Abstract

The invention discloses a polyester fiber dyeing carrier and a preparation method thereof. The synthesis process of the carrier is simple, a dyeing accelerating effect is obtain by using environmental-friendly solvent to dye polyester fibers, and the production process is reduced because the solvent is not required to be recovered; the carrier is nontoxic, tasteless and biodegradable, colored spots are not caused during use and the fabric is odorless; and the carrier can also be used for normal-pressure low-temperature (95-110DEG C) dyeing of polyester fiber fabrics, the dyeing temperature of the polyester fiber fabrics is decreased, the color yield is high, the requirement on dyeing equipment is low and the large-scale production can be realized.

Description

technical field [0001] The invention relates to the field of a polyester dyeing carrier, in particular to an environment-friendly polyester dyeing carrier and a preparation method thereof. Background technique [0002] Polyester fiber has excellent performance and has a wide range of application fields. Its excellent performance makes it one of the fastest growing and highest-yielding varieties of synthetic fibers. Due to the high degree of crystallinity, orientation and glass transition temperature of polyester fibers, the molecular structure lacks active groups that can combine with dyes like cellulose or protein fibers. Small gaps, so polyester has high requirements for dyeing conditions. Usually, it needs to be dyed by high temperature and high pressure method (120℃~130℃) or hot melt method (180℃~220℃). Only under high temperature conditions, the fiber molecular chain movement Intensified, larger pores are formed in an instant, and the dye molecules can enter the interi...
