Abstract: Under the requirements of upgrading, reconstruction and high-quality development, China's textile industry is confronted with fierce competition and transformation pressure. Based on the data of 38,295 invention patent applications, this paper takes the key generic technologies of China's textile industry as the research object, analyzes their innovation capability, development trend and technology life cycle by using patent measurement, patent index analysis and Logistic model. The results show that the key generic technologies of China's textile industry are closely related to the technical classifications of D01F, D06M, D01D, D04H, D06P and C08G, involving major categories like mechanical engineering, chemistry, physics and electronic circuits. Among them, technological breakthroughs in new textile materials, such as carbon fiber and aramid fiber, have become an important engine for the high-quality development of the chemical fiber industry and the textile industry. However, the life cycle of key generic technologies in the textile industry has entered a mature stage, and it is expected that the patent growth will have a recession after 2028. After China proposed to transform from a "major textile country" to a "powerful textile country" , green, flexible, intelligent and refined production has become the main trend in the development of key common technologies in the textile industry, and it is also a crucial force to improve technological innovation in the textile industry and promote its transformation and upgrading.
Under the influence of the concept of sustainable development and the "Made in China 2025" policy, it is extremely important to optimize the technology innovation ecology and realize the systematic improvement of innovation capabilities of the key generic technologies in the textile industry. And the rapid growth of key common technologies such as mechanical methods of chemical fibers, dyeing or printing of textiles, polymer compounds, vapor-phase or steam treatment of textiles and knitting has become a key force to promote the rapid development of domestic textile industry. At the same time, a number of patents with prominent new technological features, such as the chemical characteristics of artificial filament fibers or carbon fiber equipment, as well as the biochemical treatment of fiber products, have played a positive role in promoting the green development of the textile industry.
This paper is helpful to sort out the meaning and concept of key common technologies in the textile industry, as well as to analyze the subject of patent application, the capability of technological innovation and each stage of the technology life cycle. Under the guidance of the innovation-driven development strategy proposed by the Chinese government, the development of science and technology in the textile industry has achieved remarkable results, the innovation ability has been steadily improved, and the key common technologies have received extensive attention from enterprises, academia and local governments. Although the existing research objects involve a number of emerging industries and technologies, there is no research on the integration of key common technologies in the textile industry, including new textile fiber materials, advanced textile products, green manufacturing, intelligent manufacturing and advanced equipment. Therefore, this study attempts to supplement the existing research in terms of research object and research content, so as to potentially fill the gap in current research.
