適宜併用してもよい。In the case of the present invention, it is necessary that the antifouling performance and the water-repellent and oil-repellent properties, which are contradictory to each other, are uniformly imparted to the fabric, and for that reason, the treatment of far infrared rays is essential. This far infrared ray is an electromagnetic wave having a wavelength range of several μm to several tens of μm. When the far infrared ray is absorbed by an object, it is resonantly amplified by the vibrational energy of molecules and converted into heat energy. It is used as heating energy for drying water. This can prevent defective drying such as conventional hot air drying and occurrence of migration due to drying from the surface, and can perform uniform drying even in the width direction. In the present invention, a melamine resin conventionally used as a fluorine-based water / oil / oil repellent durability improver may be appropriately used in combination.
