It is usually difficult to combine flame retardancy with comfort, yet this fabric manages to do both. Modified acrylic provides the fire resistance - a property inherent to the fiber itself rather than an applied coating, so it won't wash out. Cotton ensures breathability and prevents overheating, keeping workers comfortable even during a full day of wear. The double-knit structure gives the fabric a crisp, substantial feel that resists deformation and curling, allowing the garment to retain its shape after repeated washings. Although designed for industrial safety applications, the fabric lacks the stiffness and coarseness typical of traditional protective materials.

Breathable and Cool

The cotton content ensures airflow, preventing the stifling sensation often associated with thick, non-breathable flame-retardant fabrics during prolonged wear.

Self-Extinguishing

Upon contact with a flame source, the modacrylic fibers soften and contract without melting or dripping. A protective char layer forms on the surface to block heat. Crucially, the fabric self-extinguishes once the ignition source is removed; it does not continue to burn, nor does it emit black smoke or toxic gases.

Durable and Rugged

The double-knit structure offers superior tear and deformation resistance compared to standard single-knit fabrics. It maintains its shape without becoming baggy after just a few wears and withstands industrial laundering.

Permanent Flame Retardancy

Because the flame-retardant properties are inherent to the fiber rather than added via post-treatment, they do not diminish with washing. There is no need to worry about the protective qualities failing after a few months of use.

We can tailor the following specifications to your needs:

If you have specific requirements, simply let us know the intended use, and we will formulate the product accordingly.

Industrial Safety Workwear

Tops, trousers, and coveralls for high-temperature environments such as factories, refineries, and chemical plants.

Emergency & Rescue Gear

Uniforms and equipment requiring fire protection for firefighters, emergency responders, and military or law enforcement personnel.

Automotive & Transportation

Flame-retardant and abrasion-resistant fabrics for seating and interiors in heavy machinery, buses, trains, and other vehicles.

Specialized Protective Gear

Custom solutions for niche applications requiring flame retardancy where off-the-shelf fabrics do not meet specific needs.

Washing: Machine wash on a gentle cycle at temperatures below 40°C.
Bleaching: Do not bleach / Do not use chlorine-based detergents.
Drying: Hang to dry; do not tumble dry.
Ironing: Low-temperature ironing (soleplate max. 110°C); do not use steam.
Professional Maintenance: Gentle dry cleaning permitted.
Special Note: Inherently flame-retardant; flame-retardant properties are permanent.

Q: Do ordinary acrylic fabrics catch fire easily?

Yes, and they burn rapidly. Ordinary acrylic has a Limiting Oxygen Index (LOI) of only 17–20, which is lower than the 21% oxygen concentration in the air. It ignites instantly, melts and drips while burning, and releases toxic gases such as cyanide. It is absolutely unsuitable for use in protective clothing.

Q: Can ordinary acrylic be made flame-retardant through post-treatment?

Ordinary acrylic can be rendered flame-retardant through "FR (Flame Retardant) Treatment." This process typically involves applying chemical flame retardants or coatings to the fabric. However, a drawback is that the flame-retardant properties may diminish with washing, unless specific wash-durable treatment technologies are used.

Q: Why is modified acrylic flame-retardant?

It is modified during the polymerization stage by incorporating chlorine- or phosphorus-based flame-retardant components. This flame-retardant property is inherent to the fiber's molecular structure, not just an external coating. When exposed to fire, it releases combustion-inhibiting substances and simultaneously forms a char layer, causing the flame to extinguish immediately once the heat source is removed.

Q: Is modified acrylic significantly more expensive than standard acrylic?

Yes, it is considerably more expensive due to higher raw material costs and a more complex manufacturing process. However, you are purchasing permanent safety assurance-not a feature that wears off after a few washes. For applications where fire protection is essential, this investment is well worth it. Plus, it is still far less expensive than aramid fibers.

Q: How can I verify that the fabric meets the required standards during procurement?

You must review the documentation provided by the supplier. Specifically, look for the following:
LOI (Limiting Oxygen Index) test report
Washing durability test report (to confirm that flame-retardant performance does not degrade with washing)
Certifications for relevant standards, such as NFPA 2112 or ASTM F1506
Clear indication of whether the material is inherently flame-retardant (modified acrylic) or merely treated for flame retardancy (FR treatment), as their long-term performance differs significantly.
We provide a complete technical data sheet, test reports, and certification documents with every shipment to facilitate your compliance reviews and traceability.
