摘　　要：研究了拉伸前后莱卡皮革的绵羊服装蓝湿革组织结构的变化,探讨了拉伸对皮革组织结构的普遍影响。结果显示:拉伸后纤维束向应力方向进行定向排列;而从皮革组织结构对其延伸性的影响来看,皮革的延伸性主要取决于皮革结构的紧实程度,皮革结构越松,则其延伸性越大,其对应的应力应变曲线的斜率越小。Changes of leather structure before and after extension were studied with sample of garment wet blue specially made for lycra leather. The influence of extension on leather structure was reviewed. It shows that after extension the fasciculis arrange in order along the stress. There is strong relationship between collagen structure and its extension performance, and the looser the collagen structure, the better extension performance, and the lower slope the corresponding curve has.
