Visual Perception and Performance Properties of Fabrics Knitted with Elastic Core Cotton Slub Yarns

In this study, dimensional, physical, visual and thermal comfort properties of fabrics knitted with elastic core cotton slub yarns were analyzed. The yarn production methods (core slub yarn and conventional slub yarn) were also compared according to the fabric properties. Additionally, the influence of slub yarn production parameters (slub thickness ratio and slub length) on the previously mentioned properties were investigated. The results indicated that elastic core fabrics produced with slub length 10 mm exhibited lower spirality property than the other fabrics. Due to their higher thermal conductivity, thermal absorptivity and relative water vapor permeability properties, fabrics produced with slub length 10 mm or slub thickness ratio 2.0 can be preferable for hot climate clothes without regard to yarn production techniques.
