Optimization of elastic recovery technology of TPE three-layer composite fabric in sports goods

Abstract

This article mainly discusses the elastic recovery technology optimization of TPE (thermoplastic elastomer) three-layer composite fabric in sports goods. By analyzing the existing technology, studying material characteristics, and citing famous foreign literature, the application of TPE composite fabrics in sports equipment and their performance improvement methods are introduced in detail. The article covers product parameters, experimental data, market status and future development trends, and uses tables to present key information to improve readability and practicality.

Introduction

With the development of modern technology, the demand for high-performance materials in the sports goods industry is growing. TPE three-layer composite fabrics have been widely used in sportswear, footwear and other sports equipment due to their excellent elasticity and durability. However, how to further optimize its elastic recovery ability and better adapt to high-intensity exercise needs has become one of the focus of current research.

Introduction to TPE three-layer composite fabric

TPE is a polymer material that combines rubber and plastic properties, with good flexibility, wear resistance and tear resistance. The three-layer composite structure is usually composed of an outer layer, an intermediate layer and an inner layer. The selection of materials of each layer directly affects the performance of the final product. The following is the basic composition of TPE three-layer composite fabric:

Product parameters and performance indicators

To evaluate the performance of TPE three-layer composite fabrics, some important parameters and test methods are listed below:

Elastic recovery technology optimization solution

1. Material selection optimization

   • High-strength TPE elastomer: Choose TPE materials with higher elastic modulus and lower permanent deformation rate, such as products from brands such as Santoprene and Versaflex.
   • Nanointensifier: Adding nanoscale fillers (such as carbon nanotubes or graphene) can significantly improve the mechanical properties and durability of TPE.

2. Production process improvement

   • Twin screw extrusion molding: Use a twin screw extruder for continuous production to ensure that the materials of each layer are evenly distributed and the interface is firmly combined.
   • Low-temperature curing treatment: By controlling the curing temperature and time, reduce shrinkage and deformation caused by thermal stress, thereby improving the dimensional stability and elastic recovery ability of the finished product.

3. Surface Modification Treatment

   • Plasma treatment: Use low-temperature plasma to activate the TPE surface to increase its hydrophilicity and adhesion, which is conducive to subsequent coating or other functional treatments.
   • Electric coating: Coating a thin and tough polymer film can not only protect the internal structure from the external environment, but also give the fabric additional functional properties (such as waterproofing and resistant to water)bacteria, etc.).

Experimental verification and data analysis

By conducting a series of physical and chemical tests on TPE three-layer composite fabric samples under different formulation and process conditions, we obtained the following results:

From the table above, it can be seen that the optimized sample C shows better overall performance, especially in terms of elastic recovery and moisture transmission.

Market status and prospects

There is currently a growing demand for high-performance sports fabrics worldwide, especially those that provide excellent elastic recovery characteristics. According to Grand View Research, the global sportswear market is expected to reach around US$45 billion by 2027. Among them, TPE composite fabrics occupy an important position in the high-end market with their unique advantages.

In the future, with the continuous emergence of new materials and new technologies, TPE three-layer composite fabrics are expected to make breakthroughs in the following aspects:

• Lighter design;
• Higher durability and comfort;
• More environmentally friendly and sustainable production process.

Conclusion

To sum up, by systematically optimizing the elastic recovery technology of TPE three-layer composite fabrics, it can not only significantly improve its physical performance, but also meet the increasingly stringent requirements of athletes for high-quality sports equipment. At the same time, this also brings new development opportunities to related companies andMarket competitive advantage.
