Zusammenfassung: | PROBLEM TO BE SOLVED: To obtain a fiber member excellent in moisture-retaining property, hygroscopic property and absorbing properties of heavy metal ion and odor gas by applying an endothermic aromatic polymer separated and extracted from coal and having absorbing properties of heavy metal ion and odor gas to a fiber. SOLUTION: This fiber member is obtained by separating an aromatic polymer substance having endothermic light wavelength-converting characteristics and characteristics, etc., for absorbing heavy metal ion and odor gas from coal by a method separation by powdering, separation by specific gravity, solvent extraction, treatment of an aqueous solution of caustic soda or caustic potassium at a temperature not higher than a pyrolytic temperature of coal, forming the material into fine particles having |
