一种缩短制革浸水时间的方法
摘要：
本发明涉及一种缩短制革浸水时间的方法，在使用Na+与Ca2+进行皮革浸水时，添加蛋白酶与脂肪酶作为助剂，对浸水工序中Na+与Ca2+的浓度进行调节，所述的蛋白酶为解淀粉芽孢杆菌CGMCC No.11218和嗜碱芽孢杆菌高产菌株CGMCC No.6537所产蛋白酶。将传统浸水工序的处理时间缩短，并降低了后续脱毛过程中的硫化钠使用量。
摘要（英）：

The invention relates to a method for shortening leather making soaking time. When Na+ and Ca2+ are used for leather soaking, protease and lipase are added to be used as an auxiliary, the concentration of Na+ and the concentration of Ca2+ in the soaking procedure are adjusted, and the protease is produced by bacillus amyloliquefaciens CGMCC No.11218 and bacillus alcalophilus high-producing strains CGMCC No.6537. The treatment time of a traditional soaking procedure is shortened, and the usage amount of sodium sulphide in the subsequent depilation process is lowered.
