|Title:||Interaction of direct dyes with cationic dye fixing agents|
|Keywords:||Direct dyes;Dye fixing agent;Interaction|
|Abstract:||An attempt has been made to investigate the interaction of four direct dyes possessing varying number of solubilizing groups with four commonly used dye fixing agents of amine-formaldehyde condensate type of product in aqueous solution. These studies will help to evaluate different types of dye fixing agents for obtaining better wash and perspiration fastness of the dyed samples. The results indicate that interaction depends on the nature, concentration and functional groups of dye fixing agents. Also, the sulphonate and other groups present in the dye molecule such as -OH, -NH2, -COO- also contribute to the interaction with dye fixing agents.|
