Investigation on permeability and moisture management properties of different denim fabrics after repeated laundering

The physiological comfort determined by air permeability and moisture management properties of fabrics is influenced by various constructional parameters of the fabric which give woven fabric a porous structure. Evaporation of sweat during wear has the potential to cool the body besides restricting the additional weight of sweat being absorbed by the fabric. In this study, comfort characteristics of denim fabrics with different weft yarn of cotton, polyester and core spun Lycra have been discussed. Effect of enzyme washing and repeated laundering on air permeability, moisture management and drying rate has also been discussed. It was observed that air permeability and water vapour permeability of unwashed denim fabrics with cotton weft yarn are significantly higher than the fabric with polyester and Lycra cotton weft yarns. The wetting time is higher for cotton and Lycra cotton yarn fabrics. One-way transport index is highest for Lycra cotton weft fabrics and lowest for fabrics with polyester weft. Fabrics with polyester weft yarns show highest spreading rate, spreading radius and drying rate due to better wicking and hydrophobic nature of polyester fibres.     

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.

Moisture transmission behaviour of individual component and multi-layered fabric with sweat and pure water

Moisture transport through multilayer clothing system is one of the most important aspect governing the comfort and performance of multi-layered clothing system. In the present study, properties critical to functioning of outdoor apparels were tested using sweat and pure water for both multi-layered and single layer components i.e., polyester knitted fabric as inner layer (next to skin), polyester fleece/polyester spacer as middle layer and PU coated nylon as outer layer. Water vapour transmission rate of fabrics when tested with sweat solution was significantly lower as compared to water. Fabric with sweat also showed lower drying rate than with water. For sweat solution, absorption rate is higher for both inner and outer surface as compared to pure water for single layer fabrics. However, the wetting time (inversely related to spreading speed) is higher at inner surface and lower at outer surface. In general, the performance of multi-layered ensemble is dominated by the impact of PU coated layer. Multi-layered structure with spacer fabric as middle layer exhibits better water vapour transmission rate, overall moisture management coefficient and drying rate as compared to multi-layered structure with fleece fabric.
