Graphene conductive polyester fiber and preparation method thereof

Abstract

The invention discloses a polyester conductive fiber. The purpose of the invention is to provide a graphene conductive polyester fiber with good conductivity and long-lasting antistatic properties and a preparation method thereof; Chemical treatment, the size of graphene particles is less than 1 micron, and the dispersion is good. According to the mass ratio of 1-5:1-5:1-5:1, graphene, carbon nanotubes, and surfactants are stirred, mixed, and dispersed to obtain Conductive particles; add conductive particles to polyester powder, and use twin-screw granulation process to prepare graphene superconducting masterbatch; spinning technology steps adopt two-component composite spinning technology or one-component blending spinning technology to produce The graphene conductive polyester fiber is obtained; the invention has the characteristics of simple production process, low energy consumption, labor saving, suitable for mass production and the like.

Description

technical field [0001] The invention relates to polyester conductive fibers, in particular to graphene conductive polyester fibers used in antistatic, dustproof and antibacterial work clothes, military explosion-proof clothes, high-grade suit fabrics, carpets and the like. Background technique [0002] Polyester fiber is currently the most produced chemical fiber variety at home and abroad, especially with the development of new synthetic fibers with new functions, its production and usage have increased sharply, and its application fields have continued to expand. However, due to the hydrophobicity of polyester fibers, fibers and their products are prone to static electricity due to friction or being stretched, compressed, and induced in a dry electric field. The material is comfortable to wear. At the same time, as decorative fabrics such as carpets and curtains, there are also electrostatic interferences. In scientific research and industrial production such as electroni...

Problems solved by technology

However, due to the hydrophobicity of polyester fibers, fibers and their products are prone to static electricity due to friction or being stretched, compressed, and induced in a dry electric field. Material comfort

At the same time, as decorative fabrics such as carpets and curtains, there are also electrostatic interferences. In scientific research and industrial production such as electronics, petroleum, and national defense, static electricity sometimes causes failures and vicious accidents.

At present, there is no report on the preparation of graphene conductive polyester fiber by the two-component composite spinning technology and the single-component blend spinning technology of graphene.
