- the first filament may have a fineness of 3 to 7 deniers.
- the fineness of the first filament is less than 3 deniers, cutting occurs a lot and the spinning workability is lowered. If the filament is more than 7 deniers, the filament agglomeration occurs due to lack of cooling, and the spinning workability is lowered and the continuous nonwoven web is formed. It is difficult to maintain uniformity in
- FIG. 1 An example of the cross section of the first filament is as shown in FIG.
- the cross section yarn of the first filament is controlled by adjusting the length of the width (and arm) of the cross section of the V-shaped cross section at the nozzle in which the polyester polymer is discharged.
