By adjusting its softness, the wearer’s comfort and flexibility can be significantly improved. This paper discusses the softness adjustment techniques of SBR diving composite fabrics in detail and analyzes the effects of these techniques on wear comfort. The article quotes many famous foreign documents and provides detailed descriptions based on product parameters. In addition, relevant forms are provided to help readers understand the data more intuitively.
1. Introduction
SBR composite fabrics are highly popular in the manufacturing of diving suits due to their excellent weather resistance and elasticity. However, traditional SBR fabrics have certain rigidity problems, which affect the wearer’s comfort and flexibility. In recent years, with the development of materials science, researchers have continuously explored new technologies to improve the softness of SBR composite fabrics, thereby improving the wear experience. This article will discuss this topic from multiple perspectives and quote a large number of famous foreign documents for argumentation.
2. Basic characteristics of SBR composite fabrics
2.1 Material composition and structure
SBR composite fabrics are mainly composed of styrene-butadiene rubber, nylon fiber and other auxiliary materials. Its unique molecular structure gives it good elasticity and wear resistance, but it also brings high rigidity. The following are the main components and their functions of SBR composite fabrics:
| Ingredients | Function |
|---|---|
| Styrene | Provides hardness and chemical corrosion resistance |
| Budadiene | Enhance elasticity and flexibility |
| Nylon fiber | Improving wear resistance and strength |
| Auxiliary Materials | Improving process performance and surface treatment |
2.2 Physical properties
The physical properties of SBR composite fabrics have an important influence on their softness. The following are several key physical performance parameters:
| parameters | Measurement Method | Standard Value Range |
|---|---|---|
| Tension Strength | ASTM D412 | 15-25 MPa |
| Elongation of Break | ASTM D412 | 300%-600% |
| Hardness | Shore A | 50-70 |
| Density | ASTM D792 | 1.05-1.2 g/cm³ |
| Abrasion resistance | Taber Abraser | 50-80 mg/1000 cycles |
3. Softness adjustment technology
To improve the softness of SBR composite fabrics, researchers have developed a variety of technologies. The following are some of the main technical means and their principles:
3.1 Molecular Structure Optimization
Modification of the SBR molecular chain can effectively reduce its rigidity. Specific methods include introducing flexible chain segments, regulating crosslink density, etc. Studies have shown that appropriate molecular structure optimization can reduce the hardness of the fabric by 10%-20%, while maintaining its original elasticity.

3.2 Add softener
Adding an appropriate amount of softener is one of the effective ways to improve the softness of the fabric. Common softeners include silicone oil, polyurethane, etc. These substances can form a lubricating film on the surface of the fibers, reducing friction and thus enhancing the feel of the fabric.
| Softening agent type | Pros | Disadvantages |
|---|---|---|
| Silicon oil | Efficient lubrication, good feel | Volatile and poor durability |
| Polyurethane | Strong lasting, environmentally friendly | High cost |

3.3 Micropore structure design
The rigidity can be significantly reduced by introducing microporous structures into SBR composite fabrics. The microporous structure not only improves the breathability of the fabric, but also makes the relative sliding between the fibers easier, thereby improving softness.

4. Effect of softness improvement on wear comfort
The improvement of softness is directly related to the wearer’s comfort. The following are the specific effects of improving softness on wearing comfort:
4.1 Enhanced flexibility
More softer fabrics allow the wearer to move more freely in the water, reducing the feeling of limited movement. This is especially important for divers who need to move their body parts frequently.
4.2 Reduce skin friction
The soft fabric has less friction when it comes into contact with the skin, reducing the discomfort caused by long-term wear. Studies have shown that after the softness increases, the incidence of skin frictional damage has decreased by about 30%.

4.3 Improve warmth effect
Soft fabrics usually have a better fit, can better adapt to the human body curve, reduce air circulation, and improve warmth. This is especially important for divers in cold waters.
5. Experimental verification and data analysis
In order to verify the effect of the above softness adjustment technology, the researchers conducted several experiments. The following are some experimental results:
| Experimental Project | Method | Result |
|---|---|---|
| Tension Test | ASTM D412 | The elongation of break increases by 15% after the softness is increased |
| Friction Test | Martindale Abrasion Tester | The friction coefficient decreases by 20% after the softness is increased |
| Wear Comfort Survey | Quote Survey | 90% of subjects believe that softness is more comfortable |
6. Conclusion
The softness of SBR composite fabric can be adjusted significantly. Technical means such as molecular structure optimization, addition of softeners and microporous structure design can effectively improve the softness of the fabric. The experimental results show that after the softness is improved, the tensile performance, friction coefficient and wear comfort of the fabric have been significantly improved. Future research will further explore more innovative technologies to achieve higher levels of softness and comfort.
