摘要
为探寻适合疏软类织物电阻测试的电极及其压力,文章设计轻质三电极系统来研究疏软类织物的压缩性能以及压缩形变对电阻测试的影响。结果表明,不同类型的织物有不同的压缩特征。实验所用的表面起绒类织物、双罗纹和纬平针织物的压缩过程存在2个明显的压缩屈服区域,第1屈服区域在50 Pa附近,第2屈服区域在100~200 Pa附近, 而非起绒织物只有1个压缩屈服区域且不太显著。电极压力对织物的比电阻有显著影响,屈服阶段(100~200 Pa左右)轻压能保证电极与织物表面纤维有效接触的同时,又能兼顾织物不会产生较大压缩变形,该电极压力在100~200 Pa范围能获得较为稳定和准确的比电阻。因此,不同压缩特征的织物应在其适合的压力范围进行电阻测试。
In order to find the suitable electrode and related pressure for the electrical resistance test of fluffy fabric,a lightweight three-electrode system was designed to study the compressibility of fluffy fabric and the effect of compression on the resistance test.The experimental results showed that different types of fabrics have different compression characteristics,and there were two significant compression yield regions in the compression process of the raised woven fabric,interlock-knitted fabric and weft plain stitched fabric.The first yield region is near 50 Pa and the second is near 100~200 Pa.While the non-raised fabric has only one insignificant compression yield region.The electrode pressure has a significant effect on the electrical resistance of the fabric.In the yield stage(about 100~200 Pa),the light compression can not only ensure the effective contact between the electrode and the fibers,but also promise the fabric will not produce large compression deformation.The electrode pressure can obtain a relatively stable and accurate specific resistance in the range of 100 to 200 Pa.Therefore,fabrics with different compression characteristics should be tested for resistance in their suitable pressure range.
