Introduction

With the rapid development of the sportswear industry, consumers have increasingly demanded on the performance and durability of clothing. Although traditional nylon fabrics perform excellently in wear resistance and tensile strength, they still have certain limitations when facing complex environments and high-strength use. In order to break through this bottleneck, high-performance TPU (thermoplastic polyurethane) film composite nylon fabric came into being. This new material not only inherits the advantages of nylon fabric, but also further improves its physical performance and functionality through the addition of TPU film, making it an important part of modern sportswear.

TPU film is a polymer material with excellent elasticity and chemical resistance, which is widely used in various fields. It not only has good flexibility, tear resistance and wear resistance, but also maintains excellent mechanical properties in low temperature environments. Combining the TPU film with nylon fabric can significantly improve the overall performance of the fabric, especially in terms of water pressure resistance, breathability and wind resistance. In addition, the introduction of TPU film can enhance the antibacterial properties of the fabric and anti-ultraviolet ability, and extend the service life of the clothing.

This article aims to deeply explore the application and advantages of high-performance TPU film composite nylon fabrics in improving the durability of sportswear. Through detailed analysis of the material, including discussions on its manufacturing process, performance parameters, practical application cases and market prospects, we hope to provide valuable references to researchers and practitioners in related fields. At the same time, the article will cite research results from famous foreign literature to ensure the scientificity and authority of the content. Next, we will give a detailed introduction to high-performance TPU film composite nylon fabric from multiple angles.

Structure and characteristics of TPU film composite nylon fabric

The structural design of TPU film composite nylon fabric is the key to its excellent performance. This material usually consists of three layers: the outer layer is nylon fabric, the middle layer is TPU film, and the inner layer is different types of fabrics or coatings can be selected according to the specific needs. This sandwich-style structural design not only improves the overall strength of the fabric, but also gives it a variety of functional characteristics, making it outstanding in different application scenarios.

1. Outer layer: nylon fabric

Nylon fabric, as an outer material, is mainly responsible for providing basic mechanical properties and appearance texture. Nylon fibers have high strength, low density and good wear resistance, and can maintain stable shape during long-term use. In addition, nylon fabrics also have good dyeing and processability, and can be customized to produce according to different design needs. Common types of nylon fibers include PA6, PA66, etc., which have their own characteristics in terms of mechanical properties and chemical resistance.

2. Intermediate layer: TPU film

TPU film is the core part of the TPU film composite nylon fabric, and its thickness is generally between 0.1 mm and 0.3 mm. TPU materials have excellent elasticity, wear resistance and chemical resistance, and can effectively resist erosion from the external environment. In addition, the TPU film also has good moisture permeability and waterproofness, so that the fabric remains dry and comfortable in humid environments. The main components of TPU film include polyester TPU and polyether TPU, which have different performances:

3. Inner layer: additional fabric or coating

The selection of inner layer materials depends on the specific use scenario and functional requirements. For example, in outdoor sportswear, the inner layer can be made of moisture-wicking polyester fiber to improve wear comfort; while in waterproof jackets, a hydrophilic coating can be added to the inner layer to further enhance waterproofing. Effect. The diversity of inner layer materials enables TPU film composite nylon fabrics to meet a variety of complex application needs.

Through the above three-layer structure design, the TPU film composite nylon fabric not only has excellent mechanical properties, but also achieves the integration of multiple functions. This innovative combination of materials brings unprecedented durability and functionality to sportswear, making it stand out from the fierce market competition.

Manufacturing process and technical difficulties

The manufacturing process of TPU film composite nylon fabric is relatively complex, involving multiple key steps and technical difficulties. First, the selection and pretreatment of raw materials is crucial. The quality of nylon fiber and TPU film directly affects the performance of the final product, so strict screening of high-quality materials is required. oftenThe nylon fibers used include PA6 and PA66, while the TPU film is divided into polyester and polyether types, each of which has its own unique properties.

1. Raw material selection and pretreatment

In the process of material selection, factors such as the tensile strength, elongation of break and wear resistance of the fiber must be considered. After the nylon fiber is spinning, drafting and shaping, it forms a yarn with certain specifications. These yarns are then made into fabrics by knitting or knitting. The TPU film needs to undergo melt extrusion, cooling and shaping steps to ensure that its thickness is uniform and the surface is smooth. The pretreatment also involves surface modification of the fabric and the TPU film to improve the adhesion of the two. For example, using plasma treatment or electroless coating methods can significantly enhance the interface binding force.

2. Composite process

Composite process is the core link in the manufacturing of TPU film composite nylon fabrics. At present, there are two main composite methods: hot pressing composite and coating composite. The hot pressing composite makes the TPU film closely fit with the nylon fabric through heating and pressing. This method is suitable for thicker TPU films, but it is difficult to operate and is prone to bubbles or layering. The coating composite is to uniformly coat the liquid TPU resin on the surface of the nylon fabric, and then cure the film to form. This method is simple in technology and is suitable for large-scale production, but has high requirements for equipment accuracy.

3. Technical difficulties and solutions

The main technical difficulties faced in the manufacturing process include poor interface bonding, poor dimensional stability and cost control. To address these problems, researchers have proposed a variety of solutions. For example, using a multi-layer composite structure, that is, adding an intermediate layer with good bonding properties between the TPU film and the nylon fabric, such as polyurethane adhesive or hot melt adhesive mesh, can effectively improve the interface bonding force. In addition, by optimizing production process parameters, such as temperature, pressure and time, the dimensional stability and consistency of the finished product can be improved. Later, in terms of cost control, it is possible to reduce production costs and improve economic benefits by improving production equipment and optimizing process flow.

To sum up, the manufacturing process of TPU film composite nylon fabric involves multiple key technical links, each link needs to be precisely controlled and optimized. Only by solving these technical problems can we ensure productionThe quality and performance of the product can be stable, so as to better meet market demand.

Performance Parameter Comparison

In order to more intuitively demonstrate the advantages of TPU film composite nylon fabric compared to traditional nylon fabrics, we can compare and analyze them from multiple performance parameters.

Abrasion resistance is an indispensable feature of sportswear. According to the Journal of Materials Science, the wear resistance of TPU film composite nylon fabric is about 30% higher than that of ordinary nylon fabrics. This is because the addition of the TPU film enhances the wear-resistant layer on the surface of the fabric and effectively reduces frictional damage.

3. Breathability

Breathability determines the comfort of wearing. A paper in the journal Polymer Testing pointed out that TPU film composite nylon fabric has better breathability than ordinary nylon fabrics. Although the TPU film itself has a certain barrier effect, its microporous structure and special coating design ensure air circulation, thereby improving overall breathability.

4. Waterproof

Waterproofing is especially important for outdoor sports. According to the research of Journal of Applied Polymer Science, the waterproof performance of TPU film composite nylon fabric has been greatly improved, with its hydrostatic pressure value up to 10,000 mmH₂O, while ordinary nylon fabric is only 3,000 mmH₂O. This shows that the addition of TPU film significantly enhances the waterproof barrier of the fabric.

To sum up, TPU film composite nylon fabric is better than traditional nylon fabric in terms of performance parameters such as tensile strength, wear resistance, breathability and water resistance. These data not only show the superiority of new materials, but also provide scientific basis for the design of sportswear. In the future, with the continuous advancement of technology, TPU film composite nylon fabrics are expected to be widely used in more fields.
