermal collagen and can include a gelatin film attached to the at least one collagen fiber. The gelatin film can include one or more minerals and has a gelatin concentration of between about 0.1% to about 40% weight per volume.

Rip-stop pants include waist and leg portions formed of ripstop fabric having synthetic mechanical-stretch filament yarns interwoven into spun, staple yarns in a ripstop pattern.

Nonwoven textile fabrics in accordance with the present invention are formed primarily of individualized bast fibers substantially free of pectin. The nonwoven fabric can include staple fibers to a lesser extent than the individualized bast fibers. Individualized bast fibers include fibers derived from the flax and hemp plants. The nonwoven textile fabric is formed into a web while in a dry state and subsequently bonded to produce a nonwoven fabric.

An active fibre comprising material activated by an external stimulus, wherein the fibre has a first configuration in an unactivated state, and in response to activation by the external stimulus the fibre adopts a second, increased twist, configuration, relative to the first configuration, and wherein the fibre can reversibly move between the active state and the unactivated state.

A non-coated woven fabric for air bag according to the present invention comprises a synthetic fiber containing 90% by weight or more of Nylon 66, characterized in that crimping rate of warp of the fabric is 10.0 to 13.0% while crimping rate of woof of the fabric is 6.0% or less, relative viscosity of Nylon 66 constituting the synthetic fiber in sulfuric acid is 3.15 to 3.7, the synthetic fiber contains 40 ppm to 200 ppm of phosphorus component and, when dynamic air permeability of the fabric is measured at a maximum pressure of 805 kPa based on ASTM D 6476 under the environment of 20 C.65% RH, biaxial elongation strain hysteresis of the fabric during a transition from increased pressure to reduced pressure at 50 kPa is 0.69% to 1.0%.

A laminated sheet includes a base cloth layer having a porous structure obtained by impregnating a woven fabric, which has a tear strength by a trapezoid method of 150 N or more in the longitudinal direction and 100 N or more in the lateral direction, with a resin composition containing a polyurethane resin and an organic flame retardant, and a skin layer layered on the base cloth layer, and has plural air holes penetrating in the thickness direction.

Protective garments include a flame resistant fabric that is strong and yet has a soft hand. The fabric is made from a combination of filament yarns and spun yarns. The filament yarns and spun yarns are woven together such that the filament yarns are separated by from about 2 to about 5 spun yarns in both the warp direction and the fill direction. The spun yarns may contain polybenzimidazole fibers in combination with other fibers, such as aramid fibers. The filament yarns may comprise para-aramid fibers. In one embodiment, the filament yarns may have a size larger than the spun yarns.

The present invention addresses the problem of providing a cloth which, when used as an air bag main body cloth, does not undergo the damage caused by a high-temperature gas generated from an inflater, and therefore has high heat resistance and is suitable for an air bag. The means for solving the problem is a coated cloth for an air bag, which is produced by applying an elastomer resin layer on at least one surface of a three-dimensional woven fabric in an amount of 50 to 500 g/m.sup.2 per one surface, said coated cloth being characterized by having void spaces formed therein, wherein the void content in the coated cloth is 15 to 60%. Preferably, the coated cloth is used in applications in which the coated cloth is attached onto the periphery of an inflater connection opening in an air bag.

The invention relates to an elastic composite structure, which is intended for use as a flexible, pliable and thin film structure in the manufacture of a 2- or 3-dimensional product, particularly for providing mechanical protection against cutting, puncturing and/or the like. The composite structure comprises firstly an elastomer system (1), which is constituted by at least one PUR- (polyurethane resin), PUD- (polyurethane dispersion), SI- (silicone) based elastomer material and/or the like, and secondly by a mechanically durable reinforcer system (2), such as a fabric, weave or knit structure (2a) made from one or more flexible hybrid yarns, an oriented flake reinforcement structure (2c) made from laminated flakes (y), and/or the like. The invention relates also to an elastic composite structure, which is intended for the above application and which comprises a reinforcement system (2) for reinforcing the same mechanically against cutting, puncturing and/or the like. In this respect, the composite structure's reinforcement system (2) is manufactured as a flake reinforcement composition, consisting of hard organic and/or inorganic components (y) and comprising at least one co-laminated hard polymer layer and an elastomer matrix (2; 2b) applied integrally in contact therewith.
