Enhancing the Dyability of Linen Fabrics to Metal Complex Dye Using Nitrogenous Additives

摘要

Chemical modification of linen fabric via cationization with chitosan as well as Quat-188 has been recently studied. Desirable properties are imparted to linen fabric which render to the patter cationic in nature having a persistent positive charges and can thereby lead to the formation of ionic bonds salt linkages with negatively charged has no affinity for cellulosic fibers. Heriene, the former anionic dyes-class can successfully be dyed cationized linen fabric using no salt dyeing method resulting higher dye fixation as well as deep color yield (K/S), which is unequivocally due to electrostatic attraction of the dye molecules towards cationic sites in cationizated linen fabrics. The color fastness ratings of the dyed aminized linen fabrics recoverded very good results which is refer to the highly dye fixation on the modified substrate.
