Elimination of oily dyeing agent is composed of special fatty acid derivatives and surfactants. It has excellent effects such as oil removal, evenly dye, emulsification decentralization, etc. Read More
The cationic dye has a large affinity for acrylic. When dyeing, it spreads slowly due to fast adsorption, which is prone to dyeing uneven phenomenon. Once the dyeing is incomplete, it is difficult to correct it by extending the dyeing time. When dyeing the cation dye, in order to obtain a uniform dy Read More
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 Read More
pHFor active dyeing, when the pH value is 7 ~ 9, the color difference between the product is normal, indicating that the pH range has little effect on the product color difference, and the presence of a small amount of alkali will not change or destroy the active dye molecules.When the pH value is 8 Read More
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 Read More

Acid dyes refer to a dye that contain acid groups in dye molecules that can be combined with amino groups in protein fiber molecules with ion bonds and applicable under acidic, weak acids or neutral conditions.Its structure is mainly nitrogen and 为, and a few are aromatum methane structures. Dyes an Read More
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 Read More
