Abstract: Based on the problem caused by a large amount of consumptions for water, energy, and labor from fancy denim products, this study proposed a new fabric design approach and technology to circumvent this type of problem. The paper proposes the design concept to imitate semi-formed jeans with washing and grinding effects through digital jacquard design. A type of digitalized and fixed imitation image on typical denim jeans needs to be processed through computer-aided design. Variable shade structures respectively based on some typical denim weave are studied, and then innovative fabrics directly produced by the jacquard weaving can be shown and present certain denim washing and grinding effects. The paper gives design pattern which is especially for the integrated and semi-formed denim fabrics and clothing style, and presents a successful design experiment and methodology. The experiments ultimately have proven that this approach can not only achieve the eco-design and production of the denim without washing and grinding, but also improve the realization of the denim fabric and garment production efficiency and high value-added.
