Description

Technical Field

[0001] The invention relates to the technical field of fishing net line processing, and in particular to a processing device and method for high-strength fishing net lines. Background Art

[0002] Fishing net line refers to the line with a diameter of less than 4 mm for weaving mesh and sewing net fishing gear, which is the main material for making fishing nets. The physical and chemical properties of the fishing net line can be divided into two categories according to the materials used to make the fishing net line: plant fiber fishing net line and synthetic fiber fishing net line. The thickness of the fishing net line. It is the main indicator of the fishing net line. The thickness of the fishing net line.

[0003] Twisted yarn refers to a yarn made by twisting 2, 3 or 4 strands of yarn. And there are single twist yarn, double twist yarn and composite twist yarn. For example, single yarn in single twist yarn, single twist yarn in double twist yarn, double twist yarn in composite twist yarn, etc. Its single twist yarn is also called single yarn. If several single yarns or filaments are combined together and twisted once, it will be a product. Therefore, it is very easy to untwist and is rarely used in fisheries. And double twist yarn is also called double yarn, which is mainly a product made by twisting several single yarns or filaments together into strands, and then twisting several strands (usually 3) in the opposite twist direction. Therefore, synthetic fiber mesh lines mostly adopt this structure, so it is the main line for various fishing gear. Its composite twist yarn is a product made by twisting several (3 or 4) double twist yarns in the opposite direction.

[0004] Fishing net lines are damaged in actual use mostly because of insufficient strength. In addition, fishing net lines are prone to aging during long-term use. For this reason, we propose a processing equipment and method for high-strength fishing net lines. Summary of the invention
