  • Patent number: 8894814
    Abstract: Wiping products, such as facial tissues, contain an interior temperature change composition and an exterior hydrophilic lotion composition that can provide a cooling sensation when contacted with the skin of a user. The temperature change composition, for instance, can contain one or more phase change agents that undergo a phase change at slightly elevated temperatures. The phase change agents, in one embodiment, can have a relatively high heat of fusion. When undergoing a phase change, the phase change agents absorb heat and thereby provide a cooling feeling to the skin of a user. The hydrophilic lotion composition may contain a carrier and a thermo-reversible gelling agent. The hydrophilic lotion composition maintains the temperature change composition within the tissue and helps to prevent skin irritation.

  • Patent number: 8679295
    Abstract: The present disclosure relates generally to a tissue product having a creping composition disposed onto at least one surface thereof to increase the softness of the article, while retaining or improving manufacturing efficiency. 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.

  • Patent number: 7951266
    Abstract: A method of making absorbent cellulosic sheet with increased wet/dry CD tensile ratio includes treating the fiber at high consistency with debonder in a pulper, for example. The process enables the use of large amounts of debonder in a wet-press process in order to achieve wet/dry CD tensile ratios of greater than 30%.

  • Patent number: 7935222
    Abstract: A method for making an opacity relevant grade paper or paperboard product, such as a communication type paper used for printing and writing applications, utilizes an effective amount of quaternized alkanolamine fatty acid ester compounds as an opacification aid to control the optical properties of the paper or paperboard product as a wet-end additive to a papermaking operation. Using the quaternized alkanolamine fatty acid ester compound can improve the opacity of the paper or paperboard product, maintain the opacity of the paper while reducing the use of other opacification aids, such as inorganic fillers and/or pigments, and allow for a reduction in paper grammage without a compromise in opacity. The improvements in paper optical properties are achieved without adversely affecting other characteristics of the paper product such as bulk value, tensile strength, tear index, and the like.

  • Patent number: 7893115
    Abstract: An oil-in-water emulsion useful as a defoamer for pulp and paper mill applications is described. The defoamer has an oil blend (of a triglyceride oil or a mixture of triglyceride oils and silicone), a stabilizing agent (to make the oil blend stable in the emulsion), hydrophobic silica particles, surfactants, dispersants, and other components. The emulsion is usable directly at low concentrations to control foam.
