KnitCycle: Forschungsprojekt für kreislaufgerechte Flachstrick-Textilien

87 Prozent des weltweiten Textilabfalls in der Bekleidungsindustrie landen auf Deponien oder werden verbrannt. Von den 13 Prozent, die noch mechanisch weiterverarbeitet werden, enden die meisten Alttextilien als Dämmmaterial (Downcycling). Nicht einmal ein Prozent werden zu hochwertigen Fasern aufbereitet, aus denen wieder neue Kleidung entsteht.
 
Gemeinsam mit Bache Innovative als Antragstellerin hat die Hochschule Niederrhein (HSNR) ein großes Forschungsprojekt gestartet: „KnitCycle – kreislaufgerechte Produktentwicklung für Flachstricktextilien“. Die Deutsche Bundesstiftung Umwelt (DBU) fördert das Vorhaben für zwei Jahre mit insgesamt rund 290.000 Euro, davon fließen 225.000 Euro an die HSNR.
 
Wo Textilabfall recycelt und damit in den Kreislauf zurückgeführt werden kann, muss auch weniger entsorgt werden. Werden Produktionsabfälle und -überhänge vernichtet, ist das nicht nur teuer für die Unternehmen. Für die Herstellung neuer Kleidung müssen auch wieder neue Fasern erzeugt werden. Je nach Faserstoff kommt es dabei zu großem Wasserverbrauch, starkem Pestizid- und Düngemitteleinsatz sowie langen Transportwegen mit hohen CO2-Emissionen.

Die Projektpartner erarbeiten ein Konzept, mit dem gestrickte Produkte so entwickelt werden können, dass sie sich am Produktlebensende durch ein Faser-zu-Faser-Recycling zu hochwertigen Fasern neu aufbereiten lassen. Aus diesen Fasern kann anschließend neues, industriell verarbeitbares Garn für Bekleidung hergestellt werden, das im Idealfall später abermals recycelt werden kann.
 
Unter dem Motto „Design for Recycling“ analysieren die Partner, welche Faktoren und Verfahren am besten geeignet sind, Textilien schon bei ihrer Entstehung so zu planen, dass sie am Produktlebensende optimal recyclingfähig sind. Gleichzeitig dürfen sich Ästhetik, Qualität und Langlebigkeit der Produkte nicht verschlechtern. Die Frage ist also: Welche Parameter im mechanischen Recycling werden benötigt und welche Produkteigenschaften erzielen das beste kreislauffähige Ergebnis?
 
„KnitCycle“ konzentriert sich auf Pulloverwaren und Produkte, die auf Flachstrickmaschinen endformgerecht in Deutschland produziert werden. Dafür liefert und produziert die auf 3D-Strickwaren spezialisierte Firma Bache Innovative eigenes Abfall- und Forschungsmaterial.
 
Unterstützung mit Experten-Knowhow gibt es auch von TURNS Faserkreisläufe. Dieses Unternehmen stellt recycelte Garne aus verschiedenen gebrauchten, ausrangierten Alttextilien her.
 
Die Faser-zu-Faser-Recycling-Versuche finden am hochschuleigenen Forschungsinstitut für Textil und Bekleidung (FTB) statt. Dazu schafft die HSNR von dem Fördergeld eine Reißmaschine für das Textilrecycling an. Hiermit werden vor Ort die optimalen Prozessparameter für das Recycling der jeweiligen Produkttypen ermittelt. Die in diesem Prozess gewonnenen Reißfasern werden dann u.a. mit Unterstützung der Firma Textechno H. Stein GmbH & Co. KG aus Mönchengladbach analysiert und bewertet.

Mittels unterschiedlicher Aufbereitungs- und Spinnverfahren werden aus den Reißfasern anschließend neue Garne hergestellt. Die Forschenden testen, wie sich die Fasern wiederverspinnen lassen – auch in Kombination mit anderen Naturfasern, um mit möglichst hochwertigen neuen Produkten den Produktkreislauf zu schließen.

An Labor-Strickmaschinen erzeugt das FTB-Team erste 2D-Strickproben. Die finalen Strickprodukte aus den recycelten Garnen stellt der Kooperationspartner Bache Innovative her.

EREMA presents a new solution for PET fibre-to-fibre recycling

Following their entry into the fibres and textiles sector, as announced at K 2022, recycling machine manufacturer EREMA launches the INTAREMA® FibrePro:IV - which has been specially developed for PET fibre-to-fibre recycling - at ITMA in Milan from June 8 to 14. Thanks to its especially gentle material preparation and efficient removal of spinning oils, the rPET produced can be reused in proportions of up to 100 percent for the production of very fine fibres.

Following their entry into the fibres and textiles sector, as announced at K 2022, recycling machine manufacturer EREMA launches the INTAREMA® FibrePro:IV - which has been specially developed for PET fibre-to-fibre recycling - at ITMA in Milan from June 8 to 14. Thanks to its especially gentle material preparation and efficient removal of spinning oils, the rPET produced can be reused in proportions of up to 100 percent for the production of very fine fibres.

PET is regarded as a key material for the production of synthetic fibres. Around two thirds of the total volume of PET goes into the production of PET fibres for the textile industry. This highlights the importance of high-quality recycling solutions for the circular economy. By combining proven INTAREMA® technology with a new IV optimiser, EREMA succeeds in processing shredded PET fibre materials heavily contaminated by spinning oils in such a way that the finest fibres can be produced again from the recycled pellets. The system, which now joins EREMA's machine portfolio as the INTAREMA® FibrePro:IV, is characterised by a longer residence time of the PET melt. This is an essential factor for achieving high quality recycled pellets, as it allows the spinning oils and other additives used to improve the handling of the fibres during manufacturing to be removed more efficiently than in conventional PET recycling processes. Following extrusion, by polycondensation the intrinsic viscosity (IV) of the PET melt is increased in the new IV optimiser and under high vacuum to the precise level that is needed for fibre production. "Including filtration the output quality that we achieve with this recycling process is so high that ultra-fine fibres of up to 2 dtex can be produced using these rPET pellets, with an rPET content of 100 percent," says Markus Huber-Lindinger, Managing Director at EREMA. Waste PET fibre from production processes can therefore be further processed into rPET filament fibre, carpet yarn and staple fibre.

While the focus of the fibre and textiles application is currently still on PET fibre recycling, EREMA is committed to driving forward the recycling of mixed fibre materials from classic textile recycling collection in a next project phase. In order to accelerate development work, the EREMA Group opened its own fibre test centre, where a cross-company team is working on recycling solutions for fibre-to-fibre applications. The centre also operates a fully equipped and variable industrial-scale recycling plant. It includes the peripheral technology required and is available to customers for trials.

Novafiber starts up textile recycling and airlay lines from ANDRITZ

International technology group ANDRITZ has delivered, installed, and commissioned a mechanical textile recycling line and an airlay line at Novafiber’s nonwovens production mill in Palín, Guatemala. Both lines have been successfully operating since December 2022.

The recycling line – the second tearing line ANDRITZ supplied to Novafiber – processes post-industrial textile waste from Central America. The recycled fibers feed the latest ANDRITZ Flexiloft airlay line, which produces nonwoven end-products for the bedding and furniture industries – a true example of a circular textile-to-nonwoven approach. The production process ensures complete material use as a state-of-the-art edge trim recycling system returns any waste directly to the tearing and/or airlay line.

This combination of ANDRITZ tearing and airlay lines allows Novafiber to process large amounts of post-industrial garments, controlling the supply chain from raw material to final product. In addition, it enables energy savings and a reduced carbon footprint due to the reduction of shipments.

The positive market dynamics, which Rieter has already reported on several occasions, continued in the third quarter of the current year. Rieter recorded an order intake of CHF 698.6 million in the third quarter of 2021 (2020: CHF 174.4 million).

  • Order intake of CHF 698.6 million in third quarter 2021
  • Order intake of CHF 1 673.9 million after nine months
  • Acquisition of the three Saurer businesses on schedule
  • Credit lines renewed early
  • Outlook 2021

The positive market dynamics, which Rieter has already reported on several occasions, continued in the third quarter of the current year. Rieter recorded an order intake of CHF 698.6 million in the third quarter of 2021 (2020: CHF 174.4 million).

The order intake of CHF 1 673.9 million after nine months corresponds to an increase of 294% compared to the prior year period (2020: CHF 425.1 million).
 
The market development is broadly supported at the global level and is based on a catch-up effect from 2019 and 2020 in combination with a regional shift in demand. Rieter believes that a major reason for this regional shift in demand is the development of costs in China. This is leading to increased investments outside the Chinese market. The orders came primarily from Turkey, Latin America, India, Pakistan and China. Overall, Rieter is benefitting from its innovative product range and the global positioning of the company.

The Business Group Machines & Systems achieved an order intake totaling CHF 1 281.6 million in the first nine months of 2021 (+447%).*

In the first nine months of 2021, the Business Group Components recorded an increase of 95% to CHF 227.0 million, while the Business Group After Sales posted an order intake of CHF 165.3 million, an increase of 123% compared to the prior year period.*

Acquisition of the three Saurer businesses on schedule
The acquisition of the three businesses from Saurer, which Rieter announced on August 16, 2021, is proceeding according to plan. The incoming orders for these businesses are not taken into account in this trading update.
 
Credit lines renewed early
The Rieter Group arranged the early renewal of the existing committed credit lines (five-year term, totaling CHF 250 million).
 
Outlook 2021*
The first nine months of 2021 were characterized by a rapid market recovery combined with a regional shift in demand. Rieter expects the demand for new systems to gradually return to normal in the coming months.  
 
For the full year 2021, Rieter anticipates sales of around CHF 900 million.
