ARCHROMA to introduce new eco-advanced "indigo clone" solution

Archroma, a global leader in color and specialty chemicals towards sustainable solutions, has recently launched at the ITMA exhibition its new Diresul® Smartdenim Blue, a liquid sulfur blue dye designed to mimic indigo.

Diresul® Smartdenim Blue liquid was developed in compliance with “The Archroma Way: safe, efficient, enhanced, it’s our nature”. The approach finds its origin in Archroma’s deep belief that it is possible to make the textile industry sustainable, economically and ecologically.

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.

The sulfur-based Diresul® RDT Indicolors dyes have been introduced by Archroma back in 2007 to offer a water-saving alternative to indigo for blue denim, especially when applied with Archroma’s recommended Advanced Denim application processes, Denim-Ox and Pad-Sizing-Ox.

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.

Diresul® Smartdenim Blue meets the requirements of the major brand and retailer manufacturing restricted substances list (MRSL) and eco-labels such as C2C**, and it is aniline free*.

“In the current context of tight availability of indigo precursors,” says Albert Llort, Head of Archroma’s Global Competence Center for Denim & Special Dyes, “Archroma offers with Diresul® Smartdenim Blue an alternative dyestuff to create new blue denim articles that is aniline-free* and light in water consumption, but also offers a reliable supply source. Because it’s our nature!”

Circ and Huafon partner to scale textile-to-textile recycling in China

Circ® and Huafon, a leading spandex producer in China, are partnering to build and scale a new multi-phase textile-to-textile recycling site in China, expanding Circ's global pathway to industrial scale. The project will be located within Huafon's industrial footprint and will use Circ's technology to process polycotton textile waste and recycle both inputs, recovering recycled PTA, recycled MEG and recycled cellulosic pulp for use in new textiles. The site will be developed in phases, with Phase 1 designed for approximately 200 metric tons of textile waste per day and additional capacity planned.

An eco-friendly alternative to fluorocarbon treatments

Protective and outdoor clothing derives its durable water-, dirt- and oil- repellent properties from the application of fluorinated polymers or per- and polyfluorinated low-molecular- weight chemicals (PFCs). The beneficial properties thus achieved on textiles are offset by environmental and human health risks. For manufacturers of sports, medical, protective and automotive textiles, researchers at the Sächsisches Textilforschungsinstitut e.V. and the Leibniz Institute for Polymer Research have developed liquid-applied dispersions and solutions to functionalise textiles without the use of fluorine.
