Problems solved by technology

However, in the process of dyeing sensitive colors, light and thin fabrics often have problems such as color stains, white spots, floating colors, etc., and even cause the fabric to be scrapped
This is related to factors such as the higher oil content of light and thin fabrics than ordinary fabrics, poor high-temperature dispersion stability of dyes selected for sensitive colors, and polyester oligomers.

Embodiment 1

[0024] A light and thin fabric 16kg: 30D / 36F semi-dull DTY constant force cotton wool composite cloth base material.

[0025] Dye in BRAZZOLI (U-shaped tank, S.p.A 20030, product name: AQUARIUS HT 50 (50Kg)) dyeing machine.

[0026] 1. Pre-treatment process: first open the fabric, then inject industrial soft water into the dyeing vat at a bath ratio of 1:15, put the polyester light and thin fabric into the BRAZZOLI vat, dilute the degreaser KIERALONF- in the attached vat MFB (BASF Chemical Co., Ltd.) 2g / L, injected into the dye vat, heated up to 90°C, kept warm for 30 minutes, then washed with water at 60°C for 10 minutes, and then washed with water at 40°C for 10 minutes to leave the vat. Dehydration, fabric arrangement, and high temperature presetting.

[0027] 2. Dyeing process: Add industrial soft water with a bath ratio of 1:15 into the BRAZZOLI (U-shaped cylinder S.p.A 20030, product name: AQUARIUS HT 50 (50Kg)) cylinder, put the pre-shaped fabric into it, first in the ...

Embodiment 2

[0032] Dye in BRAZZOLI (U-shaped tank, S.p.A 20030, product name: AQUARIUS HT 50 (50Kg)) dyeing machine.

[0033] A light and thin fabric 20kg: 50D / 72F full-dull polyester high-gauge cotton fleece.

[0034] 1. Pretreatment process: Since the cloth is in an open state after weaving, it can be directly put into the vat for production. Inject soft water for industrial use into the BRAZZOLI (U-shaped tank, S.p.A 20030, product name: AQUARIUS HT 50 (50Kg)) dyeing tank at a liquor ratio of 1:15, and put the above-mentioned light and thin polyester fabrics into the BRAZZOLI tank and the attached tank Dilute the degreasing agent KIERALONF-MFB (BASF Chemical Co., Ltd.) 2g / L, and inject it into the dyeing vat, raise the temperature to 90°C, keep it warm for 30 minutes, then wash it with water at 60°C for 10 minutes, and then wash it with water at 40°C for 10 minutes and leave the vat. Dehydration, fabric arrangement, and high temperature presetting.

Abstract

The invention relates to a dyeing method for preventing stains, white spots and floating colors on the surface of light and thin fabrics, comprising: pre-treating light and thin fabrics: opening width, pre-shrinking and pre-setting; dyeing: after degreasing once, Add color repair agent HS‑200, high temperature leveling agent, oligomer dispersant, chelating agent, glacial acetic acid and sodium acetate into the dye vat in different batches, the pH of the dye solution is 3.8-4.3, then add dye and disperse After dyeing, wash, dehydrate, arrange, shape, and roll to obtain light and thin fabrics without stains, white spots, and floating colors on the surface of the fabric. The method of the invention greatly improves the problems of color stains, white spots, floating colors and other defects in light and thin fabrics, and the process is stable and simple.

Description

technical field [0001] The invention belongs to the field of dyeing and finishing of fabrics, and in particular relates to a dyeing method for preventing surface stains, white spots and floating colors of light and thin fabrics. Background technique [0002] Nowadays, the trend of thinning and thinning high-grade outdoor fabrics is becoming more and more obvious. However, in the process of dyeing sensitive colors, light and thin fabrics often have problems such as color stains, white spots, and floating colors, and even cause the fabric to be scrapped in severe cases. This is related to factors such as the higher oil content of light and thin fabrics than ordinary fabrics, the poor high-temperature dispersion stability of dyes selected for sensitive colors, and polyester oligomers. The present invention aims at this kind of dyeing problem, adopts methods such as before and after pre-setting, that is, pre-treatment pre-shrinkage, dyeing double deoiling process, adding a stab...
