Leather Dyes - What is the dyeing mechanism of leather dyes?
Leather dyeis a compound that makes leather clear and hard.Leather dyeThe dyeing design involves physical and chemical processes from the dye bath to the adsorption on the leather surface, diffusion into the leather, and fixation within the leather, which is closely related toLeather dyecategories, types of leather, and the degree of neutrality in the leather. SoLeather dyewhat is the dyeing mechanism?
Leather dyeThe leather dyeing process and mechanism:Leather dyeThe basic dyeing process can be divided into three stages: adsorption, diffusion, and fixation, which is a complex physical and chemical process.
1,Leather dyeThe adsorption is relatively fast, with dye being adsorbed on the surface of the leather from the solution, achieving equilibrium right from the start of dyeing.
2,Leather dyeDiffusion into the inner layer of the leather breaks the surface adsorption equilibrium, and at this point, dye is again adsorbed from the dye bath to establish a new equilibrium, continuously advancing the dyeing process through diffusion and adsorption.
3,Leather dyeFixation occurs on the leather fibers. This process involves both physical and chemical actions.
Leather dyeControl of dyeing process conditions: the dyeingpHvalue, dyeing temperature, liquid ratio for dyeing, application of additives, mechanical action, and dyeing time.Leather dyeThere are acidic dyes, direct dyes, basic dyes, reactive dyes, metal complex dyes, and other dyes, among which metal complex dyes have extremely superior performance. High-qualityLeather dyedyeing is rapid, with full and bright colors, good coverage and dyeing fastness, while being resistant to water, sweat, friction, and light.
With the implementation of increasingly strict ecological and environmental protection policies, people are paying more attention toLeather dyethe green ecology of leather, and related research has emerged.Leather dyeThe future of leather products will continue to accelerate the trend of green ecological development.
