Abstract:

In order to investigate the relationship between fabric hygroscopicity and the dynamic friction between fabric and skin, 18 kinds of woven fabrics and 9 kinds of knitted fabrics were chosed to carry out the friction experiment with the same female volunteers’ inner forearm skin. The dynamic friction between fabric and skin were tested by fabric-skin friction tester under wet condition. According to the fabric sample under different wet conditions, the samples were completely infiltrated and then hung naturally in order to drying. The moisture content was used to quantitatively represent the wetting degree of the fabric. It was found that the dynamic friction change trends between the same raw material fabrics and skin were similar, and vice versa. The dynamic friction change trends between different kinds of fabric and skin generally increased and then decreased along with the rising of the fabric moisture content from 10% to 60%. It’s a positive correlation between fiber moisture regain and the fabric moisture content at the peak dynamic friction between fabric and skin under wet condition.

Key words: fabric, skin, dynamic friction, hygroscopicity
