HEATING FABRIC WITH ELECTRICALLY CONDUCTIVE WEFT THREADS

摘要

An electrical heating fabric has a warp composed of non-conductive threads, and selvedges which include plural lead wires. In the weft direction the fabric has both non-conductive threads and conductive wires. The different types of weft material are arranged in successive strips disposed transversely to the warp. First strips have non-conductive weft threads only. Second strips additionally have conductive weft wires. The strips are arranged alternately. The weft wires are all discrete, and their two ends are either in simple contact with the selvedge lead wires or are interwoven therewith.
