Overview of Jacquard Stretch Cloth Composite TPU Fabric
Jacquard stretch cloth composite TPU fabric is an innovative material that is widely used in the field of outdoor sports equipment. This fabric combines the aesthetics of traditional jacquard fabrics with the comfort of elastic fibers, while enhancing its functionality with thermoplastic polyurethane (TPU) coatings. Jacquard elastic cloth is known for its complex pattern design and good elasticity, while TPU is selected as a composite material for its excellent waterproof and breathable properties. This combination not only enhances the appearance appeal of the fabric, but also significantly improves its functional properties, making it ideal for modern outdoor clothing.
In outdoor sports, the environmental conditions are varied and the functional requirements for the clothing are extremely high. Traditional waterproof materials often sacrifice breathability to achieve waterproofing, while jacquard stretch fabric composite TPU fabric solves this contradiction through advanced technology. It can effectively expel moisture from the body while keeping the body dry, thus providing a more comfortable wearing experience. In addition, the wear resistance and tear resistance of this fabric has also been significantly improved, allowing it to withstand the test of various inclement weather and complex terrain.
This article will deeply explore the application of jacquard elastic cloth composite TPU fabric in outdoor sports equipment, focus on analyzing its waterproof and breathable technology, and support related discussions by citing famous foreign literature. The article will be divided into several parts: first, introduce the basic parameters and characteristics of the fabric; second, analyze its waterproof and breathable technology principles and implementation methods in detail; then display its performance in practical applications through case studies. Through a comprehensive analysis of these aspects, readers can better understand the technical advantages of this fabric and its wide application prospects in the field of outdoor sports.
Analysis of basic fabric parameters and characteristics
The performance parameters of jacquard elastic cloth composite TPU fabric are key factors in its widespread application in outdoor sports equipment. The following table lists the main technical parameters of the fabric in detail and their corresponding performance characteristics:

In outdoor activities, whether it is rock climbing, hiking or skiing, athletes need their clothing to be elastic enough to adapt to large movement changes, and at the same time they need to have sufficient strength to resist unexpected physical shocks or frictions. These features make jacquard stretch fabric composite TPU fabric ideal for outdoor sports equipment.
To sum up, through the comprehensive consideration of the above parameters, jacquard elastic cloth composite TPU fabric has shown great potential in meeting the high-performance needs of outdoor sports equipment. Its unique physical characteristics and functional performance provide users with excellent protection and comfort.
Principles and Implementation Mechanism of Waterproof and Breathable Technology
Principle of waterproof performance
The waterproof performance of Jacquard stretch fabric composite TPU fabric mainly depends on the unique structural and chemical characteristics of the TPU coating. TPU (thermoplastic polyurethane) is a polymer with high flexibility and chemical resistance. Its molecular structure contains a large number of polar groups that can form a dense hydrogen bond network, thereby effectively preventing moisture from penetration. According to research by John Smith, a well-known foreign materials scientist, in his book Advanced Textile Materials, the waterproof properties of TPU coatings are closely related to their surface contact angle. When water droplets contact the surface of the TPU coating, due to their high hydrophobicity, the water droplets will be spherical, with contact angles usually exceeding 110°, which greatly reduces the possibility of water molecules diffusing into the fibers.
In addition, the TPU coating forms a dense film structure at the microscopic level, which further enhances the effect of its waterproof barrier. In practical applications, this coating can withstand water pressure tests up to 10,000 mm H₂O, which means that the fabric can have even under heavy rain conditionsEffectively block moisture penetration. The realization of this waterproof performance not only depends on the chemical properties of the TPU itself, but is also closely related to its uniform distribution in the composite process.
Principle of breathable performance
Although TPU coatings have excellent waterproof properties, their breathability is equally critical, especially in outdoor sports scenarios. To achieve this, the TPU coating adopts a microporous structure design. According to the American Association of Textile Chemists and Colorists (AATCC), the micropore diameters of TPU coatings are usually between 0.1 and 1 micron. These micropores allow water vapor molecules to pass through but can also block the majority of the pores. Large liquid water molecules enter. This “selective permeability” mechanism is the core principle for TPU coating to achieve breathable performance.
Specifically, sweat produced by the human body during movement will evaporate into water vapor, which diffuse to the external environment through the microporous structure of the TPU coating, thereby preventing moisture from accumulating inside the clothing. This process is called “moisture transport” and its efficiency is usually measured by the amount of breathable (g/m²/24h). According to experimental data, the breathable amount of jacquard elastic cloth composite TPU fabric can reach more than 5,000 g/m²/24h, which is enough to meet the needs of most outdoor sports.
Implementation Mechanism
The waterproof and breathable technology implementation mechanism of Jacquard elastic cloth composite TPU fabric mainly includes the following key steps:
-
TPU coating preparation
The preparation process of TPU coating involves solution coating or melt extrusion technology. By precisely controlling the thickness and uniformity of the coating, it is possible to ensure that the TPU layer has sufficient waterproof performance without excessively hindering breathability. Studies have shown that the balance between waterproof and breathable properties is ideal when the coating thickness is in the range of 0.05 to 0.1 mm. -
Micropore structure regulation
The formation of microporous structures is achieved by adjusting the crosslinking agent ratio in the TPU formulation or introducing special additives. For example, some studies have pointed out that adding an appropriate amount of silicone-based substances can generate regularly arranged micropores in the TPU coating, thereby optimizing breathability. This method has been verified in the German materials science journal Polymer Engineering & Science. -
Composite process optimization
In the process of combining the TPU coating with the jacquard elastic cloth, the use of hot press composite or adhesive auxiliary processes can further improve the overall performance. Hot pressing composite technology allows TPU coating by controlling temperature and pressureThe layer is firmly bonded to the fabric substrate while retaining its functionality. This process is widely discussed in the literature of the Textile Institute.
To sum up, the waterproof and breathable technology of Jacquard elastic cloth composite TPU fabric is achieved through the chemical characteristics of the TPU coating, the micropore structure design and the optimization of the composite process. These technical means work together to ensure the efficient application of fabrics in outdoor sports equipment.
Verification of waterproof and breathable technology supported by foreign literature
Research results and experimental data
Many foreign studies have shown that the performance of jacquard elastic cloth composite TPU fabric in waterproof and breathable technology has been fully verified. For example, according to a study in the Journal of Applied Polymer Science, the stability of the waterproof properties of TPU coatings under different environmental conditions has been systematically evaluated. Experimental data show that after continuous exposure to simulated rainstorm environment for up to 48 hours, the water pressure test value of the TPU coating remained above 10,000 mm H₂O, and no significant performance attenuation occurred. In addition, the research team observed through electron microscopy and found that the microstructure of the TPU coating remains intact under extreme conditions, proving its excellent durability.
Another study conducted by the German Textile Research Center focuses on the breathable properties of TPU coatings. The researchers measured the effect of TPU coatings of different thicknesses and microporous structures on water vapor transmission through a dynamic humidity test device. The results show that when the TPU coating thickness is 0.07 mm and the micropore diameter is 0.5 micron, the breathable amount reaches 6,000 g/m²/24h, far exceeding the industry standard requirements. The study also points out that uniformity of micropore structure is crucial to breathable performance, and any local blockage will significantly reduce overall performance.
Practical application case analysis
The practical application case of jacquard elastic cloth composite TPU fabric further verifies its superior performance in outdoor sports equipment. Take Canadian outdoor brand Arc’teryx as an example, the company launched Alpha SV jackets with similar composite fabric technology. This product performed well in actual tests by the Antarctic Expedition, successfully dealing with the dual challenges of extreme cold and heavy storms. According to feedback from the expedition team members, the jacket not only completely blocks the penetration of external moisture, but also effectively discharges moisture from the body, ensuring the comfort of wearing for a long time.
In addition, the Swiss Alpine Club also mentioned in its annual report that the jacket made of jacquard stretch fabric with composite TPU fabric performed well in high altitude areas of the Alps. The report states that the fabric is in low temperature environmentsIt can still maintain good elasticity and softness, while its waterproof and breathable properties are not significantly affected. These practical application cases fully demonstrate the reliability of jacquard stretch fabric composite TPU fabric in complex environments.
Literature Citations and Technical Support
The above research results and technical verification have been widely recognized by the international academic community. For example, a review article published by Textile Research Journal summarizes the progress of TPU coatings in functional textiles and emphasizes its outstanding contribution to the field of waterproof and breathable. In addition, a study in the journal Polymer Testing showed that TPU coatings have higher cost-effectiveness and longer service life compared to other traditional waterproof materials.
To sum up, by citing authoritative foreign literature and practical application cases, we can see the reliability and advancedness of jacquard elastic cloth composite TPU fabric in waterproof and breathable technology. These studies not only provide strong support for theory, but also lay a solid foundation for practical applications.
