Patent number: 9863073Abstract: A hydroentangled integrated composite nonwoven material, includes a mixture of randomized continuous filaments, splittable shortcut staple fibers, and optionally non-splittable staple fibers. The splittable fibers should be 3-16 mm long bicomponent fibers. Preferably there should be no thermal bonding points between the filaments. The nonwoven material has improved textile feeling and reduced two-sidedness. The continuous filaments should preferably be spunlaid filaments. Some of the staple fibers can be colored. A process of producing such a nonwoven material is disclosed.Type: GrantFiled: February 25, 2015Date of Patent: January 9, 2018Assignee: SCA HYGIENE PRODUCTS ABInventors: Anders Stralin, Hannu Ahoniemi, Lars Fingal, Mikael Strandqvist

Patent number: 9822487Abstract: A method for producing a flushable hydroentangled moist wipe or hygiene tissue includes 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. 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.Type: GrantFiled: April 8, 2014Date of Patent: November 21, 2017Assignee: SCA HYGIENE PRODUCTS ABInventors: Hannu Ahoniemi, Lars Fingal, Anders Strålin

Publication number: 20170027392Abstract: 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.Type: ApplicationFiled: April 8, 2014Publication date: February 2, 2017Inventors: Anders STRÅLIN, Hannu AHONIEMI, Lars FINGAL, Anna NIHLSTRAND

Publication number: 20150322606Abstract: 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.Type: ApplicationFiled: December 27, 2012Publication date: November 12, 2015Inventors: Anders STRÅLIN, Lars FINGAL, Kaveh TONDKAR
