Truetzschler Manmade Fibres and EREMA cooperate on inline BCF systems for R-PET

After having worked successfully together during the past year, both companies have signed an agreement on the cooperation in the area of reclycled materials, especially of R-PET. The cooperation covers BCF lines which produce carpet yarns by spinning reclycled polyester or blends of virgin PET chips and recycled flakes

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

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 in 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.

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 upstream processes have little impact on the directly following spinning process, since only small pressure fluctuations occur during backwashing or screen changes.

Trützschler’s R-PET-spinning technology is based on the proven system components for spinning primary chips. The process involves theTruetzschler-EREMA R-PET Flakes and BCF bobbins well-known spin packs and the double-shell godets, the HPc-texturing system and the fully automatic winder.

Existing customers will appreciate the use of the same key components for operation of the R-PET plant. The support of process and product development for recycled polyester through process engineering in Winterthur is part of the package.

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 Fibres 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.

With about 3000 employees, Trützschler is one of the world’s leading textile machinery manufacturer. Trützschler specialises in machines, installations and accessories for spinning preparation, the nonwovens and man-made fiber industry. The headquarters of the more than 125 year old company is located in Mönchengladbach, Germany. The subsidiaries Trützschler Nonwovens & Man-Made Fiber GmbH with two production sites, and Trützschler Card Clothing GmbH, are also located in Germany. Sites in India, China, Brazil, USA and Switzerland, as well as a number of service centres, provide customer proximity in the important textile processing areas.

Since November 2012 Trützschler Switzerland AG in Winterthur is bundling decades of experience in development, design and construction of spinning lines for BCF as well as industrial yarns for technical applications as a centre of competence.
