Dunging was a process used in textile manufacturing to finish printed textiles, particularly those printed with aluminium or iron mordants.
[1] It was a process of exposing mordanted products into a solution of cow dung and hot water.
[6] The treatment got its name from the cow dung that was the primary ingredient used in the formulation.
[9] Dunging removes the thickening agents used in printing and also aids in the detachment of mordants that are only lightly adhered.
Additionally, it completes the mordant's fixation on the material and makes it ready and compatible with the dye.
