    摘要： A resin composition includes an aliphatic polyester resin. The resin has carboxyl groups at the end termini of the molecular chain and at least one compound represented by the general formula (I), the compound being added to the resin to cap a part or all of the carboxyl groups at the end termini of the molecular chain of the resin. A process for producing a fiber includes mixing a pellet comprising an aliphatic polyester resin having carboxyl groups at the end termini of the molecular chain with a compound represented by the general formula (I) so that the content of the compound becomes 0.1 to 8% by weight and then melt-spinning the resulting mixture under the conditions of a spinning temperature of 200 to 250 C.°, a melt residence time of 180 to 1800 sec and a spinning rate of 500 to 10000 m/min. (I) wherein at least one of R1 to R3 represents a glycidyl group and the other group or groups independently represents or represent a hydrogen atom, an alkyl group having 1 to 10 carbon atoms, a hydroxyl group or an allyl group.
