Ultraviolet Radiation Patents (Class 8/115.53)
-
Publication number: 20130086753Abstract: A method for treating a fabric for protection from ultraviolet radiation is disclosed which comprises the steps of dispensing a suspension of zinc oxide particles treated with an acid polymer into a washing machine during a time in which a fabric is being washed in the washing machine and mixing the treated zinc oxide particles and the fabric for the treated zinc oxide particles to bind to the fabric. Other methods for treating a fabric for protection from ultraviolet radiation are also disclosed.Type: ApplicationFiled: October 1, 2012Publication date: April 11, 2013Inventors: Robert B Kramer, Ronald Kramer, Nicholas Marshall

Patent number: 8157872Abstract: A system, method and apparatus is disclosed for coloring a substantially wicking substrate comprising applying to a substantially wicking substrate an ink comprising a first dye and a second dye to define a region of reference; applying a first solvent to the substantially wicking substrate to move the first dye and the second dye within the body of the substantially wicking substrate; moving the two dyes in a defined direction to carry the two dyes outside of the defined region to color an area of the wicking substrate; coloring at least a portion of the substantially wicking substrate by allowing the first solvent to move through a portion of the first dye for a first distance from the defined point of origin of the ink and the second dye a second distance from the defined point of origin of the ink wherein the first distance is sufficiently different from the second distance to recognize a separation between the first dye and the second dye thereby coloring the substantially wicking substrate outside of thType: GrantFiled: April 24, 2009Date of Patent: April 17, 2012Inventors: James E.

Publication number: 20100304137Abstract: An article is provided that includes a polymeric fiber that has an excess number of surface active reactive moieties relative to the number of surface reactive moieties found on the fiber in a native state. A particle is bonded covalently to the fiber through an intermediate coupling agent. Multiple particles can be covalently bonded to the fiber, the multiple particles can be bonded uniformly or asymmetrically around the fiber diameter. A process for modifying a fiber includes creating surface activated reactive moieties thereon. The activated fiber is then exposed to a liquid solution containing a coupling agent to form a covalent bond. The coupling agent is also reacted with a particle in a liquid solution to form a covalent bond between the coupling agent and the particle. The coupling agent is covalently bonded to either a particle and then bonded to the fiber, or vice versa.Type: ApplicationFiled: August 13, 2010Publication date: December 2, 2010Applicant: U.S. GOVERNMENT AS REPRESENTED BY THE SECRETARY OF THE ARMYInventors: STEVEN H. MCKNIGHT, Robert E. Jensen, Joshua A. Orlicki

Patent number: 7179848Abstract: The invention concerns a method which consists in irradiating at least one face of the article with UV radiation, causing the article to be photodegraded over a thickness of at least 1 ?m, and in contacting the irradiated face of the article with a colouring agent so as to diffuse the colouring agent in the entire thickness of the photodegraded surface layer of the article. The invention is useful for optical and ophthalmologic articles.Type: GrantFiled: February 10, 2005Date of Patent: February 20, 2007Assignee: Essilor International Compagnie Generale d'OptiqueInventor: Gilles Baillet

Patent number: 6780827Abstract: Aqueous dispersions (U) containing: (A) a UV-light-absorbing textile treatment agent, (B) a dispersant system and (C) a carboxyl-containing crosslinked copolymer, and optionally (D) at least one formulation additive, are useful for the corresponding UV-active finishing of textile material, in particular textile material which can be dyed with disperse dyes or optically brightened with disperse brighteners, especially for treating cheeses with liquors comprising disperse dyes and UV absorbers or liquors comprising disperse brighteners, without fear of troublesome pressure build-up or dye or brightener deposits.Type: GrantFiled: February 26, 2001Date of Patent: August 24, 2004Assignee: Clariant Finance (BVI) LimitedInventors: Rainer Daus, Roland Grimm, Jürg Heller, Jean-Luc Mura

Patent number: 6211308Abstract: A method for coating a textile includes applying a substantially water-free, energy-curable, polymer-forming composition to the textile and exposing the textile and composition to a source of energy under such conditions as to generate chemically active sites on the surface of the textile and polymerize the composition. The resulting polymer is grafted onto the textile. Preferably, the energy is derived from electron beam radiation. The composition includes an epoxy oligomer having at least two ethylenically unsaturated moieties, and at least one alkoxylated polyol monomer having at least two ethylenically unsaturated moieties and capable of being copolymerized with the epoxy oligomer. Preferably, the composition also includes a surface active agent capable of rendering the uncured composition dispersible in water. Optionally, the composition can contain a colorant, and photoinitiator. The composition is especially suitable for use as a screen printing ink and coating material for textiles.Type: GrantFiled: August 20, 1998Date of Patent: April 3, 2001Assignee: Henkel CorporationInventor: Marie-Esther Saint Victor
