Production Process

Step 1: Polyester Fiber Selection and Preparation

Step 2: Core Stranding (Inner Braid Preparation)

Step 3: Outer Braid Yarn Preparation

Step 4: Double Braiding (Inner Core + Outer Braid Integration)

Step 5: Post-Braiding Treatment and Finishing

• Heat Setting: The rope is passed through a heat chamber to stabilize the braided structure, reducing residual tension and preventing shrinkage during future use in marine environments.
• Trimming and Deburring: Any loose yarns or frayed edges are trimmed to create a smooth, uniform surface, which minimizes friction and abrasion when the rope is used with sailing hardware (e.g., winches, cleats).
• Quality Testing: Samples of the finished rope are tested for breaking load (using a tensile testing machine), abrasion resistance, and water absorption to ensure they meet marine sailing standards. Ropes that pass testing are wound onto large spools or cut into custom lengths for packaging.

2. Application Scope

Marine Sailing Core Functions

• Mainsheet and Jib Sheet Ropes: Used as mainsheet (controls the mainsail) and jib sheet (controls the jib sail) ropes for sailboats, from small recreational dinghies to mid-sized cruising yachts. The high breaking load withstands the tension generated by strong winds, while the double braided structure ensures smooth handling on winches—critical for adjusting sail position quickly and safely.
• Halyard Ropes: Serves as halyards (ropes used to raise/lower sails, such as the mainsail halyard or genoa halyard). The polyester material resists stretching under the weight of sails, maintaining consistent sail height, and the double braid’s durability stands up to repeated friction with mast hardware.

Vessel Mooring and Docking

• Dock Lines and Mooring Lines: Suitable for dock lines (securing boats to docks during short stops) and mooring lines (long-term anchoring to buoys or piers). The high breaking load handles wind and tide forces, while polyester’s resistance to saltwater and UV rays prevents degradation, ensuring long-term reliability in coastal or offshore mooring.

Recreational and Competitive Sailing

• Regatta and Racing Sailboats: Used in competitive sailing events (e.g., regattas) where performance and strength are critical. The rope’s low stretch (a property of polyester) ensures precise sail control, which can impact race outcomes, and its high breaking load provides safety during high-speed maneuvers in strong winds.
• Recreational Watercraft: Applied to small recreational sailboats (e.g., day sailers) for tasks like securing auxiliary sails, tying down on-deck gear, or creating temporary lines for swimming platforms. Its durability and marine resistance make it suitable for frequent use in lakes, bays, or coastal waters.

Commercial and Utility Marine Use

• Small Commercial Vessels: Used on small commercial boats (e.g., fishing boats, tour boats) for tasks like securing fishing nets, tying off equipment, or as backup lines for mooring. The high breaking load supports the weight of heavy gear, while the double braid’s abrasion resistance withstands contact with fishing hardware or boat hulls.
• Marine Maintenance and Repair: Employed during marine maintenance (e.g., hauling small parts, securing boats during repairs) or as temporary lines for floating structures (e.g., small docks, work platforms). Its strength and durability ensure safety during maintenance tasks, even in wet or salty conditions.
