Claims (7)
前記吐出孔より吐出されるポリマーを挟んで対向するように、前記リップの下面を起点に、ポリマー吐出方向に延在する一対の拡幅壁面を配し、
前記一対の拡幅壁面の成す角度αが６０°≦α≦１２０°の範囲であり、且つ、
前記リップの下面と前記ギャップを形成する壁面の交点をＸ、前記リップの下面と前記拡幅壁面の交点をＹとしたとき、対向する交点Ｘ間の間隔Ｐと、対向する交点Ｙ間の間隔Ｈとが、２≦Ｈ／Ｐ≦１５の範囲である
ことを特徴とする不織布の製造装置。 A slit is provided between a nozzle having an ejection hole group in which ejection holes for ejecting a molten polymer are arranged in a row and a pair of lips arranged to face each other with the ejection hole group of the nozzle interposed therebetween. A device for manufacturing a nonwoven fabric by blowing gas from the gap against the polymer discharged from the discharge hole,
a pair of widened wall surfaces extending in the direction of polymer discharge from the lower surface of the lip so as to face each other across the polymer discharged from the discharge hole;
The angle α formed by the pair of widening wall surfaces is in the range of 60°≦α≦120°, and
When the intersection of the lower surface of the lip and the wall surface forming the gap is X, and the intersection of the lower surface of the lip and the widened wall surface is Y, the distance P between the opposing intersections X and the distance H between the opposing intersections Y is in the range of 2≦H/P≦15.
