ABSTRACT:
A process of printing a predetermined pattern on and improving the flame resistance of a poly(m-phenyleneisophthalamide)-containing textile fabric including the successive steps of: (a) applying a print paste, composed of a highly polar solvent selected from dimethylsulfoxide, N,N-dimethylacetamide, N-methyl-2-pyrrolidone, and mixtures thereof, the polar solvent adapted to swell the aramid fiber and introduce a dyestuff therein, at least one organic dyestuff that is soluble in the polar solvent, a print paste thickening agent compatible with both the polar solvent and the dyestuff, a flame retardant and water in a predetermined pattern onto the surface of the aramid textile; and (b) drying and curing the thus printed fabric at an elevated temperature sufficient to permeate and fix the dyestuff and the flame retardant molecules inside the aramid fibers.
