Technical Yarn

Technical Yarn

Typical applications are e.g.:
Tire cord, HMLS, Safety belts, Ultra-fine mono filaments, Ropes, Carpet, yarns, BC, Yarns for reinforcement for technical rubber articles like straps and conveyor belts

  • Typical materials: PET, PA 6, PA 66, PP, PE
  • Common throughputs up to 1.500 kg/h
  • Filtration finenesses down to 10 µm

In the manufacturing of technical yarns, ultra-fine filtration is used not only for the removal of solid inhomogeneities, but also to retain or to destroy gel-like contamination. In some cases, very high spinning temperatures are encountered, making a very short dwell time of the melt necessary. High throughput rates make a fully-automatic mode of operation of the filtration system without any influence on the process essential. The RSFgenius was developed especially for these requirements and makes continuous cost reduction in the manufacturing process with top product qualities possible.

The advantages of Rotary Filtration

  • Constant pressure = constant temperature in the spinpack = constant product properties
    Thanks to the process-constant mode of operation of the RSFgenius as the pre-filter, the temperature in the spinpack can be kept constant, so that variations of product properties are avoided.
  • Consistent material properties thanks to a short dwell time of the melt
    Thermal degradation of the melt is avoided, the viscosity remains constant. In this aspect, the RSFgenius is substantially different from conventional candle or disk filters.
  • Longer spinpack life time
    The fully-automatic mode of operation of the RSFgenius avoids any influence on the spinning process all year. Pre-filtration with < 20 µm directly upstream of the spinpack is possible, so that the spinpack can be used primarily for melt homogenization.
  • Higher melt purity, reduction of filament breaks and fluff
    A higher melt purity improves the spinpack specifications and therefore leads to a more homogeneous melt quality and to a constant melt flow.
  • Simple and safe screen changes
    Danger to the operators and environment during filter changes is eliminated. Thanks to the encapsulated design of the RSFgenius any influence from air during the filtration process is avoided.
  • Maximum line availability
    Screen changes without any production interruptions and disturbances as well as the fully-automatic mode of operation of the RSFgenius with integrated self-cleaning make a maximum line availability possible.
