Introduction to Categories of Leather Dyes
Leather dyes are dyes that have a strong affinity for leather and are often used for coloring leather products. Generally, leather products can be dyed directly using acidic media or alkaline dyes, etc. Most commonly, spraying is used for coloring, with neutral dyes being the most frequently used.
For leather products, to achieve a more uniform color penetration, there are many requirements for leather dyes. Generally, the dyes should be slightly soluble in water and easily soluble in organic solvents such as ethylene glycol, ether, ethanol, or dimethylformamide. Spraying dyes on leather products such as pigskin, cowhide, and sheepskin is very effective. It has gained the trust of many manufacturers, and the leather products produced have a very good texture, vibrant colors, and are very popular among consumers, providing them with more choices.
Secondly, leather dyes can be categorized into many categories or series based on their use or coloring type. According to their use, leather dyes can be divided into two series, one isdseries, which is mainly used for dyeing leather through immersion, and the second isSPseries, which is mainly used for spraying on dry leather.
According to different coloring categories, the dyes that can be used for coloring dry leather are as follows:：The first is acidic dyes, which have a complete color spectrum, and the dyed leather has bright colors, allowing the dye to penetrate deeply into the leather, merging into one. The finished product has a purer color and a unified effect. The second is alkaline dyes, which are mostly used for vegetable tanning. The third is direct dyes, which are mostly used for dyeing chrome-tanned leather. The fourth is reactive dyes, generally applied to products containing trichloroisocyanuric acid groups. The fifth is metal complex dyes, which are generally used for high-grade leather and fur specialty dyes, resulting in brighter colors and relatively softer gloss. The last type is alcohol-soluble dyes, which do not contain water-soluble groups in their molecules and are generally used for coloring leather finishing agents.
In summary, based on the different properties of various leathers, the treatment methods will naturally vary. Generally, when coloring leather, it is necessary to choose one or two suitable methods based on the dyeing bath conditions.
