Tanning chemicals

Tanning agent is an active substance with multiple functional groups, and its molecular structure contains at least two or more functional groups. Tanning agents can form intramolecular bonds with two or more interaction points in the collagen structure, while also breaking some of the intramolecular bonds in collagen and generating more new intermolecular crosslinks, resulting in a tanning effect; The tannin in the tanning agent combines with the active groups of skin collagen, generating new cross-links between adjacent peptide chains and molecules of collagen molecules, thereby strengthening the structural stability of collagen, improving the resistance to bending strength of leather, as well as the resistance to chemical agents and microorganisms. It also greatly increases the shrinkage temperature of collagen, enhancing the moisture and heat resistance stability of collagen, which is a tanning effect. According to chemical properties, tanning agents can be divided into inorganic tanning agents and organic tanning agents. Inorganic tanning agents are mainly mineral tanning compounds; Organic tanning agents can be divided into plant tanning agents, aldehyde tanning agents, oil tanning agents, synthetic tanning agents, resin tanning agents, etc.
