Example Embodiment

[0012] Example 1 Preparation process of biological enzyme preparation for desizing and scouring aramid fabric

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

Example Embodiment

[0014] Example 2 Desizing and scouring aramid fabrics was carried out using a biological enzyme preparation for desizing and scouring aramid fabrics.

[0015] The main process of using the biological enzyme preparation of aramid fabric desizing and scouring to carry out aramid fabric desizing and scouring includes several steps such as cold padding, stacking for 48 to 72 hours, washing and drying. Among them, the cold-rolled pile cloth travel speed is 50 meters per second, the pressure roller pressure is 1 to 2 kg, and the trough temperature is 50 to 70 degrees Celsius.

[0016] During the desizing and scouring process of aramid fabrics, biological enzyme preparations are added in the cold padding process of the dipping material. When adding, it needs to be pre-mixed in the chemical feed tank according to the ratio of biological enzyme preparation and water 1:20. Among them, the water is tap water or soft water, the temperature of the water is 50 to 70 degrees Celsius, and the pH ...

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...
