From the Sector

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.

BB Engineering has been shortlisted for the Plastics Recycling Awards Europe 2022 for the category Recycling Machinery Innovation with its PET recycling line VacuFil® Visco+ for fiber-to-fiber inline recycling.

The process presented as part of the award is the combined VacuFil® Visco+ with VarioFil®. This machinery enables the textile industry to perform closed-loop inline recycling of post-consumer polyester (PET) textile waste. The given recycling technology is a thermo-mechanical recycling process optimized for the textile industry. Key component here is the liquid state polycondensation reactor, known as Visco+, to adjust the intrinsic viscosity. Compared to existing fiber recycling processes, which address rather less demanding textile applications and don’t include subsequent spinning, BBE’s solution is a whole-in-one process that enables the textile industry to perform closed-loop inline recycling of post-consumer PET fiber waste even into high-tech textile yarns with low dpf-values.

The Plastics Recycling Awards Europe 2022 winners will be announced on 23 June, during the second day of the Plastics Recycling Show Europe taking place at the RAI Amsterdam.
