It is. In addition, a ring-opening and curing catalyst for the epoxy compound, such as amines, can be applied simultaneously or separately with the epoxy compound to promote the ring-opening polymerization-curing reaction of the epoxy compound in a heat treatment process that is carried out simultaneously with or subsequent to the stretching.

いた。As mentioned above, in the technique of applying an epoxy compound to polyester fibers and subsequently heat-treating them, the epoxy compound adheres to the surface of the heating roller used for the heat treatment, and the resin of the EVO 4 copolymer is deposited on the surface of the heating roller. A film is formed. When polyester fibers are wound around the heated L-1-la on which this resin film has been formed and subjected to hot stretching or heat treatment, the heating [1-la] changes the frictional resistance between the polyester fiber and the polyester fibers. The thermal conductivity of the polyester fiber changes, and the physical properties of the polyester fiber, especially its strength, elongation, and adhesion to rubber, change by 1! This method has the disadvantage that the frequency of cutting of the entire thread increases. Furthermore, if it becomes clear that a resin film has formed on the surface of the heating roller, resulting in a decrease in thermal conductivity, the work of replacing the heating roller will have to be canceled, and operations will have to be interrupted during this period, resulting in poor operability. However, it has the drawbacks of lowering the temperature and requiring work to remove the resin film.

The drawing shows an example of the present invention, and is a partially schematic front view of a drawing and winding device for polyester fiber; The yarn Y1 made of poly 1 stellate fiber is stretched in the direction of arrow a from a spinning process (not shown), for example. Finally, the drawing roller 1.1' and the drawing roller 2.2' forming the nelson are drawn in red to form the drawn yarn Y2, and then the relaxing roller 3.3 is drawn.

The relaxed heat-treated yarn Y3 subjected to the relaxation heat treatment in step 3- is immediately applied with a processing agent containing an epoxy compound by a processing agent application device.When the processing agent containing an epoxy compound is applied, the relaxation heat treatment system Y3 It has heat heated by roller 3.3', and the treatment agent containing an epoxy compound has a heat of relaxation of 11! The heat generated by the yarn Y3 immediately brings it into a heat-treated state. When the yarn is wound onto the bobbin 5 using the winder 4, the yarn is traversed by a traverse guide provided in the winder 4. Requires free length.

きる。The relaxation heat treatment system Y3 to which the treatment agent containing the epoxy compound has been applied is largely stabilized while it travels the free length distance, for example, until it reaches the guide [+-rough]. When winding the material directly by reaching the winding machine without providing a guide roller rough, it is stabilized until it reaches the winding machine. If the above relaxation heat treatment system Y3
If the free length of the treatment agent containing an epoxy compound is short and the treatment agent containing the epoxy compound adheres to the guide roller 7 or the winding Ia4), the stretching roller 2.2' and the relaxation By controlling the humidity of the row '73.3' to be within the range of 150 to 235°C, the thirst marks of the C1 relaxation heat treatment system Y3 are indirectly controlled, and the epoxy is applied to the guide roller 7 and the winding machine. Adhesion of processing agents containing compounds can be eliminated or minimized.

If the temperature of the relaxation roller 3.3 is higher than 235°C.
'A decrease in the strength of the relaxation heat treatment system Y3 was observed, and the quality of the obtained yarn changed over time, and intermediate thread breakage was likely to occur. Therefore, it is more preferable that the temperature of the relaxing roller 3.3- and the final stretching roller 2.2- immediately before applying the treatment agent containing the epoxy compound is in the range of 150 to 235°C.
