Treatment process of polyester double-layer side-stretch fabric

Abstract

The invention discloses a treatment process of a polyester double-layer side-stretch fabric, and relates to the technical field of fabric processing. Based on the length of 2000m of gray cloth, the treatment process comprises the following steps: S1, refining; S2, preshrinking, namely, placing the refined gray cloth in a preshrinking solution for preshrinking treatment for 25-30 min, wherein the temperature of the preshrinking solution is 80-83 DEG C; S3, pre-shaping; S4, line hanging; S5, decrement, namely, carrying out decrement treatment on the pre-shaped gray cloth in an alkaline-water mixture; S6, dyeing and washing; and S7, dewatering, scutching, softening and shaping, thus obtaining the polyester double-layer side-stretch fabric. The obtained polyester double-layer side-stretch fabric has the advantages of being soft in hand feeling and moderate in gram weight, meanwhile, the obtained polyester double-layer side-stretch fabric has the physical indexes such as good soaping fastness, more importantly, the energy consumption is favorably reduced, and the treatment cost of the polyester double-layer side-stretch fabric is favorably reduced.

Description

technical field [0001] The invention relates to the technical field of fabric processing, more specifically, it relates to a process for treating a polyester double-layer four-way stretch fabric. Background technique [0002] Polyester double-layer four-way stretch fabrics are usually thicker than all-polyester four-way stretch fabrics, and the double-sided texture is better than all-polyester four-way stretch fabrics. [0003] The treatment process of the traditional all-polyester four-way stretch fabric includes refining-pre-drying-shrinking-dehydration-opening-presetting-reduction-dyeing-dehydration-opening-setting, and the specific operations are as follows: [0004] S1, Refining: Pass the billet successively through containers with a water capacity of 2T-2T-5T (adding 3kg refining degreaser ZFW)-5T-2T, and the temperature of the water in them is 50°C-75°C-95°C ℃-75℃-20℃, it takes 30 minutes for all blanks to be refined; [0005] S2, pre-baking: at a temperature of 120...

AI Technical Summary

Problems solved by technology

In the refining process, the number of stages passed is small, and although each stage has a relatively large water content, the temperature in each stage changes greatly. For all-polyester four-way stretch fabrics, it can better remove the fabric However, for the relatively thick polyester double-layer four-way stretch fabric, it is difficult for the remaining slurry and impurities in the fabric to be fully removed by 5 stages of water with large temperature changes.

And after the refining process, the operation of pre-drying and then pre-shrinking is adopted. The temperature used for pre-drying is as high as 120°C. Although to a certain extent, this step can make the polyester double-layer four-way stretch fabric have better luster degree and feel, but the cost of this step is relatively high, which is unfavorable to production enterprises
