ABSTRACT:
Textile treating compositions containing the elements phosphorus, nitrogen, and bromine and the processes for imparting flame resistance to organic fibrous materials have been prepared. This is accomplished by impregnating the textile treating compositions consisting of (1) tris(hydroxymethyl)phosphine mixed with nitrogenous compounds containing at least two members of the group hydrogen and methylol radicals (--CH.sub.2 OH) attached to trivalent nitrogen atoms, or (2) soluble methylol phosphine adducts which contain one or more methylol phosphine radicals (P--CH.sub.2 OH) prepared by reacting tris(hydroxymethyl)phosphine with an amide or amine which contains one or more hydrogens attached to a trivalent nitrogen with an organic bromine containing material with at least 10% bromine in the form of bromine atoms attached to carbon atoms, in proportions selected so that generally the phosphorus contained in structures of the group (--CH.sub.2).sub.3 P amounts to a small portion of the total weight of the mixture, and heating to cause insolubilization in or on the fibrous structure.
