    摘要： In a first embodiment, a hydraulically-formed nonwoven sheet, a package comprising such sheet, a method of packaging a medical device using a package with such sheet and a method of manufacturing such sheet are provided. This nonwoven sheet comprises first and second non-cellulosic polymeric fibers. The first non-cellulosic polymeric fibers have an average diameter less than about 3.5 micron, an average cut length less than about 3 millimeters and an average aspect ratio of about 400 to about 2000; the second non-cellulosic polymeric fibers have an average diameter greater than about 3.5 micron and an average aspect ratio of about 400 to about 1000. In a second embodiment, a hydraulically-formed nonwoven sheet is provided. This nonwoven sheet comprises binding material, non-cellulosic polymeric fibers and cellulosic based materials. The non-cellulosic polymeric fibers have an average diameter less than about 3.5 micron, an average cut length less than about 3 millimeters and an average aspect ratio of about 400 to about 2000. The second nonwoven sheet has a bacterial filtration efficiency of at least about 98%.

    摘要： A paperboard and a cardboard comprising at least one nonwoven web layer are provided. The nonwoven web layer comprises a plurality of first fibers, a plurality of second fibers, and a binder. The first fibers comprise a water non-dispersible synthetic polymer and have a different configuration and/or composition than the second fibers. The first fibers have a length of less than 25 millimeters and a minimum transverse dimension of less than 5 microns. The nonwoven web layer comprises at least 1 weight percent of the first fibers, at least 10 weight percent of the second fibers, and at least 1 weight percent of the binder. The paperboard and cardboard can incorporate a large amount of post consumer recycled fibers and still exhibit high strength and durability. Also disclosed is a process for producing the first fibers and the multicomponent fibers from which they are derived.
