Overview of lyka cloth composite TPU fabric
Leika fabric composite TPU fabric is a high-performance material that combines elastic fibers (Leika) and thermoplastic polyurethane (TPU), which is widely used in diving suits and other clothing that require high strength elasticity and waterproofing. This fabric is known for its excellent stretch and resilience, allowing the wearer to get excellent comfort and flexibility when moving underwater. In addition, its excellent waterproofing ensures divers can stay dry in extreme environments.
Lycra fibers, also known as spandex or elastic fibers, give this composite a unique elastic properties. TPU has become an ideal coating material for its excellent wear resistance and waterproof performance. When the two are combined, not only enhance the overall performance of the fabric, but also significantly improves durability and service life. The development and application of lyca fabrics are a major advance in the field of textile technology, especially in the innovative application of functional clothing.
In the next section, we will explore the technical details of this material, production process, and its specific application in diving suits, while analyzing its market prospects and future development directions. By citing relevant literature and technical materials, we hope to provide readers with a comprehensive and in-depth understanding.
Analysis of the super soft fitting technology of lyka cloth composite TPU fabric
The reason why Leica composite TPU fabric can achieve a super soft fit in a diving suit depends mainly on its unique structural design and advanced manufacturing process. This part will analyze its key technologies and principles in detail and demonstrate its superiority through data comparison.
Structural Design and Technical Principles
The lyca fabric composite TPU fabric consists of two main components: the inner layer is a highly elastic lyca fabric, and the outer layer is a TPU film with waterproof properties. This double-layer structure design not only ensures the softness of the fabric, but also provides the necessary strength and support. The addition of Lycra fiber greatly improves the elasticity of the fabric, allowing it to fit the human body curves closely, reduces water flow resistance, and thus improves diving efficiency.
The application of TPU film further enhances the waterproof performance and durability of the fabric. The TPU material itself has good ductility and tear resistance, which makes it ideal for use in environments where frequent stretching and compression are required, such as during diving activities. By covering the TPU in the form of a film over the Lycra fiber, moisture penetration can be effectively prevented while maintaining the breathability and comfort of the fabric.
Data comparison and advantage analysis
To understand the advantages of Lycra composite TPU fabrics more intuitively, we can compare them with other common suit materials. The following table shows the key performance indicators of different materials:
| Material Type | Elasticity Index (%) | Waterproof grade (mmH2O) | Abrasion resistance score (1-10) |
|---|---|---|---|
| Ordinary nylon | 30 | 500 | 7 |
| Neoprene | 45 | 1000 | 6 |
| Lycrab composite TPU | 80 | 2000 | 9 |
As can be seen from the table, the Leica composite TPU fabric performs excellently in terms of elasticity, water resistance and wear resistance, especially its elasticity index of up to 80%, far exceeding other materials, ensuring excellent patching Compatibility and comfort.
In addition, Leica composite TPU fabric is also produced using advanced hot pressing technology. This process uses precise control of temperature and pressure to perfectly combine the TPU with Leica fibers to form a seamless whole. This technology not only improves production efficiency, but also enhances the stability of the product and reduces stratification or cracking caused by long-term use.
To sum up, Leica composite TPU fabric achieves a super soft fit through a unique double-layer structure design and advanced manufacturing process, while also having excellent waterproofing and durability, making it a modern Ideal for diving suits.
Detailed explanation of waterproof pressure technology of lyka cloth composite TPU fabric
The waterproof pressure technology of Leica composite TPU fabric is the core of its efficient waterproof performance. This technology enhances the waterproofing ability of the fabric through special coating processes and materials combinations, ensuring that it can remain dry even in high-pressure underwater environments.
Basic Principles of Waterproof Pressure Technology
The core of waterproof pressure technology lies in the application of TPU film. As a thermoplastic polyurethane, TPU has natural waterproof properties and its molecular structure is closely arranged to effectively prevent moisture penetration. By uniformly applying a layer of TPU film on the surface of Lycra fibers, it not only enhances the waterproof performance of the fabric, but also maintains its original elasticity. In addition, the TPU film also has a certain breathability, allowing moisture to be discharged, thereby avoiding internal moisture.
Technical implementation and performance testing
To verify the waterproof performance of Lycra composite TPU fabrics, a series of rigorous tests are usually performed. The following table lists common test methods and their results:
| Test items | Test Method | Test results |
|---|---|---|
| Static Hydraulic Pressure Test | Observe the seepage under fixed pressure | >2000 mmH2O |
| Dynamic Water Pressure Test | Simulate waterproofing performance under actual diving conditions | No obvious leakage |
| Durability Test | Evaluation of waterproof performance after multiple washes | Stable performance |
These test results show that Leica composite TPU fabric can maintain excellent waterproofing even under high water pressure environments, and its waterproof performance is still stable after multiple use and cleaning.
Advantages in practical applications
In practical applications, the waterproof pressure technology of Leica composite TPU fabric provides significant advantages for diving suits. First, it greatly improves the waterproof performance of the diving suit, protects divers from cold water, and extends diving time. Secondly, due to the breathability of the TPU film, divers can keep their bodies dry and improve comfort even during long diving. Later, the durability of this fabric also means it can withstand repeated use and cleaning, reducing maintenance costs.
To sum up, the waterproof pressure technology of Leica composite TPU fabric successfully achieves efficient waterproof performance by leica fabric by leica fabric using the unique properties of TPU film and precise coating process, providing indispensable functional support for the diving suit .
