Abstract

The invention discloses a carrier dyeing process of polybutylene succinate fibers, which adopts disperse dyes to carry out low-temperature carrier dyeing on the polybutylene succinate fibers, therebysolving the problem that common dyeing of the polybutylene succinate fibers causes low dye uptake. The carrier dyeing process comprises the steps of: (1) removing impurities attached to the surface ofpolybutylene succinate fibers, and drying; (2) adding the polybutylene succinate fibers which are washed to remove impurities into a dye liquor containing a low-temperature disperse dye and a carrier, and carrying out dyeing; and (3) performing reduction cleaning on the polybutylene succinate fibers dyed.

Description

technical field [0001] The invention belongs to the field of textile dyeing processing, and in particular 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 biodegradability. 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 polyethylene. Compared with polylactate (PLA) and polyhydroxybutyrate (PHA), polybutylene succinate fiber is cheap, has better heat resistance, mechanical properties and softness, and is easy to process and shape , so that the industrial production of polybutylene succinate fiber has certain research value. At present, few people at home and abroad have conducted research on the dyeing and finishing ...
