Advanced Denim: Synergy between Ecology, Technology & Fashion
For more than a century Indigo has been used as the principle dyestuff in the production of standard blue denim cotton fabrics. However Indigo has limited scope of effects and during the 1980s traditional Sulphur dyestuffs were combined with Indigo in toppings and bottomings to create new looks and effects.
The introduction of new Diresul RDT Indiblue dyes (Diresul Indiblue RDT-R & Diresul Indiblue RDT-G liquid) to use with Indigo or even in Indigo free applications has been a good start to offer new and special denim articles in the market.
Clariant has unveiled Advanced Denim, a new concept based on two new sulphur dyes and focusing on products, technologies and applications that are compliant with environmental aspects, health and safety standards and which fulfill the demands of style and quality performance for tomorrow's fashion.

Advanced Denim captures the essence of the unique, global end-customer love affair with denim color shades, coat & touch, magic softeners, wash-down effects and smart finishes, all of which give garments that 'added extra'.
Advanced Denim features enriched sulphur dyes through the introduction of two new Diresul RDT dyes from Clariant - Diresul Indinavy RDT-B liq, which enables deeper and faster blue shades and offers the market new and interesting effects, and Diresul Indiblack RDT-2R liq for black, grey and blue effects.
The two new products follow the successful introduction of Diresul Indiblue RDT-R and Diresul Indiblue RDT-G liquid, suitable for both Indigo and Indigo-free denim applications. The new Diresul RDT dyes enable dyeing biodegradable reducing agents as well as innovative application procedures that help to save substantial quantities of water, time and energy (Pad- Ox).
From a technology point of view, Advanced Denim offers fast-to-repetitive washing, good rubbing fastness and an easy application process. Environmentally, it features an ecological dyeing process (no hydros, less water consumption), denim that fulfills GOTS requirements, and wash-down bleaching without the need for hypochlorite (Aox free). Fashion effects include dark denim, ring denim and solid denim, along with a wide variety of shades.

ADVANCED DENIM is the result of all this Clariant work on denim application and provides the market with the most advanced solutions applying Clariant products, processes & auxiliaries.
