Abstract
The invention refers to area of chemical technology of fibrous materials, in particular, to reception of fire-resistant textiles by a method of processing of the latter by the compositions containing nitrogen and phosphorus. Technical result of the invention is increase of efficiency of procession. The method provides permeating a starting material by water solution of organophosphorous compound, drying, processing by ammonia, as the compound is used a precondensate of chloride tetrakis oxy methyl phosphon and urea at a molar parity between an ion tetrakis oxy methyl phosphon and urea 1:0,5. The specified process is repeated in two stages.
