Abstract: Technological innovation is an important way to help the high-quality development of the textile industry as well as an important measure to achieve the development of textile technology and industrial upgrading. Based on the incoPat patent database platform, this paper uses Gephi and other graph analysis software to analyze the development trend, dynamic evolution, hot spots and frontiers of domestic intelligent textile technology integration and innovation research. The results show that since the beginning ofthe 21^st century, the number of patented technology integration in this field can be roughly divided into germination stage, rapid growth stage and stable development stage, showing an upward trend year by year. After 2012, the patented technology integration with dimensions such as intelligence, security and efficiency tends to be pronounced. In terms of improving product convenience, reducing complexity and improving efficiency, the dynamic effect of technology integration is more significant. Through the visualization analysis of dynamic evolution data of technology integration, it is found that there are obvious differences in the number of fusion patents of intelligent textile technology in the three different stages. Under the influence of COVID-19, intelligent textile technology has played a positive role in promoting the safety and performance of medical protective clothing and related wearable devices.Finally, through cluster analysis and text mining, new models of intelligent manufacturing, intelligent textile equipment and commonalities technology, and new textile materials are the current research hotspots in this field, and technologies such as textile molding manufacturing, new textile fiber materials, advanced textile products and wearable systems have developed rapidly in the past two years, becoming the research frontier in this field.
