Trützschler And EREMA Cooperate To Supply Inline BCF Systems Using R-PET

After working together for over a year, Trützschler and EREMA have signed an agreement to cooperate in the area of recycling, especially on R-PET. The cooperation includes BCF lines to produce carpet yarns through melt spinning of recycled polyester or blends of virgin PET chips and recycled flakes.

The products offered includes a VACUREMA Basic Line and secondary components from EREMA which feed the connected symTTex spin positions of Trützschler Man-Made Fibers with a high-quality polymer melt to produce BCF Yarns.

Recycling of PET has gained momentum for environmental reasons as well as for cost reasons and recovered secondary raw material, such as PET bottle flakes, has been a popular commodity in both the plastic and in the fiber industry. EREMA’s VACUREMA technology offers modular solutions with a vacuum reactor, a directly connected single-screw extruder and a high-performance filter for this process step. The high quality of the melt with respect to viscosity (IV value) and purity lays the foundation for top-quality filaments through Trützschler’s R-PET spinning technology based on proven system components for spinning primary chips for years. The process involves well-known spin packs and the double-shell godets, the HPc-texturing system and the fully automatic winder.

Last year, Trützschler and EREMA jointly developed a carpet yarn plant for BCF yarns from recycled PET on customer demand. While the reactor, the extruder and the polymer filters were delivered by EREMA, Trützschler Man-Made Fibers was responsible for spinning, drafting and winding. The plant is very flexible, so that both yarns from 100% recycled material or blends with PET primary granules can be spun. The BCF yarns are used for various applications.
