Abstract
An object is to provide a cloth containing an organic fiber, which is excellent in the oil repellency, dirt-removal property by washing and water-absorbing property, and a textile product produced using the cloth. A means for solution is attaching a specific fluorine-containing polymer to a cloth containing an organic fiber, with a quaternary ammonium salt if desired, and thus making the water-absorbing property in accordance with JIS L1018A method (the instillation method) 60 seconds or less and the oil repellency in accordance with AATCC118-1992 grade 4 or higher.
