Synthesis and Characterization of New Sulfonamide-Containing Anthraquinone Dyes and Their Applications to Polylactic Acid Fabric
4-Amino-N,N-diethylbenzenesulfonamide 5a and 4-Amino-N-butyl-benzenesulfonamide 5b were synthesized from aniline by using a four-step process.Then two water-soluble sulfonate-containing intermediates 7a and 7b were synthesized by use of bromaminic acid with 5a and 5b.After desulfonation of 7a and 7b,two hydrophobic sulfonamide-containing anthraquinone dyes 8a and 8b were prepared.Their structures were confirmed by FTIR,1H NMR and Mass Spectrometry.Then the sulfonamide-containing anthraquinone dyes were applied to polylactic acid fabrics by exhaust dyeing at 110 ,in which dyebath pH ℃ was adjusted to 7.We conclude that the sulfonamide-containing anthraquinone dyes exhibite good dye exhaustion and fastnesses to washing,sublimation and light on polylactic acid fabrics.
