In one embodiment of the present invention, the lotion composition includes water in an amount up to about 90% by weight of the lotion, an emollient component in an amount up to about 20% by weight of the lotion, a fatty alcohol component in an amount up to about 50% by weight of the lotion, an emulsifier component in an amount up to about 40% by weight of the lotion, and a skin conditioning component in an amount up to about 60% by weight of the lotion. Typically, the add-on level of the lotion composition is between about 1% to about 15% by weight of the paper product. As a result, the paper product can be used to dry the hands of a user, while also imparting certain benefits to the skin as well.

Paper products treated with oil-in-water emulsions

The present invention may provide a towel desirably including first and second layers having cellulosic fibers and a repellant agent. The first and second layers may substantially sandwich a third layer having cellulosic fibers with higher absorbency than the first and second layers. All three layers may form a single ply.

High utility towel

The present invention provides compressed paper webs that maintain a substantial amount of their absorptive capacity and wet strength when compressed. The compressed webs bounce back to a portion of their uncompressed state when wetted. The present compressed webs allow more towels to be added to a dispenser without substantially sacrificing the absorbent capacity or the strength of the towels.

Compressed absorbent fibrous structures

A product and process of making an absorbent paper article such as paper products, towels, napkins and the like is disclosed. In the invention, one may supply a single furnish, or slurry, of cellulose fibers. Then, it is possible to separate or fractionate the slurry into at least two portions based upon fiber length in the slurry. Fines are employed in the process of manufacturing the products, and fines are specifically incorporated into an inner layer of the final paper products. Fines, short fibers, and/or fibrils are used in the process so they may contribute in a positive manner to the final paper product, rather than acting in a negative manner as a chemical &ldquo;sponge&rdquo; or waste material. This use of fines in the inner layers of the product reduces the manufacturing cost and waste produced in the process. A soft paper product with good strength characteristics results from the process.

Method of making absorbent tissue from recycled waste paper

A method of making sanitary paper products from coarse fibers. The method includes the steps of: (a) pulping coarse fibers in water with agitation to produce a pulp slurry, the pulp from the coarse fibers having an average fines content of greater than about 40%; (b) using an effective amount of pulp washing to reduce the fines content and increase the Canadian Standard Freeness; (c) introducing the pulp at a papermaking consistency into the headbox of a paper making machine; and (d) utilizing the pulp in a paper making process to produce sanitary paper products.

Method of making sanitary paper product from coarse fibers

A process of recovering a useful population of fibers and fines from the waste stream of fiber processing facility is disclosed. Steam explosion of the fiber-containing waste stream is used to increase the separation efficiency of the fibers from the ash. The steam explosion also enhances the quality of the recovered fibers and fines, providing a population of recovered fibers which can be incorporated into the fiber component of a tissue or absorbent paper product.

Recovery of fibers from a fiber processing waste sludge

A toilet tissue product may include a first cellulosic ply and a second cellulosic ply. Desirably, the first cellulosic ply further includes a single layer and the second cellulosic ply further includes a single layer. At least one ply may have a region that prevents fluid from striking through the tissue product.

Tissue with strikethrough resistance

A method of making sanitary paper products from recycled newspapers. The method includes the steps of: (a) pulping newspapers in water with agitation to produce a pulp slurry, the pulp from the newspapers having an average fines content of greater than about 40% and a Canadian Standard Freeness of less than about 250; (b) washing the pulp, whereby the fines content is reduced to less than about 35% and the Canadian Standard Freeness is increased to more than about 300; (c) introducing the treated pulp at a papermaking consistency into the headbox of a paper making machine; (d) adding from about 0.01% to about 1.5% of a surfactant system to the treated pulp; and (e) utilizing the treated pulp in a paper making process to produce sanitary paper products.

Process for modifying pulp from recycled newspapers

Methods are provided for preparing absorbent material, comprising providing non-broken down and uncut recycled fiber sludge having a moisture content of greater than about 40%; pelletizing said recycled fiber sludge to form wet pellets; and drying said wet pellets. The absorbent material is particularly useful as an industrial-grade waste liquid absorbent and/or an animal litter.

Process for the preparation of absorbent materials

The present invention provides a core for receiving a wound product wherein the core is made of a waste sludge produced in a papermaking process. The process for making the core includes the steps of mixing the sludge with a binder material, which may be either a wet strength or a dry strength agent, and then compressing the mixture into a core through a process such as extrusion or molding. Optionally, the sludge may be dried prior to mixing with the binder material.
