BACKGROUND OF THE INVENTION1. Technical Field
This invention relates to a non-woven or woven fabric containing cotton and whose properties are enhanced by coated or saturated substances; to the method of forming this material; to components that are surfaced and/or saturated by this material; and to the method of forming those components. More particularly, this invention relates to a non-woven or woven fabric pad containing cotton and in some embodiments also containing, soap (wet or dry) liquids or creams for: human skin cleansing and/or exfoliation; cleaning of surfaces. The invention preferably takes the form of hand held pads and/or cloth wherein the material produces mild surface abrasion and pleasing stimulating tactile sensation to the skin of the user.
2. Background Information
The current standard non-woven and woven substrate materials that are enhanced by coated substances that are designed for cleansing and exfoliating human skin typically are made of thermoplastic non-cotton materials. Disposable wipes for human skin that are made of mostly thermoplastic substrates are not typically biodegradable and will not decompose in an eco-friendly manner. Current one hundred percent (100%) cotton wipe materials on the market, claimed as textured or exfoliating, involve using cotton that is a hydro entangled non-woven with apertures (small holes) that give the impression of exfoliating.
It would be desirable to have a cleansing and/or exfoliating or cleaning material that overcomes the above short comings of the presently used mostly thermoplastic substrate human skin wipes.

The cotton wipe sheet has a wipe surface and an opposing back surface. The plurality of beads is adhered to the wipe surface. Each bead is formed to have a three dimensional geometry that extends outwardly from the wipe surface.
According to another aspect of the invention, a textured wipe is provided that includes a non-woven or woven cotton wipe sheet and a plurality of beads. The cotton wipe sheet has a wipe surface and an opposing back surface. The plurality of beads is adhered to the wipe surface.

The cotton wipe sheet 12 includes a wipe surface 14 and an opposing back surface 16. For those applications where the wipe 10 is designed to be used as a cleaning and/or exfoliating wipe for human skin, a sheet thickness 17 of approximately 0.15 inches (˜0.38 mm) provides advantageous durability. The cotton wipe sheet 12 is not limited to this thickness 17, however. In some embodiments, the wipe sheet 12 includes a backer sheet 18 (see
In some embodiments (e.g., see
In a first embodiment, each bead 20 includes a puffing agent. Puffing agents are commercially available. An example of an acceptable commercially available puffing agent is Altoma Super Puff 406, from Bolger & O'Hearn, Inc. of Fall River, Mass., U.S.A. The composition that forms the bead 20 may also include an appropriate binding agent such as an acrylic emulsion that enhances the adherence of the composition, including the puffing agent, to the cotton wipe sheet 12. As will be described below, when a puff agent is exposed to an elevated temperature (e.g., elevated over ambient) it expands to at least in part create the three dimensional shapes of the beads 20.
In a second embodiment, the beads 20 comprise a thermoplastic material. Examples of acceptable thermoplastic plastics include, but are not limited to, one or more of polypropylene (“PP”), polyethylene (“PE”), acrylonitrile butadiene styrene (“ABS”), polyamide (“PA”; also referred to as “Nylon”), polyethylene terephthalate (“PET”), polyvinyl chloride (“PVC”) or copolymers thereof. In this embodiment, the beads 20 may also include materials including abrasive particles and/or acrylic resin(s).
Now referring to
A variety of methods can be used to manufacture the present textured wipe 10. In those embodiments wherein the textured wipe 10 includes a plurality of beads 20 that include a puffing agent, the material that forms the beads 20 can be applied to the cotton wipe sheet 12 via an aqueous composition applied via a printing technique such as screen printing using a rotary screen printing machine. In this technique, the aqueous composition is forced through a specially prepared screen onto the cotton wipe sheet 12. The screen does not allow the passage of the aqueous composition through the screen except in defined openings. The positioning of the openings creates a predetermined pattern of the aqueous composition on the surface of the cotton wipe sheet 12. The particular pattern used can be varied to suit the application at hand; e.g., more or less beads 20, spacing between beads 20, etc. The size of the openings also is a factor in the amount of aqueous composition that passes through the openings, and therefore the size of the beads 20; e.g., all of the beads 20 may be of the same size, or certain beads 20 may be bigger or smaller than others, etc. After the aqueous composition is applied to the cotton wipe sheet 12, the sheet is subjected to a drying step at an elevated temperature (e.g., by microwave energy, infrared heating, steam, autoclaving, etc.), at which time the puffing agent forms a gas which causes the composition deposits to rise and create a three-dimensional shape on the substrate. As indicated above, in some instances, a binding agent may be added to the composition to enhance the adherence of the composition to the cotton wipe sheet 12. In some instances, the textured wipe 10 may be subsequently exposed to a second heat process for curing the deposited composition. Optimum drying and curing temperatures and durations can vary depending on the exact chemistry of the composition applied to the cotton wipe sheet 12.
In those embodiments wherein the textured wipe 10 includes a plurality of beads 20 that comprise a thermoplastic material, the material that forms the beads 20 can be applied to the cotton wipe sheet 12 via a die process wherein the thermoplastic material is extruded or otherwise forced through an applicator (e.g., a plate) having a plurality of holes arranged in a predetermined pattern. Like the screen described above, the positioning of the holes within the applicator and the pattern formed thereby can be varied to suit the application at hand; e.g., more or less beads 20, spacing between beads 20, etc. Also, the size of the openings can be varied to make the beads 20 all the same size, or make certain beads 20 bigger or smaller than others. After the bead 20 material is applied to the cotton wipe sheet 12, the sheet may be subjected to additional steps including one or more of a bead geometry forming step, a drying step, and a curing step, the latter operable to cure the thermoplastic material within the bead material. Also as indicated above, in some instances, a binding agent may be added to the bead material to enhance the adherence of the composition to the cotton wipe sheet 12. Optimum drying and curing temperatures and durations can vary depending on the exact chemistry of the bead material applied to the cotton wipe sheet 12.
In those embodiments wherein the textured wipe 10 includes a coating 28 adhered to the wipe surface 14 of the cotton wipe sheet 12, the coating 28 can be applied using conventional aqueous coating techniques that allow the aqueous solution to wet the cotton wipe sheet 12 and upon drying, adhere well to the fibers of the cotton wipe sheet 12. In these embodiments, the coating 28 may be applied to the entire wipe surface 14 or portions of the wipe surface 14; e.g., in a pattern. As indicated above, the coating 28 may also be used in combination with any of the textured wipe 10 embodiments that include a plurality of beads 20 applied to the wipe surface 14. For example, a coating 28 that includes one or more of a skin cleaning agent, a medicinal agent, an exfoliating agent, and a soap material can be applied to the wipe surface 14 after the beads 20 are applied. Alternatively, the beads 20 could be applied to the wipe sheet 12 and the coating 28 could be applied to the exposed surface of the backer sheet 18.
Referring to
Although this invention has been shown and described with respect to the detailed embodiments thereof, it will be understood by those skilled in the art that various changes in form and detail may be made without departing from the spirit and scope of the invention. For example, in some embodiments, the beads and/or the coating can be applied to the backer sheet 18 to give the wipe two textured surfaces, including embodiments where the composition of the beads and/or coating is different on each side of the wipe.
