  • Patent number: 6753063
    Abstract: The present invention relates to personal cleansing wipes articles which have superior softness, feel and cleansing properties. The wipes of the present invention comprise a substrate and an aqueous liquid cleansing composition which is coated onto or impregnated into said substrate to the extent of from about 100% to about 400% by weight of the substrate. The substrate is a single-layer, nonwoven substrate which is formed from hydroentangled fibers. Upon a substantial portion of a base surface comprising the substrate there exists a three-dimensional pattern comprising a plurality of discrete, raised fibrous regions. The raised fibrous regions have a density which is substantially the same as the density of the base surface. The raised fibrous regions are joined to the base surface by a fibrous transition region. The aqueous liquid cleansing composition comprises an effective amount of a cleansing surfactant.

  • Patent number: 6750165
    Abstract: A wet cleaning sheet 1 comprises an aqueous liquid-retaining layer 4 having an aqueous liquid-containing polymer and a chemical-containing layer 2 or 9 containing a chemical which causes the polymer to release the aqueous liquid. The aqueous liquid-retaining layer 4 and the chemical-containing layer 2 or 9 are formed and/or arranged in such a manner that they are kept out of substantial contact under no load applied but brought into contact with each other with a prescribed load applied whereby the aqueous liquid is gradually released from the polymer by the action of the chemical.

  • Patent number: 6746976
    Abstract: Disclosed are thin until wet materials that are suitable for use as acquisition members for absorbent articles (e.g., diapers, catamenial products, and adult incontinence devices). Preferred materials according to the present invention are either: 1) fibrous assemblies that utilize wet strength means to stabilize the material or 2) compressed regenerated cellulosic sponges so that, when the material is saturated with an aqueous fluid, it has an expanded wet density of between about 0.04 grams/cm3 and about 0.4 grams/cm3 and an expanded capillary desorption height of less than about 25 cm and a temporary binding means that helps maintain the material at a compressed dry density between about 0.06 grams/cm3 and about 1.2 grams/cm3 until the material is exposed to an aqueous fluid. The ratio of the compressed dry density to the expanded wet density is also greater than about 1.5:1. A suitable process for making the materials and absorbent structures using the materials are also disclosed.

  • Patent number: 6733861
    Abstract: A vehicle carwash element of the type which contacts the vehicle made by needle-punching three layers of synthetic strand material such as polyester, polypropylene or other polymeric strands. The quantities of material are arranged in layers with similar colors on the outside and a contrasting color on the inside. The layers are then needle punched to physically integrate them to the point of producing a unitary sheet-like body but insufficiently to totally blend the colors such that a center stripe of contrasting color appears on the edges of the resulting body and on any smaller body which is cut from the sheet which is manufactured according to the process described above.
