Embodiment

[0014] The specific pre-treatment process of the present invention is as follows: cotton grey cloth → atmospheric air plasma pretreatment → ultrasonic biological enzyme desizing → ultrasonic cotton cleaning enzyme combined with hydrogen peroxide bleaching → hot water washing → cold water washing → drying.

[0015] 1. Atmospheric air plasma pretreatment: pre-baking temperature 80±10℃; in the plasma discharge system, ceramic tube and quartz tube composite components are used to generate composite plasma of different intensities, and the discharge time is 2.2 min~2.6min; The discharge power is 25 KW~30KW.

[0016] The cotton fabric pretreated by atmospheric air plasma can omit the de-boiling process in the pre-treatment and directly carry out the water washing process, and then continue the treatment according to the traditional oxygen bleaching process. This new pre-treatment process can not only achieve the effect of traditional pre-treatment processing, but also eliminates the pre-...

Abstract

The invention discloses an ecological pretreatment process of American cotton fabrics. The ecological pretreatment process comprises the following steps: cotton grey cloth, normal-pressure air plasmapretreatment, ultrasonic biological-enzyme desizing, bleaching by combining ultrasonic wave, cotton cleaning enzyme and hydrogen peroxide, washing with hot water, washing with cold water and drying. The ecological pretreatment process disclosed by the invention has the beneficial effects that the normal-pressure plasma technology and the environment-friendly technologies such as ultrasonic wave, biological enzyme and the like are combined and applied to a pretreatment process of cotton fabrics, wherein by plasma treatment, partial size and impurities on the fabrics can be etched and removed, ultrasonic wave plays a role in cavitation and dispersion, the biological enzyme plays the biggest role in desizing in pretreatment, the combined process can realize a better pretreatment effect, is energy saving, consumption reducing, environmentally friendly.

Description

Technical field [0001] The invention belongs to the field of fabric treatment, and specifically relates to an ecological pretreatment process for U.S. cotton fabrics. Background technique [0002] Compared with domestic cotton, U.S. cotton has the advantages of neat fiber length, uniform thickness, and less foreign fibers. Therefore, it has become the first choice for high-end hotel sets and bathroom products. However, U.S. cotton also has the problem of containing more leaf chips and more cotton materials. . Raw cotton grey cloth needs to go through scouring and bleaching pretreatment process to remove natural impurities and pigments to improve its whiteness performance. [0003] At present, traditional alkali refining and hydrogen peroxide bleaching cotton fabric pretreatment processes are usually used. This process is carried out under high temperature and strong alkali conditions. After bleaching, the cotton fibers are damaged greatly, and a large amount of clean water is requ...
