These parameters show the excellent performance of Lycra composite TPU fabrics in terms of stretching, breaking, tear resistance, etc., making them ideal for sports uppers that require high strength and elasticity. For example, data on tensile strength and elongation at break show that the fabric can withstand greater deformation without losing its shape, which is crucial for the support of sneakers during intense exercise.
Table 2: Comparison of performance of lycaline composite TPU fabric and other common upper materials
| Material Type | Tension Strength (MPa) | Elongation of Break (%) | Tear resistance (kN/m) |
|---|---|---|---|
| Lycrab composite TPU | 20 – 40 | 500 – 700 | 50 – 80 |
| Ordinary polyester | 10 – 20 | 300 – 500 | 30 – 50 |
| Nylon | 15 – 30 | 400 – 600 | 40 – 60 |
As can be seen from Table 2, the Leica composite TPU fabric performed well in all test projects, especially in terms of tensile strength and elongation of break, which was significantly superior to other traditional materials. This superior performance is due to the additional structural support provided by the TPU layer, while Lycra fiber reinforces the elastic recovery capability of the material.
In addition, Leica composite TPU fabric also has good thermal stability and chemical resistance, which is particularly important for extending the service life of sports shoes. Overall, these parameters not only prove the wide application value of Leica composite TPU fabric in the field of sports shoes, but also provide a scientific basis for further optimizing its performance in the future.
Application technology of lyca fabric composite TPU fabric in sports shoes upper
Lyka BufuThe application of TPU fabric in sports shoes uppers involves a number of key technologies, including fabric structure design, composite process and molding technology. These technologies work together to ensure high performance of fabrics on sneakers.
Fabric Structure Design
Fabric structural design is the basis for the application of lyca fabric composite TPU fabrics. Depending on different sports needs, designers will adjust the arrangement and density of the fibers to optimize the elasticity and support performance of the fabric. For example, for running shoes that require higher elasticity, designers may adopt a denser arrangement of Lycra fibers; for basketball shoes, more attention may be paid to the thickness and distribution of the TPU layer to enhance support. This customized structural design helps improve the overall performance of sports shoes.
Composite Process
Composite process refers to the process of combining Lycra fibers with TPU films. This process usually uses hot pressing or adhesive. The hot pressing composite uses high temperature and high pressure conditions to closely combine the two materials. This method not only ensures a firm connection between the two, but also reduces the use of excess glue, thereby reducing the weight of the upper. Adhesive composite is suitable for occasions where special textures or patterns are required. By precisely controlling the amount and distribution of glue, more complex surface effects can be achieved.
Modeling Technology
Modeling technology involves the process of cutting and sewing composite fabrics into uppers. In the production of modern sports shoes, advanced technologies such as laser cutting and ultrasonic welding are often used to complete this step. Laser cutting can achieve extremely high accuracy, ensuring that each piece of fabric accurately matches the shape of the shoe last. Ultrasonic welding eliminates the need for traditional needles and threads, which not only improves production efficiency, but also reduces the thickness at the joints and increases the comfort of the upper.
Through the collaborative application of the above technologies, Leica composite TPU fabric can give full play to its advantages of high elasticity and support performance to meet the needs of different sports scenarios. These technologies not only enhance the functionality of sports shoes, but also provide more possibilities for their appearance design.
