    SYNTHESIS AND APPLICATION OF HOMOBIFUNCTIONAL REACTIVE DYES WITH CHLOROACETAMIDE GROUPS
    (2022-01-01) Miladinova P.M.; Videnova A.A.; Georgieva N.G.
    Three new homobifunctional reactive dyes, containing two chloroacetamide groups and fragment of 4, 4’-diaminostilbene-2, 2’-disulphonic acid have been synthesized. They were evaluated on cotton and wool. The degrees of exhaustion and fixation of the dyes have been assessed. It was established that the dyes are suitable for dyeing on wool by the method exhaustion and fixation at 70°C and for cotton, using cold pad-batch method at 20°C. The photostability of the dyes in solution was studied and it was found that the dyes had a good photostability and can be recommended.
