Common Denier Ranges and Applications
Common Denier Ranges and Applications
Fine Denier (40D – 300D / 44–300 dtex): Used for lightweight, high-performance applications including special technical apparel, sportswear, workwear, and linings.
Medium Denier (400D – 900D / 470–940 dtex): Commonly used for sewing threads, narrow fabrics, and smaller ropes.
Coarse Denier (1000D – 2500D+ / 1200–2800 dtex): Used in heavy-duty industrial applications requiring extreme durability.
Detailed Application List by Denier (Approximate)
210D/212 dtex (PA66): Fishing nets, fishing net threads, specialized sewing thread.
420D/470 dtex (PA66): Industrial sewing thread, technical fabrics, conveyor belts, moderate load-bearing nets.
630D/700 dtex (PA66): Technical apparel, airbags, safety ropes, industrial hoses.
840D/940 dtex (PA66): Standard for airbag fabrics, parachute cords, rubber reinforcement, tire cord, high-strength ropes.
1260D – 1890D / 1400–2100 dtex (PA66): Heavy-duty conveyor belts, timing belts, heavy-duty tarpaulins, large-scale lifting gear, and tire reinforcement fabrics.
2520D / 2800 dtex (PA66): Heavy-duty mooring ropes, industrial nets, high-pressure hoses.
Key Application Industries Automotive:
Airbags, tire reinforcement (tire cord), seat belts, interior fabrics.
Technical Textiles: Conveyor belts, high-pressure hoses, curing tapes, timing belts.
Outdoor & Safety: Parachutes, heavy-duty ropes, nets, tents, tents, sleeping bags.
Industrial Sewing: Heavy-duty threads for technical fabrics.
Key Technical Properties
High Tenacity: Typically (grams per denier) High Melting Point: ~250–260°C, providing better thermal stability than PA6.
Excellent Abrasion Resistance: Critical for safety belts and industrial conveyors.
Low Shrinkage: High-performance variants are designed for heat resistance in tires and airbags.
