This research work was carried out to study the thermal comfort characteristics of three thread fleece fabrics. Polyester filament, spun polyester, polyester/cotton and 100% cotton yarn was used to produce different fifteen samples with different fiber composition having same GSM (280) and thermal characteristics such as thermal conductivity, thermal resistance, relative water vapor permeability and their impact were analyzed. 90% cotton/10% polyester was observed with lowest thermal conductivity and with increasing the polyester percentage thermal conductivity increasing up to 65% cotton/ 35% Polyester. In case of thermal resistance higher resistance was observed for 90% cotton/10% polyester and with the increasing of polyester percentage thermal resistance decreases. The sample containing 90% cotton/10% polyester to 80% cotton/20% polyester showed the lowest and 65% cotton/35% polyester was found highest water vapor permeability. After total analysis of the samples 90% cotton/10% polyester containing three thread fleece fabric are recommended as best winter item.
