Problems solved by technology

[0002] Traditional continuous open-width pretreatment uses high temperature and concentrated alkali cooking, which takes a long time, consumes a lot of alkali, energy, and water, and causes great damage to fabric fibers. At the same time, residual caustic soda causes high pH value of sewage, which increases the difficulty of sewage treatment.
[0003] Biological enzyme is a non-toxic, harmless, efficient and specific biocatalyst with mild treatment conditions. As a new technology that is safe, effective, clean and hygienic, and reduces environmental pollution, it is currently widely used in the field of textile technology. However, its reaction The steps are cumbersome and the process conditions are high

Embodiment 1

[0037] The preparation method of activator:

[0038] (1) Take 0.3kg of dodecylbenzenesulfonic acid, 0.2kg of ammonium sulfate, 0.2kg of sodium gluconate, and 0.1kg of sodium bicarbonate in parts by weight and add them to 6kg of water in turn and dissolve them at 25°C, then place Add 2kg of absolute ethanol to the reaction kettle and stir for 5 minutes at 25°C. After the stirring is completed, let it stand for 30 minutes, start the heating coil of the reaction kettle to raise the temperature to 80±2°C, keep it warm for 20 minutes, and stir at the same time until the absolute ethanol Completely volatilize to obtain the first mixed solution, which is set aside;

[0039] (2) Take 0.5 kg of 400-mesh microsilica powder in parts by weight, add 0.2 kg of lignin fiber, then add 2 kg of water, and stir in a constant temperature water bath at 25 ° C for 1 hour to obtain the second mixed solution;

[0040] (3) Transfer the second mixed solution to a reaction kettle, fill it with nitrogen...

Embodiment 2

[0044] The preparation method of activator: with embodiment 1, similarity is no longer repeated; Difference is:

[0045]Process method: Send 10kg of fabric into the microwave plasma reaction chamber for microwave plasma surface activation treatment.

Abstract

The invention discloses a low-temperature cold pad-batch pretreatment process for cloth surface, which belongs to the technical field of textiles. The low-temperature cold pad-batch pretreatment process for cloth surface of the present invention includes pre-finishing, freeze-drying, padding working fluid, coiling and sealing stacking, short steam washing, and drying processes, which also includes putting the fabric into microwave plasma reaction The microwave plasma surface activation treatment is carried out in a chamber, and then the fabric is freeze-dried. The invention also discloses a preparation method of the activator. The alkali consumption, energy consumption, water consumption and other indicators of this process are significantly lower than those of the traditional high-temperature alkali-oxygen process, and the product quality is good, so it has a good market prospect.
