Abstract
A cleaning sheet for cleaning and removing particles from a surface is disclosed. The sheet includes a particle retention layer including an electret material for collecting and retaining the particles. The sheet also includes an outer layer covering at least a portion of the particle retention layer. The outer layer comprises a low dust retention material and includes a surface having a plurality of apertures formed therethrough.
Claims28
A cleaning sheet for cleaning and removing particles from a surface, said sheet comprising:
- a particle retention layer including an electret material for collecting and retaining the particles;
- and
- an outer layer covering at least a portion of the particle retention layer, the outer layer comprising a low dust retention material and including a surface having a plurality of apertures formed therethrough, wherein the apertures have a cross-sectional dimension of at least about 1 mm2.
A cleaning utensil for collecting and retaining debris comprising
- a cleaning head;
- a cleaning sheet adapted for coupling to the head including:
- a particle retention layer including an electret material;
- and
- an outer layer covering at least a portion of the particle retention layer, the outer layer including a plurality of apertures having a cross-sectional dimension of at least 1.0 mm2 and formed from a low dust retention material.
A kit for cleaning surfaces and collecting and retaining debris comprising
- a cleaning head;
- a cleaning sheet adapted for coupling to the head including:
- a particle retention layer including an electret material;
- and
- an outer layer covering at least a portion of the particle retention layer;
- wherein the outer layer includes a plurality of apertures therethrough and is formed from a low dust retention material.
A method of cleaning a surface comprising:
- contacting the surface with a cleaning sheet including:
- a particle retention layer including electret material;
- and
- an outer layer covering at least a portion of the particle retention layer;
- wherein the outer layer includes a plurality of apertures therethrough and is formed from a low dust retention material.
