Firstly yarns were produced by ring spinning machine using cotton, viscose and acrylic fibres in the mantle and water soluble polyvinyl alcohol (PVA) fibre in the core. Single jersey fabrics were knitted and PVA core was removed subsequently by washing process to create hollow yarn. Weight, air permeability and water transmission rate properties of fabrics were measured before and after washing and compared with reference fabrics. Due to the removal of PVA fibres from the yarn core after washing treatment, air permeability and water vapour transmission rate of the all kind of single jersey fabrics which were produced with hollow yarns increased as well as weight of the fabrics decreased which will cause more comfort during any exercise. It was also found that mantle fibre type and PVA ratio have significant effect on the fabric properties. © 2017 The Textile Institute.en10.1080/00405000.2017.1302634info:eu-repo/semantics/closedAccessair permeabilityhollow yarnKnitted fabricPVA fibreswater vapour transmission ratewettingAir permeabilityFibersKnit fabricsSpinning (fibers)Textile fibersWashingWater vaporWettingWoolYarnFabric propertiesKnitted fabricPermeability propertiesPoly (vinyl alcohol) (PVA)Ring-spinning machinesTransmission ratesWashing treatmentWater transmissionProduced WaterAir PermeabilityCottonFabricPermeabilityPolyvinyl AlcoholWashingYarnArticle10811195719652-s2.0-85015189035Q2
