The purpose of clothing washing is to enhance the stability of clothing. By washing with water, it is possible to shrink in advance and stabilize the size. The second is to enhance the aesthetics of clothing. By using different washing methods, various colors and textures can be washed, which is highly favored by people and increases the added value of clothing. So, what chemicals are used in the washing process of clothing?

The commonly used pre-treatment additives include desizing agents, cleaning agents, scouring agents, penetrating agents, oxygen bleaching stabilizers, chelating agents, etc. Most of these additives are surfactants, organic compounds, inorganic salts, and solvents. The most commonly used surfactants are anionic and non ionic surfactants, and there are also a small amount of amphoteric surfactants.

Woven fabrics, knitted fabrics, and other types of fabrics undergo certain deformations in their original width, length, and other aspects due to the effects of moisture, heat, tension, and other processes such as pre-treatment, dyeing, or printing.

In production, it is common to encounter situations where polyester or polyester containing fabrics are dyed out of the vat, and the fabric surface and color light are normal, but after being processed in the next process, there are color changes or local spots and stripes, as well as a decrease in color fastness. This type of problem can be easily repaired after re repair

The solubility stability of reactive turquoise blue and reactive light yellow in salt and alkali solutions is poor. Once too much or too early salt and soda ash are added, it is easy to produce condensation, which seriously affects the uniform adsorption and diffusion of dyes, resulting in excessive floating color and a decrease in dyeing fastness.

Clothing dyeing not only aims to achieve the desired color and good dyeing fastness for customers, but also requires a good leveling effect. The so-called level dyeing refers to the uniform distribution of dyes in all parts of clothing. This uniform distribution includes the surface of the dye and the uniform distribution of various parts within the fiber.
