Electromagnetic radiation is categorized into high-frequency and low-frequency types, each requiring different protective measures. For high-frequency protection, there are three main fabric types available.
1. Blended woven anti-electromagnetic radiation fabric closely resembles regular fabric in appearance. It combines nano-metal shielding fibers with other materials, offering a soft, smooth texture. This fabric has been tested to provide 99.9% shielding (over 30dB) while maintaining breathability, washability, and durability. It's ideal for maternity wear, workwear, and everyday clothing.
Available in various weights:
- Cotton thin fabric: 17% shielding fiber, 83% cotton
- Medium/thick fabric: 20% shielding fiber, 28% cotton, 52% polyester
- Thick fabric: 30% shielding fiber, 25% cotton, 45% polyester
2. Blended knit fabric with 32s yarn and 20% shielding fiber, offering good flexibility and comfort for daily use.
3. Nano-ion shielding fabric provides an impressive 99.999999% shielding (70dB+), making it suitable for high-risk environments like telecom rooms, base stations, and radar facilities. It can be used as a lining in clothing and requires only gentle wiping for maintenance.
Key Features:
• Effective electromagnetic radiation shielding from 30MHz to 16GHz, blocking over 99.9% of harmful waves.
• Provides far-infrared health benefits, reduces static, and has antibacterial properties that promote blood circulation and metabolic activity.
Testing Methods:
• Conductivity test using a multimeter confirms its ability to conduct electricity, unlike ordinary fabrics.
• When burned, blended fabric leaves a mesh-like residue, while nano-ion fabric produces metal powder.
• Using a hand-held radiation tester, the red light turns green when the fabric blocks the radiation, confirming its effectiveness.
Applications:
These fabrics are widely used in making clothing for pregnant women, office workers, children, and the elderly. They are also essential in industries such as electronics, telecommunications, power plants, and military sectors where electromagnetic interference needs to be minimized.
Conversion Chart:
3dB → 50%, 6dB → 75%, 9dB → 87.5%, 12dB → 93.75%, 30dB → 99.9%, 70dB → 99.9999%
Understanding Electromagnetic Pollution:
Electromagnetic pollution comes from both natural and artificial sources. Since the mid-20th century, microwave exposure has increased significantly, and many household appliances emit radiation above safe levels. Even common devices like computers, phones, and microwaves contribute to this invisible threat.
Harm to Human Health:
Prolonged exposure to electromagnetic waves can affect multiple systems, including the nervous, immune, circulatory, and reproductive systems. Studies show increased risks of cancer, infertility, and genetic damage. Research from the World Health Organization and other institutions highlights the dangers, especially for children living near high-voltage lines or people working in high-radiation environments.
How Electromagnetic Radiation Affects the Body:
• Thermal effect: Causes internal heating, disrupting organ function.
• Non-thermal effect: Disrupts the body’s natural magnetic balance, causing cellular damage.
• Cumulative effect: Prolonged exposure leads to long-term, irreversible damage.
Protective Solutions:
Anti-radiation fabrics, curtains, and materials are designed to block harmful radiation. These include conductive threads, shielding yarns, and specialized textiles for personal and industrial use. Whether for undergarments, workwear, or home protection, these products help reduce exposure and safeguard health in today’s tech-driven world.
