Abstract

The invention discloses a carrier dyeing process for polybutylene succinate fibers. Disperse dyes are used to perform low-temperature carrier dyeing on polybutylene succinate fibers, which solves the problem of polybutylene succinate fibers. The problem of low dye uptake in common dyeing of fibers. The process steps are: (1) removing the impurities attached to the surface of the polybutylene succinate fiber, and drying; (2) adding the polybutylene succinate fiber after washing and removing the impurities into a dispersion containing a low temperature type dispersion material. Dyeing is carried out in the dye solution of the dye and the carrier; (3) the dyed polybutylene succinate fiber is subjected to reduction cleaning.

Description

technical field [0001] The invention belongs to the field of textile dyeing and processing, and particularly relates to a carrier dyeing process for polybutylene succinate fibers. Background technique [0002] Polybutylene succinate (PBS) fiber is a new type of aliphatic polyester fiber with good physical and mechanical properties and biodegradation properties. Its glass transition temperature is around -30 °C, and its heat distortion temperature is close to 100 °C. , the melting point is 114 ° C, the crystallinity is about 40%, and the elongation at break and tensile strength are similar to those of polyethylene. Compared with polylactate (PLA) and polyhydroxybutyrate (PHA), polybutylene succinate fiber is inexpensive, and has good heat resistance, mechanical properties and softness, and is easy to process and form. , so that the industrial production of polybutylene succinate fiber has certain research value. At present, few people at home and abroad have carried out res...
