A method for preparing polyester fibers whose water absorbency is comparable to that of natural fibers in which, at a suitable addition time from polyester polymerization to a stage prior to spinning; hydrophilic inorganic particles such as calcium oxide particles, magnesium oxide particles, and manganese oxide particles are added at an amount of 0.01-50 weight % based on the total weight of the fibers. This method enables polyester fibers to have superior water absorbency as well as excellent physical properties. As the inorganic particles are low-priced, this helps to keep down the total cost of producing the fibers.
