Abstract

The invention relates to a graphene island fiber and a manufacturing method thereof. The manufacturing method comprises the following steps of preparing graphene master batch from a functional graphene material through esterification polymerization, and then blending and melting the graphene master batch and PET to obtain a graphene island composition; melting and blending the graphene island composition and a soluble polyester marine composition to obtain graphene island protofilaments, and conducting working processes of bundling, drafting, tension heat setting, curling, oiling, relaxation heat setting, cutting and the like to obtain the graphene island fiber. The graphene island fiber can reduce the surface resistivity of a material, quickly release generated electrostatic charge, endowthe surface of the material with certain lubricity at the same time and further reduce the friction coefficient so as to inhibit and reduce the generation of electrostatic charge. The biocompatibility is high, and the graphene island fiber is a non-toxic, environment-friendly and efficient functional textile and has the far infrared function, antibacterial function, bacteriostatic function and antistatic function of graphene fibers.

Description

technical field [0001] The invention belongs to the technical field of synthetic fiber production, and in particular relates to a graphene sea-island fiber and a manufacturing method thereof. Background technique [0002] With the development of economy and social life, people's requirements for multifunctional textiles are increasing day by day, especially non-toxic, green, far infrared, antibacterial and antibacterial, antistatic, with unique metallic luster, no chemical dyeing and finishing, natural and lasting color There is a strong demand for textiles with other functions. The sea-island composite fiber fabric feels soft and smooth, and can be made into a fabric with high density, hygroscopicity, water repellency, and unique aesthetics and fashion style; the sea-island composite fiber has a small linear density and a large fiber specific surface area. High coverage, bulkiness, warmth retention and adsorption, which make the fabric have strong dust absorption, decontam...
