Abstract:
A surface covering product is disclosed which includes a layer of fused embossed PVC material on a substrate and a layer of transparent or translucent plastic material substantially covering the fused PVC layer and filling the embossed area of depression in the PVC layer. The surface covering product is made by applying the plastic material to the embossed surface of the PVC material and wiping off at least a portion of the plastic material. In one embodiment, a film of plastic material of substantial or minimal thickness remains on the fused PVC material. In another embodiment, the plastic material is completely wiped off the undepressed area of the fused granular material. The PVC material is preferably a granular material such as a stencil vinyl fine material. In one embodiment, the plastic material is a layer of minimal thickness substantially covering the stencil vinyl fine material.

Abstract:
A textured metallocene polyethylene foam sheet suitable for use in a floor covering is made using a highly co-activated azodicarbonamide package which blows the metallocene polyethylene effectively. The preferred co-activators are zinc oxide and urea. The textured surface of metallocene polyethylene foam is formed by a chemical embossing process which utilizes a liquid triazole having an alkyl moiety as a foam-expansion inhibitor. The triazole is dissolved in a non-polar solvent to form the foam inhibitor. The preferred inhibitor is a hydrocarbon which may be halogenated.

US Classification:
101129
Abstract:
The invention is directed to a method of printing a pattern on a substrate, the liquid retained within the printing screen is in a first position directly above the point of tangency between the screen and substrate so that a lesser quantity of liquid is deposited to provide raised beads of liquid comparable in size to the size of the apertures of the screen. The reservoir of liquid is shifted away from the point of tangency and therefore a larger quantity of liquid passes through the apertures because the apertures are now spaced from the substrate. The larger quantities of liquid flow together and therefore, a pattern is provided larger than the aperture size of the screen.

International Classification:
E04F 1516
US Classification:
428 48
Abstract:
Decoration polyvinyl chloride surface covering structures are described which have antistatic or static dissipative capabilities. Several features are described herein which can be taken advantage of to lower the normal conductivity of the polyvinyl chloride sheet and yet still maintain an attractive or decorative appearance.

Abstract:
The process for making a cellular surface covering having a multi-level embossed decorative wear surface by applying to a porous substrate a plurality of thermoplastic resinous inks developed from thermoplastic binders having different molecular weights and therefore different melt viscosities, the inks and substrate comprising a composite structure which also includes a blowing agent. The blowing agent may be either in the substrate or in the inks applied thereto. Upon final heating to fuse and foam all the resinous material of this structure, the metal viscosity differences of the resins in the inks provide varying degrees of physical resistance to expansion of the total system in the inked areas, thus producing multi-level design areas on the final product.
