Description
Technical Field
The invention belongs to the technical field of textile printing and dyeing, and particularly relates to a PBT fiber/polyamide fiber/silk blended fabric and a one-bath one-step dyeing method thereof.
Background
At present, researches on blended fabrics are mostly focused on the aspects of polyester fibers, nylon fibers, cotton fibers, regenerated cellulose fibers (such as tencel and the like), the advantages of various fibers are fully exerted by adjusting different blending proportions, and the advantages are made up for the deficiencies, so that the weaving and wearing performances of the fabrics are greatly improved.
The PBT fiber is a polybutylene terephthalate fiber, which is a polyester fiber prepared by esterification or ester exchange of terephthalic acid (PTA) or dimethyl terephthalate (DMT) and 1, 4-Butanediol (BDO), polycondensation to obtain a polymer, and melt spinning. Because the molecular chain contains a conjugated system formed by a polyester-like benzene ring and carboxyl and also contains a methyl chain segment with the length similar to that of nylon, the PBT fiber has various excellent performances of polyamide fiber (nylon fiber) and common polyester fiber (polyester fiber).
Similar to PET fibers (polyester fibers), PBT fibers are dyed with disperse dyes under high temperature (110 to 140 ℃) and acidic conditions as a common dyeing condition, and reduction cleaning is usually required after dyeing (see patent documents 1 to 3).
The nylon fiber has the characteristics of softness, wear resistance, comfort and cool feeling.
The silk is the lightest, softest and finest natural fiber in the nature, is known as 'fiber queen', but has high price and exists as top luxury goods since ancient times.
However, polyamide fiber and silk have poor homochromatism and are prone to cause uneven coloring, and patent document 4 adopts a two-bath method to solve the technical problem.
At present, no literature report on the PBT fiber/nylon fiber/silk blended fabric and the dyeing method thereof is found.
