Classification of DyesI. Classification by Chemical StructureDyes are classified into: azo dyes, anthraquinone dyes, arylmethane dyes, indigo dyes, sulfur dyes, phthalocyanine dyes, nitro and nitroso dyes, as well as other structural types such as methine and polymetrazine dyes, stilbene dyes, and v Read More

IntroductionLightfastness refers to the ability of a dyed material to retain its original color under sunlight. Generally, sunlight is used as the standard for determining lightfastness. In the laboratory, artificial light sources are typically used for ease of control, with calibration applied when Read More

The Impact of Disperse Dye Thermal Migration on Fabric QualityIn the textile dyeing and printing industry, especially in the processing of polyester and its blended fabrics, the phenomenon of disperse dye thermal migration is a common and troublesome problem. Many dyeing and printing companies have Read More

Dyeing reactive turquoise blue is one of the difficulties faced by dyeing factories (especially reactive turquoise blue KN-G, G133, etc.).

How to Choose the Right Reactive Dyes?Ordinary reactive dyes initially produce vibrant colors, but the chemical bonds they form with fibers break after repeated contact with water and detergents, causing dye molecules to detach.How can this problem be solved?1. Choose dyes with high fixation rates. Read More

Uneven dyeing(1) Shape: Stripes, wavy stripes, square patterns, and other designs with varying shades of color appear on the fabric surface. Severe cases exhibit white patches, while mild defects may not be visible under inspection but can be observed as color differences between pages when folded.( Read More
