Abstract:IV) DYEING OF POLYPROPYLENE FIBRES WITH MONOAZO DISPERSE DYESThe monoazo disperse dyes for polypropylene fibres were synthesised. The relation between chemical structure and dyeing property of these dyes, namely influence of substituent, particularly of alkyl group, was investigated from fastness of dyeings. Aniline derivatives containing such substituents as halogen, alkyl (Cl-CB), N-alkylamino, trifluoromethyl, nitro, and amide group etc. were diazotized and coupled with alkylphenol, N-alkyl aniline, (3-naph… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
