Dyeing of polyester fibers with sulfur- and nitrogen-containing anthraquinone derivatives

A series of disperse dyes, 9,10-anthraquinone containing dithiocarbamate, thiourea and triazole fragments, were prepared via consecutive refunctionalization aminoanthraquinones in our previous studies their structures confirmed by the 1H-, 13C-NMR, IR spectra, LC-MS elemental analysis data. The obtained compounds applied on polyester fabrics exhaustion method at 130?C pH 4.0-5.0, dyeing properties evaluated color measurements, washing fastness test light test. Many these dyes gave solid level dyeings fabric with low % concentration dye. dyed samples displayed very good fastnesses. change staining results quite ratings ?4-5? or above. also satisfactory for most samples.
