    摘要: The present invention provides: an acrylic fiber having a fineness of 0.5 to 3.5 dtex and having excellent gloss, pilling resistance, and texture; a method for producing said acrylic fiber; and a spun yarn and a knitted fabric containing said acrylic fiber. Provided is an acrylic fiber having a filament fineness of 0.5 to 3.5 dtex, wherein the product K of the value of knot strength (cN/dtex) and the value of knot elongation (%) is from 8 to 30 inclusive, and the number of recesses having a depth of 0.1 µm or greater is 10 or fewer. In this method for producing said acrylic fiber, an acrylonitrile-based copolymer containing 92 to 96.8 mass% of an acrylonitrile unit, 2 to 6 mass% of a vinyl-based monomer unit, and 0.2 to 2.0 mass% of a sulfonic acid group-containing vinyl monomer unit is dissolved in an organic solvent, to prepare a spinning dope. A coagulated fiber bundle is formed by discharging the spinning dope from discharge holes into a coagulation bath having a solvent concentration of 40 to 60 mass% and a temperature of 35 to 50 °C. The coagulated fiber bundle is drawn in hot water at a draw ratio of 2 to 3.8 times, an oil agent is applied, the fiber bundle is dried, and then the fiber bundle is drawn under dry heat at a draw ratio of 1.2 to 3 times.
    The product S of said draw ratio in hot water and said draw ratio under dry heat is from 4 to 6 times. Further, the fiber bundle is subjected to a thermal relaxation treatment.

    摘要: A spinning nozzle (1) which has a perforated part (2) in which ejection holes (3) have been arranged in a density as high as 600-1,200 holes/mm 2 . This process for producing a fibrous bundle comprises ejecting a spinning dope having a viscosity as measured at 50°C of 30-200 P from the ejection holes (3) of the spinning nozzle (1) to produce a fibrous bundle. This fibrous bundle has a single-fiber fineness of 0.005-0.01 dtex. By the wet-process direct spinning, a mass of nanofibers which are stably uniform and continuous can be produced at a high efficiency.
