Abstract
A novel chemical formulation for concurrent grafting and dyeing using a potassium permanganate/citric acid system to induce polymerisation of acrylonitrile onto loomstate cotton fabric is described. The critical properties of the fabric, such as graft yield, colour strength before and after soaping and percentage loss in colour strength due to soaping were found to depend upon the concentrations of potassium permanganate, citric acid and acrylonitrile, as well as pH of the treatment bath and the duration of the treatment.
