Abstract

Indigo dye has been widely used for dyeing traditional blue denim products intended to give a worn faded look. However while using the warp yarn dyeing process with indigo dye often occur problems of colour variation. To prevent colour variation, controlling the indigo dye baths is an important factor The objectives of this study include adjusting dosages of leuco indigo, hydrosulphite, pH (caustic), using an automatic measurement and dosing system taking redox titrations as the basis. It was observed that measurements carried out with this system became more reliable and also had a positive effect on the quality of the product.
