The invention provides a design method of grayscale emulational jacquard. The technical scheme mainly comprises the following steps: (1) design of a coloration organization, (2) design of a coordinate organization, (3) design of digital images of computers, (4) substitution of the coloration organization so as to be combined with the coordinate organization to form a structure chart of a textile,and (5) the production method of the grayscale emulational jacquard. The method comprises: allocating a group of silk yarns along the warp direction in the structure chart of the textile, and two groups of silk yarns along the weft direction in the structure chart of the textile, wherein one group of the two groups of the silk yarns is used for color developing, and the other group is used for fixing waving points instead of color developing, and enabling that the silk yarns in the same warp direction or weft direction for color developing can not be mutually covered. By utilizing the grayscale emulational jacquard designed according to the structure chart of the textile, the problem of undesirable grayscale emulational effect caused by the slippage of the silk yarns is solved, and the designed textile can meet the technical requirements of mass production.
