鞋面革透气性测试的研究

对不同鞋面革、鞋里材料单层和复合试样的透气性及其测试的随机性进行了试验研究。结果表明:涂饰和贴膜会降低皮革的透气性。皮革及其它鞋用材料的透气性存在两向差异。复合试样的透气性主要受单层试样本身的透气能力的影响,排列顺序、组合方式是次要因素。在一定范围内,皮革材料的透气性存在一定的随机性。

Study on the Air Permeability Testing of Shoe Upper Leather

The air permeability and the randomness of air permeability test of different shoe upper leather, shoe lining single -layer material and compounded samples were studied. The results show that finishing and transfer coating will reduce the air permeability of leather. The air permeability of leather and other shoe materials has the bi -differential property. The air permea- bility of compounded samples is mainly affected by the air permeability of single -layer samples. The permutation order and the combined mode are the secondary factors. In a certain range, the air permeability of leather material has a certain randomness.
