AB  - The ripstop fabrics are highly appreciated in the military and defence workwear. One of the qualities requirements in
defence clothing is quick evaporation. The effect of the wearer’s walking speed on textile fabric evaporation during
capillary rise was investigated in this study. To achieve this, two steps were taken: modelling the capillary considering
evaporation and estimating the coefficient of evaporation using a program designed for image analysis. The walking
speed was simulated by varying the air velocity from 0 m/s (non-walking) to 1 m/s (walking) and 2 m/s (running). Results
conclusively demonstrated that the evaporation coefficient is directly relational to the water vapour in the surrounding
air layer and is highly dependent on the aeration rate. Furthermore, liquid equilibrium front level and capillary diffusion
were found to be inversely proportional to the walking speed. The walking speeds affected the indirect water amount on
the fabrics and it was more difficult to evaporate liquid from the 100% cotton compared to 65% polyester/35% cotton/
