Abstract: Printing process of thermochromic microcapsule was studied. Through single factor tests and orthogonal experiments, the effects of the concentration of binder and crosslinking agent and the baking condition were discussed. By testing color fastness and comforts of printed fabrics, the optimum printing process was obtained, which was the concentration of binder 25%, the concentration of crosslinking agent 1.5%, baking at 150 ℃ for 4 min. Furthermore, the color change of thermochromic materials is generally from one color to colorless and can not satisfied with the demand of market. In order to enrich the color of the printed fabrics, thermochromic microcapsule and pigment were blended with different proportion to match multifarious colors, which might provide the foundation for the more extensive design and application of thermochromic fabrics.
