First, the core layer of the fabric is a TPU film, a polymer material known for its excellent elasticity and toughness. According to standard tests from the American Society for Materials Testing (ASTM), the tensile strength of TPU films is usually between 20 and 40 MPa and can have an elongation of break of up to 300% to 600%. These characteristics ensure that the fabric is under various extreme conditions Still maintains the shape stability.

Secondly, the surface of the TPU film has been specially treated to enhance its adhesive properties with the cotton substrate. This process usually involves plasma treatment or chemical coating, aiming to increase the surface energy of the TPU film, thereby improving its adhesion. According to a study in the journal Soft Matter of the Royal Society, the peel strength between the TPU film and the cotton cloth that has been pretreated can reach more than 15 N/cm, which is much higher than the level of untreated samples.

In addition, the TPU film also imparts excellent waterproof performance to the composite fabric. By adjusting the thickness and microstructure of the TPU film, manufacturers can accurately control the water vapor transmittance (MVTR) of the fabric. For example, an experiment from the German Textile Research Institute showed that when the TPU film thickness is 50 microns, the MVTR of the fabric is about 5000 grams per square meter·day, which is enough to meet the needs of most outdoor activities. At the same time, the TPU film can effectively block ultraviolet radiation and extend the service life of the fabric.

To sum up, cottonCloth composite TPU film composite cotton fabric provides an ideal material solution for tent manufacturing by combining the high strength, good adhesion and excellent waterproofing properties of the TPU film.

Special application of cotton composite TPU film composite cotton fabric in tent manufacturing

Cotton composite TPU film composite cotton fabric is widely used in tent manufacturing due to its unique performance combination, especially in the design and production of high-end outdoor tents. The following discusses its specific applications and performance improvements brought by three main application scenarios – tent outer tent, inner tent and base cloth.

1. Tent external tent: dual guarantees of waterproof and windproof performance

The outer tent is a part that is directly exposed to the external environment and requires strong waterproofing and windproofing to protect the interior space from bad weather. The application of cotton composite TPU film composite cotton fabric in outer tents is particularly prominent. As an intermediate layer, the TPU film provides excellent waterproof performance. Its waterproof grade can usually reach more than 5000mm, far exceeding the waterproof standards of ordinary fabrics. In addition, the high elasticity of the TPU film allows the outer tent to maintain shape stability under strong wind conditions, reducing the risk of deformation or damage caused by wind pressure.

The following table lists the key parameters of cotton composite TPU film composite cotton fabric in external account applications:

Study shows that external tents using such fabrics can maintain high waterproof performance after long-term use. For example, the American outdoor equipment brand Big Agnes uses similar composite fabrics in its flagship product “Copper Spur HV UL2”. Field tests show that even under continuous rainfall for 72 hours, the tent outer tent still has no leakage. .

2. Tent Inside the Point: The balance between comfort and breathability

The main function of the tent inside the tent is to provide users with a comfortable living environment, so breathability is required.and mosquito-repellent properties. Cotton composite TPU film composite cotton fabric achieves good water vapor transmittance (MVTR) by optimizing the pore structure of the TPU film, while retaining the natural touch and flexibility of the cotton fabric. This feature allows the inner tent to effectively discharge moisture generated by the human body and avoid the sultry feeling.

The following are some important performance indicators in internal account applications:

According to a study by the University of Alberta, Canada, internal tents made of such fabrics perform well in high temperatures in summer, with internal humidity levels of about 15% lower than traditional polyester fabrics, significantly improving user comfort.

3. Tent base cloth: a combination of durability and moisture resistance

The tent base cloth is the part where the tent comes into contact with the ground. It must have extremely high wear resistance and moisture resistance to resist the piercing of sharp objects and the influence of water on the ground. Cotton composite TPU film composite cotton fabrics show unique advantages in such applications. The high-density structure of the TPU membrane effectively prevents moisture penetration, while its tough mechanical properties ensure that the base cloth can withstand long wear and pressure.

The following are key performance data in base cloth applications:

Australian outdoor brand Tentipi has introduced such composite fabrics in its ultra-light tent range, and has been proven on-site testing that its base cloth remains intact and remains intact under complex terrain conditions and exhibits stable moisture resistance in humid environments Effect.

In contrast, the cotton composite TPU film composite cotton fabric has greatly improved the waterproof performance through the addition of the TPU film, while retaining the comfortable touch of the cotton.

Secondly, although a single TPU film material has excellent waterproof and wear resistance, its tear resistance strength and flexibility are relatively weak due to the lack of a fiber support structure. Cotton composite TPU film composite cotton fabric is designed through a multi-layer structure, which not only enhances the overall strength, but also improves the flexibility and durability of the material. For example, according to research data from the European Textile Institute (ETI), the tear resistance strength of the composite cotton fabric is about 40% higher than that of a single TPU film, which means longer service life and more in actual use High reliability.

In addition, from an environmental perspective, cotton composite TPU film composite cotton fabric is also more sustainable. Since TPU films can be reused through recycling processes, while the cotton fabric is derived from natural plant fibers, this composite material is more environmentally friendly than synthetic materials that rely entirely on petroleum-based raw materials. A report from the U.S. Natural Resources Conservation Commission (NRDC) notes that using such composites can reduce the carbon footprint by about 30%, which is particularly important for modern enterprises pursuing green production.
