Abstract
A method for treating natural textile fibres and synthetic polyamide fibres to enhance their affinity for disperse dyestuffs which comprises treating the fibres with an aqueous solution or dispersion of an arylating agent. The arylating agent contains both a benzene or naphthalene ring and a reactive group, such as a halo-triazine group. The fibres may be treated by exhaustion from long liquors or by padding, and the affinity for disperse dyestuffs is considerably increased thereby.
