This invention relates to a method for producing a decorative reflective surface covering with improved adhesion of the various layers, having a backing, metallic areas and a transparent top layer, and the product thus produced. This product is produced by applying an adhesive on the surface of a backing in regular, spaced intervals, bringing a metal face of a film in contact with the adhesive to secure it to the backing, removing the metal film whereby the areas in contact with the adhesive remain on the backing and then applying a transparent layer to the surface of the backing covering the remaining metallic areas.

Process for preparing high reflectivity decorative surface coverings

High reflectivity in flooring and other products

A polyurethane coating, coating composition and coated substrate wherein the coating is essentially one macromolecule of homogeneous structure wherein the nitrogen atoms of the urethane groups are joined to alicyclic rings and/or straight aliphatic chains and the main polyurethane chains are crosslinked by three types of crosslinkages; via isocyanate residues and triol or tetrol residues, reactive upon curing by exposure to heat; via double bonds in vinyl compounds reactive, upon curing by exposure to radiation, with acrylo groups incorporated as acrylate esters into the polyurethane structures; and via urea groups formed by action of moisture upon isocyanate groups which are unreacted in the heat and radiation curing steps. On an equivalent weight basis, the ratio of all double bond crosslinkages: urethane crosslinkages is between 1.0 and 2.5; the content of urethane groups in the main polyurethane chains is from 40% up to no more than 70% of total equivalents of originally present isocyanate groups; the content of urethane crosslinkages on the same basis is 20-40%, and the content of urea groups on the same basis is about 5 to 25%. One particularly suitable substrate is resilient, foamed, embossed polyvinyl chloride yard goods such as used for floor covering.

Stain resistant, abrasion resistant polyurethane coating composition,

Pile fabrics, which have been prepared from nylon carpet fibers having a textured or embossed surface induced by a chemical shrinking process for developing the texture of the fabric, involving selectively contacting the surface of certain areas of the carpet with a chemical fiber shrinking agent for the nylon fibers and allowing the shrinking action to occur, and thereafter, removing the shrinking agent from the fibers, the thus treated areas, thereafter, showing a reduced height of pile to create the texture of the fabric, are kept soft in the treated areas by simultaneously incorporating in the shrinking material, or of the dye composition used as a combination color and shrinking material, a protective agent compatible with the fiber and also one which is not destroyed by the chemical nature of the shrinking or dyeing compositon to maintain the shrunk fibers soft and pliant.

Chemically embossed carpet and the method of carrying out chemical

A method of improving the bond between a vinyl resin material and a polyurethane or acrylated polyurethane resin material which comprises coating a fused vinyl resinous layer with an aqueous acetic acid solution, drying the aqueous coating, applying an uncured polyurethane or acrylated polyurethane layer to the coated surface of the vinyl resin material and exposing the vinyl resinous composition layer and the uncured polyurethane or acrylated polyurethane resin layer to curing conditions to develop a strong and permanent bond between the two layers.

Method of improving the adhesion of polyurethane to vinyl resins

Multi-level nylon pile fabrics having a selectively etched surface and a process of developing an etched effect that comprises selectively applying a chemical fiber etching agent to the surface of a level pile fabric, controlling the depth of penetration into said fabric and heating in the presence of steam to a temperature of 180.degree. F.-250.degree. F. to destroy part of the pile in the treated areas and thus to reduce the height of the pile in the treated areas creating the desired multi-level effect.

Carpet etching

Methods of forming liquid, low viscosity, low molecular weight, cross-linkable, stable polyurethane prepolymers which comprise: reacting polyisocyanates, and preferably aliphatic and cycloaliphatic diisocyanates, with polyhydroxy compounds or polyols, and preferably diols, triols, tetrols, and mixtures thereof; the polyols having a molecular weight of from about 62 to about 3000; the polyisocyanates and the polyols being added to the reaction mixture in an NCO/OH ratio in the range of from about 0.7:1 to about 6:1, and preferably from about 1.6:1 to about 4:1; the reaction taking place preferably in an inert, non-reactive organic solvent such as xylene; in the absence of any reaction catalysts, or in the presence of a relatively very low concentration of reaction catalysts of from about 0.00005% by weight to about 0.8% by weight, based on the total weight of the reaction mixture; at a reaction temperature of from about 0.degree. C. to about 70.degree. C., and preferably from about 0.degree. C. to about 40.degree. C., for a reaction time of from about 1/2 hour to about 12 hours; and terminating the reaction short of completion at a percent completion of reaction of from about 2% to about 95%, and preferably from about 30% to about 80%. The resulting liquid, low viscosity, low molecular weight, cross-linkable, stable polyurethane prepolymers are also included in the inventive concept.

Method of forming storage-stable polyurethane prepolymers

In a process for manufacturing a resilient, resinous floor covering having a polyurethane surface coating, the in-line manufacturing improvement which comprises: applying to a foamable resinous sheet material a urethane coating composition having a viscosity in the range of from about 10 centipoises to about 100 centipoises, the application of the urethane coating composition being accomplished by a reverse-roll coating procedure wherein the casting ratio is in the range of from about 0.8:1 to about 1.1:1; and then, in an in-line manufacturing step, heating the coated, foamable, resinous sheet material to dry and to cure the urethane coating composition and to blow the foamable, resinous sheet material to form a resilient, resinous floor covering having a polyurethane surface coating, the curing of the urethane coating composition not being in excess of about 80% during the heating and blowing of the foamable resinous sheet material.

Processes of applying urethane top coatings to resilient floor coverings

An improved process of developing an embossed effect in nylon pile fabric, particularly carpet, that comprises selectively contacting the pile surface of the foregoing fabric with a chemical fiber shrinking agent in combination with a penetrant vehicle capable of increasing materially the penetration of the shrinking agent into the fibre surface, and, correspondingly, the depth of embossing caused by the shrinking agent's action in reducing the length of the treated pile.
