| titleOfInvention | Polyester chips and fibers |
| abstract | [PROBLEMS] To reduce the production amount of regenerated cyclic dimer at the time of melt molding, to stabilize the process at the time of melt spinning, to produce a stable fiber with a small amount of oligomer precipitation at the time of weaving and weaving, and to the quality at the dyeing process To provide a polyester chip having excellent management performance and a method for producing the same. A polyester polymer chip obtained by using a trimethylene terephthalate unit as a main repeating unit and a titanium compound as a polycondensation reaction catalyst, an alkali metal salt solution having an alkali metal concentration in the range of 1 ppm to 20% by weight, and By contacting, a polyester chip having a regenerated cyclic dimer formation rate at 260 ° C. under a nitrogen atmosphere of 0.015 wt% / min or less is obtained.
