| Abstract: |
A cleaning tool is formed with a base, a woven backing fabric secured to the base, and a monofilament of resilient resin woven into the backing fabric so that lengths of the monofilament turn away from the plane of the backing fabric and extend outward from the backing fabric at a predetermined uniform angles to form a sparse pile of bristles stiff enough to stand free and resiliently self-supporting in a regular array for cleaning.
