Problems solved by technology

However, almost all research results show that the single fiber length of these new fibers is even less than 1cm, which is far from the minimum requirement of traditional spinning for fiber length.
Currently commonly used biomass fibers have high brittleness, poor mechanical properties, and poor hygroscopicity, which limit industrial applications.

Abstract

The invention discloses a biopolymer fiber and a processing technology thereof. The biopolymer fiber is prepared from biopolymer polyester chips and cellulose nanocrystals by blend melt spinning. Interaction of biopolymer polyester chip molecules is enhanced by association hydrogen bonds formed among the cellulose nanocrystals and the biopolymer polyester chips, connecting bridges among biopolymerpolyester chip macromolecules are formed, relative slip of biopolymer polyester chip macromolecular chains is inhibited, so that the breaking strength of the biopolymer fiber is improved. As bio-based mixed polyols contain a large quantity of hydroxide radicals, hydrophilic groups are introduced into the prepared biopolymer polyester chip macromolecular chains, the hydrophilic performance of thebiopolymer polyester chips is improved, and hygroscopicity of the biopolymer fiber is improved. Experimental results indicate that the prepared biopolymer fiber has higher breaking strength, good toughness and mechanical performance and excellent hygroscopicity.

Description

technical field [0001] The invention relates to the technical field of biomass fibers, in particular to a biomass fiber and a processing technology thereof. Background technique [0002] China is the largest producer of chemical fiber in the world. The development of chemical fiber has been strong in recent years. However, more than 90% of the growth of the chemical fiber industry depends on limited and non-renewable petroleum resources. The raw material for synthetic chemical fiber polyester chips is ethylene glycol. Alcohol and ethylene glycol are basically derived from petroleum industry products, while petroleum resources are decreasing day by day, the contradiction between oil supply and demand is increasing day by day, and the war for oil is intensifying. The whole world is working hard to research and explore the inexhaustible biological resources on the earth. Using renewable biomass resources to develop bio-based chemical industry and replace petrochemical products...
