PROBLEM TO BE SOLVED: To provide an ultrafine fiber composition having excellent abrasion resistance and color fastness to rubbing sufficiently durable for interior use required to have durability such as furniture and automobile sheet and having a soft texture. SOLUTION: The ultrafine fiber is produced by treating an ultrafine fiber with 1-100 pts. of an aromatic, aliphatic or alicyclic aqueous polyisocyanate compound, especially preferably an aqueous polyisocyanate bonded with an alkylene oxide chain and 100 pts. of an aqueous polyurethane composition and drying the treated ultrafine fiber at≤120°C.
