Abstract: A cleaning cloth is formed by treating a fibrous material with a composition to which solid particles adhere. The composition includes a tackifier, a pressure-sensitive adhesive and a slip agent. The tackifier is 45-77 wt. %, the pressure-sensitive adhesive is 20-40 wt. % and the slip agent is 3-15 wt. % of the composition. Other ingredients, such an antifoam agent and a pH control, can also be added. The tackifier is an unsaturated, low-molecular-weight resin having low vapor pressure and a molecular weight of<30,000, e.g., polybutene, polyisobutylene, polyhexene or an unsaturated alkyl. The preferred tackifier is polybutene. The pressure-sensitive adhesive is acrylic, styrene butadiene rubber, vinyl acetate or other suitable pressure-sensitive compounds. The slip agent is a high-melting-point wax or a natural fatty acid ester. The preferred slip agent is ammonium stearate.

Abstract: A non-woven cleaning cloth preferably made by the hydro-entanglement process and impregnated with a pressure sensitive adhesive and a tackifier. This Abstract shall not be construed to limit the scope of the invention, as defined by the claims, or of the specification.

Abstract: An apparatus and related process for entangling a staple fibrous web which employs divergent fluid jets. The web is advanced through an entangling station on a conveying means which supports an entangling member having a symmetrical pattern of fluid pervious void areas. The divergent jet sprays which are disposed above the entangling member direct a continuous curtain of fluid onto the web, coacting with the entangling member to entangle web fibers into a coherent lattice structure. The divergent jet sprays are provided by nozzles having wide orifice diameters which accommodate less complex fluid recirculation and filtration systems than employed in prior art columnar jet processes.

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.
