  • Publication number: 20010010254
    Abstract: Application of radiation curable coatings to a flexible vinyl web, which is usually printed with a decorative pattern. This printed vinyl may be laminated to a backing for support and is often embossed. The actinically irradiated coated vinyl surface has improved stain resistance and is resistant to chemical attack by common as well as aggressive household cleaning solvents such as pine oil cleaners and nail polish remover. The coating is essentially free of hazardous volatile organic compounds and does not pose a toxicological threat to humans nor does it contaminate the atmosphere. These surface coated, actinically crosslinked vinyl laminates can be used in the manufacture of wallcoverings, automotive interiors, upholstery, tablecloths and other such applications especially where heat sensitive plastics are employed.

    Abstract: A surface coating applied on a substrate as well as a method of preparing a surface coated substrate are provided. A mixture comprising about 40% polyvinyl acetate and about 60% polyvinyl alcohol is applied to a porous substrate. Then, the mixture is heated. The polyvinyl alcohol cures by evaporation, and the mixture separates into a hydrophilic layer of polyvinyl alcohol and a hydrophobic layer of polyvinyl acetate, and the hydrophilic layer is between the hydrophobic layer and the substrate. A water-soluble ink is then deposited into the surface coating, and the ink is generally repelled by the hydrophobic layer, and is generally absorbed by the hydrophilic layer. Additionally, the hydrophobic layer protects from fading the ink which is absorbed into the hydrophilic layer, causes the ink to spread less in the hydrophilic layer, allows a charge to be applied to the same side of the substrate on which the ink is deposited, and allows an enhanced surface charge to be applied.

The dielectric is formed by evaporating an acrylate monomer having a molecular weight in the range of from 150 to 600. Preferably the acrylate monomer has a molecular weight to acrylate group ratio in the range of from 150 to 400. The acrylate condenses on the substrate and is polymerized in situ for forming a monolithic film with a sufficient thickness to produce an interference color.

  • Patent number: 5756156
    Abstract: A method for producing surface-treated paper, in particular of fine paper, and a dry end of a paper machine that makes use of the method. A paper web that has been dewatered by pressing is dried in the forward dryer section, in which drying energy is applied to the paper web over the entire length of the forward dryer section asymmetrically in the z-direction from the side of the bottom face of the web. This step is carried out by a number of successive groups with single-wire draw that are open downward. In this manner, shrinkage of the web both in the machine direction and in the cross direction is reduced or at least partially prevented, which shrinkage tends to take place when the dry solids content becomes higher. Paper broke is removed from underneath the drying groups that are open downward substantially by the force of gravity onto the broke conveyor placed underneath.

  • Patent number: 5733607
    Abstract: A method and apparatus for coating and curing fiberglass sleeving with an ultraviolet light curable acrylic includes the steps of singeing the fiberglass sleeve at a singeing station and thereafter, cooling the sleeve. The fiberglass sleeve is then coated with an ultraviolet light curable acrylic resin. Thereafter, the coated fiberglass sleeve is cured by passing it through a curing station wherein the sleeve is subjected to ultraviolet light radiation about its entire circumference. The process is speed adjustable and further, the intensity of the light emitted from the ultraviolet light source may be varied so that the system is tuned to cure fiberglass sleeves of any diameter up to approximately 1.00 inch.

  • Patent number: 5728424
    Abstract: A system for forming a textured surface on a geomembrane including a support surface, a first set of rollers for passing the geomembrane onto the support surface such that a surface of the geomembrane faces upwardly, a heater positioned in proximity to the surface of the geomembrane so as to heat the geomembrane to a desired elevated temperature, a particle distributer positioned above the geomembrane so as to pass solid particles onto the surface of the geomembrane in a desired particle distribution. The particles can have a desired size and geometry as they are passed onto the surface of the geomembrane. A second set of rollers is positioned adjacent to the port surface so as to receive the geomembrane after the particles have been distributed thereon. The heater includes a preheater positioned on one side of the particle distributor and a postheater positioned on an opposite side of the particle distributor.

  • Patent number: 5725909
    Abstract: A thermoplastic container or packaging material is given low oxygen permeability by coating with a crosslinked acrylate layer and a layer of oxygen barrier material deposited over the acrylate layer. Another acrylate layer may be deposited over the oxygen barrier. The oxygen barrier is selected from the group consisting of silicon oxide, aluminum oxide and metal. The acrylate layer may be formed from a photopolymerizable polyfunctional acrylate that is sufficiently low viscosity to be sprayed on the substrate or applied by dipping. Alternatively, the acrylate layer is a polymerization product of an acrylate monomer which is evaporated in a vacuum, condensed on the substrate and polymerized by irradiation by ultraviolet or an electron beam.

  • Patent number: 5716675
    Abstract: Compositions and methods for the post-production treatment of a starch-bound article to increase the flexibility of the treated article by softening or plasticizing the article through the application of a polyalcohol, preferably glycerin. The glycerin is preferably mixed with water before application to aid in penetrating the cellular matrix of the article. The glycerin acts as a plasticizer and a humectant, and it stabilizes the starch-bound matrix against warping that otherwise results when water-borne substances are applied to the surface of a starch-bound article. The glycerin treatment can be applied to a hinge to increase the resilience and durability of the hinge, generally by causing the inner hinge surface to be more collapsible, which greatly decreases the radius of bending of the outer surface of the hinge and which thereby reduces the amount of strain or elongation exerted on the outer surface of the hinge.

  • Patent number: 5702773
    Abstract: A method for blending fluorine into a polyimide free of fluorine comprises the steps of generating fluorine radicals in a fluorine based gas, removal of any charge particles from the gas to leave the fluorine radicals in the gas, and exposing a polyimide free of fluorine to an irradiation of the fluorine radicals so that the irradiated fluorine radicals penetrate into an inside of the polyimide without showing any reaction to the removed charge particles on a surface of the polyimide.
