Abstract

The thermal properties (thermal conductivity, thermal resistance and actual insulating), permeability properties (water and air) and some dimensional properties (thickness, shrinkage, width) and wicking ability of single jersey, 1x1rib, interlock, single pique and two thread fleece knitted fabrics made from 100%cotton and cotton/Elastane yarns (5%Elastane yarn content) are investigated, in this research. The 5%Elastane yarn is used in this study because many knitting factories and users add an Elastane at this ratio to improve the extensibility of fabrics. The sample fabrics well conditioned for 24 hours at 20oC temperature and 66% relative humidity (RH). As revealed in the result, the thermo-physiological comfort properties of knitted fabrics are influenced by the type of fibers from which the yarns are made. It is found that the thermal (resistance, conductivity and insulation), thickness, shrinkage, width, air and water permeability and wicking ability of single jersey, 1x1rib, interlock, single pique and fleece knitted fabrics made from 100%cotton and cotton/Elastane yarns are significantly different from each other. The overall emphasis of this study is effect of the different materials on thermo-physiological properties of widely produced knitted fabrics.
