The invention discloses an anti-static stretch covering
yarn which comprises spandex stretch yarns, chinlon high stretch yarns and
polyester low stretch yarns, the chinlon high stretch yarns and the
polyester low stretch yarns are wound on the outer portions of the spandex stretch yarns in a crossing mode to form the covering
yarn, anti-static additives are arranged in the chinlon high stretch yarns and the
polyester low stretch yarns respectively, the anti-static additives added in the chinlon high stretch yarns account for, by weight, 2 percent to 3 percent, and the anti-static additives added in the polyester low stretch yarns account for, by weight, 2.5 percent to 3.5 percent. According to the anti-static elastic covering
yarn, the anti-static additives are contained in the chinlon high stretch yarns and the polyester low stretch yarns on the surface of the covering yarn, static is restrained in the producing and using process, and the anti-static elastic covering yarn is high in safety performance, good in stretch, high in comfort level and wide in application range.
