Abstract
Sheets capable of developing a positive electostatic charge are used for a variety of surface cleaning operations. Polyester fabric, non-woven and chemically bonded with an acrylic latex is used to dust surfaces, to clean clothes, furniture and carpets. A light solvent such as isopropanol can be used with the sheets to loosen gummy soils. In one mode, the sheets are used in a hot air clothes dryer to remove soils and detritus from garments. Processes for cleaning a variety of fabric and hard surfaces are conducted using the sheets.
