Abstract
Method of producing a nonwoven material by hydroentangling a fiber mixture containing continuous filaments, e g meltblown and/or spunbond fibers, and natural fibers and/or synthetic staple fibers. The method is characterized by foamforming a fibrous web (14) of natural fibers and/or synthetic staple fibers and hydroentangling together the foamed fiber dispersion with the continuous filaments (11) for forming a composite material where the continuous filaments are well integrated with the rest of the fibers.
