Patent number: 5935879Abstract: The present invention is a non-woven fiber mat suitable for reinforcing resilient sheet floor coverings, such as vinyl floor coverings. The non-woven fiber mat is in the form of a sheet of reinforcement fibers which at least includes semi-coiled fibers and can also include coiled fiber, with one or more turns, and even some relatively straight or slightly curved fibers. It is desirable for most, if not all, of the reinforcement fibers to be made from glass. However, it may also be desirable for the reinforcement fibers to include glass fibers and synthetic fibers. It may even be possible for the reinforcement fibers to include only non-glass fibers. At least one polymeric binder is used for bonding together the reinforcement fibers so as to make the fiber mat a suitable substrate for reinforcing resilient sheet floor coverings, such as an interlayer for vinyl floor coverings.Type: GrantFiled: March 20, 1996Date of Patent: August 10, 1999Assignee: Owens Corning Fiberglas Technology, Inc.Inventors: Gregory S. Helwig, W. Scott Miller, Kimberley A. Householder

Patent number: 5885908Abstract: An anisotropic elastic web, particularly an anisotropic elastic film layer having a machine direction and a cross direction and having a thickness of from 20 to 300 microns formed of an extruded blend of a block copolymer elastomer portion and a polyolefin polymer portion blended in a ratio of from 10:1 to 0.4:1, respectively. The elastomer portion generally is a block copolymer elastomer formed of A blocks and B blocks, the A blocks are formed predominately of monoalkenyl arene and the B blocks are formed predominately of conjugated diene. The polyolefin portion is comprised predominately of an inelastic fiber forming polyolefin polymer, copolymer or blend. The anisotropic film layer has a F10 force Ratio (MD to CD) of at least 1.5. This anisotropic elastic web is usable in a variety of garment applications where an elastic is supplied in roll form and requires strength in a machine direction and elastic properties in a cross direction.Type: GrantFiled: October 4, 1996Date of Patent: March 23, 1999Assignee: Minnesota Mining and Manufacturing Co.Inventors: Jobst Tilman Jaeger, Alan J.
