PVCの溶融紡糸に関する研究

第7報 PVCの押し出し紡糸について

We made two small extruders-having fine screw diameter; 8mm and 13mm, and studied on the spinning by extrusion of plasticised and unplasticised polyvinyl chloride.
We succeeded to prepare fine denier filaments by equipping the extruder with heating tube.
This spinning process is discussed and the authors suggest that the drawing effect of filament in molton state would have almost the same effect as in melt spinning not using a nozle.
