Optimization of cost in manufacturing of Reactive dye

Abstract :

Fiber reactive dyes are important in dyeing textiles because they are unequally in their ability to confer ight wet fast shades on cotton faic. While fiber reactive dyes are commonly employed for this purpose, the use of these dyes can introduce high costs and environmental concerns. For example, their fixation levels can be as low as 50% and high salt levels are typically needed to achieve desired shades. ?us, a mechanism for increasing fixation and exhaustion efficiencies in an economical way would enhance the value of these dyes to the textile industry. With these points in mind, studied a reactive dye modification that holds promise for achieving desirable exhaustion and fixation efficiencies. Specifically, the reactivity and affinity of some widely used reactive dye. In laboratory dyeing studying it was determined that modified dye gave the best results in affinity and shade depth assessments. It remained to be shown that these dye could be applied in an industrial dyeing setting. ?is thesis research focuses on applying the modified dye in a Commercial–scale manufacturing setting in order to further assess the benefits of the modified dye. In preliminary studies, laboratory–scale dyeings were conducted to further investigate the color strength relationships between the modified and commercial dyes. An optimized batch dyeing procedure was developed for the application of the modified dye, including optimal temperature, salt and alkali concentrations, time, and bath ratio. It is clear that high fixation levels and deep shades are obtained using the modified dye at lower dyeing temperatures and salt levels than commonly employed for the commercial dyes.
