(2') An undrawn yarn with a shrinkage ratio SHD of 10% or less under dry heat at 160°C, obtained by oriented crystallization spinning of polyester containing ethylene terephthalate as a main component, was drawn at a first-stage drawing temperature of 70 to 150''. C, 75-95% of the stretching ratio at break
After the second stage, the fibers are stretched at a stretching ratio of 200°C to the melting point and a stretching ratio of 90 to 98% of the breaking stretching ratio, and the fibers are reduced by using a bath agent or a decomposing agent for the fibers. This is a method for producing polyester synthetic fibers.

More preferably, by providing the fiber surface with 5 or more, preferably 20 or more fine recesses per square micron, it is possible to have a deep color tone while having high modulus. If the number is less than 5, the bathochromic effect disappears, which is not preferable. If there are more than 1000 pieces, it will feel slimy, which is not good. The second requirement is that the fiber surface has a fine striation structure of irregular width, and the fine striation fI! # is 1 micron or more in the fiber axis direction, preferably 1 and 3
If it does not have a length of μ or more, especially 5 μ or more, it is not preferable because the water absorption and release properties, which are one of the measures for dry touch feel and comfort, will be reduced. Although the width of the fine striations is not constant and has an irregular width, a width of 1 μm or less is preferable because it has excellent water absorption and discharge properties. The preferred number of fine striations is 1 or more, preferably 3 or more, especially 5 or more per 100 square microns on the surface of the 11R pheasant, as this improves dry touch and has excellent water absorption and release properties. It has the effect of reducing the feeling of stuffiness when you use it.

The structure is fixed by stretching and heat setting at a stretching ratio of 0 to 98%. If stretching is performed in multiple stages of three or more stages, the structure may be destroyed, resulting in lower strength, lower modulus, and lower melting point, so carefully set the stretching conditions to provide the necessary properties depending on the application. There is a need to. In addition, the stretching temperature is
There is a need to maintain a temperature that does not produce 1 stone. The drawing may be carried out by continuously drawing the yarn taken during spinning, or by winding the drawn yarn in one stretch and then drawing it.
