To dye fabrics with a deep color, Guangdong Tiansheng New Materials has five suggestions, namely: alkali reduction treatment for polyester fabrics, strengthening impurity and stain removal treatment for dyed fabrics, ultrasonic technology treatment, mercerization treatment for cotton fabrics, and the application of low-temperature plasma technology. By applying these five methods well, the fabric can be dyed dark.

The dyes used in the dyeing factory of Guangdong Tiansheng New Materials belong to direct dyes, which have the following characteristics:Dyeing dyes used in dyeing factories are known for their bright colors, complete chromatography, simple application, low cost, strong adaptability, and excellent fastness.

What is the pre-treatment of hemp? So how should we handle linen fabrics?The total biomass content of fibers such as lignin, pectin, wax, and nitrogen-containing substances in flax and ramie is as high as about 30%, while the non cellulose mass fraction of cotton fibers is only about 6%. These fiber symbionts increase the difficulty of pretreatment before dyeing, especially lignin, which has good chemical stability and is difficult to remove.

1. Emphasizing Solid Content and Neglecting Physical and Chemical Analysis. Expert advice: Many additives users attach great importance to solid content and use the combination of content and unit price as the basis for selection. In fact, it is very unwise to do so. Physical and chemical analysis is the basis for checking the quality of additives, and solid content is only one indicator.

1. Desizing: At present, most denim is softened by cellulase rinsing. In the production of denim, no matter how thick or thin it is, the warp yarn will be coated with a kind of corn starch slurry during the weaving process to improve the stiffness of the yarn. During desizing, cellulase can decompose the size on denim and make the size peel off. Although desizing will slightly fade denim, it will improve the softness and drapability of denim. The light denim after desizing can be made into tablecloth or napkin cloth with soft hand and good drape.

Today, we will talk about the process of textile washing water treatment? I hope the following content can be helpful to everyone. The wastewater first passes through the rotary fine grid and enters the sand settling tank. After the sand settling, the wastewater is lifted and filtered out by a circular mesh filter to remove impurities such as fibers, and then flows into the regulating tank. After the addition of a new mobile pump sludge suction machine, the sludge deposited in the regulating tank will be discharged outside the tank
