Abstract: In order to explore the new design method of blue calico pattern, the quadratic function of Julia set graph is changed by superposition polynomial function method to form a new Julia set graph. Select the specific elements of Julia set graphics, and use Photoshop to carry out the secondary design of the pattern to fully reconstruct the traditional pattern of blue calico. And then, adopt digital printing technology to print the pattern on the blue calico, so as to realize the application of the reconstructed pattern in the design of knitted garment.

Key words: Julia set graphics; blue calico ; secondary design; design method
