  • test methods such as the Lisson test, for measuring the durability of a carpet.
  • Latex does not meet the requirements for recyclability. Processes for applying latex are energy-intensive and the associated production lines take up a lot of space. Try other forms of integration, e.g. using thermoplastics has so far failed due to the quality of the filament binding. The integration did not meet the requirements of standardized pedal, pull and abrasion loads.

It has been shown that the filaments can be adequately integrated by applying thermoplastic. A thermoplastic is applied to the underside of the top layer.

For the application of the thermoplastic, a particular shape of a slot nozzle is preferably selected, which is described further below.
