The carrier comprises an N-substituted aromatic carbonamide or an N,N-disubstituted aromatic carbonamide or mixture thereof. The carrier system of the present can be advantageously utilized for improving dye and flame resistant properties of difficult to dye fibers such as aromatic polyamide fibers, polybenzimidazole fibers and aromatic polyimide fibers.
