実用に供し得るものが得られるに至っていない。(Prior art) Cooling gas is blown from one side of the melted and discharged polyester yarn, which has a circular or irregular cross-sectional shape as shown in FIGS. 2(a) and (b), to cool the discharged yarn anisotropically. Many attempts have been made to create crimped bulky polyester fibers by inducing a non-uniform structure in the yarns. However, simply anisotropically cooling the discharged polyester yarn does not develop sufficient crimp bulkiness.
We have not yet obtained anything that can be put to practical use.
そこで、第２図（ｃ）に示すようにポリエステル糸条を
中空断面にして、糸条の異方性を増大させ、捲縮嵩高性

用途に用いられているにすぎない。(Problems to be Solved by the Invention) As described above, when the polyester yarn is made hollow, the non-uniform structure of the yarn produced by anisotropic cooling is further promoted, and crimpability and bulkiness are improved. However, the bulkiness is still insufficient for use in clothing, and it is only used in limited applications such as futon cotton.

The inventors have discovered that the anisotropy of the yarn is significantly increased and the bulkiness is improved when the yarn is blown from this direction, and the present invention has been achieved.

ル繊維の製造法である。That is, in the present invention, when a polyester yarn is anisotropically cooled by blowing cooling gas from one side of the melted and discharged polyester yarn and then taken off to produce a bulky polyester fiber, the cross-sectional shape of the polyester yarn is changed into a concave portion. This is a method for producing a bulky polyester fiber, which is characterized in that it has a shape having a convex portion located on the opposite side thereof, and a cooling gas is blown from the convex portion side of the cross section.

ることができない。In the present invention, the cross-sectional shape of the melted and discharged polyester yarn is made into a shape having a concave part and a convex part located on the opposite side, as shown in FIGS. 1(a) and (b), and Cooling gas is blown from the convex side (that is, in the direction of arrow A in FIGS. 1(a) and 1(b)). By doing this, the structural anisotropy increases for the first time, and the bulkiness improves.
That is, even if cooling gas is blown in the direction of arrow B), or even if cooling gas is blown from the side of the convex part of the irregular cross-section thread, the irregular cross-sectional shape will cause the concave part to connect with the convex part located on the opposite side. If the shape is not the same, sufficient bulk cannot be achieved.

It is melted at 90°C and discharged from a spinneret each having 24 nozzles of various shapes to form the cross sections shown in Figures 1 (a), (b) and Figures 2 (a>, (b), and (C)). A planar yarn was spun. In this case, cooling gas (air) at 25°C was applied from the bottom surface of the spinneret at a speed of 3.0 m/sec in the direction shown in the following table between 70 and 130 km. In addition, the spun yarn was blown for 4,500 m by a roller heated to 70°C.
