From the Sector

Fibre Extrusion Technology, UK is celebrating a successful INDEX20 nonwovens exhibition in Geneva, Switzerland, which closed on 22 October. Although the company has a long history in supplying meltspinning equipment for the nonwovens sector, this represents its first venture at a dedicated nonwovens show.
 
FET’s Managing Director, Richard Slack explains. “Techtextil and ITMA have previously been our main exhibitions of choice, but INDEX20 was an ideal vehicle for FET to launch our new laboratory scale spunbond system, which enables client development of nonwoven fabrics in a number of formats and polymers.”
 
FET already has spunbond systems in the field, including composite systems which utilise both spunbond and meltspun functions. The growth in global nonwovens technology, partly driven by demand for pandemic-related materials, is forecast to continue.
 
“We were delighted with the response at INDEX”, continued Richard Slack. “There was considerable interest shown in the new spunbond system and its potential for lab scale innovation. It’s clear that the industry is seeking new alternatives to synthetics at the moment, and our technology is able to assist with the testing and assessment of many of the new feedstocks being pioneered in this extremely inventive sector, where everyone is suddenly talking and cooperating with everyone else, regardless of whether they are generally competitors. We recorded in excess of 20 serious enquiries from totally new contacts and sectors, including blue chip companies in the hygiene, medical and packaging industries.”
 
“There were initial concerns about projected attendance figures, especially from China and USA companies, but we experienced good footfall from key decision makers, especially those from Europe. It was encouraging to at last experience the opportunity for face-to-face contact with old and new customers on a large scale and we are now starting to reap the benefits with enquiries continuing to flow in”.

• Hightech textiles for future-oriented construction projects

Building shells, bridges, staircases, façades ... construction projects are exposed to enormous mechanical loads. Often there are also considerable climatic or environmental influences. This has prompted the increasing use of fibre-reinforced materials in construction projects. After all, besides many other exciting properties, they offer high mechanical rigidity, low weight and excellent corrosion resistance.

Tapes, tubulars, sections and 3D woven textiles by vombaur form the perfect basis for these innovative building materials. The seamless round or shaped woven narrow textiles made of high-performance fibres are extremely loadable because they have neither seams nor welds – and therefore no undesirable breaking points. Their surface properties are identical over the entire length. In challenging tasks, composite textiles by vombaur offer a lightweight solution that is as reliable as it is durable.

Safe and durable solutions for challenging applications
The potential applications for lightweight components in the construction industry are as numerous as the project ideas of the planning and construction teams.
•    Ropes and tensioning elements made of carbon fibre reinforced plastic (CFRP)
•    Reinforcement of building structures made of concrete, steel, wood or other materials
•    Sustainable restructuring of constructions and urban districts for bridges and buildings
•    CFC slats as reinforcements in case of repairs
•    (Filled) GRP pipes made of seamless round woven tubes by vombaur as columns/pillars
•    CFRP sections as steel girder substitutes
•    Hollow profiles with individually designed cross-sections
•    Glass fibre reinforced connecting elements for glazing to minimise expansion differences between the connecting element and the glass
•    Individual light wells

• From fossil to renewable materials: Members advocate policy analysis and focused implementation of the renewable carbon strategy

The members of the Renewable Carbon Initiative (RCI) (www.renewable-carbon-initiative.com), founded in September 2020, have joined forces to shape the transition from the fossil to the renewable age for the chemical and materials industry. This means spreading the concept of renewable carbon and developing new value chains based on renewable carbon as a feedstock.

In the meantime, several activities have started from which future members can benefit as well. First and foremost is the kick-off to comprehensive policy analysis. What influence will forthcoming regulation have on chemicals, plastics, and other materials? When and where should the renewable carbon idea be emphasized and referred to?

The policy analysis will examine pending policies in the European Union – and a later expansion to America and Asia is planned as well.

A particular focus will be placed on upcoming policies and regulations and how they impact renewable carbon. The members are currently deciding on where to start specifically, but questions that may be considered are: What does the new climate law and the “Fit for 55-Package” mean for chemicals and materials? What can be expected from REACH and microplastics restrictions? How relevant is the “Sustainable Products Initiative” and the coming restrictions for Green Claims? Circular Economy, Zero Pollution and Sustainable Financing are keywords of the future European landscapes, which might become very concrete for chemistry and materials in the next few years. To what extent the concept of renewable carbon for materials is considered in policy already and how it could be further introduced in future legislation are two of the main questions investigated in the working group “Policy”.

This working group is open to all members of RCI. Policy experts provide the respective analysis as a foundation, organising discussions between members of the policy group and plan meetings with policymakers to introduce the Renewable Carbon concept.

Additional working groups have been created, one with a focus on communication, the other looking at the development of a renewable carbon label. In early September, a renewable carbon community will be launched as a starting point for even more interaction between the members, to discuss strategies, create new value chains and start project consortia.

The Renewable Carbon Initiative (RCI) is a dynamic and ambitious group of interested parties. Membership numbers have now more than doubled since the launch almost a year ago, with RCI now boasting 25 members, 6 partners and over 200 supporters. It welcomes all companies that are on the way to transform their resource base from fossil to renewable.

Circular fashion and textile technology group Infinited Fiber Company has secured investments totaling 30 million euros in its latest financing round completed on June 30. The round also brought Infinited Fiber Company new investors, including sportswear company adidas, Invest FWD A/S, which is BESTSELLER’s investment arm for sustainable fashion, and investment company Security Trading Oy. Among the existing investors contributing to this round of financing were fashion retailer H&M Group, who was the lead investor, investment company Nidoco AB, and Sateri, the world’s largest viscose producer and a member of the RGE group of companies.

This securement of new funding follows Infinited Fiber Company’s April announcement of plans to build a flagship factory in Finland in response to the strong growth in demand from global fashion and textile brands for its regenerated textile fiber Infinna™. The factory, which will use household textile waste as raw material, is expected to be operational in 2024 and to have an annual production capacity of 30,000 metric tons. The new funding enables Infinited Fiber Company to carry out the work needed to prepare for the flagship factory investment and to increase production at its pilot facilities in the years leading to 2024.

“We are really happy to welcome our new investors and grateful for the continued support from our older investors,” said Infinited Fiber Company co-founder and CEO Petri Alava. “These new investments enable us to proceed at full speed with the pre-engineering, environmental permits, and the recruitment of the skilled professionals needed to take our flagship project forward. We can now also boost production at our pilot facilities so that we can better serve our existing customers and grow our customer-base in preparation for both our flagship factory and for the future licensees of our technology.”

H&M Group is one of Infinited Fiber Company’s earliest investors. They first invested in Infinited Fiber Company in 2019.

H&M Group has also signed a multiyear sales deal with Infinited Fiber Company to secure its access to agreed amounts of Infinna from the planned flagship factory.

New investor BESTSELLER has struck a similar sales deal with Infinited Fiber Company.

In addition to strong interest by global fashion leaders, the technology has significant promise for major textile fiber producers. Allen Zhang, President of Sateri, said: “Sateri is excited to continue to invest in and collaborate with Infinited Fiber Company as part of our long-term commitment towards closed-loop, circular and climate-positive cellulosic fibers. This financing round marks a major milestone for our collaboration in scaling up next-generation fiber solutions.”

Infinited Fiber Company’s flagship plant preparations are also proceeding on other fronts. Several Nordic and international investment banks have given Infinited Fiber Company proposals on the financing options for the investment.

Infinited Fiber Company’s technology turns cellulose-based raw materials, like cotton-rich textile waste, into Infinna, a unique, premium-quality regenerated textile fiber with the natural, soft look and feel of cotton. Infinna is biodegradable and contains no microplastics, and at the end of their life, garments made with it can be recycled in the same process together with other textile waste.

• Fraunhofer, SABIC, and Procter & Gamble join forces
• The Fraunhofer Cluster of Excellence Circular Plastics Economy CCPE and its Institute for Environmental, Safety and Energy Technology UMSICHT have developed an advanced recycling process for used plastics.
• The pilot project with SABIC and Procter & Gamble serves to demonstrate the feasibility of closed-loop recycling for single-use facemasks.

Due to COVID-19, use of billions of disposable facemasks is raising environmental concerns especially when they are thoughtlessly discarded in public spaces, including - parks, open-air venues and beaches. Apart from the challenge of dealing with such huge volumes of essential personal healthcare items in a sustainable way, simply throwing the used masks away for disposal on landfill sites or in incineration plants represents a loss of valuable feedstock for new material.

“Recognizing the challenge, we set out to explore how used facemasks could potentially be returned into the value chain of new facemask production”, says Dr. Peter Dziezok, Director R&D Open Innovation at P&G. “But creating a true circular solution from both a sustainable and an economically feasible perspective takes partners. Therefore, we teamed up with Fraunhofer CCPE and Fraunhofer UMSICHT’s expert scientists and SABIC’s Technology & Innovation specialists to investigate potential solutions.”

As part of the pilot, P&G collected used facemasks worn by employees or given to visitors at its manufacturing and research sites in Germany. Although those masks are always disposed of responsibly, there was no ideal route in place to recycle them efficiently. To help demonstrate a potential step change in this scenario, special collection bins were set up, and the collected used masks were sent to Fraunhofer for further processing in a dedicated research pyrolysis plant.

“A single-use medical product such as a face mask has high hygiene requirements, both in terms of disposal and production. Mechanical recycling, would have not done the job”, explains Dr. Alexander Hofmann, Head of Department Recycling Management at Fraunhofer UMSICHT. “In our solution, therefore, the masks were first automatically shredded and then thermochemically converted to pyrolysis oil. Pyrolysis breaks the plastic down into molecular fragments under pressure and heat, which will also destroy any residual pollutants or pathogens, such as the Coronavirus. In this way it is possible to produce feedstock for new plastics in virgin quality that can also meet the requirements for medical products”, adds Hofmann, who is also Head of Research Department “Advanced Recycling” at Fraunhofer CCPE.

The pyrolysis oil was then sent to SABIC to be used as feedstock for the production of new PP resin. The resins were produced using the widely recognized principle of mass balance to combine the alternative feedstock with fossil-based feedstock in the production process. Mass balance is considered a crucial bridge between today’s large scale linear economy and the more sustainable circular economy of the future, which today is operated on a smaller scale but is expected to grow quickly.

“The high-quality circular PP polymer obtained in this pilot clearly demonstrates that closed-loop recycling is achievable through active collaboration of players from across the value chain”, emphasizes Mark Vester, Global Circular Economy Leader at SABIC. “The circular material is part of our TRUCIRCLE™ portfolio, aimed at preventing valuable used plastic from becoming waste and at mitigating the depletion of fossil resources.”

Finally, to close the loop, the PP polymer was supplied to P&G, where it was processed into non-woven fibers material. “This pilot project has helped us to assess if the close loop approach could work for hygienic and medical grade plastics”, says Hansjörg Reick, P&G Senior Director Open Innovation. “Of course, further work is needed but the results so far have been very encouraging.”

The entire closed loop pilot project from facemask collection to production was developed and implemented within seven months. The transferability of advanced recycling to other feedstocks and chemical products is being further researched at Fraunhofer CCPE.

Teijin Limited announced today that its Tenax™ carbon fiber prepreg has been adopted for a part of nacelle, or streamlined housing, for next-generation aircraft engine to be used by Airbus. A prototype of the nacelle part, which Nikkiso Co., Ltd. is developing for Airbus’s Propulsion of Tomorrow project, will be delivered to Airbus by the end of 2021.

The Tenax™ prepreg used for the nacelle part was developed especially for aircraft applications using high-performance and rapid-curing epoxy resin. Notably, the Tenax™ prepreg can be molded at a lower temperature and in a shorter time than conventional prepregs for aircraft applications. In addition to general autoclave molding, the Tenax™ prepreg also is suited to press molding for mass production, achieving excellent quality required for aircraft applications. Furthermore, it is compatible with automated fiber placement (AFP) therefore can be combined with automatic laminating technology and short-time molding to maximize production efficiency. The excellent productivity and cost efficiency of the Tenax™ prepreg were key reasons why it was adopted for Nikkiso’s nacelle.

Teijin is intensively accelerating its development of mid- to downstream applications for aircraft, one of the strategic focuses of its medium-term management plan for 2020-2022. Going forward, Teijin intends to further strengthen its carbon fiber and intermediate material businesses to contribute to increasing global sustainability, aiming to become a company that supports the society of the future.

Sappi is expanding its product range for corrugated board applications with Fusion Nature Plus.

With Fusion Nature Plus, Sappi is launching an uncoated, fully bleached and completely recyclable virgin fibre liner. The company provides a unique variety of packaging and speciality papers. The specialist in paper-based solutions also offers a wide range of products in relation to labels. Fusion Nature Plus offers excellent printing results in flexographic, digital and offset printing processes.

• Ultra-bright, uncoated virgin fibre paper with excellent printing results
• Ideal for attractive corrugated board as well as premium shopping bags
• Can be used as topliner, liner or fluting
• Available in grammages of 80 to 130 g/m²

The virgin fibre liner is based on the concept of the successful Fusion Topliner. In contrast to the double-coated Fusion Topliner, Fusion Nature Plus has a natural, uncoated surface with a more tactile feel, in response to the growing market appetite for this type of product. The liner is also provided in very low grammages.

Fusion Nature Plus enhances brand appearance

Brand owners, corrugated board processors, manufacturers of display cartons and folding cartons as well as designers all benefit from the versatility of the new Fusion Nature Plus. In contrast to conventional uncoated liner papers, the material offers high brightness, brilliant colour reproduction and consistently high quality. These features make the product the perfect choice for corrugated board or solid board packaging, where a very bright appearance is needed for topliners, inner liners and corrugating applications. Whether used as an inlay in cosmetics or confectionery packaging, or as a liner in shipping packaging to ensure an exceptional unboxing experience, Fusion Nature Plus is called upon wherever an enhanced appearance is desired.

Another area of application is paper carrier bags, where uncoated paper qualities are often preferred.

Fusion Nature Plus is ideally suited to a range of printing processes: the product achieves outstanding results in flexographic and offset printing. The pre-treated surface and high brightness offer clear advantages with regard to primer requirements and print behaviour, especially for inkjet-based digital printing. Bernd Gelder, Head of Sales Containerboard at Sappi Europe: ‘With its exceptional print quality and impressive colour reproduction, Fusion Nature Plus particularly appeals to packaging customers who value a natural look and feel in paper. The response from the market, in which packaging based on corrugated board still needs to take on a bigger role, is enormous, of course, with the result that we have succeeded in completing a number of interesting end applications and customer projects with Fusion Nature Plus shortly after market launch.’

Virgin fibre vital for recycling

In continuous recycling use, fiber that has already been recycled is subject to a progressive weakening of quality, resulting in a weakness in the products that incorporate them, but also, crucially, over time they will ultimately degrade to a point where they become unrecoverable. As a result, a certain amount of virgin fibre needs to be introduced into the cycle on a regular basis. Without continuous virgin fibre contribution to the pulp cycle, recycled producers will in the end run out of raw material. The premium virgin fibre liner Fusion Nature Plus from Sappi plays an important role here in maintaining the quality of the recycling substrate.

Thanks to the central location of Sappi’s production site in Ehingen, Fusion Nature Plus can be supplied quickly throughout Europe. The shorter transportation distances reduce transport related fossil emissions and protect the environment. The shorter production cycles in turn ensure high availability and rapid supply.

Fusion Nature Plus is currently available in six grammages from 80 to 130 g/m² in both sheet and roll form. Sappi can also provide Fusion Nature Plus with FSC or PEFC certificates on request.
