The electrostatic method could improve the carding action of the card. In this study, the static electricity was conducted to the working roller of the card would increase the holding of the card clothing for fibers on cylinder. Finally the carding effect of the working roller was investigated. The physical properties of fiberweb included the basis weight, thickness and strength of the fiberweb by changing the electrostatic voltage on the working roller. The experiment result showed that the polyester fiberweb uniformity was improved after the action of electrostatic carding. It was found that the carding effect is optimal when the electrostatlc voltages were 3 kV. However, it was found a phenomenon of electrostatic discharge when the voltages were over 3 kV, and thus causing a decrease for the fiberweb uniformity﹒
