The present invention relates to a method for evaluating the removal rate of fine dust adsorbed on the fabric surface. The method for evaluating the fine dust removal rate of the present invention includes the steps of: (a) preparing a black cloth and a non-adsorbed original cloth, (b) photographing the surface of the original cloth with a camera to obtain a first surface image, (c) Preparing a dust cloth by attaching fine dust to the original cloth, (d) photographing the surface of the dust cloth with a camera to obtain a second surface image, (e) removing the dust cloth by managing clothes Preparing the fabric, (f) photographing the surface of the removal fabric with a camera to obtain a third surface image, and separating the brightness of pixels constituting the first, second, and third surface images into a plurality of steps. And obtaining the brightness values of all pixels, comparing the brightness values of the second surface image and the third surface image, or the first, second, and third surface images to derive the fine dust removal rate of the fabric surface. Characterized in that. |
