Spacer fabric for use as e.g. seat heating mat in motor vehicle, has individual electrically conductive resistor wire that is attached at one of poles of electrical voltage supply and comprises electrical insulating layer over entire length

摘要

The fabric has upper and lower cover layers (1, 2) held at a distance by bending resistant and bending elastic threads i.e. warp threads (3), of defined length by forming an intermediate layer. An individual electrically conductive resistor wire i.e. power strand, is inserted and moved back and froth into a heating zone during knitting of fabric continuously according to type of filling thread in the intermediate layer in a meander-shaped knitting direction. The wire is attached at one of poles of an electrical voltage supply and has an electrical insulating layer provided over entire length. An independent claim is also included for a knitting machine comprising a thread guide.
