Abstract (en)
[origin: WO0122858A1] Layered cleaning sheets (10, 30, 50), including a layer of electret material (12, 32, 52) and a layer of absorbent material (14, 34, 54), are described. The electret material layer is particularly suitable for removing particulate materials, such as, but not limited to dust and soil, and is at least partially or semi-impervious to liquid materials. The absorbent material layer is particularly suitable for absorbing relatively large amounts of liquid materials, such as, but not limited to water. Additional layers, such as, but not limited to adhesives (36, 58, 60) and barriers (56) can be interposed between the electret and absorbent material layers in order to provide enhanced durability and imperviousness to liquid materials.
