Nylon 66 High Tenacity Filament Yarn 840D/140F

Product Introduction

1. Core Definition
This product is a high-tenacity industrial filament yarn made from Nylon 66 (polyhexamethylene adipamide). Nylon 66 offers superior heat resistance, strength, and dimensional stability compared to Nylon 6, making it an ideal choice for high-end industrial applications.

2. Key Specification Breakdown

Nylon 66: Core material with a high melting point (~260°C), excellent heat resistance, anti-creep properties, and chemical resistance, with particularly stable performance under prolonged load.

High Tenacity: Through specialized polymer formulation and spinning processes, the yarn achieves extremely high breaking tenacity and toughness, typically reaching 8.5-9.5 g/d, far exceeding conventional nylon yarns.

840D/140F: Core Technical Parameters

• 840D: Indicates a filament fineness of 840 Denier, a heavy-denier industrial specification that provides high load-bearing capacity and abrasion resistance, suitable for heavy-duty scenarios.

• 140F: Indicates that each single yarn comprises 140 filaments, balancing high strength with a degree of flexibility and coverage.

BR (Bright): No delusterant is added, giving the yarn high luster and a smoother surface, which benefits processing smoothness.

3. Key Features Summary

• Ultra-high strength & toughness: Suitable for high-load, high-impact scenarios.

• Excellent heat resistance: Maintains stable performance in elevated temperature environments.

• Superior abrasion & fatigue resistance: Resistant to breakage or deformation under long-term use.

• Good chemical stability: Offers certain resistance to oils and solvents.

• Smooth surface: Reduces equipment wear and improves processing efficiency.
