摘要:
In some embodiments, a nonwoven fabric includes a first web that is at least partially formed of extruded strands which include an auto-adhesive material. The nonwoven fabric is adapted to be bonded to another item that includes a similar auto-adhesive material. In other embodiments, a method of forming a nonwoven fabric includes extruding a plurality of strands that are formed of an auto-adhesive material. The method further includes routing the plurality of strands toward a moving support, depositing the plurality of strands onto the moving support, and then stabilizing the plurality of strands to form a web. In other embodiments, a fastening system includes a nonwoven fabric that has a web which is formed of a plurality of extruded strands that include an auto-adhesive material. The fastening system further includes a foam layer that has a surface with a plurality of free-standing struts that include a similar auto-adhesive material.

The present invention relates to an apparatus for applying a liquid coating onto an object. The apparatus includes a device that has a handle and a transfer medium which is attached to the handle. The apparatus further includes a cover that is attached to the device. The cover includes a closure element that is operable to open and close an end of the cover. When the end of the cover is open, the cover is movable between a first position where the cover protects the transfer medium and a second position where the cover protects the handle. In another example embodiment, the cover is formed of a removable first layer that is positioned adjacent to the transfer medium when the cover is in the first position and a removable second layer that is positioned adjacent to the handle when the cover is in the second position.

The present invention relates to a decal and method for treating a surface. The decal includes a web and an agent for treating the surface. The decal further includes a bonding material that attaches the decal to the surface. In some embodiments, the agent may be attached to the web while in other embodiments the agent may form part of the web. In one embodiment, the agent includes a composition formed of Urea HP and boric acid. In another embodiment, the agent includes a composition formed of polyhexamethylene biguanide and boric acid. In still another embodiment, the agent includes a composition formed of Urea HP and polyhexamethylene biguanide. In yet another embodiment, the agent includes a composition formed of polyhexamethylene biguanide and benzoic acid. In another embodiment, the agent includes a composition formed of polyhexamethylene biguanide and propionic acid.
摘要:
An absorbent article with improved body fit wherein a combination of downward-deflecting crease lines and an upward-deflecting shaping line are used in outer and central absorbent members, respectively, to achieve a form-fitting geometry in the crotch region while also enhancing control over fluid flow in the article. Embodiments with wicking barriers between the outer and central absorbent members are especially useful in achieving leakage reduction.
摘要:
An absorbent article is disclosed comprising a thin, flexible wicking barrier with a horizontal portion that is folded back upon itself to create a substantially longitudinal cuff. The wicking barrier can separate a central absorbent member from an outer absorbent member for improved center fill, with the cuff open toward the central absorbent member to intercept liquid flowing toward the longitudinal sides of the article. The wicking barrier cuff desirably contains spacer means to hold the cuff open, providing void space to receive fluid. In one embodiment, lateral compression of the article during use causes the wicking barrier cuff to lift up from the surface of the article, creating a bubble of topsheet material and wicking barrier material (a “dynamic bubble cuff”) that intercepts fluid and improves body fit and leakage prevention.
摘要:
Paper sheets useful for tissues, paper towels, napkins, disposable absorbent products and the like can be made to exhibit a high degree of wet resiliency. This property is achieved by using a combination of high yield pulp fibers (such as bleached chemithermomechanical pulp fibers) and a wet strength agent in an uncreped throughdrying process. The resulting product, when wetted, can spring back after being crumpled in one's hand.
摘要:
A method of making fiber bundles and fibrous structures. The efficacy of a fiber bundle in handling complex fluids may be improved by subjecting an aqueous suspension of fibers at high consistency to elevated energy input with sufficient working of the fibers. The fibrous structures prepared according to the methods herein include at least one fiber bundle and at least one debonding agent. The fiber bundle includes at least one particulate material consisting essentially of entangled fibers.
摘要:
Absorbent articles containing absorbent cores of fluff pulp frequently contain wrinkles in the absorbent core that run from side to side of the article, typically normal to the machine direction in the manufacturing process. Side-to-side wrinkles are deleterious in that they provide large flow channels for urine or other body fluids to escape to the edge of the article. Frequently, such wrinkles are present after manufacturing, before the article has been folded or worn. The cause of the wrinkles is believed to be due to natural instabilities during compression of the fluff pad shortly after it is formed. Means for reducing cross-directional wrinkles include the use of grooved, drilled, or patterned compression rolls to densify the fluff pulp while providing opportunities for reduced in-plane displacement during compression or, if in-plane displacement does occur, providing paths for cross-directional displacement as well as machine-direction displacement so that continuous CD wrinkles cannot form. The use of large diameter rolls with soft rubber covers can also be used.

A disposable urinary incontinence device comprises a liquid-stable resilient member and a cover sheet. The cover sheet envelops the liquid-stable resilient member to form an elongated member having a tubular profile. The elongated member has a first end, a second end. The cover sheet exhibits a skin-facing surface contact area of less than 30% at a depth of 10% of the cover sheet. In addition, the cover sheet has a static coefficient of 0.275 to 0.150, and a dynamic coefficient of friction of 0.230 to 0.150.
