Abstract

This study shows the thermal and moisture transfer properties of fabrics used in protective clothing for welders. The purpose of this study is to compare the performance of several fabrics used in protective clothing for welders by transfer test. The moisture transfer was affected by density and thickness of the materials. To improve emissions of water vapor, materials of lower density are suited for protective clothing. The air permeability was affected by coating agents. Silica coating has no effect on permeability of sample. On the other hand, aluminum coating has a bad influence on permeability. To improve air permeability, aluminum coated materials are not suited for protective clothing. Thermal characteristics of the materials were affected by density of the materials. Coated samples have high values of $Q_{max}$. $Q_{max}$ is warmth and coolness at instantaneous contact sense. If $Q_{max}$ shows high values, people feel cool skin sensation. The space of water and air makes the sample to have low values of heat transfer. To improve the effect of insulation, felt materials are suited for protective clothing. Felt materials are good heat blocker due to their high air contents.
