无公害工业化生产要求制革企业放弃制革工艺中沿用的传统有害物质,采用新方法生产高质量皮革制品。介绍了中俄科研人员用两种不同的方法(涂布法、浸酶法)和两种不同的脱毛酶制剂进行的生皮脱毛试验。试验证明,用酶制剂脱毛效果良好,完全可以替代传统的硫化碱,同时能够改善制革工艺,削弱碱性物质对皮革表面的侵害,减少制革业对水源污染。

The rawhide industrial production without environmental pollution needs to give up the traditional method and apply modern techniques to improve rawhide quality. The results of the unhairing by two methods and two protease preparations are recommeded. The results prove that the unhairing of two protease preparations can replace traditional unhairing by alkaline sulfide material for the purpose to reduce harm on the epidermis and polluted water in the process of production.
