Beschreibung
Zusammenfassung:	PURPOSE:To provide the method giving the polyester fiber reduced in the breakage of the fiber and the generation of fuzzes, when the polyester fiber is produced by a high speed production method. CONSTITUTION:The method for producing the polyester fiber by spinning the polyester fiber at a rate of >=3000m/min and subsequently winding up the spun fiber is characterized by adhering a fiber-treating agent to the spun fiber, the fiber-treating agent containing 1-20wt.% of a polyalkylene oxide-modified polysiloxane of the formula (R1 is 3-4C alkylene; R2 is 1-8C alkyl, H; m is 0-5; n is 1-5; a, b are 1-10) having an average mol. wt. of
