|Abstract:||The properties of dref-spun acrylic yarns having polyester, nylon and polypropylene multifilament yarns as core and of 100% acrylic yarn without core have been studied. It is observed that the tenacity and work of rupture of core-spun acrylic yarns are higher than that of 100 % acrylic yarn, whereas the breaking elongation of all the yarns is more or less same. Nylon core yarn apparently exhibits slippage between sheath fibres and core during the application of tensile load. Packing coefficient values indicate that the structures of core - spun acrylic yarns are less compact than that of acrylic yarn. Introduction of core filament improves the regularity of friction - spun yarns.|
