Embodiment 1

[0011] Anti-wrinkle finishing of pure cotton woven fabrics by using bio-polishing waste liquid: filter conventional cellulase bio-polishing waste liquid, and then concentrate to make the concentration of cellulase protein in water reach 2g / L; add conventional dosage 1 , 2,3,4-butane tetracarboxylic acid is fully dissolved, the temperature of the treatment solution is raised to 95°C, and the heat preservation treatment is carried out for 60 minutes; the catalyst sodium hypophosphite is added in a conventional amount and fully stirred to dissolve, and the cotton woven fabric to be treated is immersed in the The fabric is wrinkle-resistant using a conventional baking process.

Embodiment 2

[0016] Anti-wrinkle finishing of pure cotton woven fabrics by using bio-polishing waste liquid: filter conventional cellulase bio-polishing waste liquid, and then concentrate to make the concentration of cellulase protein in water reach 4g / L; Citric acid is fully dissolved, the temperature of the treatment solution is raised to 95°C, and the heat preservation treatment is carried out for 80 minutes; the catalyst sodium hypophosphite is added in a conventional amount and fully stirred to dissolve, the cotton woven fabric to be treated is immersed, and the fabric is wrinkle-resistant by conventional baking deal with.

Abstract

The invention relates to a method for anti-crease finishing of a cotton fabric with biopolishing waste liquid, belonging to the technical field of textile printing and dyeing. The method provided by the invention comprises the following steps: (1) subjecting conventional cellulase biopolishing waste liquid to filtering and concentration to allow the concentration of cellulase protein in water to reach 2 to 4 g/L; (2) adding a conventional amount of a polybasic carboxylic acid finishing agent, fully dissolving the polybasic carboxylic acid finishing agent, heating the obtained treatment fluid to a temperature of 95 DEG C and maintaining the temperature for 60 to 80 min; and (3) adding a conventional amount of a catalyst, then carrying out sufficient stirring to dissolve the catalyst, soaking a to-be-treated cotton fabric into the obtained solution and carrying out anti-crease finishing on the fabric by using a conventional baking process. According to the invention, the polybasic carboxylic acid finishing agent is prepared from the biopolishing waste liquid and used for anti-crease finishing of the cotton fabric, so recycling of the waste liquid is realized, and residual cellulase is used for reinforcing anti-crease finishing effect of polybasic carboxylic acid on the cotton fabric.

Description

technical field [0001] The invention relates to a method for anti-wrinkle finishing of pure cotton fabrics by using biological polishing waste liquid, which belongs to the technical field of textile printing and dyeing. Background technique [0002] Cotton fiber fabric has many excellent properties, but it is easy to wrinkle during wearing and the wrinkles are not easy to eliminate. Unlike wool fabrics and synthetic fiber fabrics, which can maintain a flat appearance during wearing, so it appears to improve fabric elasticity and The anti-wrinkle finishing is mainly aimed at enhancing the ability of cotton fabrics to recover from creases. The early anti-wrinkle finishing agents have the problem of formaldehyde release, and their application is limited. Therefore, the research and development of formaldehyde-free anti-wrinkle finishing agents for cotton fabrics is becoming increasingly active, mainly including bishydroxyethyl sulfone compounds, epoxy compounds, reactive polyu...
