A NOVEL ECO-FRIENDLY DYEING OF CATIONIZED POLYESTER FABRICS USING CURCUMIN NATURAL DYE
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 5, Issue 11
Abstract
Due to the cheap in prize, high production and long life of polyester fabrics, its application is wide in apparel industry. But, concerning to their hydrophobicity and soiling properties it makes the wearer for less comfort. This is because of the absence of water absorbing group in it. This work presents an ecofriendly method for dyeing polyester fabrics with curcumin natural dyes. Firstly alkali treatment of the substrate were done then cationization to activate fibers and improve dyeability of polyester. Fabrics are pretreated with different concentrations of chitosan for different periods of time. Dyeability of the treated samples was investigated in terms of their colour strength expressed as K/S in addition to fastness to washing and light.
