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 blended fiber fabrics has made great progress, the handle of polyester-cotton blended fiber fabrics after general dyeing and finishing treatment is often still relatively hard. , the elasticity and extensibility are poor, and the style is monotonous. When people wear clothes made of this fabric, they will feel tight and stretchy. Moreover, the printing and dyeing performance of general polyester-cotton blended fiber fabrics is poor, mainly because Due to the difference in the properties of cotton and polyester fibers in polyester-cotton blended fabrics, the pre-treatment and dyeing and finishing processes are more complicated, especially the dyeing uniformity of cotton-polyester fibers is relatively difficult, and the technical requirements are relatively high. Therefore, the wearability of the polyester-cotton blended fiber fabric after dyeing and finishing is poor, and the aesthetic feeling is insufficient.
As the traditional polyester-cotton blended fiber fabrics can no longer meet the needs of the market, vigorously developing high-quality products is a key issue faced by polyester-cotton blended fiber fabrics and even clothing manufacturers.

Abstract

The invention discloses a dyeing and finishing process for a polyester blended fiber fabric. The process comprises the following steps of 1, pretreatment, wherein the polyester blended fiber fabric is sequentially subjected to scouring, bleaching and enzyme washing; 2, mercerizing and sizing, wherein the fabric is subjected to padding of alkali liquor under the room temperature for pre-sizing; 3, dyeing, wherein the fabric is soaked into dye liquor formed by disperse dyes, dyeing is performed under the temperature of 30-40 DEG C, temperature is increased to 90-110 DEG C at the heating rate being 0.8-1 DEG C/min, washing is performed through warm water, infrared ray pre-heating is performed, and then hot-blast air drying is performed; padding is performed again under the room temperature to reduce the suspended solid dye liquor formed by dyes, a reduction solution is subjected to padding, steam reduction and oxidation are performed, washing is performed through warm water, soaping is performed, and then washing and drying are performed; 4, after-treatment, wherein soft and flame-proof treatment is performed in sequence. According to the dyeing and finishing process for the polyester blended fiber fabric, the touch feeling, elasticity and other properties of the fabric are improved remarkably, dyeing is uniform, the color fastness is high, and the color is full.

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 blended fiber 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 char...
