The fire-retardant properties of modified polyacrylonitrile fibers with phosphorus-containing polymers, as well as nitrogen and brominecontaining flame retardants, have been studied. It has been shown that, in contrast to low molecular weight fire retardants, polymer and oligomer fire retardants give fibers higher fire-retardant properties. The results of determining the flammability of samples showed that the treatment of polyacrylonitrile fibers with oligomeric flame retardants based on the developed flame retardants improves the fire-retardant properties of fibers and materials based on them. As a result of comprehensive research, it was established that for the manufacture of fire-resistant material it is advisable to use the optimal ratio of “polyacrylonitrile fiber - fire retardant”. Carrying out fire-retardant treatment of polyacrylonitrile material with compositions of 3-chloro-1,2-hydroxypropane with 2,4,6-triamino-1,3,5-triazine makes it possible to obtain fabrics with a reduced fire hazard and with the required strength parameters. Also, in the work, based on kinetic and spectroscopic studies and taking into account literature data, a mechanism of oligomeric fire retardant is proposed, which gives fibers and textile materials special fire resistance properties.
