More Information
Summary:This is the method of preparing the modified starch-based retanning agent of leather. It oxidates and decomposes the starch, then react with vinyl monomer to polymerize. This retannage is used to leather cure of retanning, after retanning the leather feels soft and comfortable, exquisite surface, color uniformity, augment ply efficiently, no color withdraw. This chrome tanning can be used before retanning, and it can increase the absorption of the augmet, and decrease the quantity of chrome in the waste solution. The modified starch-based retanning agent of leather is a product valuable to environment protection, and has a significant mean of decreasing industrial pollution.
