摘　　要：在植物鞣制过程中添加硫酸铝将加强多酚与胶原蛋白之间的交联,并在胶原蛋白中形成基质。因此,将提高热稳定性。该研究旨在弄清楚含羞草和硫酸铝的添加对皮革的收缩温度,化学性质和形态的影响。通过使用含羞草浓度(15%,20%,25%w/w)和硫酸铝浓度(3%,6%,9%w/w)的变化进行了研究。结果表明,处理影响了化学性能和收缩温度。the addition of aluminum sulfate in vegetable tanning process will strengthen the cross-linking between polyphenols and collagen,and form matrix in collagen.Therefore,the thermal stability will be improved.The purpose of this study is to find out the effect of mimosa and aluminum sulfate on the shrinkage temperature,chemical properties and morphology of leather.The changes of Mimosa concentration(15%,20%,25%w/W)and aluminum sulfate concentration(3%,6%,9%w/W)were studied.The results show that the chemical properties and shrinkage temperature are affected by the treatment.
