【摘要】 ;首先用醛品红染色法对皮组织切片中的弹性纤维进行染色,通过显微镜观察了蓝湿革血管中弹性纤维的结构情况,发现血管中含有较大量的弹性纤维成分。考察了在pH 6.5、40℃、酶用量400U/g皮(酪蛋白水解活力)条件下,三种酶对蓝湿革处理后,革内血管结构的变化情况,结果表明,具有较高弹性蛋白水解活力的酶能很好的破坏血管中的弹性纤维结构,明显改善坯革的血管痕;用适当的蛋白酶处理蓝湿革,可以松散蓝湿革粒面,改善血筋等问题,提高成革的柔软度和品质℃更多还原

【Abstract】 Elastic fibers in the skin tissues dyed through staining method with aldehyde-fuchsin after cutting on a freezing microtome.The results indicated that in the wet blue,the blood vessel contains a large number of elastin.Three different enzyme prepared was used to manage vein marks under pH 6.5,40 ℃with the dosage of the enzyme was 400 U/g(casein activity).The results showed that elastin structure in veininess can be degraded after the use of protease,which have high elastic proteolytic activity.Obviously improve the prominent veins of crust leather.Dealing with wet blue by proper protease has some good effect to increase softness,enhance finished leather quality,such as disperse grain and treatment vein marks problem.更多还原
