摘要
A three-dimensional plexifilamentary fiber (26) of a high-density polyethylene group obtained by supplying a polymer to a dissolving area in a state such that the polymer is melted by a heated screw extruder (compressing zone 13, metering zone 14 to 16), supplying a solvent (CCl3F) into the melted polymer (feed opening 18), mixing and dissolving the polymer and the solvent to make a polymer solution, and extruding the polymer solution from a nozzle (24 in FIG. 24 ) arranged in the dissolving area into a low pressure area. A nonwoven fabric is obtained through a process in which the fiber (26) is spread by striking the fiber against a skirt portion (33) having a fiber swinging face (34) and a cushioning face (35), and this nonwoven fabric has an excellent strength, covering property, and whiteness.
