For investigation of the moisture management properties of bi-layer knitted fabrics, a special knitting structure made of the same or different combinations of yarns of cotton, polypropylene, Microdenier polyester and polyester staple fibre on the face and reverse sides fibre was studied. Moisture management properties, which determine the warm-cool feeling, of the fabrics produced were determined and statistical analysis made. The results indicated that the Microdenier polyester (inner) – Microdenier polyester (outer) fabric had a better moisture management property, providing high levels of comfort, and is recommended for summer, active and sportswear. The results were discussed together with one-way ANOVA test results at a 0.05 significance level. The results indicate that the Microdenier polyester yarn inner and outer layer of bi-layer knitted fabric shows a better moisture management property due to its appreciable wetting radius, as well its good absorption rate, wetting time and spreading speed of sweat, thus exhibiting a very higher level of the comfort property.

Senthilkumar Department of Textile Technology, PSG Polytechnic College, Coimbatore/India In this present study, the effect of filament fineness on yarn wicking and the effect of yarn fineness on fabric wicking is studied. In order to fulfill the objective, 150 denier micro-denier PET yarns containing 34, 48, 108, 144 and 288 filaments were selected.

In this study an attempt has been made to study the influence of laundry performance on the various comfort characteristics of Moisture Management Finished (MMF) knitted fabrics. The influence of laundering on comfort characteristics of MMF microdenier polyester knitted fabrics was studied to find out the durability of the MMF and its capability to withstand at least 20 home laundry cycles. In order to study this effect, the MMF knitted fabrics were subjected to different laundering cycles. It was observed that 10 wash and 20 wash fabrics exhibited a superior performance thereby fulfilling an important parameter of permanent wash proofness.
