    Abstract: The present invention aims to provide a polypropylene fiber (PP fiber) excellent in strength, heat resistance, and water-absorption properties, a method of producing the same, and a hydraulic composition, a rope, a sheet-shaped fiber structure, and a composite material with an organic polymer each using the PP fiber. The present invention provides: a PP fiber having a fiber strength of 7 cN/dtex or more and having either or both of (i) DSC properties such that the endothermic peak shape by DSC is a single shape having a half width of 10°C or lower and the melt enthalpy change (ΔH) is 125 J/ g and (ii) irregular properties such that the single fiber fineness is 0.1 to 3 dtex and irregularities are formed on the surface, the irregularities having an average interval of 6.5 to 20 µm and an average height of 0.35 to 1 µm as a result of alternate presence of a protruded portion having a large diameter and a non-protruded portion having a small diameter along its fiber axis; a method of producing the PP fiber by pre-drawing an undrawn PP fiber having an IPF of 94% or more at 120 to 150°C at a drawing magnification of 3 to 10 times, and then post-drawing the resultant at 170 to 190°C and a drawing magnification of 1.2 to 3.0 times under the conditions of a deformation rate of 1.5 to 15 times/min and a draw tension of 1. 0 to 2.5 cN/dtex; and a hydraulic composition, a rope, a sheet-shaped fiber structure, and a composite material with an organic polymer each using the PP fiber.

    Abstract: Disclosed is a stainless steel filament made of a two-phase stainless steel having two-phase of austenite and ferrite, which is used as a PC tension material being a standing wire and as a wire rope being a running wire. The stainless steel filament contains 0.01-0.10 wt% of C, 0.1-1.0 wt% of Si, 0.30-1.50% of Mn, 0.010-0.040 wt% of P, 0.001-0.030 wt% of S, 18.0-30.0 wt% of Cr, 3.0-8.0 wt% of Ni, 0.1-3.0 wt% of Mo, and 0.10-0.45 wt% of N, the balance being essentially Fe and inevitable impurities, wherein the volume ratio of the ferrite amount to the sum of the austenite amount and the ferrite amount is specified to be in the range from 20.0 to 80.0%. Upon drawing, the drawing draft is in the range from 40 to 97%, the average aspect ratio (M R value) is in the range from 4 to 20, and the aging temperature is in the range from 150 to 750 °C.
