The feasibility of dyeing aromatic polyamides (aramids) in order to produce high colour fastness is examined. Experiments have shown that m-aramids can be dyed with acid, metallic complex and disperse dyestuffs, though the light fastnesses are not greater than those obtained with the basis process. Ammonia pretreatment leads to improved dyeability with a basic dyestuff and fastnesses as good as those obtained with swelling agents.
