Synthesis and Applications of Dye Fixing Agent FHAD

YANG Ju-ping (Zhejiang Polytechnic College, Hangzhou 310033)  
Polyamine was synthesized by the reaction of methylamine with epoxy chloropropane at pH=6,65℃for 2 hours, then the product was polymerized with dimethyl-diallylamine hydrochloride, giving a complex fixing agent FHAD for reactive dyes. If the fixing agent FHAD fixed at 50℃ for 20 minutes, the fixation of reactive dyes would have improved by 25-66%, and their color (washing) fastness promoted from 3 to 5.
