Patent number: 6121165Abstract: Disclosed are articles useful in cleansing, and particularly wet-like cleansing wipes and toilet tissue. These articles are essentially dry to the touch prior to use, but deliver liquid when subjected to in-use shear and compressive forces. In one aspect, the articles of the present invention comprise a carrier and an emulsion applied to the carrier, the emulsion comprising a continuous external nonpolar phase and an internal polar phase dispersed in the external nonpolar phase, wherein the article is capable of retaining fluid prior to use. In another aspect, the emulsion-treated articles exhibit improved ability to release fluid when subjected to in-use pressures. The articles of the present invention offer a number of significant advantages over prior cleaning products when in the form of wet-like cleansing wipes such as those used for cleaning of hardsurfaces (e.g., floors, countertops, sinks, bathtubs, toilets, and the like) and wet-like toilet tissue.Type: GrantFiled: July 23, 1998Date of Patent: September 19, 2000Assignee: The Procter & Gamble CompanyInventors: Larry Neil Mackey, Gregory Charles Gordon, Nancy Kim Enright

Patent number: 6001749Abstract: A patterned conductive textile is provided by applying a finish to selected parts of a fabric which inhibits the formation of a conductive polymer coating on those areas. A conductive polymer is then oxidatively synthesized onto the remaining areas from an aqueous solution comprising the starting monomer, an oxidizing agent, and, optionally, a doping agent or counterion. The areas with the inhibitor finish remain substantially free of conductive polymer and a pattern of conductive and nonconductive areas is thus produced.Type: GrantFiled: July 30, 1997Date of Patent: December 14, 1999Assignee: Milliken & CompanyInventors: Andrew D. Child, Alfred R. DeAngelis

Patent number: 5938007Abstract: A conveying belt has a core and a canvas layer attached to the core. The canvas layer has a first surface facing the core and a second surface facing oppositely to the first surface. The canvas layer has a thickness between the first and second surfaces. The canvas layer is treated with fluororesin so that the second surface is impregnated with fluororesin and only part of the thickness between the first and second surfaces is impregnated with fluororesin.Type: GrantFiled: October 20, 1997Date of Patent: August 17, 1999Assignee: Mitsuboshi Belting Ltd.Inventors: Kazutoshi Fujihiro, Yoshinori Furukawa, Hiroyuki Ito

Patent number: 5899783Abstract: A fabric possessing both cleanability and fluid resistant properties is provided which can, if desired, be transfer printed. The fabric includes a textile substrate treated with a fluorochemical stain resist agent. The treated textile substrate is covered substantially on the back with a layer of extrusion coated thermoplastic polymer which is pressed at least partially into the fabric substrate. A process for forming the fluid shield fabric according to the present invention is also provided.Type: GrantFiled: February 12, 1997Date of Patent: May 4, 1999Assignee: Milliken & CompanyInventors: William Carl Kimbrell, Jr., Christopher Todd Usher
