开发了一种露水传感器阵列方法来测量不同类型机织物中的面内毛细水流动。所使用的样品是由各种纤维材料制成的机织织物，以及组织密度有系统变化的棉和涤纶长丝织物。通过绘制与时间的平方根的距离得到吸水常数KH(cm/√S)，并由KH估算吸水率。根据沃什伯恩定律，织物中的面内毛细水流动被认为是由纤维-纤维接触点上存在的大小约为1μm的气孔控制的。对于相同纤维和纱线的织物，KH值随着纱线密度的增加而减小。水迁移的面内各向异性表明，对于机织物而言，纱线是驱动水迁移的单元。
A Dew sensor array method was developed to measure in-plane capillary water flow in various types of woven fabrics. Specimens used were woven fabrics made of various fiber materials and cotton and polyester filament fabrics whose weave densities were altered systematically. The water absorption constant KH (cm/√s) was obtained by plotting distance traveled against square root of time elapsed, and water absorptivity was estimated from KH. Based on Washburn's law, the in-plane capillary water flow in fabrics was considered to be governed by the pores with sizes about 1μm present at the fiber-fiber contact points between fibers. The KH value decreased with increasing yarn density for the fabrics made of the same fibers and yarns. The in-plane anisotropy of water migration was suggested that the yarn was the unit for driving water migration in the case of woven fabrics.
