Trützschler & Erema partner on inline BCF systems for R-PET

After working together for the past one year, Trützschler and EREMA will cooperate with each other in the area of recycled materials, especially of R-PET.
“The cooperation covers BCF lines which produce carpet yarns by spinning recycled polyester or blends of virgin PET chips and recycled flakes,” Trützschler said.
Products on offer include a Vacurema basic line and secondary components from EREMA which feed the inline connected Symttex spin positions of Trützschler, with a high-quality polymer melt.
According to Trützschler, for cost reasons, recovered secondary raw materials, such as flakes from used PET bottles, have long been a popular commodity in both the plastic and the fibre industry.
“Since the quality of the raw material plays a decisive role when spinning thermoplastic polymers, the bottle flakes have to be treated with special care,” the German textile machinery maker said.
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,” the company added.
“The upstream processes have little impact on the directly following spinning process, since only small pressure fluctuations occur during backwashing or screen changes,” it observed.
Trützschler's R-PET-spinning technology is based on the proven system components for spinning primary chips, which involves spin packs and double-shell godets, HPC-texturing system and the fully automatic winder. (AR)
