Thermo-physiological comfort properties of double-face knitted fabrics made from different types of polyester yarns and cotton yarn

Double-face knitted fabrics with hydrophobic inner and hydrophilic outer layers are characterised by their advantageous thermo-physiological comfort property that facilitates the transport of sweat from skin to outer fabric layer where it can be evaporated easily. In this study, for the production of double-face knitted fabrics, cotton yarn as hydrophilic yarn type and five different polyester filament yarns consisting of standard polyester, hollow polyester, micro polyester, textured polyester and textured micro polyester as hydrophobic yarn type were used. In order to determine the thermo-physiological comfort properties of the fabrics, air permeability, water vapour permeability, thermal conductivity, thermal resistance and overall moisture management capacity were measured. The results were comparatively analysed using statistical methods. The experimental results demonstrated that the polyester-type yarns and the combinations of them with the cotton yarn in fabric layers affected the thermo-physiological comfort properties significantly. The fabrics with polyester-type inner face and cotton outer face showed the best moisture transmission properties.

Flame retardant,anti-static and wear comfort properties of modacrylic/Excel®/anti-static PET blend yarns and their knitted fabrics

Abstract

This study examined the flame retardant, anti-static properties, and wear comfort of knitted fabrics made from three types of yarns composed of modacrylic, antistatic PET, cotton, and Excel^® fibers. A limit oxygen index (LOI) above 28 was observed in the two types of modacrylic knitted fabric specimens made from the Excel^®-included and cotton-blended yarns. The Excel^®-included modacrylic knitted fabric showed superior flame retardant properties to the cotton blended and 100% cotton ones. The anti-static properties of the two types of modacrylic knitted fabrics imbedded with 3?wt. % of antistatic PET fibers were observed experimentally and compared with the anti-static property of the 100% cotton fabric by rubbing with wool and cotton fabrics attached to the measuring apparatus; the Excel^®-included modacrylic knitted fabric showed better anti-static properties. Regarding the wear comfort, quick perspiration absorption, and fast drying properties of the Excel^®-included modacryl knitted fabric was superior to those of the cotton blended and 100% cotton ones. The thermal conductivity of the Excel^®-included modacrylic knitted fabric was lower than that of the cotton blended and 100% cotton ones. This was attributed to the lower intrinsic thermal conductivity of the Excel^® than cotton fibers, and the higher porosity and fabric thickness of the Excel^®-included fabric than the cotton blended and 100% cotton fabrics. The water vapor permeability of the Excel^®-included modacrylic fabric was lower than that of the 100% cotton one. In addition, the Excel^®-included modacrylic fabric appeared to have an inferior tactile hand compared to the cotton blended and 100% cotton fabrics because of its less extensibility, lower compressibility, higher bending and shear rigidity.

Effect of blend proportion on thermal behaviour of bamboo knitted fabrics

This study presents the thermal comfort properties of single jersey knitted fabric structures made from cotton, regenerated bamboo and cotton–bamboo blended yarns. Cotton, bamboo fibre and blends of the two fibres (100% cotton, 100% bamboo, 50:50 cotton:bamboo, 67:33 cotton:bamboo, 33:67 cotton:bamboo) were spun into yarns of identical linear density (20?tex). Each of the yarns so produced was converted to single jersey knitted fabrics with loose, medium and tight structures. The thermal conductivity of the fabrics was generally found to decrease with increase in the proportion of bamboo fibre. The relative water vapour permeability and air permeability of the fabrics were observed to increase with increase in bamboo fibre content. Statistical analysis also indicates that the results are significant for air permeability, thermal resistance, thermal conductivity and relative water vapour permeability of the fabrics.
