Abstract

The invention discloses a heavy pure cotton fabric enzyme padding and stacking pretreatment process after corona discharge plasma treatment, and belongs to the technical field of dyeing and finishing pretreatment. The technological process comprises the following steps of: carrying out the corona discharge plasma treatment for the singed heavy pure cotton grey fabric; carrying out complex enzyme liquid padding for 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; and 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, the energy is saved and the emission is reduced, the production cost is reduced; and the process is a clean production process meeting the environmental protection requirement, so that 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-batch of pure cotton heavy fabrics, in particular to a method for pretreatment of pure cotton heavy fabrics treated with corona plasma by enzymatic rolling, 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 particularly important. ...
