A soil resistant fiber structure, including a fiber and a soil resistant resin fixed to at least a part of a surface of the fiber, wherein the resin has, in at least a part inside the resin, one or more regions dyed with osmium oxide as observed with a transmission electron microscope, at least one of the regions is circular, the regions have a maximum diameter of 100 nm or more and 500 nm or less, and the soil resistant fiber structure has a mass concentration ratio of oxygen atoms to fluorine atoms (O/F) of 3 or more as obtained by measuring the surface of the fiber with an energy dispersive X-ray analyzer. The present invention provides a fiber structure having high anti-adhesion property against aqueous soils and oily soils as well as soil release property by washing.
