Basic Knowledge and Common Dyestuffs of Textile Dyeing
Textile dyeing is an essential process for textile processing. Mastering the basic knowledge of textile dyeing and understanding the properties and of common dyestuffs and dyeing methods can help us to select and use dyestuff reasonably, develop the dyeing process correctly for dyeing processing and obtain high-quality dyed textiles. Textile Dyeing Basics 1 What is textile dyeing? Textile dyeing is the process of dyeing textiles products into colored objects by using physical or chemical methods to allow dyes to bond with fibers. Dyeing requirements: uniform dyeing with good color fastness. 2 Dyeing principle: color properties of dyes Dyes have chromophore and auxochrome in their molecular structure, which selectively absorb visible light. When the chromophore and the auxochrome are different, the dyes absorb light differently, and therefore, different dyes have different colors. In addition to differences in hue, the colors of dyes also differ in brightness and saturation. Hue i...
