US 8,263,183 B2 · Cleaning device

Abstract

This invention relates to a cleaning device comprising a cleaning composition and a substrate. The cleaning composition comprises an absorbent particulate, a binding agent, and optionally, a thickening agent. The cleaning composition may be applied to a substrate, such as a textile substrate, by applying the composition to at least one portion of the surface of the substrate or by incorporating the composition throughout the substrate. The absorbent particulate generally exhibits a high affinity for particles, color, grease, oil, and other staining materials and is a soft material which allows for gentle cleaning of most surfaces without detrimentally abrading and scratching soiled surfaces. The absorbent particulate also serves as an indicator providing a visual cue of its cleaning efficacy and may be used in either a wet or dry state.

Dependent claims

A method for manufacturing a cleaning device, said method comprising the steps of:

(a) providing a substrate having a first surface and a second surface;
(b) applying a formulation to at least one portion of said first surface of said substrate wherein said formulation is comprised of:
(i) an absorbent particulate, wherein said absorbent particulate has an average particle size of from about 1 to about 300 microns in diameter and an oil absorption value of at least 40;
(ii) a binding agent, wherein the ratio of binding agent to absorbent particulate is between about 0:1 and about 6:1 by weight;
and
(iii) optionally, a thickening agent, wherein the thickening agent is present in an amount to adjust the viscosity of the formulation to between about 100 cps and about 10,000 cps;
wherein the step of applying the formulation is accomplished by screenprinting or scatter coating;
and
(c) curing said treated substrate.
