The weaving process has a long history and is one of the oldest crafts in human history,which has had a profound impact on other craft technologies.In the development process of modern textile art,the form of textiles has transformed from a flat form to a three-dimensional form,which has profound significance for modern architecture and other art forms.Based on the Semper technical art system,this paper analyzes the three-dimensional process of modern textile technology from the perspectives of process procedures and process materials,including composition logic,process changes and tools used.It also analyzes the impact of modern textile technology on modern architecture and modern craft art.With the continuous development of textile technology and technology,textile art is gradually developing towards sculpture and structure.This three-dimensional development provides theoretical and technical support for the integration of various art forms,and textiles will become a more free form of expression for fiber artists.
