Definitions

  • melt blowing process is currently the most common technique of producing fine fibers. Due to the constructional design, this process has so far been limited to fiber sizes of more than 2 ⁇ m. In this process, a low-viscosity medium is used which is torn apart at the attempt to achieve lower fiber thicknesses.
  • EP 0 674 035 A2 discloses a spinning beam in which air is supplied from the side.
