リマーが多層構造状に複合した異型断面糸の紡糸口金装
置に関する。Description: FIELD OF THE INVENTION The present invention relates to a conjugate fiber spinneret, and more particularly to a spinneret having a modified cross section in which a plurality of polymers are compounded in a multilayer structure.

近い異形断面整流孔とすることもあった。(Prior Art) Conventionally, a conjugate fiber mainly has a circular cross section, but recently, a conjugate fiber having an irregular cross section has been increasing. Such a modified cross-section composite fiber spinneret rectifies the polymer composite flow obtained by the composite plate at the circular cross-section hole of the nozzle plate, and discharges it from the deformed cross-section orifice. Sometimes I did.

がかなり高くなる難点も有している。(Problems to be Solved by the Invention) In the case of a modified cross-section composite fiber, it is very difficult to discharge the polymer from the orifice of the nozzle plate without disturbing the composite shape of the composite flow formation in the composite plate. Generally, as a method, a composite flow in which a nozzle plate has a circular cross section and an orifice has a deformed cross section is often greatly disturbed in the process of deformation from a circular shape to a deformed shape. It is a major obstacle. Also, as in Japanese Patent Publication No. 54-43606, some attempts have been made to make the nozzle plate straightening hole a modified cross section close to the shape of the orifice.
The irregular rectification hole often causes a composite turbulence at a composite flow forming portion with the composite plate. Further, the irregular cross-section hole having a larger area and a longer length than the orifice also has a drawback in that the machining cost by electric discharge machining or the like becomes considerably high.
