Title: Acetate filament yarn winding method
Inventor: SAWADA FUMIO
IPC: D01D5/04
Filed: 1989-02-21
Abstract: PURPOSE:To make it possible to reduce the cost largely by using a winding tube provided with plural through holes on the surface of a yarn winding part at the time of spinning and winding acetate filament yarn by a dry spinning method. CONSTITUTION:In spinning and winding acetate filament yarn by a dry spinning method, a winding tube provided with plural through holes on the surface of its yarn winding part is used. With this structure, the volatilization of solvent remaining at an inner layer is largely promoted so as to shorten the time for decreasing it until it reaches the practically no-problem level, the contraction difference of the filament before and after its tail shifting is minimized, and the winding tube can be used with no restriction on its shelf time without generating any green machine faults such as green break. Accordingly, the cheese package of acetate filament yarn after dry spinning can be thrown into the after-process of an air jet room and the like without conserving it for a long time, and thus the cost can be largely reduced.
