The research shows that there are similarities in the traditional dyeing and weaving processes of these three ethnic groups. No matter the production techniques, pattern elements or color matching, they can be restructured and integrated in the process innovation. Therefore, through the fiber creation experiment, the researcher demonstrated that the application of contemporary art creation concept can not only improve the artistic taste of traditional craft, but also enrich the transmission channels of ethnic culture and enhance the self-confidence of culture. The integration of traditional crafts promotes the political cultural exchanges of different nationalities and promotes the development of ethnic culture.
