In fact, it is not difficult to determine the quality of denim fabrics, but now denim fabrics are constantly innovating and new fabrics are constantly emerging. Therefore, we need to constantly come into contact with new things and improve our identification ability. There are three methods to evaluate the quality of denim fabric.

Due to the continuous emergence of new technologies and products, printing and dyeing factories have been able to solve the old problem of balance between hand feel and fastness in high-end textile pigment printing processing, and have been able to smoothly apply it to various fiber components of non-woven fabrics, ribbed fabrics, and knitted fabrics.

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.
