A kind of processing method of boiling, rinsing and washing before dyeing of textile elastic cloth

Abstract

The invention relates to a boiling and bleaching water washing treatment method used before textile elastic cloth dyeing. The boiling and bleaching water washing treatment method uses automatic waterwashing equipment, wherein the automatic water washing equipment comprises a water washing tank, a cloth guiding mechanism and an auxiliary mechanism; a specific method for boiling and bleaching the cloth by adopting the automatic water washing equipment comprises the steps of preparing a cloth bleaching liquid, performing cloth placement, and carrying out boiling and bleaching, water washing andcloth taking; the water washing box comprises a box body and a box cover, wherein the box body is of a hollow cuboid structure with an opening in the upper end; cloth placing openings are symmetrically formed in the left side wall and the right side wall of the box body; a sewer opening is formed in the lower end of the box body; and the box cover is placed at the upper end of the box body. In thewater washing process, the liquid in the box body can be continuously stirred, so that secondary pollution to the cloth caused by too high concentration of the cloth bleaching liquid at a certain position is avoided; and meanwhile, the cloth can be continuously extruded, the cloth bleaching liquid adsorbed in the cloth is pressed out, and the residual of the cloth bleaching liquid is reduced.

Description

technical field [0001] The invention relates to the technical field of textile dyeing, in particular to a method for boiling, rinsing, and washing of textile elastic fabrics before dyeing. Background technique [0002] Elastic fabrics are fabrics with a certain stretching elasticity, including spandex fabrics, nylon fabrics, etc. Because of their excellent elasticity, they are also called elastic fibers. They have been widely used in clothing fabrics and have the characteristics of high elasticity. The main application lies in the manufacture of tights, sportswear, bodyguards and shoe soles, etc. According to the needs of the application, its varieties can be divided into warp stretch fabrics, weft stretch fabrics and warp and weft two-way stretch fabrics. [0003] Elastic fabrics need to go through desizing, scouring, bleaching and washing steps before dyeing. The purpose of scouring and bleaching is to remove natural impurities and artificial impurities on the fabric, impr...

Problems solved by technology

[0003] Elastic fabrics need to go through desizing, scouring, bleaching and washing steps before dyeing. The purpose of scouring and bleaching is to remove natural impurities and artificial impurities on the fabric, improve its whiteness and penetration ability, and it will fade when it is boiled and bleached. To prepare the bleaching solution, the fabric needs to be washed with water after the bleaching is completed to remove the residual bleaching solution, but currently there are some difficulties in the process of washing the elastic fabric: a. Due to the elastic fabric has a certain degree of stretchability , so it is prone to wrinkles during the transmission process. If the wrinkles are not smoothed in time, permanent creases will occur, which will affect the quality of the factory; b. The bleaching solution is easy to gather near the fabric, causing secondary pollution to the fabric, resulting in the residue of the bleaching solution and affecting the washing effect
