VacuFil/VarioFil R+ BB Engineering has offered its VacuFil PET recycling system and its VarioFil R+ synthetic fiber-spinning lines as independent systems. VacuFil dries and plasticizes bottle flakes, agglomerated spinning waste or a combination of the two, then filters and degasses the melt. It can turn the melt into PET granulate, or directly feed downstream processes. The VarioFil R+ turnkey system extrudes resin, then filters the melt and feeds the yarn through radial airflow to cool the fibers and then collect them with either a winder or take-up unit. The VarioFil R+ is available in configurations to handle a variety of materials. The company planned to host an open house during K show at its facility in Remscheid, Germany, where it would demonstrate the two systems operating together, with the melt from VacuFil directly feeding the spinning process of the VariFil R+.

What’s new? The use of 100 percent PET textile waste. BB Engineering conducted trials with 100 percent post-consumer PET cloth and has now validated this capability. 

Benefits Wider range of potential material sources. Customers can look to a single supplier for the entire turnkey system. And the VacuFil system’s filter has a large surface area that removes contaminants without affecting throughput, while its in-line viscosity measuring unit allows it to continuously adjust the intrinsic viscosity of the resin to deal with inconsistencies caused by different material inputs.
