This utility model discloses an acetate fabric, including a base fabric area and triangular units. The base fabric area is between adjacent triangular units. Along the fabric width direction, two adjacent triangular units are arranged in an alternating cyclic pattern, with their hypotenuses facing each other. Two alternating triangular units form a group. Along the fabric length direction, two adjacent groups of triangular units are arranged in a horizontally symmetrical cyclic pattern. Each triangular unit includes multiple protrusions, arranged in a ratio of 1:2:3:4 or 4:3:2:1 along the fabric length direction. In this utility model, two adjacent triangular units are arranged horizontally symmetrically along both the fabric length and width directions, with their hypotenuses facing each other in the width direction. The triangular units are formed by protrusions, thus reducing the contact area on the fabric surface and hindering the free and continuous flow of charge on the flat fabric. This causes the charge to accumulate at the protrusions, resulting in a discrete charge distribution. Therefore, when the charge encounters a weak discharge opportunity, it is easier for the charge to dissipate locally.
