Vinegar green fiber cluster is a new type of fiber combining acrylic and acetate cellulose in a molecular grade.The section of vinegar and green fiber is close to round. After the contrast, it is closer to the section of cashmere fibers, which not only retains the advantages of acrylic fiber and cel

Disperse dyeing is mainly because polyester fiber is dyed high -temperature and high pressure. Although the dye molecules are small, the dyes molecules are all entered inside the fiber during dyeing. It is to use the dye molecules that do not enter the fiber to destroy and improve the role of improv

The traditional wool stain mainly uses acidic dyes, acid media dyes and metal complex dyes.

The emergence of disperse dye -alkaline dyeing:When decentralized dye dyeing conventional polyester, the general dyeing bath is generally controlled (pH value is 5-6). Due to dyeing under acidic conditions, most of the scattered dye color light is the purest and high -dye rate. However, polyester si

The sustaining agent is often added to the dyeing of cations to reduce the upper dye rate and obtain a uniform dyeing effect. The sustained dye dyes of cationic dyes include cationic sustained dyeing agents and anion -ion slowly dyeing agents.Catalogeny -dye is the most commonly used slow -dye dye i

Con la mejora del cromosoma, el color de las flores impresas está aumentando. Aparecen diferentes colores en las telas de impresión.

HardnessIt is generally believed that the hardness below 50 ppm has no impact, and 20ppm is already a good water.The water quality of the tube yarn is not the same, but the copper and iron ion content in the water should be paid attention.Usually active dyeing is better below 50ppm. The key is the m

1. Overview of soap washing agentThe soap washing agent and cleaning agent in the printing and dyeing aid are collectively referred to as detergents.

The nature and geometric shape of fiberUnder the same spinning conditions, when the fiber is long, the fiber has a large combination force, and the fiber is not easy to draw from the yarn during friction, which helps the wear resistance of the fabric; the fineness of the fiber is moderate conducive

According to the perspective of modern dyeing theory, the reason why dyes can be dyed in dyeing fiber have a certain degree of fastness on the fiber fabric, because the dye molecules and fiber molecules exist in various gravity, the principles and principles of dyes and various types of dyes The dye
