Abstract: A roof covering includes a roofing mat formed from fibers of a fiber material. The fibers are coated with a sizing. The roof covering also includes a coating material that coats the mat. The coating material is based on an organic material. The sizing includes a sulfur-containing material that bonds to the fiber material. The sulfur-containing material has sulfur groups that form cross-links with the organic material. In another embodiment, the coating material contains sulfur added to the organic material. The sizing includes a bonding material that bonds to the fiber material and that bonds to the sulfur. The sulfur forms cross-links with the organic material.

Abstract: A method of repairing a paved surface utilizes a nonwoven or woven fibrous mat made from fibers including polymer fibers, the polymer fibers having a melting point greater than about 320° F. (160° C.). The mat has a load-elongation behavior such that when the mat is subject to tensile stress, the mat achieves at least 90% of its ultimate load at an elongation not greater than 5% of the specimen length in the direction of applied stress. Another mat comprises a nonwoven or woven fibrous mat made from fibers selected from the group consisting of mineral fibers, polymer fibers, natural fibers, and mixtures thereof, and a rubbery binder. Another mat comprises a nonwoven or woven fibrous mat made from a blend of high melt polymer fibers having a melting point of at least 350° F. (177° C.) and low melt polymer fibers having a melting point of less than 350° F. (177° C.).

Abstract: In a method of reinforcing and waterproofing a paved surface, a layer of liquefied asphalt is applied on a paved surface. A reinforcement mat is then applied over the liquefied asphalt. The reinforcement mat includes a first layer comprising a nonwoven mat produced from fibers selected from the group consisting of mineral fibers, polymer fibers, and mixtures thereof. The reinforcement mat also includes a second layer of mineral fibers attached to the first layer. The liquefied asphalt penetrates and soaks the reinforcement mat to form a water barrier. A layer of paving material is then applied a over the reinforcement mat. The first layer and the second layer of the reinforcement mat are attached to each other by any one of sewing, knitting, needling, heat treating, and adhering with an adhesive, or combinations thereof.

Abstract: In a method of reinforcing and waterproofing a paved surface, a layer of liquefied asphalt is applied on a paved surface. A reinforcement mat is applied over the liquefied asphalt. The reinforcement mat is a nonwoven mat produced from fibers having a melting point above about 320° F. (160° C.), and selected from mineral fibers such as glass fibers, polymer fibers, or mixtures thereof. The liquefied asphalt penetrates and soaks the reinforcement mat to form a water barrier. A layer of paving material is applied over the reinforcement mat.

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.

Abstract: A method is provided for forming a wet-laid nonwoven glass fiber mat comprised of a plurality of bundles of fibers. The method includes the steps of adding chopped fibers to a water slurry containing a sufficient amount of a suitable hydrophobic agent to cause the fibers to form a plurality of bundles. The fibers are then formed into a mat which may be used in a number of reinforcement applications. A method is also provided for modifying the components in the water slurry to produce mats comprising either bundles of fibers or dispersed fibers.

Abstract: 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.

Abstract: A glass fibrous mat is disclosed which includes a blend of fibers comprising approximately 70-90%, by weight 6.5-13.0 micron in diameter wool fiber and approximately 10-30%, by weight, 7.5-13.5 micron in diameter, 1/8 to 1/2 inch in length textile glass fibers bonded together with a resin, binder material comprising a melamine cross-linked styrene-butadiene resin. The glass mat has been found to be highly satisfactory for use as an interlayer for compressible vinyl floor coverings.
