Abstract

The invention discloses a PBT fiber / nylon fiber / silk blended fabric and a one-bath one-step dyeing method thereof. The blended fabric is formed by weaving PBT fiber / nylon fiber / silk blended yarn, andin the blended yarn, a blending ratio of PBT fiber to nylon fiber to silk is (50-70%):(20-40%):10%. One-bath one-step dyeing refers to immersing a blended fabric in dye liquor of disperse dyes, acid dyes, a dispersing agent, a leveling and dispersing agent and a silk low-temperature accelerating agent, adjusting the pH to be 4.5-5.5, raising the temperature to 50-70 DEG C for operating for 5-10 min, and then raising the temperature to 95-98 DEG C for dyeing for 20-40 min. The PBT fiber / nylon fiber / silk blended fabric not only has a smooth handfeel of silk, but also has a good elasticity, meanwhile is slightly cool and comfortable to wear and meets the requirements of customers for high-end fabrics.

Description

technical field [0001] The invention belongs to the technical field of textile printing and dyeing, and in particular relates to a PBT fiber / nylon fiber / silk blended fabric and a one-bath-one-step dyeing method thereof. Background technique [0002] At present, most of the research on blended fabrics is concentrated on polyester fiber, nylon fiber, cotton fiber, regenerated cellulose fiber (such as Tencel, etc.), through the adjustment of different blending ratios, the advantages of various fibers are fully utilized, and the strengths and weaknesses of various fibers are used. The weaving and wearing properties of the fabric have been greatly improved. [0003] PBT fiber is the abbreviation of polybutylene terephthalate fiber, which is esterified by terephthalic acid (PTA) or dimethyl terephthalate (DMT) and 1,4 butanediol (BDO). Or after transesterification, the polymer is obtained by polycondensation, and then the fiber is obtained by melt spinning, which belongs to a kin...
