Can . In this case, it is preferable to use glycol used as a raw material for polyethylene terephthalate as a solvent.
- alkaline earth metal compound (b) used in combination with the metal-containing phosphorus compound (a) one that reacts with the metal-containing phosphorus compound (a) to form an insoluble salt in the polyethylene terephthalate is used.
- the alkaline earth metal compound (b) may be used as a single species or as a mixture of two or more species.
- the contents of the metal-containing phosphorus compound (a) and the alkaline earth metal compound (b) are appropriately adjusted. It is preferable to do.
- the content of the metal-containing phosphorus compound (a) in the polyethylene terephthalate resin is in the range of 0.5 to 3 mol% with respect to the molar amount of the acid component contained in the polyethylene terephthalate polymer.

Thread breakage in the process increases.
- the content of the alkaline earth metal compound (b) is less than 0.5 times the molar amount of the metal-containing phosphorus compound (a), the deep color effect of the resulting polyester fiber may be insufficient. In addition, the polycondensation rate during the production of the poly (ethylene terephthalate) polymer decreases, and it may be difficult to obtain a polyethylene terephthalate polymer with a high degree of polymerization.

In this order, it is added to the reaction yarn. However, if only the metal-containing phosphorus compound (a) is added to the reaction yarn in the first stage of the polyethylene terephthalate polymer production process, the completion of the first stage reaction may be hindered. In addition, when only the alkaline earth metal compound (b) is added to the reaction yarn before the completion of the first stage reaction, if the reaction is an esterification reaction, coarse particles are present in the reaction yarn.
- the reaction when the reaction is a transesterification reaction, the reaction may proceed abnormally rapidly and cause a bumping phenomenon. For this reason, it is preferable to regulate the addition amount of the alkaline earth metal compound (b) in the first stage to 20% by mass or less of the total addition amount. That is, with respect to the alkaline earth metal compound (b), it is preferable to add 80% by mass or more of the total addition amount to the reaction yarn after the first stage reaction is substantially completed. Further, the addition of the metal-containing phosphorus compound (a) and the alkaline earth metal compound (b) must be completed in the second stage of the polyethylene terephthalate polymer production process before the intrinsic viscosity of the polymer produced reaches 0.3. Is preferred.
