2. Description of the Related Art Conventionally, polyester fibers are used for shirts,
It is used for various clothing applications such as blouses, and its application is expanding due to its general-purpose properties, but it is known to have less refreshing feeling (heat dissipation) than natural fiber and low water absorption. It can be applied by adding an oil agent, using a special polymer, or blending with natural fibers, mixed twisting, and mixed weaving.

Regarding the use of the special oil agent, the washing durability is inferior due to the method, and a curing agent is required to improve the durability, but it has a drawback that the texture becomes hard. On the other hand, as a method of obtaining water absorption performance by polymer modification, a method of using a copolymer with a hydrophilic component such as a third component containing sodium sulfonate in the polymer is considered, but in any case, its function is to absorb water. I can't say that. Further, a method has been proposed in which particles are dispersed in a polymer, and the particles are extracted with a chemical agent to impart water-absorbing performance utilizing extraction marks left on the fiber surface, but the water-absorbing performance is still insufficient.

Further, in the cross section of the polyester fiber of the present invention, the minimum value of the interval between adjacent protrusions is 10 to 20 μm, preferably 12 to 28 μm. If the minimum distance between adjacent protrusions is less than 10 microns, the capillaries are too small to be water moving capillaries. On the other hand, when it exceeds 20 microns, there is a problem that fibrillation is likely to occur due to abrasion of the protrusions when worn as clothing, for example. The point is that there is at least one combination of protrusions with a spacing between adjacent protrusions of 10 to 20 microns.
It suffices that these exist, and the protrusion interval exceeding 10 to 20 microns does not prevent the existence of other protrusions.

In the cross section of the fiber of the present invention, the depth of the valley formed between adjacent protrusions having the above-mentioned minimum distance of 10 to 20 microns is 10 to 20 microns, preferably 12 to 10 microns.
It is set to 28 microns. The depth of such valley is 10
If it is less than micron, there is a problem that the capillary is too small to be a capillary for moving water. On the other hand, if it exceeds 20 micron, for example, fibrillation due to abrasion of protrusions when worn as clothing is not possible. There is an easy problem.

The polyester fiber of the present invention can be produced by spinning a polyester polymer having a melt viscosity of 2000 poise or more and a titanium oxide content of 1 wt% or more by ordinary melt spinning. As the polymer discharge hole of the die, a combination of slits having a predetermined shape according to the sectional shape is used. The unstretched yarn obtained by spinning is made to have a uniform tow denier, and the number of the unstretched yarns is made uniform. The unstretched yarn is heat-stretched at an appropriate draw ratio suitable for the spinning speed, and after crimping, it is made into a tow product. Depending on the situation, stretching may be followed by heat treatment for constant length, relaxation, and limited shrinkage, and heat treatment for relaxation after crimping may be performed, and the selection can be made according to the strength and elongation characteristics.

In the method for producing a polyester spun yarn of the present invention, a tow comprising the above-mentioned polyester fiber of the present invention is used, and this is made into a spun yarn by stretch-spread spinning. When using a general carded spinning card machine, it is difficult to obtain a spun yarn with a fine denier long fiber length, and in order to use a card, it is necessary to use a fine fiber length, and it has a substantial water absorption property.

Further, in the method of the present invention, at the time of drafting,
The fiber length is cut to 100 mm or more, preferably 110 mm or more. The fiber length means an average fiber length. When the fiber length is 100 mm or less, the length of the slit is short, so that the water movement due to the capillary phenomenon is not performed and the water absorption performance is extremely lowered, so that it is difficult to obtain the water absorption effect aimed at by the present invention. Generally, from the viewpoint of yarn formation by spinning, the fiber length is preferably 150 mm or less.

It was packed after application. The packed tow was set in a tow reactor, and a checkout test was performed under normal conditions to prepare a sliver. The stretchability was evaluated mainly in the main cut zone.
