Abstract
Moisture transmission through textiles has a great influence on the thermo-physiological comfort of the human body which is maintained by perspiring both in vapour and liquid form. The clothing to be worn should allow this perspiration to be transferred to the atmosphere in order to maintaining the thermal balance of the body. Diffusion, absorption-desorption and convection of vapour perspiration along with wetting and wicking of liquid perspiration play a significant role in maintaining thermo-physiological comfort. The scientific understanding of the processes involved in moisture transmission through textiles and the factors affecting these processes are important to designing fabrics and clothing assemblies with efficient moisture transfer in different environment and work load conditions. In this work, we have evaluated the effects of water vapor transmission rate on different fibrous structures: woven fabric with different designs and different layers, knitting fabric with different Lycra percent, hybrid fabric by using sponges between two layers of fabrics and breathable fabric by using PVC nanofibers layer on the weaving fabric. In addition, the results show that fabric structure, breathable fabric and hybrid fabric have a significant effect on water vapor transmission rate (WVTR).
