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 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
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

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
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 Read More
Considering the adjustment of historical data, coatings ink enjoy the highest percentage growth in the main ink for the second year. The coating ink is slowly eroding the share of active ink. From 2020 to 2021, the market share of coatings increased from 3%to 5%. The forecast shows that by the end o Read More

The slow dyeing property of the leveling agent can inhibit the instant dyeing property at the initial stage of dyeing, which is the primary factor in choosing a leveling agent. The test method of retardation is generally as follows: 1. Experimental materials:Sample: Polyester fabric after deoiling a Read More
RefinedThe nylon fabric contains less miscellaneous, and the purpose of refined is to remove fiber in the process of spinning and weaving.The oil and other dirt. So often combine the retreat or cooking drift. Synthetic agents are commonly used in soap or synthetic detergent. For severe dirty, a smal Read More
