Conductive yarns in a knitted fabric may include insulating cores covered with metal layers that form signal paths. Open circuits may be formed in the yarns by removing metal from the insulating cores at selected locations within the yarns. The fabric may be formed from rows of interlocked loops of the yarn. The open circuits may be located on the loops so that each loop with an open circuit has a first segment of the metal layer that is separated from a second segment of the layer by a portion of the loop from which the metal layer has been removed. Each electrical component may have terminals that span a respective one of the open circuits and that are shorted respectively to the metal of the first and second segments.

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.

The invention relates to a fabric. The fabric (10) comprises, in the fabric material, threads (11a1,12a1;13a1,14a1) of a material conducting electricity well, by means of which electro-magnetic radiation and magnetic fields are filtered. The threads (11a1,12a1;13a1,14a1) are placed next to each other. Furthermore, the threads are wound around their winding axes (X1,X2;Y1,Y2) so that the first thread (11a1, 13a1) in the fabric is wound clockwise, and the second thread (12a1, 14a1) next to it is wound counterclockwise.

Systems and methods are provided for detecting liquid in a textile article using one or more flexible sensors integrated in the textile article. The sensor data is forwarded to a computing device via a communication link by an interface element associated with the textile article. The computing device detects a location of liquid in the textile article proximate to the one or more flexible sensors based on a determination that a criterion is met.

The invention discloses a free cut fabric being not prone to edge curling, including a fabric body, wherein the fabric body comprises a plurality of first yarns and second yarns which are interwoven with each other, each first yarn is laid into a loop in turns by every other needle, so that the warp knitted stitch structure formed by weaving the first yarns is a cord stitch; a link of the cord stitch spans two needle pitches, and the cord stitch serves as a top stitch; and each second yarn is simultaneously laid on two adjacent knitting needles and woven into a loop, so that the warp knitted stitch structure formed by weaving the second yarns is a double loop stitch, the double loop stitch serves as a ground stitch. The invention can effectively avoid curling and loosening phenomena in the cutting process, and has high use comfort.

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.
