  • Wet-laid nonwoven mat and a process for making same
    Patent number: 6365001
    Abstract: A method for making a nonwoven reinforcing may for vinyl floor coverings is described. A base mat is formed from a mixture of glass fibers and polymeric binder fibers and/or powder, follows by treatment with a second water-based polymeric binder composition. The mat has been found to be highly satisfactory as a substrate for compressible vinyl floor covering.
    Type: Grant
    Filed: May 25, 2001
    Date of Patent: April 2, 2002
    Assignee: Owens Corning Fiberglas Technology, Inc.
    Inventors: Gregory S. Helwig, Hendrik Jongetjes, Paul Geel

  • Reinforced plastics carrier for printed circuits
    Patent number: 3937865
    Abstract: Non-woven glass-fiber webs for reinforcing plastics material carrying printed circuits are produced by the wet process from E-glass fibers bonded with polyvinyl alcohol. The polyvinyl alcohol used is a powder or suspension, has a degree of hydrolization of 98 - 100%, and a viscosity, as a 4% solution in water of 20.degree.C, of 20-100 cP. Preferably the polyvinyl alcohol has a degree of swelling at 20.degree.C of between 3 and 8, and in the dry form a particle size of between 50 and 180 .mu.. A plurality of these glass fiber webs are impregnated with a solution of an epoxy resin, arranged as a laminate, then compressed at elevated pressure and temperature to form the final laminate.
