Abstract

The utility model discloses an antistatic sewing thread, relates to the technical field of sewing threads, and aims to solve the problem that the sewing thread is easy to loosen. According to the key points of the technical scheme, the anti-static fabric comprises a core layer and a wrapping layer, an anti-static layer is arranged between the wrapping layer and the core layer, the core layer is formed by twisting elastic fibers, the anti-static layer comprises anti-static yarn and moisture absorption expansion yarn which are mutually twisted, and the anti-static yarn and the moisture absorption expansion yarn are wound on the outer side of the core layer in an S twist mode. The wrapping layer wraps the outer sides of the anti-static yarn and the moisture absorption expansion yarn. The wrapping layer wraps the outer sides of the anti-static yarn and the moisture absorption expansion yarn, the wrapping layer is arranged on the outermost side, the core layer and the anti-static layer can be wrapped, the sewing thread is prevented from loosening in the using process, the moisture absorption expansion yarn can expand after absorbing moisture, and therefore the anti-static yarn and the moisture absorption expansion yarn are connected more tightly, and the anti-static performance of the sewing thread is improved. And the situation that the sewing thread is loosened in the using process is prevented.
