ibers and fabrics have extensive applications in many fields, including apparel, defense, and transportation, etc. However, most textiles present high flammability and often bring fire hazards. For this, researcher have long developed flame-retardant materials and technologies to achieve flameretardant fibers and their products. For different kind of textiles materials, it is needed to develop distinctively efficient flame retardant systems and employ convenient technologies, thereby achieving flame retardancy while minimizing any deteriorations on other performance. This review focused on recent progress in surface flame-retardant technology for textiles. Traditional flameretardant mechanisms and technologies were briefly introduced. Using our group’s work and other studies as examples, different surface treatment approaches for flame-retardant fabrics were highlighted, such as sol-gel deposition, layer-by-layer assembly, and covalent grafting methods. Also, some explorations of advanced methodologies for producing durable flame-retardant textiles under mild conditions were discussed. Besides,advantages/disadvantages, application potential, and challenges were indicated. Finally, a brief prospect was provided on the potential opportunities of flame-retardant technologies for fabrics, with the aim of guiding the advancement of the textile industries.
