• Das MMI (Materialmodellierung, mechanische Berechnung und Spritzgusssimulation)-Team für fortgeschrittene Simulationstechnologien bietet erheblich verbesserten Service für PA6-GF-Werkstoffe
• Integrative Simulationsumgebung lässt sich effektiv mit der Digimat-Software anwenden und gewährleistet präzise und robuste Finite-Elemente-Analysen

DOMOs fortschrittliche Simulationsumgebung MMI für PA66-Bauteile gilt auf dem Markt bereits als Referenz für präzise Simulationen. Ab sofort unterstützt dieses Simulationstool OEMs und Bauteillieferanten bei der Entwicklung von leistungsfähigen, leichten und kosteneffizienten Bauteilen aus PA6. Mit dem DOMO Service Hub können Bauteilentwickler ihre Polyamidlösungen somit schneller in Serie bringen.

Bei glasfaserverstärkten Materialien muss die Ausrichtung der Glasfasern berücksichtigt werden, die während des Spritzgussverfahrens entsteht. Dabei ermöglicht die Digimat-Software eine genaue integrative Simulation. DOMO besitzt ein umfangreiches Fachwissen bei der integrativen Simulation der TECHNYL® A-Serie von PA66-GF-Materialien und ist daher in der Lage, präzise Bauteilsimulationen durchzuführen.

Die neuen MMI-PA6-GF Materialkarten können für eine Vielzahl von Glasfaserkonzentrationen und -temperaturen sowie für elastische und elastoplastische Materialmodelle mit Versagensindikatoren eingesetzt werden. Diese sind in der Digimat Software verfügbar und führen zu den gleichen präzisen Ergebnissen wie bei den TECHNYL® A PA66-Werkstoffen. Die neuen Materialkarten heben somit die PA6-Datenbank auf das gleiche Leistungsniveau wie PA66 an. Im nächsten Schritt werden in die Digimat-Datenbank auch crashspezifische und thermische Modelle eingepflegt.

„Dank der präzisen MMI-Simulation können TECHNYL® Bauteile entwickelt werden, die leichter, leistungsfähiger und kosteneffizienter sind“, erklärt Gilles Robert, Material Expert bei DOMO. „Unsere Kunden profitieren von kürzeren Entwicklungszeiten und haben eine bessere Kontrolle über die internen Kosten. Der kontinuierliche Aufbau der TECHNYL®-Materialdatenbank erweitert das Anwendungsfeld dieser Simulationsumgebung auf PA6 Bauteile.“

SANITIZED AG, a specialist for hygiene function in textiles, is expanding its Sanitized® Odorex™ portfolio for odorneutralizing technologies. The new OX20 product is usable on cotton, viscose, or synthetic fibers. It does not contain any biocides, it is highly wash-resistant, and it can be combined well with other effects.

Sanitized® Odorex™ is the product of several years of experience with environmentally friendly textile treatments. SANITIZED focuses heavily on the causes of, the production of, and the fighting of unpleasant sweat odor in textiles. The basis for the newly introduced biocide-free OX20 product is a metal-free polymer that neutralizes odors. It meets market requirements regarding wash-resistance with excellent results after up to 50 household washes.

Versatile and highly cost-efficient
The new product can be applied in extraction, pad, and spray. It can be used on all common substrates and is compatible with other textile effects. These properties increase the flexibility and efficiency during product design, and they reduce production costs. As one of the first technologies worldwide, OX20 can be applied to synthetics in the dye bath.

Feel and wearing comfort
Binders and particle systems negatively affect the textile’s feel and moisture management. OX20 is a particle-free product with a long-lasting effect that does not change how the textile feels, nor does it affect the textile’s moisture management.

This month, the circular knitting machine manufacturer Mayer & Cie. is launching its upgrade kits for circular knitting machines that are already successfully in use by customers. With tailor-made packages, the company wants to give its users the opportunity to take advantage of technological progress in their existing machines. The aim is to improve the performance of the existing machines and to extend their service life. In addition to the machine-specific upgrade kits, the company now starts offering tailormade spare parts packages. They are intended to ensure machine availability and equip customers with spare parts for standard situations. In addition, they offer a degree of independence from possible failures in the supply chain and rising transport costs.

Longevity, a popular product property
“Longevity of our circular knitting machines is definitely a property that our satisfied customers mention regularly”, Mayer & Cie. sales director Wolfgang Müller says. The company estimates that up to 50 percent of all the circular knitting machines it has ever made are still around in the market somewhere.

Upgrades boost performance and value
Value retention, maintenance and upgrades for existing machines are a key issue for the company – and for the customers who successfully use existing Mayer & Cie equipment. That’s why the company recently launched customised upgrade kits to improve the long-term performance of machines.

Low budget, clear benefit
Compared to a new machine, upgrade kits are a low-cost investment that deliver clearly defined benefits. For example, an improved yarn guide ensures a significant increase in the plating reliability and output of the machine in question.

Most of the upgrade kits is machine-specific; the aforementioned yarn guide ensures a boost in productivity for the Relanit 3.2 II and Relanit 3.2 S. For S4 machines an optimised fluff blowing device can be the solution. It ensures that less fluff is knitted in and thereby improves the fabric quality. It also reduces downtimes that would otherwise be required for cleaning. Upgrade kits suitable for most Mayer & Cie. machines are the edge trimmer to open a fabric hose before the fabric’s rolling-up and the laying facility for high-quality hose fabric.

Spare part packages: Inside is what is required
In addition to individual upgrade kits Mayer & Cie. now offers spare parts packages. They too are customised for individual machines. When purchasing a machine, the customer can also order a small or a large spare parts package. Selected specially for the machine in question, it contains the most important consumables and spare parts.
The new spare parts packages also increase customers’ independence of supply chain failures and rising transport costs.

Baldwin Technology Company Inc. will showcase its latest high-performance color management, surface treatment, LED-UV curing, inspection, defect detection and Industry 4.0-based analytics solutions at Print4All, which is taking place May 3 to 6 at Fiera Milano in Italy.

One of its latest advances — which will be on display at Print4All — is the XP Quatro Series™ LED-UV curing module with one head and two frequencies for broader applications. It is designed to economically and efficiently cure LED-formulated printing inks and coatings on sheetfed and web offset printing presses, as well as on larger-format flexo presses and digital print engines. The XP Quatro Series LED-UV enhances print quality, while operating at top speeds, driving increased productivity and profitability.

Italy’s ACM Flexible Packaging selected Baldwin as its LED-UV partner and became one of the first flexible film converters to offer all LED-UV curing in a narrow to mid-web format. This partnership established LED-UV printing as a growing production standard in flexible packaging and labels. Today, ACM is a 100% LED-UV, non-mercury facility.

Baldwin’s Print4All booth also will showcase Industry 4.0 and industrial Internet of Things-enabled technologies that work together to achieve greater uptime, productivity and automation. Featured solutions pair sensor-gathered data with operational data from Baldwin equipment to gain live, actionable insights to improve production monitoring, so printers and converters can achieve new levels of color consistency with fewer defects and greater assurance of curing.

Other highlights in Baldwin’s booth include the Corona Slim treatment system, which ensures the exact dyne levels needed for perfect uniformity in application, and the Guardian PQV 100% Print Inspection, which provides complete print quality verification from prepress through production, reporting and archiving.

The Trevira CS brand will be presented at Heimtextil 2022. This year the trade fair will be held as a one-time Summer Special from 21 to 24 June in Frankfurt am Main, Germany. The booth will feature more than 200 fascinating, versatile, flame retardant Trevira CS fabrics.

These will be displayed in the Long Stay Apartment installation. Changing lifestyles, living and working arrangements as well as the housing shortage in countless large cities mean the Long Stay Apartment segment of the hospitality sector has experienced exponential growth, becoming ever more important. For this reason, it is the focus of this year’s Trevira CS booth. The presentation of the “Long Stay Apartment by Trevira CS” is intended to familiarise visitors – particularly interior architects, designers and furnishers – with the trendsetting, innovative uses of Trevira CS fabrics in the contract sector.

For the design of the apartment installation, the traditional Trevira CS Fabric Competition 2022 was announced at the end of 2021 and invited all customers to submit their latest Trevira CS products according to certain specifications. The winning fabrics will be announced at the trade fair and specially exhibited at the Trevira CS booth.

Director Marketing & Business Development Anke Vollenbröker: “Our exhibition gives exciting new insights into the modern concept of the Long Stay Apartment, presenting the live application of our customers’ Trevira CS innovations. An apartment designed for Long Stayers is a special challenge since it has to provide more than a hotel room or even an ordinary rental apartment: It needs to be an attractive temporary home while also offering the services and advantages of a hotel. We have made the Long Stay Apartment particularly “textile” and included submissions from all participants of our Trevira CS Fabric Competition 2022.”

• Turkish circular knitting market offers prospects in turbulent times

After a four-year, Covid-related break the German circular knitting machine manufacturer Mayer & Cie. is exhibiting with its Turkish representative Mayer Mümessillik (MMÜ) once more at the important International Textile Machinery Exhibition (ITM) in Istanbul. At Booth 713 in Hall 8, Mayer & Cie. will present three machines: the D4-2.2 X interlock machine, the OV 3.2 QCe for double jersey structures and the MV 4 3.2 II for single jersey fabrics. For the Mayer & Cie. and MMÜ team the focus will be on in-person contacts with customers, suppliers and partners. Despite the tense international situation both the manufacturer and its representative are positive about the medium-term outlook for the Turkish market.

Turkey is a market with prospects
“The challenges that the global economy faces are at present enormously wide-ranging, of course,” says Mayer & Cie.’s Turkey specialist Stefan Bühler. “The Russian invasion of the Ukraine, supply chain outages, shortages of raw materials and skyrocketing energy prices all create uncertainty.” And then there is galloping inflation in Turkey and elections in 2023. Yet despite, and in part because of, this state of affairs Bühler and Kahraman Güveri, CEO of Mayer & Cie.’s Turkish representative MMÜ, hold a positive view of the market outlook for the years ahead. Large orders, especially for standard products, are on the increase, Kahraman Güveri explains. That leads to new investments, new companies and a growing demand for refurbished machines that then need to be replaced by new machines elsewhere. And former commission merchants are now enterprises in their own right.

“Apart from that, Turkey benefits from its proximity to Europe, transport routes are manageable,” says Stefan Bühler. “This location advantage attracts brand manufacturers who together with their orders bring new approaches, new designs and new technologies into the country.” And Turkey’s already very highly developed textiles sector benefits too. That, says Kahraman Güveri, is why one can be confident for the next few years, “at least for as long as nothing unforeseen happens”.

Established machines with that something special: OV 3.2 QCe for double jersey structures
The portfolio of machines that Mayer & Cie. is exhibiting at the ITM is tried, trusted and popular. The OV 3.2 QCe is a specialist for interlock fabrics and double jersey structures that it knits in both filament and synthetic fibre yarns. With a conversion kit the OV 3.2 QCe also qualifies as a producer of 8-lock structures, spacer fabrics and fine gauges. The machine is available in a choice of three frames: from open-width and industrial to giant frame. Stefan Bühler, regional sales manager for Turkey, has this to say: “Not for nothing has the OV 3. 2 QCe been one of our most popular machines for years. It is mainly used for sportswear and for leisure- and outerwear.” In Istanbul the OV 3.2 QCe on show will be a 30-inch, E40-gauge model.

D4-2.2 X for fine rib and interlock fabrics
The double-jersey D4-2.2 X is an obvious choice for knitting fine rib fabrics of up to E28 gauge. Spacer and interlock fabrics are also part of the machine’s established repertoire. And it can produce elastomeric plating in both cylinder and dial cam. No matter which of these tasks is assigned to the D4-2.2 X, it performs it with impressive productivity.

MV 4 3.2 II for flexibility in the single jersey sector
In the single jersey sector, the long-established German firm delivers a literally fine solution. The MV 4 3.2 II on show at the ITM knits to an E38 gauge. The machine can also be supplied for gauges from E14 to E60. It is, in addition, highly flexible, with a repertoire that ranges from piqué and double piqué to one-thread fleece and smooth single jersey.

A new interview study from NGO ChemSec shows that there is a gap between supply and demand when it comes to recycled materials, causing confusion and bottlenecks. Among other things, suppliers go out of their way using elaborate trade schemes to reach the coveted ”100% recycled” tag, which – it turns out – is not that important to consumer product brands. Far more crucial aspects, according to several major B2C companies, are:

• Honest communication towards customers
• Comprehensive information from suppliers
• Clear standards for recycled material

These are some of the conclusions from NGO ChemSec’s survey and interview study with 26 highly well-known consumer product brands. All brands responded to a survey concerning their current plastic use, as well as their needs, expectations and challenges regarding using more recycled material, to enable the shift to a circular economy for plastics.

Ten of the brands then participated in in-depth interviews on the same topics:, Essity, H&M, IKEA, Inditex , Lego, Mars,  SC Johnson, Tarkett, Unilever and Walgreens Boots Alliance.

Is non-mechanical recycling the answer?
Only about ten percent of all discarded plastics is recycled today, which is of course not nearly enough to achieve a circular plastics economy. Despite ambitions and initiatives to reduce plastics use – replacing the materials with other, more sustainable ones – the “plastic tap” is not expected to be turned off anytime soon. Quite the opposite, which makes raising the recycling rates more important than ever.

Although commercially viable, traditional (mechanical) recycling is afflicted with severe flaws, such as legacy chemicals, quality and functionality issues, as well as the lack of clean and sorted waste streams. The brands cited quality and functionality issues as the main obstacles for using more recycled material in their products.

This opens up for non-mechanical recycling, sometimes referred to as chemical recycling, where the plastic is either dissolved or broken down into smaller building blocks. Harmful additives and other hazardous chemicals can be removed in the process, and a material comparable to virgin plastic can be achieved – at least in theory.

So far, however, non-mechanical recycling technologies are costly, energy-intensive, and often require the addition of a great deal of virgin plastic to work – the very material that needs to be phased out.

The chain of custody models needs to be detangled
Apart from these production issues, there is a wide range of chain of custody models surrounding non-mechanical recycling, including mass balance and book & claim, which enable trade of credits or certificates for recycled material.

This cuts the physical connection between input and output, making it possible for a supplier to sell a material as “100% recycled”, when the actual recycled content could be zero.

This is a major issue for the brands ChemSec has spoken to, who value honest and correct communication towards customers. It turns out, perhaps somewhat surprisingly, that being able to slap a “made from 100% recycled plastic” label on a product is not all that important to brands.

To the brands, a physical connection between input (the discarded plastic waste headed for recycling) and output (the product at least partially made from recycled plastics) is far more important.

A physical connection, along with correct and adequate information from suppliers, as well as clearer standards and guidelines than what is available today, is what brands require to increase the use of recycled material and move us closer to a circular economy for plastics.

Damit Plastikabfall reduziert wird und eine Kreislaufwirtschaft funktionieren kann, sind Mehrwegsysteme essenziell. Forschende des Fraunhofer UMSICHT und des Fraunhofer IML, die im Fraunhofer Cluster of Excellence Circular Plastics Economy CCPE zusammenarbeiten, haben für die Stiftung Initiative Mehrweg (SIM) drei kunststoffbasierte Mehrwegsysteme mit ihren Einwegalternativen verglichen. Das Ergebnis: Mehrweg ist Einweg in 14 der 17 untersuchten Kategorien überlegen und bietet großes Potenzial zum Gelingen einer Kreislaufwirtschaft. Was fehlt, sind klare politische Rahmenbedingungen und die Umsetzung der bestehenden Abfallhierarchie, die Mehrweg eigentlich priorisiert.

Nur 13 Prozent der in Deutschland produzierten Kunststoffe werden aus Rezyklaten hergestellt, im Verpackungsbereich sind es sogar nur 11 Prozent. Außerdem wird nur ein sehr geringer Teil für den ursprünglichen Zweck wiederverwendet, in der Regel dominieren Kaskadennutzungen (Downcycling). Darüber hinaus ist Deutschland einer der größten Exporteure von Plastikmüll weltweit. EU und Bundesregierung haben auf die Kunststoffproblematik reagiert: Die Produktion einiger Einwegplastikprodukte ist verboten, für PET-Getränkeflaschen wurde eine Rezyklatquote vorgeschrieben, und seit Anfang 2022 ist die Pfandpflicht für Einweggetränkeflaschen auf sämtliche Getränkearten ausgeweitet worden. »Green Deal und Taxonomie-Verordnung der EU geben die richtige Richtung für ein nachhaltiges Wirtschaften vor. Aus unserer Sicht gibt es aber folgendes Problem: Die im europäischen Abfallrecht seit Jahrzehnten geregelte Abfallhierarchie definiert eine Rangfolge bei Erzeugung und Umgang mit Kunststoffabfällen. Darin ist das Recycling der Mehrfachnutzung nachgelagert. Die Umsetzung dieser Abfallhierarchie findet bislang aber kaum statt.«, erklärt Jürgen Bertling vom Fraunhofer-Institut für Umwelt-, Sicherheits- und Energietechnik UMSICHT und Projektleiter der Studie.

Zirkularität, Performance und Nachhaltigkeit
Insbesondere für Kunststoffverpackungen existieren derzeit vorwiegend Einweglösungen. Einige Mehrwegsysteme finden sich im B2B-Bereich z. B. in der Automobilindustrie und beim Obst- und Gemüsetransport. Im B2C-Bereich sind sie eher die Ausnahme wie z. B. die Transportkisten für Lebensmittel vom regionalen Bauern. Ziel der aktuellen Studie des Fraunhofer CCPE im Auftrag der Stiftung Initiative Mehrweg war es daher, kunststoffbasierte Mehrwegverpackungssysteme zu bewerten, sie mit Einwegalternativen zu vergleichen und Empfehlungen für eine Stärkung der Kreislaufwirtschaft abzuleiten. Dazu analysierten die Forschenden die drei Mehrwegsysteme Obst- und Gemüsesteigen (bereits im Handel etabliert), Pflanzentrays (in Vorbereitung für einen großflächigen Einsatz) und Coffee-to-go-Becher (Einführungsphase). Sie wurden mit den jeweils entsprechenden Einweglösungen in den drei Bereichen Zirkularität, Performance und Nachhaltigkeit in insgesamt 17 Unterkategorien verglichen. Das Ergebnis: Mehrweg bietet für alle drei untersuchten Demonstratoren klare Vorteile – von der Materialeffizienz über geringere Kunststoffemissionen bis hin zu einem besseren Produktschutz durch robustere Ausführungen.

Mehrweg bedeutet für Unternehmen zwar zunächst einen höheren Kapitaleinsatz durch den Aufbau von Logistik und Rückfuhrsystemen, Lagerflächen und Reinigungstechnik. Langfristig erweisen sich Mehrwegsysteme jedoch als preiswerter und ressourcenschonender, sie stärken das regionale Wirtschaften und tragen zu einer erhöhten technologischen Souveränität bei. »Entscheidend für die Vorteilhaftigkeit eines Mehrwegsystems sind dabei vor allem die Umlaufzahl und die Distributionsstruktur: Je höher die Umlaufzahl und je niedriger die Transportdistanzen, desto besser schneidet Mehrweg gegenüber Einweg ab. Hier sind also dezentrale Poollösungen elementar«, erläutert Kerstin Dobers vom Fraunhofer-Institut für Materialfluss und Logistik IML, Mitautorin der Studie. Im Vergleich mit anderen Verpackungsmaterialien wie Papier oder Holz weist Kunststoff eine Vielzahl vorteilhafter Eigenschaften auf – leicht, haltbar, chemisch inert – und bleibt damit für zahlreiche Anwendungen, gerade bei Mehrwegsystemen, das Material der Wahl.

Abfallhierarchie konsequent umsetzen und Mehrweg optimieren
Dieser Bericht wendet sich gleichermaßen an Politik, Verbände, Hersteller von Kunststoffverpackungen und Anbieter von Mehrweg-Poollösungen. Das Autorenteam empfiehlt schlussfolgernd zwei zentrale Maßnahmen: Zum einen sollten Wege zur konsequenten Umsetzung der Abfallhierarchie aufgezeigt und gefördert werden. Einwegsysteme sollen erst dann zum Tragen kommen, wenn die Möglichkeiten der Mehrfachnutzung ausgeschöpft sind. »Dieses Ergebnis der Studie steht im Gegensatz zur heutigen Realität am Verpackungsmarkt. Es muss neue politische Rahmenbedingungen geben, die das Umgehen dieser Reihenfolge sanktionieren. Gleichzeitig sollten Anreizsysteme für Unternehmen geschaffen werden, um vermehrt Mehrweglösungen für Kunststoffe zu etablieren«, sagt Jürgen Bertling. Er fordert zudem eine Überprüfung der Abfallhierarchie durch ein Expertengremium und nachfolgend ihre strikte Umsetzung in der Praxis. Sinnvoll sei außerdem, weniger auf die Recyclingquoten zu schauen, sondern anspruchsvolle Rezyklatanteile in der Produktion vorzugeben.

Laut Kerstin Dobers ist die zweite zentrale Maßnahme, die vorhandenen Optimierungspotenziale für Mehrweglösungen auszuschöpfen, damit ihre Vorteile weiter ausgebaut und mögliche Defizite beseitigt werden: »Sicherlich sind auch bei den Mehrweglösungen noch zahlreiche Innovationen möglich, gerade im Online-Handel oder in der Take-away-Branche. Gute Lösungen zeichnen sich dadurch aus, dass die Verpackungen modular sind und ihr Volumen reduzierbar ist (nestbar oder klappbar). Hier sind Rahmenbedingungen für nationale und internationale Standardisierungen gefragt, um die ökologischen Potenziale der Mehrwegsysteme auszuschöpfen.« Darüber hinaus müssten Umweltkennzeichen (Label) zur Kennzeichnung von Mehrweg und Einweg eindeutig sein. Hier seien vor allem Verbände gefragt.

CALZEDONIA chooses products belonging to the GREEN LABEL line by ILUNA GROUP for its new Eco Collection of tights. They are GRS (Global Recycled Standard) and OEKO-TEX® Standard 100 certified and made with recycled yarns.

The ingredients used in the collection are:

• Q-NOVA® by Fulgar, an eco-sustainable nylon 6.6 fiber obtained from regenerated raw materials through a mechanical process that does not involve the use of chemical materials. It has been certified with the Global Recycled Standard (GRS) and for some time now has been part of the HIGG INDEX, the index developed by SAC (Sustainable Apparel Coalition) evaluating the environmental impact of the entire life cycle of a garment;
• ROICA™ EF by Asahi Kasei, one of the first recycled stretch yarns certified with Global Recycled Standard (GRS).

This collaboration confirms Iluna's commitment to creating products with a environmental responsibility thanks to a technological and corporate system that covers the entire perimeter of production, from materials to processing, dyeing and finishing. An industrial reality that increasingly integrates the value of responsibility, as demonstrated by the fact that the percentage of sustainable production has risen from 3% in 2018 to 52% in 2021.

ISKO did not miss the opportunity to be a driver for change as the community of fashion leaders gathered at the event “Drapers Sustainable Fashion 2022” on April 21st, in London. Specifically, ISKO’s presence at the event took place through a stand dedicated to the company’s commitment to the development of new processes for better industry practices, and through the participation of ISKO’s head of sustainability, Ebru Ozkucuk Guler, in the panel “Leading the way: exploring denim’s approach to responsible and sustainable manufacturing”.

The company’s technology R-TWO™50+ played a great role in showing how the innovative soul of the company matches its sustainable one. R-TWO™50+ is the driving force behind ISKO’s efforts to reduce the industry’s impact on the planet. The fabrics are made with a minimum of 50% pre- and post-consumer recycled blend that is entirely Global Recycled Standard (GRS) certified. This results in less use of natural resources and a reduced carbon and water footprint of up to 45% and 65% respectively.
Held at main Stage, the panel was a chance to delve into the great strides that the industry has taken to dramatically reduce its carbon footprint through ground-breaking technology, with the speakers stating that “sustainability strategies are essential for the health not only of the planet but also of the industry itself.”
