Furthermore, if the fabric hair direction after washing is in a chaotic state, the rolling brush of the cleaning appliance is more likely to form a spiral cyclone under high-speed rotation, increasing the dust accumulation effect and reducing the cleaning effect. The bevel anti-lodging three-dimensional fabric provided by the present application solves this problem and improves the cleaning effect. Moreover, the bevel of the bevel anti-lodging three-dimensional fabric provided by the present application can prevent winding, reduce the contact area of the rolling brush and the cleaning object, and thereby reduce the resistance of the cleaning appliance when starting, thereby improving the cleaning efficiency of the cleaning appliance.
