Description

High-performance flexible double-braided mesh

Technical Field

The utility model relates to a weave technical field, especially relate to a flexible two braids of high performance are woven and are netted piece.

Background

A sheet-like woven fabric in which mesh wires are woven into a mesh structure of a certain size is called a mesh sheet. Mesh wires generally include both twisted and braided wires. The braided wires are divided into single braided wires and double braided wires. Braided wire includes crust and sinle silk two parts, at present, generally adopts no sinle silk braided wire more in the fishery. In fishery, the braided wire with no core is called as the coreless single braided wire; the braided wire with the wire core and the wire core not being the braided wire is called the braided wire with the core; the braided wire with the wire core being braided wire is called double-braided wire. In fishery, the double-braided wire is rarely applied at present. Compared with twisted yarn, the braided yarn has the obvious advantages of high fiber strength utilization rate and the like, and only the fishing polyethylene braided yarn is taken as an example, the annual output of the braided yarn reaches hundreds of tons in China at present. In fishery, the meshes processed by the above-mentioned coreless single-braided wire, cored single-braided wire, and double-braided wire are referred to as coreless single-braided wire mesh, cored single-braided wire mesh, and double-braided wire mesh, respectively.

The synthetic fiber material suitable for making fishing net sheet includes polyamide fiber, polyethylene monofilament, polypropylene fiber, polyester fiber, etc. The net sheets can be classified into knotted net sheets and knotless net sheets according to the existence of the knots of the fishing net sheets. The net sheet formed by the net threads passing through the knot is called a knotted net sheet. The netting sheet is characterized by convenient processing, manufacturing and repairing after damage, and is a net material which is most widely applied in fishery. The knotted meshes can be divided into slipknot meshes, dead knot meshes and deformed knot meshes according to the types of the net knots. The knotted net sheet can be manually braided or can be braided by a machine. The single-dead-knot type polyethylene woven mesh is low in price, compact in structure and stable in mesh size, is a fishing material which is used in large quantity in the aquatic product industry of China, and has high annual yield. The single-dead-knot polyethylene woven mesh has the good fishing performance, and is widely applied to fishing gear such as trawlnets, net-stretching and crab pots, and also widely applied to aquaculture net cages. Compared with other woven mesh materials, the single-dead-knot type polyethylene woven mesh also has certain price advantage, which further promotes the application of the single-dead-knot type polyethylene woven mesh, so that the single-dead-knot type polyethylene woven mesh is the most common fishing mesh material applied at home and abroad at present, particularly in domestic fishery production. The monofilament adopted in the production of the existing single-knot polyethylene woven mesh for fishing mainly takes common polyethylene monofilament, and the mesh wire for mesh weaving adopts twisted wire; the strength of the common polyethylene monofilament and the polyethylene twisted yarn is lower, and the strength of the woven net sheet of the single-dead-knot type polyethylene woven by the common polyethylene monofilament and the polyethylene twisted yarn is also lower.
