Abstract

Claims (20)

1. A method of making a nonwoven dual sided home care cleaning article comprising the steps of:

a. providing a three-dimensionally imaged nonwoven fabric comprised of an absorbent precursor web, and a meltblown precursor web comprising filaments in the range of 5-50 microns, wherein said webs are hydroentangled on a three-dimensional image transfer device to form said cleaning article; and

b. a cleansing composition comprising an effective amount of a cleansing surfactant, said cleansing composition being coated onto and/or impregnated into said fabric to the extent of from 50% to 500% by weight of the fabric.

2. A method of making a nonwoven dual sided home care cleaning article as in claim 1 , wherein said cleansing composition is an aqueous or non-aqueous composition.

3. A method of making a nonwoven dual sided home care cleaning article as in claim 1 , wherein said cleansing composition includes one or more compositions selected from the group consisting of alkylpolysaccharides, alkyl ethoxylates, alkyl sulfonates, organic solvents, mono- or polycarboxylic acids, odor control agents, peroxides, hydrogen peroxides, thickening polymers, aqueous solvent systems, suds suppressors, perfumes or fragrances, detergent adjuvants, buffers, preservatives, antibacterial agents, colorants, bleaching agents, abrasive compounds, degreasers, chelants, enzymes, hydrotropes, and the combinations thereof.

4. A method of making a nonwoven dual sided personal care cleaning article comprising the steps of:

a. providing a three-dimensionally imaged nonwoven fabric comprised of an absorbent precursor web, and a meltblown precursor web comprising filaments in the range of 5-50 microns, wherein said webs are hydroentangled on a three-dimensional image transfer device to form said cleaning article; and

b. a cleansing composition comprising an effective amount of a cleansing surfactant, said cleansing composition being coated onto or impregnated into said fabric to the extent of from 50% to 500% by weight of the fabric.

5. A method of making a nonwoven dual sided personal care cleaning article as in claim 4 , wherein said cleansing composition is an aqueous or non-aqueous composition.

6. A method of making a nonwoven dual sided personal care cleaning article as in claim 4 , wherein said cleansing composition includes one or more compositions selected from the group consisting of abrasives, anti-acne agents, anticaking agents, antioxidants, binders, biological additives, bulking agents, chelating agents, chemical additives, natural additives, colorants, vitamins, cosmetic astringents, cosmetic biocides, denaturants, drug astringents, emulsifiers, external analgesics, film formers, fragrance components, humectants, emollients, opacifying agents, plasticizers, preservatives, propellants, reducing agents, skin bleaching agents, skin-conditioning agents, skin protectants, solvents, foam boosters, hydrotropes, solubilizing agents, suspending agents, sunscreen agents, ultraviolet light absorbers, viscosity increasing agents, and the combinations thereof.

7. A method of making a nonwoven dual sided industrial cleaning article comprising the steps of:

a. providing a three-dimensionally imaged nonwoven fabric comprised of an absorbent precursor web, and a meltblown precursor web comprising filaments in the range of 5-50 microns, wherein said webs are hydroentangled on a three-dimensional image transfer device to form said cleaning article; and

b. a cleansing composition comprising an effective amount of a cleansing surfactant, said cleansing composition being coated onto and/or impregnated into said fabric to the extent of from 50% to 500% by weight of the fabric.

8. A method of making a nonwoven dual sided industrial cleaning article as in claim 7 , wherein said cleansing composition is an aqueous or non-aqueous composition.

9. A method of making a nonwoven dual sided industrial cleaning article as in claim 7 , wherein said cleansing composition includes one or more compositions selected from the group consisting of oils, paraffinic solvents, polybutylenes, polyisobutylenes, polyalphaolefins, toluenes, sequestering agents, corrosion inhibitors, abrasives, petroleum distillates, and the combinations thereof.

10. A method of making a nonwoven dual sided medical cleaning article comprising the steps of:

a. providing a three-dimensionally imaged nonwoven fabric comprised of an absorbent precursor web, and a meltblown precursor web comprising filaments in the range of 5-50 microns, wherein said webs are hydroentangled on a three-dimensional image transfer device to form said cleaning article; and

b. a cleansing composition comprising an effective amount of a cleansing surfactant, said cleansing composition being coated onto and/or impregnated into said fabric to the extent of from 50% to 500% by weight of the fabric.

11. A method of making a nonwoven dual sided personal care cleaning article as in claim 10 , wherein said cleansing composition is an aqueous or non-aqueous composition.

12. A method of making a nonwoven dual sided personal care cleaning article as in claim 10 , wherein said cleansing composition includes one or more compositions selected from the group consisting of iodines, alcohols, biocides, abrasives, metallic materials, bacteriostatic complexes, bactericidal complexes, and the combinations thereof.
