From the Sector

Cobra International, Chonburi, Thailand: COBRA International, one of the world’s largest OEM manufacturers of composite goods for Water Sports, Automotive, Marine and Civil Engineering, is pleased to confirm the shipment of its first 36 composite canoes to ARE Tahiti.

COBRA has collaborated with leading outrigger canoe brand ARE Tahiti to mass produce its new OC-1 canoe, ‘Mana’. Designed by former professional windsurfer Baptiste Gossein  (JP Australia and Neil Pryde), ‘Mana’ features a closed deck on which the paddler sits on top of the hull. Available in two models; a hybrid version weighing 12kg, using an 80:20 mix of E-glass and carbon fibre reinforcement fabrics, and the PRO model – a weight optimized, ultra-light, full carbon version that weighs as little as 9kg.   

“We required the best in composite construction for both models, a stunning final finish and a build rate that could keep up with our growing order book”, comments Baptiste Gossein.

As with all of COBRA’s watersports’ projects, a perfect master model formed the basis of the mass production tooling and two sets of composite hull tooling were taken from the master plug allowing a build rate of up to 50 OC-1 canoes per month.

For the lay-up and construction process, COBRA’s high-performance PVC foam sandwich windsurf board construction provided a solid starting point.  Having selected vacuum consolidated epoxy wet layup for the mix of woven and stitched biaxial reinforcements, COBRA was able to build down to the customer’s weight target with the absolute minimum of waste and additional consumables.  Top and bottom sections of the hull were moulded separately then bonded together, with the smaller outrigger hull – known as the ‘ama’ – produced in the same way.  Prepreg carbon fibre and in-house split mould tooling was also used for the two ‘Iakos’ - the two cross beams that join the ama to the main hull. 

An in-mould applied finish coat was then used for the hybrid OC-1 while the PRO carbon fibre model benefits from COBRA’s ultra-light paint system.

“COBRA is able to provide mass production capability and rapid new model turnaround, as well as delivering consistently high quality. We are delighted with the first COBRA built OC-1s and have received exceptionally positive feedback from both customers and racers” comments Baptiste Gossein.

The next ARE project to enter mass production at COBRA will be the V-1 canoe. Similar to the OC-1 but an open boat that the paddler sits inside, the V-1 will have no rudder or steering system, requiring more finesse to manage underway.

“The OC-1 outrigger canoe is a superb example of our customer focused approach to production process development.  By working closely with Baptiste and the ARE team, COBRA is able to provide mass production capability and a rapid new model turnaround, as well as delivering consistently high quality.  This is a sector in which we expect to see significant expansion over the next few years”, comments Danu Chotikapanich, CEO, COBRA International.

Neumünster – Success is built by connecting the right people with the right product. In a global marketplace, this means collaboration is just as important as competition. Companies need to focus on their strengths, while finding practical ways to innovate and expand upon their capabilities.

An exclusive license from Procter & Gamble offers the best for nonwovens

In order to do so, working together often makes the most sense. This is what motivated Procter & Gamble and Oerlikon Nonwoven – Teknoweb Materials to agree on an exclusive license agreement to market and sell the Phantom platform worldwide.

The patented process for hybrid nonwovens combines the best of both airlaid and spunmelt technologies to deliver new, flexible ways of creating wet and dry wipes. Phantom technology offers additional benefits by reducing resources and cost, while increasing overall performance. The exclusive license gives Oerlikon Nonwoven – Teknoweb Materials distribute this technology worldwide. In addition, Oerlikon Nonwoven – Teknoweb Materials have further refined the process into their own Levra technology – an entry-level option which offers tailored production volumes with lower investment costs but is still suitable to be upgraded to the premium Phantom model in the future.

Quality products that cost less

Essentially, Phantom technology was developed to produce hybrid substrates. The spunmelt and airlaid processes are merged into one step to combine cellulose fibers, long fibers such as cotton, or even powders with polymer fibers in unprecedented ways. This technology has clear advantages in terms of resources, performance, and cost compared to the previous processes on the market. By removing hydroentanglement, it is no longer necessary to dry the material. Adjusting the process can optimize relevant product characteristics such as softness, strength, dirt absorption, and liquid absorption. In the end, this even increases the quality of the product itself.

The greater freedom for formulating continuous and discrete fibers allows for more flexible and absorbent structures and highly textured materials. Wipes feel softer to the touch while providing more protection for the hands. Up to 90% of the material can consist of pulp fibers, although natural alternatives like cotton or synthetic fibers can be added to the mix.

Phantom technology has not only found a practical application in a variety of wipes – such as hygiene wipes, anti-bacterial wipes, surgical wipes, or industrial wipes – but also in absorbent cores, for instance indiapers or fempro products. With so many applications, Oerlikon Nonwoven – Teknoweb Materials are fully prepared to deliver Procter & Gamble’s innovative Phantom technology to the global nonwovens market.

• Specialised in dye-sublimation printing, the Italian company has conquered the heights of the high fashion sector with its top-quality printed fabrics.
• With its recent investment in a direct-to-fabric printing line, Digitak is preparing to expand its range of printed products, focusing on fabric differentiation.

Dye sublimation printing of high fashion designs is the beating heart of Digitak, an Italian company specialised in digital textile printing. Operating in the textile district of Lombardy, Italy, the company has established itself among the main suppliers in the world of high fashion and sportswear in just under 15 years.

Making production versatility one of the cornerstones of its philosophy, Digitak has continued to invest in technology, as well as research and development its product portfolio. This forward-thinking approach has enabled the company to guarantee innovative, personalised products with meticulous attention to detail, with the highest – almost obsessive – standards of quality and maximum design flexibility. Over the years, the extensive experience gained by the company’s management in the field of sublimation with traditional and digital techniques, combined with their investment decisions have allowed Digitak to enhance its production performance, gradually implementing higher quality standards and differentiating itself from the competition in the complex and competitive sector of high fashion. An important feat, which has not, however, dampened its enthusiasm and willingness to continue growing and exceeding its goals. The company’s latest investment in a direct-to-fabric digital printing line with pigment ink propels the company into a new and promising production dimension.

Sublimation printing specialists

Since Digitak’s establishment, Filippo Taccani, the founder and current owner of the company, had set himself a clear and ambitious objective: “I wanted to take up the challenge of operating digitally - printing fabrics using this innovative technology to create products on a par with those  I had achieved with traditional sublimation textile printing methods during my previous work experience.”

The purchase of a Mimaki JV4 plotter, one of the first to be installed in Italy, marked the beginning of Digitak’s adventure. “To start the business, I needed a printing system that could operate with dispersed inks to print on polyester and I found the JV4 to be the best option,” explains Taccani. “It was an excellent decision, because I used these plotters to build the company and its success.”

The first Mimaki plotter was in fact followed by a second and a third. When it bought the fifth, the company moved to an industrial unit in Tradate (Varese) – Digitak’s current site – which now houses around fifteen Mimaki JV33 plotters, in addition to three Mimaki TS500-1800 wide-format sublimation printers, and a Mimaki TS300P-1800 high-speed sublimation printer. This Mimaki powered production facility – which is one of the company’s core strengths – was recently expanded with the addition of a Mimaki TX300P-1800B belt-type hybrid printing system, together with a Mimaki TR300-1850C textile coater and a Mimaki Tiger-1800.

“Naturally, over the years, we have also tested printing systems from other suppliers, but we have always returned to Mimaki. With high fashion as our key market, we need to guarantee our customers the highest levels of quality and, to date, we have never found solutions that beat the quality of this Japanese brand’s technology.”

According to Taccani, the difference lies in the “calligraphy” of Mimaki’s machines, that is the line of the ink on the fabric: “Unlike its competitors, Mimaki has focused on the ‘waveforms’, i.e. the electronics associated with the print heads. This attention paid to the way the ink jet is managed from the print head has allowed Mimaki to achieve unparalleled levels of accuracy, an aspect that has given my company a clear competitive edge.”

Moreover, at Digitak, quality comes before quantity: “We prefer to dedicate an extra day to production to guarantee the customer a final product that fully meets requirements and expectations. Mimaki’s technology not only suits this business model bult on top quality, but it crucially enables it.”

Operational and creative flexibility

Digitak currently prints around 2,000 linear metres of fabric per day. Its portfolio ranges from clothing and scarves, to beach and swimwear, with related personalised accessories, to sportswear, with technical properties such as breathability, comfort, resistance to external agents. The company have even added customised outdoor furniture to their offering of diverse and creative products.
The company’s machines operate continuously, 24/7. During the day, the machines are mainly used to develop and produce samples and colour proofs, while the actual production is carried out at night. “Thanks to our technology, we have developed an extraordinary operational flexibility. The fact that we have so many plotters allows us to work on multiple designs at the same time and to launch projects that are also very different from one another,” explains Taccani. “There are also some other crucial factors that have contributed, and continue to contribute, to increasing our production efficiency. The reliability of Mimaki’s solutions and the remote monitoring option offered is key. Once the standard start-up monitoring has been carried out and the machines are found to be printing correctly, we can let them work overnight without an operator. This is a great benefit for people who, like us, manage such a large and diverse fleet of machines.”

Digitak takes the same approach to customer service. Faced with an increasingly demanding market in terms of creativity, precision and completeness of service, the company wants to guarantee flexibility and customisation. “We decided to set up a department dedicated to the pre-press stage, in charge of preparing and checking the files supplied by customers. Seldom do our teams not need to do some editing of the files supplied, even if it’s only to make small changes that are essential for the print document to be as suitable as possible and to achieve the best final result.”

Technologies of the future

With a view to further enhancing production and customer service, Taccani has chosen to take on a new challenge, switching things up with some of the most recent investments.

While maintaining the focus on dye sublimation printing, Taccani has focused on technological diversification by installing a direct-to-fabric digital printing line. This consists of a Mimaki TX300P-1800B printing system with pigment inks and a TR300-1850C coater from Mimaki’s TR series. “The market continues to evolve and now requires even more flexibility regarding both processes and the fabrics supplied. This means that great opportunities exist for a print shop capable of simultaneously producing the same design – with minimal colour adjustment – on different fabrics, guaranteeing similar and accurate results. And this is precisely the path we are taking,” says Taccani. “Why have we opted for Mimaki again? Well, I had an opportunity to try out their new pigment inks and I immediately realised that they are a generation ahead of the other pigments available on the market. The cyan is very clean, the black is deep and there is a very interesting fullness of colour, suitable not only for furnishings, but also for other applications in the clothing sector.”

With its pigment inks, the new direct-to-fabric printing line allows Digitak to explore other related market segments. Thanks to the innovative automatic belt system, the TX300P-1800B guarantees good productivity and high-quality results. A standard of quality that is also boosted by the TR300-1850C fabric pre-treatment system: “This coater is essential for ensuring the best possible preparation of fabrics for printing. In fact, we are able to treat fabrics to make them suitable for the type of print they are intended for, sanitise them for specific applications and, in some cases, even dye them, with excellent quality.”

According to Taccani, another beneficial factor of direct-to-fabric pigment printing technology is the eco-sustainability of the process and its lower environmental impact. “We are proud to be able to offer our customers excellent printing results using little water and printing in ‘green mode’, with both the technologies we have available. I consider them winning technologies for the future, as both dye sublimation printing and direct-to-fabric printing with pigment inks use little water while mainly requiring the use of energy. Therefore, if you use renewable energy, then you’re done.”

Digitak’s other trump card is the Tiger-1800 installed in 2019. With this industrial printing system, the company aims to increase production volumes while maintaining its high-quality standards and further optimising costs. “We are excited to have these promising technologies available to us in-house. We are currently experimenting with these solutions, testing new opportunities and evaluating which paths to take to stay ahead of the game,” concludes Taccani.

• New composite e-Mobility application
• Multi-year substantial contract

After prototypes for a Chinese automotive manufacturer, a major order from a North American automaker, and yet another order for a European sports car manufacturer, SGL Carbon has now been nominated by BMW Group to produce a cover component for battery enclosures in series. This substantial multi-year order will include the production of an innovative glass-fiber-based cover plate for the battery housing for usage in a future plug-in hybrid model of BMW Group.

Materials made of composites are suited for battery enclosures for different reasons: Besides their light weight, which enhances the electric vehicle’s range, fiber-reinforced plastics offer high stiffness. In addition, they meet high requirements for water and gas tightness and feature excellent fire protection properties. Composite materials can also help to achieve improved structural stiffness of the underbody, e.g. to protect against penetration, as well as an optimized thermal management. Carbon fibers are ideal for especially stressed structures or load-bearing elements, such as the underbody panels and side frames. For components subjected to less stress, such as battery box covers, glass fibers or a fiber mix may suffice.

In addition to the new application for the hybrid model battery enclosure, SGL Carbon will continue producing the usual components made of carbon-fiber-reinforced plastic for the BMW i3 and delivering materials for the Carbon Core body of the BMW 7 series, and has been nominated as the supplier for all carbon materials - fibers, textiles, stacks - for the BMW iNEXT, set to be launched in 2021.

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.

• 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.

At the Composites Europe in Stuttgart /06 - 08 November 2018), the Institut für Textiltechnik of RWTH Aachen University, short ITA, will be showing products, components and machines along the fibre composite process chain. The ITA will present itself at the booth of the Aachen Center for Integrative Lightweight Construction (AZL) in hall 9, booth E70. Various demonstrators will be used to present selected innovative processes and products over the individual steps. The exhibits come from different fields of application: From mobility applications to the construction sector. Here is an example from the field of "construction composites":

With the concrete bar stool with hybrid carbon reinforcement, the ITA demonstrates that textiles as reinforcement structures for concrete elements allow a enormous geometrical freedom of Design. So far, manual positioning of the textile reinforcement used to be time-consuming and complex, as permitted tolerances are in the millimetre range. Thus the production mainly contributed to the high costs of textile concrete.

At the ITA, the two industrial partners Albani Group GmbH & Co. KG and DuraPact 2.0 Kompetenzzentrum Faserbeton GmbH developed a new hybrid reinforcement with integrated spacer. This hybrid reinforcement reduces the time required to position the reinforcement by up to 60 percent and thus makes the material significantly more

The new, cost-effective hybrid reinforcement contains an integrated spacer and thus faciliates the positioning of dry and coated reinforcements. The integrated spacer allows several layers of reinforcement to be stacked quickly, allowing the desired degree of reinforcement to be set. The hybrid reinforcement consists of a carbon or glass fibre grid joined with a permeable polyamide mat and will be available in roll form from industrial partners in the near future.

At the Munich Fabric Start in Munich, TINTEX proudly announced its complete switch from the use of conventional cotton and the concomitant launch of a new fabric range that is the highest expression of the new generation of cotton: Naturally Advanced Cotton by TINTEX.

This new range is able to offer an advanced smart choice of 4 different premium and responsible advanced cotton solutions such as BCI Cotton, ECOTEC® by Marchi & Fildi, GOTS certified organic cotton and Supima.
