In the result the above problems have been dissolved. [0002] Various methods for providing water repellency [0007] Namely a doctor blade according to the present and water absorbability to only one surface of a cloth invention and a coating method (resin finishing method) have been tried. For example, Pat.

Further, a cloth having water water repellent to the front and back surfaces of a 15 absorbability is treated by water repellent and then may water absorbing cloth having a weight of 100-450 be used. In the case, the pretreated cloth is effectively g/m2 with the method of the above (3). used to coat a resin composition for water proof on one surface of it.
