ADSORPTION OF PLANT EXTRACTS ON CATIONIZED COTTON
Cotton, like most textile fibers, is negative charged in neutral and alkali aqueous solutions. Dyestuffs, optical brighteners and finishing agents in aqueous solution have the same electrical charge as cotton. Therefore, adsorption processes are difficult due to these repulsive forces. This paper studies the application of water extraction plants of St. Johns wart, marigold and hibiscus for the finishing of modified cotton – by mercerization and cationization. The mercerization is the oldest modification since 19th century, while the cationization is researched in last 10 years. In this paper cationization of cotton fabric for achieving electropositive charge and better adsorption properties was carried out with cationic compound, quaternary ammonium salt during the mercerization well as with commercial product for cationization Denimcol Fix-GF (Bezema). The cotton electrokinetic phenomena after modifications were determined by zeta potential, isoelectric point, point of zero charge and specific amount of surface charge. The adsorption ability of plant extracts with and without mordant was investigated.
