Archroma, G-Star RAW and Advance Denim promote cleaner denim production

With the aim to help the denim industry reduce the environmental impact of its wastewater and move towards circularity, Archroma, G-Star RAW and Advance Denim have renewed their joint commitment to the production of aniline-free denim apparel based on Archroma’s DENISOL® PURE INDIGO 30.

Their joint aim is to produce high-quality denim in authentic blue shades without the aniline impurity carried through from the synthesis of standard synthetic indigo. In traditional denim production, this aniline remains bound with the indigo pigment on the fabric; the remaining aniline is discharged during the dyeing and washing process. This can be a problem because aniline is toxic to aquatic life and two-thirds of aniline waste currently ends up in wastewater discharge where it could potentially pollute waterways and the ocean.

Archroma developed DENISOL® PURE INDIGO 30 to answer this key challenge. A 30% pre-reduced indigo solution, DENISOL® PURE INDIGO 30 makes it possible to produce indigo-dyed denim without aniline impurities throughout the process.

Easy to use with automated dosing, DENISOL® PURE INDIGO 30 reduces the water needed for preparation, washing and wastewater treatment compared to indigo grains. It also reduces hazardous chemical consumption while allowing high reproducibility and creating the authentic and iconic deep indigo shades traditionally associated with denim.

G-Star RAW is working towards making 20% of its entire collection from Cradle to Cradle Certified® fabrics by 2025. Its partnership with Archroma and Advance Denim contributes to this goal, since the aniline-free DENISOL® holds a Gold Level Material Health Certificate from the Cradle to Cradle Products Innovation Institute. DENISOL® PURE INDIGO 30 is also compliant with other eco-standards and the requirements of leading retailers and brands.

Advance Denim, G-Star RAW and Archroma have previously collaborated to launch collections based on Archroma’s EarthColors® technology, which upcycles plant waste from the herbal industry to create sustainable colorways.

CHT Gruppe launcht neue Marke für Jeans- und Garmentbehandlung

Die ökologischen und sozialen Bedingungen bei der Herstellung von Textilien rücken in den Vordergrund und in das Bewusstsein der Industrie- und Endkunden. Mit der neuen Marke LAB102 möchte das „Jeans & Garment“-Team der CHT Gruppe ihren weltweiten Denim-Kunden zukünftig nachhaltige chemische Lösungen und Technologien anbieten.

Woher kommt der Name „LAB102 – Blue veins of CHT“?
LAB wurde nicht nur gewählt, weil das englische Wort für Labor perfekt zu einem Chemieunternehmen passt, sondern auch, weil es für Innovation, Entwicklung und Entdeckung steht. Die Ziffern 102 im Namen verweisen auf die Hausnummer der CHT-Unternehmenszentrale in Tübingen.
Der Slogan "Blue veins of CHT" hält die Verbindung zu dem in der Branche bekannten Namen CHT aufrecht. Zudem ist die Denim- bzw. Jeansindustrie traditionell und historisch gesehen Indigo – also blau.

Nachhaltigkeit im Fokus
Nicht nur die Chemie, sondern auch die Technologie steht bei LAB102 im Fokus. Vernebelungs-, Laser- und Ozontechniken sind Innovationen, die aktuell neue Wege in der Jeans- und Garment-Behandlung ermöglichen und sich auf einem hohen ökologischen Niveau bewegen. Ihre Verwendung kann zu Einsparungen an Wasser und Energie führen. Auch der Einsatz von Chemikalien kann reduziert werden, wenn Prozesse optimiert und an die neuen Anforderungen angepasst werden. Dafür arbeitet das „Jeans & Garment“-Team der CHT Gruppe bei Neuentwicklungen weltweit mit den führenden Maschinenherstellern zusammen.

DyStar Celebrates 125 Years of Indigo Excellence

The story started with a huge market demand for the industrial synthesis of Indigo during the late nineteen century. The first Industrial Synthesis of Indigo, Indigo Pure BASF, was successfully manufactured and introduced into the market by BASF in July 1897. It was a significant achievement for the German Chemical Industry.

Over the years, the product has made revolutionary changes to the supply chain. New technologies enabled the transformation of Synthetic Indigo Powder application to pre-reduced DyStar® Indigo Vat 40% Solution. Being the pioneer in the market, the pre-reduced solution set an important industry milestone when it was first launched in 1998.

DyStar’s innovation remains a core catalyst in our chemistry research and development journey. When the DyStar® Indigo Vat 40% Solution was introduced, the core intelligence lies behind the benefits from Sustainability to Health and Safety. The technology transforms Indigo into its soluble Leuco form, making the Indigo dyeing process more sustainable, efficient, and stable in production. In addition, workers in Denim Mills can be assured of product safety as well.

Similarly, in recent modules under Cadira® Denim, DyStar introduced the first salt-free Indigo dyeing process in history. The applied technology completely eliminates hydrosulphite in the application of Indigo.

Archroma and Stony Creek Colors produce plant-based pre-reduced indigo

Archroma and Stony Creek Colors (“Stony Creek”), a manufacturer of traceable natural indigo dyes, announced that they have entered a strategic partnership to produce and bring to the market Stony Creek’s IndiGold™ high-performance plant-based pre-reduced indigo at scale.

Stony Creek extracts its dye from proprietary Indigofera plant varieties grown in partnership with family farms as a regenerative rotational crop.

Stony Creek Colors developed the new IndiGold™ concept as on of the world’s first pre-reduced natural indigo dyes, which was then developed with Archroma to offer a plant-based alternative to synthetic pre-reduced indigo. The dyestuff will be sold as a 20% concentration in a soluble liquid form that displays similar performance to comparable synthetic indigo products available on the market.

Stony Creek Colors evolved into an innovative leader in plant-based indigo due to its complete development of an improved agricultural value chain, from seed breeding and production to biomass harvest and extraction. The company has been selling its US grown indigo to denim mills since 2015.

The pre-reduced plant-based indigo partnership took root in 2020 when Stony Creek was looking to work with like-minded partners to produce the new dyestuff at scale. Archroma emerged as the ideal partner as the company is well known for its expertise in indigo manufacturing and application, as well as for its commitment to transform the denim industry towards creating better blue jeans.

Archroma immediately offered to support the idea of Stony Creek Colors with extensive pilot scale manufacturing trials and engaged with its network of denim machinery manufacturers to test the first samples in industrial conditions. The trials showed excellent coloration and the typical indigo wash down, as with synthetic indigo. Archroma will produce the first batches of IndiGold™ in Salvatierra, Mexico, and has other locations where the product could be made. The company will support Stony Creek Colors through its manufacturing and logistics capabilities, and its expertise in denim dyeing with customers using pre-reduced indigo.

While this development was underway, the global innovation platform Fashion for Good selected Stony Creek Colors as an innovator in its global Innovation Program. The program connects brands with innovators to work together to test, validate and ultimately scale disruptive innovations in the fashion industry to drive positive impact. Through the program, Fashion for Good facilitated a collaboration between brand partner Levi Strauss & Co. and Stony Creek Colors which was announced in December 2021. The partners will pilot the use of IndiGold™ in denim mills at scale, with the goal of unlocking key learnings around shade application and other efficiencies of this new dyestuff.
