鹅绒皮加工过程中组织结构变化的研究Ⅲ．鞣制后鹅皮肤及被毛的亚微结构

Studies on the Structure Changes of the Goose Skin in the TanningProcessⅢ.Ultrastructure of the Goose Skin and Hair after Tanning Pro-Cess

取经过浸酸处理（浸酸液：硫酸３ｇ／Ｌ，甲酸１ｇ／Ｌ，羟基乙酸１ｇ／Ｌ，芒硝６０ｇ／Ｌ，食盐３０ｇ／Ｌ）的冬鹅皮，分别用４种不同方法鞣制后，用透射电镜和扫描电镜观察了其亚微结构变化。结果表明，用由戊二醛（３ｇ／Ｌ）、三氧化二铬（０．６ｇ／Ｌ）、食盐（４０ｇ／Ｌ）、芒硝（４０ｇ／Ｌ）组成的鞣制剂鞣制，效果最佳。用其鞣制后，鹅皮肤的胶原纤维交联度增加，交联键增多，织角增大，原纤维增粗，纤维结合较紧密；鹅被毛仅羽小枝变化较明显，其顶端由正常的细尖状变为弯曲状。

The ultrastructure of the goose skin and hair in winter with four differ-ent tanning processes after the acid treatment(acid treatment liquid:sulfuric acid 3 g/L, formic acid 1 g/L, glycolic acid 1 g/L,sodium sulfate decahydrate 60 g/L and salt 30g/L)was studied with scanning electron microscope and transmission electron micro-scope. It was shown that the tanning result of the group tanned with the tanning agentcomposed of glutaraldehyde(3 g/L),chromium sesquioxide(0.6g/L),salt (40 g/L)and sodium sulfate decahydrate(40/L)is the best one in all the groups. The collage-nous fibers in the dermis after tanning were intervolved compactly and the pliability andtoughness property of the skin increased.The barbules of the hair were turned fromthin-tip to curve.
