Anti-slip shock absorption technology of TPE three-layer composite fabric in gardening tool protective cover
Introduction
With the continuous development of the horticulture industry, the requirements for tools are becoming higher and higher. In order to improve work efficiency, protect user safety and extend the service life of the tool, the selection of protective cover material for gardening tools is particularly important. As a new composite material, TPE (thermoplastic elastomer) is increasingly widely used in gardening tool protective covers. This article will introduce in detail the anti-slip shock absorption technology of TPE three-layer composite fabric in gardening tool protective covers, and combine product parameters, experimental data and famous foreign literature to explore its advantages and application prospects.
Introduction to TPE three-layer composite fabric
TPE is a new material between rubber and plastic, with good elasticity and processing properties. The three-layer composite structure is usually composed of an outer wear-resistant layer, an intermediate buffer layer and an inner adhesive layer. This structure not only improves the overall performance of the material, but also gives it its unique anti-slip shock absorption characteristics.
| Hydraft | Materials | Function |
|---|---|---|
| External layer | TPU | Provides wear and tear resistance |
| middle | EVA | Provides cushioning and shock absorption |
| Inner layer | PVC | Provides adhesion and sealing |
Anti-slip technology
-
Surface treatment technology
- The outer layer of TPE three-layer composite fabric is made of TPU material, which can significantly increase the friction coefficient after special surface treatment. According to standard tests from the American Association for Materials and Testing (ASTM), the static friction coefficient of this material can reach more than 0.75, which is much higher than that of traditional rubber materials.

-
Micropore structure design
- Introducing microporous structures into TPE materials can effectively increase the contact surfacethe roughness of the friction. Studies have shown that the design of the micropore structure increases the friction coefficient by about 30%.

Shock Absorbing Technology
-
Multi-layer buffer structure
- The intermediate layer of TPE three-layer composite fabric is made of EVA material, which has excellent cushioning performance. Through multiple impact experiments, it was found that the material can absorb up to 80% of the impact energy and effectively reduce vibration transmission.

-
Dynamic response analysis
- Using the finite element analysis method (FEA), dynamic response simulation is performed on TPE three-layer composite fabric. The results show that the damping ratio of this material under high-frequency vibration is 0.15, indicating that it has good shock absorption effect.
