  • Patent number: 10995451
    Abstract: The present invention relates to the field of denim fabric processing, specifically to an environmentally-friendly processing method for dyeing denim fabric with zero discharge. The method includes: step 1, a treatment of white warp yarns; step 2, a primary drying operation; step 3, a coating spray-dyeing operation; step 4, a secondary drying operation; step 5, a sizing operation; step 6, a ternary drying operation; and step 7, a doffing operation. In the present application, as warp yarns are dyed using the coating spray-dyeing technology, highly corrosive auxiliaries such as sodium hydrosulfite and sodium sulfide are not needed in the dyeing process, and the dyed warp yarns are not required to be treated in a washing tank, so that zero effluent discharge is achieved.

  • Patent number: 8863757
    Abstract: A process for reducing the permeability of a paper wrapper used in the construction of a smoking article is disclosed. The paper wrapper is treated with a film-forming composition that forms treated discrete areas on the wrapper. The treated discrete areas have a permeability within a predetermined range sufficient to reduce the ignition proclivity properties of a smoking article made with the wrapper. In accordance with the present invention, the film-forming composition contains a film-forming material. The film-forming material has a relatively low viscosity. In this manner, the film-forming composition can have a relatively high solids content and still be applied to the wrapper using conventional techniques, such as by using a gravure printer.

    Abstract: A decorative laminate includes a decorative layer and a core layer. The decorative layer is composed of a resin impregnated decorative sheet. The core layer is composed of at least one resin impregnated sheet of core paper. The core paper is impregnated with a resin composed of phenol formaldehyde resin and wood molasses. In this manner, a substantial portion of the resin used to impregnate the core paper is replaced with wood molasses, which results in a reduction of the cost of manufacturing the decorative laminate. The decorative laminate is manufactured by preparing a resin impregnated decorative sheet and preparing at least one resin impregnated core sheet by impregnating a core sheet with a resin composition composed of phenol formaldehyde resin and wood molasses. The decorative sheet and the core sheet are then layered to form a laminate lay-up that is heated and pressed to consolidate and cure the laminate.

    Abstract: The invention pertains to a method for the manufacture of a packaging material (1; 21) for the production of packaging blanks and packages and comprising the steps of providing at least on surface layer (2, 2′; 22, 22′) in the form of a continuous material web and substantially consisting of cellulosic fibres and applying a distance layer (3; 23) comprising a matrix material and reinforcement fibres thereto so that said surface layer (2, 2′; 22, 22′) is bonded to said distance layer (3; 23). The matrix material in the distance layer (3; 23) is in an expandable state when it is applied to the surface layer (2, 2′; 22, 22′) and is expanded in a separate process step, subsequent to the application step. The invention also concerns expandable packaging materials.

  • Publication number: 20030017310
    Abstract: The present invention comprises a wicket conveyor for conveying a series of wickets through pre-curing, curing and post-curing sections of a curing system. The wicket conveyor forms a continuous loop, having a straight upper track portion, a straight lower track portion and a pair of curved end portions of track that adjoin each end of the straight upper and lower track potions. Each wicket is attached to the wicket conveyor track such that the plane of the wicket is oriented at a predetermined angle. B wicket picks up a horizontally oriented sheet and carries it toward the pre-curing section. The wicket and substrate sheet are reoriented in response to the contour of the conveyor, into a near vertical planar orientation. While in the near vertical orientation, liquid coatings on the surface of the sheet substrate move down the substrate sheet in “sheet flow,” thereby leaving a smooth coating surface prior to curing.

  • Patent number: 6475566
    Abstract: The object of the invention is a method for improving the impregnability of refractory wood species by pretreatment with fungi of the genera Trichoderma o Gliocladium or with weakly wood-degraging fungi. The pretreatment comprises a thermal treatment of the wood, the addition of a nutrient medium as well as an incubation phase to promote fungal growth. The incubation phase is stopped when the desired depth of penetration of the fungus is reached. The wood is subsequently impregnated with a wood impregnating agent. The typical result of the fungal pretreatment is an incarease in the depth of penetration of the impregnating agent to a depth of penetration of 5 mm to 30 mm required depending on the intended use.

  • Patent number: 6383450
    Abstract: A method of producing a packaging laminate for aseptic packages of the type which is produced in that a web of the packaging laminate is, for the purpose of sterilization, led through a bath of hydrogen peroxide prior to the reforming of the web into aseptic packages. The packaging material is produced in that a web of paper which has, on the one side of the web, an applied outer coating of plastic, is, for the purpose of promoting adhesion, subjected to a surface treatment changing polarity, where after the treated outer plastic coating is provided with a decor of water-based printing ink which is applied in the desired pattern on the outside of the outer plastic coating.

  • Publication number: 20020025379
    Abstract: The present invention provides a method of applying ink containing dyes to fabric composed of synthetic and cellulose fibers using an ink-jet system to print the fabric with high color shade depth and brilliancy and ink-jet printed goods obtained by the ink-jet printing method. The fabric composed of cellulose and synthetic fibers is treated with an acidic aqueous dispersion containing cellulose reactive compound, water-soluble polymer and non-water-soluble inactive organic compound with a melting point of 40° C.-150° C. and the fabric is dried before its ink-jet printing with reactive and disperse dyes.

  • Patent number: 6348243
    Abstract: A cork stopper for a wine bottle or the like is coated with, for example, silicone rubber to prevent impurities in the cork from contaminating the contents of the bottle. The coating may be applied by dipping or immersion preferably with ultrasonic agitation to improve penetration of the coating material into the cork pores. Prior to coating, the corks may be soaked in a solvent to leach out taint compounds from the surface of the cork, thereby reducing the likelihood of such compounds concentrating on the coating surface.

  • Patent number: 6309704
    Abstract: A device for direct or indirect application of a liquid or viscous coating medium onto a moving material web, specifically a paper or cardboard web, includes an applicator unit which, in the direct application method, applies the coating medium in the form of a coating layer directly onto the material web at a point of application. In the indirect application method, the coating medium is first applied onto an applicator element, for example an applicator roll, which then transfers, at the point of application, the coating medium to the material web in the form of a coating layer. In addition, a drying device for drying of the coating layer is provided downstream from the point of application, viewed in the direction of flow of the material web. In the applicator unit, a device for moistening and/or warming the material web, coating medium or the coating layer is additionally provided before the drying device, viewed in the flow direction of the material web.
