CN101871162-A discloses a method for desizing cotton gray cloth. First, desizing is performed by atmospheric pressure dielectric barrier discharge plasma treatment, then chemical scouring and refining, and then bleaching. Although this method is atmospheric pressure plasma treatment, it can be realized on-line Production, but only using plasma for treatment will make desizing incomplete, and the process uses chemical refining, which will produce a large amount of waste water and have adverse effects on the environment
CN102321971A discloses a pre-treatment process of flax fabrics treated with normal-pressure plasma and enzymatic rolling, but the weight of the treated flax fabrics should not be too large, otherwise the treatment effect will be unsatisfactory and the removal of impurities will not be clean

Embodiment 1

[0038] Embodiment 1: Atmospheric pressure plasma treatment of pure cotton thick and heavy fabric rolling enzyme stacking pretreatment process

[0039] combined with figure 1 , the atmospheric pressure plasma treatment process is as follows:

[0040] The pure cotton heavy gray cloth 1 to be processed passes between the two discharge electrodes 4 of the plasma device, and then is wound on an automatic winding machine 6 . The automatic winding machine 6 can wind up the processed pure cotton heavy fabric on-line, and adjust the line speed of the pure cotton heavy fabric by adjusting the rotation speed of the winding shaft.

[0041] Adjust the distance between the two discharge electrodes 4 to be 2 centimeters, first feed the mixed gas from the air guide tube 3, the mixed gas is argon and oxygen with a volume ratio of 99 / 1, and adjust the intake speed to be 4 liters / minute; then Turn on the power supply, close the switch of the plasma generator 2, adjust the plasma discharge powe...

Abstract

The invention discloses a heavy pure cotton fabric enzyme padding and stacking pretreatment process after normal pressure plasma treatment, and belongs to the technical field of dyeing and finishing pretreatment. The technological process comprises the following steps of: carrying out the normal pressure plasma treatment on the singed heavy pure cotton grey fabric; carrying out refining enzyme liquid padding on the fabric; then stacking at room temperature; then carrying out oxygen bleaching and low alkali mercerization; and finally sufficiently rinsing to complete the pretreatment process of the heavy pure cotton fabric. According to the method, the process has the characteristics of being good in treatment effect, little in fabrics strength damage, high in quality, soft in hand feeling, high in capillary effect and good in glossiness; the method provides a condition of high color yield for the subsequent dyeing and printing processing; the process operation is simple and high in controllability; the treated waste water, the pH value and the energy consumption of the process are far lower than the treated waste water, the pH value and the energy consumption of the traditional strong base scouring process; and the process is a clean production process meeting the environmental protection requirement, so that the sewage treatment burdens of enterprises are greatly reduced, the process is very high in social benefit and market prospect, and the process conditions are optimized.

Description

technical field [0001] The invention relates to a pretreatment method for cold pad-batching of heavy cotton fabrics, in particular to a method for pretreatment of thick cotton fabrics processed by atmospheric pressure plasma with enzymatic rolling and stacking, and belongs to the technical field of dyeing and finishing. Background technique [0002] Pure cotton heavy dyed fabrics are mostly used as high-grade decorative fabrics, clothing fabrics and tourism product fabrics, etc. It is one of the fashionable fabrics with market competitiveness and is favored by consumers. However, due to its organizational structure, pure cotton heavy fabrics contain high impurities, and the pretreatment processes such as desizing and scouring are difficult. The whiteness and wool effect of the semi-finished products often fail to meet the requirements of the dyeing process, which affects the appearance quality of dyed products. Therefore, the pretreatment of pure cotton heavy fabrics is part...
