Abstract: Glow discharges and low temperature plasmas and their applications have increasingly entered various areas of industrial applications. The textile industry is a developing area for application of atmospheric plasma techniques with significant growth potential. Technological advances made possible by plasma processes can reduce the costs for production by reduction in process times, improve the quality of product, generate products with new surface or bulk properties, and contribute to an environmentally sustainable work environment. A novel dual functional textile material was developed which possesses co-existing hydrophobicity and hydrophilicity on opposite faces utilizing atmospheric pressure plasma. One side of the substrate repels water whereas the other side absorbs water. The sequence and chemistry of the plasma aided side specific treatment of poly (ethylene terephthalate)/ polyurethane blend knitted fabric and cellulose with fluorocompound namely 1, 1, 2, 2- tetrahydroperfluorodecyl acrylate (70- 90%) and 1, 1, 2, 2- tetrahydroperfluorododecyl acrylate (10- 30%) was demonstrated to obtain the dual functionality. Effect of process and device parameters such as variation of (1) flow rate of monomer, (2) flow rate of helium and (3) flow rate of argon, (4) RF power, (5) time of plasma exposure to the fabric, (6) gap between electrodes, (7) prewashing the material before treatments and (8) preliminary plasma treatment on the fabric performance was also studied in this research.
