What are the advantages of leather dyes?
What are the advantages of leather dyes? What are their functions? I believe most friends are still unfamiliar with these questions. However, don't worry too much; this article will mainly discuss knowledge related to leather dyes. If you are also interested in this topic, let's read on together, and I hope this will help you make better choices in the future.
Although leather dyes are used in many industries today, most people still feel unfamiliar when they see them. Therefore, before using them, we first need to know that leather dyes are mostly sodium salts of aromatic compounds (some contain carboxyl -COOH), dispersed in aqueous solution to form colored anions. Acidic dye molecules are small, have strong permeability, and easily diffuse into leather, making them one of the dyes used for leather coloring, which is beneficial for the penetration of leather. From a chemical structure perspective, this product mainly includes aromatic methane dyes, quinone imines, anthraquinones, azo, and nitro. They have good lightfastness and, due to their negative charge, are also suitable for dyeing chromium-tanned leather and other metal-tanned leather with a positive surface charge. In the medium, they can dye protein fibers (leather, fur, wool, silk) and polyamide fibers. Since we are going to use them, we need to know that due to the different properties and processing methods of various leathers, when coloring leather, it is necessary to choose one or more dyes based on the dyeing bath conditions and use appropriate methods for coloring.
Leather dyes and immersion dyeing processes. Manufacturers sometimes provide specialized leather dyes as products. Some chromium and cobalt 1:2 metal complex structures are suitable for dry use in leather spraying. Leather dyes are dyes that can directly dye cotton, linen, and viscose fibers without the aid of mordants. Some varieties of this direct dye are in acidic media, directly affecting the leather. They are relatively inexpensive, have a large molecular weight, and penetrate relatively slowly. Moreover, the effect on dyeing leather fibers is not particularly ideal, and they are also products that have been phased out in the market. In the future, when you see them, you will know that they are environmentally friendly dyes specifically for leather. This type of dye is a weakly acidic dye, an acidic composite dye for leather. This series of products has excellent indicators such as bright leather colors, fast penetration, lightfastness, and wash resistance. The products contain aromatic amines and heavy metals, making them very green and environmentally friendly. They are major products both domestically and internationally. Generally speaking, there are many varieties. Therefore, in daily life, if consumers need to choose leather products, they should not only have a certain understanding but also check the product quality when recycling dyes, and choose leather products with better leather dyes.
After the introduction above, we have further understood the advantages of using leather dyes. In the future, when we see them, we will not feel unfamiliar, and we will not encounter problems frequently during use. Well, that's all for today's content, and I believe there will be more exciting knowledge points to come.
