Problems solved by technology

[0004] The disadvantage of the existing ultra-high molecular weight polyethylene cables is that after the weaving is completed, each strand of the cable itself has a certain torsional stress, which will reduce the overall tensile strength of the cable

Embodiment 1

[0023] Embodiment 1 polyethylene cable

[0024] like figure 1 Shown, a kind of polyethylene cable of the present invention comprises a plurality of strands, wherein a plurality of strands are twisted and woven from high molecular polyethylene fibers, and each The high molecular weight polyethylene fibers are respectively subjected to torsion stress elimination treatment, which can be realized by rotating the polyethylene fiber coil when weaving the rope strands. Specifically, the inner layer rope 1 comprising twelve strands and the outer layer rope 2 comprising twenty-four strands are respectively braided from a plurality of said strands to form a plurality of strands of said inner rope 1 It is twisted and woven from high molecular polyethylene fiber, and the multiple strands that make up the outer layer rope 2 are twisted and woven from polyester fiber, and the inner layer rope and the outer layer rope are bonded with Glue, the glue is configured by epoxy resin, curing agen...

Embodiment 2

[0026] Embodiment 2 A kind of manufacturing process of polyethylene cable

[0027] The manufacturing process of polyethylene cable of the present invention comprises the following steps:

[0028] 1) Immerse the high molecular polyethylene fiber coils prepared to weave the inner layer rope into vegetable oil to form an oil film on the surface of the high molecular polyethylene fiber, specifically, the vegetable oil is a vegetable oil-based lubricant;

[0029] 2) Use cable braiding equipment to twist and weave the fibers on the polymer polyethylene fiber coils into rope strands, and rotate the polymer polyethylene fiber coils in the direction opposite to the fiber twisting and winding direction during the rope strand weaving process, thereby Reduce the torsional stress inside the fiber itself after the strands are braided;

[0030] 3) Use cable braiding equipment to weave the twelve strands obtained in step 2 into an inner layer rope, and immerse the inner layer rope in the glu...

Abstract

The invention discloses a polyethylene mooring rope and a manufacturing process thereof. The mooring rope comprises a plurality of rope strands which are formed with high polymer polyethylene fibers as the material through twisting and weaving. The torsional stress eliminating treatment is conducted on each high polymer polyethylene fiber when the high polymer polyethylene fibers are woven into the rope strands. The polyethylene mooring rope has the advantages that the torsional stress eliminating treatment is conducted when each rope strand is woven, and therefore when the rope is pulled, theeliminated torsional stress can not provide additional shearing force, and the tensile strength of the rope is improved. The manufacturing process of the polyethylene mooring rope provides a specifictorsional stress eliminating method. The polyethylene mooring rope produced through the process has higher tensile strength.

Description

technical field [0001] The invention relates to a polyethylene cable and its manufacturing process. Background technique [0002] At present, ultra-high molecular weight polyethylene (UHMW-PE) is a thermoplastic engineering plastic with a linear structure and excellent comprehensive properties. Using gel extrusion ultra-stretching method, using paraffin as a solvent, to produce ultra-high molecular weight polyethylene fibers. Through ultra-thermal stretching, high-strength, high-modulus fiber filaments are produced, which are produced through special twisting, compounding, and weaving. rope. [0003] Ultra-high molecular weight polyethylene cables are currently the strongest cables in the world. The successful development of the rope has triggered the replacement of traditional steel wire cables in various occasions. It is widely used in ship mooring and civil use in many countries such as the United States, Western Europe, and Japan, and its superior performance has been ...
