Definition and background of lyka cloth composite TPU fabric
Lycra composite TPU fabric is an innovative material that combines the advantages of elastic fiber Lycra and thermoplastic polyurethane (TPU) and is widely used in backpacks and other outdoor equipment. This material is known for its superior elasticity and durability, providing modern outdoor enthusiasts with a more comfortable and reliable equipment choice.
Leika, or elastic fiber, is a synthetic fiber developed by DuPont, with excellent elasticity and recovery capabilities. It provides a good fit and comfort, allowing clothing or equipment to quickly return to its original state after stretching. TPU is a thermoplastic polyurethane elastomer rubber, known for its high strength, wear resistance and chemical resistance. By combining these two materials together, Leica composite TPU fabric not only inherits the advantages of both, but also has better physical properties and functionality.
In the field of backpack manufacturing, the application of lycra fabrics is gradually increasing. Its unique performance allows the backpack to maintain its shape while withstand heavy pressure, while providing better waterproof and breathable functions. The emergence of this material marks a major advance in backpack fabric technology and meets consumers’ growing demand for high-performance outdoor equipment.
Next, we will explore the specific performance of Leica composite TPU fabric in compressive resistance and durability, and illustrate its advantages through detailed technical parameters and practical application cases.
Compressive performance analysis
Lycra composite TPU fabric has excellent performance in compressive resistance due to its unique structural design. The fabric is made of lycra fiber and TPU layers, each layer playing a key role to enhance overall stress resistance. According to a study in the journal Advanced Materials Research, the compressive strength of composite materials mainly depends on the mechanical properties of each layer of materials and their interactions.
Material composition and structural characteristics
The Lycra fiber itself has a high elastic modulus, which means it can quickly return to its original state after being deformed under stress, thereby reducing the possibility of permanent deformation. The TPU layer provides additional support and protection, enhancing the overall toughness and tear resistance of the material. The combination of these two allows the Leica composite TPU fabric to effectively disperse pressure and maintain its shape when facing external pressure.
| Material Characteristics | Lycra fiber | TPU |
|---|---|---|
| Elastic Modulus | High | Medium |
| Tear Strength | Low | High |
| Abrasion resistance | Medium | High |
Compression test data
To verify the actual compressive resistance of lycaline composite TPU fabrics, we refer to a number of international standard testing methods, including ASTM D638 (tensile test) and ISO 13934-1 (break strength test). Here is a typical set of data:
| Test items | Unit | Data Value |
|---|---|---|
| Large compressive strength | MPa | 50 |
| Elongation | % | 200 |
| Fracture Strength | N/cm² | 800 |
These data show that the Leica composite TPU fabric can still maintain its structural integrity when subjected to pressures up to 50MPa and has an elongation of 200%, indicating that it has excellent elastic recovery capabilities.
Pressure resistance in practical applications
In practical applications, such as in the design of mountaineering backpacks, lyca fabric composite TPU fabric is used as the outer layer material. This is not only because it can effectively resist the pressure of the external environment, but also ensure the safety and stability of internal items. Furthermore, due to its high elasticity, the fabric can adapt to loads of different shapes and sizes, further improving the practicality and user satisfaction of the backpack.
To sum up, Leica composite TPU fabric has become an ideal choice for high-end backpack manufacturing with its excellent compressive resistance. This material not only performed well in laboratory testing, but also received widespread recognition and praise in actual use.
Durability Analysis
The durability of lyca fabric composite TPU fabric is one of its key properties as a high-performance backpack material. This material significantly improves its anti-wear and aging ability in long-term use by combining the elastic properties of Lycra fibers and the high strength and chemical resistance of the TPU.
Abrasion resistance
Anti-wear properties are particularly important for backpack fabrics, as backpacks often need to withstand friction and scratches. Lycra composite TPU fabrics effectively reduce material wear due to daily use by adopting high-density braiding technology and surface coating treatment. According to the research of “Textile Research Journal”, a specially treated TPU layer can make the fabric resistantThe grinding index has increased to more than three times that of ordinary textiles.
The following is the wear resistance comparison data of Leica composite TPU fabric and traditional nylon fabric:
| Material Type | Abrasion Resistance Index (Taber cycles) | Surface Damage Assessment |
|---|---|---|
| Lycrab composite TPU | 12,000 | Slight scratches |
| Traditional nylon | 4,000 | Sharp wear |
As can be seen from the table, the Leica composite TPU fabric is significantly better than the traditional nylon fabric in terms of wear resistance, and even after a long period of use, it only shows slight surface scratches.
Anti-aging properties
In addition to anti-wear properties, Leica composite TPU fabric also exhibits excellent anti-aging properties. The addition of TPU components not only enhances the mechanical strength of the material, but also increases its resistance to ultraviolet rays and chemicals. According to the research of “Polymer Degradation and Stability”, TPU can effectively resist degradation caused by ultraviolet radiation and extend the service life of the material.
| Material Type | UV Stability (%) | Chemical corrosion resistance (%) |
|---|---|---|
| Lycrab composite TPU | 95 | 98 |
| Traditional PVC coated cloth | 70 | 80 |
The data show that Leica composite TPU fabrics are superior to traditional PVC coated fabrics in terms of UV stability and chemical corrosion resistance, making them more suitable for long-term exposure to outdoor environments.
Summary
The durability of the Leica composite TPU fabric is due to its unique material combination and advanced processing technology. Whether it is anti-wear or anti-aging properties, this material can provide significant advantages, thus ensuring the long-term and reliable use of the backpack in various complex environments.
