摘要

Provided are polyester fibers containing 0.2 to 20% by weight of a compound having a polyalkylenepolyamine skeleton to which groups having a polyalkylene oxide chain are bonded and having an HLB of 6.0 to 16.0, an average molecular weight of at least 10,000 and an amine value of not more than 500. These fibers have excellent water absorbent property with durability like that of natural fibers.
