Abstract

A graphene sea-island fiber and a manufacturing method thereof, comprising the steps of: preparing a graphene masterbatch from a graphene functional material through esterification polymerization, blending with PET and melting to obtain a graphene island component; making the graphene island Components are melt blended with soluble polyester sea components to obtain graphene islands-in-the-sea filaments, and then the graphene islands-in-the-sea fibers are obtained through processes such as bundling, drawing, tension heat setting, crimping, oiling, relaxation heat setting, and cutting. The graphene sea-island fiber of the present invention can reduce the surface resistivity of the material, can quickly release the generated static charge, and at the same time endow the material surface with a certain degree of lubricity, further reducing the friction coefficient, thereby inhibiting and reducing the generation of static charge; biocompatible It is a non-toxic, green and efficient functional textile, which has the far-infrared, antibacterial, antibacterial and antistatic functions 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...
