Abstract: Provided are a method for producing a drawn conjugated fiber, capable of producing a conjugated fiber having a high strength and a thin fineness, and a drawn conjugated fiber. A drawn conjugated fiber is produced by performing a spinning step of obtaining an undrawn fiber having a core-sheath structure in which a core material is a resin containing, as a main component, a crystalline propylene polymer and a sheath material is a resin containing, as a main component, an olefin polymer having a melting point lower than that of the core material, by means of melt-spinning (step S1); and a drawing step of drawing the undrawn fiber (step S2).

During the production, a fineness of the undrawn fiber is adjusted to 1.5 dTex or less, and, in the spinning step, a melt flow rate of the core material discharged from the spinneret is adjusted to 70 to 170 g/10 minutes at 230° C. and a load of 21.

Abstract: A woven fabric made by using fiber-reinforced thermoplastic resin strands produced by stretching a bundle of sheath-core type conjugated filaments at a temperature of the melting point of the sheath component or above but below the melting point of the core component while fusing the sheath component, wherein the sheath-core type conjugated fiber is a nontwist straight one whose sheath component has a melting point lower than that of the core component by 20° C. or above; and articles made by using the fabric.
