Abstract: A spiral wound product having indicia thereon. The indicia are disposed on the ends of the product, resulting in less ink usage while providing a functional benefit or an aesthetically-pleasing pattern which can last for the life of the product. Optionally, indicia may be applied to the XY surface of the product as well. The invention is applicable to paper products dispensed from a core, as well as coreless spiral wound paper products. This invention is also applicable to cut-and-stack configurations where the product may be dispensed from a package. The product may be dispensed from the package in either a reach-in or pop-up mode.

Abstract: A soft tissue product and method for making a soft tissue product which exhibits resistance to limiting while maintaining physical strength integrity. The process includes debonding and mechanically treating papermaking fibers, forming a tissue web and drying the tissue web. The process allows for the use of high levels of debonding agents and hardwood fibers.
Abstract: An anhydrous lotion composition for killing viruses and bacteria in addition to imparting a soft, lubricious, lotion-like feel when applied to tissue paper and tissue paper treated with such lotion compositions are disclosed. The antiviral action of the lotion is due to the addition of an organic acid such as citric acid or salicylic acid. The antibacterial action is due to the addition of antibacterial agents such as TRICLOSAN®. The solubilization of the antiviral and antibacterial agents within the lotion matrix is aided by the addition of hydrophilic solvents and hydrophilic surfactants. The lubricious lotions also contain a plastic or fluid skin conditioning agent such as petrolatum, an optional immobilizing agent such as a fatty alcohol or fatty acid to immobilize the skin conditioning agent on the surface of the tissue paper web and a hydrophilic surfactant to improve wettability when applied to toilet tissue.

Abstract: A tissue which has at least one fibrous ply. A hydrophobically treated foam stratum is placed on at least one of the fibrous plies in order to prevent the penetration of moisture through the tissue. A hydrophobically treated foam can also be impregnated into one or more fibrous plies in order to provide a barrier to the penetration of moisture through the tissue. The invention also comprises a process for making tissue with a foam moisture barrier.
Abstract: The present invention relates to a flushable fibrous structure that is particularly useful as a disposable tissue product and as a component (e.g., topsheets) for absorbent articles such as catamenial pads, diapers, incontinent articles and the like. The invention specifically relates to a flushable fibrous structure that has an in-use wet tensile strength of at least about 100 g/in. and a disposal wet tensile strength of not more than about 30 g/in. The invention also relates to absorbent articles comprising the fibrous structures, and methods for making the structures.

Abstract: A method for the manufacture of creped hygienic cellulose paper, in particular. A hemicellulose containing additive, in particular galactomannan, xylan or highly milled birch pulp, is added to the pulp either prior to the pulp being deposited on the wire of the paper machine, after the pulp is deposited on the wire of the paper machine, or both before and after the pulp is deposited on the wire. As a result of this measure, the strength of the paper web thus produced and its runnability properties are substantially improved, while the softness virtually remains unchanged. In addition, the energy requirements for drying the paper web are substantially reduced.
