Abstract

The invention discloses a bicomponent fiber of polylactic acid and polyethylene butanediol succinate, which is characterized in that the polylactic acid and the polyethylene butanediol succinate are firstly obtained by polymerization; the two different polymers are respectively melted in the process of spinning silk and are combined into a single fiber in the last moment before extrusion to obtain a degradable fiber with puffing performance.

Description

technical field

[0001] The invention relates to the field of fiber preparation, in particular to a poly(lactic acid polybutylene succinate) bicomponent fiber. Background technique

[0002] As people pay more and more attention to environmental protection, biodegradable polymer materials (plastics, rubber, fibers, etc.) have become a research hotspot in countries all over the world. There are more and more types of degradable fibers, and their applications involve many fields such as medical, clothing, fishery, construction, sanitation, decoration, and industrial processing. Through research, it is found that the biodegradability of aromatic polyesters containing benzene rings in the main polymer chain is poor, while the biodegradability of aliphatic polyesters synthesized from dibasic acids and dibasic alcohols, hydroxy acids or lactides is relatively poor. Well, among them, polylactic acid and polybutylene succinate have a melting point higher than 100°C, have application ...
