Abstract (en)
[origin: EP0285670A1] A high-density polyethylene three-dimensional net-like fiber (26) obtained by supplying a polymer to a melting zone (compression portion 13, metering portions 14 - 16) while melting the polymer by use of a heated screw extruder, supplying a solvent (CCl3F) to the molten polymer (supply port 18), preparing a polymer solution by mixing and dissolving them under a high pressure and discharging the polymer solution from a nozzle (24) disposed in the melting zone into a low-pressure zone. The fiber (26) is caused to impinge against a skirt portion (33) having a fiber rocking surface (34) and a buffer surface (35) and is expanded and opened to obtain a nonwoven fabric. This nonwoven fabric is excellent in strength, coverability and whiteness.
