  • Patent number: 7842163
    Abstract: Tissue products are disclosed containing an additive composition. The additive composition, for instance, comprises an aqueous dispersion containing an olefin polymer, an ethylene-carboxylic acid copolymer, or mixtures thereof. The olefin polymer may comprise an interpolymer of ethylene and octene, while the ethylene-carboxylic acid copolymer may comprise ethylene-acrylic acid copolymer. The additive composition may also contain a dispersing agent, such as a fatty acid. The additive composition may be incorporated into the tissue web by being combined with the fibers that are used to form the web. Alternatively, the additive composition may be topically applied to the web after the web has been formed. After the additive composition is applied to the web or otherwise incorporated into the tissue web, the tissue web is embossed. During embossing, the additive composition forms well defined embossments in the web that are water resistant.

  • Patent number: 7303650
    Abstract: The present invention is generally directed to paper products having great softness and strength. The paper products are formed from one or more paper webs that can be made according to various methods. In one embodiment, the paper web is an uncreped through-air dried web. According to the present invention, at least one side of the paper web is treated with a bonding material according to a preselected pattern and creped from a creping surface. Through the process, a two-sided tissue web is formed having a smooth side and a textured side. In one embodiment, tissue webs made according to the present invention may also be splittable, allowing the web to be pulled apart in two substantially continuous webs with distinctly different properties.

  • Patent number: 7282116
    Abstract: Disclosed is a composition for softening an absorbent tissue. The composition includes an effective amount of a softening active ingredient; a vehicle in which the softening active ingredient is dispersed; an electrolyte dissolved in the vehicle; and a bilayer disrupter. The electrolyte and the bilayer disrupter cooperate to cause the viscosity of the composition to be less than the viscosity of a dispersion of the softening active ingredient in the vehicle alone. Preferably, the softening active ingredient is a quaternary ammonium compound with the formula: (R1)4?m—N+—[(CH2)n—Y—R3]mX? the vehicle is water, the electrolyte is calcium chloride, and the bilayer disrupter is a nonionic surfactant.

  • Patent number: 7267743
    Abstract: Waxes prepared from hydrogenated plant oils, such as castor, palm, and soybean, are used to prepare water based emulsions. The inventive waxes, obtained from naturally derived, renewable resources, were emulsified under anionic, cationic and nonionic conditions, producing emulsions having a solids content up to about 45% solids. When used to coat fibrous cellulosic articles, such as paperboard, the emulsions' performance was similar to emulsions containing petroleum-derived waxes. The inventive waxes have a low iodine value (between 2-5), and melting points between approximately 120-200 degrees F. (Mettler Drop Point). These waxes comprise a triglyceride whose fatty acids are predominantly stearic acid or ricinoleic acid.
