Polyester binder fibers consisting of a water-dispersible copolymerized polyester, comprising at least one dicarboxylic acid and/or an esterforming derivative thereof, a glycol and an esterforming sulfonic acid alkali metal salt composition, wherein the total glycol component contained in the above mentioned polyester contains from 5 mole percent to 20 mole percent of a composition represented by the formula H-(OCH2CH2)n-OH, wherein n is an integer of from 2 to 13. The binder fibers are useful especially in a papermaking process. |
