Overview of cotton composite TPU film composite cotton fabric
Cotton composite TPU film composite cotton fabric is an innovative textile material with its core lies in combining traditional cotton with thermoplastic polyurethane (TPU) films through advanced composite technology. This material not only retains the comfort and breathability of the cotton cloth, but also gives it excellent waterproofing and durability. TPU films have been widely used in modern textiles due to their excellent elasticity, wear resistance and tear resistance. By combining it with the cotton, the functionality of the fabric can be significantly improved while maintaining a good feel and appearance.
In the field of waterproof clothing, the application of cotton composite TPU film composite fabrics is gradually becoming the mainstream trend. Compared with traditional waterproof coatings or PVC materials, TPU films have higher environmental protection and lower toxicity, which can meet consumers’ needs for health and sustainable development. In addition, this composite fabric has good moisture permeability, which can block external moisture while allowing internal moisture to be discharged, thus providing a more comfortable wearing experience. These features make cotton composite TPU film composite fabrics ideal for high-end outdoor clothing, raincoats, and other functional apparel.
The following will introduce the specific parameters, production processes and their application cases in waterproof clothing in detail, and further explore its advantages through comparative analysis.

- Complied with EU REACH regulations and reduced the impact on the human body and the environment.
3. Production process
-
Base preparation
- High-quality pure cotton fabric is used for the outer and inner layers, and the pre-treatment processes such as pre-shrinkage and shaping are used to ensure dimensional stability.
-
TPU membrane preparation
- TPU particles are heated to a molten state using an extruder and evenly coated on the surface of the base cloth by a precision coating device.
-
Composite Process
- Put the TPU filmCompound with two layers of cotton cloth through hot press bonding technology to form a three-layer structure.
- Control the temperature (approximately 120°C-150°C) and pressure parameters to ensure a firm bond between the layers.
-
After organizing
- The finished fabric is subject to functional organization such as anti-fouling and anti-static to further improve its performance.
From the above parameters and technical characteristics, it can be seen that cotton composite TPU film composite fabrics perform excellently in terms of functionality, comfort and environmental protection, providing a brand new solution for waterproof clothing.
The current situation and development trends of domestic and foreign research
Domestic research progress
In recent years, domestic scholars have conducted increasingly in-depth research on cotton composite TPU film composite fabrics, especially in material modification, processing technology optimization and functional improvement. For example, a study from the School of Materials Science and Engineering of Tsinghua University showed that by introducing nanoscale silica particles into TPU membranes, their UV resistance and mechanical strength can be significantly improved (Li et al., 2022). In addition, the China Institute of Textile Sciences has developed a new two-component spunbond nonwoven fabric as the support layer of the TPU film, further enhancing the overall performance of the composite fabric (Zhang & Wang, 2021).
International Research Trends
In foreign countries, the research on TPU film composite fabrics mainly focuses on the direction of high performance and intelligence. The “Kevlar® enhanced TPU composite fabric” launched by DuPont in the United States has attracted widespread attention for its excellent tear resistance (DuPont, 2023). The Fraunhofer Institute in Germany is committed to developing smart textiles based on TPU films, which can realize temperature regulation and humidity monitoring functions through embedded sensors (Fraunhofer Institute, 2022). In addition, Toray Japan has developed an ultra-lightweight TPU composite fabric with a gram weight of only 150g/m², but it can still maintain high waterproof and moisture permeability (Toray Industries, 2021).
Development Trend
From the current research trend, the development of cotton composite TPU film composite fabrics will present the following directions in the future:
- Multifunctional Integration: By adding functional additives or using multi-layer composite technology, the fabric has various characteristics such as antibacterial, radiation-proof, and self-cleaning.
- Intelligent upgrade: Combining IoT technology and wearable devices, develop intelligent functions with real-time monitoring and feedback functionsEnable textiles.
- Green Manufacturing: Further optimize production processes, reduce energy consumption and pollution emissions, and promote the sustainable development of the textile industry.
To sum up, domestic and foreign research in the field of cotton composite TPU film composite fabrics has made important breakthroughs and has shown a diversified and intelligent development trend. These research results provide strong technical support for the waterproof clothing industry.
Application Case Analysis
