In particular, in a spinning bath, a bundle of spun filaments is first formed with a cross-sectional area corresponding to the distribution of holes in the spinneret and then brought together, usually by a finishing applicator or an entangling nozzle, to create smaller cross-sections. Make a thread-like bundle of area.

５，４７７に記載されている。A spinning process in which the filaments emerging from the spinneret are then first passed through a cooling zone where they are solidified and further passed through a conditioning zone in a spinning bath where they are heated to a temperature above the solidification temperature and below the melting point is Already in use today. Due to the friction between the spun filaments and the surrounding atmosphere, stresses are created in the filaments and partial stretching and orientation of the spun filaments also occurs during passage through the spinning bath. Such methods are described, for example, in DE-A-2,117,659,

行に伸びるように設計するのが好ましい。In a technically preferred embodiment, the internal diameter of the heating device decreases continuously over its entire length; ie, the heating device has a conical shape. Although this conical heating device is certainly more expensive to manufacture, it produces filaments of excellent quality and is very simple to operate. The inlet cross-sectional area of this preferred embodiment typically reduces the cross-sectional area of the spun filament bundle at that point by less than 50%, preferably by no more than 2
The size exceeds 0%. In this preferred embodiment,
In many cases, a size greater than 10% is sufficient, as the filament bundle progresses down with minimal lateral variation. The inner surfaces of the heating device are preferably designed such that they extend substantially parallel to the outer surface of the filament bundle.
