PROBLEM TO BE SOLVED: To provide a combined filament yarn using a polymer alloy fiber by which cloth breakage in a dyeing step and practical durability when used as a fiber product for clothing are extremely improved, and to provide a combined filament yarn using a nanofiber aggregate, and a woven fabric formed of the combined filament yarns. SOLUTION: The combined filament yarn is formed of the polymer alloy fiber containing a polyamide resin and a polylactic acid resin, and a chemical fiber multifilament having a single fiber fineness of 1 dtex or more. The combined filament yarn is formed of a nanofiber aggregate having a single fiber diameter obtained by number average of 1-200 nm, and the chemical fiber multifilament having a single fiber fineness of 1 dtex or more.
