An absorbent paper sheet is treated with an aqueous wax dispersion such that the sheet includes a fused wax and emulsifier residue in an amount of from about 1 to about 20 weight percent of the sheet based on the combined weight of the fiber, wax residue and an emulsifier residue in the sheet. The fused wax emulsion operates to make at least one surface of the sheet laterally hydrophobic, exhibiting a moisture penetration delay of at least about 2 seconds and less than about 40 seconds as well as a typical contact angle with water at one minute of at least about 50 degrees. There is thus provided absorbent products which exhibit both absorbency and resistance to moisture penetration. The treated sheet further exhibits microbial barrier properties, impeding transfer of bacteria, for example, through the sheet. There are produced tissue products which resist moisture penetration from propelled liquids as well as sequester sorbed liquids in the interior of the tissue.

Paper products treated on two surfaces with a liquid resistant composition are disclosed. The paper products can be, for instance, bath tissues, facial tissues, paper towels, and industrial wipers. The liquid resistant compositions can include any additive that provides benefits to the product. For instance, the liquid resistant composition can be a softener containing a hydrophobic additive. In one embodiment, the hydrophobic additive is a polysiloxane. In accordance with the present invention, the water resistant composition is applied to each surface according to a pattern. Each of the patterns includes treated and untreated areas. The patterns are positioned on the paper product such that untreated areas on one surface are in correspondence with the treated areas on the other surface of the sheet.

A disposable anti-microbial paper towel and dispensing method includes disposing paper towel in an automatic touchless dispenser which is adapted to generate a touchless proximity signal upon nearness of a consumer, and dispensing the paper towel in response to the proximity signal. A typical invention towel has: (i) a cellulosic web characterized in that the web is substantially without crepe bars and has an unlotioned MD bending length of at least 3.5 cm; and (ii) a transferable lotion composition comprising an emollient and anti-microbial agent, the lotion composition being immobilized on the cellulosic web in a semi-solid or solid form. The transferable lotion composition is selected from lotion compositions which are transferable upon contact with water or lotion compositions which are transferable upon application of body heat.

Fibrous sheet materials, such as are useful as facial tissue, bath tissue and paper towels, for example, are provided with chemical agents, such as certain salts, which create a temperature change in the sheet when exposed to a particular stimulant, such as water, for example. These materials can provide a soothing feel to the user, either in the form of cooling or heating, depending upon the particular chemistry involved.

Apparatus for dispensing sheet material from a roll of sheet material includes a rotatable sheet material engagement member having an outer surface for engaging the sheet material. A pivoted shaft is mounted adjacent to the sheet material engagement member having a feed roller mounted thereon. The shaft and feed roller are pivotally moved toward the sheet material engagement member and the feed roller is rotated to transport the sheet material over the outer surface of the sheet material engagement member. Spaced tucker members are connected to the sheet material engagement member and simultaneously rotate and pivot upon depletion of a primary roll of sheet material to position the lead end of a reserve roll between the sheet material engagement member and the feed roller.

Dispenser apparatus for dispensing paper toweling from a roll of paper toweling includes a paper toweling feed roller and a guide partially surrounding the feed roller having a curved guide surface spaced from the paper toweling feed roller. The feed roller and the guide form a curved passageway through which paper toweling passes during transport from a roll of paper toweling to a location external of the dispenser housing. Automatic transfer to a full roll of paper toweling takes place upon depletion of another roll.

Topically-applied binder materials for imparting wet strength to soft, absorbent paper sheets, such as are useful as household paper towels and the like, include an epoxy-reactive polymer, such as a carboxyl-functional polymer, and an epoxy-functional polymer.

Lightweight multi-ply tissue products, such as facial tissue and bath tissue, are produced by printing flexible polymeric binder material, such as certain latex binders, onto one or more inner surfaces of the multi-ply tissue product. The resulting products have low stiffness and high strength.

A first embodiment of this invention is a cleaning apparatus for a commercial conveyor belt that is mounted on a conveyor table. The cleaning apparatus is a housing that includes a spraying tube for dispensing a cleaning solution and a novel wiping device. The wiping device is constructed to apply a disposable towel, such as a paper towel, to the conveyor belt to remove the solvent including any contaminants while the conveyor belt is in motion. The used disposable towels are deposited into a waste container thereby requiring very little cleaning maintenance. By a second embodiment the spraying tube is eliminated and the disposable paper towels include a solvent (wet wipes) for removing the contaminants. The cleaning apparatus is preferably mounted on the underside of the conveyor belt next to a crumb tray so that the cashier can easily operate the cleaning apparatus.
