Structure and characteristics of Jacquard elastic cloth composite TPU fabric
Jagua stretch fabric composite TPU fabric consists of three main structures, each layer contributing unique functions to the overall performance. The base layer is an elastic fiber substrate, usually made of nylon or polyester filaments. These fibers have high tensile strength and good resilience to ensure that the fabric can maintain its shape and stability under complex stress conditions. The intermediate layer is a jacquard fabric, which forms patterned textures through complex knitting or weaving processes, which not only enhances the visual effect, but also improves the grip and comfort of the fabric. The outer layer is a TPU film, a thermoplastic elastomer material with excellent water resistance, breathability and chemical corrosion resistance.
Material Characteristics Analysis
| Features | Description |
|---|---|
| Elasticity | Elastic fiber substrate liftIt provides up to 40% of the bidirectional stretching capacity, with a recovery rate of more than 95%, suitable for dynamic sports needs. |
| Breathability | TPU film adopts a microporous structure design, allowing water vapor molecules to pass through but preventing liquid water from penetration, and the moisture permeability can reach 30,000 g/m²/24h. |
| Waterproof | The surface TPU coating effectively isolates external moisture, and the hydrostatic pressure test results reach 10,000 mm H₂O or above. |
| Abrasion resistance | The outer layer TPU has been hardened and has a wear resistance level in accordance with ASTM D3389 standards, reaching level 4. |

According to the study of Journal of Applied Polymer Science (2020), the molecular chain structure of TPU films has a significant impact on their performance. For example, TPUs with higher hard segment content exhibit stronger mechanical strength, while increased soft segment ratios will increase flexibility and elasticity. In addition, the texture design of jacquard fabrics will also affect the touch and functionality of the final product. Studies have shown that jacquard patterns of different densities and depths can change the friction coefficient and air circulation efficiency of the fabric, thereby optimizing the wear experience.
Application of Jacquard elastic cloth composite TPU fabric in the field of shoe materials
Jacquard stretch fabric composite TPU fabric has been widely used in the field of shoe materials due to its versatility and superior performance, especially in the design of sports shoes, casual shoes and outdoor shoes. The following will analyze its advantages and applicability in detail based on specific application scenarios.
Application in sports shoes
In the field of sports shoes, jacquard elastic cloth composite TPU fabric is mainly used in upper materials, and its high elasticity and breathability are particularly suitable for high-intensity sports scenarios. For example, Nike’s “Flyknit” series uses similar technology to achieve a lightweight and supportive balance of the upper through the combination of precision jacquard fabric and TPU film. Table 1 shows the performance comparison of this material in different types of sneakers:

Adidas uses similar composite materials in its “Ultraboost” range to create a unique visual effect through jacquard patterns, while the TPU layer guarantees the durability and waterproofing of the upper.
Applications in outdoor shoes
For outdoor shoes, the protective performance of the material is particularly important. The Jacquard stretch cloth composite TPU fabric is designed with a multi-layer structure to effectively resist the invasion of wet and cold under severe weather conditions. For example, Columbia’s hiking boots range uses this material to achieve a dual function of waterproof and breathable, allowing users to keep their feet dry in extreme environments.
To sum up, jacquard elastic cloth composite TPU fabric has shown strong adaptability in various shoe materials with its unique physical characteristics and design flexibility, meeting the needs of different consumer groups.
The lightweight technology principle of Jacquard elastic cloth composite TPU fabric
The core of lightweight technology is to reduce the overall weight of the shoe material by optimizing the material structure and process flow without sacrificing its functionality. Jacquard stretch fabric composite TPU fabric is lightweight through the following three main mechanisms: microstructure design, material selection and production process improvement.
Microstructure Design
Microstructure design is the basis of lightweight technology. By adjusting the porosity and fiber arrangement inside the material, weight can be reduced while ensuring strength. For example, the TPU film adopts a microporous structure design, which not only ensures breathability but also reduces material thickness. According to Polymer Engineering and Science (2019), when the pore size of the TPU film is controlled within the range of 0.1-0.5 microns, its moisture permeability can reach 30,000 g/m²/24h, while its weight increases by only about 10% .
| Structural Parameters | Numerical Range | Influencing Factors |
|---|---|---|
| Porosity | 30%-60% | Affects breathability and weight |
| Fiber Diameter | 5-15 microns | Determines softness and strength |
| Interlayer bonding strength | ≥5 N/cm² | Ensure the integrity of the composite |
Material selection
Material selection directly affects the weight and performance of the shoe material. Jacquard elastic cloth composite TPU fabric uses lightweight but high-strength elastic fibers as the base material, such as nylon 66 or polyester staple fibers. The specific gravity of these materials is usually less than 0.9 g/cm³ and has excellent tensile resistance. In addition, the hardness and density of TPU films can also be customized by adjusting the formulation to meet specific needs.
Production process improvement
Optimization of production processes is a key step in achieving lightweighting. Traditional hot press composite processes can easily lead to excessively thick materials or poor bonding, while new low-temperature plasma treatment technology can significantly improve the bonding force between the TPU and the fabric while reducing energy consumption and waste production. A study published in Materials & Design (2021) showed that after low-temperature plasma treatment, the adhesion strength of TPU films increased by about 30%, while the production cycle was shortened by 25%.
Through the synergy of the above three mechanisms, jacquard elastic cloth composite TPU fabric has successfully achieved the goal of lightweighting, providing important technical support for the sustainable development of the shoe material industry.
Experimental data analysis: Performance performance of Jacquard elastic cloth composite TPU fabric
In order to verify the actual effect of jacquard elastic cloth composite TPU fabric in lightweight technology, we have carried out a number of experimental studies covering mechanical properties, breathability, waterproofness and durability. The following are the specific experimental design and data analysis results.
Mechanical Performance Test
In terms of mechanical properties, we selected three different composite fabric samples (A, B, C), representing different combinations of TPU film thickness and jacquard fabric density. The tensile strength and elongation of break are measured by a tensile tester. The experimental results are shown in the following table:
| Sample number | TPU thickness (μm) | Jacquard density (root/cm) | Tenyl strength (N/cm²) | Elongation of Break (%) |
|---|---|---|---|---|
| A | 30 | 20 | 120 | 35 |
| B | 50 | 25 | 150 | 40 |
| C | 70 | 30 | 180 | 45 |
Experiments show that with the increase of TPU thickness and jacquard density, the tensile strength and elongation of break of composite fabrics have increased, but the weight has also increased. Therefore, performance and lightweight requirements need to be weighed in practical applications.
Breathability and waterproofness test
Breathability and waterproofness are key indicators of shoe materials. We evaluated the moisture permeability and hydrostatic pressure values of composite fabrics using the ASTM E96 standard test method. The results show that the moisture permeability of all samples exceeded 25,000 g/m²/24h, while the hydrostatic pressure value was generally higher than 10,000 mm H₂O, far exceeding the industry standard requirements.
| Sample number | Moisture permeability (g/m²/24h) | Hydrical pressure (mm H₂O) |
|---|---|---|
| A | 28,000 | 12,000 |
| B | 30,000 | 15,000 |
| C | 32,000 | 18,000 |
DurabilityTest
Durability test includes two aspects: wear resistance and UV aging resistance. According to ISO 12947 standard, Sample B still maintains more than 90% of its initial performance after 10,000 wear cycles, while the UV aging test shows that its color fastness level is above 4, meeting the needs of outdoor use.
