Grafting of cotton fabrics with diallyldimethylammonium chloride

Abstract

Abstract The grafting of cotton fabrics with diallyldimethylammonium chloride was studied. The objective was to improve reactive dyes adsorption and antibacterial properties. The cotton fabric was modified with the diallyldimethylammonium chloride at room temperature using the redox initiator system of potassium persulfate as an initiator and N,N,N/,N/-tetramethylethylenediamine as an accelerator. It was found that the nitrogen content of the cationized cotton fabrics increased with an increase in the diallyldimethylammonium chloride concentration and stayed constant at a concentration of 40% (v/v). The adsorption of the reactive dyes on the cotton fabrics was investigated. The contact time of the reactive dyes adsorption on the modified cotton fabrics reached equilibrium at 30 minutes. The dye adsorption properties of the modified cottons depended on the concentration of the diallyldimethylammonium chloride, dyes concentration, chemical structure, and molecular weight of the reactive dyes. By grafting the fabrics with the diallyldimethylammonium chloride, the cotton fabric's antibacterial function was also enhanced.
