Research and application progress in fire retardant fabric based on polymeric hydrogel

In order to improve the fire resistance of textiles, this paper reviews the application of hydrogels as a new type of fire retardant materials, because of the high absorbability of hydrogels with a three-dimensional network. Moreover, the fire-retardant mechanism of hydrogels such as endothermic cooling, gas dilution and oxygen isolation in the process of fire extinguishing was systematically described. According to relevant literature, the novel treatment technology of composite flame-retardant fabric was discussed. It was summarized that flame retardant composite fabrics based on hydrogel have excellent flame-retardant property. This paper critically reviewed and analyzed the challenges and opportunities of hydrogels as flame retardant materials in the field of textile thermal protection. It is found that improving the binding fastness between hydrogels and fabrics, developing self-healing flame retardant hydrogel materials and multifunctional flame retardant hydrogel fabrics call for further research.
