Abstract

A high-strength high-modulus graphene/nylon-6 fiber and a preparation method thereof are provided. The fiber is obtained through processing modified graphene and caprolactam with in situ polymerization and high-speed melt spinning. A graphene/nylon-6 composite is provided, which is obtained through compositing the modified graphene, the caprolactam and an additive. Based on the composite, a graphene/nylon-6 fabric with a permanent far-infrared healthcare function and a graphene/nylon-6 fabric with an ultraviolet protective property are provided, whose far-infrared property and ultraviolet protective property will not be attenuated due to an increase of fabric washing times, having a great market potential.
