Problems solved by technology

[0003] With the advancement of printing and dyeing processing technology and the development of new additives, although the dyeing and finishing of polyester-cotton interwoven fabrics has made great progress, the hand feeling of polyester-cotton interwoven fabrics after general dyeing and finishing treatment is often still relatively hard and elastic. Poor stretchability and monotonous style, people will feel tight and stretchy when wearing clothes made of this fabric, and the printing and dyeing performance of general polyester-cotton interwoven fabrics is poor, mainly because polyester-cotton The difference in properties of cotton and polyester fibers in interwoven fabrics makes the pretreatment and dyeing and finishing process more complicated, especially the dyeing uniformity of cotton and polyester fibers is relatively difficult, and the technical requirements are relatively high. Therefore, after dyeing and finishing The treated polyester-cotton interwoven fabric has poor wearability and lack of aesthetic feeling
As the traditional polyester-cotton interwoven fabrics can no longer meet the needs of the market, vigorously developing high-quality products is a key issue facing polyester-cotton interwoven fabrics and even garment manufacturers.

Abstract

The invention discloses a dyeing and finishing process for polyester interweaved fabric. The dyeing and finishing process comprises the following steps: S1) pre-treating: performing scouring and bleaching and enzyme washing treatment on the polyester interweaved fabric in turn; S2) pre-shaping: performing pre-shaping treatment on the polyester interweaved fabric; S3) dyeing: soaking the polyester interweaved fabric into a dye liquor at a liquor ratio of 1:(10-30), wherein the dye liquor comprises 1-3% of reactive dyes, 2-5% of rare-earth complex micro-encapsulation disperse dyes, 5-15g / L anhydrous sodium sulphate, 1.5-3.5g / L pH buffering agent, 0.1-0.3g / L organic phenol halide and 0.01-0.05g / L organic fluorinated surfactant; and S4) finishing: performing softening and flame-proof treatment on the fabric in turn. The dyeing and finishing process for polyester interweaved fabric, disclosed by the invention, not only can obviously improve the performances, such as, hand feel and elasticity, of the fabric but also can achieve the effects of uniform dyeing, high color fastness and abundant color and luster.

Description

technical field [0001] The invention relates to the technical field of dyeing and finishing, in particular to a dyeing and finishing process of polyester-cotton interwoven fabrics. Background technique [0002] Fiber is divided into chemical fiber and natural fiber. Natural fiber refers to the fiber that exists and grows in nature and has textile value. Chemical fiber is made of natural polymer compound or artificially synthesized polymer compound. Fibers with textile properties produced by silk and post-processing processes. Chemical fibers have the advantages of light resistance, wear resistance, easy washing and drying, no mildew, and no moths. They are widely used in the manufacture of clothing fabrics, filter cloths, and conveyor belts. , hoses, ropes, fishing nets, electrical insulation wires, medical sutures, tire cords and parachutes etc. Polyester cotton is a kind of composite fiber, including chemical fiber polyester and natural fiber cotton, which has the charact...
