PROBLEM TO BE SOLVED: To provide a fire-extinction curtain which shows excellent fire-extinction properties against flames and can be used not only as a fire-extinction implement at early fire extinguishment but also as a fire-preventing implement for body protection in the flames.SOLUTION: The fire-extinction curtain is composed of a fabric made by mixed spinning, combined plying, combined weaving and/or combined knitting of modacrylic fiber with a heat resistant fiber or a nonflammable fiber. In addition, the fire-extinction curtain is composed of the fabric made of the modacrylic fiber whereon a coating of a silicone compound is formed. Besides, the fire-extinction curtain is composed of the fabric made of the modacrylic fiber to which metal compound particles causing water discharge due to pyrolysis accompanied by heat absorption are fixed by the medium of the coating of the silicone compound, the heat resistant fiber, and/or the nonflammable fiber.

PROBLEM TO BE SOLVED: To provide an NF membrane with high salt rejection.SOLUTION: The NF membrane is composed of a dehydrochlorination condensate of a chlorine-contained polymer and a multivalent amino group-contained compound. Zeta potential of the surface is positive in a range that a pH is 6 to 7. A Ca removal rate obtained by the following formula is equal to or larger than 70%. Ca removal rate=[1-(Ca amount in permeate)/{(Ca amount in feeding liquid+Ca amount in concentrate)/2}].

PROBLEM TO BE SOLVED: To provide an easy method for producing water-tightened, porous textile plane structure. SOLUTION: Hydrophobic particles having an average particle size of 0.02 to 100 μm, or non-hydrophobic particles that can be made hydrophobic in the following process steps are applied on the textile plane structure by using a suspension including the particles followed by removal of the solvent to fix the particles on the fibers of the textile plane structure and impart convex and/or concave patterns to the surface of the fibers. At this time, the convex parts characteristically have a intervals of 20 nm to 100 μm and a height of 20 nm to 100 μm whereby the water-tightness of the porous textile plane structure is increased.
