摘要:
An abrasive cleaning apparatus (10) has an integral drum (D) formed of inner (26) and outer (36) layers of resilient materials and a rigid layer in between. Holes are formed through drum (D) in a spiral pattern around the drum. A wire (W) is engaged in each hole (H), the wire (W) having opposing ends and three bends. One end of wire (W) is inside drum (D) with an adjacent portion lying circumferentially on an inner surface (30) of drum (D). A portion of wire (W) outside drum (D) is aligned in an opposite circumferential direction as the portion of wire (W) inside drum (D). A retaining cylinder (R) sandwiches an end of wire (W) inside drum (D) between itself and an inside surface of drum (D), holding wire (W) stable. The end of wire (W) inside drum (D) is in close proximity to ends of adjacent wires, which inhibits rotation of a wire in its hole in the drum.
摘要:
The present invention relates to a cleaning implement based on melamine-formaldehyde foam comprising hollow microspheres, wherein said hollow microspheres have a median particle diameter (D50, volume averaged, Malvern, Fraunhofer diffraction) in the range from 260 µm to 490 µm, and wherein the hollow microsphere are at least partly filled with a benefit agent. Additionally the present invention encompasses a method for cleaning a hard surface with a cleaning implement according to the present invention.
