Electroconductive carbon fiber production technology

Abstract

The invention discloses an electroconductive carbon fiber production technology. An electroconductive carbon fiber consists of an inner layer and an outer layer, wherein the section of the inner layer is in a three-leaf shape, the cylindrical outer layer wraps the inner layer, the inner layer comprises, by mass, 80-150 parts of polyamide-6, and the outer layer comprises, by mass, 40-80 parts of polyamide-6, 6-12 parts of carbon black, 1-3 parts of graphene powder and 0.1-1 part of titanium dioxide. The electroconductive carbon fiber production technology has the advantages that the inner layer and the outer layer of the electroconductive carbon fiber are replaceable; with the carbon black and the graphene powder added for improving fiber performance, the electroconductive carbon fiber not only is of high strength, high elasticity and high resistance to wear and weather as same as common polyamide fibers, but also overcomes the defect that the polyamide fibers are prone to generation and accumulation of static electricity, thereby being excellent in antistatic performance, endowing people with better wearing experience and being applicable to flammable and combustible occasions.

Description

[0001] 【Technical field】 [0002] The invention relates to a spinning process, in particular to a production process of conductive carbon fibers. [0003] 【Background technique】 [0004] At present, synthetic fibers generally include polyester (polyester), nylon (polyamide), polypropylene (polypropylene), spandex (polyurethane), acrylic (polyacrylonitrile) and the like. These fibers have different properties and thus different uses. But at present generally take fabric, because its fiber is thicker, feel rough, softness is poor, air permeability is poor, water absorption is poor, easy to pilling. With the improvement of people's living standards, the requirements for textiles are getting higher and higher. Polyamide fiber is the earliest synthetic fiber variety put into industrial production in the world, among which polycaprolactone amide fiber (Nylon6, nylon 6, polyamide 6) and polyhexamethylene adipamide fiber (Nylon66, nylon 66, polyamide 66) has the largest output and t...
