  • Removal of printing paste thickener and excess dye after textile printing
    Patent number: 5405414
    Abstract: In textile printing using a printing paste containing a dye and a biological polymer (or modified polymer) as thickener, removal of the thickener and excess dye is made much more efficient by washing the printed textile in the presence of a suitable enzyme. The enzymatic breakdown of thickener decreases process time as well as the amount of energy and water needed to achieve a satisfactory quality of the textile.
