“…The modi cation of the cotton has been studied. Many papers have been carried out by different methods, such as the coating method (Kwon et al 2020, Li et al 2022, Sallehudin 2022), chemical modi cation e.g., N-halamine and ame retardant chemical (Chen et al 2023), a copper phthalocyanine derivative and benzophenone (Hu et al 2023) and grafting techniques with various monomers, e.g., [2-(methacryloxy) ethyl] trimethylammonium chloride and methyacrylamide (Wang et al 2022), 3-chloro-2hydroxypropyltrimethyl ammonium chloride (Zhai et al 2022) and 4-vinylbenzyl chloride (Tsimpouki et al 2023). From previous reports, the purpose of cationized cotton fabrics was salt free dyeing with the reactive dyes.…”

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.

In this study, to improve the flame‐retardant properties of ramie fabrics (RFs), a polyelectrolyte complex (PEC) was prepared in a one‐step process using biobased guar gum (GG), polyethyleneimine (PEI), and ammonium polyphosphate (APP) and deposited on the surface of the RF to construct an intumescent flame‐retardant coating. Fabrics treated with PEC coatings exhibited excellent flame‐retardant properties. Specifically, the cone calorimeter test results revealed that an increase in sample weight of only 13.23 wt% resulted in significant reductions in the peak heat release rate (pHRR), total heat release (THR), and fire growth rate (FGR) of 91.37%, 65.12%, and 95.28%, respectively. Additionally, the limiting oxygen index (LOI) increased from 19.4% to 33.5%, and the fabrics self‐extinguished immediately after the ignition source was removed during the UL‐94 test. Scanning electron microscopy (SEM) of the char residue revealed expansion bubbles on the surface, suggesting that the PEC coating provides flame retardancy through a synergistic effect involving both the gas phase and the condensed phase. This study provides a simple and convenient solution for realizing green and efficient flame‐retardant coatings on RF.

To bolster the fire resistance of flexible polyurethane foam (FPUF), and a series of FPUF/polyethylenimine/phytic acid (FPUF/PEI/PA) composites were prepared by layer‐by‐layer self‐assembly strategy. Furthermore, the thermal stability, flame retardancy, combustion properties, and char layer were comprehensively evaluated via thermogravimetric analysis (TGA), limiting oxygen index (LOI), UL‐94 vertical combustion test, microcalorimetry (MCC), scanning electron microscopy (SEM), Raman spectroscopy, and tensile testing. TG analysis revealed that the PEI/PA coatings markedly diminished the initial decomposition temperature (T‐5wt%) and char residue at 800°C. FPUF‐6 extended the burning duration by 20 s, a 80% improvement compared with unmodified FPUF, with an LOI value increased to 19.2 vol%. SEM and Raman analyses of the char residues indicated that the PEI/PA coating promoted graphitization degree of the char layer. This work offered novel insights for the development of high‐performance FPUF composites.
