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.

EREMA: Circular economy for PET fibres

The textile industry is the third largest consumer of plastics. While growth rates in the production of fibres and textiles are high, the circular economy has hardly become established in this segment. The EREMA Group is now intensifying development of recycling solutions for this application with their new fibres and textiles business unit. Currently, the focus is on PET fibre materials from fibre production and subsequent processing steps. Technologies for recycling mixed fibre textiles from textile collection sources are to follow in a follow-up project phase.

The textile industry is the third largest consumer of plastics. While growth rates in the production of fibres and textiles are high, the circular economy has hardly become established in this segment.

Currently, the focus is on PET fibre materials from fibre production and subsequent processing steps. Technologies for recycling mixed fibre textiles from textile collection sources are to follow in a follow-up project phase.

"With EREMA's VACUREMA® and INTAREMA® technology and PURE LOOP's ISEC evo technology, our company group already has an extensive range of machines for fibre and PET recycling applications. For ecologically and economically sound recycling, however, new technological solutions are needed to use the recycled fibres in higher-value end applications and to achieve a functioning circular economy," explains Wolfgang Hermann, Business Development Manager Application Fibres & Textiles, EREMA Group GmbH. The initial focus will be on PET, regarded as a key material for the production of synthetic fibres. The aim is to find recycling solutions that allow PET fibre materials to be prepared for reuse in PET fibre production processes. This is a significant step for the circular economy because PET fibres in textiles account for about two-thirds of the total volume of PET.

In this development work, the EREMA Group can build on existing know-how. Proven recycling technologies have been combined with a new IV optimiser. "This extends the residence time of the PET melt, which is particularly necessary in fibre recycling to efficiently remove spinning oils. Our recycling process also increases the IV value of the PET melt after extrusion back to the specific level that is essential for production of the fibre," explains Hermann. Waste PET fibre from production processes can therefore be further processed into rPET filament fibre, carpet yarn and staple fibre.

Fibre test centre with plant to test customers' materials
In order to accelerate development work, EREMA opened its own fibre test centre a few months ago, where a cross-company team is working on recycling solutions for fibre-to-fibre applications.

Inhomogene Textilabfälle zu neuen hochwertigen Produkten machen

  • DITF beteiligt sich am internationalen Konsortium zum Kunststoffrecycling ‚WhiteCycle‘

Ein Konsortium aus 16 öffentlichen und privatwirtschaftlichen Organisationen hat sich unter dem Namen ‚WhiteCycle‘ zusammengeschlossen, um ein umfassendes und geschlossenes Recyclingsystem für Plastikabfälle zu etablieren. Die Deutschen Institute für Textil- und Faserforschung Denkendorf (DITF) werden als Teil des Konsortiums ihren Beitrag mit einem neuen Syntheseverfahren zur Verarbeitung von recycelten Kunststoffen leisten.

Unter Leitung der Michelin Group Frankreich konstituierte sich das Konsortium ‚WhiteCycle‘ Anfang Juli 2022. Ziel der europäischen Initiative ist es, einen Wirtschaftskreislauf zu etablieren, um inhomogene Textilabfälle aus verschiedenen Materialien aufzubereiten und daraus neue, hochwertige Produkte herzustellen. Dieses Vorhaben soll dazu beitragen, die von der Europäischen Union gesteckten Ziele bei der Reduktion von CO2-Emissionen bis zum Jahr 2030 zu erreichen.

Dieses Vorhaben soll dazu beitragen, die von der Europäischen Union gesteckten Ziele bei der Reduktion von CO2-Emissionen bis zum Jahr 2030 zu erreichen.

Komplex aufgebaute, textilhaltige PET-Abfälle wie Reifen, Schläuche oder mehrlagige Verbundtextilien aus dem Bekleidungsbereich sind bisher schwer oder gar nicht recycelbar. Unter dem WhiteCycle-Netzwerk werden mehrere Projekte und Forschungsansätze zusammengeführt, die sich des Problems annehmen und neue Lösungsansätze liefern sollen.

Die DITF werden ein bestehendes PET-Syntheseverfahren an neuartige recycelte Monomere anpassen. Das zu bewältigende Problem besteht in den Verunreinigungen im Ausgangsmaterial, die durch dessen inhomogene Zusammensetzung bedingt sind.

Zusammen mit dem Projektpartner Kordsa Teknik Textil A.S. (Türkei) entwickeln die DITF neue Syntheserezepte. Sie haben zum Ziel, mögliche Nachteile abzustellen, die durch verbleibende Verunreinigung der Monomere zustande kommen. Denn trotz einer Reinigung der Monomere vor deren Weiterverarbeitung können nicht alle Verunreinigungen entfernt werden. Die Ansätze, die dabei verfolgt werden, sind anspruchsvoll. So müssen Art und Menge der verwendeten Zusatzstoffe spezifisch angepasst werden. Dazu gehören Katalysatoren, Verarbeitungshilfsmittel, Nukleierungs- und Kupplungsmittel sowie Kettenverlängerer. Auf diese Weise ist es möglich, die negativen Auswirkungen von unbekannten Verunreinigungen zu vermeiden. Damit verbessern sich die Materialeigenschaften der wiederverwerteten Kunststoffe, da sie langfristig thermisch stabilisiert werden, was wiederum in einer Verbesserung der mechanischen und rheologischen Eigenschaften resultiert. Das modifizierte Verfahren soll es ermöglichen, dass recyceltes PET (r-PET) die gleichen Eigenschaften wie virgin PET aufweist.

Die Konsortialpartner verfolgen andere Ansätze, um eine verbesserte Recyclingrate und hochwertigere r-PET-Produkte zu erzeugen: Optimierte Sortiertechnologien für die sortenreine Trennung von Abfällen gehören ebenso dazu wie eine enzymbasierte Behandlung von Kunststoffen, um sie auf nachhaltigem Weg in Monomere aufzuspalten. Letztlich wird auch die hochqualitative Fertigung neuer Produkte aus den recycelten Kunststoffen dazu beitragen, den Rohstoffkreislauf zu schließen.

Kelheim Fibres at Dornbirn GFC WEBINAR WEEK

  • Circular economy at Kelheim Fibres: Examples of innovation from raw material, product design and all the way to “end of life”

Kelheim Fibres, the world's first viscose fibre manufacturer with an EMAS-certified environmental management system, is continuously working on optimising its special fibres. These can be functionalised as needed - in many cases to save further processing steps (such as dyeing or coating) and thus energy, water and chemicals - and are completely biodegradable at the end of their product life in a short time (according to OECD Test 301 B).

Currently, the specialists in Kelheim are working on the development of alternative raw materials for the production of viscose fibres, such as recycled cellulose as well as other cellulose-containing starting materials. One approach to closing the product cycle in the textile sector is the use of pulp produced from recycled post-consumer waste materials.
