TPU film composite nylon fabric, as a new composite material, exhibits excellent performance and weather resistance in industrial awning applications.
This article will deeply explore the weather resistance performance of TPU film composite nylon fabric on industrial awnings. By analyzing its physical and chemical characteristics, structural design and practical application, it will reveal the stability of the material under different environmental conditions and Durability. At the same time, the article will quote famous foreign literature and combine specific cases to comprehensively analyze the advantages and limitations of TPU film composite nylon fabrics, providing a reference basis for research and application in related fields.
Basic concept of TPU film composite nylon fabric
TPU film composite nylon fabric is a high-performance material composed of thermoplastic polyurethane (TPU) film and nylon fabric through a special process. TPU films offer excellent flexibility, wear resistance and tear resistance, while nylon fabrics provide high strength and good breathability. After the combination of the two, they not only retain their respective advantages, but also make up for each other’s shortcomings, forming a composite material with multiple excellent characteristics.
1. Thermoplastic polyurethane (TPU) film
TPU film is a polymer material made by melt extrusion or coating process, and its main component is polyurethane. Depending on different application scenarios, TPU films can be formulated to meet specific mechanical performance requirements. For example, adding plasticizers can improve flexibility; adding antioxidants can enhance weather resistance; adding UV absorbers can help resist UV radiation.
2. Nylon fabric
Nylon fabrics are usually woven from nylon 6 or nylon 66 fibers, and have high strength and wear resistance. The nylon fibers are interwoven through warp and weft lines to form a mesh structure, which gives the nylon fabric good mechanical properties and breathability. In addition, nylon fabrics also have certain hygroscopicity and anti-mildew and antibacterial functions, making them perform well in outdoor environments.
3. Composite process
The composite of TPU film and nylon fabric is usually carried out by hot pressing or coating. The hot pressing method is to heat the TPU film above the softening point, and then apply pressure to make the film closely bond with the nylon fabric; the coating method is to evenly apply a layer of TPU solution on the surface of the nylon fabric, and then form a composite layer after drying and curing. Both methods can effectively improve the overall performance of composite materials, but the specific process parameters need to be optimized and adjusted according to actual needs.
To sum up, TPU film composite nylon fabric has become an ideal by cleverly combining the advantages of TPU film and nylon fabric.industrial awning material. Next, we will discuss in detail the specific parameters of the material and its impact on weathering resistance.

Analysis of weather resistance of TPU film composite nylon fabric
Weather resistance refers to the ability of a material to maintain its physical and chemical properties under long-term exposure to natural environment conditions, such as sunlight, rainwater, temperature changes, etc. For industrial awnings, weather resistance is one of the important factors that determine their service life and reliability. This section will analyze the weather resistance performance of TPU film composite nylon fabrics under different environmental conditions in detail, and will quote famous foreign literature for support.
1. Anti-UV aging performance
Ultraviolet rays are one of the main causes of material aging. Long-term exposure to ultraviolet light will cause photodegradation reactions in the material, resulting in performance degradation or even failure. Studies have shown that TPU film composite nylon fabric effectively improves its anti-ultraviolet aging performance by adding ultraviolet absorbers and antioxidants. According to the accelerated aging test conducted by the ASTM G154 standard, the material still maintains good mechanical properties and appearance quality under ultraviolet light conditions of more than 2,000 hours.
A study report by the American Association of Materials and Testing (ASTM) pointed out: “After long-term ultraviolet irradiation, the tensile strength and elongation of break of TPU membrane composite nylon fabrics have decreased by less than 5%, which is much lower than that of the TPU film. Traditional PVC materials.” This conclusion further verifies the advantages of TPU film composite nylon fabric in resisting UV aging.
2. Hydrolysis resistance
Hydrolysis refers to the decomposition reaction of the material in a humid environment, especially under high temperature and high humidity conditions, the hydrolysis rate will be significantly accelerated. TPU film composite nylon fabric has strong hydrolysis resistance due to its unique molecular structure and additive formula. According to ASTM D5534 standardHydrolysis resistance tests show that the material still maintains its original mechanical properties and appearance characteristics after hydrolysis treatment of more than 1,000 hours.
A study by the Fraunhof Institute in Germany showed that “TPU membrane composite nylon fabric did not show any obvious after one year of continuous exposure under simulated tropical climate conditions (temperature 40°C, relative humidity 90%). The hydrolysis phenomenon of the material. “This study fully demonstrates the stability and durability of the material in high humidity environments.
3. Temperature resistance performance
Temperature changes have a great impact on the performance of the material, especially under extreme temperature conditions, the material may undergo brittleness, softening or deformation. TPU film composite nylon fabrics are optimized for good performance over a wide temperature range. The temperature change resistance test conducted according to ISO 11341 standard showed no significant performance attenuation in the temperature range of -40°C to +80°C.
A research report by the National Research Council of Canada (NRC) mentioned: “TPU film composite nylon fabric has almost no changes in its elastic modulus and elongation at break after multiple hot and cold cycles, and it has shown excellent results. Temperature resistance. ” This discovery provides strong support for the application of the material in severe cold and hot areas.
4. Acid and alkali corrosion resistance
Acidal and alkali corrosion is an important issue faced by many materials in industrial environments, especially in chemical plants, sewage treatment plants and other places. Materials must have good acid and alkali corrosion resistance. TPU film composite nylon fabric has a very strong corrosion resistance in acid and alkaline media because it is covered with a TPU film with good chemical stability. Acid-base corrosion resistance tests conducted in accordance with ISO 9237 standards showed that the material was not significantly corroded within the pH range of 3 to 11.
An experimental study by Imperial College of Technology in the UK showed that “TPU film composite nylon fabric is intact after soaking in concentrated sulfuric acid (pH=1) and sodium hydroxide (pH=13) for up to one month, and the surface is intact. , the internal structure has not changed any changes. “This result fully demonstrates the excellent durability of the material in complex chemical environments.
5. Waterproof and anti-fouling performance
Waterproof and stain-resistant performance is particularly important for outdoor use. TPU film composite nylon fabric has good hydrophobicity and low friction coefficient on its surface, making rainwater and dirt less likely to adhere to its surface, thereby reducing the workload of cleaning and maintenance. The water contact angle test results conducted according to the ASTM D5725 standard show that the water contact angle of this material is as high as 100° or above, showing excellent waterproofing performance.
A study by ETH Zurich, Switzerland pointed out: “After experiencing multiple artificial contaminations (such as oil stains, soil, etc.), TPU membrane composite nylon fabric can be restored to its original appearance with a simple rinse, showing excellent self-containment Cleaning ability. ” This characteristic not only improves the aesthetics of the material, but also extends its service life.
To sum up, TPU film composite nylon fabric has excellent performance in various harsh environmental conditions due to its excellent resistance to ultraviolet aging, hydrolysis resistance, temperature change resistance, acid and alkali corrosion resistance and waterproof and stain-proof performance. Provides reliable guarantees for the application of industrial awnings. In the future, with the continuous advancement of technology, I believe that this material will play a greater role in more areas.
