A novel method for measuring in-plane liquid dynamic transport in fabric.

Fabric liquid dynamic transport capacity is a significant factor on the influence of human clothing comfort. In this study, we present a new approach to test in-plane liquid dynamic transport in a straightforward one-step procedure. In this method, a textile sample is irradiated by a radiation source during wetting. Meanwhile, the optical energy of the transmitted ray is transformed to voltage by a detector and is dynamically recorded by a computer. Eventually, the liquid spread speed and maximum absorption rate of the textile material are defined and obtained on the basis of the voltage. Compared with the standard instrument, the Moisture Management Tester, this new method provides more accurate measuring results for liquid spreading speeds and could be applicable for almost all liquid testing except for volatile fluid.
