The basic concept of leather dyeing.
The so-called leather dye refers to the use of artificial methods to dye other fibrous materials into bright and durable organic compounds. Dyes used for dyeing protein leather fibers are referred to as leather dyes. Most leather dyes are water-soluble and, under acidic conditions, undergo adsorption reactions with the fibers in the leather. This process of fixing and coloring is known as the dyeing process of leather products. Leather dyes are required to have bright colors, good affinity for leather fibers, and various durability functions, such as resistance to sunlight, washing, dry and wet conditions, friction, light, sweat stains, and migration. All these effects must meet the professional indicators for leather dyeing.
Currently, there are many classifications of leather dyes. The first type is economical leather dyes, which have a molecular structure of monoazo dyes, are very bright in color, but have relatively poor dyeing fastness on leather and are relatively inexpensive. The so-called acidic black and direct black in the leather dye market belong to economical leather dyes.
The second type is direct dyes, which are dyes that can directly dye cotton, linen, and viscose cellulose fibers without the need for mordants. Some varieties of these direct dyes can directly act on leather dyeing in acidic media. Compared to inexpensive dyes, the molecules of direct dyes are relatively large, and their penetration is relatively slow. Moreover, their effectiveness in dyeing leather fibers is not particularly ideal, and they are products that have been eliminated from the leather dye market.
Next, I will introduce a type of high-end, environmentally friendly leather dye used in leather. This type of leather dye is a weakly acidic dye, specifically an acidic complex dye for leather. This series of products features bright leather colors, fast penetration, and excellent indicators for resistance to sunlight, light, and washing. The products contain aromatic amine substances and heavy metals, providing very green and environmentally friendly functions, making them the leading products among domestic and international leather dyes.
In summary, there are many classifications of leather dyes. Therefore, in daily life, if consumers need to choose leather products, they should not only have a certain understanding of leather dyes but also ensure that they select leather products that use high-quality leather dyes when checking product quality.
