Problems solved by technology

[0005] In the existing production process of this high-quality chemical fiber yarn-dyed fabric, the desizing process uses desizing agents and other auxiliary agents to remove oil stains, impurities and sizing on the fiber surface, but due to the high desizing temperature, the cellulose fiber The degree of oxidized cellulose produced under high temperature alkaline conditions is not easy to control, which will result in a lower dyeing percentage of the fabric in the subsequent dyeing process, and poor dyeing uniformity

Abstract

The invention discloses a cold-batching and open-width desizing process for a chemical fiber fabric, and relates to the technical field of textile printing and dyeing pretreatment. According to the technical scheme, the process comprises the following steps: S1, padding of a cold-batching treatment solution placing the chemical fiber fabric in a padding groove for padding, and padding the cold-batching treatment solution with an evenness padder, wherein the padding groove is filled with the cold-batching treatment solution, and the bath ratio of the cold-batching treatment solution and the chemical fiber fabric is 1 to (1.5 to 1.8); S2, cold-batching treatment; S3, water washing; S4, first open-width desizing; S5, second open-width desizing; S6, unwinding and water washing. By adopting thecold-batching and open-width desizing process, the problems of low dyeing percentage and poor dyeing evenness caused by a poor desizing effect of the chemical fiber fabric are solved. A cold-batchingprocess and an open-width process are combined, so that the chemical fiber fabric can be desized completely, and higher dyeing percentage and dyeing evenness are achieved.

Description

technical field [0001] The invention relates to the technical field of pretreatment of textile printing and dyeing, more specifically, it relates to a cold stacking open-width desizing process of chemical fiber fabrics. Background technique [0002] Before the fabric is weaved, the warp yarns are generally subjected to sizing treatment (the warp yarns are dipped in the sizing solution and then dried), so that the fibers in the yarns are adhered to each other, and a thin film is formed on the surface of the yarns, which is convenient for weaving. Cotton fabrics are generally sized with starch or modified starch sizing or polyvinyl alcohol and polyacrylic acid (ester) sizing, and lubricants, softeners, preservatives and other additives are added to the sizing; the sizing will affect the fabric during the dyeing and finishing process. Wettability, and hinder the contact of chemicals to fibers. In order to ensure the color uptake rate of fabrics in the subsequent dyeing and fini...
