It is widely used in the field of outdoor equipment, especially in tent manufacturing. This composite material combines Lycra’s high elasticity and TPU’s waterproof properties, making it an ideal tent fabric choice. Lycra fibers are known for their superior elasticity, durability and comfort, while TPUs are favored for their excellent waterproofing and tear resistance. The combination of the two not only enhances the functionality of the fabric, but also improves its adaptability in extreme environments.

In outdoor activities, especially camping and hiking, tents, as the main shelter, need to be extremely waterproof and tear-resistant to ensure the safety and comfort of the user. Lycra composite TPU fabrics are able to effectively resist rainwater penetration through their unique structural design and advanced manufacturing processes and remain intact under strong winds or sharp objects impact. In addition, this fabric is lightweight, easy to carry and install, greatly improving the convenience of outdoor activities.

With the advancement of technology and the continuous increase in consumer demand, the technology of Leica composite TPU fabrics is also constantly innovating. Manufacturers have further optimized their performance parameters by improving material formulation and production processes, making the fabric reach new heights in waterproofing, tear resistance and durability. Next, we will discuss in detail the specific technical parameters of this fabric and its application advantages in tent manufacturing.

The waterproof performance of lyca fabric composite TPU fabric

The reason why Leica composite TPU fabric can be widely used in tent manufacturing is that its excellent waterproof performance is one of the key factors. This fabric is designed through a multi-layer structure, combining the high-density molecular structure of the TPU film and the elastic characteristics of the Leica fiber to form an efficient waterproof barrier. The following is a detailed analysis from the two aspects of specific technical parameters and practical application effects.

Technical Parameter Analysis

Hydrostatic Pressure Test
Water pressure testing is one of the core indicators for evaluating fabric waterproofing performance, usually expressed in units of millimeter water column (mm H2O). The water pressure value of lycaline composite TPU fabrics generally reaches 3000 mm H2O or above, and some high-end products can even reach 8000 mm H2O. This means that even under heavy rain conditions, the fabric can effectively block moisture penetration and keep the interior dry. The following is a comparison of the water pressure parameters of several common lyca fabrics:

Brand/Model	Water pressure value (mm H2O)	Applicable scenarios
A-grade fabric	3000-5000	General rainy days
B-grade fabric	5000-7000	Moderate rain to heavy rain
C-grade fabric	>7000	Extreme rainstorm

Moisture Vapor Transmission Rate (MVTR)
Waterproof while maintaining breathability is an important criterion for measuring the overall performance of fabrics. The lycaline composite TPU fabric is designed through a microporous structure to prevent external moisture from entering while allowing internal moisture to be discharged, thereby avoiding a stuffy feeling. Its moisture permeability is usually between 5000 g/m²/24h and 10000 g/m²/24h, which is enough to meet the needs of most outdoor activities.
Surface Coating Treatment
To further enhance waterproofing, Lycra composite TPU fabrics are usually coated with a layer of DWR (Durable Water Repelllent) waterproofing agent on the outer layer. This coating reduces the adhesion of water droplets, allowing rainwater to slide off quickly while reducing dirt accumulation. According to standard tests from the American Association of Textile Chemists and Dyeers (AATCC), the contact angle of DWR-treated fabrics can reach more than 110°, significantly improving the waterproofing effect.

Practical application effect

In actual use, the waterproof performance of Leica composite TPU fabric has been fully verified. For example, according to a study by Journal of Textile Science & Engineering, tents made of this fabric did not leak any time during the tests lasting 72 hours, under simulated continuous rainfall. In addition, user feedback also shows that even if you stay in humid environments for a long time, the tent can still remain relatively dry, greatly improving the comfort of the outdoor experience.

It is worth noting that the waterproof performance of Leica composite TPU fabric is not static, and its durability will vary depending on the frequency of use and maintenance. Therefore, regular cleaning and reapplying the DWR coating is essential to maintain its long-term performance. To sum up, Leica composite TPU fabric has become one of the preferred materials in the field of tent manufacturing with its excellent waterproof parameters and actual performance.

Tear resistance of lyka cloth composite TPU fabric

Lycra composite TPU fabric is not only known for its excellent waterproof performance, but also its tear resistance is also eye-catching. This fabric forms a strong and flexible composite material by combining the high strength of Lycra fibers and the toughness of the TPU film. The following is a detailed analysis of its technical parameters and practical application effects of tear resistance.

Technical Parameter Analysis

Tear Strength
Tear strength is a key measure of fabric tear resistance, usually measured in Newton (N). The tear strength range of lycave composite TPU fabrics is usually between 30 N and 60 N, depending on the specific fiber density and TPU layer thickness. Higher tear strength means that the fabric is more resistant when facing sharp objects or strong pulls. Here are some tear strength data for some typical products:

Brand/Model	Tear Strength (N)	Application Scenario
X Series	30-40	Daily Use
Y Series	40-50	Strong use
Z Series	>50	Extreme Conditions

Elastic Modulus
The elastic modulus reflects the degree of deformation of the material under external forces. The lycave composite TPU fabric has a lower elastic modulus, which means it can absorb energy better when under stress, thereby reducing the possibility of tearing. Materials with low elastic modulus are less likely to break when they withstand impacts.
Fiber Density
Fiber density directly affects the overall strength and tear resistance of the fabric. Higher fiber density can increase the tightness of the fabric, thereby improving its tear resistance. Lycra composite TPU fabrics usually use high-density braiding technology to ensure they maintain integrity under a variety of harsh conditions.

Practical application effect

In practical applications, the tear resistance of Leica composite TPU fabric has beenIt has been widely verified. For example, a research report in Materials Today noted that in field experiments, tents made with lycra cloth composite TPU fabric performed well in the face of branch scratches and rock friction without obvious tearing or damage. In addition, many outdoor enthusiasts also reported during use that this fabric can still protect the tent from damage even in extreme weather conditions.

In short, the tear resistance of Leica composite TPU fabrics is due to its unique material combination and advanced manufacturing process. Whether in terms of technical parameters or practical application effects, this fabric is ideal for tent manufacturing and can provide reliable protection in various complex environments.
