The invention belongs to the technical field of dyeing and finishing technology. In order to eliminate static electricity on the surface of the fabric in the carbon sanding process of the existing fabric, a tentering process of an anti-static auxiliary needs to be added. However, the anti-static auxiliary will make the fabric feel soft. In order to achieve the same sanding effect, the tension of the sanding and the time for sanding are needed to increase, which will increase the probability of contamination of the variegated wool. Therefore, it is necessary to add an air-softening and hair-removing process of an anti-pilling machine, which significantly increases processing cost. In view of the above problems, the invention provides a method for improving surface electrostatic properties of carbon sanded fabrics. Alcohol-ether surfactants are added during the soaping process of the fabric after dyeing, the tentering process of the anti-static auxiliary before the sanding and the air-softening and hair-removing process after the sanding are eliminated, and the time of sanding is reduced at the same time. The method reduces the electrostatic effect of the fabric without increasing washing, and reduces the processing cost.
