影响成鞋透水气和吸水气性因素探索

Exploration of Measuring Water Vapor Permeability and Water Vapor Absorption of Shoes

对自建的一种成鞋透水气和吸水气性测试方法进行进一步研究,探讨了采用该方法时"出汗假脚"的温度、环境温度、环境相对湿度、环境风速对成鞋透水气和吸水气性的影响。结果表明,随着"出汗假脚"温度的提高,成鞋的透水气和吸水气性逐渐提高;随着环境温度的升高,成鞋的透水气性未发生明显变化,吸水气性略有下降;随着环境相对湿度的提高,成鞋的透水气性逐渐降低,吸水气性几乎不变;随着环境风速的提高,成鞋透水气性变化不是很大,吸水气性逐渐增大。

A testing method was established for water vapor permeability and water vapor absorption of a shoe was further studied. Effect of ＂artificial sweaty foot＂ temperature, ambient temperature, ambient relative humidity and ambient wind velocity on water vapor permeability and water vapor absorption of a shoe was investigated in this article. It was found that water vapor permeability and water vapor absorption of a shoe increased gradually with the temperature rise of ＂artificial sweaty foot＂. Water vapor permeability of a shoe did not take obvious change as ambient temperature rise, and the water vapor absorption of a shoe decreased lightly. As the ambient relative humidity rise, the water vapor permeability of a shoe decreased gradually, and the water vapor absorption of a shoe was nearly invariable. The water vapor permeability of a shoe changed a little and the water vapor absorption of a shoe increased gradually with the ambient wind velocity went up.
