PROBLEM TO BE SOLVED: To provide a fiber structure having excellent water repellency and melting proof properties with excellent durability by using a fluorine-based water repellent considering environmental problems. SOLUTION: The fiber structure is characterized as follows. The fluorine-based water repellent is fixed in a layer form through a triazine ring-containing compound film or a film composed of a fluorine-based water repellent and the triazine ring-containing compound to the fiber surface. The fluorine-based water repellent is PFOA (perfluorooctanoic acid) and/or PFOS (perfluorooctane sulfonic acid) with <5 ng/g content thereof measured by an LC-MS (high-performance liquid chromatograph-mass spectrometer).
