THERMAL COMFORT PROPERTIES OF WEFT KNITTED GARMENTS MADE FROM CONVENTIONAL RING AND COMPACT SPUN YARN (Pages : 11 - 20)
M.R. RASHID, F. AHMED AND A.K. AZADThermal comfort is one of the important aspects of knitted garment. Thermal comfort is related to fabrics ability to maintain skin temperature and allow transfer of perspiration produced from the body. In this research work cotton yarns, produced from same cotton blend were spun according to compact and conventional ring spinning principles in three different counts. Three different knitting structures single jersey, rib and interlock were produced from these yarns. Thermal comfort properties of those fabrics were investigated and compared with each other before and after dyeing processes. When the results were studied, it was observed that higher thermal conductivity and air permeability was found in all knitted fabrics made from compact yarn. Compact yarn based knitted fabrics showed higher water vapor permeability compared to knitted fabrics made from conventional ring yarn due to lesser hairiness and smaller diameter of former of yarn which result in reduced fabric thickness with increased inter-yarn spaces (porous nature of fabrics), leading to easy passage of vapor and hence higher water vapor permeability. Interlock and rib fabrics have remarkably high thermal conductivity compared to single jersey fabrics. On the other hand single jersey fabrics have higher water vapor permeability values than rib and interlock fabrics.Download
