Problems solved by technology

This method uses modified resin to pad the fabric before dyeing, and performs pre-setting, which can improve the effect of acetate fiber on hand feeling due to high temperature shrinkage, and solve the problem of large difference in dyeing temperature between acetate fiber and polyester fiber, and the fabric The modified resin on the surface is conducive to the adsorption of disperse dyes, and it is easy to dye deep and thick colors

Abstract

The invention discloses a dyeing and finishing processing method of acetate fiber / polyester fiber blended fabric. The dyeing and finishing processing method comprises the following steps of 1) preparing scouring liquid, and pretreating the blended fabric; 2) padding with modified liquid resin, presetting for 30 to 60 seconds at 130 to 140 DEG C; 3) preparing disperse dye dye liquor of which the pH is 3.5 to 6.0, and dyeing the blended fabric for 30min to 120min under the condition of 100 to 140 DEG C; 4) performing reduction cleaning on the dyed blended fabric, washing, and stoving at 80 to 90 DEG C. The fabric dyed by the dyeing and finishing processing method is uniform in dyeing, good in dye permeability, stable in size, less in strength loss and good in fastness.

Description

technical field [0001] The invention relates to a dyeing and finishing method of blended fabrics, in particular to a dyeing and finishing method of acetate fiber / polyester fiber blended fabrics. Background technique [0002] At present, the commonly used raw materials for textile fabrics on the market are mostly cotton, polyester, nylon and regenerated cellulose fibers. Although these fabrics can basically meet people's needs, there are still some shortcomings. For example, polyester fabric has good heat resistance, breaking strength and washability, but its hygroscopicity is poor and static electricity is serious; acetate fabric has certain hygroscopicity, soft hand feeling, soft luster, comfortable to wear, but its chemical resistance Both stability and breaking strength are poor. And the fabric containing acetate fiber and polyester fiber at the same time can have both aesthetics and comfort and practicality, and can better meet the needs of the market. [0003] Acetate...
