Abstract: A stretchable coated fabric is treated for water repellency with a fluorinated water repellent that comprises a copolymer containing a perfluoroalkyl group with six or less carbon atoms (C6 fluorinated water repellent). The use of no C8 fluorinated water repellents that contain perfluorooctanoic acid, perfluorooctane sulfonate, and the like makes the fabric exerts no influence on the environment. And the fluorinated water repellent has a toluene repellency of 100 seconds or longer; a synthetic resin solution applied to at least one side of the stretchable fiber fabric has a thixotropic index at 23° C. in a range from 1.4 to 2.0; and the synthetic resin has a 100% modulus of 5 kgf/cm2 or greater. This prevents the synthetic resin from leaking to the back side and allows formation of a resin coating film that has good film forming properties.
