Embodiment 1

[0012] The preparation technology of the biological enzyme preparation of embodiment 1 aramid fabric desizing and refining

[0013] Glucose oxidase, esterase, manganese peroxidase and alcohol oxidase are mixed according to the enzyme activity ratio of 2:1:1:1 using a high-speed dispersing mixer to make mixed component A, the preferred glucose oxidase The enzyme activity is 200U / mL; the surfactant fatty acid methyl ester ethoxylate and water are mixed according to the volume ratio of 1:5, using a high-speed dispersing mixer to make a mixed component B; Glycerin and sodium benzoate are mixed according to The ratio of the volume ratio of 10:1 is mixed with a high-speed dispersing mixer to make the mixed component C; the mixed component A, the mixed component B and the mixed component C are mixed according to the volume ratio of 50:5:1, Use a high-speed dispersing mixer to mix to make an enzyme preparation for aramid fiber pretreatment.

Embodiment 2

[0014] Example 2 Desizing and scouring of aramid fabrics is performed using a biological enzyme preparation for desizing and scouring of aramid fibers.

[0015] The main process of desizing and scouring aramid fabrics using the biological enzyme preparation for desizing and scouring aramid fabrics includes: soaking cold pad-batch, stacking for 48 to 72 hours, washing, drying and other steps. Among them, the speed of the cold pad batch is 50 meters per second, the pressure of the pressing roller is 1 to 2 kilograms, and the temperature of the trough is 50 to 70 degrees Celsius.

[0016] In the desizing and refining process of aramid fabrics, biological enzyme preparations are added in the impregnation cold pad batch process. When adding, it needs to be pre-mixed in the chemical tank according to the ratio of biological enzyme preparation to water 1:20. Among them, the water is tap water or soft water, the water temperature requires 50 to 70 degrees Celsius, and the water pH re...

Abstract

The invention relates to an enzyme preparation for aramid fiber pretreatment, and a preparation technology thereof. An aramid fiber sized with a starch and PVA composite slurry has good desizing and refining effects, and a good sharing performance with hydrogen peroxide for oxygen bleaching can be realized, so a treated fabric has good capillary effect, high whiteness, high desizing thoroughness and fluffy and soft hand feeling. Alkaline cold pad-batch and alkaline long-turning processes can be replaced, and existing process equipment is slightly changed, so compared with the alkaline process,the technology of the invention has the advantages of low energy consumption, reduction of the COD content in wastewater, convenience for large-scale production, and good economic, social and environmental benefits.

Description

technical field [0001] The present invention relates to the field of molecular biology. Specifically, the present invention relates to an enzyme preparation for pretreatment of aramid fiber and its preparation process. Background technique [0002] Traditional pre-dyeing and printing processing is carried out under high temperature, high alkali and surfactant. The treatment process consumes a lot of energy and alkaline agents, and the removal of alkaline agent surfactants consumes a large amount of water. The discharge of sewage produces many substances harmful to the environment. In the traditional process, desizing and refining are divided into two steps, which repeatedly consume a large amount of water resources and energy, and do not meet the requirements of "green" and energy saving and emission reduction. [0003] At the same time, traditionally, it has always been a difficult problem to use biological enzymes to remove PVA slurry. The main reason is that the biodeg...
