ELECTRIC HEATING FABRIC Russian patent published in 1998 - IPC

FIELD: textile industry, in particular, specialized woven articles; may be used in development of electric heating devices of industrial and domestic applications with use of independent low-voltage DC sources. SUBSTANCE: electric heating fabric has background part formed by weave of dielectric warp and weft threads and electric conducting threads. The latter form within fabric background part groups from m parallel electric conducting threads. In each group adjacent conducting threads are located at preset distance b from one another selected from the conditions of heat balance of medium surrounding the electric heating fabric during its functioning. Groups of conducting threads form parallel sections separated from one another by insulating strips. EFFECT: higher efficiency. 12 cl, 4 dwg
