Abstract

The invention relates to the field of production of synthetic fibers and particularly provides a hollowed biomass graphene polyester fiber. A manufacturing method of the hollowed biomass graphene polyester fiber includes the steps of: drying biomass graphene master batches and polyester chips, spinning the materials on a profiled spinneret, and performing drafting process to produce the biomass graphene polyester fibers with hollowed cross section. A fabric woven from the fibers has the functions of odor adsorption, far-infrared ray, bacterial resistant and inhibiting, anti-static effect of graphene fiber and warm-keeping and fluffiness of the hollowed fibers. The fabric has good bioavailability, and is free of and does not generate harmful chemical substances and components, and is a toxic-free, green and high-effective functional fabric.

Description

technical field [0001] The invention relates to the technical field of synthetic fiber production, in particular to a method for manufacturing hollow biomass graphene polyester fibers. Background technique [0002] Graphene is a new type of carbon nano light material, which has a unique monoatomic layer two-dimensional crystal structure, high specific surface area, high strength, electrical conductivity, thermal conductivity, high absorption efficiency of various types of light, and ideal shielding effect . Graphene is known as "the magical material that will change the 21st century". With the gradual maturity and improvement of related technologies in the application field of graphene, such unimaginable things as mobile phone screens can be bent arbitrarily, electric vehicles can be charged instantly, and computer screens are as transparent and thin as white paper. become a reality. On November 30, 2015, the Ministry of Industry and Information Technology, the National De...
