ABSTRACT:
A method for dyeing fibrous material is provided. The method includes contacting a fibrous material with a mixture of a carrier and a dye soluble or dispersed in the carrier. The improvement comprises the use, as the carrier, of a mixture comprising N-cyclohexyl-2-pyrrolidone and an alkyl or aryl benzoate. The carrier system of the present can be utilized advantageously to dye difficult to dye fibrous material such as aromatic polyamides including Kevlar.RTM. fibers and blends thereof with other fibers.
