An innovative method for reducing water use in process after dyeing

Abstract

Textile industries consume large volumes of water and chemicals for wet processing of textiles. Textiel wastewater damage the environment as they contain high concentrations of organic and inorganic chemicals. There is also a lot of waste water and energy consumption while processes. Reactive dyes react with cellulose to establish covalent bond and are water soluble. Because of these properties and low fix rates, they cause high levels of dyes in waste water. Reactive dyes which are not totaly fixed to the fabric throughout the dyeing process. Washing is required to remove un-fixed dye from the fabric, The control of water pollution has become of increasing importance in recent years. The control of water pollution has become of increasing importance in recent years. The release of dyes into the environment constitutes water pollution. Since conventional treatment methods are insufficient for purifying dyehouse wastewaters, new treatment technologies are developed and applied for its treatment. Nowadays, removal of dyes methods are often very costly and have many problems. For this reason, effective and economical alternative treatment methods are needed in removing large amounts of dyes from waste water. In this study, it is aimed to reduce the number of washing treatment after direct and reactive dyeing. It is planned to develop filters made from cationic fibers while the use for after treatment processes. When experiments are done, we observed that non-hydrolysis of the dyes trapped into the developed filters. As a result of these study, the wastewater likely to show better results such as; less energy and, less water consumption has been achieved.
