Embodiment 1

[0038] Take 5 dyeing cups (numbered from 1# to 5#), add various components to the 5 dyeing cups in sequence according to the mass ratio listed in Table 2, add 150mL distilled water, and adjust the pH to 5.0, set the weight to 400g, so that the composition of the enzyme treatment liquid contains 0.01-5.0g / L of protein and 0.01-5.0g / L of cellulase. Then add 20g of knitted weft-knitted fabric dyed with sulfur black, and process it in the dyeing machine for 60min.

[0041] After the treatment, take out 2mL of the treatment solution to measure its glucose content. Then add 2g / L Na to the treatment solution 2 CO 3 , Continue to process for 10 minutes, take out the cloth sample, wash it twice with clean water, and test the hairiness removal rate of the fabric after drying. The results are shown in Table 3.

Embodiment 2

[0046] Cellulase 325i and proteins A, B, C, and D are respectively in a weight ratio of 1:1, mixed evenly in advance, and left for 30 days. Take 5 dyeing cups (numbered from 6# to 10#), according to Table 4 Add various components to 5 dyeing cups in turn, add 150mL of distilled water, adjust the pH to 5.0 with acetic acid and sodium acetate solution, and set the weight to 400g, so that the composition contains 0.01-5.0g / L of protein, cellulase 0.01-5.0g / L enzyme treatment solution, add 20g of knitted weft-knitted fabric dyed with sulfur black, and treat it in the dyeing machine for 60min.

Embodiment 3

[0055] Cellulase 325i and proteins A, B, C, and D were mixed at a weight ratio of 1:1, and then divided into five samples (numbered 11# to 15#) and left for 30 days. Add 60kg of jeans dyed with sulfur black to a 500-pound industrial washing machine, add 600kg of water, heat up to 55°C, add various components to the washing machine in sequence according to the mass parts in Table 6, and adjust the pH to 6.5-7. Enzyme treatment solution containing 1.0-2.0 g / L of protein and 1.0-2.0 g / L of cellulase was obtained in the washing machine, and continued to run for 60 minutes. Take 2mL of the treatment solution to measure its glucose content. Drain the residual liquid, wash the clothes twice with clean water, and after centrifugal dehydration, dry them to test the hairiness removal rate of the fabric. The results are shown in Table 7.

Abstract

The invention belongs to the technical field of biological finishing of textiles and particularly relates to a composition, a set and a treating method for treating a sulfur dyestuff dyed textile. The composition comprises protein with 3%-15% of aspartic acid and cellulase. Before the protein and the cellulase are used for treating surface hairs of the textile, the protein and the cellulase are mixed in advance; or when the surface hairs of the textile are treated, an enzyme treatment solution containing the protein and the cellulase is temporarily formed. The use amounts of the protein and the enzyme in the enzyme treatment solution are 0.01-5.0g / L respectively and the enzyme treatment solution is used for treating for 30-90 minutes at the pH of 4.5-7.0 and the temperature of 40-60 DEG C. According to the composition, the enzyme and the specific protein are mixed; compared with the single utilization of the cellulase, the enzyme treatment effect can be greatly improved, and the adverse factors that the enzyme use amount is great, the textile hair removing rate is low, hair bulbs are easily formed and the wearing performance of clothes is influenced and the like in a process of carrying out cellulase treatment on the sulfur dyestuff dyed textile are overcome; and the composition has the characteristics of stable efficiency, environmental friendliness, simplicity in operation, low cost and the like.

Description

technical field [0001] The invention belongs to the technical field of textile biological finishing, and in particular relates to a composition and a treatment method for improving the surface finishing effect of sulfur dyed fabrics. technical background [0002] Sulfur dyes are one of the commonly used dyes for cotton fabric dyeing. It has been 140 years since the discovery of sulfur dyes, among which dark varieties are the most widely used. Cotton fabrics dyed with sulfur dyes have a lot of hairiness on the surface, which is easy to pilling and pilling in the later wearing process, affecting the appearance and quality of clothing. With the improvement of people's requirements for clothing comfort, cellulase treatment is usually used in textile finishing to remove hairiness on the surface of the fabric, thereby reducing the phenomenon of pilling. [0003] The cellulase treatment process is to hydrolyze the β-1,4 glucosidic bonds of the cellulose in the cotton through the ...
