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

A loose-fill insulation product having irregularly shaped glass fibers is provided. The loose-fill insulation product shows improved recovery, lower thermal conductivity and requires lower product densities than prior art loose-fill insulation at equivalent fiber diameters.

Loose-fill insulation having irregularly shaped fibers

A loose-fill insulation product is provided which may be poured or blown by a consumer. The insulation is comprised of irregularly-shaped glass fibers which are comprised of two distinct glass compositions. The loose-fill insulation product may be densely packaged in a small container for consumer use, and shows improved recovery, good thermal efficiency, and low dust upon blowing or pouring.

Pourable or blowable loose-fill insulation product

A loose-fill insulation product is provided which is formed from a blend of first and second insulating materials having three-dimensional groups of fibers of different sizes and densities. At least one of the insulating materials is comprised of irregularly-shaped glass fibers comprised of two distinct glass compositions. When blended with the fibers of a standard insulation or with other irregularly-shaped fibers of different sizes, the resulting loose-fill insulation product shows improved coverage and thermal efficiency.
