Influence of Blend Ratio on Thermal Properties of Bamboo/ Cotton Blended Woven Fabrics

Prakash Chidambaram, Ramakrishnan Govindan






Abstract


Thermal comfort characteristics of plain woven fabrics made out of 30s Nec cotton in warp and 30s Nec 100% bamboo, bamboo/cotton blended yarns in weft have been studied. The fabric characteristics such as air permeability, wicking, thermal resistance, relative water permeability related to comfort characteristics are discussed. The experimental results show that 30s Nec cotton in warp and 30s Nec bamboo in weft plain woven fabric exhibits higher air permeability when compared to other samples, 30s Nec cotton in warp and 30s Nec bamboo in weft plain woven fabric shows very low thermal resistance and higher wicking rate than other samples. Relative water permeability value of 30s Nec cotton in warp and 30s Nec bamboo in weft fabric is higher and that of 30s Nec cotton both in warp and weft fabrics are lower when compared to other samples.

Key Words: Thermal properties; Air-permeability; Water-vapour permeability; Thermal resistance; Wickability
