Abstract: A method for producing a flushable hydroentangled moist wipe or hygiene tissue including the steps of: dry-, wet-, or foam-forming a fibrous web on a moving support, hydroentangling said fibrous web in a hydroentangling station to form a hydroentangled nonwoven web is disclosed. The moving support includes a plurality of protruding elongated elements protruding above the surface of the moving support. The protruding elements will produce weakenings in the hydroentangled web.

Abstract: A method for manufacturing a composite nonwoven web material includes extruding continuous filaments from a spinnerette, drawing the filaments by a slot attenuation unit to thin continuous filaments, forming a web of unbonded continuous filaments without thermobonds as the filaments are laid down, hydroentangling the web including continuous spunlaid filaments together with wet or foam formed short fibers including natural and/or synthetic fibers or staple fibers to integrate and mechanically bond and form a thermally unbonded composite nonwoven web material. A moist environment is created at the formation and lay down of the continuous filaments by the steps of laying down the filaments on an already wetted surface, keeping the width of the outlet of the slot attenuation unit open by more than 65 mm and adding liquid at the outlet of the slot attenuation unit.

Abstract: A flushable wipe or hygiene tissue includes a hydraulically entangled nonwoven material impregnated with a wetting composition, wherein the nonwoven material includes cellulose pulp fibers and/or manmade staple fibers. The nonwoven material includes disintegration elements having a projected surface area between 2 and 50 mm2 and an aspect ratio (L/D) between 1 and 10. The disintegration elements may be selected from the following group: botanical elements, paper containing a wet-strength agent, nonwoven material, and film material, and will result in a material that is more readily disintegratable when flushed in a sewer.
