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

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

There are many factors that affect the dye dyeing process, mainly including: 1. Dye propertiesThe dye structure and molecular size and shape determine the solubility, diffusionability of dyes, and the height of dyes and fibers. Second, the nature and concentration of the aidThere are many categories Read More

1. Unqualified color plasticityThe color fastness includes sun exposure, soap washing fastness, sweat staining fastness, friction fastness, sublimation fastness, ironing fastness, etc. These fastness is The dyeing process and external conditions are closely related. Therefore, whether the color fast Read More

Polyester fiber with decentralized dyes dyed, during the dry heat treatment process, the phenomenon of decreased color targeting and color -light mutation. It is caused by the heat migration of decentralized dyes.The so -called heat migration refers to a phenomenon of migrating from the inside of th Read More

Before the cold rolling pile, the treatment should be in production:① Use a multi -rolling rolling method to ensure that the liquid penetration is evenly consistent. Generally, two grooves are used, and the front grooves are rolled with three rollers, and the rear grooves are used with two rollers.② Read More

1. TemperatureTemperature is an important factor in controlling uniform dye. When acrylic dyeing with cationic dyes, there is very little dye below 75 ° C. When the vitrification temperature (75-85 ° C) of the dyeing temperature reaches the fiber, the upper dye rate of the dye increases rapidly. The Read More
