Abstract

The behaviors such as smoothness, softness and roughness of fabrics, effectively, are related to fabric structure and physical properties of the material’s fiber. The purpose of this research is the study of influence of relative humidity on adhesion force and frictional properties of plain knitted cotton fabrics. Because of these fabrics directly contact to body skin, therefore it is necessary to determine the role of relative humidity on the fabric pleasantness. In order to this purpose, cotton plain knitted fabrics as subjected to different relative humidity (25%, 50%, 75% and 100%) in the same warm environments (T=50°C). Then the frictional parameters were obtained by using of methods friction. The results showed that relative humidity has statistically significant difference on frictional parameters, thus with rising relative humidity values (in 50°C), decrease resistance friction. Also other results determined the highest roughness values and adhesion force belonged to 25% RH, while the least adhesion force of surfaces happened in 100% RH.
