Abstract
Plasma Utilization for Treating Natural Fabrics and their Blends to Improve their Printability br The surface properties of natural substrates are important determinants of their usefulness and many of the chemical treatments in use are aimed at modifying these properties. Low temperature plasma has been used as an effective means of modifying the surface properties of textile fibres. Chemical modification of fabrics was early used as a tool for imparting it new properties and increasing its effective application for different end¬uses. Nowadays, physical technologies can advantageously replace some of these chemical modifications as environmental friendly processes. br Exposure of materials to suitable plasma treatment can cause both chemical and physical changes on the surface layers so as to provide a more reactive surface without interfering with the bulk properties simply because of the shallow depth of penetration. Hence, a thin surface layer can be formed by means of surface bombardment with ions, electrons and other high energy particles which knock polymer material out of the surface. br In the present work, low temperature aIr plasma is used as an alternative technique to wet chemical fabric treatments, as a clean economic technology, to acquire wool and wooVpolyester blended fabrics the desired characteristics with the least pollution and energy. This technique can be widely used also to reduce the amount of water, dyestuffs and auxiliaries necessary during the different wet processes applied on textile fabrics as well as enhancing surface properties of substrates and thus, improving their printability, whiteness, wettability, tensile strength and colour yield.
