The requirement of today industry is the production of desired product with less energy consumption. In textile industry, dyeing and finishing sectors consume the highest amounts of water and energy. Viscos yarns, which are one of the man-made fibers, have great effect of textile industry and it is widely used in clothing sector. On the other hand, in order to achieve a new method of dyeing, a new medium that could play an effective role as a cofactor in absorbing dye particles is needed. Treated clay nanoparticles are between among the mediums that poses such ability. Since, dyeing viscose fabrics have major constraints, improving the tonality of viscose fabrics which are treated with clay nanoparticles in order to be used in shawl production had been studied in the current study. For this purpose, viscose fabrics, which were washed with different values of clay nanoparticles’ concentration, have been treated. Thereafter, the treated viscose fabrics were dyed under the direct reactive, sulfur and dispersants dying process. Meantime, designing the dyed fabrics for being used in shawl production was also studied. Findings of the study shows that the viscose fabrics which were treated with values more than 0.5 % (o.w.b) of clay nanoparticles can improve the tonality of treated fabrics and as a consequence prevents its wastage during the Dyeing wastewater treatment.
