| Abstract: | A method of treating a fabric including cellulose fiber to increase water absorption and hydrophilicity by graft polymerisation. The method includes pre-treating the fabric in a solution of an inhibitor for about one hour, and washing the fabric to remove excess inhibitor solution. The fabric is placed in a grafting solution of a hydrophilic monomer for about three hours, washed in methanol, and decrystallized in a solution of zinc chloride for about one hour. The decrystallised fabric is then treated in a solution of sodium hydroxide at 50°C. for about one hour. |
