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.

A composite spacer fabric comprises an outer flat warp-knitted fabric layer having openings each formed by a respective plurality of stitches and an inner flat warp-knitted fabric layer also having openings that are each formed by a respective plurality of stitches. The second warp-knitted fabric layer further has at least a first and a second yarn system. The yarns of the first yarn system run in a production direction on exactly one respective stitch wale and the yarns of the second yarn system extend over at least two adjacent stitch wales that run in the production direction. Spacer yarns interconnect the warp-knitted fabric layers.

A knitted spacer fabric has a first warp-knitted layer having wales running in a production direction and rows of stitches extending in a transverse direction, a second warp-knitted layer also having wales running in a production direction and rows of stitches extending in a transverse direction. Spacer yarns connect the knitted layers, and at least one of the knitted layers are composed of nonconductive yarns and conductive yarns. The conductive yarns are incorporated into the one knitted layer in some areas in a functional region extending in a production direction and resting on the respective knitted layer in a connection region that extends over a plurality of rows of stitches as a float stitch.

A knitted spacer fabric has a tightly knitted bottom layer, a more loosely knitted upper layer and linking fibres extending across the space between the lower and upper faces. Settable material, e.g. cement, is introduced into the space between the upper and lower faces and can be caused to set by the addition of a liquid, e.g. water. Until set, the fabric is flexible and can be shaped but after the material in space has set, the fabric is rigid and can be used as a structural element in a wide range of situations. The bottom layer has an extension that extends beyond the upper face and is connected to the upper face by elastic connecting fibres that draw the extension towards the other face, thereby at least partly closing the space at the edge of the cloth and preventing the settable material from spilling out. In addition, the packing of the settable material and maximum space between the faces are such that only a predetermined amount of liquid can be accommodated within the space and that amount is matched to the water required to set the cement.

A spacer fabric has two textile layers and spacer yarns that transversely connect the textile layers and where the yarns forming the textile layers are composed exclusively of a nonmetallic material. In addition, at least a first portion of the spacer yarns is composed of metallic yarn, and a weight of all metallic spacer yarns is between 40 and 96% relative to the total weight of the spacer fabric.

A fabric made of yarns interlooping with each other or passing through an inner layer at looping intervals. The fabric is embossed with a micro-pattern extending into the yarns or into a layer underneath the fabric. The micro-pattern contains a pre-defined pattern of a plurality of binding points attaching the yarns to the inner layer or to the added underlayer. This micro-pattern has an inter-point spacing between adjacent binding points that is less than the interlooping intervals. The fabric can also be embossed with a macro-pattern separate from and coarser than the micro-pattern. The macro-pattern establishes a desired aesthetic in the fabric, and the micro-pattern does not interfere with the desired aesthetic.
