织物润湿性能测试新方法

A novel technique for measuring the wettability of fabric

由于织物的多孔性,液滴在织物表面立刻消失,不能用接触角测量仪测量液滴的接触角。采用一种新的测试方法,可以测量液体在织物表面的接触角,且可测量液体在织物孔隙中形成的毛细接触角,以及与织物的润湿性能有关的某些特征参数。

Since the fabric is porous, the liquid drops will go into pores of the fabric as soon as they come into contact with the fabric surface. A general contact angle meter is not suitable for this kind of measuring. This paper introduces a novel measuring technique which can measure not only the surface contact angle formed with the liquid but also the capillary contact angle in the porous. Besides, it can also obtain some other characteristic parameters of the wettability of the fabric.
