The specific test method comprises the following steps: filling tap water into the quincuncial cylinder, setting the rotating speed of a rotor to be 350r/min, after vortex in the cylinder is stable, setting the height from the water surface to the bottom of the vortex to be one third of the total height of the water surface in the cylinder, and placing a wet toilet towel substrate perpendicular to the horizontal plane at the center of the vortex in the cylinder; after 40s, the motor was turned off and the ventilation was stopped. And pouring the wet toilet tissue base material in the cylinder into a beaker, observing whether the wet toilet tissue base material is dispersed, judging that the dispersibility of the wet toilet tissue base material is qualified when one or more fragments appear, and otherwise, judging that the wet toilet tissue base material is unqualified.
