Wetness sensation is a crucial factor affecting wear comfort. In this study, a measurement method that is capable of characterizing the subjective wetness sensation of various textile products, such as sportswear, leisurewear, uniforms and health-care products, was developed. A subjective rating scale was adopted for response measurement and 20 different fabrics varying in fiber composition, yarn type and fabric structure were evaluated by 22 subjects. The testing procedure was standardized, ensuring within-subject reliability and between-subject consistency. This method also displays high sensitivity and the result is rational with barely to slightly wet sensation for the absorbing fabrics and very wet feeling for the hydrophobic ones. In addition, an objective measurement method for evaluating the horizontal wicking area of fabrics utilizing the image analysis technique was developed. Using conventional testing instruments, such as the Gravimetric Absorbency Testing System, Moisture Management Tester, international standard testing methods and the proposed horizontal wicking tester, various objective water absorption and transport properties were measured and their correlation with the subjective wetness rating was studied. Horizontal wicking area and water absorption capacity of fabrics were found to have strong correlation with subjective wetness sensation.
