The method of melt-blown forming polyurethane elastic nonwoven fabric is to feed thermoplastic polyurethane particles into a screw extruder after vacuum drying. The polyurethane particles are heated, melted and extruded into a melt. When the melt is removed from the die When the spinneret is extruded, it is blown by the high-pressure hot air flow on both sides of the spinneret. The melt is stretched to form an ultra-slender filament, cooled and condensed on the drum receiver, and self-adhesive...
