Through the above parameter analysis, it can be seen that the jacquard elastic cloth composite TPU fabric has shown strong competitiveness in the field of automotive interiors with its excellent physical and chemical properties. The next section will focus on the specific implementation methods and principles of its anti-fouling and antibacterial technology.
Implementation mechanism and principle of anti-fouling and antibacterial technology
The anti-fouling and antibacterial technology of Jacquard elastic cloth composite TPU fabric mainly depends on its surface treatment process and the special properties of the material itself. Specifically, antifouling function is achieved through hydrophobic oleophobic coatings, while antibacterial properties are achieved through the addition of silver ions or other active antibacterial ingredients. The implementation mechanism and its working principle of these two technologies will be described in detail below.
1. Implementation mechanism of anti-fouling technology
The core of anti-fouling technology is to form a stable hydrophobic and oleophobic coating on the surface of the fabric, thereby effectively preventing liquids and grease from penetrating into the inside of the material. This processNano-scale fluorocarbons or silicone substances are often used for surface modification. When the droplets come into contact with the treated fabric, the droplets will be spherical and rolling rather than spread out due to the extremely low surface tension on the coating surface. This “loose leaf effect” makes it difficult for pollutants to adhere to the fabric and can be easily removed by simple wiping even with a small amount of residue.
| Technical Parameters | Description |
|---|---|
| Contact Angle | ≥110° (water drop contact angle), ≥60° (oil drop contact angle) |
| Durability | After at least 20 standard washing cycles, the anti-fouling performance will decrease by no more than 10% |
Study shows that the stability of this hydrophobic oleophobic coating is crucial to maintaining the long-term anti-fouling effect of the fabric. According to standard tests from the American Society of Materials Testing (ASTM), jacquard stretch fabric composite TPU fabrics can maintain high stain resistance after multiple cleanings.
2. The principle of action of antibacterial technology
Anti-bacterial technology is achieved by introducing silver ions or other active antibacterial ingredients into the TPU film. As a broad-spectrum antibacterial agent, silver ions can destroy the integrity of bacterial cell membranes, interfere with their metabolic processes and eventually lead to bacterial death. In addition, some new antibacterial agents can also inhibit the growth of fungi and mold, further improving the hygiene performance of the fabric.
| Anti-bacterial performance indicators | Description |
|---|---|
| Anti-bacterial rate | The antibacterial rate of common pathogens such as E. coli, Staphylococcus aureus has reached more than 99.9%. |
| Permanence | The antibacterial effect does not significantly weaken during normal service life |
A study published in the famous foreign document Journal of Applied Microbiology pointed out that the dispersion uniformity of silver ion antibacterial agents in composite materials directly affects its antibacterial efficiency. Therefore, it is necessary to strictly control the amount and distribution of silver ions in the production process to ensure good antibacterial effect.
To sum up, jacquard elastic cloth composite TPU fabric successfully achieves the dual functions of anti-fouling and anti-bacterial through advanced surface treatment technology and reasonable material selection. These technologies not only enhance the practical value of the product, but also bring users a healthier and more comfortable user experience.
Experimental data support and practical application case analysis

2. Practical application case analysis
1. Seat application of a luxury car brand
A well-known luxury car brand has fully adopted jacquard stretch cloth composite TPU fabric as seat covering material in its new models. After a year of actual use feedback, car owners generally reported that the seat surface is easy to clean and there will be no obvious stains or odor even if they drive for a long time. More importantly, due to the excellent antibacterial properties of the fabric, the air quality in the car has been significantly improved, further improving the driving experience.
2. Commercial Vehicle Interior Upgrade Project
In an upgrade project for commercial vehicle interiors, jacquard stretch fabric composite TPU fabric is widely used in multiple parts such as seats, door panels and floor mats. The project manager said that this fabric not only solves the problem of traditional interior materials being easy to dirty and difficult to clean, but also greatly reduces the maintenance costs caused by bacterial growth. It is estimated that cleaning costs alone save about 30%.
From the above experimental data and practical application cases, it can be seen that the jacquard elastic cloth composite TPU fabric has achieved remarkable results in the field of automotive interiors with its excellent anti-fouling and antibacterial properties. In the future, with the continuous advancement of technology, I believe that this fabric will play an important role in more scenarios.
