A washing/drying method, comprising: dipping a material to be washed into an aqueous solution containing a surfactant having a water repellency so that at least one molecular layer of the water repellent surfactant is attached to the surface of the material to be washed; and then drying the material

A washing/drying method, comprising: dipping a material to be washed into an aqueous solution containing a surfactant having a water repellency so that at least one molecular layer of the water repellent surfactant is attached to the surface of the material to be washed; and then drying the material according to a known drying method such as vacuum drying, shaking off, blowing with gas and heating; or heating the material to be washed with steam at a temperature of less than 100°C. in an atmosphere reduced to a pressure such that the boiling point of water becomes less than 100°C.; and then drying the material according to a known drying method such as vacuum drying, shaking off, blowing with air, and heating.

A washing/drying apparatus for a material to be washed and dried, comprising: a water vessel which contains an aqueous solution, comprising a surfactant having a water repellency, of a sufficient volume for dipping and thereby washing the material therein and thereby attaching water repellent surfac

A washing/drying apparatus for a material to be washed and dried, comprising: a water vessel which contains an aqueous solution, comprising a surfactant having a water repellency, of a sufficient volume for dipping and thereby washing the material therein and thereby attaching water repellent surfactant on the surface of the material; at least one shower washing device in which the material, following washing in the water vessel, is received and which removes superfluous water repellent surfactant attached to the material; and a vacuum chamber in which the material is received after being shower washed in the shower washing device and which dries the material, the vacuum chamber being maintained at a pressure at which the boiling point of water is less than 100°C. and producing jets of steam at a temperature of less than 100°C. and to which the material, as received in the vacuum chamber, is subjected and thereby heated, the vacuum chamber further comprising a gas blowing device which blows water of the aqueous solution from the surface of the material.
