A substantially flexible, dry matrix, which contains not more than about 3% moisture at room temperature, is impregnated with a water free treatment mixture containing a lipid and a surfactant. In a preferred embodiment, the mixture includes a glycol, a surfactant and a lipid emollient, lubricant, medicament or skin protectant. Methods of manufacturing and using the impregnated matrices are also taught.

Impregnated matrix and method for making same

A disposable waste containment composite is disclosed for fabrication into baby diapers, incontinent briefs, feminine hygiene pads, incontinent under pads and sheets, wound dressings and the like. The composite is formed from a liquid permeable topsheet, an absorbent core and an impermeable backing sheet unified by the use of adhesives, heat and pressure, ultra sonic welding and the like. The composite is characterized in that its topsheet has been treated with a non-aqueous composition comprising propylene glycol, a non-water soluble protectant, and a surface active agent. The treatment composition can also preferably include an emollient an anti-odorant, a healing agent or the like. A unique feature of the treatment is that the non-water soluble components do not restrict or interfere with the passage of bodily waste into the absorbent core. The top sheet so treated delivers in use the protectant and other agents such as the healing agent, to the surface of the skin so that when the fabricated article is employed, the incidence of contact dermatitis, skin irritations, maceration and pressure ulcers are reduced. In addition, the use of this unique topsheet treatment reduces friction which, along with the other benefits, can virtually eliminate the need for separately using medicated creams, ointments or powders.

A method of making a substantially flexible dry matrix capable of removing dust, organic film or both, to which no water has been added other than that naturally present therein, said matrix possessing anti-static properties and being capable of removing dust and retaining said dust on the surface threreof comprising uniformly contacting said which comprises passing a continuous line of a matrix material comprising (a) natural or synthetic woven, non-woven or knitted fibers, or (b) flexible foam material or combinations thereof with between an engraved roll and a smooth roll, said engraved roll containing a non aqueous treatment solution on the surface thereof; coating said matrix material with an effective amount of a non-aqueous treatment solution sufficient to allow said matrix to retain its substantially flexible dry characteristics and to remove said dust and organic film; said non-aqueous treatment solution comprising by weight between about 25% and 75% of at least one glycol compound and between about 0.2% and 60% of a cationic surfactant.

Method of preparing a substantially dry cleaning wipe

A method for making a substantially flexible dry matrix and the result and article capable of cleaning a surface by removing dust and/or organic film and rendering the surface substantially static-free, suitable for use as a garment, air filter or mat, comprising a matrix comprising natural or synthetic, woven, non-woven or knitted fibers, or a flexible foam material, said matrix having been uniformly coated with an amount of treatment solution sufficient to allow said matrix to retain its substantially dry characteristics, said solution comprising between about 25% and 75% of at least one glycol compound, between about 0.2% and 60% of a cationic surfactant, an antimicrobial compound and optionally up to about 45% of a nonionic surfactant may be added to the treatment solution. When removing organic film, the wipe is contacted with water and used to wash the surface, and can then be rung out and used to wipe the surface dry.

Method of making a dry antimicrobial fabric

A substantially flexible dry wipe capable of cleaning a surface by removing dust and/or organic film and rendering the surface substantially static-free comprising a matrix comprising natural or synthetic, woven, non-woven or knitted fibers, or a flexible foam material, said matrix having been uniformly coated with an amount of treatment solution sufficient to allow said matrix to retain its substantially dry characteristics, said solution comprising between about 25% and 75% of at least one glycol compound, between about 0.2% and 60% of a cationic surfactant, and optionally up to about 45% of a nonionic surfactant may be added to the treatment solution. When removing organic film, the wipe is contacted with water and used to wash the surface, and can then be wrung out and used to wipe the surface dry.
