Cellulose-based natural textile materials are highly flammable, which limits their use in areas with high fire safety requirements. Improving their fire resistance while maintaining their mechanical properties is an urgent scientific and practical problem. In this study, a TEX-1 oligomeric flame retardant was developed, synthesized on the basis of aluminum hydroxide as nitrogen, phosphorus and metal additives. The physicochemical properties of the synthesized oligomeric flame retardant were studied. Natural textile materials were treated with TEX-1 flame retardant and their fire resistance and mechanical properties were evaluated in the temperature range of 110–150 °C in accordance with the requirements of GOST. The results showed that the fire resistance of textile materials treated with TEX-1 oligomeric flame retardant significantly increased. At the same time, there was no negative impact on the mechanical properties of the materials in the given temperature range, and the fire resistance indicators fully complied with the requirements of GOST. The synthesized TEX-1 oligomeric flame retardant is an effective and promising fire retardant for cellulose-based natural textile materials, which, while ensuring high fire safety, maintains the mechanical stability of the materials.
