Abstract
Electrostatic flocking technology has been widely used, but there are few theoretical studies on the flocking process. In this paper, the key factors affecting the motion of the flock are investigated by analyzing the dynamics of the flock in an electrostatic field. The obtained equation of motion is solved using MATLAB. The influence of flock specification on the rotation and translation process is analyzed. At a constant electric field intensity, the rotation time is linearly positively correlated with the flock’s linear density; the maximum translational velocity is linearly positively correlated with the flock length-to-diameter ratio; and the minimum plate distance is linearly positively correlated with the flock’s linear density. The flock’s maximum translational velocity is proportional to the electric field intensity, and the change in the electric field intensity does not affect the rotation time and the minimum plate distance. The paper also provides the minimum plate distance of eight kinds of nylon flock under the electric field intensity of 50 kV/10 cm. Based on the calculation results, it is suggested that the flocking test first calculates the minimum plate distance based on the flock’s linear density. Then the optimal electric field intensity should be determined according to the flocked fabric’s flocking effect and fastness.
