Abstract:
A spinning die for producing ultrafine fiber nonwoven fabric is made miniaturized and its productivity thereof is enhanced. The spinning die has a substantial cuboid shape and a plurality of nozzle holes is disposed in a longitudinal direction. A slit for jetting hot air is disposed only in one side of the nozzle holes. Thermoplastic polymer is melt blown from the nozzle of the spinning die to obtain ultrafine fibers. Hot air is jetted from the slit disposed at only one side of the nozzle holes. The result is that the ultrafine fibers melt blown in a direction inclined with respect to an axis direction of the nozzle. The blown ultrafine fibers are accumulated by sucking to downward to obtain ultrafine fiber nonwoven fabric.

Claim (Index 2):
The method for producing ultrafine fiber nonwoven fabric according to  claim 1 , wherein the slit is provided in either a right side or a left side of a line of the nozzle holes.
