摘要
用氨基化合物 ,乙醛酸和双氰胺树脂等分别处理浸酸裸皮的软化裸皮后进行少铬鞣制。与未处理的比较 ,蓝革收缩温度升高 ,废液中铬含量降低 ,其中以双氰胺树脂最为有效。
The pickled pelt or bated hides were pretreated separately with glyoxylic acid,amino compounds and dicyandiamide resin etc.,then tanned with less chrome.The results showed that the shrinkage temperature of the wet-bule leather is higher and the amount of chrome in exhausted solution is lower than that of non-pretreated leather.Of all others dicyandiamide resin is the most effective.
