270gsm Modacrylic Cotton IFR Inherently Flame Retardant Fabric is a high-performance textile engineered for industrial safety and comfort. Here's a detailed breakdown based on technical specifications, certifications, and real-world applications:

1.Composition & Structure
This IFR fabric typically blends 60% modacrylic, 38% cotton, and 2% antistatic fibers (e.g., carbon fibers) in a 2/1 twill weave . The modacrylic component provides inherent flame resistance without chemical treatments, while cotton enhances breathability and softness. The antistatic fibers prevent electrostatic discharge, critical for environments with flammable materials . Some variants include spandex for stretchability (e.g., 60% modacrylic, 38% cotton, 2% spandex) .

2. Key Properties 
Flame Resistance: Self-extinguishing and non-dripping, meeting EN 11611 (welding protection) and EN 11612 (heat/flame resistance) standards. The modacrylic structure forms a protective carbon layer when exposed to fire, blocking heat transfer .  
Antistatic: Complies with EN 1149 (electrostatic properties) and EN 13688 (general workwear), making it suitable for industries like oil/gas and electrical maintenance .  Durability: Resistant to tearing, abrasion, and metal splashes. A special production process ensures colorfastness and dimensional stability after washing .  
Comfort: Cotton content ensures breathability and moisture absorption, while the fabric remains soft even after prolonged use .  

3. Certifications
European Standards: EN 11611 (welding), EN 11612 (heat/flame), EN 1149 (antistatic), EN 20471 (high visibility), and EN 13688 (workwear) .  
Eco-Friendly: OEKO-TEX® Standard 100 certified, ensuring no harmful chemicals .  
Other Compliance: NFPA 70E (electrical arc), NFPA 2112 (flame resistance)

4. Applications
Protective Clothing: Ideal for welders, firefighters, and workers in petrochemical or electrical industries. It withstands sparks, molten metal, and radiant heat .  
High-Visibility Gear: Available in fluorescent yellow/orange (e.g., EN 20471-compliant variants) for construction or emergency services .  

Industrial Workwear: Used in coveralls, jackets, and uniforms requiring multi-hazard protection (flame, static, and abrasion) .  

5. Performance in Use
Wash Resistance: Retains FR properties after 100+ washes (per EN 531 standards), with minimal shrinkage or color fading .  
Thermal Protection: Provides thermal stability up to high temperatures, tested against EN 533 (radiant heat) and EN 531 (convective heat) .  
Weight & Feel: The 270gsm weight offers a balance between warmth and breathability, suitable for year-round use in moderate to cold environments .  

6. Sustainability
Inherent FR: Unlike treated fabrics, its flame resistance doesn’t rely on chemical coatings, reducing environmental impact .  
Recyclability: Modacrylic fibers can be recycled in specialized facilities, aligning with circular economy goals .  

The 270gsm Modacrylic Cotton IFR Fabric is a versatile, durable, and certified solution for demanding industrial environments. Its blend of inherent flame resistance, antistatic properties, and cotton comfort makes it a top choice for protective workwear.
