New fibrous textiles for the air filtration market

Objectif

The aim of the FILAIRCO project was to develop new ultra-fine fibres, with a diameter of less than a micron, thanks to the possibilities offered by the two-component extrusion-spinning process. These fibres are intended for the development of new nonwoven media for air filtration.

Expertises

  • Prototyping of durable liquid filters (performance and service life) on its pilot lines of nonwoven melt-way by the two-component Meltblown process.
  • Criteria for the selection of polymer couples to be combined in two-component extrusion-spinning (physical and rheological properties).
  • Development of two-component fibres allowing access to utlrafine fibres (extrusion-spinning process).
  • Development and prototyping of nonwovens carded from these two-component fibres.
  • Development of two-component spunbond nonwovens and meltblown nonwovens with ultra-fine filaments.
