Nishijin textile is a generic term for pre-dyed figured textile produced in Kyoto. Nishijin textile has realized various designs and functions by incorporating materials such as foils cut from paper. We integrated functional materials and digital technology into this traditional Nishijin textile. Heteroweave is a work that integrates functions by weaving different materials in the weft. Heteroweave have unique characteristics that are diffcult by conventional Nishijin textiles, such as "color change", "superimposition of digital information", "retention of solid shape" to the environment. Heteroweave also follows the traditional Nishijin textile manufacturing process, and shows that it is possible to incorporate various media expressions without changing the original design. This design concept is a widely applicable method for functionalizing weaving textiles. In this paper, we summarize the concept, basic design, details of concrete prototypes, and the method of exhibition.
