Abstract

The invention discloses a high-conductivity wool top fiber. The high-conductivity wool top fiber comprises an inner layer and an outer layer, wherein the cross section of the inner layer is triangular, the outer layer wraps the outer circumference of the inner layer, and the cross section of the outer layer is circular; the inner layer is prepared from, by weight, 65-75 parts of polyamide-6, 15-22parts of poly-p-benzoyl hexamethylenediamine, 10-14 parts of an elastomer, 4.5-6.5 parts of graphene, 6-10 part of carbon black and 6.5-10.5 parts of a nanofiller; the outer layer is prepared from 6-100 parts of polyamide by weight. The high-conductivity wool top fiber is formed by finely selecting raw materials, and the contents of various raw materials are optimized, so that the prepared high-conductivity wool top fiber has low volume resistivity, good electrical conductivity, long-lasting electrical conductivity and good antistatic performance, the high-conductivity wool top fiber also hasthe advantages of soft hand feeling, elasticity, higher strength, good wear resistance and weather resistance and the like, and therefore, the high-conductivity wool top fiber is suitable for being prepared into various conductive fabrics, is comfortable to wear, and is especially suitable for places sensitive to static electricity.

Description

technical field [0001] The invention relates to the field of functional fiber products, in particular to a high-conductivity top fiber and a preparation method thereof. Background technique [0002] With the development of industrial production, accidents caused by static electricity are increasing day by day, so the role and harm of static electricity have been valued by research institutions and academic organizations in various countries. [0003] In recent years, with the rapid development and popularization of computers, telecommunications, microwave ovens, etc., electromagnetic radiation in human living and working environments has become increasingly serious, and the resulting electromagnetic wave interference has brought many negative effects to the normal operation of electronic equipment and human health. influences. In order to prevent electrostatic interference and electromagnetic wave interference, various antistatic products and electromagnetic shielding mater...
