PURPOSE: To produce an article having the surface of a fluorine-containing resin which places emphasis on water repellency by applying water incorporating fluorine-containing resin particles to the article and drying the dispersion liquid at the temperature not exceeding the fusion starting temperature through DSC measurement of the fluorine-containing resin and mutually fixing the fluorine-containing resin particles on the surface of the article. CONSTITUTION: Water, an organic liquid or a mixed dispersion liquid thereof incorporating fluorine-containing resin particles is applied to an article. The dispersion liquid is dried at the temperature not exceeding the fusion starting temperature through DSC measurement of the fluorine-containing resin under a state in which fluorine-containing resin particles are brought into contact with each other. Thereby, fluorine-containing resin particles are mutually fixed on the surface of the article in a nonfused state. Hereupon, the article having the surface of water-repellent fluorine-containing resin is constituted of an amorphous porous body which is formed of accumulation of mutual fluorine-containing resin particles having average particle diameter of at most 40μm and has the maximum IPA diffusion diameter of at least 8mm. Tangent value of an angle of water rolling is regulated to be at most 50/500. Thereby, the fluorine-containing resin layer having high water repellency is formed on the surface of the article by a simple installation and operation. |
