NICHTGEWEBTER NASSPRESSFILZ UND VERFAHREN ZU SEINER HERSTELLUNG.

摘要

A papermaker's wet press felt constructed entirely from a plurality of layers of non-woven batt fibers (20, 22, 24, 26) which have layers of polymeric mesh (12, 14, 16, 18) interposed between and alternating with the batt layers. The mesh layers may be a thermoplastic material having a lower melt temperature than the batt fibers. The mesh layers and batt layers may be fixed by needling, sewing, heating or some combination thereof.
