TREATED NONWOVEN FABRICS AND METHOD OF TREATING NONWOVEN FABRICS

The present invention provides a method of treating a nonwoven fabric to provide the fabric with repellency to fluids while minimizing impact to the hydrostatic head properties of the fabric. Generally, the process includes contacting a nonwoven fabric with an aqueous treatment solution that include...

Beschreibung
Zusammenfassung:	The present invention provides a method of treating a nonwoven fabric to provide the fabric with repellency to fluids while minimizing impact to the hydrostatic head properties of the fabric. Generally, the process includes contacting a nonwoven fabric with an aqueous treatment solution that includes a fluoropolymer and a polymeric antistatic agent. La présente invention concerne un procédé de traitement d'un non-tissé pour conférer à l'étoffe une résistance au mouillage par des fluides tout en minimisant l'impact sur les propriétés de charge hydrostatique de l'étoffe. D'une façon générale, le procédé comprend la mise en contact d'un non-tissé avec une solution aqueuse de traitement qui comprend un polymère fluoré et un agent antistatique polymérique.
