Abstract

The invention discloses an elastic high-conductivity wool top fiber. The elastic high-conductivity wool top fiber comprises an inner layer and an outer layer; the inner layer has a triangular cross section, the outer circumference of the inner layer is coated with the outer layer, and the outer layer has a circular cross-sectional profile; the inner layer is prepared from, by weight, 65-75 parts of polyamide-6 and 30-36 parts of polyether polyurethane elastomers; the outer layer is prepared from, by weight, 60-70 parts of polyamide-6, 15-20 parts of polyparaphenylene hexamethylene diamine, 20-28 parts of elastomers, 3-5 parts of graphene, 6-8 parts of carbon black and 3.5-5.5 parts of nano fillers. The elastic high-conductivity wool top fiber has the advantages of low volume specific resistance, good and long-lasting conductivity, great antistatic property, soft hand feeling, high elasticity and strength, excellent wearing and weather resistance and the like. Therefore, the elastic high-conductivity wool top fiber is suitable for being prepared into various conductive fabrics with high wearing comfort.

Description

Technical field [0001] The invention relates to the field of functional fiber products, in particular to a highly conductive top fiber with elasticity and a preparation method thereof. Background technique [0002] With the development of industrial production, the number of accidents caused by static electricity is increasing, and the effect and harm of static electricity have therefore been paid attention to 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 life and working environment has become more and more serious. The resulting electromagnetic 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, since the middle of the 20th century, p...
