Patent number: 6821936Abstract: Durable antimicrobial treatments for textile fabrics are provided. Such treatments preferably comprise silver ions, particularly as constituents of inorganic metal salts or zeolites. This particular treatment requires the presence of a resin binder, either as a silver-ion overcoat or as a component of a dye bath mixture admixed with the silver-ion antimicrobial compound. Such a treatment is extremely durable on such substrates; after a substantial number of standard launderings and dryings, the treatment does not wear away in any appreciable amount and thus the substrate retains its antimicrobial activity. The particular treatment method, as well as the treated textile fabrics are also encompassed within this invention.Type: GrantFiled: May 14, 2003Date of Patent: November 23, 2004Assignee: Milliken & CompanyInventors: David E. Green, Leland G. Close, Jr., Dirk L. Van Hyning

Patent number: 6787205Abstract: The invention relates to a coated food paperboard (1), to the manufacturing process and use of the same, and to products obtained thereof. The paperboard (1) comprises one or several fibre material layers (2), such as a three-layer structure consisting of a middle layer (4) of a mixture of sulphate pulp and CTMP and of sulphate pulp layers (5) on both sides of it, and of a polymeric coating (3) getting into contact with food, either on one side or on both sides of the paperboard. According to the invention, the coating (3) consists of an outer layer (6), the melting point of the polymer used in which is at least 230° C., and of an inner layer (7) placed against the fibre material layer (5); in this inner layer, a polymer with a melting point of at least 230° C. is blended with another adhesive polymer, the melting point of which is 130-185° C. Further, the inner layer (7) may be provided with mineral substance, such as calcium carbonate.Type: GrantFiled: October 10, 2001Date of Patent: September 7, 2004Assignee: Stora Enso OyjInventors: Yrjö Aho, Tapani Penttinen, Risto Salminen, Bruce Foster

Publication number: 20040161601Abstract: A unique primer emulsion chemistry yields excellent adhesion of polyethylene terephthalate (PET)resin to clay coated paperboard (with high starch content)at reduced coatweights of the primer emulsion and the resin as compared to other primer and tie-resin chemistries currently employed for moisture barrier applications. A primer used for adhesion enhancement is an ammonium catalyzed, self-crosslinking copolymer of ethylene-vinyl acetate with N-methylol acryl amide functional groups attached to a polymer backbone. Use of the primer in amounts up to about 0.5 pounds per ream permits PET coatweights of as low as 10-12 lbs per ream and lower for some applications.Type: ApplicationFiled: November 26, 2003Publication date: August 19, 2004Inventors: Ladislav Bednarik, Vivek Rohatgi, David V.
