From the Sector

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.

Cooperating alliances for lightweight technology: The European Lightweight Association (ELA) and the European Lightweight Clusters Alliance (ELCA) have decided to work together. Both European lightweight clusters are united by the common goal of giving the enormous economic and ecological potential of lightweight technology more visibility in politics, business and science at European, national and regional level. In addition, complementary expertises of work form the basis for the future partnership, from which European lightweight technology can optimally benefit.

"We see great potential in the future cooperation of the ELA and the ELCA to advance lightweight technology in Europe with combined forces," says Dr Katharina Schöps as representative of the ELCA. "In this way, we are strengthening the global competitiveness of European companies and at the same time making a significant contribution to climate protection," says Jean-Pierre Heijster of the ELA about the cooperation of the European lightweight technology networks.

Together, ELCA and ELA represent a growing network of more than 4,500 companies and more than 600 research institutions from 12 European countries active in lightweight technology across different
sectors and industries. This brings together the two largest lightweight technology communities in Europe. Lightweight solutions from Europe can thus gain visibility and be implemented more quickly in global markets.

Joining forces to strengthen lightweight technologies ́ market position at the European level ELCA and ELA want to improve the positioning of lightweight technologies and materials with joint activities and events, in particular to prioritise them on the agenda of the European Commission. The cooperation thus wants to send a clear signal to Brussels. Especially with the view to achieve European climate protection goals; lightweight technology has the potential to conserve valuable resources and reduce CO 2 emissions. At the same time, the improved sustainability with the same or even optimised performance brings valuable competitive advantages for companies. Lightweight products and technologies Made in Europe can thus become a unique selling point for European stakeholders on international markets.

With this cooperation, ELCA and ELA combine their respective strengths: ELCA, as the European Lightweight Clusters Alliance, has very successfully created a resilient pan-European innovation ecosystem for lightweight technology in recent years. ELA, on the other hand, is particularly characterised by its close ties to industrial users. As a result, the existing ecosystem is enriched and a more demand-oriented development and faster market introduction is made possible. In this way, both lightweight technology networks will complement each other optimally in the future in order to bring technology and markets together in a targeted manner.

The Saxon Textile Research Institute (STFI) will be presenting innovative highlights from research and development at Techtextil 2022, the international trade fair for technical textiles and nonwovens. In addition to a warp-knitted textile façade greening in a modular system and textile lightweight construction elements for the building sector made from hemp as a renewable raw material, the STFI will also be showing innovations from nonwovens research. The project optiformTEX is an example of the nonwovens competence: in this project, the mass per unit area was specifically influenced for the production of semi-finished products in the automotive sector. Furthermore, the Chemnitz Institute exhibits an ecological foam coating for protective textiles. Central highlight of the STFI's presence at the fair is also a mobile robot system, which demonstrates the automated loading of a small-scale bobbin creel.

Highlights at Techtextil 2022
The greened façade tile is a system with which large building surfaces can be cost-effectively greened through a simple, modular segment structure. In addition to insulating the building, the system has been created to meet the design requirements of a modern city centre; low-maintenance greening is made possible through functional integration in the textile carrier layer and coordinated plant selection.

Moulded components made of natural fibre nonwovens are increasingly used in the automotive sector. Conventional nonwovens currently have uniform masses per unit area. Technical solutions for load-oriented component reinforcement and the resulting optimised use of materials represent an enormous economic potential. The basic idea of “optiformTEX” was therefore to specifically influence the mass per unit area distribution in the pile before the semi-finished product is consolidated. As a result, a textile-technological process and the corresponding plant component were successfully developed.

Future-oriented materials are offered by developments from the field of renewable raw materials in combination with bio-based resin systems: In the “Gro-Coce” project, an innovative ceiling system was developed by combining sustainable building products and methods. Currently, a high-performance hemp-based semi-finished product as well as the steps for its reproducible production by means of textile surface formation is developed by the research team. Initial application and load tests of the hemp-based semi-finished products on wooden beams confirmed the high performance potential of the natural fibre materials.

Special functional textiles are based on composite materials with coatings or membranes. The previous production of the coatings/membranes poses ecological and health risks. At STFI, solvent-free, purely aqueous coating systems and a technology for their application were therefore developed for the protective textile sector, resulting in a breathable, waterproof and wash-resistant textile coating.

The central highlight of the STFI's presence at the fair is a mobile robot system, which demonstrates the automated loading of a small-scale bobbin creel. At the STFI, the robot is part of the “textile factory of the future”, where a play mat is woven and processed step by step along the textile chain.

• adidas TERREX athlete Laura Dahlmeier tackles Mont Blanc’s Brouillard Pillar with Thomas and Alexander Huber in the film, United By Summits
• The trio are kitted out in adidas TERREX’s new Techrock Mountaineering range
• The adidas TERREX Techrock collection gives climbers the lightweight technical wear required to defy the elements mountainside

Mountaineering is about reaching personal summits. It’s about showing your mettle, finding your freedom and winning in front of no one but yourself and nature.

It’s a version of success that adidas TERREX athlete Laura Dahlmeier is reacquainting herself with. A multiple Olympic and world champion, the German biathlete is used to the noise of winning in front of huge crowds. Now retired, Laura is reconnecting with the challenges of a sport that first gave her a taste of freedom as a child: climbing.
Laura sets herself a particularly formidable goal in United By Summits. In the film, she is joined by German climbing brothers Thomas and Alexander Huber for an ascent of Mont Blanc’s infamous Brouillard Pillar and the rarely-attempted Bonington Route made famous by British climber Chris Bonington in 1965.

For this, and any other climb, mountaineers require lightweight but rugged technical wear that ensures easy movement while defying the elements mountainside, allowing for complete focus on the rock and ice in front of them.

Introducing the adidas TERREX Techrock Mountaineering range – worn by Laura and the Huber brothers in United By Summits as they climb one of the Alps’ most demanding routes.

Keeping climbers dry is the adidas TERREX Techrock Light Gore-Tex Mountaineering Jacket, a lightweight, packable jacket with breathable Gore-Tex Active 3-layer membrane to repel water. Adjustable hood and cuffs are compatible with helmets and gloves.

For insulation on colder climbs, the adidas TERREX Techrock Year Round Down Jacket locks in warmth with adidas-patented HeatSeal baffle construction and PrimaLoft® Gold insulation in the shoulders and cuffs. Pertex® Diamond Fuse 20 Denier yarn provides resistance to abrasion along with a water-repellent DWR-finished fabric.

For rugged, weather-resistant legwear that keeps climbers moving freely on any ascent, adidas TERREX Techrock Mountaineering Softshell Pants balance comfort and protection. Flexible, wool-backed softshell fabric moves easily while a tough nylon surface protects against abrasion. A soft waistband helps prevent bunching under harnesses for an easy-moving silhouette – essential on those long climbing days.

Kitted out in this new adidas TERREX Techrock Mountaineering range 4,000 metres above sea level, Laura and the Huber brothers achieved their goals together.

Reifenhäuser Cast Sheet Coating - specialists for cast film, sheet extrusion and extrusion coating lines - will showcase a new production process for cost-effective film/nonwoven composites with an exceptionally low grammage at ICE (International Converting Exhibition) Europe. The leading international trade show for paper, film, and foil conversion and processing will be held at Messe München (Munich trade fair center) from March 15-17, 2022.

The Covid-19 pandemic and current supply shortages have exposed the dependence of companies on global supply chains. This situation is both a warning signal and an opportunity to boost and reorganize the local production of semi-finished products from the ground up. Reifenhäuser Cast Sheet Coating has now developed a trend-setting production process termed Ultrathin Coating, in particular for the sector of medical protective clothing. The process will permit customers to produce particularly lightweight film/nonwoven composites with greater cost efficiency and, as a result, more competitively. The patent-pending process has several advantages: It cuts film grammage by 66%; material consumption in the overall composite is reduced by 28%; and it slashes costs by up to 34% compared to conventional semi-finished products. Significant cost savings are achieved in various ways, for example, by replacing hotmelt adhesives, which reduces line maintenance to a great extent at the same time.

Mark Borutta, Sales & Marketing Specialist bei Reifenhäuser Cast Sheet Coating, erklärt: „Wir erleben derzeit einen nachhaltig wachsenden Mehrbedarf für medizinische Schutzbekleidung verbunden mit einer Rückholstrategie für lokale Produktionskapazitäten. Vor diesem Hintergrund erzielen Produzenten mit ‚Ultrathin Coating‘ einen schnellen Return on Invest und hohe Profitabilität – auch bei einer Produktion innerhalb Europas.“ Die Vlies-erfahrene Schwesterfirma Reifenhäuser Reicofil –führender Hersteller von Vliesstoffanlagen – hat die Entwicklung unterstützt.

Mark Borutta, Sales & Marketing specialist at Reifenhäuser Cast Sheet Coating, explains: "We are currently experiencing a sustained increase in demand for medical protective clothing combined with a return strategy for local production capacity. Against this backdrop, producers achieve a fast return on investment and high profitability with Ultrathin Coating - even when production is based in Europe." The sister company, Reifenhäuser Reicofil, an experienced and global leading manufacturer of nonwoven lines, provided their support to the development.

Even if manufacturers already produce medical protective clothing and prefer to handle the coating process internally in the future instead of importing the necessary composites, it is worthwhile to set up an in-house production facility. In either case, the investment in Ultrathin Coating usually pays for itself in less than 12 months. The lower material input also reduces the consumption of fossil raw materials and this in turn responds to the increased demand for more sustainable products.
