Overview of Chunyafang Composite TPU Fabric

Chunyasu composite TPU fabric is an innovative functional textile material, composed of springyasu substrate fabric and thermoplastic polyurethane (TPU) film through a special process. This fabric combines Chunyashi’s excellent drape and comfort, as well as the excellent waterproof and breathable properties of TPU membranes, showing unique advantages in the field of medical protection. Its basic structure includes three layers: the outer layer is a spring subtextile fabric that has been treated with water-resistant treatment, the middle layer is a high-performance TPU film, and the inner layer is a fiber material with good skin-friendly properties.

The key characteristics of this fabric are reflected in many aspects. First of all, it has excellent waterproof properties, which can effectively block liquid penetration while maintaining good breathability, ensuring that the wearer can maintain a comfortable somatosensory temperature and humidity during long use. Secondly, it has high mechanical strength, wear and tear resistance, and is especially suitable for protective clothing that requires frequent contact with various medical environments. In addition, the fabric has excellent chemical stability and can resist the erosion of a variety of disinfectants and detergents.

According to the new industry standards, the main technical parameters of Chunyafang composite TPU fabric are as follows:

These parameters ensure reliable performance of fabrics in complex medical environments. It is worth noting that this fabric has also passed a number of international certifications, including EN ISO 13688:2013 (Personal Protective Equipment-Basic Requirements for Clothing), EN 14126:2003 (Protective Clothing-Preventing Risk of Infection), etc., which fully proves that it is Applicability in the field of medical protection.

In recent years, with the continuous growth of global demand for medical protective products, the application scope of Chunyashi composite TPU fabrics is rapidly expanding. Especially in response to public health emergencies, this fabric has become indispensable in modern medical protection systems with its unique performance advantages.an important part of the

Technical characteristics and manufacturing technology of Chunyafang composite TPU fabric

The manufacturing process of Chunyashi composite TPU fabric adopts advanced multi-layer composite technology, mainly including three core links: base fabric preparation, coating treatment, and composite molding. During the preparation stage of the base cloth, high-quality polyester filaments are used as raw materials to produce a spring-spinned base cloth with a specific warp and weft density through a water spray weaving process. The base cloth has a delicate feel and good drape, providing an ideal carrier for subsequent composites.

In the coating treatment process, the TPU dispersion imported from Germany is used for precision coating. Through an automated controlled double-sided coating device, the TPU coating is evenly attached to the surface of the spring-spun substrate. This process requires strict control of the coating thickness and uniformity to ensure that the waterproof and breathable performance of the final product meets the design requirements. According to the research in literature [1], the optimal thickness range of the TPU coating is 10-20 microns. Too thick will affect the breathability, while too thin may lead to insufficient waterproofing performance.

Composite molding is the core step of the entire production process. High-temperature hot pressing composite technology is adopted to firmly combine the TPU film with the spring sub-spinned fabric. The specific process parameters are shown in Table 1:

Study shows that [2], appropriate hot pressing conditions can significantly improve the adhesive strength of the composite interface while keeping the functional characteristics of the TPU film undamaged. In order to further improve the overall performance of the fabric, functional additives such as antistatic agents and antibacterial agents will also be added during the composite process.

After, in the post-organization stage, the fabric is given better feel and dimensional stability through special calendering and shaping processes. At the same time, according to the needs of different application scenarios, functional organization such as ultraviolet ray protection and flame retardant can also be carried out. This series of strict process control ensures the outstanding performance of Chunyafang composite TPU fabrics in the field of medical protection.

The application advantages of Chunyafang composite TPU fabric in medical protective clothing

The application of Chunyafang composite TPU fabric in the field of medical protective clothing has shown significant advantages, especially in terms of protection performance, comfort and durability. According to the Centers for Disease Control and Prevention (CDC) evaluation report, the fabric has reached an international leading level in key protection indicators. Its main advantages are reflected in the following aspects:

First, in terms of protective performance, Chunyafang composite TPU fabric shows excellent barrier function. The strict ASTM F1670 blood penetration test shows that the fabric can effectively block the penetration of blood, body fluids and other infectious substances. At the same time, its antistatic properties comply with AATCC 76 standards, which can reduce the risk of particulate matter contamination caused by electrostatic adsorption. The following table shows the comparison data of this fabric with other common protective materials:

Secondly, in terms of comfort, the fabric achieves a perfect balance between waterproof and breathable. Research shows that [3], its unique microporous structure can block liquids while allowing water vapor molecules to pass smoothly, thus keeping the wearer dry and comfortable. Experimental data show that after 6 hours of continuous wear, the wearer’s skin humidity remains atWithin the appropriate range (relative humidity 40-60%), it is significantly better than traditional PVC coating materials.

In terms of durability, Chunya-style composite TPU fabrics show excellent mechanical properties. Through ISO 13934-1 tensile test, it shows that its fracture strength can reach more than 300N, far exceeding the standard requirements of medical protective clothing. In addition, the fabric has good wear resistance and tear resistance, and can maintain its original performance even after repeated cleaning and disinfection. According to the test results of European EN 14126 standard, the number of washes can reach more than 50 times, and the attenuation of various protective performance is less than 10%.
