- W2380451199 abstract "A new universal dye containing two naphthalene rings was prepared by condensation of 7-aceta- mide-4-hydroxy-2-naphthalene sulfonyl chloride with N,N-dimethylethylenediamine, followed by the coupling reaction with ammonium of m-amino-benzene-β-hydroxyethylene sulfonate. The chemical structures of the new dye and the intermediate were confirmed by Mass Spectrometry, 1H NMR and 13C NMR analyses. By adjusting the pH value of the dyebath and adding textile auxiliaries, the synthesized universal dye was applied to dye cotton, wool, silk, nylon, acrylic and PET fabrics without conducting other chemical reactions outside the dyebath. The exhaustion rates of dye on the fabrics aforementioned were 6.2%, 59.8%, 44.7%, 33.5%, 11.1% and 9.2%, respectively, which reveals that the dye has good affinity for wool, silk and nylon fabrics. The washfastness grades of dyed wool, silk and nylon fabrics were all higher than 3, while their lightfastness properties were not satisfactory." @default.
