Study on physiological comfort of fabrics made up of structurally modified friction-spun yarns: Part II - liquid transmission

Abstract

Dref III friction-spun yarn has been structurally modified using polyester filament fibre as core, viscose staple fibre as secondary core and water soluble poly (vinyl alcohol) as sheath. The yarn is then treated with hot water to wash out PVA in the sheath, leaving the twistless viscose staple fibres on the surface. Effect of sheath fibre proportion, fibre fineness and yarn fineness on physiological comfort related properties affecting the liquid transmission behaviour, such as wickability and water absorbency, has been studied. It is observed that the structural modification of yarn influences the liquid transmission behaviour of fabric. All the three factors studied significantly affect the liquid transmission behaviour of the fabric.
