Olive green fiber for weaving nets to reduce water resistance of nets

Abstract

Olive green fiber for net weaving to reduce the water resistance of the mesh, using LLDPE resin, PP resin, olive green pigment, auxiliary agent, antioxidant 1010, wire collecting machine, wire dividing machine, mixer, single screw extruder and two drafts Electric heating drawing machine, characterized by mixing PP resin, LLDPE resin, antioxidant 1010, olive green pigment, and white oil additives, stirring with a mixer until the materials are evenly stirred to obtain blended pellets; the blended pellets are passed through a single screw The extruder is melted and extruded, and the melted and extruded as-spun yarn is cooled and pre-drawn by the low-temperature water in the cooling water tank and the first drafting roller, and the pre-drawn yarn is passed through the high-temperature first drafting water bath and the second drafting roller, The high-temperature second drafting hot oil bath and the third drafting roller carry out two hot drafts, and the total drafting ratio is controlled at 9.5 times to 10.2 times, and the fiber tow is rewound by a torque motor winding machine; The machine-separated yarn is olive green fiber for weaving nets that can reduce the water resistance of the mesh.

Description

technical field [0001] The invention relates to olive green fiber for weaving nets in offshore breeding industry and ocean fishery. Background technique [0002] In the field of offshore aquaculture and pelagic fishery technology, people have always been very concerned about how to reduce the water resistance of the mesh. In the prior art, people have reduced the water resistance of the offshore aquaculture industry (including offshore cages) by innovating the mesh structure and mesh equipment technology. Aquaculture, offshore seine aquaculture, offshore scallop cage aquaculture, etc.) and pelagic fishery use mesh water resistance. With the development of modern offshore aquaculture and pelagic fisheries towards large-scale, offshore and low-carbonization, this technical field puts forward higher requirements for reducing the water resistance of the mesh, improving the physical and mechanical properties of the mesh and anti-wind and wave performance, People urgently need to...

AI Technical Summary

Problems solved by technology

In the field of prior art, the fibers for weaving nets are made of a single high-density polyethylene resin as raw material, hot water is used as the filament drawing heating medium, and the traditional melt spinning process is used for processing and production, which makes the physical and mechanical properties of the output fibers poor. This further leads to the poor wind and wave resistance of mesh products made of silk, and the large water resistance of the mesh used for offshore farming nets and ocean fishing gear. Under severe sea conditions, it is more likely to cause mesh damage due to high water resistance. , the adaptability of the fibers used for weaving nets in the existing technical field needs to be improved, and it is difficult to adapt to the sustainable development of modern offshore aquaculture and pelagic fisheries

Based on the demand for reducing the water resistance of the mesh in the existing field, people urgently need a new type of olive green fiber material for weaving the mesh that can reduce the water resistance of the mesh, but there is no linear low density polyethylene resin (hereinafter referred to as LLDPE) in the prior art. Resin), polypropylene resin (hereinafter referred to as PP resin), etc. are used as raw materials and special spinning technology to prepare olive green fiber for weaving nets that can reduce the water resistance of the mesh. Solve the long-standing unresolved technical problems that have become people in this technical field
