    Printing cotton fabrics with reactive dyes of high reactivity from an acidic printing paste
    (WILEY, 2007) El Hamaky, Yasser H.; Tawfeek, Somaia; Ibrahim, Dalia F.; Maamoun, Dalia; Gaber, Said
    The behaviour of reactive dyes of high reactivity during the printing process of 100% cotton fabrics from an alkaline and acidic printing paste was studied in detail. The printing pastes were stored for different periods of time and then the fabrics were printed. The samples were subjected to two methods of fixation, the first by steaming and the second by thermofixation. The effects of different factors such as alkali and acid concentration, storage time of the printing pastes and method of fixation on the K/S values of the prints were investigated. The fastness properties of the printed areas were also measured to determine the improvement obtained by acidic printing with high-reactivity reactive dyes on cotton fabrics.
