基于环芯电极同心环辐射分布的织物导湿性能表征

运用电阻法测试原理,设计同心环辐射分布的电路和仪器参数,研制各测量点为环芯电极式的织物导湿性能测试仪,用于模拟汗液在织物表面的传导过程,并对涤/棉、纯棉和亚麻织物进行实际测量。试验结果表明,该仪器可获得织物面内多方向的如导湿速率、导湿扩散面积等精准结果,并在此基础上提出织物湿传递性能综合评价方法,为织物导湿性能的客观检测与评定提供一种精准、快速、有效的方法。

Characterization of fabric moisture properties based on ring-core electrodes in concentric with radiating line distributions

By using resistance testing theory, the circuit and instrument parameters of concentric rings with radial distribution were designed, and fabric moisture transfer tester with ring-core electrodes in every measuring points was developed, which could simulate sweat transmission process on fabric surface, and actual conduct measurements for polyester/cotton, cotton and linen fabrics were done. The experi-mental results showed that fabric moisture transmitting indexes in multiple directions, such as moisture wicking rate and moisture transmitting area could be obtained, and based on these, the grade classifi-cation of fabric moisture transfer performance was proposed, which could provide an accurate, fast and effective method for detecting fabric moisture transmitting performance.
