Nylon Monofilament 

Nylon monofilament (PA monofilament) is a single continuous filament produced by melt spinning of polyamide. Different from nylon multifilament, it has a diameter of 0.1–2 mm, featuring high strength, excellent wear resistance and good resilience. It is widely used for industrial filtration, brush bristles, ropes and fishing nets.

Classification

• By material PA6: Cost-effective with good toughness and resilience. Suitable for standard filter meshes, industrial brush bristles, common ropes and fishing nets. PA66: Superior in strength and heat resistance for high-temperature and heavy-duty conditions. Applied for high-end filter media, heavy-duty brush bristles and safety webbing.

• By diameter Coarse monofilament (≥1.0 mm): High tensile strength for ropes, safety cables and heavy fishing lines. Fine monofilament (0.1–1.0 mm): Most versatile for woven screens, filter cloths and industrial brush bristles. Micro monofilament (＜0.1 mm): For high-precision fine filtration fabrics.

Properties

It stands out for outstanding wear resistance (about 10 times that of cotton and 20 times that of wool). It recovers well after stretching and resists permanent deformation. PA6 melts at 215–220℃ while PA66 at around 260℃, with a density of 1.14 g/cm³ and light weight. It has good resistance to alkali and reducing agents, but poor resistance to concentrated acid. UV resistance is limited; anti-aging modification is recommended for outdoor applications.

Industrial Applications

✅ Filtration & screening: Industrial filter meshes, screens and filter cloths for solid-liquid separation in wastewater, chemical, food and mining industries, easy to clean and less prone to clogging. 

✅ Industrial brush bristles: Cleaning roller brushes and impurity-removing brushes, wear-resistant and not easy to bend or shed filaments. 

✅ Ropes & safety products: Pulling ropes, safety slings and heavy-duty cables. 

✅ Fishery: Aquaculture nets, fishing nets and fishing lines, resistant to seawater corrosion.
