Composition coating dye, leather properties and its ir-spectroscopic identification with collagen

Аннотация

In this work, the physicochemical identification of covering dyes with leather collagen is studied. IR infrared spectroscopic characteristics, coating dyes to some extent enter into chemical interaction with collagen, which gives rise to the further use of these products for top dyeing of leathers. The proposed technology for finishing the front surface of the skin provides an improvement in the adhesion properties of the skin, also leads to the resistance of the coating to multiple bending, resistance to wet friction, and an increase in tensile tension.
