Diversity in the customer demands and technological developments gave rise to textile industry to tend towards to the new products. Therefore, in order to create different fabric structures, manufacturers started to produce fancy yarns having different structural and appearance features. At present, fancy yarns can be produced by using various techniques and based on the production methods, the thermal properties of the fabrics produced by using these yarns change.
In this study, thermal comfort properties of the knitted fabrics produced by using ribbon fancy yarns manufactured in different raw materials (100% PAC, 50%-50% PAC/wool) and different production conditions (2,4,6 needle; 7,9,11 delivery cylinder rate) are investigated and a comparative analysis of thermal properties is carried out. With the increasing number of knitting needle, yarn structure gets thicker and therefore thermal conductivity of the fabrics produced with these yarns increase. Whereas these fabrics have cooler feeling with the first touch, the fabrics produced with the yarns manufactured under the condition of higher speed of delivery cylinder give warmer feeling.
