Effect of chemical modification of cotton fabrics on dyeing properties

The presented research deals with modifying the chemical structure of the cellulosic cotton fabrics by introducing amino groups as new active centers. The properties of the resulting aminated cotton, dimethylaminoethyl (DMAE)-cotton, are evaluated and discussed by studying the dyeability, light fastness characteristics, and fading kinetics. The goal of this study was achieved. The modification succeeded in saving energy by decreasing both the dyeing time and temperature, and the dyeability and light fastness characteristics were improved. (C) 2002 Wiley Periodicals, Inc.
