Manufacturing process and process optimization
The manufacturing process of high-performance spring-song composite TPU fabric involves multiple precision steps, each step directly affects the performance and quality of the final product. First, the preparation of base fabrics is a critical stage, and high-quality spring sub-spinning fibers are required to be selected and woven into fabrics with specific structures through advanced textile technology. During this process, the selection of fibers, the thickness of the yarn, and the structure of the fabric will affect the feel, strength and breathability of the fabric.
Next, the preparation of TPU films adopts melt extrusion or solution coating technology. The melt extrusion method is suitable for large-scale production, characterized by high efficiency and relatively low cost; while the solution coating method is more suitable for small-scale customized production because it can better control film thickness and uniformity. Regardless of the method, precise control of parameters such as temperature, pressure and time is required to ensure that the physical and chemical properties of the TPU membrane are in an optimal state.
Composite process is the core link of the entire manufacturing process. The TPU film and the spring spun substrate are usually tightly combined by hot pressing or adhesive. The hot press composite technology uses high temperature and high pressure to melt the TPU film and form a firm bond with the base cloth. The advantage of this method is that there is no need for additional adhesive, thereby improving the environmental protection of the fabric. Adhesive composite is suitable for certain special occasions, such as products that require enhanced edge sealing. In addition, in order to improve the composite effect, pretreatment of the substrate surface, such as corona treatment or plasma treatment, is often necessary to improve interface bonding.
After
, the finished product needs to go through a series of strict regulationsThe post-treatment process of grids includes functional treatments such as shaping, dyeing, and coating. These steps not only improve the appearance and feel of the fabric, but also further enhance its functionality. For example, a superhydrophobic layer can be formed on the surface of the fabric through special coating techniques, thereby significantly enhancing its waterproof properties. At the same time, in order to ensure the consistency of product quality, all finished products must undergo strict quality inspection, including physical performance testing, chemical stability testing and functional testing.
The famous foreign document “Advanced Materials for Functional Textiles” mentioned that “the manufacturing of modern textiles is not just a simple combination of materials, but also a fusion of art and science.” This fully demonstrates the high-performance spring-synthetics. The importance of every detail in the manufacturing process of composite TPU fabrics. By continuously optimizing various processes, not only can production efficiency be improved, but also cost can be effectively reduced, while ensuring that product quality meets high standards.

Comparison and development trend of domestic and foreign research status
Around the world, the research and development of high-performance spring-song composite TPU fabrics show obvious regional differences. European and American countries are in a leading position in this field with their strong scientific research strength and technical accumulation. For example, DuPont, the United States and BASF, Germany, have launched their respective high-performance TPU film products and have improved their waterproof and breathable performance through continuous technological innovations. In contrast, although the Asian region started late, it has also made significant progress in this field in recent years due to its labor cost advantages and rapidly developing manufacturing foundation. As one of the world’s largest textile producers, China’s companies such as Zhejiang Huafeng New Materials Co., Ltd. are gradually narrowing the gap with international giants.
However, there are certain differences in the key directions of domestic and foreign research. European and American scholars focus more on basic scientific research, trying to understand and optimize the structure and performance of TPU materials from the molecular level. The representative research results in this area come from a study from the University of Cambridge, UK, which revealed for the first time the dynamic behavior mechanism of TPU molecular segments under different environmental conditions, providing theoretical support for the design of smarter adaptive fabrics. At the same time, research in Asia is more inclined to the development of applied technology, especially in the field of how to reduce production costs and improve large-scale production capacity. For example, a study by Yonsei University in South Korea showed that adjusting polymerization reaction conditions can significantly improve the mechanical strength of the TPU membrane while reducing raw material consumption.
In terms of future development trends, intelligence and sustainable development will become the two core themes. On the one hand, with the rapid development of Internet of Things technology and artificial intelligence, the concept of smart textiles is increasingly valued. The future high-performance Chunyashi composite TPU fabric is expected to integrate functional components such as sensors, data transmission modules, etc. to achieve real-time monitoring of human physiological signals and automatic response to environmental conditions. On the other hand, environmental pressure has forced the entire industry to accelerate its transformation to green production. At present, many companies and research institutions have begun to try to use bio-based raw materials to replace traditional petroleum-based TPUs, and at the same time develop more energy-saving and efficient production processes. For example, the Finnish VTT Technology Research Center recently developed a new TPU material based on lignin, which produces only half the carbon emissions of traditional methods.
In addition, interdisciplinary cooperation will also become an important force in promoting progress in this field. Through Integrated MaterialsResearchers hope to create new fabrics with superior performance and richer functions to meet the growing market demand.
