Abstract
A nonwoven composite cleaning pad is disclosed. The cleaning pad includes a first nonwoven layer having an absorbent surface. A second nonwoven layer is laminated to the first layer, and a plurality of abrasive polymer formations are provided on the exposed surface of the second layer.
Claims12
A nonwoven composite cleaning pad, comprising:
- a first nonwoven layer formed of a blend of polypropylene fibers and rayon fibers and having an inner surface and an absorbent outer surface;
- a second nonwoven layer formed of polyester spunbond continuous filaments, said second layer having an inner surface laminated to the inner surface of the first layer, the second layer defining an exposed outer surface;
- and
- a plurality of abrasive formations of thermoplastic polymer melt-adhered to the exposed outer surface of the second layer and defining discrete protuberances on the exposed surface of the second layer.

A nonwoven composite cleaning pad, comprising:
- a first nonwoven layer having a thermal bonded nonwoven structure formed of a blend of polypropylene fibers and rayon fibers, said first nonwoven layer having an inner surface and an absorbent outer surface;
- a second nonwoven layer having an inner surface disposed in opposing face-to-face relation to the inner surface of the first layer, the second layer formed of polyester spunbond continuous filaments and defining an exposed outer surface;
- an adhesive layer disposed between the opposing inner surfaces of said first and second nonwoven layers bonding the layers together to form a composite nonwoven structure;
- and
- a plurality of abrasive formations of thermoplastic polymer melt-adhered to and projecting from the exposed outer surface of the second nonwoven layer.

A method of manufacturing a nonwoven composite, comprising:
- providing a first nonwoven polymeric layer having an inner surface and an absorbent outer surface;
- laminating one surface of a second nonwoven polymeric layer to the inner surface of the first layer such that the second layer defines an exposed outer surface;
- and
- applying molten thermoplastic polymer directly to the exposed outer surface of the second layer in a plurality of discrete locations and allowing the molten polymer to solidify to form a plurality of melt-adhered abrasive polymer formations.
