Abstract
An elastic fiber of the present invention having an elastic fiber treatment agent attached to the fiber surface, comprises: a hydrocarbon resin (A) having a structure in which a polymer including a structural unit whose monomer is at least one selected from aromatic olefins and aliphatic diolefins as the main structural unit is partially or fully hydrogenated; and a hydrocarbon oil (B). In this way, an elastic fiber and a fiber structure comprising the same are provided that are suitable for obtaining an elastic sheet that has excellent elastic fiber unraveling properties and adhesiveness to hot melt adhesives, and that exhibits good adhesiveness even when processed at a high draft, and for obtaining a sanitary product that is soft to the touch.
