Remscheid, Shanghai, October 21, 2016 – Oerlikon Barmag will be informing visitors to this year’s international trade fair ITMA Asia and CITME 2016 between October 21 and 25 at the new National Exhibition Center China (NECC) in hall 2, booth A16 in Shanghai about latest develop-ments in the field of recycling solutions for spinning.
The VarioFil R+ is the world’s first POY spinning line which uses recycled bottle flakes as feedstock for dope-dyed textile POY. The line provides several technological features such as a special extrusion system for bottle flake materials, the latest metering and blending technology for dope-dyeing and an advanced 2-step melt filtration. The result is a high quality dope-dyed POY. The turnkey machine comprises 4 spinning positions, each equipped with an Oerlikon Barmag 10-end WINGS POY winder.
Bottle flakes instead of rPET chips: VarioFil R+ reduces spinning process for one step
PET has become the primary material for beverage packaging, billions of PET bottles are used worldwide each year. This huge quantity of PET bottles, usually disposed as waste after initial use, is a perfect source of raw material for the sustainable production of synthetic fibers. Furthermore, the reutilization of resources and raw materials, along with energy saving production processes, are becoming increasingly popular. The VarioFil R+ concept combines all these trends. It uses PET bottle flakes as a raw material, which avoids the additional pelletizing of bottle flakes into rPET chips. This leads to a significant advantage in terms of investment and energy costs. It also provides the latest technology for dope-dyeing, which is the most resource-saving dyeing process. Hence, the development of VarioFil R+ underlines the trend of increasing demand for textiles made from yarns which have a ‘sustainable background’. It also provides the possibility for recycling companies to sell high-quality yarns instead of bottle flakes, therefore generating added value.
