Yarns and fabrics that include modacrylic fibers are described herein. A yarn and/or fabric may include modacrylic fibers, meta-aramid fibers, anti-static fibers, and optionally para-aramid fibers. In some embodiments, the modacrylic fibers, meta-aramid fibers, and, if present, para-aramid fibers, may each be solution-dyed.

An electromagnetic shielding fabric includes: a non-conductive woven layer including a plurality of non-conductive warp threads and a plurality of non-conductive weft threads, both the non-conductive warp threads and the non-conductive weft threads made of a non-conductive material, and a conductive woven layer including a plurality of conductive warp threads and a plurality of conductive weft threads, both the conductive warp threads and the conductive weft threads at least partially made of an electrically conductive material, where the non-conductive woven layer defines a patterned surface of the fabric and the conductive woven layer defines a grid-like structure, the non-conductive woven layer and the conductive woven layer interwoven together, the fabric includes a plurality of sectors, each sector further includes binding points.

A fabric-based item may include fabric formed from intertwined strands of material with embedded circuitry. The strands of material may be formed from dielectric materials such as polymers. The strands of material may be formed from joined segments of polymer strand material or other material. Each joined segment may contain a potentially distinct circuit. Some joined segments may include one or more conductive lines. The conductive lines may run parallel to each other along the length of the joined segments to form circuit interconnects. Conductive lines may be joined to contact pads on integrated circuits and other embedded components formed from semiconductor dies. Control circuitry formed from the integrated circuits embedded in strands of material in the fabric and other control circuitry may be used to control the circuitry embedded in the fabric.

A biocompatible yarn comprising a conductive elastomeric filament, the conductive elastomeric filament comprising a elastomeric polymer and conductive filler.

A metalized fabric and method for metallization of fabric. The fabric is formed using two threads with different affinities for metallization, but which threads are not metalized prior to forming into the fabric. The threads will typically be woven using an unbalanced weave to provide one side of the fabric with a resultant greater amount of metallization than the other but this is not required. Once the resultant fabric is metalized, it will typically be more suitable for consistent color dying than fabric which was formed from both metalized and unmetallized threads.

A color-changing product includes a fabric and a connection bus disposed along at least a portion of the fabric. The fabric includes a plurality of color-changing fibers. Each of the plurality of color-changing fibers has an electrically conductive core and a coating disposed around and along the electrically conductive core. The coating includes a color-changing pigment. The connection bus has a multi-layer structure including a metallic foil layer and a film layer. The metallic foil layer forms a weld between at least a subset of the plurality of color-changing fibers so that current can flow through the connection bus and into the electrically conductive core of at least the subset of the plurality of color-changing fibers. The film layer at least partially isolates the weld from a surrounding environment.
