From the Sector

• 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.”

Decision SA, part of the leading European composites consortium, Carboman Group, and a specialist in the development, prototyping and production of large composite structures, is proud to announce a new direct mould tooling technology for aerospace.  Decision’s latest tooling solution provides OEMs and manufacturers with short lead times for highly stable direct moulds for series production both in and outside of the autoclave at temperatures of up to 180˚C.

Decision and Carboman recently delivered the first customer moulds using the new technology, providing a tooling glass prepreg, stainless-steel backed direct female mould tool created for the series production of a Class 3 fairing to a leading European aerospace OEM. Decision has immediate availability and capacity for similar tooling projects with lead times currently as short as six to eight weeks.

With no traditional plug or mould pattern required, Decision’s direct mould process starts with the group’s engineers selecting a material combination for the tool surface and support structure that will provide the optimum match between the coefficient of thermal expansion (CTE) of the mould and the composite part to be processed.  The CNC machined composite face sheet is supported by a stress-relieved metallic or composite backing structure before final post curing and machining is completed. The principal benefit of this novel approach, aside from removing the need for costly and time-consuming plug production, is the production accuracy delivered by the closely matched CTE of the mould tool and the finished composite part.

The autoclaved composite tool surface is not only extremely dimensionally stable up to processing temperatures of 180˚C, but it can also be configured with additional metallic inserts or fixtures if required.  

Produced in an EN 9100:2018 controlled production environment, and with CMM checks before and after machining, the new direct composite tools have dimensional tolerances of +/-0.2mm.  The available tooling dimensional envelope is currently defined by Decision’s 2200mm x 6000mm autoclave.

“With our new direct tooling technology, we are able to combine the highest technical standards in dimensional accuracy and thermal stability with extremely short lead times.  Decision and Carboman Groups’ combined mission has always been to develop the construction methods for tomorrow’s composite structures, and we believe that this tooling solution will allow our customers to accelerate the implementation of the next generation of high-performance carbon fibre aerostructures and components” Grégoire Metz, Managing Director, Decision SA.

Kornit Digital announced United Kingdom-based Tayprint has implemented the Kornit Avalanche HD6 system for efficient, versatile direct-to-garment (DTG) apparel production on demand. This technology effectively replaces the use of screen printing within their operation, reducing their cost per print while making short runs profitable, eliminating inventory and resource waste, speeding production, and ensuring nearly unlimited design capabilities, applied to a broad array of materials, using a single eco-friendly ink set.

While Tayprint predominantly serves as a provider of large-format digital printing, delivering approximately 500,000 square metres of imprinted product annually, they had established a screen-printing operation, as well, generating roughly £200,000 in t-shirt sales per year. While this provided a strong profit channel, screens offered limited growth potential, as order volumes were shrinking, customers demanded quick turnaround, graphic capabilities were limited, and setting up was a drain on both labour and materials. Each of these drawbacks are addressed by Kornit’s on-demand digital production technology, which enables suppliers to imprint apparel in any quantity, using a single-step process, completing the process in mere minutes.

Tonello and RUDOLF HUB1922 join forces and unveil laser effects. The results: A much simplified, flexible and efficient process - based on latest technological advancements and highly conscious chemistry - that is finally able to replace questionable practices such as potassium permanganate spray.

THE Laser, the absolute Laser
The range that is the new benchmark for the entire sector. New software and a totally reinvented process that return higher precision, speed, flexibility and repeatability. Four models for a specific crafting and avant-garde functions like 360° marking technology, BOP for automatic drawing positioning and the new software CREA make THE Laser suitable and unique for advanced applications.

Laser Smoother (RUCO-SPECIAL LSM)
All-in-one formulation - very easy to pre-apply to garments before laser burning - that translates into a very natural image that is similar to what is created by hand. RUCO SPECIAL LSM amplifies the laser action, completely removes the grey/brow patina produced by the burning of cotton and last but not least, creates a micro-unevenness that simulates manual scraping and celebrates the fabric construction.

The combination of THE Laser and RUCO-SPECIAL LSM (ideally applied through CORE system) is a process that nothing adds to the usual way of working. It is a radical paradigm shift that takes the product directly to a dimension of real, highly sustainable craftsmanship:

• Remarkable enhancement of the fabric’s characteristics;
• Overall effect much more natural and similar to manual scraping;
• A better and more efficient way of working.

Hexcel announces its latest HexPly® XF surface technology that reduces shell manufacturing time within the wind blade surface finishing process. HexPly XF increases overall blade manufacturing efficiency by reducing time in the mold by up to two hours and by banishing surface defects that require rework before painting.

Hexcel’s HexPly XF surface technology has been formulated to address the limitations of current blade shell surfacing techniques whereby pinholes and other surface defects have to be repaired by hand to achieve the perfectly smooth surface required for painting.

HexPly XF surface technology introduces a new material format as the surface finishing layer, eliminating the need for a traditional in-mold gel coating process. HexPly® XF for infused rotor blades, is a lightweight non-woven semi-preg construction, comprising an epoxy resin matrix, that co-cures with standard epoxy infusion systems. The product has a successful track record in prepreg blades and has now been adapted for infusion processes.

Easy to handle and supplied in a ready to use roll form, HexPly XF can be quickly applied by hand or with semi-automated layup equipment. It features one self-adhesive, surface finishing side - indicated by a removable protective foil. This side of the prepreg is placed against a release agent treated mold surface. Once the material has been positioned, the lay-up of the blade shell structure can start immediately, and the laminate can be infused. After curing, the blade is de-molded with the manufacturer benefitting from a pinhole-free surface that needs minimal preparation before painting.

HexPly XF material is less than half the weight of a typical gel coat per square meter, reducing the overall weight of the blade. Additionally, the consistent areal weight and thickness of the prepreg film provide a completely uniform surface coating, ensuring blade weight distribution and balance are maintained, which is critical as rotor diameters continue to increase. With no need to handle or mix liquid chemicals as in the gel coat process, HexPly® XF also improves the health and safety working conditions on the shop floor.

The material has a shelf life of six weeks at ambient temperature, which also minimizes cold storage requirements and helps to reduce scrap.

Intelligently designed clothes made with the latest manufacturing technology are the results of the partnership between on of the leading denim innovators ISKO and the Italian brand HIGH. A project, part of the SS2021 HIGH collection, is the start of collaboration in the pursuit of sustainable fashion.

Aimed at bringing a positive change both for the planet and its people, the project presents two pieces – jacket and pants – which embody HIGH’s approach to creativity and production: a wellbalanced mix of specialists’ expertise and a tireless investigation on the latest and most responsible fabric technologies. HIGH identified the R-TWO™ program as the right fabric ingredient, ideal to level up sustainability in its looks.

Relying on a blend of reused and recycled materials, this revolutionary platform works by embedding material circularity into the production process, designing waste out of the system and minimizing impact at scale. With fully traced reused cotton coming from ISKO’s production loss, which is prevented from becoming waste by adding it back into the spinning process, and an efficient use of polyester materials which are spun into newly recycled fibers, the program can provide certified to Textile Exchange environmental credentials. According to the percentage of material contained, these can be either the Content Claim Standard, Global Recycled Standard, Organic Content Standard or Recycled Claim Standard, ensuring better use of raw materials and resource efficiency while providing advanced concepts that don’t compromise on their look and performance.

Additionally, to meet HIGH’s performance needs, ISKO has brought to the table one of its most popular technologies, of course in its R-TWO™ version: Jeggings™, super-stretch denim technology. Soft and lightweight as leggings, it provides comfort with the look of authentic denim and provides the perfect, responsible solution to usher the partnership.

Reinach, Switzerland, and Westlake, Ohio, 2 February 2021 - Archroma, a global leader in specialty chemicals towards sustainable solutions, today announced a strategic partnership with technology innovator CleanKore, aiming to advance sustainable dyeing processes throughout the denim supply chain.

The agreement will allow Archroma and CleanKore to promote the benefits of each other’s technologies. This includes Archroma’s robust catalog of dyes and specialty chemicals along with CleanKore’s patented process of dyeing yarns at the denim mill that completely eliminates the need for potassium permanganate (PP) spray and laser booster to achieve the bright white abrasion effect in the garment finishing process. The result is a large and circular bright white core with a small ring of indigo dye. The technology does not just eliminate the chemicals associated in the PP spray and laser process, which is much safer for denim workers, it also allows to save significant amounts of water and energy throughout the manufacturing process from fabric to garmenting.

CleanKore initially looked at eliminating potassium permanganate due to its being classified as hazardous if inhaled or ingested, or in case of contact with the skin or the eye. It is also considered very toxic to aquatic life. No new equipment or capital expenses are needed to implement the CleanKore technology, which works on all denim fabric, including dark indigo, sulfur top/bottom and sulfur black.

This is where Archroma comes into the picture. Its global technical team of denim coloration specialists will provide support to denim mills seeking to implement the CleanKore technology and develop the desired looks and effects - with the right colors and chemical systems for their production set-up.

CleanKore estimates that the technology allows to save up to 15 liters of water per garment, or the equivalent to the drinking needs of 5 people per day, and up to 0.51 kWh of energy per garment, or the equivalent of five 100-watt light bulbs on for 1 hour. The CleanKore technology also leads to a 10% to 20% increase in production throughput, as a result of a faster garment wash-down and the elimination of PP spray.

For CleanKore CEO Darryl Costin Jr., the announcement comes at an ideal time for CleanKore: "We have successfully proven the technology with mill partners such as Arvind and other denim mills in Pakistan, Bangladesh, China, Vietnam, Thailand and the United States. The response from the industry has been overwhelmingly positive. Having a partner in Archroma, one that is highly respected for their innovation and emphasis on sustainability throughout the industry, will allow us to take CleanKore to the next level.”

Umberto Devita, Global Indigo Manager at the Archroma Global Competence Center for Denim & Casualwear, adds: "CleanKore is perfectly aligned with the 3 pillars of 'The Archroma Way to a Sustainable World: Safe, efficient, enhanced'. 'Safe' through the elimination of a potentially harmful substance and the protection of the denim workers, 'Efficient' through the reduction of resource consumption, improved productivity and cost-effective profile. And 'Enhanced' through the gorgeous colors and effects allowed with Archroma's innovations and systems, in particular our aniline-free* Denisol® Pure Indigo and Diresul® sulfur dyes. We look forward to help promoting an innovation that will help with many of the challenges facing our denim customers throughout the world. Because it’s our nature."

• ISKO Vital™+ Premium community face cover receives the NEN certification in the Netherlands.

The responsible face cover brand is the first to be awarded the Dutch standard, recently established by The Royal Netherlands Standardization Institute. The mark of conformity was issued on January 19, when ISKO Vital+ completed the certification process.

Supported by parent company ISKO’s 100-years of experience and know-how in the textile industry, ISKO Vital+’s range of Premium face covers has exceeded the requirements set out by NEN for community face covers. The recently established Dutch standard, NEN-spec 1- 2 requires manufacturers to pass rigorous testing for bacterial filtration efficiency, breathing resistance, fit and ease of use and sustainability.
With a bacterial filtration efficiency (BFE) of ≥95% that exceeds the NEN’s minimum requirement of ≥70%, the ISKO Vital+ Premium face cover is a patented 4-fold design made from ISKO Vital™ fabric, a groundbreaking textile solution created by ISKO’s in-house research and development experts. It is fluid repellent and very easy to breathe through thanks to a single layer of organic cotton which is dermatologically tested, OEKO-TEX Standard 100 certified and gentle on the skin, providing a superior level of comfort as assessed by an independent panel.

Available in different sizes and colors, the Premium face covers surpass the minimum NEN requirement for breathing resistance of <70 Pa/cm2 too, with a respiratory resistance lower than 40 Pa/cm2 – making the face covers very comfortable to wear. In addition, they are much more sustainable than disposable masks as they can be reused and hand or machine-washed up to 15 times without loss of quality. “Current circumstances are expected to last in the foreseeable future, so it is extremely important to wear proper community face covers”, explained Edgar van der Linden, ISKO Vital™ Medical Business Lead. “Thanks to the mark of conformity, it is now clear that face cover must have the highest possible filtration efficiency and must also be comfortable, expressed in the lowest possible breathing resistance. Environmental aspects are also addressed. As a supplier of washable face covers made from one innovative layer of organic cotton we consider that very important. A good community face cover offers a combination of high filtration efficiency, comfort, ease of use and minimizes the burden on the environment”.
