Method for manufacturing polyurethane elastic non-woven fabric by melt-blown web

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 to form a polyurethane elastic nonwoven fabric.
The method of melt-blown forming polyurethane elastic non-woven fabric is not only simple in equipment, short in process flow, and low in investment, but also has fine fiber fineness, fluffy structure, large specific surface area, and good flexibility.
