An item may include fabric or other materials formed from intertwined strands of material. The item may include circuitry that produces signals. The strands of material may include non-conductive strands and conductive strands. The conductive strands may carry the signals produced by the circuitry. Each conductive strand may have a strand core, a conductive coating on the strand core, and an insulating layer on the conductive coating. The strand cores may be strands formed from polymer. The conductive coating may be formed from metal. Electrical connections may be made between intertwined conductive strands by selectively removing portions of the outer insulating layer to expose the conductive cores of overlapping conductive strands. A conductive material such as solder or conductive epoxy may be applied to the exposed portions of the conductive cores to electrically and mechanically connect the overlapping conductive strands.

A method of manufacturing a cover for a vehicle seat by weaving a first layer including a synthetic material, weaving a second layer including wool, and interweaving the first layer and the second layer with the second layer underling the first layer. The cover may include a woven top layer and a woven bottom layer, interwoven with the woven top layer. The woven top layer may include a plurality of first warp yarns and a plurality of first weft yarns. The woven bottom layer may include a plurality of second warp yarns and a plurality of second weft yarns. The plurality of second warp and weft yarns may include wool.

An apparatus for fabrication of a woven tubular nanotextile used in vascular graft applications. The woven nanotextile conduit is 0.1 to 50 mm in diameter and includes a multitude of hierarchically arranged nanofibers. They are made from low strength bundled nanoyarns containing thousands of nanofibers with improved mechanical strength. The weaving apparatus interweaves the warp and weft yarns in longitudinal and transverse directions, resulting in a flexible and strong woven product. The physical and biological properties of the woven nanotextile were significantly enhanced when compared to non-woven nanofibrous form and conventional medical textiles. The nanotextile displayed superhydrophilic behavior in an otherwise hydrophobic material and when implanted as a vascular graft was robust, suturable, kink-proof and non-thrombogenic, with complete endothelialization of the graft luminal area.

A tubular woven fabric is useful as a transport hose for a fluid or a powder, as a protective hose for linear bodies such as wires, cables and conduits, as a tubular filter, or as a base material of a vascular prosthesis. The tubular woven fabric includes warp yarns and weft yarns interwoven with each other, the tubular woven fabric having an outer diameter with a variation of within 10% along the warp direction and satisfying the formula:

(L2L1)/L10.1.

Shape memory yarns described herein include twisted microfilaments made from a shape memory alloy that may provide superelastic or shape memory properties. The shape memory yarns are formed into coils that provide a high degree of actuation or elasticity along an axis of the coiled shape memory yarn, and may have relatively low porosity, low rigidity, and/or low change of volume compared to shape memory coils formed from solid structures. Coiled shape memory yarns may provide further tailorability of a superelastic or shape memory response of a system or device incorporating the coiled shape memory yarns through various coil parameters, such as coil pitch or density, or torque balancing, such as heat treating or plying the coiled shape memory yarns.
