Abstract
A dust mop features a dust collector layer made of electrostatically charged nonwoven fabric. The electrostatic charge (a) enables the dust collector to be detachably mounted to the mop head by electrostatic cling; and (b) improves the dust collecting ability of the dust collector.
Claims15
A dust mop comprising
- (a) a handle;
- (b) a mop head secured to one end of the handle and having a downwardly facing surface;
- and
- (c) an electrostatically charged thermoplastic nonwoven fabric detachably mounted on the downwardly-facing surface, said electrostatically charged nonwoven fabric having a persistent electrostatic charge imparted thereon by passing the fabric of fibers thereof through an electric field.

A mop for mopping a floor surface, comprising
- (a) an elongate handle;
- (b) a rigid head pivotally connected to one end of the handle and having a generally flat downwardly facing surface;
- (c) padding material mounted on the head to substantially cover the downwardly facing surface of said head, said padding material being in the form of a layer conformable to the floor surface;
- and
- (d) a disposable dust collector layer detachably mounted on the padding layer, said collector layer comprising an electrostatically charged thermoplastic nonwoven fabric having an inner surface in contact with the padding layer and an outer downwardly layer surface for collecting dust, the nonwoven fabric having fibers between 1 to 50 microns and carrying an electrostatic charge imparted by passing the nonwoven fabric or fibers thereof through an electrostatic field to impart an electrostatic charge thereto.
