A sheet of material with an anti-skid surface, suitable for use as a roofing underlayment or wrapper, comprises a scrim made of woven plastic tapes with monofilaments that are round in cross-section and have a diameter larger than the thickness of the plastic tapes interwoven with the tapes. The monofilaments form ridges on the sheet material that impart an enhanced coefficient of friction to it. The monofilaments may be incorporated in the weave in the warp or weft directions or both.

In one embodiment a non-foamed thread is formed by extruding a mixture with a plastic material and a blowing agent. The non-foamed thread is arranged into a sole component and then heated to activate the blowing agent and cause the threads to foam. In some cases, the non-foamed thread is knitted together.

A flexible material is disclosed comprising a flexible substrate, a sorbent comprising zirconium hydroxide and a binder, wherein the solids weight ratio of the binder to the zirconium hydroxide is in the range 1:1 to 1:120. Also disclosed is a process for production of a fabric, comprising: providing a flexible material, providing at least one sorbent dispersion comprising zirconium hydroxide and a binder, applying the sorbent dispersion to the flexible material to produce a treated flexible material, squeezing the treated flexible material under pressure, and passing the pressed treated flexible material through a stenter.

A hollow weave fabric for an air bag in which the periphery of a double-layer hollow weave portion is formed with a seam zone, wherein the warp yarn and the weft yarn forming the base fabric are each a poly(hexamethylene adipamide) fiber having a total size of 150 to 500 dtex, the double-layer hollow weave portion has a fabric weight of 120 to 350 g/m.sup.2 on one side, and the fabric shows a logarithmic decrement of 0.01 to 0.10.

A sheet material with an anti-skid surface, suitable for use as a roofing underlayment or wrapper, comprises a scrim made of woven plastic tapes with monofilaments that are round in cross-section and have a diameter larger than the thickness of the plastic tapes interwoven with the tapes. The monofilaments form ridges on the sheet material that impart an enhanced coefficient of friction to it. The monofilaments may be incorporated in the weave in the warp or weft directions or both.

Polyurethane floor covering products are formed from a web layer containing at least 30% by weight fibers. A cooled polyurethane foam formulation which includes at least one polyisocyanate, water and at least one polyol having an equivalent weight of at least 500 is applied to the web layer. The wetted web layer is then compressed to mechanically wet out the fibers, gauged and heated to cure the foam formulation.

Lightweight, flexible protective fabrics for protecting a person, animal or other object from hot burning materials, hot high heat capacity and/or hot corrosive materials, such as hot molten metal, hot oily liquids (e.g., heating oil), hot gels, hot solids, hot sparks, and hot acids. The lightweight protective fabrics can be used to protect a person, animal or other object from hot molten metals, such as liquid metal zinc heated to a temperature of about 950 F. (510 C.) or greater, hot molten aluminum heated to a temperature of about 1150 F. (620 C.) or greater, burning phosphorus at temperature of about 1550 F. (843 C.) or greater, hot solid iron having a temperature of about 500 F. (260 C.) or greater, hot heating oil having a temperature of about 500 F. (260 C.) or greater, and hot hydrochloric acid having a temperature of about 300 F. (150 C.) or greater.

An abrasion resistant finish for a fungal material, the finishing comprising an optimum quantity biodegradable polylactic acid plastic (PLA) dispersed in water to produce a PLA mixture. When the PLA mixture is applied to the fungal material, water carries the PLA deeply into the matrix of the fungal hyphae to a depth at least 2 N/10 mm or 1% of the thickness of the fungal material, whichever is greater. The finish fortifies the hyphal structure as the water evaporates and creates a PLA coating on the fungal material with improved abrasion resistance and water resistance.
