ELENA BERCU, ION SANDU, CEZAR-DORU RADU, VIORICA VASILACHE, VASILICA TOMA, HORIA-ADRIAN ALDEA Influence of Anionic Maleic Polyelectrolytes on the Colour Parameters at Dyeing the Melana Types Fibres with Crystal Violet


Abstract:
The present study pursues the influence of polyelectrolytes based on maleic co-polymers with styrene (NaM-S) and vinyl acetate (NaM-VA) under the form of natrium salt, on the colour parameters CIE L*, a*, b* of the Melana-type polyacrylonitrile fibres dyed with Crystal Violet. The colour differences are ascribed to the modifications appeared in the colour components, in terms of concentration, polyelectrolyte character and tinctorial parameters: dyeing duration and temperature. Keywords: maleic anionic polyelectrolytes, Crystal Violet, Melana - type polyacrylonitrile fibres, colour parameters CIE L*a*b*
