Problems solved by technology

[0004] The processing of polyester needs to be carried out at high temperature (200°C or higher). Many known flame retardants are not suitable for adding to spinning in polyester
Certain organophosphorus flame retardant compounds, such as phosphate esters, may act as plasticizers, but result in a decrease in the breaking strength of the fibers
Compounds such as some phosphates are relatively unstable to hydrolysis, which may lead to the formation of undesired polyphosphate compounds

Abstract

The invention relates to the field of production of synthetic fibers, in particular to a method of manufacturing biomass graphene flame-retardant polyester fiber that is prepared from biomass graphene flame-retardant functional material by means of esterification and polymerization spinning. The biomass graphene flame-retardant polyester fiber can reduce surface resistivity and discharge produced static charge quickly, certain lubrication is provided for the surface of a material, friction coefficient is reduced, static charge is thereby inhibited and reduced, good biocompatibility is provided, the fiber does not contain or produce chemical matters and components harmful to human bodies, and functional textile fabric nontoxic, green and efficient is produced; the fabric has unique metal gloss, is free of chemical dyeing and finishing, has naturally lasting color, and is as functional as the flame-retardant graphene fiber in far-infrared effect, antibacterial effect and antistatic effect.

Description

Technical field [0001] The invention relates to the technical field of synthetic fiber production, in particular to a manufacturing method of biomass graphene flame-retardant polyester fiber. Background technique [0002] With the development of economy, people's requirements for flame retardant textiles are increasing day by day. Because most textiles are flammable, especially polyester fibers, which occupy the largest amount, are combustible, which has become one of the main factors causing fires. Therefore, the development of flame-retardant polyester fibers is particularly important. [0003] The realization of the flame retardant function of polyester fiber depends on adding flame retardant to the fiber. The flame retardants currently used mainly include halogen, bromine, phosphorus, nitrogen, aluminum-magnesium, nano-clay, and intumescent flame retardants. Among them, aluminum-magnesium-based flame retardants have become the mainstay of the market as inexpensive flame-retar...
