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 composite material where the continous filaments are well integrated with the rest of the fibers.
L'invention concerne un procédé de production d'un matériau non-tissé, comprenant le liage par jet d'eau d'un mélange de fibres comprenant des filaments continus, p. ex. des fibres obtenues par fusion-soufflage et/ou filées-liées, et des fibres naturelles et/ou des fibres discontinues synthétiques, Ce procédé est caractérisé par la formation par mousse d'un voile (14) de fibres naturelles et/ou de fibres discontinues synthétiques et le liage par jet d'eau de la dispersion de fibres moussée avec les filaments (11) continus de manière à former un matériau composite dans lequel les filaments continus sont bien intégrés aux fibres restantes.
