Temperature Changes of Fabrics for the Drop Test with Different Volumes of Water
Abstract:
In this paper, the drop test on cotton and polyester fabrics were conducted when 0.5ml and 2ml water dropped on fabric at an ambient temperature of 20 ± 1 °C, relative humidity levels of 65 ± 2%, and an air velocity of 0 to 0.2m/s. The temperature changes on these fabrics were measured. The results showed that it cost much time of 2ml water than 0.5ml water dropped on two kinds of fabrics. As cotton fabric, when 0.5ml water dropped on fabric, the temperature at point 1 changes little than polyester fabric, this isbecause cotton absorbed much water than polyester, there is little water transport to the distance of 6cm. Either 0.5ml or 2ml water dropped on fabric, the time for polyester fabric is shorter than that of cotton fabric, this can be seen the property of drying-fast of polyester fabric.
