Olive green fibers capable of reducing water resistance of meshes and used for weaving net

Abstract

Olive green fibers capable of reducing water resistance of meshes and used for weaving a net adopt LLDPE (linear low density polyethylene) resin, PP (polypropylene) resin, an olive green pigment, an auxiliary, an antioxidant 1010, a fiber winding machine, a fiber separating machine, a stirring machine, a single-screw extruder and an electrical heating draft machine capable of realizing two times of drafting. The olive green fibers are characterized in that the PP resin, the LLDPE resin, the antioxidant 1010, the olive green pigment and the white oil auxiliary are mixed and stirred by the stirring machine until the materials are stirred uniformly so as to obtain a blended granular material; the blended granular material is subjected to melt extrusion by the aid of the single-screw extruder, spun filaments obtained through melt extrusion are subjected to cooling and pre-drafting through low-temperature water in a cooling water tank and a first drafting roller, pre-drafted filaments are subjected to hot drafting for two times through a high-temperature first drafting water bath and a second drafting roller as well as a high-temperature second drafting hot oil bath and a third drafting roller, the total drafting multiple is controlled in a range from 9.5 to 10.2, and the fiber winding machine adopting a torque motor is used for winding fiber bundles; the fiber bundles are subjected to fiber separation by the aid of the fiber separating machine so as to obtain the olive green fibers capable of reducing water resistance of the meshes and used for weaving the net.

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...

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
