Method and the device in order the melt spinning does the many synthetic filament, to cool

摘要

This invention the melt spinning does the many synthetic filament, regards the device in order to cool. In this case, the filament first inside the annular device, is pushed out by the spinning nozzle (1), the ventilation diffuser (12) parallels next and is guided, is cooled lap it flows out lap from the surface of this ventilation diffuser to radial by the surface air style. According to this invention, as for the filament for solidifying, lap before the cooling by the surface air style, the addition cooling air style (7) with before, cooling is administered. The cooling air style before this (7), the raw ze it is closed the spinning nozzle (1) and the ventilation diffuser (12) with the cooling expedient which is arranged between by (6).
