چکیده
|
Novel bisazo dichloro-s-triazinyl (dct) reactive dyes (5a-h) containing 1,3,4-oxadiazole molecule as a tetrazo component were synthesized and applied on silk,wool and cotton fibers by exhaust dyeing method. the structures of these dyes were confirmed by uv-vis,ft-ir,1h and 13c nmr and elemental analyses. the exhaustion,fixation and fastness properties of the dyed fabric were assessed and the results demonstrated that these dyes showed moderate to very good light and good to excellent washing and rubbing fastness properties. the colorimetric data (l*,a*,b*,c*,h*,k/s) of these dyes have also been studied in detail. © 2011.
