Fishing net thread

Buyers should prioritize High-Tenacity Nylon (Polyamide) or UHMWPE (Dyneema/Spectra) for professional use. Nylon is preferred for its elasticity and abrasion resistance, while UHMWPE offers a higher strength-to-diameter ratio, allowing for thinner nets that reduce water resistance. Ensure the thread has UV-stabilization treatment to prevent degradation from prolonged sun exposure.

Thread size is typically measured in Denier (D) or Tex. For deep-sea commercial fishing, a multi-filament twisted or braided structure is essential for durability. For gillnets, monofilament or multi-monofilament is better for invisibility. Always verify the Breaking Strength (kg/lb) to ensure it meets the target species' weight requirements.

Request documentation for ISO 1805:2006 (determination of breaking force and knot breaking force of netting yarns). If the nets are used in regulated waters, ensure the materials comply with environmental safety standards to avoid microplastic shedding. Suppliers on Made-in-China.com often provide SGS or Intertek test reports for tensile strength and chemical composition.

The Knot Breaking Force is usually 30-50% lower than the straight-line breaking force. High-quality thread must maintain knot stability to prevent slipping. Look for threads with a bonded finish or resin coating, which enhances knot security and reduces fraying during the net-making process.

The primary risk is material substitution, where lower-grade polyester is mixed with nylon to reduce costs. To mitigate this, request a pre-shipment sample and conduct a burn test or lab analysis. Another risk is weight discrepancy; ensure the contract specifies whether the price is based on net weight (thread only) or gross weight (including the heavy plastic spool).

Focus on volume-based pricing tiers. For orders exceeding 500kg to 1 ton, you can typically negotiate a 5-10% discount. Additionally, ask for customized spool sizes to fit your specific netting machinery, which can reduce your local labor costs for rewinding.

Fishing net thread is sensitive to moisture and extreme heat during transit, which can affect its tensile strength. Ensure the supplier uses moisture-proof PE inner packaging and sturdy outer cartons. For large volumes, FCL (Full Container Load) is recommended to prevent the spools from being crushed by heavier cargo in LCL shipments.
