Grafting of cotton fabrics with diallyldimethylammonium chloride

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 modi ed 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 modi ed cotton fabrics reached equilibrium at 30 minutes. The dye adsorption properties of the modi ed 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.

Using low concentration polyethylene glycol to regulate the microstructure of ink to improve the printing quality of cotton fabric

“…Among the varied bers available in nature, cotton has the advantage of warmth, non-irritating properties, moisture absorption, breathability, and economic value, making it a popular choice for clothing and home textile products (Guo et al, 2023;Kusuktham, 2024;Soleimani-Gorgani et al, 2023). However, traditional dyeing methods for cotton fabric, such as dipping and padding, have signi cant environmental impacts due to their high energy and water consumption as well as their use of high concentration of inorganic salt (30-100 g/L − 1 ), such as sodium sulfate(Shan Zhang et al, 2023b;López-Rodríguez et al, 2023;Xia et al, 2018).…”
