Problems solved by technology

[0007] Although the bio-enzyme pretreatment of cotton fabrics has been studied for many years, it is still limited to batch processing, which not only does not meet the characteristics of continuous production of cotton woven fabrics, but also makes it difficult to use the existing processing equipment of cotton printing and dyeing factories. severely restricted in production

Embodiment 1

[0025] Example 1: 40 s ×40 s Cotton Downproof Cloth

[0026] Technological process: after desizing, cotton woven fabrics are padded with enzyme solution, heat-preserved and piled up, washed with hot water (to kill enzymes), washed with cold water, bleached with hydrogen peroxide and washed with water.

[0027] Among them, the biological enzyme treatment solution is composed of: alkaline pectinase 18g / L, pH8.6-10.0, padding biological enzyme treatment solution, the temperature of the padding enzyme treatment solution is from room temperature to 60°C, the excess rate is 100%, steam The steaming temperature is 55°C, and the steaming time is 60 minutes. After treatment, raise the temperature to 95-100°C for 5 minutes to inactivate the enzyme, and wash thoroughly with water. Finally, bleach with hydrogen peroxide and rinse with water after bleaching. The bleaching conditions are: 30% hydrogen peroxide 24g / L, sodium silicate 17g / L, nonionic or anionic wetting and penetrating age...

Embodiment 2

[0029] Example 2: 40 s ×40 s cotton poplin cloth

[0030] Technological process: after desizing, cotton woven fabrics are padded with enzyme solution, heat-preserved and piled up, washed with hot water (to kill enzymes), washed with cold water, bleached with hydrogen peroxide and washed with water.

[0031] Among them, the composition of biological enzyme treatment liquid is: Bacillus subtilis WSHB04-03 produces alkaline pectin lyase 10g / L, wetting and penetrating agent 2g / L, polyoxyethylene type nonionic surfactant and / or anionic surfactant As a wetting and penetrating agent, pH8.6-10.0, padding biological enzyme treatment solution, the temperature of the padding enzyme treatment solution is from room temperature to 60°C, the excess rate is 100%, the steaming temperature is 50°C, and the steaming time is 60min. After treatment, raise the temperature to 95-100°C for 5 minutes to inactivate the enzyme, and wash thoroughly with water. Finally, bleach with hydrogen peroxide an...

Abstract

The invention provided a fore treatment process of the enzyme rolling pile for the fabric which belongs to the fore treatment process of the dyeing and finishing field. The process is: first to impregnate the fabric into the alkali pectinase liquid, then to keep the temperature, next to wash with the hot water (killing the enzyme) and the cool water last to blanch with the H2O2. The pectinase is produced by the Bacillus subtilis WSHB04-03. The process has many merits such as high efficiency, low work output and the energy conservation and so on.

Description

technical field [0001] The invention relates to a pretreatment process of cotton woven fabrics by a biological enzyme pad-batch method, belonging to the technical field of pretreatment processes in the dyeing and finishing industry. Background technique [0002] With the rapid growth of the world population, the textile dyeing and finishing industry continues to develop. The traditional dyeing and finishing process needs to consume a lot of water and chemicals, which not only consumes resources. And produce serious pollution. The fundamental way out to solve this problem lies in the development of environment-friendly dyeing and finishing technology. Biotechnology, especially enzyme processing technology, has shown good development prospects in this regard in recent years. [0003] Biological enzyme is a kind of non-toxic, environment-friendly biocatalyst. The use of biological enzymes in the dyeing and finishing industry has great advantages: (1) As a biological catalyst...
