Patent number: 6730393Abstract: A polymeric sheet having excellent cut-resistance contains: (A) a polymeric material, and (B) a hard filler distributed in the polymeric material, the hard filler having a Mohs hardness value of at least about 3.0, the hard filler being in the form of particles having an average diameter sufficient to provide cut-resistance properties to the polymeric material but which is no more than about 5 microns. The cut-resistant sheet may be in the form of a conventional sheet, a film, a coating, a composite and the like, and may be used to form cut-resistance articles such as, e.g., protective garments and tires. The cut-resistant sheet may also be laminated onto a textile fabric to form a composite from which articles, e.g., garments, can be formed.Type: GrantFiled: October 8, 1997Date of Patent: May 4, 2004Assignee: Honeywell International, Inc.Inventors: Ehteridge Odell Oakley, Gregory J. Johnson, Herman Leslie Lanieve

Patent number: 6242094Abstract: An antistatic bicomponent fiber comprises a nonconductive first component made of a first polymer and a conductive second component made of a second polymer containing a conductive material, where the second polymer has a lower melting point than the first polymer. The bicomponent fiber is made by co-extruding the two polymers at a temperature above their melting points, stretching the extruded fiber to increase the tensile strength, and heat treating the fiber at a temperature between the melting point of the first polymer and the melting point of the second polymer to improve the conductivity of the conductive second component. The bicomponent fiber is preferably a sheath/core fiber.Type: GrantFiled: May 8, 1998Date of Patent: June 5, 2001Assignee: Arteva North America S.A.R.L.Inventors: Robert Anthony Breznak, Joseph Andrew Foldhazy, Robert Allen Ritchie, Herman Leslie LaNieve, III, Wolfgang Alfred Piesczek
