    Abstract: PURPOSE:A specific amount of a hydrophobic silica made by the dry method, with alkyl groups on its surface and blocked silanol groups, having a specific particle size on the average in its primary particles is added to polyester, the mixture is subjected to high-speed spinning, then eluted on the surface to give the titled fiber inhibiting the fiber surface from roughening by cagulating particles. CONSTITUTION:Polyester containing 0.12-1.0wt% of hydrophobic silica particles made by the dry method, which have less than 100mmu average size in primary particles, have alkyl groups on the particle surfaces and blocked silanol groups on the surfaces, is extruded through the spinneret 11, passed through the cooling zone 12 to effect solidification and give yarn Y. A finishing oil is applied to the yarn by means of the applicator 13, the first goddet roller 14 and the second goddet roller 15 are used to regulate its yarn route and yarn speed and the yarn is wound up around the winder 16 at a speed of higher than 5,000m/min. Further, the resultant yarn is treated with a solubilizing or decomposing solvent to elute the surface, thus producting the objective yarn.

    Abstract: PURPOSE:Polyester fiber containing specific inert inorganic particles and polyalkylene glycol in specified amounts respectively is highly twisted and treated with an alkali to make the surface coarse, thus improving the color-developing property. CONSTITUTION:Polyester fibers containing (A) 0.1-4wt% of an inert inorganic particles with an average particle size of less than 5mu, preferably less than 100mmu, selected from the group consisting of silicon-containing inorganic fine particles such as mica or kaolin, oxides of metals of Group II in the periodic table or its salts such as zinc oxide or barium phosphate, thorium oxide and zirconium oxide and (B) 1-10wt% of a polyalkylene glycol of less than 5,000 molecular weight are strongly twisted or falsely twisted. Then, it is treated with an alkaline solution to reduce the weight by 10-30% to give the objective fiber.
