摘要： The curved surface of a reduced part (2) has a connected surface of circular arcs (A) and (B) of radius R. The length (L) of the reduced part (2) is 30-60 % of max. length (L) of the nozzle and radius R is 13.0-18.0 m/m. This nozzle can produce filaments having min. difference of property between unit filaments by minimizing the resistance to the flow of polymer.
