According to the present invention there is provided a method for opening a fabric, in which warp and weft yarns can be uniformly opened using a simple method without having to alter the fabric weaving procedure. The method is a method for opening a fabric (4) produced by weaving a warp yarn (2) and a weft yarn (3), each of which having a bundled plurality of fiber filaments (1). A contact body (6) is provided to a surface of the fabric (4) with a protective film (5) interposed therebetween, and the contact body (6) is caused to move over the fabric (4) obliquely, and in a relative manner, with respect to the longitudinal direction of the warp yarn (2) or the weft yarn (3), whereby the warp yarn (2) or the weft yarn (3) is spread.
