Leather dye is a blend of chemicals and dyes used to colour leather.
Spirit or alcohol-based dyes are commonly used in leather dyeing because the alcohol immediately permeates into soaked leather. Lacquer compositions are similar to leather colouring formulations.
A dye or pigment, a protein isolate or nitrocellulose resin, and a solvent are all incorporated.
The sorts of dyestuff utilised by the leather industry fluctuate based on the product spectrum required as well as the trend world’s mandates. Each tannery is known to use between 50 and 100 different types of dyestuffs.
The fat-soluble components of traditional leather dyes are released from their chemical linkages when subjected to elevated heat. These components are now migrating higher into the strata whose function is to give the leather surface a flawless finish. This results in a noticeable shift in colour and sharpness. So as humidity rises, non-permanent colours that are water-soluble and have a low molecular weight are more prone to be washed off. Along with bleeding and discolouration, there are other issues to consider. There’s also the possibility that dye components that migrate will scrape into other substances like plastics or fabrics.
