Particulates in nanofiber webs

The present invention is directed to a method of forming nonwoven webs comprising particulates. The method of forming the nonwoven web generally comprising the steps of forming fibers from a melt fibrillation process, forming at least one fluid stream containing particulates, mixing said fibers with...

Beschreibung
Zusammenfassung:	The present invention is directed to a method of forming nonwoven webs comprising particulates. The method of forming the nonwoven web generally comprising the steps of forming fibers from a melt fibrillation process, forming at least one fluid stream containing particulates, mixing said fibers with said particulates to form a fiber-particulate mix, and depositing the mix on a surface to form a web. The nonwoven web will have the particulates entrapped in the web. The nonwoven web may comprise a layer having a significant number of nanofibers with diameters less than one micron.
