Abstract

Die Erfindung betrifft die Herstellung von flüssigkeitsabweisenden Mikrofaservliesstoffen unter Zusatz einer hydrophobierenden, oberflächenaktiven Substanz, kurz OAS, mittels des Schmelzblasverfahrens.The invention relates to the production of liquid repellants Microfiber nonwovens with the addition of a hydrophobic, surface-active Substance, OAS for short, using the meltblowing process.

Bei erfindungsgemäß hergestellten Mikrofaservliesstoffen, liegen die OAS zwangsläufig an der Oberfläche, da der mittlere Faserdurchmesser der Fasermatrix (1) dem mittleren Durchmesser der als Füllstoffpartikel (2) einbrachten OAS angepasst ist; Der mittlere Faserdurchmesser der Fasermatrix (1) ist geringer, als der mittlere Durchmesser der Füllstoffpartikel (2).The OAS are in microfiber nonwovens produced according to the invention inevitably on the surface because the average fiber diameter of the fiber matrix (1) the average diameter of the OAS introduced as filler particles (2) is adapted; The average fiber diameter of the fiber matrix (1) is less than the average diameter of the filler particles (2).
