    • A part provided with an oil-repellent coating having an oil repellency great enough to enable droplets of fuel and lubricating oil to quickly slide off from the surface in the vicinity of an injection port of a fuel injector and a method of production of the same are provided. A part comprised of a metal base material on the surface of which an oil-repellent coating is provided, said part provided with an oil-repellent coating wherein said oil-repellent coating is constituted by a bottom layer of PES (polyether sulfone) adhered to a surface of the base material and a top layer formed by dispersion of discrete phases of FEP (tetrafluoroethylene-hexafluoropropylene copolymer) in a continuous phase of PES integrally formed with the PES of the bottom layer and wherein the top layer is exposed as the surface of the oil-repellent coating. A weight ratio PES wt %:FEP wt % of PES and PEP which form the oil-repellent coating is preferably 40:60 to 80:20, more preferably 60:40 to 75:25. Preferably, the surface of the base material is roughened so as to raise adhesion with the bottom layer of PES.
    • 具有防油涂层的部件具有足够大的斥油性,能够使燃料和润滑油的液滴从燃料喷射器的喷射口附近的表面迅速滑落及其制造方法, 提供。 由表面设置有防油涂层的金属基材构成的部分,所述部分设有防油涂层,其中所述防油涂层由附着在其上的PES(聚醚砜)的底层构成 基材的表面和顶层,其通过将FEP(四氟乙烯 - 六氟丙烯共聚物)的离散相分散在与底层的PES一体形成的PES的连续相中而形成,并且其中顶层作为 防油涂层。 形成防油涂层的PES重量%PESEPEP的重量比优选为40:60〜80:20,更优选为60:40〜75:25。 优选地,基材的表面被粗糙化,以提高与PES的底层的粘附性。

    • A moisture-permeable waterproof fabric which has a well-balanced combination of moisture permeability and waterproofing properties and has excellent strength, in particular, tensile strength, is provided without increasing environmental burden. A synthetic-polymer solution comprising a synthetic polymer consisting mainly of a polyurethane, fine inorganic particles, and a polar organic solvent is applied to one surface of a fibrous fabric and then brought into contact with a gaseous phase in which waterdrops having an average particle diameter of 1-30 μm have been evenly dispersed, thereby making the synthetic polymer semisolid. The fabric is then immersed in water to completely solidify the polymer and thereby obtain a moisture-permeable waterproof fabric comprising the fibrous fabric and, united to one surface thereof, a microporous film of a single-layer structure comprising the synthetic polymer consisting mainly of a polyurethane (the number of micropores having a pore diameter of 0.1-5 μm is (5-200)×104/mm2 in a vertical cross-section, and the film has a tensile strength of 3-80 MPa, a moisture permeability as measured by the calcium chloride method of 6,000 g/m2·24 hr or higher or a moisture permeability as measured by the potassium acetate method of 6,000 g/m2·24 hr or higher, and a water pressure resistance of 60 kPa or higher).
