Abstract: PURPOSE:A spinning process of combined filament yarns which specializes in the prevention of the filament cohesion and broken filament, and facilitates easy observation and separation of the yarns during the spinning process, by boring orifices of different shapes in a specific arrangement on the same spinneret, and by regulating the blowing direction of the cooling air.
