Investigating Variation of Dynamic Frictional Effect of Different Textile Fabrics Against Dry and Wet Human Skin Condition at a Fixed Load

Abstract

The principal focus of this experiment was to investigate the dynamic friction properties of different fabric samples at dry and wet skin conditions for a fixed load. The experiment was done by a simple setup with fabric sliding mechanism over human skin for four separate fabric samples of two different categories. Friction forces between different fabrics and human skin were measured through the experimental procedure and afterwards friction coefficient was calculated using Capstan formula from the obtained value of force. It was observed that the friction coefficient of Garment fabrics is lower than that of Special fabrics in dry condition. Wet condition resulted in higher frictional effects than dry condition of the skin providing perfect matching of natural frictional characteristics of any surface. Besides, the wetness of skin, as well as wettability of fabrics, also have a significant influence on the friction coefficient.
