Problems solved by technology

However, the gross effect of the fabric obtained by this method is still low, which is not conducive to the subsequent process; and the method needs to be carried out under high temperature conditions and needs a large amount of hot water to wash after the reaction, resulting in waste of energy and water purification resources; the waste water obtained The pH value is high, the COD value is also high, and the foam is serious, which brings great pressure to the wastewater treatment of printing and dyeing

Abstract

The invention provides a preprocessing method of fabric printing and dyeing. The preprocessing method comprises the following steps: a) performing plasma processing on the fabrics to be processed; b) desizing the fabrics obtained in the step a); c) bleaching the fabrics obtained in the step b), and finishing preprocessing of the fabrics. The method provided by the invention comprises the following steps: performing plasma processing on the fabrics to be processed, and then desizing and bleaching the obtained fabrics in turn to finish the preprocessing of the fabrics. According to the preprocessing method, in the process of performing plasma processing for the fabrics, the macromolecular chains of the surface layers of the fibers are broken after the fabrics are subjected to plasma processing and the fibers are in the rough state with uneven appearances, so that the conditions are created for further modifying the materials; or the ions and free groups are generated on the surfaces of the fabrics so as to improve hydrophily and permeability on the surfaces of the fibers, so that the capillary effect of the fabrics is improved. The preprocessing method of fabric printing and dyeing provided by the invention has better effects on saving energy and reducing emission as well.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a pretreatment method for fabric printing and dyeing. Background technique [0002] The capillary effect value of the fabric is an important index to measure the refining effect of the fabric. It directly affects the quality of subsequent processing, such as level dyeing, dyeing rate, fastness and so on. The higher the wool effect of the fabric, the better its wettability, indicating that the better the effect of scouring and impurities removal. The traditional production process of textiles is roughly divided into six steps: sizing, weaving, desizing, scouring, bleaching, and dyeing. The fabric pretreatment process is a basic process in the dyeing and finishing production process. It plays an important role in stabilizing and improving the product quality of the subsequent process and meeting various requirements of customers. Among them, desizing, scouring, bleaching, dyein...
