主　　题：Modified acrylic fibers grape marc bio-colorant mordant. 

摘      要：Acrylic fibres are highly crystalline and non-polar polymers,which makes their dyeing a very difficult step that poses real technical *** order to overcome this concern,it is intended in this paper to modify acrylic fibers by different methods namely cationisation using the Crosscolor DRT then amidoximation using hydroxylamine hydrochloride and ammonium *** resulted samples were dyed then with the bio-colorant extracted from grape *** effect of the pretreatment on fibers fine structure using X-ray diffraction and the scanning electron microscope(SEM)images and its correlation with the colour strength of the dyed fabrics was *** dyeing parameters,such as dye bath pH and temperature on the performances of this dyeing process were *** dyeing qualities and new shades varying from brown to grey and dark green have been obtained following process optimization,mordanting and modification of acrylic fibers by the technique of cationisation.
