The process and principle of anti-infrared fabric
Anti-infrared fabrics are mainly achieved by adding special infrared reflective materials to the fabric or using special coatings. These materials or coatings can reflect infrared rays, making objects difficult to be detected by infrared detectors, thereby achieving the effect of stealth.
A common process is to add infrared reflective fibers to fabrics, these fibers are usually made of polyimide, polyamide, polypropylene and other materials. The surface of these fibers will be covered with a layer of infrared reflective materials, such as titanium dioxide, aluminum oxide, etc., which can reflect infrared rays back, thereby achieving the effect of stealth.
Another common process is to cover the surface of the fabric with a special coating, which is usually made of polyurethane, polyester and other materials. This coating can reflect most of the infrared rays, so as to achieve the effect of stealth. In addition, this coating can also improve the performance of the fabric such as abrasion resistance and water resistance.
In short, the process of anti-infrared fabrics is mainly realized by adding infrared reflective materials or using special coatings, so as to achieve the effect of stealth.
Reflection band of anti-infrared fabric
The reflection band of anti-infrared fabrics is usually in the range of 8-14 microns of infrared rays. This range is also called "thermal infrared band", because the thermal radiation of objects in this range is the strongest, and it is also one of the main detection bands of infrared detectors.
In order to achieve the effect of anti-infrared, anti-infrared fabrics need to reflect or absorb radiation in the thermal infrared band. Generally speaking, the higher the reflectivity of the anti-infrared fabric, the better its stealth effect. Some anti-infrared fabrics also have strong absorption properties, which can absorb radiation in the thermal infrared band and reduce the leakage of thermal signals, thereby enhancing the stealth effect.
It should be noted that the reflection bands of different anti-infrared fabrics may be different, depending on factors such as the type and proportion of infrared reflective materials used in the fabric. Generally speaking, manufacturers of anti-infrared fabrics will choose the most suitable infrared reflective material and proportion according to customer needs and specific application scenarios, so as to achieve the best anti-infrared effect.
Practical application of anti-infrared fabric technology
Anti-infrared fabric technology is widely used in the military field in practical applications, such as military camouflage uniforms, equipment and equipment, etc., to achieve the effect of concealment and protection. In addition, anti-infrared fabrics can also be used in other fields, such as public security, anti-terrorism and other fields.
In the military field, anti-infrared fabrics can effectively reduce the possibility of being discovered by enemy infrared detectors, and improve the survivability and combat efficiency of soldiers. For example, when fighting in the field, wearing anti-infrared camouflage uniforms can greatly reduce the detection range of enemy infrared detectors, making soldiers more concealed and reducing the possibility of being discovered.
In the field of public safety, anti-infrared fabrics can be used to make protective clothing, protective masks, etc., to improve the safety and concealment of law enforcement personnel such as police and special police when performing tasks.
In the field of anti-terrorism, anti-infrared fabrics can be used to make body armor, explosion-proof clothing, etc., to improve the protection capabilities and combat efficiency of special police and soldiers.
In short, the anti-infrared fabric technology is of great significance in practical applications, which can improve the survivability and combat efficiency of personnel, and ensure the safety of the country and the people.
What parameters need to be provided for the production of anti-infrared fabrics?
1. Requirements for reflectivity: The main function of anti-infrared fabrics is to reflect infrared rays, so it is necessary to determine the requirements for reflectivity. The higher the reflectivity, the better the stealth effect. Generally speaking, the reflectivity needs to reach more than 90% in the infrared 8-14 micron band to effectively prevent infrared detection.
2. Types of infrared detectors: Different types of infrared detectors have different requirements for anti-infrared fabrics. For example, some detectors have higher detection sensitivity in the 8-14 micron band, while some detectors have higher detection sensitivity in other bands. Therefore, it is necessary to select the corresponding anti-infrared fabric according to the type of detector used.
3. Application scenarios of fabrics: Different application scenarios have different requirements for anti-infrared fabrics. For example, military camouflage uniforms need to be able to conceal the infrared signals of soldiers, while body armor needs to have multiple functions such as bulletproof, stabproof and infrared proof. Therefore, it is necessary to select the corresponding materials and processes according to the application scenarios of the fabrics.
4. The basic material of the fabric: the basic material of the anti-infrared fabric can be a variety of fiber materials, such as polyester, nylon, polyester, etc. Different fiber materials have different effects on reflectivity and absorptivity, so it is necessary to choose the most suitable material according to customer requirements and application scenarios.
5. The color and pattern of the fabric: Anti-infrared fabrics usually need to be matched with specific camouflage patterns to achieve better concealment. Therefore, it is necessary to design the color and pattern of the fabric according to the customer's requirements and application scenarios.
