The method discloses a method for producing a one-way mixed-weaving woven fabric, which comprises the steps of 1, preparing a first layer of 0-degree warp yarns; 2, preparing a second layer 0-degree wrap yarns to an Nth layer of 0-degree warp yarns, wherein the N is a natural number which is greater than or equal to 2; 3, preparing an auxiliary layer of warp yarns; 4, preparing binding threads; 5, laying and weaving the materials prepared in the step 1 to the step 4 in a mixed mode so as to acquire the one-way mixed-weaving woven fabric; and 6, cutting and winding. According to the invention, the 0-degree warp yarns are laid in a one-way mode by adopting two or more layers of different fibers, and then mixed weaving is carried out finally, so that laying of two or more types of different materials can be realized, uniform distribution and consistency in thickness of the fibers in each area of the mixed-weaving woven fabric are ensured, and the gram weight of different 0-degree warp yarn fiber layers can be arbitrarily adjusted within a range of 30-3000g/m2, thereby realizing the designability in performance and cost of a composite material.
