Low energy hydrogen ion shower discharge was produced using a gas discharge ion source to alter the wettability and dyeability properties of cotton fabric. Ion showers of 400 and 600 eV were used and samples were immersed in the discharge for 15, 30, 45 and 60 minutes. Wettability was measured via the capillary rise method by calculating the velocity of the rising liquid front. Results were then crosschecked using the Lucas-Washburn equation by calculating the advancing contact angles. Color properties such as reflectance, tinctorial strength (K/S) and CIEL*A*B* values were measured. Treatment led to various physicochemical alterations depending on beam energy and processing times. High energy shower led to fiber abrasion which gave rise to decreased water-sorption property. Low energy shower and longer treatment duration enhanced hydroxyl groups (O-H) promoting surface activation. Both treatment levels strengthened carbon triple bonds (C≡C) resulting in better dyeability.
