A PPLICATION of the paste containing the dyes to the required areas on the fabrics is designated as direct printing, consequently dyeing and steaming followed by washing to remove any residues. In pigment printing, the pigments and cured binder adhere to fabric surface with the cured binder film. No further treatment is required. Direct printing is considered the most important printing. Fibers have been defined by the textile institute as units of matter which are characterized by fineness flexibility and high ratio of length to thickness. Fibers are the basic unit from which all textile materials are made. Textile goods are manufactured from fibrous material which may be either of natural or man-made origin.
D EGRADATION of hardly degradable textile dyes in wastewater using dielectric barrier discharge (DBD) plasma method becomes a competitive technology for primary decomposition. In the same trend, new complex Dielectric Barrier Discharge Plasma device has been used in this study to evaluate its results in degradation of textile dyes. The six dyes used are from different classes (acid, basic and reactive) and structure to cover all the bases of dye. Different parameters as exposure time, ozone and dye concentration and their effect on% efficiency (η) of color removal of dyes from their solution were investigated. The decolorization kinetics and both chemical oxygen demand (COD), the effect of final product of the degradation process on the aquatic live is expressed using biological oxygen demand (BOD) analysis. The resultant study shows that, the maximum color removal was obtained by treating the dye solution for 90 sec using ozone concentration 20g/m 2 and concentration of dye 0.5g/l for all the dye. Kinetic studies were been also considered and the obtained results were following first-order reaction.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
