Abstract: The effect of grafting on the light fastness of cationic dyeings on nylon and basic as well as reactive dyeings on wool has been investigated. Cationic dyes were applied to nylon after chemical modification to increase the number of acidic sites. Grafting was done by γ-ray irradiation in the presence of acrylonitrile and acrylamide to get low add-on (< 3%) to maintain the physical and mechanical properties of the dyed fibres. With acrylonitrile, the light fastness of dyeings was improved appreciably, while acrylamide gave only a marginal improvement.
