    Abstract: PURPOSE:To obtain a porous sheet, in which granular substance is exposed on the surface of a thermoplastic flexible sheet into which solid granular substance is mixed, and which is suitable for a throwaway diaper, etc., is excellent in strength and can not permeate a liquid and can permeate vapor, by grinding the surface of said sheet, etc. CONSTITUTION:Solid granular substance such as glass beads is exposed on the surface of a thermoplastic flexible sheet in polyethylene, etc. into which said granular substance is mixed by grinding or buffing-grinding the surface of the sheet, and a sheet as a target is obtained. Preferably, a diameter of said solid granular substance is 1mu or more and is the sum, which is acquired by adding 60mu to the thickness of the flexible sheet, or less. Desirably, the granular substance is one obtained by water repelling-treating the surface, also.

    Abstract: PURPOSE:To obtain the titled compound as an ampholytic surface active agent in high yields in a pure form containing no impurity such as inorganic salt, by treating an alkyl ester of quaternary ammonium carboxylic acid with an anion exchange resin. CONSTITUTION:An ester shown by the formula I (R is 10-20C alkyl; R1 and R2 are 1-3C alkyl; X is Cl, Br. or I; R3 are 1-4C alkyl; n is 1-5) is treated with an anion exchange resin (preferably quaternary ammonium salt type with strong basicity), to give the titled compound shown by the formula II. Usually, the solution of the compound shown by the formula I is added to a column in which the resin is packed, and the compound is eluted with a lower alcohol. The compound shown by the formula I is obtained by quaternizing a tertiary amine shown by the formula III with a compound shown by the formula IV. Since the prepared compound shown by the formula II contains no impurity, inorganic salts do not precipitate when an aqueous solution of high concentration is made, and it has merit to keep the solution transparent.

    Abstract: PROBLEM TO BE SOLVED: To obtain a fin for heat exchanger, which is excellent in the hydrophilic property of the surface thereof which lasts for a long period of time. SOLUTION: A fin for a heat exchanger is provided with a surface, having a fine irregularity structure whose all or a part of metallic surface is coated with a hydrophilic substance, and the height of the irregularity structure is lower than 300μm and the actual surface area per 1cm of the same structure in a plan view is winder than 2cm while the surface is provided with a surface- treated metal, having a contacting area of 0.3cm or less per 1cm of rigid body surface when a flat rigid body is contacted with the surface of the irregularity structure. According to this method, the fin is excellent in the hydrophilic property of the surface thereof and the flow down of condensed water can be promoted.

    Abstract: PROBLEM TO BE SOLVED: To drastically lower the friction resistance that a metallic surface receives from liquid by coating the metallic surface, which has a fine rugged structure on the surface and has a contact angle with water of a specific value, with a liquid repulsive material. SOLUTION: The surface of a metallic material having the contact angle with water of in plane view is specified to >=3 to . The contact area when a smooth rigid body on the surface of the rugged structure is specified to per 1cm rigid body surface. The metallic surface coated with the liquid repulsive material has the contact angle with liquid larger than 90 deg.. An air layer is formed between the metallic surface and the liquid on account of the high liquid repulsive property of the metallic surface. Then, the metallic surface directly receives the friction resistance by air. Since the viscosity of the air is much smaller than that of the liquid, the friction resistance that the metallic surface receives is lowered.

    Abstract: PURPOSE: To provide a substrate surface with a highly water-repelling property economically and simply by precipitating crystalline of a wax or an oil and fat which has higher melting point than the temperature of the environments where the substrate is used on the surface of the substrate. CONSTITUTION: A water-repelling property-imparting method to be applied for rain outfits, etc., involves heating a substrate to the temperature close to the melting point of a wax or an oil and fat and applying the wax or the oil and fat to the surface of the substrate. The method further involves cooling the substrate to room temperature to precipitate crystalline on the surface of the substrate and, if necessary, keeping the substrate at a prescribed temperature for a prescribed period to provide water repelling surface. In the case where triglyceride is for example used as the oil and fat, an excellent water-repelling surface can be obtained by keeping the substrate at about 40 deg.C for two weeks. Or, the or oil and fat is dissolved in an organic solvent and after the obtained solution is applied to the surface of a substrate, the substrate is kept at the temperature at which the organic solvent volatilizes to precipitate crystalline on the surface of the substrate and, if necessary, the substrate is kept at a prescribed temperature for a prescribed period to provide the surface having a water repelling property.

    Abstract: PURPOSE: To enable the continuons and more effective development of a modifying effect on a cuticle fiber by selectively impregnating a chemical into a target part in the cuticle fiber. CONSTITUTION: A chemical is impregnated into a cuticle fiber by impregnating the chemical at a specific fixing temperature and varying the temperature. The fixing temperatur is defined by the temperature to keep >=25% of the shape by fixing cuticle fiber to a definite shape for 1hr and immersing the fiber in a water/ethanol mixture at -15 deg.C to release the fixation of the fiber, the temperature to keep >=15% and
