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 s

Embodiment 1-5

[0066] Embodiment 1-5: a kind of processing technology of polyester double-layer four-way stretch fabric, comprises the following steps:

[0067] Step 1, refining: the blank with a length of 2000m (the yarn is obtained by wrapping a polyester yarn with a fineness of 70D on the outside of a spandex yarn with a fineness of 40D, and the blank is obtained from the yarn along the warp direction and Weaving in the weft direction) successively passes through the eight-stage liquid (0.4T in use) for refining treatment, and the temperature of the eight-stage liquid is 50°C-65°C-85°C-95°C-95°C-95°C-80°C ℃-70℃; in the eight-stage liquid, except the fourth stage is the refining agent aqueous solution, the rest are all clear water, and the blank with a length of 2000m needs a total of 35-43min to go through the entire refining process;

[0068] Step 2, pre-shrinking: place the refined blank in a pre-shrinking solution for 25-30 minutes, and the temperature of the pre-shrinking solution is ...

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...
