汗湿条件下织物动态水传递的测试与分析

为了分析织物动态水传递性能,自行搭建一种具有芯吸导水功能的显性出汗模拟装置,拍照记录不同时刻织物的润湿图像,利用电子天平在线测量系统实时记录织物在吸水或蒸发过程中重量值的动态变化。利用该装置对6种面料分别进行了单层织物平面内水传递性能和2层织物层间水传递性能的动态测试。结果显示:润湿图像面积、水分在织物平面内的扩散速度、织物的吸水速度可以反映织物动态吸水与扩散性能,织物表面的水分蒸发速度可以评价织物的快干性能;织物层间水传递性能可利用模拟皮肤的水分转移率进行评价。

Measurement and Analysis of Dynamic Water Transfer of Fabrics Under Sweating Condition

In order to analyze dynamic water transfer performance of fabric,an explicit sweating simulation device with water transfer function by wicking strips was established.Wetting images of the fabric at different moments were recorded by camera,and dynamic changes in weight of the fabric during the process of water absorption or evaporation were recorded in real-time with the electronic balance online measurement system.The device was used to test the dynamic in-plane water transfer performance of single-layer fabrics and interlayer water transfer performance of 2-layer fabrics of six fabrics.The results show that the dynamic water absorption and diffusion properties of fabric can be reflected via wetted area,diffusion speed of moisture in the plane of fabric and water absorption rate.The fast-drying performance of fabric can be evaluated based on moisture evaporation rate on fabric surface.The interlayer water transfer performance can be evaluated based on the moisture transfer rate of simulated skin.
