Recycling PET fiber back to PET fiber

Intarema FibrePro:IV (photo) has been developed for fiber-to-fiber recycling of polyethylene terephthalate (PET). 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% for the production of very fine fibers. By combining proven Intarema technology with a new IV optimizer, the process succeeds in processing shredded PET fiber materials heavily contaminated by spinning oils in such a way that the finest fibers can be produced again from the recycled pellets. The system is characterized by a longer residence time of the PET melt — essential for achieving high-quality recycled pellets. — Erema Group, Ansfelden, Austria
