鞋面革透水汽性的测试

对不同鞋面革、鞋里材料单层和复合试样的透水汽性进行了测试研究,结果表明;皮革及其它鞋用材料的透水汽性存在两向差异,即水汽从材料的正面透到反面或从反面透到正面,其透水汽的能力不相同。差异的大小取决于这种材料两面的状态和亲水性的差异。复合试样的透水汽性受组成复合试样的单层材料的透水汽性的大小、孔率、亲水性、表面状态和组合方式的影响。

Testing of the Permeability to Water Vapor of Shoe Upper Leathers

In this paper, testing study had been done on permeability to water vapor of different shoe upper leathers, shoe lining single-layer material and compounded samples. The results showed that there was the bi-difference of permeability to water vapor of leather and other shoe material; in other words, the permeability to water vapor value in material's grain-to-fresh test is inconsistent with which in material ' s fresh-to-grain test. The differences were decided by the two-side state and the hydrophilic of material. The permeability to water vapor of the compounded sample was affected by the size, porosity, hydrophilic, surface state and combined mode of single-layer material of this compounded sample.
