摘要： A method for dyeing fibrous material is provided. The method includes contacting a fibrous material with a dyebath comprising a mixture of a dye assistant and a dye soluble or dispersed with dye assistant in the dyebath. The dye assistant comprises a salt of a low molecular weight aromatic sulfonic acid, and can include a low molecular weight surfactant. The dye assistant of the present invention can be advantageously utilized for dyeing difficult to dye fibers such as aromatic polyamide fibers, polybenzimidazole fibers and aromatic polyimide fibers.

摘要： A method for dyeing fibrous material is provided. The method includes contacting a fibrous material with a carrier and a dye soluble or dispersed with the carrier in a dyebath. 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.
