For example, in sportswear, it provides athletes with a comfortable wearing experience and reliable protection; in terms of outdoor supplies, the fabric is used to make tents, backpacks and other equipment to ensure that users can stay safe in extreme environments; In the field of medical protection, its efficient anti-ultraviolet properties make it an ideal choice for work clothes for medical staff.
To sum up, jacquard stretch fabric composite TPU fabric occupies an important position in the modern textile industry with its unique structural design and technical advantages. Next, we will conduct in-depth analysis of the specific implementation of its UV-resistant technology and its impact on practical applications.
Principles of UV resistance technology of Jacquard elastic cloth composite TPU fabric
The UV resistance of jacquard stretch fabric composite TPU fabric mainly depends on its unique material combination and processing technology. By introducing specific chemical additives and physical barriers, this fabric can effectively block the penetration of UV light, thus protecting the body from harmful radiation. The following is a detailed introduction to the UV resistance principle of this fabric based on the basic characteristics of ultraviolet rays.
UV raysBasic Features
Ultraviolet Radiation (UV) is the part of the electromagnetic spectrum with a wavelength between 100nm and 400nm. It can be divided into three main bands: UVA (320-400nm), UVB (290-320nm) and UVC (100 -290nm). Among them, UVA has a strong penetration ability and can penetrate deep into the skin dermis, leading to aging and pigmentation; UVB mainly acts on the epidermis, causing erythema and burns; while UVC is absorbed by the atmosphere and usually does not reach the ground. However, long-term exposure to UV radiation increases the risk of skin cancer, so it is crucial to develop efficient UV-resistant materials.
The core mechanism of anti-ultraviolet technology
The UV resistance of jacquard elastic cloth composite TPU fabric is mainly based on the following two mechanisms:
-
Physical Blocking
The TPU coating acts as a dense film covering the surface of the fabric, which can reflect and scatter UV light, reducing the possibility of it directly penetrating to the skin. This physical barrier acts like a mirror or frosted glass, which uses the principles of reflection and refraction of light to reduce the energy density of ultraviolet rays. Studies have shown that the thickness and uniformity of the TPU coating directly affect its UV resistance. For example, when the TPU coating thickness reaches more than 5 μm, its UV transmittance can be reduced to less than 1% (Chen et al., 2018). -
Chemical Absorption
Adding ultraviolet absorbers (such as benzophenones and benzotriazole compounds) to the TPU coating can further enhance the UV resistance of the fabric. These chemicals can absorb UV energy and convert it into harmless heat release, thus avoiding damage to the skin by ultraviolet rays. Common UV absorbers include:- Benzophenone: Suitable for wide-band ultraviolet absorption, especially for UVB.
- Benzotriazoles: It has the characteristics of high stability and low toxicity, and is suitable for long-term use.
- Silicon modified UV absorber: It has both absorption and dispersion functions, which can improve the durability of the TPU coating.
Key factors in technology implementation
In order to ensure that the UV resistance of jacquard elastic cloth composite TPU fabric reaches the best level, the following key factors need to be considered:
| Key Factors | Description | Influence on UV performance |
|---|---|---|
| Coating thickness | The thickness of the TPU coating determines its physical shielding ability | The greater the thickness, the lower the UV transmittance, but too thick may lead to a decrease in breathability |
| Absorbent concentration | The amount of ultraviolet absorber added affects chemical absorption efficiency | The concentration is too low and the ultraviolet rays may not be fully absorbed, and the concentration is too high may affect the flexibility of the coating |
| Fabric Structure | The porosity and fiber arrangement of jacquard fabrics will affect the transmission path of ultraviolet rays | Dense braided structure helps reduce UV penetration |
| Surface treatment process | The adhesion and flatness of the coating determine its durability and consistency | Poor surface treatment may cause coating peeling or uneven |
For example, a study conducted by Smith & Johnson (2019) showed that the fabric’s UV protection with a double-layer TPU coating process (the inner layer is pure TPU and the outer layer is a TPU mixture containing UV absorbers) can provide UV protection for fabrics The coefficient (UPF) reaches 50+, far exceeding the industry standard requirements.
Experimental verification and data analysis
To evaluate the actual UV resistance of jacquard stretch-based composite TPU fabrics, researchers usually use UV spectrophotometers to measure their UV transmittance (TUV). The following are the test results of a typical product:
| Wavelength Range (nm) | Transmission rate (%) | Remarks |
|---|---|---|
| 290-320 (UVB) | 0.5 | Complied with international standards |
| 320-400 (UVA) | 1.2 | Get high standards of protection |
| Average | 0.85 | UPF > 50+ |
Experimental data show that the fabric exhibits excellent UV resistance in the entire band range and is particularly suitable for outdoor activity scenarios.
To sum up, jacquard stretch cloth composite TPU fabricHighly efficient UV resistance is achieved through a combination of physical shielding and chemical absorption. The next section will focus on the performance of this fabric in practical applications and its satisfaction with user needs.

To better understand its characteristics and scope of application, the followingIt is a detailed analysis of the main technical parameters and experimental data of the fabric.
Main Technical Parameters
The technical parameters of jacquard stretch cloth composite TPU fabric cover multiple aspects, including but not limited to physical properties, chemical properties and functional indicators. The following are several key parameters and their definitions:
| parameter name | Unit | Description | Typical |
|---|---|---|---|
| Ultraviolet Index (UPF) | – | UV protection coefficient, measuring the ability of fabrics to block UV rays | ≥50+ |
| Tension Strength | N/cm² | The great ability of materials to withstand tension | 150-200 N/cm² |

| Abrasion resistance | Number of loops | The integrity of the material after friction | >5000 times |
Experimental data support
In order to verify the accuracy of the above parameters, several research institutions conducted detailed experimental tests. For example, a study by the American Association of Textile Chemists and Colorists (AATCC) compared the UV resistance of different brands of jacquard stretch fabrics. The results show that the UPF values of all samples exceeded the industry standard (UPF 50+) and maintained stable performance after 50 washing cycles (Kim et al., 2020).
In addition, Toray Industries has pulled the TPU coated jacquard stretch cloth it producesExtension strength tests found that its average tensile strength is 180 N/cm² and its elongation at break is 120%, which is much higher than that of ordinary elastic fabrics (Toray Technical Report, 2021). This shows that the TPU coating not only enhances the fabric’s UV resistance, but also significantly improves its mechanical properties.
Multiple relationship between parameters
It is worth noting that the parameters of jacquard elastic cloth composite TPU fabric do not exist independently, but are related to each other. For example, higher tensile strength is usually accompanied by lower breathability, because the tighter braided structure, while improving the durability of the fabric, also limits air circulation. Therefore, the importance of different parameters needs to be weighed during the design process to meet the needs of specific application scenarios.
| Parameter relationship | Influencing Factors | Solution |
|---|---|---|
| UV resistance vs. Breathability | TPU coating thickness | Optimize coating formula with porous structure |
| Tension strength vs. Comfort | Fiber arrangement method | Introducing double-layer weaving technology |
| Waterproof vs. Wear resistance | Surface treatment process | Combined with nanocoating and mechanical reinforcement |
From the above parameter analysis, it can be seen that jacquard elastic cloth composite TPU fabric needs to consider a variety of factors in the design and manufacturing process to ensure its stable performance in different environments.
