  • Patent number: 10316178
    Abstract: This specification discloses suspensions and method for making the suspensions. The suspension comprises a suspension medium and is loaded with an insoluble solid. The suspension medium is an aqueous solution made at least one soluble polymer and at least one thixotropic gum. The suspension medium can be loaded with high levels of solids (more than 15% by weight of the medium). The resulting suspension is highly stable and has low viscosity. In embodiments the suspension exhibits no significant sedimentation for at least 3 months, and has a viscosity of less than about 20,000 cP. In an illustrative embodiment, the suspensions may be used to improve the properties of corrugating adhesives by adding to a corrugating adhesive a suspension that has suspension medium comprising polyvinyl alcohol and gellan and that suspends unmodified high amylose starch.

Preferably the creping composition comprises a first component that is cationic and a second component that is capable of forming a film. Preferably both the first and second components are water soluble. The first component carries a cationic charge that is capable of forming ionic bonds with the negatively charged fibers of the tissue web, thus providing a retention mechanism by which the creping composition is retained. The overall retention of the creping composition reduces the concentration of the composition in the machine process water, improving machine operability and runability.

    Abstract: Sticky notes made from sugar cane paper and sticky note pads including same. Sticky notes are formed from sugar cane paper made from sugar cane bagasse. Sugar cane bagasse is the fibrous by-product that remains after sugar cane stalks are crushed to extract sugar-bearing juice. The use of bagasse to form the sticky notes is an environmentally sustainable alternative to sticky notes made from tree-based products.

  • Patent number: 8613830
    Abstract: A method of modifying the surface of a substrate which comprises a fibrous material. According to the present invention, the surface is brought into contact with a type of amphiphilic block copolymer which comprises one or several hydrophilic polymeric blocks and one or several hydrophobic polymeric blocks. Approximately 0.01-3 g/m2 of the amphiphilic block copolymer are applied onto the surface. With the help of the present invention, it is possible to effectively modify the surface of paper in such a manner that it produces a good surface for printing, for instance for ink-jet printing.

  • Patent number: 8613829
    Abstract: This invention relates to paper products and/or substrates suitable for being made into wallboard tape (also may be known as joint tape and/or drywall tape) and having improved reduction or inhibition in the growth of microbes, mold and/or fungus. The paper substrate is characterized by its excellent physical properties including cross direction (CD) tensile, machine (MD) tensile, internal bond, wet tensile, hygroexpansivity, curl, bonding properties, bonding of joint tape to joint compound, etc. The paper product of the invention contains a sizing agent and an antimicrobial compound as well as other optional components including without limitation a binder. The paper product of the invention may be produced by contacting the plurality of cellulose fibers with each of the sizing agent, antimicrobial compound, and optional components at any point in the papermaking process, converting process, and/or post-converting process. Finally, the invention relates to methods of using the paper substrate.
