黄牛软鞋面革浸灰工艺研究

Study on Liming Process of Cattle Soft Upper Leather

对浸灰工艺进行了对比试验研究，以期通过适当的浸灰工艺减少或消除松面、粗皱。通过对浸灰工艺中的液比、浸灰助剂的种类及用量、操作方式等参数进行对比试验，得出了一个较好的浸灰工艺。从根本上解决了黄牛软鞋面革粗皱问题，生产出了粒面平细、柔软、丰满、弹性好且松面率较低的黄牛软鞋面革。

Liming technology was studied. By proper liming process, grain-loosing and rough wrinkles can be decreased. Liming auxiliaries and high float length are the key points of the process.
