FR Aramid steel wire sewing thread

Key Characteristics

Dual-core composite structure: Combines meta/para-aramid filament with high-strength steel wire core, integrating aramid’s flame retardancy and steel wire’s tensile toughness.

Inherent fire safety performance: Permanently flame-retardant, self-extinguishing away from fire, no melting or dripping; the steel wire core remains stable under high temperature without deformation.

Ultra-high tensile strength: Outperforms pure aramid sewing thread, withstanding heavy load and strong pulling force during stitching and use.

Excellent environmental adaptability: Resists acids, alkalis, organic solvents, UV radiation and abrasion; suitable for harsh industrial, outdoor and high-temperature working scenarios.

Thermal stability: Can work continuously at 260℃; the steel wire core enhances structural rigidity, preventing thread breakage during high-speed machine sewing.

Versatile processability: Compatible with industrial sewing machines and heavy-duty stitching equipment; customizable wire diameter and aramid ply count to match different fabric thicknesses.

Applications

Stitching and reinforcement of heavy-duty flame-retardant protective gear: high-temperature furnace maintenance suits, fire rescue heavy clothing, welding spark-resistant overalls.

Sewing of industrial high-strength fireproof fabrics: fire-resistant conveyor belt edges, high-temperature filter bag seams, furnace lining insulation material stitching.

Reinforcement of tactical equipment: military flame-retardant backpacks, armored vehicle seat covers, field operations gear with load-bearing requirements.

Sewing of special fireproof products: fire escape blanket fixing edges, high-temperature pipeline insulation layer binding, aerospace ground support equipment fabric stitching.
