针织物厚度的精确测量

Accuracy of thickness measurements on knitted fabrics

织物厚度采用织物厚度仪进行测量,由一定质量的压脚对织物表面施加一定压强,通过压脚的升降测量压脚停止时的位置高度。机织物采用这种测量方法能得到实际的数值,而对针织物而言,预加载荷对测试结果有很大的影响。最近的一个研究项目旨在估计这种误差,以判定该位置高度是否适合推断空载状态下的织物的厚度。

The thickness of textiles is measured with a touching system, by lowering a plate of defined weight and size onto the textile surface and detecting the height in which the plate stops. While this measurement usually results in realistic values for woven fabrics, knitted fabrics often show a significant influence of the thickness resulting from the applied weight. A recent research project thus aimed to measure this deviation and determine whether it is suitable to extrapolate the measured height values to the height of the unloaded fabric.
