发明名称 Cleaning and washing pad
摘要 An improved cleaning-and washing-pad material, which pad material comprises in combination: a soft natural or synthetic shearling sheet material forming one surface of the pad material and a tough, nylon-mesh material forming the other surface of the pad, the shearling material and the nylon material sewed together about the peripheral edges to form a cavity therein; and a soft, resilient, substantially open-cell, polyurethane or cellulose sponge material loosely inserted within the hollow cavity to provide body and bulk to the pad, whereby the improved cleaning- and washing-pad material presents a soft water-absorbent surface for washing and a tough scrubbing surface for cleaning purposes.
