Abstract

In this research, dyeing ability of the chitosan grafted-acylated wool fabrics has been studied. Acylated wool fabrics at two different solvents (dimethylsulfoxide (DMSO) and N,N-dimethyl formamide (DMF)) using succinic anhydride (SA) and grafted with chitosan have been dyed with acidic dye Polar Brilliant Red 3BN. Chitosan grafted fabrics indicated the higher K/S in comparison with the acylated and blank wool samples.
