PROBLEM TO BE SOLVED: To provide a treating agent for spraying on fiber products capable of keeping shape-retaining effect to keep wear feeling without spoiling feeling of clothing even in a moist state under high temperatures. SOLUTION: This treating agent for spraying on fiber products contains a methacrylic acid-based polymer (I) in which a structural unit derived from methacrylic acid is >=60 mole % based on the total structural unit and having 10,000-1,000,000 weight average molecular weight and a sulfonic acid-based polymer (II) having 10,000-1,000,000 weight average molecular weight and structural unit having sulfonic acid group in >=60 mole % based on the total structural units in a specific ratio of (I) and (II).
