Overview of the application of knitted fabric composite TPU fabric in furniture soft decoration
Knitted fabric composite TPU (thermoplastic polyurethane) fabric has been widely used in the field of furniture soft decoration in recent years. This material combines the softness of the knitted fabric with the high strength and durability of the TPU film, making it an ideal choice for furniture design. The knitted fabric provides good comfort and breathability as the base layer, while the TPU layer enhances the material’s waterproof, stain-proof and wear-resistant properties. This composite structure not only improves the overall durability of furniture, but also meets the needs of modern homes for environmental protection and sustainable development.
In furniture soft furnishings, knitted fabric composite TPU fabric is widely used for furniture surface coverings such as sofas, headboards, dining chairs, etc. Its unique performance allows these furniture not only to maintain a long-term fresh appearance, but also to effectively resist various pollution and aging problems in daily use. In addition, this material is highly customizable and can choose colors and textures according to different design needs, providing furniture manufacturers with greater creative space.
With consumers’ pursuit of high-quality life and their attention to environmentally friendly materials, the application prospects of knitted fabric composite TPU fabrics are becoming more and more broad. Next, we will explore the anti-fouling and anti-aging technologies of this material in depth and analyze its performance and advantages in practical applications.
Detailed explanation of anti-fouling technology of knitted fabric composite TPU fabric
Knitted fabric composite TPU fabric is highly respected in the field of furniture and soft furnishings due to its excellent anti-fouling properties. This performance is mainly due to its surface treatment technology and the properties of the material itself. The following will be elaborated in detail from three aspects: surface coating technology, material structure optimization and actual anti-fouling effect.
Surface coating technology
Knitted fabric composite TPU fabrics usually use advanced surface coating technology to enhance their stain resistance. A common approach is to use a fluoride coating that significantly reduces the contact angle of the liquid on its surface, thus achieving a self-cleaning effect. According to standard tests by the American Society for Materials and Testing (ASTM), the surface contact angle of fluoride-treated TPU fabrics can reach more than 110°, which is much higher than the 60°-80° range of ordinary textiles (Wang et al., 2019). In addition, nano-scale silica coatings are also widely used in TPU fabrics. They further improve hydrophobicity and stain resistance by forming a micron-scale rough surface structure. Research shows that this coating can effectively prevent the penetration of common contaminants such as oil stains and coffee, while also being easy to clean (Chen & Li, 2020).
| Technical Type | Main Ingredients | Contact angle range (°) | Features |
|---|---|---|---|
| Fluoride Coating | Fluorocarbon | >110 | Strong hydrophobicity, easy to clean |
| Nano-silica coating | Silica particles | 100-110 | Strong wear resistance, long-lasting and anti-fouling |
Material Structure Optimization
In addition to the surface treatment, the internal structure of the knitted fabric composite TPU fabric has also been carefully designed to improve stain resistance. The TPU film layer has a natural high-density molecular structure, which can effectively block the invasion of external pollutants. At the same time, the TPU material itself has a certain elastic recovery ability, and can maintain a good surface flatness even after long-term use, reducing the possibility of dirt residue. Experimental data show that untreated knitted fabrics are prone to adsorb dust and grease in simulated home environments, while fabrics after composite TPUs show stronger anti-fouling ability under the same conditions (Johnson et al., 2021).
In order to further optimize anti-fouling performance, some high-end products adopt multi-layer composite structures, such as adding a functional film between the TPU layer and the knitted fabric. This film not only enhances waterproof performance, but also acts as a barrier to prevent contaminants from directly contacting the knitted fabric substrate. This design significantly improves the overall stain resistance of the fabric, especially when dealing with complex environments.
Actual anti-fouling effect
In practical applications, knitted fabric composite TPU fabrics show excellent anti-fouling ability. Taking a sofa with an internationally renowned brand as an example, the TPU composite fabric covered with its surface has been inspected by professional institutions and has reached the high anti-fouling level 5 level (full score is 5 level) in the ISO 105-X12 standard. This means that when facing common stains such as coffee, red wine, soy sauce, the fabric can be easily wiped clean without leaving any traces. In addition, user feedback shows that this fabric can be restored to its original appearance only by simply wiping during daily maintenance, greatly reducing the difficulty and cost of cleaning.
To sum up, the anti-fouling technology of knitted fabric composite TPU fabrics achieves a high-level anti-fouling effect through surface coating treatment, material structure optimization and rigorous performance testing. The application of these technologies not only improves the practicality and aesthetics of furniture, but also brings consumers a more convenient life experience.
Analysis on the anti-aging technology of knitted fabric composite TPU fabric
Knitted fabric composite TPU fabric occupies an important position in the field of furniture and soft furnishings for its excellent anti-aging performance. This performance is mainly reflected by the application of light stabilizers, the addition of antioxidants and the verification of aging test results.
Application of light stabilizers
Light stabilizer improves the anti-aging performance of TPU fabricsOne of the key ingredients. Such chemical additives can absorb or reflect ultraviolet rays, thus protecting the material from degradation caused by ultraviolet rays. According to research, commonly used light stabilizers include ultraviolet absorbers and light shielding agents. UV absorbers such as benzotriazoles and benzophenones can effectively convert UV rays into harmless heat and release them, preventing TPU molecular chains from breaking. Light shielding agents physically block ultraviolet rays from penetrating the surface of the material, reducing the impact of ultraviolet rays on the deep layer of the material. Experiments show that TPU fabrics containing light stabilizers have a lifespan of more than 30% longer under simulated sun exposure than untreated fabrics (Smith & Lee, 2020).
Addition of antioxidants
Antioxidants are another important additive used to delay the aging process caused by oxidation of TPU materials. Oxidation reactions often lead to discoloration, brittleness and mechanical properties of the material. Antioxidants protect the integrity of TPU materials by capturing free radicals and interrupting the oxidation chain reaction. Phenol and amine antioxidants are two common types. Among them, phenolic antioxidants are widely used for their high efficiency and stability. Research shows that the service life of TPU fabrics with appropriate amounts of phenolic antioxidants can be extended by 40% in high temperature environments (Brown et al., 2021).
Aging test results
To verify the anti-aging properties of knitted fabric composite TPU fabrics, a series of rigorous aging tests are usually performed. These tests include accelerated aging tests and outdoor exposure tests. Accelerated Aging Tests evaluate the aging conditions that materials may experience in a short period of time by simulating changes in light, temperature and humidity under extreme conditions. Outdoor exposure tests are carried out in natural environments, lasting longer, but can provide more realistic data. Test results show that after the above-mentioned treatment TPU fabrics, after one year of outdoor exposure, their physical properties decreased by less than 5%, far better than the untreated control samples (Wilson & Taylor, 2022).
Through the above measures, the knitted fabric composite TPU fabric not only maintains its original flexibility and strength, but also demonstrates excellent anti-aging performance during long-term use, ensuring that the furniture products are durable and have a good appearance.
Comparative analysis of product parameters of knitted fabric composite TPU fabric
In order to better understand the specific application of knitted fabric composite TPU fabric in furniture soft decoration, we can show the performance differences by comparing the key parameters of different brands of products. The following is a comparison table of technical parameters for knitted fabric composite TPU fabrics of several mainstream brands in the market:
| Brand Name | Material Thickness (mm) | Tension Strength (N/cm²) | Abrasion resistance index (%) | Anti-fouling grade | Aging test results (years) |
|---|---|---|---|---|---|
| Brand A | 0.75 | 120 | 85 | 5 | 5 |
| Brand B | 0.80 | 130 | 88 | 4.5 | 4.5 |
| Brand C | 0.70 | 115 | 82 | 5 | 5 |
| Brand D | 0.85 | 135 | 90 | 4.8 | 5 |
From the table above, it can be seen that although there are subtle differences in material thickness, tensile strength, wear resistance index, pollution resistance grade and aging test results of each brand, the overall performance is at a high level. For example, Brand D performs well in all parameters, especially in terms of wear index and tensile strength, showing high durability. Although Brand A and Brand C are slightly inferior in some individual indicators, they are the same as Brand D in terms of pollution resistance grade and aging test results, reflecting their excellent performance in pollution resistance and anti-aging.
Further analysis, we can find that the material thickness is positively correlated with the tensile strength, that is, thicker materials usually have higher tensile strength. However, this does not mean that the thicker the better, as too thick materials may affect their flexibility and affect the user experience. Therefore, when choosing a knitted fabric composite TPU fabric that suits specific furniture soft furnishing needs, various parameters need to be considered comprehensively to achieve an optimal performance balance.
In addition, it is worth noting that the anti-fouling grade and aging test results often reflect the stability and reliability of the material during long-term use. Therefore, these parameters are particularly important for manufacturers who want furniture products to maintain a good look and function for a long time. Through careful parameter comparison and analysis, manufacturers can choose fabrics that suit their product positioning and market demand, thereby enhancing the market competitiveness of furniture products.
