    摘要： To provide a polyester composite fiber having a heat-shielding property due to high reflectance in an infrared wavelength range (800 to 3000 nm) easy to be changed into thermal energy, and having color development property comparable to that of conventional polyester fibers. The composite fiber is a core-sheath type composite fiber including a core component and a sheath component of 10: 90 to 30: 70 (mass ratio). The core component includes a thermoplastic polymer including a sunlight shielding material having an average particle size of 0.5 µm or smaller in 8-70 wt%. The sheath component includes a polyester-type polymer including heat-shielding fine particles in 0.5-10 wt%, the heat-shielding fine particles capable of maintaining color development property and having an average particle size of 0.1 µm or smaller which is smaller than that of the sunlight shielding material.

    摘要： The present invention relates to a composite fiber for obtaining a fiber having a strength at 100% elongation of 0.04 cN/dtex or less,
    wherein the composite fiber is composed of component X comprising a polyvinyl-based thermoplastic elastomer, or a thermoplastic polyurethane elastomer having a glass transition temperature of 0°C or lower, and component Y which is an easily soluble thermoplastic polymer,
    wherein the composite ratio (mass ratio) X:Y of the component X and the component Y is within the range of from 90:10 to 50:50, and
    wherein the composite fiber has a core-sheath structure in which the component X constitutes the core component, and the component Y constitutes the sheath component, in a cross section of the fiber.

    摘要： Provided is a polyamide fiber having excellent color developability, as well as a method for producing such a polyamide fiber, and a fiber structure. The polyamide fiber comprises a polyamide resin composition comprising a polyamide resin and an amino group-containing color enhancer, the polyamide fiber having terminal amino groups at a concentration of from 5.0 µeq/g to 40.0 µeq/g. Such a fiber can be produced by a production method at least comprising: melt-kneading a polyamide resin composition including a polyamide resin and an amino group-containing color enhancer to give a melt-kneaded product having a predetermined melt viscosity; and spinning the melt-kneaded product to give fibers.
