石油系又は石炭系ピツチを溶融状態で紡糸する
ノズルに於いて、ノズル本体材質を熱伝導が良く
、溶融ピツチに濡れる金属又は合金にすると共に
、ノズル端面に於いて、ノズル孔の最狭孔径より
も大きく、かつ最大径が１．０mm以下の領域外を
溶融ピツチに濡れない材質にて形成したことを特
徴とする紡糸用ノズル。 In a nozzle that spins petroleum-based or coal-based pitch in a molten state, the material of the nozzle body is a metal or alloy that has good heat conductivity and can be wetted by the molten pitch, and the nozzle end face has a diameter that is smaller than the narrowest hole diameter of the nozzle hole. 1. A spinning nozzle characterized in that the outside of the area having a maximum diameter of 1.0 mm or less is made of a material that does not get wet by the molten pitch.
