摘　　要：Greasex 5 0 L是诺和诺德公司生产的碱性脂肪酶。已在皮革工业中广泛使用 ,为了更好地应用这种酶制剂 ,我们对 Greasex 5 0 L在猪皮方面的应用条件进行了研究。采用对比的方法 ,用脂肪去除率和皮革的质量作为评价标准 ,研究结果表明 :( 1 )适量的浸灰酶 NUE0 .6 MPX可使 Greasex5 0 L 的脱脂率增大 ,同时可改善皮革的起绒状况和革身柔软性 ;( 2 )一定量的表面活性剂与 Greasex5 0 L 配合使用 ,有利于脂肪的去除 ,用量为平平加的 0 .0 5 %～ 0 .1 % ;( 3)经 Greasex5 0 L 脱脂的裸皮在鞣制后油脂含量也较低 ,有利于后续工序进行 ,从而使成革粒面平细、革身柔软 ,臀部起绒得到改善 ,染色均匀性良好。Alkaline lipase Greasex 50L is one of the leather enzyme products of Novo Nordisk A/S. After extensive control trials on pigskins, evaluating effects by degree of fat removal and qualities of result leather, we got:1 Fat removal rate can be increased by 10% and leather qualities such as napping and softness can be improved by using Greasex 50L together with liming enzyme NUE 0.6 MPX;2 Some surfactant together with Greasex 50L is good to fat removal, and the recommended ratio is 0.05%～0 1%∶1;3 The fat content in the skins is lower after treated with Greasex 50L,which also benefits the successive processes, such as bating, pickling and tanning. As a result, the leather qualities, such as fineness of grain, softness, napping and evenness of dyeing can be improved.
