Deakin/Xefco: Dyeing jeans without a drop of water

Deakin University has signed a partnership agreement with Geelong-based company Xefco as part of its Recycling and Clean Energy Commercialisation Hub (REACH) to conduct new research to transform how our clothing, including jeans, get their colour.

Jeans are one of the most worn garments in the world, but they are also one of the least environmentally friendly, taking around 75 litres of water to dye just one pair.

Deakin’s work with Xefco is helping to explore if a waterless manufacturing process can replace the water intensive processes the clothing industry has used for hundreds of years. The new technology in development is called ‘Ausora’.

Associate Professor Alessandra Sutti, from Deakin’s Institute for Frontier Materials, said it was exciting to be on the commercialisation journey with Xefco, working with the company to discover what is possible and hopefully reduce the world’s fashion footprint.

“If successful, the Ausora technology, which colours fabrics without the need for large quantities of water, will put us a step closer to more efficient and sustainable clothing manufacturing,” Associate Professor Sutti said.

Xefco CEO Tom Hussey said the company’s new pilot plant, housed at Deakin in Geelong, will test different materials, including specialised fabrics such as waterproof items like outdoor jackets and jeans.

“This is the first stage of Xefco’s vision for the technology, with the REACH project focused on demonstrating the commercial viability of the technology at pilot scale and developing processes so it can be scaled up for commercial production,” Mr Hussey said.

“Together, Deakin and Xefco will push the limits of innovation and see what is possible.”
Xefco’s pilot plant is co-located with Deakin researchers at ManuFutures, the state-of-the-art advanced manufacturing hub at Deakin’s Waurn Ponds campus.

Founded in 2018 Xefco now employs 17 people and its products are already making a difference across the world. Its XReflex technology, which reduces consumption of insulation materials, is being used by some of the world’s leading apparel and fashion brands including The North Face.

Backed by a $50 million grant from the Australian Government’s inaugural Trailblazer Universities Program, with industry and university support taking the total project value to $380 million, REACH is facilitating the development of greener supply chains and accelerating business success as markets move from a throughput economy to a circular economy.

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.

Archroma and Jeanologia launch ‘Pad-Ox G2 Cold’, a water-saving dyeing process

Archroma, a global leader in specialty chemicals towards sustainable solutions, and Jeanologia, a world leader in sustainable and efficient technology development, today announced the launch of ‘Pad-Ox G2 Cold’, a water-saving dyeing process at room temperature for casual looks.

Archroma initially introduced its eco-advanced Pad-Ox dyeing process for woven fabrics, and then used it as part of its ADVANCED DENIM concept. By combining the oxidation and fixation steps, it is possible to shorten the dyeing process and thus realize substantial resource savings in water, wastewater, cotton waste, and energy.

Over the years the company has worked with its textile manufacturers and partners to improve the Pad-Ox process, in particular woven applications such as chinos and casual wear. To achieve maximum positive impact, Archroma is using its Diresul® range of low sulfide sulfur dyes and, more recently, its innovative plant-based range of EarthColors®. A wide selection of dyes from these two ranges have received the Cradle-to-Cradle Product Innovation Institute’s Platinum Level Material Health Certification.

Meanwhile, Jeanologia has been working on the technology side, with laser and eco-finishing solutions for more than 25 years, accompanying the textile industry on their way to producing with zero discharge. In 2008, the company introduced its G2 Dynamic the first ozone treatment for continuous fabric that dramatically reduces the amount of water and chemicals used, while at the same time saving costs at the mill and eventually at the garment finishing facilities. This technology makes fabric more stable and consistent and prepares the fabric better for the use of other technologies like laser. This machinery can be used along with Pad-Ox technology to help cleaning fabric thus improve fastness results. While it allows process to work at room temperature.

Project focus on water saving
Archroma and Jeanologia therefore understandably decided to team up and combine their expertise in sustainable dyeing and finishing technologies. The objective of the project was to improve the Pad-Ox dyeing process even further, in particular in one area that still offered room for positive impact: temperature and fastnesses.

The new ‘Pad-Ox G2 Cold’ dyeing process works thanks to the insertion of very small machinery into the existing finishing range process, using cold processing and thus operating with much less water, carbon footprint and energy than traditional benchmark fabric finishing processes, whilst retaining the water and other resource savings offered by the Pad-Ox technology.

Maximum savings can be achieved by mills and garment manufacturers who wish to switch from a conventional dyeing process straight to ‘Pad -Ox G2 Cold’ to obtain high quality fabrics for comfortable and casual wear.

How to do more with less explored at Kingpins24 Flash

  • Major Monforts denim customers continue to pioneer new initiatives that are pushing the boundaries of sustainable production.

Recycling their cotton waste has become one way these companies can do more with less, and at the recent Kingpins24 Flash online event, Sedef Uncu Aki, director of Orta, headquartered in Istanbul, Turkey, announced a new partnership with leading recycling operation Gama Recycle.

Traceable
“Through this local partnership we will supply the waste from our spinning mills and return around 3,000 tons of premium quality cotton back to them,” she said. “We have established a truly controlled and traceable system and partnering with a domestic recycling centre is important because a lot the carbon emissions associated with recycling usually come from transportation.”

Orta’s ZeroMax range meanwhile uses no cotton at all, being based on Lenzing’s Tencel cellulosic fibre, while the company’s involvement in denim production for a recent launch by Levi Strauss, of jeans made with organic cotton and Circulose – a breakthrough material developed by re:newcell of Sweden and partners – was hailed as a further step forward.

To make Circulose, re:newcell repurposes discarded cotton textiles, such as worn-out denim jeans, through a process akin to recycling paper. The incoming waste fabrics are broken down using water. The colour is then stripped from these materials using an eco-friendly bleach and after any synthetic fibres are removed from the mix, the slurry-like mixture is dried and the excess water is extracted, leaving behind a sheet of Circulose. This sheet is then made into viscose fibre which is combined with cotton and woven into new fabrics.

Circular Park
Omer Ahmed, CEO of Artistic Milliners also announced plans for his company’s new 70,000 square-foot Circular Park in Karachi, Pakistan, at Kingpins24 Flash.

Once complete, this will add three million square metres of additional denim capacity a month to the company’s production and take its total recycled output to a monthly five million metres.
Ahmed observed that there is currently a lack of sustainable fibres that are readily available to use for denim production at scale.

“Organic cotton is too expensive, and in my opinion always will be,” he said. “Cottonised hemp is also not cheap and it’s hard to mix with cotton, while the new regenerated cellulose fibres that are now emerging are promising, but currently in short supply. Recycled polyester is meanwhile still based on petroleum resources which we want to move away from. As a consequence, there are only a few other options for us as a manufacturer and this new project will help us minimise our own waste while significantly lowering our carbon footprint.”

Other Monforts denim customers to introduce cotton fibre recycling operations at their plants recently include AGI Denim, Bossa and Soorty.

Vertical savings
Refresh is the name of the latest collection from AGI Denim – reflecting the company’s significant reduction in water consumption.

The company has just opened new fibre spinning and denim mills at its complex in Karachi, Pakistan.

“Over the years we’ve gone through a series of backward integration steps to become fully vertical,” said AGI Denim executive director Ahmed Javed, at Kingpins24 Flash. “In our latest expansion, we revisited every step of the production processes in order to make resource savings.”

Innovations have included the installation of proprietary robotics for garment finishing, but the most attention has been paid to water savings.

“Pakistan is one of the largest cotton-producing companies in the world and we’re fortunate that the type of cotton that is grown here is well suited to denim production and also helps us lower our carbon footprint, with everything done in close proximity,” Javed said. “In the lifecycle of a pair of denim jeans, however, cotton fibre production contributes 68% of water consumption. While we cannot control how much water cotton needs for it to grow, we can rethink the way we use it in our factory.”

Refresh-branded denims are washed from 100% recycled water as a result of the company’s new wastewater treatment plant, which puts production wastewater through a series of steps beginning with equalisation, followed by aeration and concluding with sedimentation. The water travels through filtration and ultrafiltration systems before being subjected to an activated carbon system and finally a reverse osmosis system to reduce any dissolved salts.

AGI now recycles 4.4 million gallons of water each month – enough to wash a million pairs of jeans.

Sustainable
Monforts has a leading position in the field of denim finishing with its well proven Thermex continuous dyeing systems, Montex stenter dryers and other lines for resource-efficient and economical processing.

“Our denim partners are constantly setting themselves new goals in respect of sustainable production – and more importantly, achieving them,” says Hans Wroblowski, Monforts Head of Denim. “We work closely with them with the aim of constantly optimising processing parameters and achieving further savings in energy, water and raw materials throughout the dyeing and finishing stages of production.”

The latest Monforts innovation for denim is the CYD yarn dyeing system. This technology is based on the effective and established dyeing process for denim fabrics that is now being applied for yarn dyeing. The CYD system integrates new functions and processes into the weaving preparation processes to increase quality, flexibility, economic viability and productivity. A full CYD line is now available for trials at the company’s Advanced Technology Centre in Mönchengladbach, Germany.”
