Claims (9)

A method of applying a plurality of nanoparticles to a surface, said method comprising the steps of: (a) providing a surface, wherein said surface is a portion of a disposable absorbent article; (b) providing a composition comprising a plurality of nanoparticles; (c) printing said nanoparticles onto said surface using an inkjet printer, and (d) prior to or concurrent with step (c) carrying our a surface energy treatment of said surface.
The method of claim 1 wherein said disposable absorbent article is selected from the group consisting of diapers and catamenial products.
The method of claim 1 wherein said surface is selected from the group consisting of topsheets, acquisition layers, distribution layers, wicking layers, storage layers, absorbent cores, absorbent core wraps containment structures and combinations thereof.
The method of claim 3 wherein the ink jet printer comprises at least one spray nozzle, and said at least one spray nozzle is movable with respect to said surface.
The method of claim 1 wherein said nanoparticles comprise photoactive nanoparticles.
The method of claim 1 wherein said nanoparticles comprise non-photoactive nanoparticles.
The method of claim 1 wherein said treatment is selected from the group consisting of: corona discharge treatment; plasma treatment; UV radiation; ion beam treatment; electron beam treatment; and laser treatment.
The method of claim 1 wherein said composition further comprises a surfactant selected from the group consisting of anionic surfactants, nonionic surfactants, and mixtures thereof.
The method of claim 1 wherein said nanoparticles are selected from the group consisting of natural clays, synthetic clays, and inorganic metal oxides.

Description

The present invention relates to coating compositions, methods and articles of manufacture comprising a nanoparticle system or employing same to impart surface modifying benefits for all types of soft surfaces, and in some cases, hard surfaces.

Inorganic particulates, such as, clays, silicates, and alumina have been widely used in combination with adjunct detergent and laundry compounds to impart some form of antistatic control and/or fabric softening benefit.

One approach taken in the prior art discloses anti-static benefits using inorganic particulates. Patents describing such uses include U.S. Pat. No. 3,594,212 and U.S. Pat. No. 3,862,058.

The benefit of fabric softening is widely disclosed in the prior art. Patents describing such uses include: U.S. Pat. No. 3,886,075; U.S. Pat. No. 4,806,253; U.S. Pat. No. 4,885,101; U.S. Pat. No. 5,004,556; U.S. Pat. No. 5,019,292; U.S. Pat. No. 5,209,857; and U.S. Pat. No. 5,721,205.

It is generally well known that inorganic particulates can be used in the cleaning, freshening and deodorizing of certain types of textiles, such as carpets. See, for example, U.S. Pat. No. 3,716,488 (Stevens J & Co); U.S. Pat. No. 3,736,259 (Colgate Pomalive); U.S. Pat. No. 4,035,148 (P&G); U.S. Pat. No. 4,090,974 (FMC); U.S. Pat. No. 4,566,980 (Creative Products); U.S. Pat. No. 4,581,385. and U.S. Pat. No. 4,873,000 (Sterling Drug). In practice, the clays used in these cleaning compositions have particle sizes between 10-60 μm (10,000-60,000 nanometers).
