From the Sector

•    First production supercar created with Hypetex coloured carbon fibre
•    Paint-replacement technology reduces weight to enhance performance

British car manufacturer Briggs Automotive Company (BAC) has created a unique Hypetex coloured carbon fibre version of its Mono R, reducing the weight by removing the need for paint.  

The original BAC Mono R was created to be lighter and more powerful than the standard model, with 343bhp and 555kg total weight, equating to a power-to-weight ratio of 618bhp-per-tonne. By removing the need for paint coatings in this version, the net weight of the exterior is reduced compared to a painted shell, resulting in a further improved overall performance.

The car’s body was created using Hypetex’s titanium carbon fibre twill, and finished with a crystalized lacquer, offering a unique aesthetic finish. The ultra-lightweight supercar can accelerate from zero to 60mph in less than 2.5 seconds.  

Hypetex’s paint-replacement technology retains the visible weave, allowing for a bold design and a choice of colours without technical compromises, perfectly aligning with BAC’s initiatives to maximise performance whilst creating bespoke supercars. Paint generally adds 138 grams per metre squared, whereas Hypetex adds just 17 grams for the same area, offering an 8x weight saving.
This bespoke version of BAC’s single-seater Mono R was subject to BAC’s renowned BAC Bespoke programme, which ensures that no two Monos are the same. The client, a US-based collector, worked with BAC’s design team to design the car to their personal taste.   

Born out of Formula 1 technology, Hypetex offers manufacturers sustainable aesthetic materials with technical and efficiency benefits. This collaboration is an all-British success story, with the Hypetex carbon fibre body built by Formaplex, a leading UK-based manufacturing company who manufacture lightweight engineered solutions for top tier customers in Automotive, Aerospace and Defence markets. BAC’s supply chain is 95% UK-based.  

Hypetex continues to expand its growing portfolio of the use of coloured carbon fibre to add personalisation to the automotive field, with its material recently featured on the 2024 Ford Mustang Dark Horse.

RadiciGroup took part in the Phygital Sustainability Expo, this year in its fourth edition, which was held in Rome on 5 and 6 July. This event is entirely dedicated to the ecological transition of fashion and design brands through technological innovation. The show is an important platform for discussion on sustainable transition issues, involving Italian and international brands, fashion tech start-ups, representatives from the institutional, business and educational fields, and consumers.

RadiciGroup's participation in the event was further evidence of the Group's commitment to making a contribution to sustainability and circularity in the fashion and textile industry, in collaboration with all the other players in the supply chain. During the narrated fashion show, held on the evening of Wednesday, 5 July, in the evocative archaeological complex of the Imperial Forum Museum, RadiciGroup presented a maxi dress made of Biofeel® eleven, a yarn of completely natural origin featuring high technical, aesthetic and environmental performance. This yarn is produced starting from a small bean cultivated in India on semi-arid land and thus does not compete with human food production. These beans yield a special oil ideal for obtaining biopolymers, such as the one produced by Arkema and spun into yarn at RadiciGroup in Italy.

The dress is not only made from a low environmental impact raw material, but is also an example of ecodesign: the garment was realized on a Shima Seiki WholeGarment knitting machine, where the entire item was knit directly from spools of Biofeel® eleven yarn, bypassing the traditional stages of weaving and tailoring. It is a zero-waste process, as only the quantity of yarn strictly needed for the garment is used.

Biofeel® eleven yarn endows the dress with unique characteristics, including low moisture absorption, greater lightness and high resistance and durability. Besides being 100% biobased, the yarn is also 100% recyclable because it is made of a mono-material polymer, which facilitates its end-of-life recycling and processing into new materials suitable for any application requiring high performance.

"ITA Aachen and ITA Augsburg are part of the ITA Group International Centre for Sustainable Textiles. Experience our textile innovations at two exhibition booths," explains ITA Institute Director Professor Dr. Thomas Gries. "See our ring spinning tester at booth H3-B304, which spins recycled fibres sustainably and individually in a previously impossible fineness. In addition, there is digital yarn monitoring, which enables new market potentials. Get an idea of the Recycling Atelier of ITA Augsburg at booth H3-A207 and see the textile cycle from used textile to solution steps for industrial implementation together with industry partners. Join us on the Walk4Recycling and follow the path from used textile to a new knitted pullover on a tour of the trade fair. This is how we live up to our claim as the ITA Group: sustainable - digital - individual."

ITA Aachen - Digital ring spinning tester for recycled fibres enables spinning of fine yarns with high recycled fibres content
The Institut für Textiltechnik of RWTH Aachen University (ITA) will be exhibiting a digital ring spinning tester, which spins recycled fibres directly and conventionally with a particularly high content of 60-70 percent. Up to now, recycled yarns have mainly been rotor-spun in this blend ratio. This results in rather coarse yarns and is not suitable for finer textiles such as outerwear. Ring spinning of recycled yarns now enables the spinning of finer yarns and thus a higher application level for recycled materials.

A unique selling point of the ITA ring spinning tester is the simultaneous spinning in the direct spinning process from the sliver and in the classic ring spinning process. For this purpose, the strength and elongation of the spun yarn are determined online and digitally for the first time. The real-time measurement allows process parameters and yarn properties to be adjusted iteratively and quickly. The ring spinning tester was upgraded from an existing tester to Industry 4.0 standard and is operated via a tablet. Operation via tablet enables the adjustment of process parameters including online quality monitoring remotely from anywhere in the world.
 
For this purpose, the ring spinning tester is also able to produce fine ring spun yarns. These yarns made from recycled material opens up a multitude of further fields of application for woven and knitted goods. Now, for example, clothing and technical textiles can be made from recycled material, the production of which was not possible before - such as outerwear made from recycled material. The development of new industries and fields of application opens up new market potential for recycled yarns - also and especially for processing in Europe. This creates the opportunity to preserve key technologies and jobs in cost-intensive locations.

ITA Augsburg - Recycling Atelier: Walk4Recycling
The Recycling Atelier of the Institut für Textiltechnik Augsburg gGmbH on stand H3-A207 presents the textile recycling from used textiles into new products via the various process steps and, together with the industrial partners, opens up solution paths for industrial implementation.

Under the headline "Walk4Recycling", a tour of the fair shows the cycle of used textiles from used knitwear into a new knitted pullover via a ring yarn made from a blend of 65 percent recycled cotton and 35 percent virgin polyester. The key innovation here is the high proportion of recycled fibres from post-consumer textiles for a ring yarn of this fineness. Today, mainly coarse rotor yarns for low-quality textiles are spun from these materials. The industrial partners participating in the Walk4Recycling are partners of the Recycling Atelier and contribute with their technologies to the fact that fibre material from old clothes can be processed in various process stages into a yarn of new value and high-quality ready-made garments.

The Walk4Recycling offers visitors the opportunity to experience a complete recycling cycle with the numerous process stages from tearing the old textiles, preparing and spinning the fibres and knitting a new jumper live during the fair. Get detailed information on the mechanical recycling of clothing via QR code, website and flyer about the participating exhibitors and their machines and technologies. A short movie will give you additional insights into the various processes involved in the production of the jumper.

The Organic Cotton & Textiles Conference, taking place in Indore, India over three days, from February 27-March 1^st is set to bring together a diverse group of key players from every part of the textile supply chain. Farmers, farm groups, industry representatives, non-profits, academics, suppliers, brands, certifiers, government representatives and policymakers will join nearly 200 guests at the multi-day event. The aim is to foster collaboration, explore innovative ideas, listen to those on the ground and focus discussions to develop a shared vision to boost the organic textile supply chain worldwide.

Co-hosted by  OCA, GOTS, and IFOAM - Organics International, the conference will address a range of subjects including social conditions, transparency through innovation, scaling up organic through investment, as well as sessions tackling certification, decent work and environmental impacts. The event also gives voice to farmers, who join as panellists, in a dedicated Q&A session with seven organic cotton farmers from the region. On the third day, organised by OCA, the organic farmers will welcome attendees to their communities during field trips west to Petlawad to witness organic practices at ground level.

“By addressing these important issues and fostering a dialogue between participants, the conference aims to develop innovative solutions that can drive progress and growth in the sector", says Bart Vollaard, Executive Director of OCA. "We are thrilled to be joining forces with GOTS and IFOAM to create positive change in the organic textile sector."

“Together with IFOAM - Organics International and OCA, GOTS wants to increase visibility of organic and at the same time enhance integrity of organic fibres and textiles.

Valérius 360 wanted to make a sustainable, circular approach possible in the fashion industry. Working together with Trützschler, a collaborative project has now achieved high-quality recycled yarn – opening up massive potential to drive measurable progress toward a circular and sustainable textile industry.

Testing at the Trützschler Technical Center
The team from Valérius 360 wanted to find ways of improving the processes for yarns made from 50 % recycled and 50 % virgin cotton (Ne30). In particular, it was seeking ways to reduce thick and thin spots, which disturb the appearance of the textile surface.

At the Trützschler Technical Center in Mönchengladbach, they conducted special trials that showed that using a direct spinning process for this application delivers much better results than a process with a draw frame passage for rotor yarns.

In direct spinning, the sliver from the card is directly drawn in the draw frame which is integrated in the can stock. This involves one less process step than using an autoleveller draw frame, while also saving space and giving staff more time for other operations.

On-site support from Trützschler Customer Service
The team from Valérius 360 also received in-house training from the Trützschler Customer Service department. Together, they analyzed and significantly improved the process at the Valérius 360 production site. This helped to bring yarns made from recycled raw materials up to the required level of the 50% Usterstatistics. This is the reference level for yarns made from virgin raw materials. Accordingly, 50 % of all yarn producers with raw cotton for rotor yarns and comparable yarn counts produce a poorer quality.

The Lenzing Group, a leading supplier of sustainably produced specialty fibers, and Renewcell, the Swedish textile-to-textile recycling pioneer, have signed a multi-year supply agreement to accelerate the transition of the textile industry from a linear to a circular business model. The agreement contains the sale of 80,000 to 100,000 tonnes of Renewcell’s 100 per cent recycled textile Circulose® dissolving pulp to Lenzing over a five-year period, for use in the production of cellulosic fibers for fashion and other textile applications.

“The textile industry must change. By signing the agreement with Swedish textile-to-textile recycling company Renewcell, Lenzing is able to further integrate recycling and accelerate the transition of the textile industry from linear to circular. As champions of sustainability, we know that moving towards a circular economy is vital to address the enormous textile waste challenges of the industry”, says Christian Skilich, Chief Pulp Officer of the Lenzing Group.

“Lenzing is a major player in our industry, with an inspiring track record of path-breaking technical excellence and sustainability leadership. Our new partnership fits perfectly into Renewcell’s strategy to accelerate the scale-up of circular materials by collaborating with fashion’s most important players. We are more than pleased to join forces with Lenzing with the shared goal of making fashion circular.” said Patrik Lundström, CEO of Renewcell, in a comment on the agreement.

Canopy, a not-for-profit environmental organization dedicated to protecting forests, species, and climate, welcomes the agreement between Lenzing and Renewcell.
“Accelerating the transition to low-impact, circular production is the challenge of the decade for the fashion industry. That is why this partnership between Renewcell and Lenzing is so refreshing – it will bring low-carbon Next Gen solutions to market at scale,” exclaimed Nicole Rycroft, Executive Director of Canopy. “With the climate and biodiversity clocks ticking, the race to circularity is one we need all companies to win.”
 
It is an essential part of Lenzing’s corporate strategy and ambitious sustainability targets to become a true champion of circularity and to offer TENCEL™ and LENZING™ ECOVERO™ branded specialty textile fibers with up to 50 percent post-consumer recycled content on a commercial scale by 2025. To reach this goal Lenzing partners with recycling pioneers like Renewcell.
Circulose® originates 100 per cent from textile waste, like old jeans and production scraps, and turns into dissolving pulp. It transforms textile waste and production scrap into new high-quality textile products.

The future of e-mobility will be determined in particular by safe battery enclosures. As batteries for electric vehicles become more performant, higher volumetric energy density plays a crucial role. If more energy is to be stored in less installation space, new material and design solutions are required. The development of suitable enclosures made of safe and highly robust lightweight materials is also required. This is a case for the Aachen Centre for Integrative Lightweight Production (AZL). A project on cell-to-pack battery enclosures for battery-electric vehicles, which has been eagerly awaited in the industry, will start in October this year there.

The design of battery housings is crucial for safety, capacity, performance, and economics. The Cell-to-Pack project, which is starting now, will focus on developing concepts for structural components and for producing them based on a variety of materials and design approaches. The concepts will be compared in terms of performance, weight and production costs, creating new know-how for OEMs, producers and their suppliers throughout the battery vehicle value chain. Companies are now invited to participate in this new cross-industry project to develop battery enclosure concepts for the promising and trend-setting cell-to-pack technology.

The basis for the project is the lightweight engineering expertise of the AZL experts, which they have already demonstrated in previous projects for multi-material solutions for module-based battery housings. Together with 46 industry partners, including Audi, Asahi Kasei, Covestro, DSM, EconCore, Faurecia, Hutchinson, Johns Manville, Magna, Marelli and Teijin, 20 different multi-material concepts were optimized in terms of weight and cost and compared with a reference component made from aluminum. All production steps were modelled in detail to obtain reliable cost estimates for each variant. Result: depending on the concept, 20% weight or 36% cost savings potential could be identified by using multi-material composites compared to the established aluminum reference.

It is expected that the design concept of battery enclosures will develop in the direction of a more efficient layout. In this case, the cells are no longer combined in modules in additional production steps, but are integrated directly into the battery housing. The elimination of battery modules and the improved, weight-saving use of space will allow for higher packing density, reduced overall height and cost saving. In addition, various levels of structural integration of the battery housing into the body structure are expected. These new designs bring specific challenges, including ensuring protection of the battery cells from external damage and fire protection. In addition, different recyclability and repair requirements may significantly impact future designs. How the different material and structural options for future generations of battery enclosures for the cell-to-pack technology might look like and how they compare in terms of cost and environmental impact will be investigated in the new AZL project. In addition to the material and production concepts from the concept study for module-based battery enclosures, results from a currently ongoing benchmarking of different materials for the impact protection plate and a new method for determining mechanical properties during a fire test will also be incorporated.

The project will start on October 27, 2022 with a kick-off meeting of the consortium, interested companies can still apply for participation until then.

• 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.
