Abstract

The invention relates to a dyeing method for a yarn-dyed wool-like fabric. The dyeing method comprises the following steps: (1) adding an industrial liquid alkaline into a fabric to carry out alkaline decrement treatment; (2) adding a chelating agent GD-108, industrial glacial acetic acid and a disperse dye into the fabric subjected to the alkaline decrement treatment in the step (1) so as to dye the fabric; (3) adding industrial liquid alkaline and industrial sodium hydrosulfite for carrying out aftertreatment on the fabric dyed in the step (2); (4) shaping the fabric subjected to aftertreatment in the step (3); (5) adding an antistatic finishing agent and a soft anti-crease finishing agent for carrying out rolling liquid treatment on the fabric shaped in the step (4); and (6) decating the fabric subjected to rolling liquid treatment in the step (5) to obtain the yarn-dyed wool-like fabric. The dyeing method can be used for effectively improving the comprehensive color fastness of the yarn-dyed wool-like fabric, increasing the saturation degree of color and luster of the fabric, keeping the luster deep, enhancing the hand feeling of the fabric and better keeping the wool-like effect of the fabric; the fabric is bright in luster, flexible and fine in hand feeling; and the problem that a cloth surface is monotonous in color and has no luster because of decrement can be avoided.

Description

technical field [0001] The invention relates to a method for dyeing polyester yarn-dyed wool-like fabrics dyed with masterbatch stock solution. Background technique [0002] In recent years, the output of polyester fiber has increased rapidly, and there is a trend of oversupply, but the output of wool is seriously insufficient. Therefore, developing more and better polyester wool-like products has become an important task for the textile industry at home and abroad. [0003] Polyester fabric has the characteristics of strong and durable, good elasticity, not easy to deform, corrosion resistance, insulation, crisp, easy to wash and quick dry, etc., and is loved by people. [0004] Polyester wool-like fabric is made of polyester filament such as polyester stretched yarn, polyester network yarn or polyester yarn with various special-shaped cross-sections, or blended with medium-long polyester staple fiber and medium-long viscose or medium-long acrylic fiber. The woven woolen-s...
