For reaching the purpose of improving the dispersion performance of polyvinyl alcohol fibers in solution, a dispersant polyacrylamide was put to the solution. Furthermore, regression model was established. The box-behnken was adopted for designing the experiment. According to the analysis on the model, the optimal conditions for the dispersion of PVA fibers in solution were obtained. Finally, the dispersion mechanism of PMA on fibers was discussed. The results show that the response surface model can meet the reality and can better predict the fiber dispersion. The optimal conditions for the PMA dispersion fiber optimized by response surface method are as follows: PMA concentration is 0.2832%, fiber length, 12 mm, fiber content, 3.5 g. Under these conditions, the fiber can be best dispersed in the aqueous solution.
