脂肪醛AAT在铬鞣软革及无铬鞣软革中的应用

一种新型国产脂肪醛鞣剂AAT，分别用于猪正面服装革、水牛沙发革的复鞣、与栲胶联合鞣制猪皮服装革。实验表明，其性能在各个方面与进口脂肪醛相当。ATT用于复鞣能赋予皮革柔软、丰满的手感和弹性，所得皮革粒面细致；用于无铬少铬鞣制作软面革时，能提高皮革的稳定性和收缩温度，减少铬盐用量。脂肪醛AAT已经具备了高端皮化产品应有的特性，值得推广。

Application of a Novel Fatty Aldehyde Tanning Agent(AAT) in the Manufacture of Chrome-Tanned and Chrome Free-Tanned Leathers

A novel fatty aldehyde tanning agent AAT, developed in our Lab, has been used in the retanning process of pig garment grain leather and buffalo sofa leather, and to tan pig garment leather combined with tannin. The qualities of obtained leathers are as same as that of the leathers treated with the imported fatty aldehyde tanning agent. The results indicate that AAT can offer softness, fullness, elasticity and fine grain for leathers, and it also can improve the adsorption of oil and fat. As for its application in the manufacture of chrome-free or chrome less-tanned soft leathers, it can provide leathers with higher stability and shrinking temperature, and result in a decrease for chrome requirement. It is hopeful, as a novel tanning agent with high quality, to be used widely.
