Introduction


Moisture flow through textile materials isimportant in diverse range of textile applications including casual wear,sportswear, and protective wear from their comfort point of view, textileprocessing and cleaning, composite manufacturing liquid transfer through preform and in many other areas and thedesirable attributes of functional sportswear and leisurewear are as follows


Fromthe comfort point of view, moisture transmission through textile material bothin liquid and vapour forms are equally important. Liquid moisture flow through textile materials iscontrolled by two processes-wetting and wicking. Wetting is the initialprocess, involved in fluid spreading; it is controlled by the surface energiesof the involved solid and liquid. In case of textile material as soon as waterwets the fibre, the water enters the inter fibre capillary channel and isdragged along by the action of capillary pressure.


Hydrophobicfibers, by contrast, have low surface energy and repel moisture. Specialfinishing processes can be used to increase the difference in surface energybetween the face of a fabric and the back of the fabric to enhance its abilityto wick.
