Erste konkrete Ergebnisse ausgewählter Projekte präsentiert BIOTEXFUTURE auf den Gemeinschaftsstand Bioökonomie des BMBF auf der Hannover Messe (22. bis 26.4.2024) sowie auf der fast zeitgleich stattfindenden Internationalen Leitmesse für technische Textilien und Vliesstoffe, Techtextil, in Frankfurt / Main (23. bis 26.4.2024). Folgende Projekte werden vorgestellt:

  • BioTurf: der Kunstrasen der Zukunft ist grün (Hannover Messe / Techtextil)
  • CO2Tex: innovative elastische Garne binden CO2 (Hannover Messe / Techtextil)
  • DegraTex: biologisch abbaubare Geotextilien (Techtextil)
  • BioBase: Textilien für Innenräume, Sport, Auto und Technik werden bio (Hannover Messe / Techtextil)

BioTurf: der Kunstrasen der Zukunft ist grün
Die Forscher*innen des Projekts BioTurf arbeiten an der Lösung eines Problems, mit dem hunderte von Städten und Gemeinden konfrontiert sind. Ziel ist es, eine Kunstrasenstruktur aus Bio-Polyethylen (PE) zu entwickeln, das sich qualitativ nicht von erdölbasiertem PE unterscheidet. Diese Monomaterial-Struktur soll ein hochwertiges Materialrecycling ermöglichen. Eine wichtige Basis für die spätere Kreislaufführung des Produktes. Darüber hinaus wird die neuartige Kunstrasenstruktur ohne die Zugabe von Einstreu-Granulat auskommen und damit das aktuelle Mikroplastik-Problem von Kunstrasenplätzen lösen. Es existiert bereits ein BioTurf-Fußballplatz in Aachen als Demonstrationsspielfeld, auf denen Sportler*innen spielen und trainieren, und dadurch die Forscher*innen regelmäßig Rückmeldung bekommen. Man befindet sich in der Phase der Feinjustierung, um das Ziel zu erreichen den Kunstrasen der Zukunft aus 100% biobasiertem Polyethylen herstellen zu können.

CO2Tex: innovative elastische Garne binden CO2
Die Textilwissenschaftler*innen des BIOTEXFUTURE Projekts CO2Tex entwickeln elastische Filament-Garne, in deren Ausgangsmaterial das für die Erderwärmung mitverantwortliche Treibhausgas CO2 gebunden ist. Gleichzeitig verwenden sie für die Garnherstellung Schmelzspinnprozesse, für die keine giftigen und umweltschädlichen Lösungsmittel notwendig sind. Den Forscher*innen ist es zudem gelungen, die Elastizität der auf thermoplastischen Polyurethanen (TPU) beruhenden Entwicklung für bestimmte Garntypen an das Leistungsvermögen der konventionellen Elastane heranzuschrauben. Das Projekt-Konsortium erwartet, dass für die entwickelten CO2-haltigen elastischen TPU-Filament-Garne eine Hochskalierung der Produktionsprozesse auf eine massentaugliche Fertigung im Industriemaßstab in absehbarer Zeit möglich sein wird. Dabei hält das CO2Tex-Team vergleichbare Herstellungskosten wie bei konventionellen Garnen sowie leichte Vorteile bei der Energiebilanz gegenüber bestehenden Prozessen für möglich.

DegraTex: biologisch abbaubare Geotextilien
Das Ziel von DegraTex ist die Entwicklung biobasierter, abbaubarer Geotextilien für kurzfristige Anwendungen wie die zeitlich begrenzte Sicherung von Erdstrukturen oder für den Vegetationsschutz. Die Materialien erfüllen ihre Funktion, bis sie von natürlichen Komponenten, wie z.B. bodenstabilisierenden oder bodendeckenden Pflanzen, übernommen werden oder simpel einfach nicht mehr benötigt werden. Es geht darum, konventionelle, erdölbasierte Geotextilien in technisch und ökologisch sinnvollem Rahmen durch biobasierte und abbaubare Produktlösungen zu ersetzen. Das Forschungsteam des ITA hat bereits erste Demonstratoren auf Basis von Biopolymeren im Außeneinsatz.

BioBase: Textilien für Innenräume, Sport, Auto und Technik werden bio
Im BioBase-Projekt wird die gesamte textile Wertschöpfungskette der jeweiligen Produkte abgebildet und in jedem Prozessschritt der technologische Reifegrad für die industrielle Produktion von biobasierten und nachhaltigen Chemiefasern schrittweise erhöht. Zunächst entstehen hierbei in Kooperation zwischen den Forschungseinrichtungen und Industriepartner*innen industriell gefertigte Anschauungsmodelle (Demonstratoren), die das Potenzial der am Markt verfügbaren biobasierten Polymere demonstrieren sollen. Die Herstellung der Polymere, Garne und textilen Flächen, orientiert sich sehr anwendungsbezogen an den existierenden technischen Anforderungen in den unterschiedlichen Industrie-Sektoren.
Das Team in Aachen beschäftigt sich mit der Herstellung von Chemiefasergarnen und betrachtet dabei die Arbeitsschritte Schmelzspinnen und Texturieren der Wertschöpfungskette und teilweise auch die Flächenherstellung. Die Forschungen zeigen, dass biobasierte Polymere existieren, die auf bestehenden Anlagen entlang der textilen Prozesskette bis zum Demonstrator verarbeitbar sind, wobei die Garn- und Textileigenschaften je nach Anforderungsprofil angepasst werden können.

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 subject of the master's thesis was the development of a mechanism with which faulty sections in the weft yarn can be sorted out before they are woven into the textile. This way, both yarn-related weft defects and material defects can be drastically reduced. The prototype developed by Mr Zerbes shows how this can be done even during the ongoing weaving process without having to stop production. Due to its modular design, the yarn rejection unit can be retrofitted to many different types of air-jet weaving machines, which represents an enormous savings potential not only in Germany but in weaving mills all over the world.

Tape inserts offer big potential for injection molding parts

Market and technology analysis confirms big potential for tape inserts in the injection molding process. Following the finalization of a major consortial project led by the Aachen Center for Integrative Lightweight Production (AZL) and the Institute for Plastics Processing at RWTH Aachen University (IKV), the result is clear: tape inserts offer enormous potential for injection molding parts. For suitable components, product costs and component properties can be positively influenced.

In cooperation with 20 industrial partners, the two renowned Aachen research institutes AZL and IKV carried out a detailed analysis of tape inserts in injection molded components over a period of eight months. The tapes, which are a few tenths of a millimeter thick, are continuous fibers, typically made of glass or carbon, completely impregnated and embedded in a thermoplastic matrix. The tapes can be precisely aligned to the loads in a component and are used primarily in high-performance applications with the aim of weight reduction. The aim of the conducted analysis was the identification of potential applications and the estimation of a wider range of applications.

The tapes can be precisely aligned to the loads in a component and are used primarily in high-performance applications with the aim of weight reduction. The aim of the conducted analysis was the identification of potential applications and the estimation of a wider range of applications.

The project was divided into several phases: Phase I was used to identify the current status. In 20 interviews with representative companies of the injection molding industry, the researchers gathered why tape inserts have rarely been taken into account so far, when defining the material concepts to be analyzed. The lack of information about the material class, the procedure and tools for the development process and the necessary production technologies were cited as major challenges. This is where the consortium will take action and provide comprehensive information during the “Technology Information Day” on the extensively prepared state of the art and the high degree of maturity of the supply chain. Based on the status quo, they developed a methodology for analyzing the technological and economic potential of tape inserts in injection molding applications.

Both the previous results and the planned follow-up projects are the subject of the “Technology Information Day" at K 2019, to which the companies involved in the study, the AZL and IKV, invite all companies along the value chain, from raw material manufacturers to injection molders to OEMs. (Date: 18th October 2019, 10:00 am to 1:30 pm, Trade Fair Düsseldorf CCD South, Room 002).

The consortium, amongst others consisting of Asahi Kasei Europe GmbH, BASF SE, Borealis AG, BÜFA Thermoplastic Composites GmbH & Co. KG, ENGEL AUSTRIA GmbH, Huesker Synthetic GmbH, LG Hausys R&D Center, Mitsui Chemicals, Nippon Electric Glass, Polyscope Polymers BV, POLYTEC GROUP, Simcon kunststofftechnische Software GmbH, SABIC and Toray International Europe GmbH, is inviting to the “Technology Information Day” at K 2019. The goal is to inform about the technology and to identify topics for future collaboration.

The exhibits come from various fields of application and address the automotive, aerospace and mechanical engineering sectors.

  1. Innovative glass fibre research at ITA
    The newly constructed induction heated glass fibre production line enables increased flexibility in research. For the first time, glass fibres will be produced live at the ITA booth at JEC World. One of the innovations of the system is the inductively heated bushing. It features a flexible design and consists of a platinum/rhodium alloy (Pt/Rh20) for use in high-temperature glasses.
    The glass fibre production line was designed in such a way that new concepts and ideas can be tested quickly. The modular design allows a high flexibility, the induction system a significantly faster operability.
    Research and development projects can therefore be carried out faster and more cost-effectively.
     
  2. DrapeCube - Forming of textile semi-finished products
    The DrapeCube offers a cost-effective design for the production of fibre preforms from textile semi-finished products. It is used in the production of preforms for prototypes and in small series and is suit-able for companies active in the production of fibre-reinforced plas-tics (FRP).
    In the production of FRP components, the preforming process de-fines a large part of the subsequent component costs. In small- and medium-sized enterprises, this process step is often still carried out manually. This results in high quality fluctuations and component prices. Especially in the case of highly stressed structural components, the fluctuation in quality leads to oversizing of the components.
    Thus, the lightweight construction potential of fiber-reinforced plastics is underused. One solution is offered by the stamp forming process adapted from the sheet metal forming industry for shaping rein-forcing textiles. The textile is inserted between two mould halves (male and female) and automatically formed. Due to high plant and tooling costs, this process is used almost exclusively in large-scale production.
    The ITA has developed the DrapeCube forming station which offers a cost-effective alternative and is able to completely reproduce the current state of the art for forming textile half branches. The process steps will be demonstrated in a video at the booth.
     
  3. Carbon fibre reinforced plastic (CFRP) preform
    The CFRP preform consists of carbon multiaxial fabrics formed by expanded polystyrene (EPS) to optimise draping quality. Preforms of increased quality can be produced by gentle, textile-compatible forming with foam expansion. For the first time, foam expansion was used to form preforms in such a way that the draping quality is improved compared to classic stamp forming.
    The advantages of the CFRP preform lie in the savings in plant costs, as the investment is much lower. In addition, the proportion of waste is reduced because near-net-shape production is possible. In addition, rejects are reduced, as fewer faults occur in the textile.
     
  4. Embroidered preform with integrated metal insert
    The 12k carbon fibre rovings are shaped into a preform using Tai-lored Fibre Placement (TFP) which is a technical embroidery pro-cess. For the further layer build-up, a fastener is not only integrated under the roving layers but also fixed by additional loops. The highly integrative preforming approach offers the possibility of reducing weight and process steps as well as increasing mechanical perfor-mance.
    Until now, inserts were glued or holes had to be drilled in the com-ponent. Bonded fasteners are limited by the adhesive surface. The bonding of fasteners into drilled holes results in high drill abrasion and thus high tool wear.
    The advantages of the embroidered preform with integrated metal fasteners are the reduction of scrap due to TFP preforming and the increase in the specific pull-out force. In addition, it is possible to automatize the production of integrative preforms. This makes the preform with integrated metal fasteners interesting for the automotive and aerospace industries.

Die Exponate stammen aus unterschiedlichen Anwendungsfeldern und adressieren die Branchen Automotive, Luft- und Raumfahrt und Maschinenbau.

  1. Innovative Glasfaserforschung am ITA
    Der modulare Aufbau der neu entwickelten, induktiv beheizten Glasfaserproduktionsanlage ermöglicht hohe Flexibilität in der Forschung und das Induktionssystem eine deutlich schnellere Bedienbarkeit. Erstmalig werden am Stand des ITA Glasfasern live auf der JEC World hergestellt. Zu den Neuheiten der Anlage gehört das induktiv beheizte Bushing. Es hat ein flexibles Design und besteht aus einer Platin-/Rhodium-Legierung (Pt/Rh20) zum Einsatz für Hochtemperaturgläser. Die Glasfaserproduktionsanlage wurde so konstruiert, dass sich neue Konzepte und Ideen schnell erproben lassen.
     
  2. DrapeCube – Umformung textiler Halbzeuge
    Der DrapeCube bietet eine kostengünstige Konstruktion zur Herstellung von Faservorformlingen aus textilen Halbzeugen. Er kommt zum Tragen bei der Fertigung von Preforms für Prototypen und in der Kleinserie und eignet sich für Unternehmen, die in der von faserverstärkten Kunststoffen (FVK) tätig sind.
    Bei der Produktion von FVK-Bauteilen wird im Preformingprozess ein Großteil der späteren Bauteilkosten definiert. In kleinen und mittelständischen Unternehmen wird dieser Prozessschritt oft noch manuell ausgeführt. Daraus resultieren hohe Qualitätsschwankungen und Bauteilpreise. Besonders bei hochbelasteten Strukturbauteilen führt die Qualitätsschwankung dazu, dass die Bauteile überdimensioniert sind. So wird das Leichtbaupotential von faserverstärkten Kunststoffen zu wenig genutzt.
    Eine Lösung bietet das aus der blechumformende Industrie adaptierte Stempelumformverfahren zur Formgebung von Verstärkungstextilien. Dabei wird das Textil zwischen zwei Formhälften (Patrize und Matrize) eingelegt und automatisiert umgeformt. Dieses Verfahren kommt aufgrund hoher Anlagen- und Werkzeugkosten fast ausschließlich in der Großserie zum Einsatz. Das ITA hat die Formgebungsstation DrapeCube entwickelt, die eine kostengünstige Alternative bietet und in der Lage ist, den aktuellen Stand der Technik für die Formgebung textiler Halbzeige vollständig abzubilden. Am Stand werden die Prozessschritte in einem Video demonstriert.
     
  3. Kohlenstoffaserverstärkter Kunststoff (CFK)-Preform
    Der CFK-Preform besteht aus Carbon-Multiaxial-Gelege, das durch expandiertes Polystyrol (EPS) umgeformt ist, um die Drapierqualität zu optimieren. Durch die schonende, textilgerechte Umformung mittels Schaumexpansion können Preforms in erhöhter Qualität hergestellt werden. Erstmalig wurde die Schaumexpansion genutzt, um Preforms so umzuformen, dass die Drapierqualität im Vergleich zur klassischen Stempelumformung verbessert wird.
    Die Vorteile des so umgeformten CFK-Preforms liegen in der Einsparung von Anlagenkosten, da das Investment viel geringer ist. Dazu wird der Verschnittanteil reduziert, weil eine endkonturnahe Fertigung ermöglicht wird. Darüber hinaus wird der Ausschuß verringert, da weniger Fehler im Textil entstehen.
    Zielgruppe sind die Hersteller von faserverstärkten Bauteilen, insbesondere für die Klein- und Mittelserie, bei denen die klassische Stempelumformung nicht wirtschaftlich ist.
     
  4. Gestickter Preform mit integriertem Metallinsert
    Die 12k Carbonfaserrovings werden durch das Spezial-Stickverfahren Tailored Fibre Placement (TFP) zu einem Preform abgelegt. Beim weiteren Lagenaufbau wird der Insert nicht nur unter den Rovinglagen integriert, sondern durch zusätzliches Umschlaufen fixiert. Der hochintegrative Preformingansatz bietet die Möglichkeit zur Reduktion von Gewicht und Prozessschritten sowie zur Steigerung der mechanischen Performance.
    Bisher wurden Inserts geklebt oder es waren Bohrungen im Bauteil notwendig. Aufgeklebte Inserts sind durch die Klebefläche limitiert. Das Einkleben von Inserts in Bohrungen zieht hohe Bohrerabrasion und damit hohen Werkzeugverschleiß nach sich.
    Die Vorteile des gestickten Preforms mit integriertem Metallinsert bestehen in der Reduktion von Verschnitt durch TFP-Preforming und der Steigerung der spezifischen Ausreißkraft. Dazu besteht die Möglichkeit, die Herstellung integrativer Preforms zu automatisieren. Damit ist der Preform mit integriertem Metallinsert interessant für die Zielgruppe Automotive und Luft- und Raumfahrt.

ITA at the Composites Europe 2018 in Stuttgart

At the Composites Europe in Stuttgart /06 - 08 November 2018), the Institut für Textiltechnik of RWTH Aachen University, short ITA, will be showing products, components and machines along the fibre composite process chain. The ITA will present itself at the booth of the Aachen Center for Integrative Lightweight Construction (AZL) in hall 9, booth E70. Various demonstrators will be used to present selected innovative processes and products over the individual steps. The exhibits come from different fields of application: From mobility applications to the construction sector. Here is an example from the field of "construction composites":

With the concrete bar stool with hybrid carbon reinforcement, the ITA demonstrates that textiles as reinforcement structures for concrete elements allow a enormous geometrical freedom of Design. So far, manual positioning of the textile reinforcement used to be time-consuming and complex, as permitted tolerances are in the millimetre range. Thus the production mainly contributed to the high costs of textile concrete.

Thus the production mainly contributed to the high costs of textile concrete.

At the ITA, the two industrial partners Albani Group GmbH & Co. KG and DuraPact 2.0 Kompetenzzentrum Faserbeton GmbH developed a new hybrid reinforcement with integrated spacer. This hybrid reinforcement reduces the time required to position the reinforcement by up to 60 percent and thus makes the material significantly more

The new, cost-effective hybrid reinforcement contains an integrated spacer and thus faciliates the positioning of dry and coated reinforcements. The integrated spacer allows several layers of reinforcement to be stacked quickly, allowing the desired degree of reinforcement to be set. The hybrid reinforcement consists of a carbon or glass fibre grid joined with a permeable polyamide mat and will be available in roll form from industrial partners in the near future.

ITA auf der Composites Europe 2018 in Stuttgart

Das Institut für Textiltechnik der RWTH Aachen University, kurz ITA, zeigt auf der Composites Europe in Stuttgart vom 06.-08. November Produkte, Bauteile und Maschinen entlang der Faserverbundprozesskette. Das ITA präsentiert sich auf dem Stand des Aachener Zentrums für integrativen Leichtbau (AZL) in Halle 9, Stand E70. Anhand verschiedener Demonstratoren werden ausgewählte innovative Prozesse und Produkte über die einzelnen Schritte hin dargestellt. Die Exponate stammen aus unterschiedlichen Anwendungsfeldern: Von Mobilitätsanwendungen bis hin zur Baubranche. Anbei ein Beispiel aus dem Baubereich:

Durch den Barhocker aus Beton mit hybrider Carbon-Textilbewehrung beweist das ITA, dass Textilbetonelemente eine enorme geometrische Gestaltungsfreiheit ermöglichen und gleichzeitig einfach herstellbar sind. Bislang war die manuelle Positionierung der Textilbewehrung zeitaufwändig und komplex, da zulässige Toleranzen im Millimeterbereich liegen. So trug die Fertigung hauptsächlich zu den hohen Kosten von Textilbeton bei.

Am ITA wurde gemeinsam mit den beiden Industriepartnern Albani Group GmbH & Co. KG und DuraPact 2.0 Kompetenzzentrum Faserbeton GmbH eine neue Hybridbewehrung mit integriertem Ab-standshalter entwickelt. Diese Hybridbewehrung senkt die erforderliche Zeit zur Positionierung der Bewehrung um bis zu 60 Prozent und macht den Werkstoff damit deutlich wettbewerbsfähiger.

Die kostengünstige, hybride Bewehrung enthält einen integrierten Abstandshalter und ermöglicht damit die einfache Positionierung von trockenen und beschichteten Bewehrungen. Durch den integrierten Abstandhalter lassen sich schnell mehrere Bewehrungslagen stapeln, wodurch der gewünschte Bewehrungsgrad einstellbar ist. Die Hybridbewehrung besteht aus einem Carbon- oder Glasfasergitter, das mit einer durchlässigen Matte aus Polyamid gefügt ist und in naher Zukunft bei den Industriepartnern als Rollenware erhältlich ist.
