Abstract
The invention refers to a disposable dust-cloth. The cloth is part of a dry natural fiber material that is a soft open-pored puffy pulp paper, in colors ranging from light to white, with a filler fraction of less than 10%. The paper is impregnated with a biodegradable wax which has a hardness that prevents its shearing off from the natural fiber material. The wax is a natural wax of plant or animal origin, preferably carnauba or bees waxes, or a synthetic or a chemically modified wax, preferably a paraffin, oxidized polyethylene wax or hydrogenized jojoba oil.
Claims7
A fully biodegradable dust-cloth for single use consisting of a natural wax impregnated, absorbent, cellulose, open-pored, fluffy, non-woven felt with a filler fraction of less than 10%, a water content of substantially zero at room temperature, a surface weight of 35-60 g/m.sup.2 and a wax content of 25-50 g/m.sup.2, said wax having a melting point in the range of 60-85 degrees C. and a hardness sufficient to prevent its removal from the fiber material during use in dusting, thereby to prevent leaving a film of wax or moisture when used to remove dust from a hard surface.
