Abstract
A non-woven fabric is formed from a reticulated foam combined with at least one layer of a nonwoven web. This unbonded composite fabric is then entangled together by passing it under jets of water, which are under high pressure. The resulting fabric structure has stiff foam protrusions, exiting the nonwoven fabric to function as bristles.
