Abstract

Water evaporation from textiles is important for wear comfort, especially for sportswear, casual wear and underwear. Constant Power Drying Rate Tester (CPDRT) offers fast (< 30 minutes) and versatile measurement of drying rate of fabrics. The operating temperature and water supply rate of CPDRT are adjustable to simulate required skin temperature and sweat rate, respectively. Change in weight of the fabric is continuously measured on a heated plate. This allows real-time observation of the entire drying process when fabric is placed on a heated plate supplied with constant power. This provides comprehensive information which is useful for fabric development. A set of 28 fabrics was tested by CPDRT. The temperature of bare sample stage is 37 °C and water delivery rate is set at 10 ml/hr. The key parameter, drying rate (DR_CP), ranges from 0.32 to 1.69 ml/hr. Statistical tests are conducted to verify the validity and repeatability of CPDRT.
