Introduction to TPU composite silver fox fur fabric
TPU composite silver fox sued fabric is a high-performance functional fabric integrating waterproof, breathable and warm performance, and is widely used in high-end sports equipment. Its core material is thermoplastic polyurethane (TPU), which combines advanced composite technology with silver fox velvet fibers to form a fabric structure that combines soft touch and excellent functionality. This fabric not only has excellent waterproof performance, effectively resists external moisture intrusion, but also has excellent breathability, ensuring that the wearer remains dry and comfortable during high-intensity exercise. In addition, the unique structure of the silver fox velvet fiber gives the fabric excellent warmth, making it ideal for outdoor sports in cold climates.
The core advantage of TPU composite silver fox fabric is its versatility and durability. It perfectly combines TPU film with silver fox velvet fiber through multi-layer composite process, achieving a balance between waterproof, breathable and warmth. This feature makes it widely used in professional sports equipment such as ski suits, mountaineering suits, running suits, etc. For example, in ski scenes, TPU composite silver fox velvet fabric can effectively isolate the penetration of snow water, and at the same time release internal moisture through the microporous structure to avoid discomfort caused by sweat accumulation; while in high-altitude mountaineering activities, its warmth can be achieved Help athletes with extreme low temperatures.
From the market demand, with the growth of global consumers’ demand for functional sportswear, the application prospects of TPU composite silver fox fur fabric are very broad.

Especially in the European and American markets, high-end sports brands such as The North Face, Arc’teryx and Patagonia have regarded this type of fabric as an important part of their core product lines, further promoting the popularization of the market and technological upgrades.
To sum up, TPU composite silver fox fur fabric has become an indispensable key material in the field of modern sports equipment due to its unique physical characteristics and a wide range of application scenarios. Next, we will explore in-depth the specific key points of its waterproof and breathable technology and its performance in practical applications.
Basic Principles of Waterproof and Breathable Technology
The waterproof and breathable performance of TPU composite silver foxsui fabric mainly depends on the microstructure design of TPU film and the wet conduction characteristics of silver foxsui fiber. Specifically, the TPU film realizes the dual functions of waterproof and breathable through the microporous structure, while the silver fox velvet fiber enhances the overall humidity management capability with its natural fiber channels. The technical principles of these two parts will be analyzed in detail below.
1. Microporous structure and waterproof and breathable mechanism of TPU film
The core of the TPU film is its unique micropore structure, which are usually smaller than 1 micron (μm) in diameter and are much smaller than the size of the water droplets (about 20-50μm), but larger than the size of the water vapor molecule (about 0.0004μm). Based on this size difference, the TPU film can prevent liquid water from penetration while allowing water vapor to pass through, thereby achieving waterproof and breathable effect. This “selective permeability” characteristic comes from the synergistic effect of capillary action and surface tension: when liquid water contacts the surface of the film, due to the strong cohesion between the water molecules, it is impossible to enter the micropores; while water vapor molecules are small due to their small size And the kinetic energy is high, and it can smoothly pass through the micropores and diffuse to the external environment.
In addition, the waterproof performance of TPU film is closely related to its thickness. Studies have shown that thinner TPU films have higher breathability efficiency, but may also reduce the waterproofing level. Therefore, in actual production, it is necessary to optimize the film thickness according to the specific application scenarios to achieve an optimal balance between waterproofing and breathability. For example, the TPU film used in ski suits is usually 20-30μm thick, providing waterproofing levels up to 20,000mm (i.e., it can withstand the pressure of a 20-meter-high water column without leakage), while maintaining good breathability (>5,000g /m²/24h).
2. Wet conduction characteristics and humidity management of silver fox velvet fiber
Silver fox velvet fiber, as a natural fiber, has excellent moisture absorption and sweating properties. There are a large number of fine grooves on the surface of its fibers, which can quickly absorb and conduct sweat emitted by the human body through capillary action, guiding it to the outer layer to evaporate. This efficient humidity management system not only improves the wearer’s comfort, but also further improves the breathable performance of the TPU film. Because when sweat is quickly discharged, the pressure difference inside the TPU film will be significantly reduced, thereby reducing the water vapor diffusion resistance.
It is worth noting that the moisture absorption capacity of silver fox velvet fiber is not infinite, and its large moisture absorption rate is usually 30%-40% of its own weight. Once this threshold is exceeded, the fiber may lose its moisture conduction function, causing moisture retention. Therefore, when designing TPU composite silver foxsui fabrics, additional functional coatings or treatment processes are often added to enhance the fiber’s moisture resistance.
3. Comprehensive performance analysis
In order to better understand the waterproof and breathable principle of TPU composite silver fox sued fabric, the following lists the key parameters and their corresponding functions:
| parameter name | Unit | Description of meaning |
|---|---|---|
| Waterproof Grade | mm H₂O | Denotes the height of the large water column that the fabric can withstand. The higher the value, the stronger the waterproof performance |
| Breathable | g/m²/24h | The water vapor mass allowed to pass every 24 hours per square meter of fabric, the higher the value, the better the breathable performance, the better the air permeability |
| Micropore density | Hole/cm² | The number of micropores in TPU film per unit area directly affects breathability efficiency |
| Fiber Hygroscopic Rate | % | The proportion of moisture that silver fox velvet fiber can absorb to its own weight |
Combined with the above parameters, it can be found that the waterproof and breathable performance of TPU composite silver fox fur fabric is determined by multiple factors. For example, higher micropore density and breathability help improve the overall breathability of the fabric, but may slightly sacrifice waterproof performance; while stronger fiber moisture absorption can effectively alleviate the problem of moisture accumulation, but attention should be paid to controlling moisture absorption. Upper limit.
The famous foreign document “Textile Research Journal” once published a study pointing out that the micropore morphology of TPU films has a significant impact on its performance. Through scanning electron microscopy (SEM), the research team found that TPU films with uniformly distributed and regular-shaped micropore structures showed better waterproof and breathable properties. This provides an important reference for the subsequent optimization of the design of TPU composite silver fox fur fabric.
Fabric Processing Technology and Technical Points
The processing process of TPU composite silver fox fur fabric is complex and fine, involving multiple key steps and technical details to ensure that the waterproof and breathable performance of the final product meets the expected standards. The following are the detailed processing process and technical points of each link.
1. Raw material preparation and pretreatment
The basic materials of TPU composite silver foxsui fabric include TPU film and silver foxsui fiber. Before processing, these two materials must be strictly screened and pretreated. The choice of TPU films requires consideration of their thickness, hardness and durability. High molecular weight TPU materials are usually used to ensure their mechanical strength and chemical stability. Silver fox velvet fiber needs to undergo pretreatment processes such as degreasing, bleaching and dyeing to remove impurities and improve its surface performance.
Technical Points:
- TPU film thickness control: The film thickness should be adjusted according to the specific purpose, and the general range is 10-50μm. Too thick will lead to a decrease in breathability, while too thin may affect waterproofing.
- Silver Fox Fur Fiber Pretreatment Parameters:
- Degreasing temperature: 60-80°C
- Bleach concentration: 3-5%
- Staining time: 30-60 minutes
2. Composite process
TPThe core manufacturing link of U composite silver foxsui fabric is the composite process, that is, combining TPU film and silver foxsui fiber through hot pressing or adhesive. This process requires precise control of parameters such as temperature, pressure and time to ensure a firm bond between the two layers of materials.
| Process Parameters | Recommended Value | Technical Note |
|---|---|---|
| Temperature | 120-150°C | A suitable temperature can promote TPU softening and enhance adhesion |
| Suppressure | 3-5kg/cm² | Excessive pressure may cause film deformation and affect breathable performance |
| Time | 10-20 seconds | Enough time to ensure full bonding, but it should not be too long to avoid damage to the fiber |
In addition, functional coatings, such as hydrophobic coatings or antibacterial coatings, can be introduced in the composite process to further enhance the overall performance of the fabric.
3. Post-organization processing
After the composite is completed, the fabric needs to undergo a series of post-organization processes, including shaping, wrinkle prevention and functional treatment. These steps are designed to optimize the feel, appearance and functionality of the fabric.
- Styling treatment: Keep the fabric flat by high-temperature ironing while fixing the structure between the composite layers.
- Anti-wrinkle treatment: Use resin coating technology to impart wrinkle-resistant properties to the fabric.
- Functional treatment: such as adding anti-ultraviolet coatings, anti-static coatings, etc. to meet specific usage needs.
4. Quality inspection
After
, the finished fabric needs to undergo strict quality inspection to ensure that it complies with relevant standards. The main testing items include waterproofing grade, breathability, tensile strength and wear resistance.
| Detection items | Standard Requirements | Test Method |
