Outline of Final Research Achievements

Two atmospheric pressure plasma jet (APPJ) treatments, APPJ-coating with hexamethyldisiloxane (HMDSO) and APPJ-oxidation, were applied to soil guard and soil release finishes of polyester and cotton fabrics. The APPJ-coating increased the water and oil repellency, and the APPJ-oxidation remarkably increased the wettability of the polyester fiber. It was found that the APPJ-coating prevented the deposition of particulate soils and the APPJ-oxidation promoted their removal by aqueous cleaning. Owing to the granular morphology on the fiber surface, the APPJ-coating had an excellent antifouling property from the viewpoint of the soil guard and release balance. Comparing with the wet chemical treatment, the APPJ treatment was found to be effective for the deposition and removal control of textiles.
