    摘要: Disclosed is a process for treating cellulosic fibers using an alkali metal hydroxide. The process first prepares the cellulosic fibers as a high consistency mixture with water and then adds an alkali metal hydroxide. The high consistency process is quite efficient and has been found to produce cellulosic fibers that are essentially uniformly treated. Also disclosed is a handsheet prepared from the treated cellulosic fibers for use is disposable absorbent products.

    摘要: An absorbent composition includes absorbent material, such as superabsorbent material, surface-treated with at least two different compatible agents. The superabsorbent material may be coated with multiple surface treatment agents in such a manner that each of the surface treatment agents is exposed on a surface of the superabsorbent material. For example, one surface treatment agent may be in a liquid coating form and another surface treatment agent may be in a powder form, each applied separately to the superabsorbent material.

    摘要: A method of modifying a two-dimensional, flat fiber morphology of a never-been-dried wood pulp into a three-dimensional twisted fiber morphology without the aid of a chemical cross-linker. The method includes the steps of treating a never-been-dried wood pulp fiber slurry with a drying aid and thermally drying the wood pulp fiber slurry. The method may alternatively, or additionally, include the steps of spray drying a wood pulp fiber slurry and/or a slurry of a hydrophilic material, and flash drying the spray dried wood pulp fiber slurry and/or slurry of hydrophilic material.

    摘要: A method for forming a tissue product that is soft and produces relatively low levels of slough is provided. The method includes providing a liquid furnish of cellulosic fibers and forming a multi-layered wet web therefrom. The web is dried (e.g., through-dried) to a solids consistency of 90% or greater. A latex having a glass transition temperature less than about 30° C. is applied to the dried web (e.g., foamed, printed, sprayed, etc.) such that the latex comprises less than about 3% by weight of the dry weight of the web. The latex remains substantially uncured after being applied to the dried web.
