Abstract
PURPOSE:To prevent the surface of a condensation preventive waterproof sheet from dew-condensing and to obtain hygroscopic and moisture releasability and waterproofness by composing it of a fibrous base cloth formed of hydrophobic fiber and having water insoluble and water absorptive substance, two waterproof coating film layers formed on both side faces of the cloth and having nonpermeability, one of which contains moisture permeable, waterproof polymer material and the other of which contains nonmoisture permeable, waterproof polymer material. CONSTITUTION:A fibrous base cloth preferably has hydrophobic property, and employs, for example, knitted fabric of natural fiber treated in advance for water repellency or nonwoven fabric. A moisture permeable, waterproof coating film layer formed on one side face of the cloth contains as a main ingredient a waterproof polymer material which exhibits moisture permeability of 500g/m<2> in 24 hours or more with 20mum of thickness under the condition B of a moisture permeation testing method of moistureproof packaging material of JIS-Z-0208-1976. A nonmoisture permeable polymer material-containing waterproof coating film layer is formed on the other side face of the cloth, and the nonmoisture permeable polymer material exhibits moisture permeability of less than 100g/m<2> in 24 hours in the same moisture permeation test as described above.
