Application characteristics and dyeing process of special leather dyes
Dyes used in the leather dyeing industry are usually textile dyes. Leather-specific dyes often develop alternatives to biphenyl-1-amine, metal complex dyes, and reactive dyes. Special leather dyes need to bond well with leather fibers. They have good light fastness, wash fastness, abrasion resistance, good leveling properties, safety, and non-toxic characteristics. In contrast, foreign specialized leather dyes are diverse and of high quality. For example, Bayer, BASF, and Sanders have dozens of leather-specific dyes. Since 1995, the German government has banned the production and sale of textiles and leather products dyed with azo dyes because azo dyes can produce carcinogenic aromatic amines, which has had a significant impact on China's dye and leather industry.
Commonly used dyes in leather dyeing are direct dyes and acid dyes. Commonly banned dyes in leather dyes include Direct Black BN, Acid Scarlet GR, etc. Therefore, developing special leather dyes has become a top priority. On the other hand, due to the high hygroscopicity of solid dyes, it can lead to inaccurate weighing, causing pollution and harming the environment during use. Liquid dyes are not only convenient to use but also have good leveling properties. Leather dyeing is not sensitive to pH, liquid ratio, and temperature, so liquid dyes are not sensitive. Dyes have become one of the development trends in leather dyes.
