Dyeing performance of a new disazo disulphide bis(ethylsulphone-monochlorotriazine) reactive dye on cotton

A novel disazo reactive dye of a temporarily high molecular structure containing disulphide bis(ethylsulphone-monochlorotriazine) reactive system has been synthesised and applied to cotton. By virtue of the characteristic disazo disulphide bis(ethylsulphone) dye structure, a good substantivity was observed at the neutral exhaust dyeing conditions. Subsequently, the results assessed for the alkaline dyeing conditions indicate that the dye vinylsulphone-monochlorotriazine reactive system confers a high fixation efficiency for this type of disazo reactive dye. The results also indicate that the high fastness properties were obtained.
