CURRENT CONDUCTING HEAT-RESISTANT CLOTH Russian patent published in 1996 - IPC

FIELD: tailoring industry. SUBSTANCE: cloth is made with transparent weave and surface porosity of 50-65%. Cloth warp and weft are made of composite thread which consists of polyaramide complex thread twisted with copper wire coated with nickel. Twisting of composite thread has 350-400 twists per meter, linear density is of 90-120 tex. Cloth warp density is 16-20 threads per centimeter, weft density is 10-20 threads per centimeter. Composite thread consists of complex polyaramide thread with linear density of 14.3-58 tex, with twisting of 100-200 twists per meter, and copper wire coated with nickel and 7-120 mcm in diameter. Copper wire-to-polyaramide thread ratio is (50-70):(50-30). EFFECT: higher efficiency. 1 tbl
