摘要:
The internal bulk of a tissue web can be improved during manufacturing of the basesheet by subjecting the tissue web to differential pressure while supported on a coarse fabric at a consistency of about 30 percent or greater. The differential pressure, such as by applying vacuum suction to the underside of the coarse fabric, causes the wet web to deflect into the openings or depressions in the fabric and "pop" back, resulting in a substantial gain in thickness or internal bulk. The method is especially adapted to improve the internal bulk of wet-pressed tissue webs.

A cleaning tool, such as a mop, used for cleaning a surface includes a cleaning head having a face with a plurality of projections extending therefrom. A cleaning pad is removably attached to the cleaning head face by engagement with the projections, the pad being formed of a first material having a thickness and composition such that the projections penetrate through the pad and extend beyond an outer planar surface of the first material. The projections thus serve to securely attach the cleaning pad to the head and also provide an abrasive scrubbing functionality to the cleaning tool.

Thin absorbent food pads with a bulk under 0.5 cm are provided having an insulation layer and from 3 to 30 sheets of compressed wet resilient cellulosic material wherein the absorbent pad has an absorbent capacity of at least 10 grams fluid per gram absorbent material and which expands in volume by at least 50%, relative to dry volume, upon wetting. The thin absorbent pads may be provided by calendering the insulation layer and cellulosic sheets under a force of about 100 to 1500 pounds per linear inch, thereby reducing the bulk of the pad by 30 to 60% and creating a pad which will significantly expand upon wetting to achieve an aqueous absorbent capacity of about 0.85 grams fluid per square centimeter (5.5 g/square inch).

Paper sheets, such as creped tissue sheets used for converting into tissue products such as facial tissue and bath tissue, can be softened with by passing the sheets through one or more fixed-gap noncompactive straining nips formed between two engraved rolls having partially-engaged small straining elements of a shape which strains the sheet in all directions. The straining treatment substantially reduces the rigidity of the tissue sheet by increasing the internal bulk without substantially reducing the tensile strength. The method provides a means for making a throughdried-like tissue sheet from a wet-pressed tissue sheet.

The present invention provides a distinctive article which includes at least one absorbent, fibrous web layer which is substantially non-hydroentangled. The fibrous web layer can have a basis weight of at least about 60 gsm, and a density of not more than about 0.25 gm/cc. The fibrous web layer can further have a peak geometric mean tensile strength of at least about 250 grams-force per centimeter of width, and can have a fiber content in which at least about 90 wt % of the fibers are composed of fibers having a fiber length of not more than about 0.4 inch (about 1 cm). In particular configurations, the article includes a backsheet layer, and a liquid permeable topsheet layer which is disposed in facing relation with the backsheet layer. An absorbent structure is interposed between the backsheet layer and the topsheet layer, and the absorbent structure has an overall absorbent capacity of at least about 300 grams of saline.

The present invention discloses a process and a method providing a high bulk tissue which is both strong and soft. Specifically, it has been discovered that certain low pressure printing technologies may be used to deliver a bonding material to the surface of a high bulk paper web such as an uncreped, through-dried web. The bonding material may be applied to the web either before, during or after the web is softened with a mechanical straining process which will decrease the web bulk by no more than 20% of the initial bulk in order to increase the web softness. The web may be softened by any of a variety of mechanical straining processes such as, for instance, microcreping, microstraining, rush transfer, or other low-compressive softening methods. The cured bonding material on the web may not only increase the bulk of the web when dry and wet, but also increase the wet resiliency and the wet strength of the web.

A RFID method and system are provided for ensuring that personnel are properly outfitted with necessary equipment for performance of a particular task or procedure. RFID smart tags are configured with the required pieces of equipment, the smart tags containing information to identify their respective pieces of equipment. A RFID scanner is disposed at a location through which an individual passes prior to performance of the procedure. The scanner interrogates the smart tags and determines if the individual has all of the required pieces of equipment.

Free flowing particles useful in absorbent articles are disclosed, including fibrous nits and methods of preparing fibrous nits. In one embodiment, fibrous nits are prepared from disperging cellulosic fibers in the presence of a nit conditioner which modifies nit particle size and properties for improved performance of the particles. In other embodiments, nits are prepared in multiple disperging steps or by disperging fibers under two or more conditions.
