Study Of Mechanical And Physical Properties Of Clothing In Maintenance

The fabrics have a great impact on human comfort. Climatic conditions and physical activity also are important factors. Clothes care by washing is very usual. In this paper, the water vapor permeability and thermal resistance of the clothes during exploitation were tested as the main parameters. The correlation of the physical, mechanical and thermophysiological properties was tested on one non-coated fabric and three different coated fabrics, as well as the changes of water vapor resistance (Ret) during the washing. Standard methods have been applied for testing physical and mechanical properties of fabrics. The hot plate measurements have been used to test the water vapor resistance (Ret) and thermal resistance (Rct). The obtained results indicate that certain properties of yarns for the basic fabric, as well as the characteristics of different polymeric materials (coatings and membranes) used in the production of fabrics and the constructional characteristics of fabrics significantly influence the water vapor resistance and its change during washing. The applied laminating and coating processes have led to the improvement of the physical and mechanical properties of the basic textile material. The influence of water vapor resistance for all tested samples at different temperature, relative humidity and air speed on Ret value of clothes was noticed. These results also determine the application field of tested textile material and the level of protection, i.e. the acceptability class for specified climatic conditions.
