Abstract: According to the design theory of digital image,the research of innovative digital jacquard fabric design can be divided into two parts: colorful and colorless.This paper makes an in-depth analysis of the innovative principle and design method of colorful digital jacquard fabric,sets forth theories on color design and construction design based on layer-by-layer combination and the method for building the database.The design method of colorful digital jacquard fabric is based on that of colorless digital jacquard fabric,and the structure design might compound several single-layer structures to form a multi-layer structure which makes the fabric capable of color presentation at a level up to millions.The innovative principle and method are beneficial to new product development and innovation of the colorful digital jacquard fabric and can satisfy the technical requirements of colorful digital jacquard fabric design by means of artificial intelligence.
