Abstract
The behaviour of heterobifunctional reactive dyes, containing a monoch lorotriazine and a vinyl sulphone group, on silk has been investigated . Maximum exhaustion and fixation were obtained in a neutral medium at 90 degrees C. The addition of sodium sulphate was found to promote th e exhaustion of reactive dyes at pH values above the isoelectric point of silk. A reduction in the solubility of dyed silk indicated that cr osslinks were formed with bifunctional reactive dyes.
