Use black carbon inside conductive nylon filaments 20D/3F(ourter ring type) cover common black(white) polyester DTY(FDY) filaments 50D/75D/100D/150D/200D by S direction only. Use black carbon inside conductive nylon filaments 20D/3F(ourter ring type) cover common black(white) polyester DTY(FDY) filaments 50D/75D/100D/150D/200D by S direction and Z direction concurrently. c) Could keep ability of electro static discharge after 250 times washing? Of course, so long as this materials exists in, it always has this capacity of electro static discharge.
