Abstract:

The thermal comfort properties of different bi-layer knitted structures made from Polyester yarn as an inner layer and  Modal/Bamboo yarn as an outer layer have been studied. Four bi-layer knitted fabrics were developed and then analyzed objectively and  subjectively for their comfort properties. The air permeability, thermal conductivity, water vapour permeability, wicking ability and  drying rate were found to be higher and moisture absorbency was found to be lower for bi-layer knitted fabric with one-tuck point made  out of Bamboo as an outer layer compared to all other fabrics. The same structure showed good ranking on subjective rating of thermal  environment scale. ANOVA analysis and Friedman One-Way Analysis of Variance were discussed with 95% significant level.
