This paper reports on a novel instrument for measuring the water transport behaviour of fabric or paper materials in the transplanar direction. The instrument is unique in that it can not only measure the initial water absorption of the fabric in the transplanar direction, but also the rate of evaporation from the fabric surface after fully saturated with water, with the temperatures of water controlled at different levels simulating the end use conditions of the fabric. Compared with existing instruments for the water transport behaviour of fabrics or papers, the new instrument has a unique mechanism to control the water level underneath the fabric sample at a constant level (i.e. the water level is not reduced with the water transport into or through the fabric sample); as a result, the measurements are not affected by the changes of hydrostatic water pressure during testing. Repeated tests on various fabric samples showed that the measurements from the instrument are accurate, sensitive and reproducible. © 2007 IOP Publishing Ltd.
