ABSTRACT:
Methods are disclosed for treating fibrous webs with water jet streams. A water impermeable member is employed as a member for supporting the fibrous web in the water jet steam treatment. The jet treatment is carried out on a plurality of water impermeable rolls multistagedly and parallely arranged in order to provide effective draining treatment and effective entangling treatment of fibers after having been carried out on a water impermeable belt in order to transfer toward said rolls. The nonwoven fabrics obtained through the method do not substantially comprise openings and the fibers are intricately and firmly entangled in three dimensional direction.
