Abstract: A new round of scientific and technological innovation will help promote the high-quality development of the textile industry and is the key to enhancing the international competitiveness of Chinese textile enterprises. Based on the textile patent technology transfer data as the research object, this paper adopts patent econometric analysis and complex social network analysis methods to comprehensively analyze the evolution process, structural characteristics and development trend of domestic textile patent technology transfer network. The results show that: Since the 21st century, the overall trend of textile patent technology transfer in China has experienced three stages: embryonic period, steady development period and rapid growth period. Under the state's adherence to the strategy of independent innovation and sustainable development of science and technology, domestic technology transfer activities in this field have shown an upward trend year by year, becoming an important link to help scientific and technological resources be transformed into productivity and economic advantages. In terms of the structural characteristics of the overall transfer network, the technology transfer network in this field has changed from nodes, edges and network connections are relatively loose, to the network map showing the network state of dense radiation of nodes and edges, and the technology transfer institutions and frequency have also increased significantly; The main subjects of transfer have gradually become the backbone of technology transfer activities from domestic leading enterprises and multinational companies in the early stage, to textile enterprises such as garments, fiber materials and chemical fibers in coastal areas such as Guangdong, Jiangsu and Zhejiang. In terms of the structural characteristics of individual networks, by establishing a two-dimensional matrix of "breadth-depth", D06 and D01 patented technologies such as textile treatment, fiber, spinning or spinning are located in the "high breadth-high strength" quadrant, which have long been favored by the market. The technology transfer of A41, B65 and D04 patents has also developed rapidly and obtained a wide range of market application prospects. With the help of the activity evolution map of patented technology subcategories, it is found that the scale of textile patent technology transfer in China has expanded rapidly after 2011, and the trend of node increase has shown a relatively significant trend, indicating that the transformation and upgrading of China's textile industry is closely related to the innovation of enterprises in different technical fields. The washing treatment of textiles, the production of artificial filament, thread, fiber and equipment dedicated to the production of carbon fiber, as well as the liquid, gas or steam treatment of textile materials, and other technology transfer activities are more prominent, becoming an important part of the domestic textile technology transfer network. With the influence of the concept of sustainable development and the "low-carbon" policy, the rapid integration and development of technologies in different fields, and the growth rate of patent transfer technologies such as A61 medical textiles and H01 electronic components has increased significantly. Especially the global new crown epidemic at the end of 2019, the technological innovation and transfer represented by medical textiles have a positive role in promoting the needs of society to resist the epidemic and improve the competitiveness of enterprise products, and have become an important part of the technology transfer market attention in recent years．
