Abstract:
Synthetic thickeners, prevail in the printing of pigments due to their low solids content. They moreover offer advantages in quick and easy paste preparation, adjustment of viscosity adjustment and consistency of quality and supply. The print quality was assessed in terms of sharpness ranking, washing fastness and rubbing fastness. Experimental observations showed that sodium alginate gum can be successfully used in textile printing of cotton fabrics as indigenous thickener which is found to be eco-friendly. Eco-printed cotton samples with FeSO4 mordant using 0.5 per cent kokilaksha gum concentration exhibited higher depth of colour, evenness of print, sharpness of print and overall appearance compared to other concentrations (0.1 – 0.4%). All the samples printed with 50:50 and 75:25 arecanut:myrobolan (with FeSO4) as mordant exhibited good (3) to very good (3/4) colour fastness properties compared to samples printed without mordant.
