Abstract
A method of producing a nonwoven material by hydroentangling a fiber mixture containing spunlaid filaments, natural fibers and synthetic staple fibers, wherein a first fibrous web (12) of natural fibers and at least 10% by fiber weight manmade staple fibers is wetlaid and hydroentangled in a first hydroentangling station (13), spunlaid filaments (16) are laid on top of the hydroentangled first fibrous web (12) and a second fibrous web (19) including natural fibers is wetlaid on top of said spunlaid filaments (16). The second fibrous web (19) is hydroentangled together with the spunlaid filaments (16) in a second hydroentangling station (20) and the combined webs are reversed and the first fibrous web (12) of natural fibers and manmade staple fiber is hydreoentagled together with the spunlaid filaments (16) in a third hydroentangling station (25).
