Investigation of comfort properties of knitted fabrics made of core-spun vortex yarns

Different yarn spinning methods with different fiber combinations provide an optimization for the consumer requests of durability, functionality, comfort, and price. Vortex yarns and the fabrics produced from these yarns have aroused interest for the last years owing to lower yarn production cost and the satisfying fabric comfort properties. Within this work, core-spun vortex knitted fabrics of three different yarn count (400, 300, and 200 dtex) with six different core yarn type (70 dtex Polyvinyl alcohol, 110/36 dtex/filament polyester yarn, 80/36 dtex/filament polyester yarn, 110/333 dtex/filament micro polyester yarn, 50/96 dtex/filament, 120 dtex staple polyester vortex yarn) and two different sheath sliver types (100% viscose, polyester-viscose blended sliver) were studied. Moisture management transport property (MMT), water vapor permeability, and air permeability properties of those knitted fabrics were evaluated comparatively. Obtained results were statistically evaluated using three-way ANOVA test. It was determined that core yarn type, sheath sliver type, and yarn linear density were generally influential factors on MMT, water vapor permeability, air permeability properties of the core-spun vortex fabrics at significance level of 0.05. Correlation analyses between yarn hairiness and water vapor permeability as well as between yarn hairiness and air permeability were indicated. The conducted work provides an initial phase toward a better understanding of influence of some core-spun vortex yarn parameters on comfort properties of knitted fabrics.
