Bottle flakes instead of rPET chips

 

VarioFil R+ reduces the spinning process, as one-step PET has become the primary material for beverage packaging, and billions of PET bottles are used worldwide each year. The 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+ underscores 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. Downstream with Oerlikon Barmag’s eAFK texturing machine improves yarn quality.

 

Further open house attractions were the live presentation of the texturizing process, converting the manufactured rPOY into DTY on Oerlikon Barmag’s eAFK texturizing machine, as well as BBE’s new cleaning system for melt filters, known as White Filter Cleaning (WFC). WFC allows the cleaning of melt filters, but also of other melt-contaminated parts without any chemical solvents and is a good complementary system for the VarioFil R+ line to clean its filtration equipment.

 

Other activities

 

A virtual tour through the new VarioFil R+ line as well as insights into the winder assembly department of Oerlikon Barmag, the originator of the famous WINGS POY winder, and several technical presentations covering the fields of recycling, yarn production from recycled feedstock and dope-dyeing all made the open house an informative day for participants.

 

BB Engineering is a joint venture between Oerlikon Manmade Fibers/Oerlikon Barmag and Brueckner Group, both based in Germany. BBE provides extrusion equipment such as extruders and melt filtration systems and the VarioFil turnkey spinning lines for the flexible production of POY, FDY and IDY yarns.

REMSCHEID, Germany – More than 120 customers from around the world attended BB Engineering GmbH’s (BBE) open house event on January 21, where the company unveiled a new machine. Visitors saw the world’s first “VarioFil R+” bottle-to-POY line in operation, producing 150f48 dope-dyed black yarn.

 

The new VarioFil R+ is the world’s first POY spinning line that uses recycled bottle flakes as feedstock for dope-dyed textile POY, according to the company. The line – developed by BBE, a subsidiary of Oerlikon Barmag – 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, two-step melt filtration. The result is a high quality dope-dyed POY.

 

The turnkey machine comprises four spinning positions, each equipped with an Oerlikon Barmag 10-end WINGS® POY winder.
