    摘要： In this polyester multifilament, a core-component high-viscosity polyester and sheath-component low-viscosity polyester have been composited into a core-in-sheath, wherein the difference in intrinsic viscosity between the core component and the sheath component is 0.20 to 1.00, the total fineness is 4 to 30 dtex, the single-yarn fineness is 1.0 to 5.0 dtex; the breaking strength is 5.0 to 9.0 cN/dtex, the fracture elongation is 12 to 45%, the degree of interlacement is 2.0 to 15.0/m, and the number of filaments thereof is 3 to 15. This fine-denier polyester multifilament has high strength and excellent wear resistance and convergence, and makes it possible to obtain a high-density thin woven fabric suitable for use with athletic and outdoor clothing by combining excellent durability, weaving properties, and fabric grade.

    摘要： Provided are a high-strength fiber composite and an applied product thereof, whereby it is possible for the inherent tensile strength of high-strength fiber yarns to be obtained, even when used in applications in which bending stress occurs, such as wires, or when stored while wound around a drum or the like. This high-strength fiver composite has a core produced by imparting twist to a high-strength fiver bundle produced by bundling high-strength fiber yarns, and a stiffening the twisted high-strength fiber bundle with a stiffening agent. In this high-strength fiber composite, the high-strength fiber yarns are resistant to breakage even when flexed, have a superior shearing strength, and can maintain the inherent tensile strength of high-strength fibers, even when used in applications in which bending stress occurs, such as wires, or when stored while wound onto a drum or the like. The strand structure, which has a strand construction composed of two or more of the high-strength fiber composites twisted together, maintains the inherent strength of the high-strength fibers, and affords more consistent tensile strength, as compared with when an equal number of high-strength fiber composites lacking the strand construction are used.

    摘要： The present invention relates to a method for producing a bundle of filament in non-twisted states from a plurality of filaments comprising:
    release-winding the filaments from a creel part consisting of a plurality of creels (1), each of which has a bobbin (2) wound with each of the filaments and rotates by a rotational axis under a release-winding tension, then, folding the released filaments together by means of multiple driver rollers (3a), (3b) and (3c); and
    winding the folded filaments over a winder (5) to produce the bundle of filament,
    wherein each of the creels (1) is equipped with a release-winding tension controller (6) (abbrev. to "tension controller") for regulating a rotational speed of the creel to control the release-winding tension of the filament to be constant,
    wherein the tension controller (6) is an electrical tension controller, characterized in that the electrical tension controller is a powder brake.
