In this study, cotton fabric was treated with oxygen, nitrogen and argon plasma application. The plasma application was carried out for 10 minutes at low frequency. Firstly, contact angle of plasma treated samples was measured at the end of plasma treatment. The results showed that the plasma treatment causes to increase the hydrophility of samples. Moreover, it was seen that the type of gas affects the hydrophilic properties of samples. After then the samples were left during 1 month with different conditions which were under normal condition and covered with aluminum foil. Finally, the contact angle of plasma treated samples was measured after 1 month in order to determine the durability effect of plasma treatment on properties of cotton fabric. After the contact angle measurements, the results were evaluated with statistical analyses in terms of the type of gas and storage conditions of plasma treated samples. The results demonstrated that the storage conditions and type of gas affect the hydrophilic properties of plasma treated cotton fabric after 1 month. (C) 2015 The Authors. Published by Elsevier Ltd.
