北方质次土种绵羊皮制作光面毛革生产工艺的研究

STUDY ON TECHNOLOGY OF DOUBLE FACE OF SHEEP SKIN FROM THE NORTH OF CHINA

采取酶助浸水、分步脱脂、酸性酶软化、铬 -铝结合鞣制、KS- 1树脂复鞣剂和改性戊二醛复鞣填充、分次加脂的工艺路线 ,以蒙古路土种绵羊皮为原料生产光面毛革 ,对浸水酶、软化酶、复鞣材料用量及软化、浸酸时间等重要工艺参数进行了优化 ,得出了利用质次土种绵羊皮加工光面毛革的工艺 。

By choicing enzyme soaking,fractional degreasing and fatten,537 enzyme bating,chrome aluminium tannage,retaning by resin tannin and modify glutaraldehyde etc. have processed double face of sheep skin from north of shaanxi in China.And have examined using quality of soaking enzyme and bating enzyme,time of bating and picking and using quality of retanning agent. Have examined sensory qualities and mechanical properties of testing sample. These data have expressed that quality of crust leather have attainea necessary demand of double face dress.
