From the Sector

The company’s principle theme at Techtextil was Sustainability, since FET extrusion systems are ideally suited for both process and end-product development of sustainable materials. These systems are designed to be material efficient, can be bespoke designed and offer both flexibility and a high level of processing capability. They are supplied as self-contained units for ease of installation in a laboratory or small scale process evaluation environment.

FET’s enhanced Fibre Development Centre enables clients to develop and trial their own sustainable fibres and FET has now successfully processed almost 30 different polymer types in multifilament, monofilament and nonwoven formats

The innovative stand at Techtextil was specifically designed to highlight FET’s total commitment to all aspects of sustainability. It utilised as many sustainable components as possible and met with much comment and approval from visitors.

Fibre Extrusion Technology Limited (FET) of Leeds, England enjoyed another successful Techtextil in Frankfurt, with high quality enquiries from technical companies and organisations worldwide, but in particular from customers based in Europe.

• Exceptional achievement of research work on the use of Nuclear Magnetic Resonance (NMR) spectroscopy for understanding PET depolymerization enzymes

Carbios (Euronext Growth Paris: ALCRB), a pioneer in the development of enzymatic solutions dedicated to the end-of-life of plastic and textile polymers, announces the publication of an article entitled “An NMR look at an engineered PET depolymerase” in the scientific journal Biophysical Journal.

The article describes the use of Nuclear Magnetic Resonance (NMR) spectroscopy to study the thermal stability of PET depolymerization enzymes and the mechanism of adsorption of the enzyme on the polymer. This innovative approach, which required months of development, is a world first and opens up new ways of improving these enzymes. This publication confirms Carbios' international lead in the development of the most efficient enzymes for the depolymerization and recycling of plastics.

Prof. Alain Marty, Chief Scientific Officer of Carbios and co-author of the article, explains: “ Nearly 25 researchers are currently working on our unique enzymatic technology. It is based on academic collaborations with the world's leading experts in their fields..”

Dr. Guy Lippens, CNRS Research Director and co-author of the artcle, adds: “Nuclear Magnetic Resonance (NMR) is an extraordinary biophysical technique for visualizing an enzyme directly in solution. Our study is the first to use NMR as a complementary technique to crystallography and molecular modeling to observe a PETase. This gives new perspectives to better understand the functioning of these enzymes and it makes it possible to imagine new ways of improving these enzymes. ”

With the goal of making recycling of lightweight, high-volume fiber and flake recyclate much more economical and, in some cases even possible, Coperion has developed a new version of its ZS-B side feeder. Using the innovative ZS-B MEGAfeed, plastic recyclate with a bulk density under 200 kg/m³, long considered intake-limited and thus not worth recycling, can be reliably fed in large quantities into Coperion’s ZSK twin screw extruder and be concurrently recycled and compounded.

The ZS-B side feeder’s novel design makes it possible to feed very high rates of fiber and flakes, such as PA, PE, PET, and PP. As a result, the ZSK twin screw extruder’s high capacity can be fully exploited when the ZS-B MEGAfeed is used. Very high throughputs in both mechanical and chemical recycling of post-industrial and post-consumer waste are achieved.

Increased Throughput in Numbers
With a ZSK 58 Mc18 twin screw extruder, the throughput increase and thus the potential of the new ZS-B MEGAfeed becomes very clear. When recycling PA fibers with a bulk density of ~40-50 kg/m3, throughputs of 70 kg/h were previously achieved using conventional equipment. When the PA fibers were fed into the ZSK extruder using the ZS-B MEGAfeed, throughputs increased about fourteenfold to 1,000 kg/h. Similar results were achieved recycling carbon fibers with a bulk density of ~50-70 kg/m3; in this case, throughputs increased from 50 kg/h to 2,500 kg/h using the ZS-B MEGAfeed. When recycling PCR (Post-Consumer Recycled) flakes, throughputs increased from 50 kg/h to 700 kg/h, and from 80 kg/h to 1,300 kg/h with multilayer film flakes.

Key to Economical Recycling of A Wide Variety of Plastics
Plastics previously considered not recyclable are becoming a valuable raw material using the new Coperion ZS-B MEGAfeed. For example, PCR flakes or recyclate from carbon fiber-reinforced plastics can now be fed into the ZSK extruder at high feed rates and recycled economically.

In the case of mechanical upcycling, upstream processes necessary for compounding, such as compacting, melting and agglomeration, are completely eliminated using the ZS-B MEGAfeed technology. In this recycling process, flakes and fibers can be fed directly into the ZSK extruder, where they are melted, compounded, devolatilized, and filtered in a single step. In so doing, both investment costs and energy consumption drop. The production process becomes significantly more efficient. Moreover, the thermal product stress is reduced and recyclate quality increases.

Even when recycling PET, the feed rate is no longer a limiting factor. With the ZS-B MEGAfeed, PET flakes and fibers can be fed into the ZSK twin screw extruder in large quantities with no pre-drying or crystallizing, where they can be processed with the highest degree of profitability.

The ZS-B MEGAfeed can also feed large quantities of post-consumer waste, adding appreciable value to the chemical recycling process with the ZSKs. ZSK throughput rates are very high with the ZS-B MEGAfeed. Preheating of the recyclate via mechanical energy input of the twin screws thus becomes even more economical for further processing in the reactor.

Existing Coperion extruders can be retrofitted with ZS-B MEGAfeed technology to greatly expand their spectrum of applications and increase their throughput rates.

• Finnish fashion and textile technology company Infinited Fiber Company plans to build its first commercial-scale Infinna™ fiber factory at Stora Enso’s Veitsiluoto industrial site in the city of Kemi in Finland’s northernmost region of Lapland. Infinited Fiber Company plans to convert a building currently housing a discontinued paper production line.
• The size of Infinited Fiber Company’s planned investment is around EUR 400 million.
• The planned factory is expected to create around 270 jobs at the Veitsiluoto industrial site.
• The factory is expected to operate at full capacity in 2025.

Fashion and textile technology company Infinited Fiber Company plans to build a commercial-scale factory to produce regenerated textile fiber for the world’s leading apparel companies at the site of renewable materials company Stora Enso’s closed Veitsiluoto paper mill in Kemi, a Finnish city on the northern shore of the Baltic Sea. The size of the investment is estimated at EUR 400 million, and it is expected to create around 270 jobs in the area. The annual fiber production capacity of the planned factory is expected to be 30,000 metric tons, which is equivalent to the fiber needed for about 100 million T-shirts.  

Infinited Fiber Company’s technology enables cotton-rich textile waste to be transformed into a versatile, high-quality regenerated textile fiber called Infinna™, which looks and feels like cotton. Major international fashion and apparel companies – including Zara’s parent company Inditex, PVH Europe, which is known for the Tommy Hilfiger brand, Patagonia, PANGAIA, H&M Group and BESTSELLER – have already committed to Infinna™ purchases through multi-year agreements as they look for materials that enable the industry to shift towards circularity. Infinited Fiber Company expects to export most of the output of its planned factory. This makes Kemi an ideal location as the city’s port serves as an efficient link to the rest of the world.

Infinited Fiber Company will convert a building housing a discontinued paper production line into an Infinna™ fiber factory. Both the factory engineering and project implementation as well as the related financing negotiations were commenced at the beginning of the year and are progressing well. Infinited Fiber Company has also agreed on the provision of energy and water related services with utility infrastructure company Nevel.

Once up and running, the factory is expected to provide direct employment for around 220 people, and for a further 50 through on-site support functions such as services, maintenance, and logistics. The additional indirect employment impact is estimated to be around 800 jobs. The construction and installation phase is expected to create jobs equaling around 120 person-years. The factory is anticipated to operate at full capacity in 2025.

• Sustainable infrastructure solutions, road safety and health protection

At this year’s Techtextil, Oerlikon Polymer Processing Solutions will be presenting the trade audience with new applications, special processes and sustainable solutions focusing on the production of industrial textiles. Among other things, the company will be showcasing new technology for charging nonwovens that sets new standards with regards to quality and efficiency. Between June 21 and 24, the discussions will be concentrating on airbags, seat belts, tire cord, geotextiles, filter nonwovens and their diverse applications.

More polyester for airbags
Airbags have become an integral part of our everyday automotive lives. The yarns used in them are made predominantly from polyamide. As a result of increasingly diverse airbag applications and also the increasing size of the systems used, polyester is today used as well, depending on the application requirements and cost-benefit considerations. Against this background, the Oerlikon Barmag technologies make an invaluable contribution. In addition to high productivity and low energy consumption, they particularly excel in terms of their stable production processes. Furthermore, they comply with every high quality standard for airbags, which – as in the case of virtually all other textile products used in vehicle construction – must provide the highest level of safety for vehicle occupants. And all this without any loss of function in any climate and anywhere in the world for the lifetime of the vehicle.

Buckle up!
Seat belts play a decisive role in protecting vehicle occupants. They have to withstand tensile forces in excess of three tons and simultaneously stretch in a controlled manner in emergencies in order to reduce the load in the event of impact. A seat belt comprises approximately 300 filament yarns, whose individual, high-tenacity yarn threads are spun from around 100 individual filaments.

Invisible, but essential – road reinforcement using geotextiles
But it not just inside vehicles, but also under them, that industrial yarns reveal their strengths. Low stretch, ultra-high tenacity, high rigidity – industrial yarns offer outstanding properties for the demanding tasks carried out by geotextiles; for instance, as geogrids in the base course system under asphalt. Normally, geotextiles have extremely high yarn titers of up to 24,000 denier. Oerlikon Barmag system concepts simultaneously manufacture three filament yarns of 6,000 denier each. Due to the high spinning titers, fewer yarns can be plied together to the required geo-yarn titer in a more cost- and energy-efficient manner.

hycuTEC – technological quantum leap for filter media
In the case of its hycuTEC hydro-charging solution, Oerlikon Neumag offers a new technology for charging nonwovens that increases filter efficiency to more than 99.99%. For meltblown producers, this means material savings of 30% with significantly superior filter performance. For end users, the consequence is noticeably improved comfort resulting from significantly reduced breathing resistance. With its considerably lower water and energy consumption, this new development is also a future-proof, sustainable technology.

New high-tech Staple Fiber Technology Center
Extending to around 2,100 m2, Oerlikon Neumag in Neumünster is home to one of the world’s largest staple fiber technology centers. As of now, these state-of-the-art staple fiber technologies are also available for customer-specific trials.

The focus during the planning and the design of the Technology Center was on optimizing components and processes. Here, special attention was paid to ensuring the process and production parameters in the Technology Center system could be simply and reliably transferred to production systems. Here, the fiber tape processing line is modular in design. All components can be combined with each other as required. And comprehensive set-up options supply detailed findings for the respective process for various fiber products.

The Technology Center is also equipped with two spinning positions for mono- and bi-component processes. The same round spin packs are used for both processes, characterized by excellent fiber quality and properties and meanwhile very successfully deployed in all Oerlikon Neumag production systems. Furthermore, the spinning plant is complemented by automation solutions such as spin pack scraper robots, for example.

With its current position paper, the Industrievereinigung Chemiefaser e.V. takes a stand on the intense discussions about an embargo against Russian natural gas supplies. The association believes that Germany's economic and global political future can only be secured with a strong industrial base and therefore, weighing up all positions and influencing factors and assessing the consequences for labour and the market economy, cannot support a short-term natural gas embargo on Russia.

An interruption of the continuous supply of natural gas would result in immense losses for the chemical fibre companies, which could even lead to the destruction of the industry in Germany. The losses are made up of technical damage caused by an uncoordinated shutdown of plants on the one hand and market-related consequential damage caused by lost production and a lack of product sales on the other.

Depending on the location and size of the plants, a short-term outage due to a lack of natural gas would result in average losses of EUR 5 million/plant. In addition, an ongoing daily loss would have to be expected which could be in the order of e.g. 250 000 EUR/day/plant, depending on the location. Furthermore, restarting the plants is questionable if supply chains could no longer be serviced and customers globally look for other suppliers in the meantime. Thus, entire sites would be at risk. With China's global market share in man-made fiber production already exceeding 70 %, a scenario is more than realistic that China will also take over these supply chains, thus leading to an even greater dependence on China.

The vast majority of power plants used for the production of man-made fibers, especially the highly efficient combined gas-and-steam power plants based on the principle of cogeneration with efficiencies of 90 %, are designed exclusively for the use of natural gas. Quite often, there are no technical facilities for operating gas turbines or steam boilers with fuels other than natural gas. Only in exceptional cases could a switch be made to mineral oil. However, even in these cases, the necessary stockpiling of mineral oil is designed only for a short-term failure of the gas burners. A change to base-load supply with mineral oil could take a time window of between 3 and 56 months, depending on the type of plant and taking into account licensing requirements. The use of hydrogen as an energy source is only possible in the very long term. In the few cases where natural gas can be substituted, investment costs of EUR 250 million/plant can be incurred, depending on the emission level of the converted plant.

A natural gas embargo imposed by the European Union on the Russian Federation would not only mean the cessation of production and the end for man-made fiber producers, but also for other industries such as basic chemicals, paper, metal production and glass and ceramics manufacturing, as well as their related sectors. As the German economic institute Institut der Deutschen Wirtschaft Köln e. V. (IW Köln) concluded in its summary report 40/2022 of April 2022: "No one can accurately predict what future these businesses would then still have in Germany. That would be an unprecedented development."

Hypetex®, a leader in colouring carbon fibre materials, is delighted to announce that its Hypetex® Kromaskin™ field hockey stick for adidas has been selected as a finalist for the 2022 JEC Innovation Awards.

Hypetex® was commissioned by adidas to develop a market leading hockey stick differentiated from existing equipment not just by its unique pigmented carbon fibre finish, but also by its game changing hitting power and consistency. The patented range of Kromaskin™ sticks, created with support from project partners Textreme® and Marque Makers, was found to outperform competitors in a benchmark study against eight other premium hockey sticks carried out by Loughborough’s Sports Technology Institute (STI).

Hypetex® lead the design, engineering, materials, and production process development for the adidas field hockey stick project. By incorporating the stick’s finish colour within the outermost carbon fibre layer, the stick mould could be adjusted outwards, placing the highly structural spread tow materials right at the outer extremities of the mould cavity, increasing mechanical performance and maximising the structural benefits of the composite materials used.

Whilst the Kromaskin™ surface provides a stunning depth of colour with minimal finishing required after demoulding, the Hypetex® technology, including an epoxy based expanding microsphere system used in the core, delivers significant performance gains on the hockey pitch. In tests at the STI, adidas Kromaskin™ sticks had up to 16% higher coefficient of restitution (COR), meaning they will return more energy and the ball will travel faster. In addition, through the production led design and materials used, the variation in COR was 70% less than the other sticks on test, a significant reduction in the production inconsistencies common with the manufacturing of performance sporting goods.
