Para-Aramid (PPTA, Kevlar-type fiber)

• Para aramid fabric is known for high strength and modulus.
• Excellent heat resistance (continuous use at ~200 ℃).
• Outstanding cut and impact resistance; widely used in protective textiles.
• Flame retardant (LOI ~29–30) and excellent chemical stability.

PBO (Poly(p-phenylene benzobisoxazole), Zylon-type fiber)

• PBO fabric is an ultra-high-performance “super fiber” with tensile strength and modulus significantly higher than aramid.
• Thermal decomposition temperature > 600 ℃; exceptional abrasion and cut resistance.
• Superior energy absorption under impact and outstanding flame retardancy (LOI ~68).

Blending Advantages (60% PPTA + 40% PBO)

• Balances cost-effectiveness of para aramid fabric with the extreme performance of PBO fabric.
• Improved flame resistance, thermal stability, cut resistance, and abrasion performance versus pure aramid.
• More affordable and versatile than pure PBO fabric for sale — attractive in the cut resistant fabrics market.

Manufacturing Process

Fiber Preparation

High-performance para-aramid and PBO fibers (filament or staple) are opened, blended and evenly mixed to maintain consistent distribution across the yarn.

Spinning

Use ring spinning or air-jet spinning while holding the 60:40 ratio to produce yarns with uniform strength and durability suitable for cut resistant fabric applications.

Weaving / Knitting

Typical structures include plain, twill, or satin. High-density plain or twill weaves are preferred for superior abrasion and cut-resistance. The fabric can be woven or knitted depending on the final use case.

Finishing

• Heat-setting for dimensional stability.
• In many cases, additional flame-retardant finishing is not required due to inherent FR properties.
• Optional surface coatings (PTFE, silicone, PU) provide water resistance, chemical protection, or extended durability for harsh environments.

Technical Parameters (Typical Values)

• Fabric Weight (GSM): 160–350 g/m² (customizable)
• Tensile Strength: ≥ 2.5 GPa (depends on yarn and weave)
• Modulus: 80–120 GPa
• Thermal Resistance: Continuous use 250–300 ℃; Peak exposure ≥ 500 ℃
• Flame Retardancy: LOI ≥ 35 (higher than pure aramid)
• Abrasion Resistance: 20–30% better than pure para-aramid fabric
• Dimensional Stability: Heat shrinkage ≤ 2% (at 250 ℃)
• Cut Resistance Level: ANSI/ISEA 105 A6–A9 (structure dependent) — a top-tier cut resistant fabric for sale candidate
