Drying Rate and Moisture Evaporation
topic
Drying rate testing wets a fabric specimen to a defined moisture content and measures mass loss at timed intervals under controlled temperature and air flow, calculating the drying half-life and total drying time; the drying rate index compares fabric drying speed to an open water surface evaporation rate under identical conditions.
Role
Quantifies the speed at which wet sportswear, workwear, or outdoor clothing releases moisture to the environment during post-exercise or post-wetting recovery periods, directly linking fabric structure to physiological comfort during cooling phases.
