Abstract:
1. A method of producing a nonwoven material by hydroentangling a fiber mixture containing spunlaid filaments, wood pulp fibers and synthetic staple fibers, the method comprising: wetlaying a first fibrous web of wood pulp fibers and at least 10% by fiber weight of manmade staple fibers, hydroentangling said first fibrous web in a first hydroentangling station, laying spunlaid filaments on top of said hydroentangled first fibrous web, wetlaying a second fibrous web comprising wood pulp fibers on top of said spunlaid filaments and hydroentangling together said second fibrous web with the spunlaid filaments in a second hydroentangling station, thus forming a combined web comprising said first and second fibrous webs and said spunlaid filaments, and reversing said combined web and hydroentangling together the first fibrous web of wood pulp fibers and manmade staple fiber with the spunlaid filaments in a third hydroentangling station.
