Definitions

  • the invention relates to a device for producing spunbonded nonwovens from continuous filaments, in particular from continuous filaments made of thermoplastic, with a spinnerette for spinning the filaments, a cooling device for cooling the spun filaments and a drawing device for drawing the filaments, and wherein between the cooling device and the Stretching device an intermediate channel is arranged.
  • endless filaments differ from staple fibers, which have much shorter lengths of, for example, 10 mm to 60 mm because of their virtually endless length.
  • EP1340843 A1 discloses a spunbond device for producing spunbond nonwovens.
  • the filaments relax and snap back, forming a tangle that, due to the molten state of the Fil noirs stuck together.
  • the resulting defects in the spunbonded fabric usually have sizes smaller than 2x2 mm. As a rule, however, they can be felt and / or seen. Such defects occur particularly at higher throughputs from 120 km / h / m and in particular at throughputs from 150 kg / h / m. Even greater depths of the spinning field favor irregularities in the spunbonded fabrics. - Attempts have already been made to reduce these problems by making the filament treatment more uniform. In particular, attempts have been made to reduce the defects in the spunbonded fabric by more uniform cooling in the cooling device. However, especially with high throughputs, these measures have only led to limited success. There is therefore a need for improvement.
