摘要
本文叙述了阴离子淀粉与铝明矾或甲醛结合耗制做白湿皮的研究，结果表明，阴离子淀粉虽然没有显著的鞋制作用，但与铝明矾或甲醛结合获，可以加工成较满意的白湿皮。当阴离子淀粉１％，铝明矾分别为２．５％，５％，１０％时，白湿皮Ｔｓ各达７１．５℃，７４Ｃ，７６．５℃。用阴离子淀粉和甲醛结合效制：液比１．０，常温，ｐＨ８．０，阴离子淀粉１％，甲醛溶液０．５％，时间２～３小时，白湿皮Ｔｓ达８１．５℃，粒面洁白，细致，身骨丰满，采用少铬准制，可节约红矾５０％。制成的成革理化指标，除含铬量稍低外，其他指标均达到部颁指标要求。成革丰满，柔软而有弹性。
This paper focus on the study on anionic starch-aluminium as well as anionic starchformaldehyde combination tannage to manufacture wet-white leather. The consequence shows that satisfactory wet-white leather can be resulted if combination tannage is applied,in spite of the weak tanning action of anionic starch. When 1% anioniC starch is emoployed tab gether with 2. 5%, 5%,and 10% alum respectively,the shrinking temperature(Ts) of wet white leather can reach 71. 5℃, 74℃ and 76. 5℃ respectively. In the combined tanning with anionic starch and formalde hyde,the float is 100%,temperature ordinary and pH value 8. 0,the amount of anionic starch is 1 % diluted for maun 0. 5%,in 2 to 3 hours. The Ts can reach 81. 5℃, whats more,fiou wet -white 1bather with white and fine grain is resulted. And if less chrome tannage is applied,the consumption of bichromate can be reduced by 50%, and on the phySical and chemical properties reach the standardhations of leather products except that the chrome content is a little lower,and the leather is soft and springy.
