Included are multiple component elastic fibers prepared by a solution-spinning process such as dry spinning or wet spinner of spandex fibers including polyurethaneurea and polyurethane compositions. These fibers have a cross-section including at least two separate regions with definable boundaries wherein at least one region defined by the boundaries of the cross-section includes a polyurethaneurea or polyurethane composition. One region of the fiber includes a fusibility improvement additive to enhance adhesion to itself or to a substrate.

Weaving equipment may include warp strand positioning equipment that positions warp strands and weft strand positioning equipment that inserts weft strands among the warp strands to form fabric. The fabric may include insulating strands and conductive strands. The conductive strands may be coupled to electrical components. The warp strand positioning equipment may position the warp strands to form a shed. Component insertion equipment may be used to insert electrical components into the shed. The weaving equipment may have a reed. The reed may be used to help position an electrical component in the fabric. The weaving equipment may have take-down equipment and individually controllable warp fiber positioning and tensioning devices.

The present invention discloses a fabric woven by imitating warp knitting, which includes first warps, second warps, first wefts, and second wefts; the first warps and the first wefts are interlaced to form the face of the fabric, and the second warps and the second wefts are interlaced to form the back of the fabric; and 7 to 15 weft interlacing points are arranged between each two adjacent groups of warp interlacing points on the second warps. The fabric woven by imitating warp knitting in the present invention has not only the appearance style of woven fabrics but also the characteristics of good air permeability and good hand feel of warp-knitted fabrics.

A woven terrycloth stretch fabric includes: weft yarns arranged along a first direction; first and second ground warp yarns arranged along a second direction, the first and second ground warp yarns being looped around the weft yarns with a first degree of tightness. Face loop warp yarns and back loop warp yarns are looped around the weft yarns with a second lesser degree of tightness, the ground warp yarns together with the weft yarns, together forming a base ground of the terrycloth stretch fabric. The plurality of face loop warp yarns and the plurality of back loop warp yarns each loop around the weft yarns so as to form front and back piles of the terrycloth stretch fabric. At least one of the ground warp yarns has a composite yarn comprising a cotton yarn having a polyolefin-based elastic yarn core.

This invention relates generally to flexible materials, especially those made of carbon fiber. The materials exhibit a first flexural modulus over a first range of flexural strain and a second flexural modulus over a second range of flexural strain. The materials provide advantages when used in an article of manufacture in which the performance may be improved by having a different flexural modulus depending on the amount of flexural strain, and thus dislocation, of the material.
