Sttudies on Synthesis of Bifunctional Reactive Dyes and Their Application on Silk, Wool and Cotton Fibres

摘要

Various bifunctional reactive dyes have been prepared by diazotised acid components such as Bronner acid, K-acid, Sulfotobias acid, Metanilic acid, J-acid, Peri acid, Laurent acid, Tobias acid, Chicago acid and 4-amino toluene 8-sulphonic acid and coupling with 4,4#min#-methylene bis-o-anisidine cyanurated H-acid and their dyeing performance on silk, wool and cotton fibres has been assessed.
