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.
