When performance matters, the choice is clear
Manufacturers of firefighting gear, industrial workwear, law enforcement and military uniforms face an impossible trade-off: meet stringent safety regulations, while keeping garments lightweight enough for extended wear during demanding physical activity. Conventional flame-retardant materials like FR cotton degrade quickly and are heavier.
Teijinconex® was engineered to solve these challenges. That's why we're trusted by 1,000+ manufacturers worldwide.

How Teijinconex® is used
Teijinconex® is ideal for manufacturing protective wear garments and other industrial applications, each with unique challenges and opportunities.
Military
When tactical operations demand reliability, Teijinconex® delivers exceptional tenacity for uniforms that withstand rigorous field use, lightweight durability that maintains flexibility during demanding physical activity, and dope-dyed colors that preserve camouflage integrity through harsh conditions and repeated laundering.
Firefighting
Firefighting gear must perform when it matters most. Teijinconex® gives garment manufacturers the fiber foundation to build it. With a high Limiting Oxygen Index (LOI), a decomposition temperature above 400 °C, and fibers that will not melt or drip, fabrics containing Teijinconex® meet and exceed EN 469. Our dope-dyed range maintains color consistency through intensive laundering and decontamination, supporting fleet uniformity across the full garment lifecycle.
Law enforcement
When duty demands professional presence and reliable performance, Teijinconex® delivers superior durability that withstands daily wear and frequent laundering, maintains a sharp, professional appearance with dope-dyed colors that resist fading, and offers lightweight comfort for long shifts. Teijinconex® keeps officers looking professional while reducing long-term uniform replacement costs.
Automotive
Engines, heavy machinery, and oil and gas exploration systems are evolving at a rapid pace and the rubber parts used in these applications are subject to increasingly challenging conditions and performance standards.
Integrating Teijinconex® into product development processes can improve a wide variety of elastomer products, maximizing strength, reducing weight, and enhancing heat and chemical resistance.

Product value
What is Teijinconex®?
Teijinconex® is a high-performance meta-aramid fiber, produced in Japan and Thailand. A lightweight synthetic material engineered for superior heat, flame, and chemical resistance. Unlike natural fibers that degrade under thermal stress or other synthetic materials that melt, Teijinconex® maintains its protective properties across extreme temperature ranges and repeated laundering cycles.
Key properties:
- Thermal resistance: >400°C
- Chemical resistance: Excellent against acids, alkalis, solvents
- Does not melt, ignite, or adhere to skin
- OEKO TEX® certified
- Maintains strength after 100+ hours at 230°C
- Compatible with blends (often paired with Twaron® para-aramid)
No PFAS or PFOA added
No fluorine-containing raw materials or compounds, including PFAS, are intentionally added during the production of Teijinconex® fibers. As PFAS regulations tighten across global markets, fabric producers and garment manufacturers can rely on Teijinconex® fibers that comply with current EU legislation and REACH restrictions.

Safer in color with Teijinconex®
Our dope-dyed range covers approximately 90% of Pantone colors. Whether you need standard safety colors or custom brand matching, Teijinconex® delivers.
Dope-dyed fibers maintain vibrant color even after repeated industrial laundering and prolonged UV exposure, far outlasting piece-dyed alternatives. Longer-lasting color means extended garment lifespan and better return on investment.
Solutions
What types of Teijinconex® do we offer?
Teijinconex® neo fiber for customization
Teijinconex® neo is a dyeable meta-aramid staple fiber. Its excellent dyeability means that producers of yarns and fabrics are able to dye their products to various colors according to the customer’s requirement. This also allows more flexible and efficient stock management.
Teijinconex® dope-dyed fiber for color choice
Dope-dyed fibers bring cost savings and a wide range of colors to protective apparel. Unlike conventional methods such as piece dyeing, this technique is more energy-efficient, conserves water, and results in significantly lower carbon emissions. In addition, dope-dyed fibers retain their vibrant color for longer, leading to extended use of garments.
Teijinconex® raw white fiber for multiple applications
Teijinconex® raw white fiber is a staple meta-aramid fiber that has not been treated for color addition. The material’s high-performance mechanical properties can be used in a wide range of applications, from protective clothing to automotive hoses, industrial felt, copy cleaners, speaker dampers and filtration systems.
Teijinconex® tow for strength
The strength of Teijinconex® tow is ideal for conversion into high-tenacity yarn. It is commonly used for producing high-strength sewing threads.
Teijinconex® KB (stretch-broken yarn) for durability
Teijinconex® KB is a stretch-broken yarn that offers outstanding strength and durability. It is typically used by manufacturers for applications that require long-term heat resistance and higher strength, such as automotive hose reinforcement.
Teijinconex® short-cut fiber for heat-resistant reinforcement
Teijinconex® short-cut fiber is composed of finely chopped strands of between 1–6 mm, typically used by manufacturers to reinforce engineering plastics and rubber compounds. Due to its excellent heat resistance, Teijinconex® shortcut fiber does not degrade with the high temperatures required for molding plastics or vulcanizing rubber. These qualities make it ideal for improving the abrasion resistance of rubber or plastic parts.
Knowledge and expertise
