Tie-dyeing method for cashmere textile

Abstract

The present invention discloses a tie-dyeing method of cassimere. Said method includes the following steps: designing pattern of said cassimere and binding; adopting quick penetrating agent SP-2 and Peregal according to a certain mixing ratio to prepare solution, temperature is 40-70 deg.C, bath ratio is 1:15-20, making treatment for 15-20 min; adopting reactive dyes for wool as raw material, using sodium sulfate powder, glacial acetic acid, dye leveler Albatex B for wool and penetrating agent Albatex FFA for wool as adjuvant, after the temperature is risen to 98 deg.C from 70 deg.C, heat-insulating for 20-60 min, making sectional dyeing, then rinsing and cleaning; adopting 3-5% of cashmere bulking agent, 0.3-1% of glacial acetic acid and 0.2-1% of high-effective penetrating agent to make relaxing-bulking treatment, temperature is 40-50 deg.C and making treatment for 20-30 min to make cassimere be flabby, then making milling treatment.

Description

technical field [0001] The invention relates to a method for tie-dyeing cashmere fabrics. Background technique [0002] The basic process of the traditional tie-dyeing method includes: 1. Design the pattern and flower shape of the fabric, then position the pattern and flower shape on the fabric, match the appropriate color, then weave the pattern and flower shape of the fabric, and set the dyeing area The weaving methods include conventional tying methods such as graphic tying method, folding knotting method, sewing method, butterfly flower tying method, centipede thread tying method; 2. Domain-specific dyeing. Dyeing, in the process of dyeing by area, the fabrics are dyed separately according to the design requirements. When dyeing the fabrics of each plate, it is necessary to prevent color shifting and prevent the transition area from being clear. library. This tie-dyeing method is mainly used on silk, cotton, linen and other fabrics or clothing. According to the design ...

AI Technical Summary

Problems solved by technology

At present, there is no process for tie-dyeing cashmere fabrics. Due to the thickness of cashmere fabrics, the penetration and diffusion of dyes and other chemical reagents are hindered. When tie-dyeing, dyes penetrate slowly into cashmere fibers and the coloring fastness is poor. , the anti-dyeing and dyeing areas are blurred, and the visual effect is poor, so the expected design effect cannot be achieved
