<p>A process of simultaneously dyeing and flame retarding an aramid fibre, comprises the steps of: (1) contacting dyeable poly(m-phenylene isophthalamide) fibres or fabric with a solution consisting essentially of a flame-retarding amount of a cyclic phosphonate ester flame retardant represented by the formulae: <CHEM> where a is 0 or 1; b is 0, 1 or 2, c is 1, 2 or 3 and a+b+c is 3; R and R<1> are the same or different and are alkyl (C1-C8), phenyl halophenyl, hydroxyphenyl, tolyl, xylyl, benzyl, phenethyl, hydroxyethyl, phenoxyethyl, or dibromophenoxymethyl; R<2> is alkyl (C1-C4); and R<3> is lower alkyl (C1-C4) or hydroxyalkyl (C1-C4); or <CHEM> where d is 0, 1 or 2; e is 1, 2 or 3; R<2> is alkyl (C1-C4); R<3> is lower alkyl (C1-C4) or hydroxyalkyl (C1-C4); R<4> is alkyl (C1-C4) phenyl, halophenyl, hydroxyphenyl, hydroxyethyl, phenoxyethyl, dibromophenoxyethyl, tolyl, xylyl, benzyl, or phenethyl; and R<5> is monovalent alkyl (C1-C6), chlorophenyl, bromophenyl, dibromophenyl, tribromophenyl, hydroxyphenyl, naphthyl, tolyl, xylyl, benzyl, or phenethyl; divalent alkylene (C1-C6), vinylene, o-phenylene, m-phenylene, p-phenylene, tetrachlorophenylene (o, m, or p), or tetrabromophenylene (o, m, or p); or trivalent phenenyl and a disperse dyestuff, an acid dyestuff or both; and (2) heating the aramid fibre treated in step (1) to fix said dye to said fibre. 1</p> |
