The investigation into digital Jacquard textile design in the colorful mode is one form of research in digital Jacquard fabric design, which aimed at expanding past and present jacquard design and production methods towards innovative ends. In this paper, the design principles and design methods for unconventional digital Jacquard fabric design in colorful mode have been analyzed based on the new technologies and computer applied color theory. The results of this study will enhance further research in the area of digital textile.展开更多

In this paper, the principles of digital jacquard fabric design were classified into two parts, colorless mode and colorful mode, and an innovative layered combination design method has been suggested contenting with this new design concept, by which digital jacquard fabric can be designed from colorless single-layer structure to colorful compound structure. As a result, designed colorless and colorful jacquard fabrics are capable of expressing picturesque and photo-realistic effects with a mega level color number on face of fabric. It is envisaged that the results of the study are of tremendous benefit to the creation of new jacquard fabric with an inimitable digital effect and this creation pose no problem in mass production.展开更多
