Claims (1)

아크릴로니트릴 중합체와 물의 균질한 단상(單相) 용융체를 방사구를 통하여, 포화상태이며 초기 압출물로부터의 물의 이탈을 조절하고 이 압출물을 가소성의 상태로 유지하는 압력 및 온도로 유지되는 증기압 고형역으로 직접 압출한 후, 이 앞출물이 고형역내에 남아있는 동안 상기 압출물을 연신하는 공정으로 이루어지며, 고체 삽입체에 의해 부분적으로 가로 막혀진 방사공을 가진 방사구를 사용함으로써 중공형(中空形) 및 개구형(開口形) 구조를 가진 섬유를 제조함을 특징으로 하는 개량된 단면 형태를 갖는 아크릴로니트릴 중합체 섬유의 제조방법.Vapor pressure maintained at a pressure and temperature to maintain the homogeneous single-phase melt of the acrylonitrile polymer and water through a spinneret, saturated and to control the escape of water from the initial extrudate and to keep the extrudate in a plastic state After extruding directly into the solid region, it consists of a process of stretching the extrudate while the extrudate remains in the solid region, and is hollow by using a spinneret with a spinneret partially blocked by a solid insert. A method for producing an acrylonitrile polymer fiber having an improved cross-sectional shape, characterized by manufacturing fibers having a (中空形) and an open-type structure. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: Disclosure is based on the original application.
