Presentation of different cellulosic yarn spinning wastes for decolorization of a basic dye solution

Waste management and reuse have now become the trend topics because of the demand to the comfortable survival of human being. For the cleaner production these two approaches have of great importance. Waste management and reuse consists many activities containing production and consumption of the goods and services. Here in this study, the wastes from a cotton yarn spinning line (mostly containing cotton fibers, seed coats etc.) were collected and characterized then they were used in decolorization of a dye solution containing a cationic (basic) dye. Before using the wastes, the wastes were dried at different temperatures for different durations, and these wastes were used as dye-adsorbing materials, such as those not previously treated with heat. As a result, it was determined that the adsorbents constituted of the spinning mill wastes had the ability to adsorb the dye from the dye solution. It has also been found that the heat pretreatment has an effect on the color removal efficiency of the wastes. By this way, it has been tried to introduce a process that uses waste from the spinning mill to remove the color of textile dye wastes containing basic dyes.
