| abstract |
The elastic fiber of the present invention having an elastic fiber treating agent attached to the fiber surface has a structure in which a polymer comprising, as a main structural unit, a structural unit in which the monomer is at least one selected from aromatic olefin and aliphatic diolefin is partially or completely hydrogenated hydrocarbon resin (A); and hydrocarbon oil (B). In this way, it is suitable for obtaining an elastic sheet that has excellent elastic fiber unwinding properties and adhesion to hot melt adhesives, and exhibits excellent adhesion even when processed with high draft, and is also suitable for obtaining a hygiene product with a soft touch. An elastic fiber suitable for and a fibrous structure comprising the same are provided. |
