(475a) Deep Eutectic Solvents As an Eco-Friendly Flame Retardant for Cotton Fabrics

This work focuses on developing an efficient and eco-friendly deep eutectic solvent capable of imparting flame retardancy to cotton fabrics. The solvents were synthesized by utilizing choline chloride, ethylene glycol, glycerol as hydrogen bond acceptors and phytic acid as a hydrogen bond acceptor at numerous molar ratios. Through a comprehensive study, the surface characteristics of the solvents were studied utilizing Conductor-like Screening MOdel for Real Solvents (COSMO-RS) and Fourier transform infrared (FTIR). The physical properties of the solvents, such as density, viscosity, and thermogravimetric behavior were evaluated. Furthermore, the morphology and fire-retardant properties of the coated textiles were assessed through scanning electron microscopy (SEM), energy-dispersive spectroscopy (EDX), and several different flammability tests. The several different coatings demonstrated enhanced resistance to heat, demonstrated by longer ignition time and reduced rates of heat release and smoke produced. Ultimately, an analysis using Virtual models for property Evaluation of chemicals within a Global Architecture (VEGA) was carried out on both the components of DES and conventional flame-retardant chemicals to evaluate their impact on human and environmental toxicity endpoints. These endpoints encompassed mutagenicity, carcinogenicity, acute toxicity, and bioconcentration factor (BCF).
