改良绵羊皮毛革生产工艺的研究

Study on technology of double face of improved sheep skin

采用酶助浸水、 3次脱脂、同浴浸酸软化、油预处理铬鞣、醛 -树脂 -铬 -铝鞣剂结合复鞣填充工艺路线 ,对主要加工材料用量及工艺参数进行了优化 ,得出了利用改良绵羊皮加工毛革的工艺 ,所得坯革感观和物理性能良好。

By enzyme soaking, three time degreasing,enzyme bating and pickling in a float, oil-chrome tannage, glutaraldehyde-resin-chrome-aluminium combined retanning, the quantities of chief materials and parameters in technology are selected. The technology of double face from improved sheep skin is put forward. The resultant leather possesses good hand feeling and mechanical properties.
