The invention relates to a design method for producing black-and-white emulated jacquard fabric by utilizing colored patterns. The technical scheme of the design method comprises the following main steps of: (1) color separation and lamination of computer numeral patterns; (2) design of a full-color structure; (3) structure replacement and combination to form a fabric structure chart; and (4) production and application of the fabric structure chart. According to the invention, colored pattern is digitized, color separation and lamination are carried out by primitive color, the full-color structure is designed and combined as well as is used for designing various layers of structures, a group of white silk yarns is arranged in warp direction of a combined fabric structure, the number of the silk yarn in weft direction is equal to that of the primitive color, and the color of the silk yarn is grey color after the primitive color is removed. The black-and-white emulated fabric produced by the design method can represent exquisite grey change. The designed fabric can satisfy the technical requirement of large-scale production.
