From the Sector

Hexcel is collaborating with NaCa Systems, a Tier 1 supplier of natural fiber composite automotive interior parts, on the development of a lightweight carbon fiber prepreg and wood fiber composite sportscar seat back using a rapid press molding process. This innovation validates a short cycle time production process for CFRP and wood fiber composite parts and offers a host of benefits to automotive manufacturers.

Hexcel supplies NaCa Systems with an optimized version of its HexPly® M77CS epoxy prepreg material. HexPly® M77CS is a fast curing hotmelt, thermosetting epoxy matrix, specifically designed for prepreg applications for which short cure cycles and clear surfaces with perfect aesthetics are required.

The lightweight seat back demonstrates a 40% weight saving compared to a typical injection molded plastic component whilst also featuring a significantly improved CO2 footprint vs a full carbon part. The prepreg and wood fiber structure doesn’t produce sharp edged pieces when damaged. In addition, wood fiber composites also increase sound absorption, contributing to improved NVH damping within the vehicle interior.

The NaCa Systems seat back will be on display on the Hexcel stand at JEC World 2020.

The origins of both Industry 4.0 and an awareness of the need for more sustainable manufacturing methods can arguably be traced back to the year 1971.

It was in 1971 that the first microprocessor was introduced by Intel, and also that the first and perhaps now most well-known environmental campaigner, Greenpeace, was founded.

As such, a direct line can be charted from that year to today’s automated textile manufacturing machinery concepts, as well as the drive to develop more increasingly resource-efficient processes.

All of the recent innovations which have been introduced to the market by A. Monforts Textilmaschinen GmbH & Co. KG, for example, are being powered by the possibilities of Industry 4.0 and developed in response to the market demand for more sustainable production.

They include the new ‘digital twinning’ capability introduced in 2019 for all Monforts machines, with advanced sensor technologies which make it possible to access comprehensive technical machine data from any location using the company’s Smart Support and Smart Check apps. In addition, the digital twin system provides information on individual wear parts, such as, for example, converters or gears.

These latest developments have been very favourably received by Monforts customers, especially in Europe.

50th anniversary
The very first Heimtextil – the leading trade fair for the home textiles market – was also held in Frankfurt in January 1971 and Monforts customers Bierbaum Group and Konrad Hornschuch AG are amongst the German companies who were there from the very start and have attended every annual show since.

Bierbaum Group, based in Borken, is the company behind the well-known Irisette bedding brand and is celebrating its own 125th anniversary in 2020. It has also introduced products bearing the German government’s new Grüner Knopf textile seal of approval for sustainable production.

As a specialist in synthetic leathers for home surfaces, as well as vehicle interiors, Konrad Hornschuch AG, of Weissbach, has been a member of the €44 billion automotive giant Continental AG since 2016.

Representatives from both companies received memorial trophies at a special presentation held on January 7th during the 50th anniversary Heimtextil show.

The home textiles market remains very strong in Germany, with sales amounting to some €9.6 billion in 2019, according to analyst IFH Cologne.

Global growth
The first Heimtextil in 1971 was a significant success, attracting 679 exhibitors from 26 countries.

This year’s show, however, attracted a total of 2,952 exhibitors from 66 countries, reflecting not only the growth of the home textiles industry, but also the globalisation which has taken place over the last half century.

Monforts now has customers for its advanced finishing technologies around the world, with home textile customers from India and Pakistan being particularly well represented at Heimtextil 2020.

Among stand outs from Indian companies at this year’s show was the 2020 collection of Welspun India’s famous Christy England brand, inspired by botanical studies of the gardens of British stately homes. Welspun towels meanwhile benefit from the company’s HygroCotton hollow core yarn technology, produced by a proprietary spinning method which ensures they become softer, fluffier and more absorbent after every wash.

An equally ground-breaking new technology is being introduced by Trident Group, which is one of India’s largest vertically-integrated home textiles manufacturers and two years ago installed five complete Monforts finishing ranges for its new linen department.

Trident’s patented Air Rich yarns feature pores throughout their cross sections for high breathability and absorbency, as well as rapid drying.

Monforts home textile customers from Pakistan stressed the resource efficiency of their processes and products as a result of investments in advanced technology, and during the show the ‘Sustainable Pakistan’ initiative was announced.

Supported by GIZ, the German Society for International Cooperation, the initiative aims to reshape global perceptions of Pakistan’s manufacturers and their innovations. So far, twenty producers have been carefully chosen to be presented on this global platform and will help rebrand Pakistan’s textile industry at the Heimtextil exhibitions going forward.

Heimtextil’s organiser Messe Frankfurt also announced its own new alliance with the United Nations Office for Partnerships, in order to support the UN’s Sustainable Development Goals.

Constancy
Many things have changed since 1971 and home interiors are certainly no longer predominantly orange and brown – and perhaps unlikely to ever become so again.

It’s clear, however, that there has been a constancy in the push to consistently improve textile technologies, processes and products that may have originated in Europe, but have subsequently spread around the world.

And the significance of both microprocessors and sustainability in 2020 could only have been guessed at back in 1971.

 

COBRA International is collaborating with HG Robotics, a leading drone manufacturer that specializes in unmanned aerial vehicles (UAVs) for the agricultural market, on a composite fuselage cover for the cutting-edge Tiger Drones.

Undertaking a full range of services with HG Robotics and having been involved from the outset: from the design and engineering through to the prototyping of the composite drone fuselage cover, COBRA has now delivered nearly 100 sets and will produce approximately 500 units throughout 2019.

The multi-rotor Tiger Drones typically carry spraying equipment and can also carry high definition cameras that provide a wide range of field information. Farmers can measure land profiles, identify any problem plants or areas and manage their cultivation in the most efficient way. The 420 mm square shaped fuselage cover protects the drone’s electronic controls and forms an aerodynamic fairing between the central fuselage and the craft’s 4 rotor arms.
 
The COBRA Design and Development team selected a composite laminate of glass fibre reinforcements for the cover – which don’t interfere with GPS signals used by the drone - and combined these with epoxy laminating resins in a hand laminated, vacuum bag consolidated production process.

COBRA also designed all of the mould tools for the project. The 2-piece aluminium mould was produced by one of COBRA’s long-term tooling partners. This metallic tooling provides an excellent surface finish to the part with absolutely minimal trimming and finishing required.   Moulded parts can go swiftly through a painting and clear coating process before final inspection and delivery to the client.

Danu Chotikapanich, CEO of COBRA International comments: “Our collaboration with HG Robotics is going well, and we are hoping to collaborate further with them on other multi-rotor and fixed wing VTOL (vertical take-off and landing) drone models in the future. These are COBRA’s first parts for the agricultural industry, and they provide an exciting vision as to just a few of the possibilities for lightweight composites in this area and also in the wider commercial UAV market as a whole.”

With the announcement of the eligible vehicle models, the World Car Awards 2020 kickedoff today at the IAA Motor Show in Frankfurt, Germany. This year again, the majority of contenders is equipped with lightweight components for acoustic and thermal management from Autoneum. The world’s leading automobile industry awards will be presented at the New York Motor Show in the spring of 2020.

A total of 46 new vehicle models have passed the initial screening and are now contenders for trophies in the categories “World Car of the Year”, “World Luxury Car”, “World Performance Car”, “World Urban Car” and “World Car Design of the Year”, including five new fully-electric models alone. Whether it’s a lightweight underbody, a noise-absorbing carpet system or a heat-reducing engine encapsulation – most of the eligible vehicles benefit from Autoneum’s innovation leadership in thermal and acoustic management. Autoneum’s expertise extends to new forms of mobility such as electric vehicles: Also thanks to numerous Autoneum components, Jaguar’s fully-electric SUV “I-PACE” impressed the jurors for the World Car Awards 2019, which was the first model ever to be named “World Car of the Year”, “World Car Design of the Year” and “World Green Car” at the same time.

On the occasion of today’s eligibility announcement, Autoneum CEO Martin Hirzel said: “Once again, the contenders are testimony to our innovation leadership. The World Car Awards also confirm our forward-looking approach: Nominated e-models feature Autoneum components as well. Welcoming our industry’s transformation early on, we today supply environmentally sustainable, lightweight components for most electric models available worldwide.”

Gerry Malloy, President of the World Car Awards Association, added: “As a market leader, Autoneum is the ideal partner for us. Our shared commitment to innovation was a decisive factor in forming a partnership back in 2014. Nowadays, this is a crucial aspect for manufacturers and suppliers who wish to remain successful in times of industrial and technological change.”

The World Car Awards, which have been presented annually since 2004, are the world’s leading nd most widely recognized automotive industry awards. A jury comprising of more than 80 international automotive journalists selects winners in five categories. The winners of the 2020 World Car Awards will be announced in April next year at the New York Motor Show.

With Alpha-Liner, Autoneum launches its first-ever textile wheelhouse outer liner that not only reduces tire noise substantially, but also convinces with low weight. This newest lightweight component ensures a quiet driving experience and also helps vehicle manufacturers meet current and future noise and emission limits. Alpha-Liner premieres at the “Automotive Acoustics Conference” which takes place in Zurich,
Switzerland, on July 9 and 10.

Alpha-Liner is the latest innovation from Autoneum – a multifunctional wheelhouse outer liner that reduces tire noise with high efficiency and thus makes the vehicle quieter and lighter. Alpha-Liner is based on Autoneum’s newly developed technology, with which noise absorption can be adapted to the specific requirements of the vehicle model for the first time. To achieve this effect, a thin coated surface is applied on the tire side. The porosity of the coating can then be controlled according to the necessary absorption properties, the bottom part of the wheelhouse outer liner requires stronger noise treatment, which maximizes acoustic absorption.

STAMFORD, Conn. – At this year's Paris Airshow [Le Bourget, June 17-23] Hexcel will promote a range of carbon fibers and composite materials used to manufacture high-performance weight-saving structures in civil aircraft, engines, helicopters, and space applications.

Visitors to the Hexcel stand will see an Integrated Wing Panel demonstrator and an I-beam, both made with HiTape® carbon fiber reinforcements. HiTape® dry carbon reinforcements were developed for the automated lay-up of preforms and to complement a new generation of HiFlow™ resin systems, producing high-quality aerospace structures using the resin infusion process. The reinforcements incorporate a toughening veil to enhance mechanical properties and meet the structural requirements for aerospace parts. The I-Beam was manufactured using C-RTM (Compression Resin Transfer Molding) and was injected with Hexcel’s RTM6 resin in a process taking less than five minutes.

Hexcel honeycomb saves weight and enhances stiffness in composite structures, and the company provides a range of engineered core solutions that enable highly contoured parts with precision profiling to be produced to exact customer specifications. A sample part made from aluminum FlexCore® that is CNC machined on both sides and formed and stabilized with both peel ply and flyaway layers of stabilization will be on display.

Another honeycomb innovation is Hexcel’s Acousti-Cap® broadband noise-reducing honeycomb that significantly improves acoustic absorption in aircraft engine nacelles. The acoustic treatment may be positioned at a consistent depth and resistance within the core or can be placed in a pattern of varying depths and/or resistances (Multi-Degrees of Freedom and 3 Degrees Of Freedom), offering an acoustic liner that is precisely tuned to the engine operating conditions. These technologies have been tested at NASA on a full engine test rig and meet all 16 design conditions without trade-offs.
Another Hexcel technology to benefit aircraft engines is HexShield™ honeycomb which provides high-temperature resistance in nacelles. By inserting a thermally resistant material into honeycomb cells, Hexcel provides a core product with unique heat-shielding capabilities that allows for the potential reuse of material after a fire.

With 50 years of experience behind its comprehensive range of high-strength, high-strain PAN-based carbon fibers, Hexcel continues to innovate and is introducing two new fibers to its portfolio. HexTow® HM50 combines high modulus and high tensile strength, making it ideal for commercial and defense aircraft and engines. HexTow® 85 was developed specifically to replace rayon-based carbon fiber for ablative applications.

Another area of expertise that uses HexTow® carbon fiber is additive manufacturing, where Hexcel uses PEKK ultrahigh performance polymers and HexAM™ technology to manufacture carbon reinforced 3D printed parts. This innovative process provides a weight-saving solution for intricate parts in highly demanding aerospace, satellite and defense applications. HexPEKK™ structures offer significant weight, cost and time-to-market reductions, replacing traditional cast or machined metallic parts with a new technology.

Later this year Hexcel will open a joint research and development laboratory in Les Avenières (Isère), France with Arkema to develop carbon fiber-reinforced thermoplastic prepreg tapes for aerospace, space and defense applications. A spool of thermoplastic prepreg tape will be on display on Hexcel’s stand to showcase this cost-effective technology that enables lightweight parts to be produced in faster production cycles for future generations of aircraft.

Hexcel’s stand is located next to Hexcel’s official distributor for aerospace products, Groupe Gazechim Composites. In 2018, Hexcel and Gazechim formed a joint venture, HexCut Services, to provide aerospace and defense customers with customized kitting services that include Hexcel’s innovative carbon fiber prepreg, fabrics and adhesives. Pre-cut kits save customers time and investment, reduce inventory and minimize material losses through scrap reduction.

For the cooperation with Lidl within the project “Biodegradable textiles with prints” the CHT Group developed innovative recyclable textile print products.

These Lidl textiles are produced with CHT print pastes and pigments and were certificated by the internationally active consulting institute EPEA GmbH - Part of Drees & Sommer according to the Cradle to Cradle Certified™ Gold Standard. With this pilot project the companies demonstrate their sense of responsibility for people and the environment as well as their commitment in the field of circular economy.

According to the Cradle to Cradle approach, shortly C2C, products shall merge into a biological or technical cycle after the end of their life cycle. This re-use helps prevent waste and save raw materials. The impact on the environment and health of all of the ingredients of C2C textiles is already tested in the design stage and during manufacturing. C2C experts additionally ensure a gapless control of the manufacturing processes. They check the chemicals in use, make sure that the water is kept clean and that renewable energies are used. Since this control affects the complete textile supply chain, it guarantees absolute transparency.

The CHT Group can now offer high quality and sustainable substitutes for common textile print pastes with its first biodegradable print pastes and pigments.

Techtextil 2019: Schoeller launches its new finishing technology called NanoSphere® Plus. The special effect of this new development is its protection against fingerprints and greasy stains. Furthermore, even after being absorbed by the fabric stains are quickly and easily wiped away without washing.

Every human being leaves its marks. In particular, on daily-use items that are picked up or touched often. Especially on textile surfaces, hand and fingerprints in combination with dirt and dust particles leave an unpleasant, greasy dirt film, which is very difficult to clean.

NanoSphere® Plus, developed by Schoeller Technologies AG, the business unit for technologies at Schoeller Textil AG, works on the basis of a functional chain. Textiles are equipped with a matrix finish to reduce the capillary effect in the textile’s fibers. Especially unpleasant sebum residues and dirt that are often released by finger and handprints are less absorbed by the fabric and can be easily wiped away.

Beside the excellent protection against finger and handprints, textiles with NanoSphere® Plus are additionally water and oil repellent, abrasion resistant and extremely durable. The finishing technology rarely affects the look or feel of the fabric.

Non-washable textiles that are often touched by hands or fingers, or fabrics that are in direct contact with the skin benefit most from this new technology. Therefore, NanoSphere® Plus is ideal for woven fabrics and synthetic leather or synthetic suede for bags, covers of electronical devices, head phones, loud speakers or other items in the field of interior equipment.

• Hexcel’s Composite Innovations For Aerospace, Automotive, Energy And Marine Applications At JEC World 2019 Hall 5 - Stand J41

STAMFORD, Conn. – At this year’s JEC World taking place in Paris on March 12-14, Hexcel will promote a wide range of composite innovations for customer applications in aerospace, automotive, energy and marine markets.

Aerospace Innovations

Hexcel’s HiTape® and HiMax™ dry carbon reinforcements were developed to complement a new generation of HiFlow™ resin systems, producing high quality aerospace structures using the resin infusion process. HiTape® was developed for the automated lay-up of preforms and HiMax™ is a range of optimized non-crimp fabrics (NCF). Both products incorporate a toughening veil to enhance mechanical properties, meeting the structural requirements for aerospace parts.

Visitors to JEC will see an Integrated Wing Panel demonstrator and an I-beam, both made with HiTape® reinforcements, and an Opticoms rib made with HiMax™ NCF. The Opticoms rib and I Beam were both manufactured using C-RTM (Compression Resin Transfer Molding). They were injected with Hexcel’s RTM6 resin in a process taking less than 5 minutes. The total manufacturing cycle for both parts was just 4.5 hours.

Also among the Aerospace exhibits, Hexcel will display a composite petal for a satellite antenna, manufactured by Thales Alenia Space Italia. The petal is part of a set of 24 deployable structural elements that form the large area reflector assembly used on board Low Earth Orbit (LEO) observation satellites. Thales Alenia Space Italia selected Hexcel’s HexPly® M18 prepreg for this application, acknowledging the superior mechanical and outgassing properties provided.

Another Hexcel prepreg application on show is a “zero” frame, manufactured by Aerofonctions for the engine area of Daher’s TBM 910/930 single-engine turboprop aircraft. Hexcel’s HexPly® M56 prepreg was selected by Daher for the “zero” frame – a product developed for Out of Autoclave applications that provides the same high quality and performance as autoclave-cured prepregs, from a simple vacuum bag cure in an oven.

With 50 years of experience behind its comprehensive range of high-strength, high-strain PAN-based carbon fibers, Hexcel continues to innovate, and is introducing two new fibers to its portfolio. HexTow® HM50 combines high modulus and high tensile strength, making it ideal for commercial and defense aircraft and engines. HexTow® 85 was developed specifically to replace rayon-based carbon fiber for ablative applications.

HexTow® carbon fiber holds the most qualified carbon fiber positions on aerospace programs in the industry and is the best unsized fiber available on the market. It provides excellent bonding interfacial properties with thermoplastic matrices and is the best-performing fiber for 3D printing applications.

Additive manufacturing is another area of expertise for Hexcel, using PEKK ultra-high performance polymers and HexAM™ technology to manufacture carbon-reinforced 3D printed parts. This
innovative process provides a weight-saving solution for intricate parts in highly demanding aerospace, satellite and defense applications. HexPEKK™ structures offer significant weight, cost and time-to-market reductions, replacing traditional cast or machined metallic parts with a new technology.

Hexcel is well known for its range of weight-saving, stiffness-enhancing honeycombs and the company adds value by providing a range of engineered core solutions to customers from facilities in the USA, Belgium and the newly opened Casablanca plant in Morocco. Hexcel’s engineered core capabilities enable highly contoured parts with precision profiling to be produced to exacting customer specifications. An example of such a part will be on display at JEC. Made from Aluminum FlexCore®, the part is CNC machined on both sides, and formed and stabilized with both peel ply and flyaway layers of stabilization. Aircraft engines benefit from a number of Hexcel core technologies including HexShield™ honeycomb that provides high temperature resistance in aircraft engine nacelles. By inserting a thermally resistant material into honeycomb cells, Hexcel provides a core product with unique heat-shielding capabilities that allows for the potential re-use of material after a fire event.

Hexcel’s Acousti-Cap® broadband noise-reducing honeycomb significantly improves acoustic absorption in aircraft engine nacelles. The acoustic treatment may be positioned at a consistent depth and resistance within the core, or can be placed in a pattern of varying depths and/or resistances (Multi-Degrees of Freedom and 3 Degrees Of Freedom), offering an acoustic liner that is precisely tuned to the engine operating conditions. These technologies have been tested at NASA on a full engine test rig and meet all 16 design conditions without trade-offs.

HexBond™ – the new name in Adhesives

Hexcel’s range of high performance adhesives has expanded considerably following the company’s acquisition of Structil. The company has now decided to unite the range by marketing all of its adhesive products using HexBond™ branding. The comprehensive range of HexBond™ structural film adhesives, foaming adhesive films, paste adhesives, liquid shims, epoxy fillets and Chromium free liquid primers is suitable for a wide range of applications in combination with Hexcel’s prepreg and honeycomb products.

Automotive Innovations

Hexcel’s carbon prepreg patch technology provides an innovative way of locally stiffening and reinforcing metal parts, providing noise and vibration management functionality. HexPly® prepreg patches consist of unidirectional carbon fiber impregnated with a fast curing epoxy matrix that has self-adhesive properties, enabling it to bond to metal in a highly efficient one-step process. These key technology properties are demonstrated in an 18.5kg aluminum subframe (that is 50% lighter than steel equivalents), which was reinforced with 500 grams of HexPly® prepreg and tested by Saint Jean Industries. The part demonstrates a significant reduction in noise, vibration and harshness (NVH). Other benefits include lower production costs, energy savings, increased driver comfort, production flexibility and part count reduction. With this technology Hexcel is a finalist in the JEC Innovation Awards 2019 in the Automotive Applications category.

HexPly® prepreg patch technology was also applied to a hybrid side sill demonstrator developed with Volkswagen and Dresden University to address future crash test requirements, specifically for electric cars. Combining fiber-reinforced plastic (FRP) with metal, the hybrid construction allows for optimum performance including weight savings, enhanced safety, increased energy absorption, battery protection in a crash situation and production flexibility.

Hexcel will also display a lightweight CFRP transmission crossmember produced from Hexcel’s high performance HexMC®-i 2000 molding compound. The transmission crossmember was developed in partnership with the Institute of Polymer Product Engineering (at Linz University), Engel and Alpex. As the part connects the chassis together and supports transmission it has to be stiff and strong, resisting fatigue and corrosion. Hexcel’s HexMC®-i 2000 was selected as the best-performing molding compound on the market, curing in as little as two minutes to produce lightweight, strong and stiff parts.
To produce the transmission crossmember HexMC®-i 2000 preforms are laid up in Alpex molds and compression-molded in a v-duo press that was tailored for the application by Engel. Ribs, aluminum inserts and other functions can be molded into the part using the single-stage process, reducing component-count. Any offcuts from the preforms can be interleaved between the plies of material to provide additional reinforcement in key areas - meaning that the process generates no waste.

Other Automotive promotions on Hexcel’s stand at JEC World include a composite leaf spring manufactured by ZF using HexPly® M901 prepreg. In contrast to steel leaf springs, composite versions offer many advantages including weight savings of up to 70%, high corrosion resistance, optimized system integration and superior performance. HexPly® M901 prepreg reduces the cure cycle to below 15 minutes and provides 15% higher mechanical performance, with enhanced fatigue properties. It also operates at high temperatures, providing a Tg of up to 200°C following a post cure.

Marine Innovations

Hexcel has a comprehensive range of products aimed at racing yacht and luxury boat builders that include America’s Cup, IMOCA class and DNV GL-approved prepregs, woven reinforcements and multiaxial fabrics for hull and deck structures, masts and appendages.

At JEC World Hexcel will display an IMOCA yacht mast manufactured by Lorima using HexPly® high modulus and high strength carbon fiber prepreg from Hexcel Vert-Le-Petit. Lorima is the exclusive official supplier of masts for IMOCA 60 class racing boats.

Hexcel’s HexTow® IM8 carbon fiber has been selected as the highest performing industrial carbon fiber on the market and will be used by spar and rigging manufacturer Future Fibres to manufacture their AEROrazr solid carbon rigging for all the teams in the 36th America’s Cup.

Hexcel’s HiMax™ DPA (Dot Pattern Adhesive) reinforcements are non-crimp fabrics supplied pre-tacked, allowing multiple fabrics to be laid-up more easily in preparation for resin infusion. Providing an optimal, consistent level of adhesion, they allow a faster and more consistent resin flow, as well as eliminating the use of spray adhesive for a healthier working environment and lower risk of contamination. Simply unrolled and applied to the mold or core layer before the introduction of resin, HiMax™ DPA fabrics are widely used in boat building, where lay-up times can be reduced by up to 50%.

Wind Energy Innovations

Hexcel has developed a range of HexPly® surface finishing prepregs and semi-pregs for wind turbine blades and marine applications. Providing a tough, durable and ready-to-paint surface without using in-mold coats, these products shorten the manufacturing cycle and reduce material costs. HexPly® XF2(P) prepreg is optimized for wind blades and has a ready-to-paint surface, straight from the mold, saving at least 2 hours of takt time.

Polyspeed® pultruded carbon laminates were developed for load-carrying elements in a blade structure and are manufactured with a polyurethane matrix that provides outstanding mechanical performance in terms of stiffness and durability. The blade manufacturing process is optimized, with increased throughput. The pultruded laminates are supplied in coils as continuous cross section profiles.
HiMax™ non-crimp fabrics using E-glass, high modulus glass and carbon fibers are also available in a wide range of unidirectional, biaxial and triaxial constructions. HiMax™ fabrics have applications throughout the turbine, from the stitched carbon fiber UDs used in the main structural elements, to glass fabrics and hybrids for blade shells and nacelles. There are also specialist applications such as lightweight fabrics for heated leading edge de-icing zones.

Archroma, a global leader in color and specialty chemicals towards sustainable solutions, today announced that Thailand-based Absolute Denim will be the first denim manufacturer to switch 100% of its production to aniline-free* indigo dyeing.

Absolute Denim is a Thailand-based denim manufacturer producing high quality denim with a focus on eco-friendlier materials and processes. The company can produce up to 2 million meters of denim per month (that's approximately 1.5 million pairs of jeans!), for customers that include some of the biggest brands and retailers in the world.

Archroma’s Denisol® Pure Indigo 30 liquid dye was first launched in May 2018 as a non-toxic way to produce the traditional, iconic indigo blue that consumers associate with denim and jeans.

During production, some of the aniline stays locked into the indigo pigment and is difficult to wash off the fabric. The remainder of the aniline impurity, approximately 300 metric tons annually, is discharged during dyeing. This can be an issue as aniline is toxic to aquatic life. In addition, exposure levels to factory workers can be high. As a result of its toxicity (more hazardous than alkylphenols) it is now starting to feature on the restricted substance lists (RSL) of some major clothing brands and retailers.

The new Denisol® Pure Indigo 30 liq was therefore developed as an aniline-free* indigo solution for designers, manufacturers and brand owners who long for authentic indigo inspiration.

Archroma tested Denisol® Pure Indigo at Absolute Denim mill in Thailand. Archroma wanted to be sure that the new indigo dye would perform exactly the same as conventional indigo.

James Carnahan, Head of Sustainability at Archroma, comments: “At Archroma we continuously challenge the status quo in the deep belief that we can make our industry sustainable - but we cannot do it alone. Without forward-thinking manufacturers such as Absolute Denim to consciously adopt these eco-advanced innovations in their daily production, like our aniline-free* Denisol® Pure Indigo, we will not be able to move this industry forward on our resource-constrained world we live in. As consumers are increasingly aware of, and concerned about, climate change and ecological threats, this is not only the right thing to do - it is also good for business.”

“Deep down inside most of us want the world to be a better place for our loved ones and for future generations,” insists Vichai Phromvanich, Board Member, Absolute Denim, “starting with how we live, what we eat, what we wear, still trying to be cool, fashionable, still trying to be environmentally conscious. Archroma’s aniline free indigo project is therefore something we as a new generation manufacturer have supported from the beginning, by opening our doors for tests in the project phase, and now by sending out our articles to many of our customers. For us, after all, a nice pair of jeans looks even nicer without aniline!”
