Study on the breathability technology of SBR diving composite fabrics to improve the sultry feeling of divers
Abstract
SBR (Styrene-Butadiene Rubber) composite fabrics have wide applications in modern diving suits. However, traditional SBR materials have poor breathability, which causes divers to feel stuffy and uncomfortable during long-term use. This paper studies the breathability improvement technology of SBR composite fabrics and discusses how to effectively improve their breathability performance and thus improve the wear experience of divers. The article introduces the basic parameters and breathability testing methods of SBR composite fabrics in detail, and cites many famous foreign literature for theoretical support. In addition, the effects of different breathability improvement technologies are compared in the form of a table to provide reference for researchers and practitioners in related fields.
1. Introduction
Diving is a highly equipment-demanding sport where the performance of diving suits is crucial as a key equipment to protect divers from cold water temperatures. Although traditional SBR composite fabrics have good water resistance and durability, they perform poorly in breathability, which can easily cause divers to feel stuffy and affect their comfort and work efficiency. Therefore, how to improve the breathability of SBR composite fabrics has become an urgent problem. This study aims to improve the breathable performance of SBR composite fabrics through technological innovation and material optimization, in order to provide divers with a more comfortable wearing experience.
2. Basic parameters of SBR composite fabric
| parameter name | Unit | value |
|---|---|---|
| Density | g/cm³ | 1.20 |
| Elastic Modulus | MPa | 50 |
| Tension Strength | MPa | 30 |
| Elongation | % | 400 |
| Watert Tightness | Pa | >100,000 |
3. Breathability testing method
In order to accurately evaluate the breathable properties of SBR composite fabrics, the following common test methods are adopted in this paper:
- Gas permeation method: Use a gas permeation meter to measure a unit time to pass a one-way passThe amount of gas of a material in a fixed area.
- Moisture Evaporation Method: Evaluate its breathable performance by measuring the humidity difference on both sides of the material.
- Temperature gradient method: Set different temperature gradients to observe the breathability changes of the material.
These test methods can comprehensively evaluate the breathability of SBR composite fabrics from different angles, providing data support for subsequent technical improvements.
IV. Breathability improvement technology
1. Micropore structure design
Microporous structure is one of the effective ways to improve the breathability of materials. By introducing micropores, the breathability can be significantly improved without affecting the waterproof performance of the material. Studies have shown that when the diameter of the micropore is between 0.1-1μm, the breathable effect is good. Specific implementation methods include:
- Laser hole drilling: Use high-precision laser equipment to drill holes on the surface of the material to form evenly distributed micropores.
- Chemical etching: Treat the surface of the material by specific chemical reagents to generate microporous structures.
| Technical Type | Pros | Disadvantages |
|---|---|---|
| Laser hole drilling | High accuracy and strong controllability | High equipment cost |
| Chemical etching | Low cost and easy operation | It has certain pollution to the environment |
2. Composite coating technology
Composite coating technology is to enhance its breathability by adding one or more special coatings to the surface of SBR composite fabrics. Commonly used coating materials include polyurethane (PU), polyethylene (PE), etc. This type of coating not only improves breathability, but also imparts better wear resistance and anti-aging properties to the material.
| Coating Material | Breathable performance improvement rate | Abrasion resistance performance improvement rate |
|---|---|---|
| PU | 30% | 20% |
| PE | 25% | 15% |
3.Nanomaterial modification
Nanomaterials have unique physicochemical properties and perform well in improving the breathability of SBR composite fabrics. For example, materials such as nanosilicon dioxide (SiO₂) and nanozinc oxide (ZnO) can significantly improve the breathability of the material while maintaining its original waterproof properties.
| Nanomaterials | Breathable performance improvement rate | Waterproof performance retention rate |
|---|---|---|
| SiO₂ | 40% | 95% |
| ZnO | 35% | 98% |
5. Practical application case analysis
1. Case 1: A brand of diving suit
The brand has improved SBR composite fabrics with laser punching technology, and the results show that its breathable performance has been improved by about 30%. Divers obviously feel more comfortable during long diving, and the feeling of stuffiness is significantly reduced. According to user feedback, this diving suit has a very good reputation in the market and its sales have also increased significantly.
2. Case 2: A professional diving team
The team finally chose the nanomaterial modification solution after trying a variety of breathability improvement technologies. After many actual dive tests, it was found that its breathable performance was improved by nearly 40%, and its waterproof performance was almost unaffected. Team members generally reported that this new diving suit still performs well in extreme environments, greatly improving their work efficiency and safety.
VI. Conclusion and Outlook
Through the study of the improvement of breathability of SBR composite fabrics, this paper proposes a variety of effective solutions, such as micropore structure design, composite coating technology and nanomaterial modification. These technologies not only significantly improve the breathable performance of the material, but also take into account other important performance indicators, such as water resistance and wear resistance. In the future, with the continuous emergence of new materials and new technologies, the breathability of SBR composite fabrics is expected to be further improved, providing divers with better quality protective equipment.
