Archroma, a global leader in color and specialty chemicals towards sustainable solutions launched Diresul® Smartdenim Blue, a liquid sulfur blue dye designed to mimic indigo at ITMA 2019.
The new product will be the core of Archroma's Indigo Reflection, a coloration system that behaves like indigo, with an even more sustainable and efficient application process compared to indigo.
With this new innovation, Archroma completes its spectrum of eco-advanced denim coloration solutions, from
this new indigo-mimicking Diresul® Smartdenim Blue which is aniline-free* and can be used in Archroma’s water-saving Advanced Denim technology, to its recent launch of the purest indigo, the aniline-free* pre-reduced liquid Denisol® Pure Indigo liquid.
Diresul® Smartdenim Blue is a liquid sulfur dye that behaves like liquid indigo in elegant neutral-green blue tone and in the most common wash-down processes.
Diresul® Smartdenim Blue has been especially designed to address the limitations of the Indicolors earlier technology. The new Diresul® Smartdenim Blue has a greener shade, better fastness to minimize back staining, and allows to create overall wash-downs much closer to actual indigo than any other dyestuff, whilst avoiding greyish cast especially in bleaching with hypochlorite.
Diresul® Smartdenim Blue can be applied in all the standard dyeing methods recommended for sulfur dyes, including pad-ox, pad-steam, exhaust, denim in all its variations (color denim, bottoming and topping of indigo), as well as in the Advanced Denim procedures (Denim-Ox, Pad-Sizing-Ox).
The innovation is the brain child of the Global Competence Center for Denim & Special Dyes experts in Archroma’s Castellbisbal plant, near Barcelona, Spain, where Diresul® Smartdenim Blue is produced.
