    Abstract: Strands of material may be intertwined using weaving techniques, knitting techniques, non-woven or entanglement techniques, or braiding techniques. Fabric that is formed from the strands of material may be used in forming a fabric-based item. The fabric based item may include electrical components. The strands may include conductive strands that form signal paths. The signal paths can carry electrical signals associated with operation of the electrical components. Each strand may have an elongated core and a coating. Strands may also include intermediate layers between the cores and coatings. The cores, intermediate layers, and coatings may be formed from polymer without conductive filler, polymer with conductive filler, and/or metal. A polymer core may be provided with recesses to help retain subsequently deposited layers such as a metal coating layer. The recesses may be grooves that extend along the longitudinal axis of the core.

    Abstract: An item may include fabric or other materials formed from intertwined strands of material. The strands of material may include non-conductive strands and conductive strands. The strands may be intertwined by a warp knitting machine to produce a warp knit fabric. The warp knit fabric may include intertwined warp strands and weft insertion strands that are inserted amongst the warp strands. The weft insertion strands may extend across less than all of the warp strands. The weft insertion strands may include parallel segments that each extend across a different portion of the warp strands. The segments of weft insertion strands may have different widths relative to one another and relative to the width of the fabric. The weft insertion strands may be inserted into the warp knitting machine across the warp strands using a weft insertion device that is positioned by a computer-controlled positioner.

    Abstract: 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. Conductive strands may run orthogonal to each other and may cross at open circuit and short circuit intersections. The fabric may be formed using pairs of interwoven warp and weft strands. Conductive warp and weft strands may be interposed within the pairs of strands. The fabric may be a single layer fabric or may contain two or more layers. Stacked warp strands may be formed between pairs of adjacent insulating warp strands. The stacked warp strands may include insulating and conductive strands. Touch sensors and other components may include conductive structures that are formed from the conductive strands in the fabric.

    Abstract: A fabric-based item may include fabric formed from intertwined strands of material. The fabric may include first and second fabric layers that at least partially surround a pocket. Initially, the pocket may be completely enclosed by the first and second layers of fabric. A shim may be placed in the pocket before the pocket is closed. An opening may be formed in the first layer of fabric to expose a conductive strand in the pocket. The shim may prevent the cutting tool from cutting all the way through to the second layer of fabric. After cutting the hole in the first layer of fabric, the shim may be removed and an electrical component may be soldered to the conductive strand in the pocket. A polymer material may be injected into the pocket to encapsulate the electrical component. The polymer material may interlock with the surrounding pocket walls.
