    Abstract: PURPOSE:To obtain stockings, containing a delustering agent in a specific proportion and a polyamide filament prepared by forming a thin film of a resin component with a lower refractive index than that of a polyamide on the surface thereof as one constituent element and having high transparency and delustering properties. CONSTITUTION:Stockings are obtained by covering, e.g. (A) core yarn of elastic yarn with (B) polyamide filament (e.g. nylon 6) having a thin film of a resin component (e.g. a polyacrylic acid ester-based resin), containing 0-0.1wt.% delustering agent (e.g. fine titanium dioxide particles) and having a lower refractive index than that of the polyamide on the surface thereof and using the resultant yarn as knitting yarn. The aforementioned stockings are improved in both shiners and transparency and excellent in beautiful appearance.

    Abstract: PURPOSE:To provide the subject conjugate fiber composed of respectively specified polyurethane component and polyamide component, useful as a material for a stocking, a tricot, etc., and excellent in stress recovery characteristics, heat resistance, etc. CONSTITUTION:(A) A polyurethane composition having (15:85)-(22:78) weight ratio of low-molecular diol to polyol is obtained by melt blending (i) an elastic polyurethane preferably composed of a polycarbonate-based polyurethane alone with (ii) a crystalline urethane compound synthesized from an isocyanate and a low-molecular diol and having 180-250 deg.C melting point in an amount of 3-20wt.% based on the component (i). The resultant polyurethane and (B) a polyamide (e.g. nylon 6) preferably having >=210 deg.C melting point are respectively melted and then subjected to conjugate spinning for forming an eccentric conjugate fiber, thus obtaining the objective fiber.

    Abstract: PURPOSE:To obtain the subject nontwisted sized yarn capable of preventing the defect of UJIMORE (partial swell of beam surface, etc.) and imparting a nylon fabric with good weaving performance and good quality free from stretching and loosening, by specifying the elongation of the yarn. CONSTITUTION:The objective nontwisted sized yarn free from the swelling on the beam surface or the loosening of warp liable to be developed in the weaving of a drawn yarn produced by the high-speed spinning at >=3000m/min can be produced by conditioning a spun and drawn yarn of nylon fiber in such a manner as to give an elongation L(%) satisfying the formulas 0

    Abstract: PURPOSE:To obtain the titled filament showing high luster characteristics and high stretchability, by making the sectional outer shape of conjugated filament concentrically placing two thermoplastic polymers having different shrinkage percentages into a triphyllous shape. CONSTITUTION:The sectional shape of filament is made into a triphyllous shape and the deformation degree is 1.2-1.8, preferably 1.35-1.55. The conjugated interface at the sectional central part of the fiber of polymers A and B is substantially in parallel with one side between two leaves of sectional outer shape of fiber, a trapezoidal part at the single side from the central conjugated interface consists of the low-shrinkable polymer B and the other triangular part is made mainly of the high-shrinkable polymer A.
