Principles and application status of thermal bonding technology
Thermal bonding technology is an advanced manufacturing process that combines materials of different materials through heating and pressurization. This technology plays a crucial role in the production of jacquard stretch fabric composite TPU fabrics. The basic principle is to use the bonding properties generated by the material at high temperatures to make two originally incompatible materials closely connected together to form a composite material with strong integrity and diverse functions.
According to the famous foreign literature “AdvAccording to the description of anced Textile Composites, thermal bonding technology is mainly divided into two methods: direct thermal bonding and indirect thermal bonding. Direct thermal bonding refers to the placement of two layers of materials directly in a hot press and bond under specific temperature and pressure conditions; indirect thermal bonding requires the use of adhesive or special coating as interposer to enhance the bonding. Effect. These two methods have their own advantages and disadvantages, and the choice depends on the specific application requirements and material characteristics.
At present, the application of thermal bonding technology in jacquard elastic cloth composite TPU fabrics is very mature. According to a review article in Textile Research Journal, more than 70% of high-end sportswear brands worldwide use this technology to produce their products. These brands include internationally renowned companies such as Nike and Adidas. The fabrics produced by using thermal fitting technology not only improve the functionality and durability of the product, but also significantly improve the wearing experience.
However, although the technology is relatively mature, there are still some challenges in practical applications. For example, how to balance the difference in thermal expansion coefficients between materials to avoid stratification, and how to reduce energy consumption while ensuring strength are all the key directions of current research. In response to these problems, many companies and scientific research institutions are actively carrying out technological innovations, striving to further optimize the thermal bonding process.
The following are several common thermal bonding technical parameters and their impact:
| parameters | Description | Influencing Factors |
|---|---|---|
| Temperature | Control the softening point of the material to ensure full bonding | Material type, thickness |
| Suppressure | Provide enough physical contact to promote intermolecular action | Equipment capability, material toughness |
| Time | Determines the degree of bonding and uniformity | Production efficiency, quality control |
| Surface treatment | Improve interface compatibility and increase binding strength | Material surface properties, pretreatment technology |
By continuously optimizing these parameters, not only can the comprehensive performance of the product be improved, but the production cost can also be reduced, thereby enhancing market competitiveness. Therefore, in-depth research and mastering the principles and current application status of thermal bonding technology is of great significance to promoting the development of the textile industry.
Detailed explanation of the thermal bonding process parameters of jacquard elastic cloth composite TPU fabric
The success of the thermal bonding process is not straightIt affects the quality and performance of Jacquard elastic cloth composite TPU fabric. To ensure optimal bonding, a number of key process parameters must be precisely controlled, including temperature, pressure, time, and surface treatment. The following will introduce the role of these parameters and their impact on the quality of the final product.
Temperature Control
Temperature is one of the important parameters in the thermal bonding process, because it directly affects the melting state and bonding properties of the TPU film. Typically, the melting point of the TPU film is between 180°C and 220°C. According to the research of Polymer Processing Science, too low temperatures may cause the TPU to fail to completely soften, which affects the bonding strength; while too high temperatures may damage the fiber structure of the jacquard elastic cloth, causing the fabric to lose its original elasticity and feel . Therefore, it is crucial to choose the right temperature range.
| Temperature range (°C) | Result Description |
|---|---|
| <180 | TPU is not fully softened and binding is insufficient |
| 180-220 | Best bonding effect, stable material performance |
| >220 | Damage fabric fibers and reduce fabric elasticity |
Pressure setting
Pressure parameters determine the degree of physical contact between the two layers of materials, which in turn affects the uniformity and firmness of the bond. Generally speaking, the pressure range during thermal bonding should be maintained between 3 and 5 MPa. Too low pressure will lead to a large gap between the materials, affecting waterproofing performance; whereas too high pressure may compress the fabric fibers, change their original structure, and affect the breathability and elasticity of the fabric.
| Pressure Range (MPa) | Result Description |
|---|---|
| <3 | More spaces, weak binding force |
| 3-5 | Best bonding effect, stable material performance |
| >5 | Fabric compression affects breathability and elasticity |
Time Management
The time parameter involves the duration of the thermal bonding process, which together with temperature and pressure determines the effect of bonding. Generally speaking, the time for thermal fit should be 1Between 0 and 30 seconds. Shorter time may cause the TPU to fail to melt sufficiently, affecting the bonding strength; while excessive time may increase energy consumption and may cause material damage due to excessive heating.
| Time range (seconds) | Result Description |
|---|---|
| <10 | TPU is not fully melted and binding force is insufficient |
| 10-30 | Best bonding effect, stable material performance |
| >30 | Overheating may damage the material |
Surface treatment
Surface treatment refers to pretreating the surface of a material before thermal bonding to improve its bonding properties. Commonly used surface treatment methods include corona treatment, plasma treatment and chemical treatment. These methods can effectively improve the roughness and polarity of the material surface, thereby enhancing the bonding force between the TPU film and the jacquard elastic cloth. According to Surface and Coatings Technology, the bonding strength of materials with appropriate surface treatment can be increased by 20% to 30%.
| Processing Method | Effect description |
|---|---|
| Corona treatment | Improve surface energy and enhance bonding performance |
| Plasma treatment | Improve surface roughness and increase bonding area |
| Chemical Treatment | Change surface chemistry and improve binding strength |
To sum up, by precisely controlling the four key parameters of temperature, pressure, time and surface treatment, the thermal bonding effect of jacquard elastic cloth composite TPU fabric can be significantly improved, thereby ensuring high quality and high performance of the product.
Process Optimization Strategies and Case Analysis
In the production process of jacquard elastic cloth composite TPU fabric, process optimization is a key link in ensuring product quality and improving production efficiency. By adjusting the specific parameters of thermal bonding technology, important indicators such as bonding strength, waterproof performance and breathability of the material can be significantly improved. The following will discuss the specific optimization strategies in detail from three aspects: equipment improvement, parameter adjustment and application of new materials, and explain them in combination with actual cases.
Equipment Improvement
First, the upgrade of equipment is crucial to optimize the thermal bonding process. The modern hot press is equipped with a precise temperature control system and pressure adjustment device, which can more accurately control the temperature and pressure parameters during the thermal bonding process. For example, an internationally renowned textile company introduced a German-made intelligent hot press, which has real-time monitoring and automatic adjustment functions, making the thermal bonding process more stable and reliable. According to the company’s report, after the equipment upgrade, the product’s pass rate increased by 15%, while the production cycle was shortened by about 20%.
Parameter adjustment
Secondly, by carefully adjusting the key parameters during the thermal bonding process, the bonding effect of the material can be significantly improved. For example, according to a study in Journal of Applied Polymer Science, appropriately reducing the thermal bonding temperature to about 200°C and extending the bonding time to 25 seconds can significantly improve the TPU film without affecting the elasticity of the material Combination strength with jacquard stretch cloth. In addition, experimental data show that when the pressure is set at 4.5 MPa, it can achieve optimal waterproofing and breathable balance.
| Parameter adjustment | Result Description |
|---|---|
| Temperature drops to 200°C | Enhance the bonding strength and reduce material damage |
| Time extends to 25 seconds | Improving waterproofing and breathability |
| Pressure is set to 4.5 MPa | Achieving optimal performance balance |
New Material Application
After
, the use of new materials is also one of the important means of optimizing the process. In recent years, nano-scale TPU coatings have attracted widespread attention for their excellent mechanical properties and environmentally friendly properties. A Japanese textile company introduced this new material on its production line and found that it can not only enhance the wear resistance of the fabric, but also effectively reduce energy consumption during the thermal bonding process. Specific data show that after using nano-scale TPU coating, energy consumption per unit area was reduced by about 12%, while the durability of the product was improved by nearly 20%.
Through the above-mentioned equipment improvement, parameter adjustment and specific measures for the application of new materials, not only the overall performance of jacquard elastic cloth composite TPU fabric has been improved, but also greatly reduced production costs and energy consumption, laying a solid foundation for the sustainable development of the enterprise.
