PURPOSE: To produce a filamentary article for removing dust, having high dust removal capacity when applied to a brush or the like by the fluorination of a polyolefin-based resin surface of a filamentary article. CONSTITUTION: This filamentary article for removing dust, suitable for a removal tool having high dust removal capacity is produced at a low cost in a simple way by treating a filamentary object made of e.g. a polyolefin-based resin such as polyethylene in an airtight chamber filled with fluorine gas to fluorinating the surface of the object, cutting the fluorinated fiber at a right angle to fiber axis with a cutter or the like, and by bristling the fiber to form a brush, where the degree of fluorination is preferably 5-150μg/cm<2> . |
