PROBLEM TO BE SOLVED: To produce no poisonous gas at smoking, to make a member lightweight and high in elasticity, and to obtain both waterproofing and flame resistance at the same time by using an organic phosphor and nitrogen-containing compound and a specific water-repellent compounds in combination. SOLUTION: A water-repellent compound and organic phosphor and nitrogen- containing compound is stuck to molded natural fiber. The water-repellent compound is a compound having a water-repellent functional group, which is a saturated hydrocarbon group, an aromatic hydrocarbon group, a perfluoroalkyl group, etc. The water-repellent compound further has a hydroxyl group, an amino group, or a carboxyl group. This water-repellent compound includes a solvent base or emulsion base compound; and the solvent base compound is 2,2,2,-trifluoroethanol, etc., and the emulsion base compound is perfluoro-n-octanoic acid, etc. The organic phosphor and nitrogen-containing hydrocarbon compound is, e.g. melamine phosphate or melamine cyanurate.
