The present invention provides a molding media and method of producing resin stabilized polymeric fiber mats useful as thermal and acoustical insulation. The molding media and method of the invention lower the cost of producing such mats while still maintaining the necessary mechanical and acoustical properties. One embodiment of the molding media and method of the invention further provides environmental advantages over glass fiber and foam mats.

Fibrous moldable media containing a foamed resin dispersed throughout

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. By using a non-woven fiber mat containing reinforcement fibers that are not completely straight and capable of interlocking with one another, a resilient sheet floor covering made with such a mat can exhibit improved planar compressibility.

Non-woven fiber mat and method for forming same

An irregularly shaped glass fiber is provided which enjoys improved resiliency, and openness in pack structures. Wool packs and other wool portions having such irregularly shaped fibers may be processed directly through needling to form a non-woven material without intervening steps such as carding or blending of fibers which accompany conventional glass fiber processing operations. In a further aspect of the invention, a non-woven material including irregularly shaped fibers in a generally continuous wool tow is produced by 'unwinding' a fiberglass wool pack collected by a direct forming method. Product applications include simplified, lower cost processing, and new uses of the irregularly shaped fibers produced by rotary fiberization in filtration elements, sorbants, gaskets, packings, shingles, composite structural elements, furnishings, textiles, yarns, and blown-in insulation systems.

Processing methods and products for irregularly shaped bicomponent glass

A facer sheet is provided which is adapted to receive a prefoam mixture during a structural laminate forming process. The facer sheet comprises a first predominantly glass fiber mat having first and second outer surfaces and a polymeric material applied to the first outer surface of the mat. The polymeric material acts as a substantially impervious barrier to the liquid prefoam mixture received at the second outer surface of the mat during the structural laminate forming process.
