Problems solved by technology

[0004] The above invention mixes cationic dyes and polyester fuels without adding dyes twice to improve delivery efficiency. Although this mixed dyeing process can improve dyeing and finishing efficiency to a certain extent, it cannot maintain the fabric feel, elasticity and High degree of softness while maintaining dye pick-up stability and uniformity

Embodiment 1

[0037] Embodiment 1: a kind of dyeing and finishing process of imitation linen, as figure 1 shown, including the following steps:

[0038] Step a, alkali weight reduction treatment: prepare the gray cloth (the cationic dyeable polyester yarn and ordinary polyester yarn are twisted and interwoven), and put it into the normal pressure J-type weight reduction machine. The alkali weight reduction conditions are as follows: the concentration of sodium hydroxide : 2-10g / L;

[0039] Accelerator 1227: 10 x 10 5 mol / L;

[0040] Surfactant R-201: 0.3g / L;

[0041] Anti-coagulant DN: 0.6g / L;

[0042] According to the bath ratio of 1:10, heat up to 100°C at 1°C / L, keep it warm for 30 minutes, fully carry out alkali reduction treatment, wash 2-3 times with water, and dry at 80°C;

[0043] Step b. Dyeing: put the gray cloth obtained in step a into the dyeing vat, add glacial acetic acid to adjust the pH to keep it at about 5-7, add dye and leveling agent 2B, heat up to 80°C at 1°C / min, ...

Embodiment 2

[0047] Embodiment 2: A dyeing and finishing process of imitating linen, the difference from Example 1 is that in step a, the accelerator added is a concentration of 10 × 10 5 mol / L accelerator 1631, the added surfactant is surfactant R-201 with a concentration of 0.3g / L.

Embodiment 3

[0048] Embodiment 3: a dyeing and finishing process of imitating linen, the difference from embodiment 1 is that in step a, the accelerator added is a concentration of 10 × 10 5mol / L accelerator 1631, the added surfactant is the surfactant AES with a concentration of 0.3g / L.

Abstract

The invention discloses a dyeing and finishing process of linen type cloth and relates to the technical field of textiles. The dyeing and finishing process comprises steps as follows: alkali-minimization treatment, dyeing, dewatering, after-finishing, detection as well as packing and storage. According to the dyeing and finishing process of the linen type cloth, the alkali-minimization treatment is performed before dyeing of the cloth, so that hand-feeling, softness and elasticity of the cloth are improved, furthermore, contaminants on the surface of the cloth can be eliminated, subsequent dyedyeing is enabled to be more stable and more uniform, and color points and color spots on the surface of the cloth are prevented during dyeing.

Description

technical field [0001] The invention relates to the technical field of textiles, more specifically, it relates to a dyeing and finishing process of imitation linen. Background technique [0002] Imitation linen is the most common type of fabric such as sofa releases. Most of the linen-like fabrics are woven with polyester fibers. On the outer tube, the linen-like fabrics are very similar to the cotton-linen fabrics, but the feel is quite different. [0003] In the Chinese invention patent whose publication number is CN103243571A, a mixed dyeing process of cationic dyes and polyester dyes is disclosed. The water in the tank is heated up to 50-60°C by steam heating, and at the same time, the fabric in the dyeing vat is fully stirred. This process lasts for 20-30 minutes. After removing the impurities on the cloth, drain the water in the dyeing vat; then add it to the dyeing vat again. Clean water, and adjust the pH value to keep it between 4-5; add cationic dyes and polyeste...
