PROBLEM TO BE SOLVED: To produce a fibrous structure having deep color properties with durability by forming a polymeric film containing a fluorine-based compound and a silicone-based compound on the surface of the fibrous structure comprising a conjugate yarn having a core-sheath structure containing a specific sheath yarn. SOLUTION: This fibrous structure is obtained by applying a treating liquid containing a fluorine-based compound, e.g. a tetrafluoroethylene- hexafluoropropylene copolymer and a silicone-based compound, e.g. an amino- modified silicone and further an ionic surfactant such as a cationic surfactant and a polymer comprising a compound having methylol group or an acrylic ester polymer to a fibrous structure comprising a polyester-based conjugate yarn having a core-sheath structure in which a yarn length difference between a core yarn and a sheath yarn is 25-30% and the cross-sectional shape of the sheath yarn is a multilobed modified cross section and/or the fiber surface of the sheath yarn is roughened, then carrying out heat treatment and forming a polymeric film having <=1.5 refractive index. The value of L of the fibrous structure is 8.5-12.
