Abstract

PURPOSE: To manufacture a superfine fiber web of good quality free from polymer shots from a condensation polymer, by means of a die, wherein two fluid slits formed from a die nose and a lip plate, and a die nose tip is located inside the tips of lip plates.
CONSTITUTION: A melt blowing die, wherein the die nose 2 has a plurality of die orifices 1 at the tip A of the isosceles triangle cross-section and the two fluid slits 4 formed by the lip plates 3 along the orifice row. The die nose tip A is located inside the tips B of the lip plates 3 by the distance, 0W0.4 mm, and the die orifice diameter r is 0.15W0.5 mm. The minimum distance X between the extension D of the orifice periphery line C and the tip B of the lip plate 3 in the cross-section cut in the long direction of the orifice at the maximum orifice diameter is expressed by the following relation: r/10≤X≤4/5.r.
