From the Sector

Die langjährige strategische Kooperation des Thüringischen Instituts für Textil- und Kunststoff-Forschung Rudolstadt e.V. (TITK) mit der Technischen Universität Ilmenau erreicht einen neuen Meilenstein: Beide Partner nahmen jetzt eine Anlage zur Herstellung thermoplastischer Leichtbauplatten in Betrieb. Damit wurde eine moderne gerätetechnische Voraussetzung geschaffen, um die Zusammenarbeit zwischen dem an der TU ansässigen Thüringer Innovationszentrum Mobilität (ThIMo) und dem TITK insbesondere im Kompetenzfeld Kunststofftechnik und Leichtbau zu erweitern.

Die Investition wird aus Mitteln des Landes Thüringen und der EU im Rahmen der Grundfinanzierung des Thüringer Innovationszentrums Mobilität (ThIMo) gefördert. In Abstimmung zwischen dem TITK und dem ThIMo und auf Grundlage eines Nutzungs- und Überlassungsvertrages wurde die Anlage im Technikum des TITK aufgestellt. Das TITK ist seit vielen Jahren An-Institut der TU Ilmenau.

„Um unsere wissenschaftliche Zusammenarbeit voranzutreiben, läuft derzeit auch die gemeinsame Berufung der Professur Kunststofftechnik an der TU“, berichtet der geschäftsführende Direktor des TITK, Benjamin Redlingshöfer. „Damit festigen wir unsere Kooperation zwischen Grundlagenforschung auf der einen und wirtschaftsnaher Forschung auf der anderen Seite“, ergänzt der vorläufige Leiter der Uni, Prof. Dr. Kai-Uwe Sattler.

Beiden Teilbereichen der Forschung soll nun auch die neue Plattenanlage dienen. Sie kommt gemeinsamen Entwicklungsprojekten im Bereich kunststoffbasierter Halbzeuge und parallel dazu der Ausbildung von Studenten zugute. „Mit dieser Anlage wurde eine weitere Voraussetzung geschaffen, um auch den Transfer gemeinsamer Forschungsergebnisse in die Wirtschaft zu forcieren“ “, betont Prof. Dr. Klaus Augsburg, Projektleiter ThIMo an der TU Ilmenau. „Diese neu geschaffene wissenschaftlich-experimentelle Plattform ist mit unserem Technikum Kunststofftechnik passfähig“, so Augsburg weiter.

„Mit der Plattenanlage stellen wir Halbzeuge mit Faserverstärkung her, etwa aus Naturfaser-, Glasfaser- oder Carbonfaserverstärktem Kunststoff. Die Platten sollen insbesondere für Leichtbauanwendungen in verschiedenen Mobilitätssystemen zur Verfügung stehen“, sagt die zuständige Abteilungsleiterin am TITK, Dr. Renate Lützkendorf. Je nach Beschaffenheit des Ausgangsstoffs seien dabei auch Verbunde mit verschiedenen Schichten möglich.

Als Ausgangsmaterialien kommen sowohl marktverfügbare Kunststoffgranulate als auch Neuentwicklungen zum Einsatz. Darunter ein mit Partnern entwickeltes Granulat aus recycelten Carbonfasern. Speziell mit diesem Material lässt sich einerseits eine sehr hohe Steifigkeit erreichen. „Andererseits kann damit auch das Thema Leitfähigkeit oder Abschirmung erschlossen werden. So lassen sich Platten mit funktionellen Eigenschaften produzieren“, ergänzt Lützkendorf.

Erforscht werden zudem komplette Prozesse zur Herstellung neuer Faserverbundhalbzeuge. Dabei stehen verschiedene Aspekte im Mittelpunkt. „Zum Beispiel die Auswirkung von Füllstoffen auf die Plattenqualität und ihre Funktion, die Dicken, mit der diese Halbzeuge herstellbar sind, und ob sich die Platten auch schäumen lassen, um noch weiteres Gewicht einzusparen“, erläutert Dr. Thomas Reußmann, stellvertretender Abteilungsleiter am TITK.

Neben einer wesentlichen Zielgruppe beider Partner, der Automobilindustrie, können auch Themen anderer Branchen, wie z.B. der Verpackungsmittelindustrie bedient werden. Die Entwicklungsergebnisse werden durch Materialprüfungen am TITK und am ThiMo evaluiert.

With the PFAFF 4520, engineers and technicians from PFAFF have designed a full-automatic production line (CE compliant) for processing multi-layer disposable masks, which meets the requirements of "German engineering" in a unique way. The product combines 150 years of expertise in joining textile materials and a concentrated know-how of the PFAFF INDUSTRIAL and KSL brands in the areas of process control, automation and robotics.

The PFAFF 4520 is an investment in a robust and sophisticated production line (MADE IN GERMANY) with an exceptionally reliable working process. In times of Covid-19 it is so important to rely on the right equipment for the mask production and avoid costly readjustments or an unnecessary second investment!

Key facts of the unit:

-    Size of the mask: 175 x 95 mm
-    Output:  3,500 – 4,000 masks per hour
-    1-, 2- or 3 ply processing  (Non-woven/filtration fabric)
-    SPS (PLC) control of the entire mask system
-    Exceedingly quiet working process of the whole unit
-    Ultrasonic welding components from German manufacturers
-    Protective housing for occupational safety of the operator
-    Packing station + printing station for personalized masks (on request)

The machine package also includes important features in the pre- and after sales:

PFAFF technicians ensure the adjustment of the desired customer material (non-woven or similar filter material) and the number of layers (1-, 2-, 3-ply) to the machine and make a "Ready to production" installation of the whole unit at the customer.  A fast service response time in after-sales (by involvement of the PFAFF sales- and service partner on site) ensures a maximum production output.

Elastics for power support in medicine and the work environment
People who do physically hard work are relieved; people who are learning how to walk again after an accident or a stroke receive support; people with a handicap gain greater mobility – exoskeletons offer valuable support in many areas. An important component for "power suits": elastics by JUMBO-Textil.

Support construction with and without drive
An exoskeleton is a kind of robot that you wear: a construction of mainly textile components that is slipped over the body and strapped on. Integrated sensors register the body movements. These impulses are converted into electrically driven movements of the exoskeleton, which support or amplify the human movement. In addition, exoskeletons without drive are also being developed: these designs aim to transfer the weight of heavy tools or loads directly into the ground.

Tough requirements, individual solutions
Since the skeletons are worn on the body, the textiles and textile components used here need to be skin-friendly and as light as possible. The body's own temperature regulating systems must not be impeded. The contact surfaces must not create pressure points. And the exoskeletons must be individually adaptable to the user's body measurements.

High-tech elastics by JUMBO-Textil offer solutions for the development of exoskeletons – in terms of functionality, safety and wearing comfort: they hold, clamp, close and secure. They relieve and cushion movements and force impact. They illuminate and forward signals. The breathable narrow textiles stretch in both directions as required. They fit snugly on the body and follow every movement. Full-surface hook-and-loop-ready elastic tapes offer a simple, secure and individually adjustable fastening option. JUMBO-Textil consistently uses components made of plastic or light metal for textile components as fastening solutions. As a solution partner for demanding tasks – e.g., in occupational safety – JUMBO-Textil also developes cooled or heated textiles in collaboration with their customers. Also possible: the development of self-luminous narrow textiles – for additional safety.

Elastics für die Kraftunterstützung in Medizin und Arbeitswelt
Menschen, die körperlich schwer arbeiten, werden entlastet; Menschen, die nach einem Unfall oder Schlaganfall wieder zu gehen trainieren, erhalten Support; Menschen mit Handicap gewinnen größere Mobilität – Exoskelette bieten in vielen Bereichen wertvolle Unterstützung. Wichtiges Bauteil für die „Kraft-Anzüge“: Elastics von JUMBO-Textil.

Unterstützungskonstruktion mit und ohne Antrieb
Ein Exoskelett ist eine Art Roboter zum Anziehen: eine Konstruktion aus vorwiegend textilen Komponenten, die über den Körper gestreift und angeschnallt wird. Integrierte Sensoren registrieren die Körperbewegungen. Diese Impulse werden in elektrisch angetriebene Bewegungen des Exoskeletts umgewandelt, die die menschliche Bewegung unterstützen oder verstärken. Daneben werden auch Exoskelette ohne Antrieb entwickelt: Diese Konstruktionen zielen darauf ab, Gewicht von schweren Werkzeugen oder Lasten direkt in den Boden abzuleiten.

Hohe Anforderungen, individuelle Lösungen
Da die Skelette am Körper getragen werden, müssen die verbauten Textilien und textilen Bauteile hautfreundlich und so leicht wie möglich sein. Die körpereigene Temperaturregulation darf nicht behindert werden. Die Auflageflächen dürfen keine Druckstellen erzeugen. Und die Exoskelette müssen sich individuell an die Körpermaße der Nutzer*innen anpassen (lassen).

Hightech-Elastics von JUMBO-Textil bieten Lösungen für die Entwicklung von Exoskeletten – in puncto Funktionalität, Sicherheit und Tragekomfort: Sie halten, spannen, schließen und sichern. Sie entlasten und dämpfen Bewegungen und Krafteinwirkungen. Sie leuchten und leiten Signale weiter. Die atmungsaktiven Schmaltextilien sind je nach Bedarf in beide Richtungen dehnbar. Sie schmiegen sich eng an den Körper an und machen jede Bewegung mit. Vollflächig klettfähige Elastikbänder bieten eine einfache, sichere und individuell anpassbare Befestigungsmöglichkeit. Für textile Bauteile als Befestigungslösung nutzt JUMBO-Textil konsequent Komponenten aus Kunststoff oder Leichtmetall. Als Lösungspartner für anspruchsvolle Aufgaben – z. B. im Arbeitsschutz – entwickelt JUMBO-Textil ¬mit seinen Kunden gern auch gekühlte oder beheizte Textilien. Ebenso möglich: die Entwicklung selbstleuchtender Schmaltextilien – für zusätzliche Sicherheit.

Baldwin Technology Company Inc. will be offering two virtual opportunities for customers to learn more about the company’s innovative non-contact spray finishing systems. These technologies will be showcased in October during an in-depth webinar event, as well as during the Innovate Textile and Apparel Virtual Trade Show.

The interactive and free webinar “How to Deliver Sustainability with Non-Contact Spray” will be held twice on October 13, with a recording provided for all who register for later viewing. During this event, industry veteran Rick Stanford, Baldwin’s Business Development Leader for textiles, will discuss the sustainable functionality of the Precision Spray and Ahlbrandt Rotor Spray technologies.

The Innovate Textile and Apparel Virtual Trade Show will take place online October 15 to 30. In Baldwin’s virtual booth, the company will showcase its non-contact spray systems for finishing and remoistening. Its TexCoat G4, TexMoister G2 and Ahlbrandt Rotor Spray technologies are designed to save chemistry, time and production costs, while enabling sustainable textile production.

“We are excited to present our revolutionary non-contact spray systems during the webinar and the virtual Innovate Textile and Apparel show,” said Stanford. “Participants will learn how non-contact spray has become a game-changing technology in sustainable textile finishing. It dramatically cuts chemical waste and energy consumption, while increasing productivity and quality. We will show attendees how our systems work and in what applications they are ideal for, as well as take questions. These are great opportunities to experience innovations that drastically improve both the process and product quality, while saving time and chemistry, and contributing to a more sustainable future.”

• Fabric finishing and sanforization systems installed in the US and Turkey to enhance productivity

ST. LOUIS - Baldwin Technology Company Inc. has successfully installed six new fabric finishing and sanforizing precision spray systems in the US and Turkey. Despite the COVID-19 pandemic, the installations were completed in just 60 days, thanks to close collaboration between onsite Baldwin textile team members, local agents and remote support from the company’s product and technology center in Sweden.
For textiles, non-wovens and technical textiles, Baldwin’s precision spray technology processes a wide range of low-viscosity water-based chemicals, such as softeners, anti-microbial agents, water repellents, oil  repellents, flame retardants and more.

These systems enable fabric producers to significantly reduce chemical and water consumption, while speeding up production times and eliminating production steps, including drying and bath changeovers when switching fabric colors. “Our customers are major manufacturers in fabric dying, finishing and remoistening, and we want to provide outstanding service and support—even in times like this,” said Rick Stanford, Business Development Leader at Baldwin and the commercial leader of the US installations. “Not only does our precision spray technology enhance productivity in their process, but there is also zero waste, which goes hand-in-hand with the increased sustainability focus in the textile industry.”

In North Carolina, two new TexCoat G4 precision spray systems are now in production with major international vertical manufacturers of outdoor living, performance fabrics and automotive fabrics. In Georgia, a major vertical manufacturer of workwear and protective fabrics installed a sanfor precision spray system, which has helped the customer obtain deeper penetration of moisture into fabrics treated with durable water repellents. In Turkey, three new TexCoat G4 systems were installed in Çorlu, northwest of Istanbul, for a large producer of knit fabrics, such as T-shirts. “In Turkey, the manufacturer purchased and installed one TexCoat G4 system before COVID-19, and the customer was so pleased with the results that, during the pandemic, three more were purchased,” said Simone Morellini, Sales Manager- EMEAR at Baldwin and the commercial leader of the Turkish installations. “The systems were manufactured and installed during the lockdown, and now, all four systems are up and running, and being used heavily on a daily basis.” “With the success we have seen, we plan to apply the same strategies for upcoming installations, including the next one in Honduras: strong local management and customer coordination, combined with  effective remote support during the installation,” said Stanford.

• Gorilla Protect is a new company formed in May this year to promote the Catus face mask – a major leap forward in the effectiveness of personal protection products that are available to consumers in the fight against Covid-19.
• Behind Catus and the new company is Nova Textil, the established fabric finishing company based in Grefrath, Germany, and now run by father and son team Rainer and Oliver Hurtz.

Single stenter

Rainer Hurtz founded Nova Textil with a single Monforts Montex stenter and just five employees in 1999 and has steered its constant development and growth over the past twenty years.

“Our initial focus was on the coating of mainly glass fibre fabrics, awnings and sun protection products for outdoor furnishings,” he said. “We had a great customer who was providing us with so many orders that by 2005 we took the decision to order a second Montex stenter, in a special configuration. This also allowed us to enter the market for blackout and digital printing fabrics. We’ve had a great ongoing relationship with Monforts from the beginning.”

A third Montex stenter line was installed at the company’s Grefrath plant in 2015, by which time the company had grown to 40 people and a major new market had opened up in the supply of fabrics for promotional materials at exhibitions and trade shows.

“We had a fantastic two years in 2018 and 2019 and everything was going great for the first three months of this year, but in April it all came crashing down,” said Oliver Hurtz. “Coronavirus put an end to trade shows in 2020, which had a very serious impact on our business.”

At the same time, however, the company was exploring the potential of a new biocidal product from one of its chemicals suppliers which has both antiviral and antimicrobial properties.

Filtration

“We had already been producing coated fabrics for hot gas filtration and realised that in combination with this new microporous coating we had the basis for a very effective single-layer face mask,” Rainer said. “Achieving this with a single layer product rather than the usual three has resulted in a significant advance in comfort for the wearer and because the mask is able to disinfect itself and helps regulate humidity, it can be worn a number of times without needing to be washed, for greater convenience. It only needs to be washed when it gets dirty and can also be washed up to twenty times without losing its properties, which has to be preferable to single-use disposables.”

Catus face masks are based on 100% woven cotton and the active ingredients in the finish are a reaction mass of titanium dioxide and silver chloride certified to ISO 20743 for their antibacterial effect, and to ISO 18184 for their antiviral effect.

They are proven to  eliminate over  99.99% of the human coronavirus 229 E, with the multiplication of microorganisms such as germs and bacteria prevented by the biostatic action of silver salts and viruses destroyed by oxygen-releasing substances and a mechanism that attacks their fatty envelope. The virus membrane loses its cholesterol content and the virus is inactivated.

Colours

Gorilla Protect next plans to make the masks available in four colours – black, Bordeaux, olive and grey – and is also working on colour branding and printing labels.

“It’s not possible to print on the surface of the mask after it has been coated, but its is possible for volume orders to be printed before the treatment,” Oliver Hurtz said.

“Face masks are going to become an established part of life in the West like they are in Asia and need to be as comfortable and convenient as possible for the wearer,” his father concluded. “With these things in mind, we believe Catus is a significant step forward.”

New blade edge and integrity sensors save operators time and money

Paper Converting Machine Company (PCMC), part of Barry-Wehmiller, has announced that the Xcut saw, its newest tissue saw, now includes innovative sensors that monitor saw blade condition. This new technology tracks the edge of the blade and monitors it for the earliest indications of a blade crash.

The blade edge sensor monitors the current diameter of the blade, and automatically adjusts functions like grinder depth and other blade wear compensations. This sensor also gathers data that can be used to study the blade wear rate. Using a blade diameter measurement, which is performed in real time, along with the number of cuts and grind parameters, the PLC can fit a regression function to this data to inform the operator of the estimated number of cuts remaining on the blade for a given product diameter. Understanding blade wear allows operators to more easily optimize the process and preplan for blade changes.

In addition, the Xcut saw features a fiber optic blade integrity sensor. A blade with a chip or portion of the edge missing will produce cuts with streaks or shreds that are unacceptable to most producers. The defect is usually detected only after a significant amount of product is cut and potentially passed on to the packaging operations. The material expense, lost production and time it takes to purge the product from the system are costly. During normal operation, the sensor is covered by the blade. If at any point the sensor becomes uncovered, it puts the saw into emergency stop mode. The sensor would only become uncovered if the blade crashes or breaks. The emergency stop prevents further damage to the saw caused by slinging blade fragments.

“The blade edge technologies, along with the many other innovations on the Xcut, make the saw easier to maintain and safer to operate,” said Jonathon Zahn, PCMC’s Lead Mechanical Engineer for the Xcut. “Ease of use and operator safety are always goals when developing new products at PCMC.”

• Epson DG-Tinten und Pre-treatments von der Ecocert-Group für den Einsatz in einem GOTS-zertifizierten Textilproduktionsprozess zugelassen
• Epson UltraChrome DG- und reaktive Genesta-Tinten GOTS anerkannt

Kunden und Markenhersteller legen hohen Wert auf nachhaltige, umweltverträgliche Produktions- und Lieferketten. Daher sehen sich die Produzenten von textilen Materialien zunehmend der Forderung gegenüber, die ökologische Verträglichkeit ihrer Produktionsketten nachzuweisen. Epson unterstützt Hersteller bei diesem Ziel. So wurden seine UltraChrome DG-Tinten und Pre-Treatments, die beispielsweise in den SureColor SC-F3000 und dem SC-F2100 (beide DTG-Druck) verwendet werden, für den Einsatz in einem GOTS-zertifizierten Textilproduktionsprozess zugelassen. Auch die reaktiven Genesta-Tinten, welche für die industriellen Textildrucker der Monna-Lisa Reihe entwickelt wurden, empfingen diese Bestätigung.

GOTS ist der führende Textilverarbeitungsstandard für organische Fasern. Ziel des Standards ist es, Bedingungen zu definieren, welche die Nachhaltigkeit der textilen Grundstoffe von der Ernte der Rohstoffe bis hin zur Nutzung belegen. Das bietet dem Endkunden Sicherheit bei der Auswahl der Produkte, denn das Siegel des GOTS-Standards für Stoffe und Kleidungsstücke wird in allen wichtigen Märkten akzeptiert.

Frank Schenk, Head of Commercial & Industrial Printing der Epson Deutschland GmbH, erklärt: „Nachhaltiges Wirtschaften liegt in der DNA von Epson. In dieser Hinsicht ist es für uns wichtig, unsere Kunden beim Aufbau einer ökologisch verträglichen Produktionskette zu unterstützen. Die Bestätigung, dass sowohl unsere DG- als auch reaktive Genesta-Tinten für den Einsatz in einem GOTS-Textilproduktion Prozess zugelassen wurden, unterstreicht dies eindrucksvoll.“

For more than 50 years, vehicle manufacturers have relied within their model development on Autoneum’s measuring systems for vehicle acoustics. With ATLAS, Autoneum has now added another particularly powerful device to the portfolio: Thanks to the efficient and reliable measurement methodology, noise-reducing vehicle components and materials can be analyzed and developed faster and with a significantly lower need for resources in the future.

With the ongoing electrification of vehicles and trends like autonomous driving, future car generations will no longer be used solely for transport – remote working and recreation will equally play a key role. This requires a vehicle interior that is as noiseless as possible. In order to identify and insulate potential internal and external sound sources already in the pre-development of new models, car manufacturers around the world rely on Autoneum’s highly specialized measurement tools. The newly launched ATLAS – short for “Airborne Transmission Loss Analysis System” – measures the acoustic insulation and transmission loss of components such as carpets, inner dashes and floor insulators. This allows customers to assess noise-reducing parts within minutes and select acoustic components tailored to their needs.

ATLAS sets new testing standards in this regard. While developers previously had to analyze the NVH behavior (noise, vibration, harshness) of interior parts using material samples of around one square meter in size, ATLAS makes this process faster, cheaper and more environmentally-friendly. It enables measurements of small samples with a diameter of no more than ten centimeters, which substantially decreases the amount of material used. Thanks to its four highly sensitive microphones, only two trials are required to collect precise and valid test data, making the system developed at Autoneum’s research center in the Swiss city of Winterthur especially suitable for quality assurance and repeatability of the results obtained. Users also benefit from time savings of up to 50 percent compared to the previous testing standard.

Autoneum’s measurement systems represent the global industry standard and are used successfully by vehicle manufacturers, automotive suppliers and research institutions alike. The Company is therefore not only making a significant contribution to the mobility of the future with its noise-reducing products, but now with ATLAS as well.
