Abstract

A self-reinforced polyethylene wring twist netting used for fishing is provided. The utility model relates to fishing used netting and aims to solve the problem that the strength of the polyethylene wring twist netting is relatively low. The technical scheme of this utility model is to use the net wire twisted by the self-reinforced polyethylene monofilament to weave the netting. The characteristic of the utility model is that the bar of the mesh is twisted by two streams. The two streams of each bar cross by one time with the two streams of the next bar to form the mesh connection point and the string streams of the bar inclined pass through the connection point. This utility model is used for net cage and fishing gear.

Description

A kind of fishing self-reinforcing polyethylene twist net slice

Technical field:

The utility model relates to fishing net sheet.

Background technology

The net sheet is the sheet braided fabric that netting twine is woven into certain mesh structure, and the mesh shape is generally rhombus or hexagon; The net sheet is a main material of forming net cage or fishing gear, and the performance of its structure, shape, specification and tensile mechanical properties and net cage or fishing gear has confidential relation.Make net sheet fibrous material commonly used polyethylene (PE), polyamide fibre (PA) and terylene (PES) are arranged.The line of mesh grid sheet is called netting twine, and two intertubercular line segments in each mesh are called the order pin, and the netting twine of using in the fishery is generally twisted with the fingers by three strands, per sharely comprises several monofilament.The net sheet is divided into knotless netting and knotted netting two classes, and knotless netting comprises twist net slice, raschel netting and inserting; Knotted netting comprises reef knotted netting, English knotted netting and the distortion sheet of knotting.

Twist net slice generally adopts polyethylene monofilament, this net sheet is compared with raschel netting with equal tensile mechanical properties or knotted netting, twist net slice has sinking speed in fish production fast, resistance to water-flow is little, rate of drying is fast, be easy to clean and the advantage of easy operating when receiving hoisting net, in large-scale deep-water netted case resisting wind and wave, use, and have and substitute woven knotted netting, raschel netting is at purse seine, the trend of using on trawlnet and the trap, and be not limited in fish production and use, at golf driving net, the jungle protection network, fly net, safety net, use is also arranged in the other fields such as hammock.But the monofilament that existing fishing is adopted with the polyethylene twist net slice is common polyethylene monofilament, common polyethylene monofilament high-class product fracture strength 56 cN/tex, monofilament knot strength 39cN/tex (SC5005-1988 standard).With high density polyethylene (HDPE) (HDPE) is raw material and the fishing self-reinforcing polyethylene monofilament that adopts the production of self-reinforcing technology, and its fracture strength and knot strength are respectively up to 85cN/tex and 47cN/tex.Common polyethylene monofilament is compared with the self-reinforcing polyethylene monofilament, and the monofilament brute force is low, and corresponding net sheet brute force is also lower.

The utility model content

The utility model need solve the fishing powerful relatively low problem of polyethylene twist net slice.

The technical solution of the utility model adopts the netting twine mesh grid sheet of self-reinforcing polyethylene monofilament twisted, the order pin that it is characterized in that mesh is twisted with the fingers by two strands, two bursts of two stock-traders' know-hows with adjacent order pin of each root order pin once intersect to form the mesh tie point, the oblique tie point that passes through of order payment to a porter thigh.

The utility model is because the employing high density polyethylene (HDPE) is the self-reinforcing fishing polyethylene monofilament of raw material production, and its fracture strength and knot strength are apparently higher than the fishing polyethylene monofilament; Two strands of every order pin with adjacent order pin two strands are only through once intersecting, form diamond mesh, the advantage of diamond mesh is that the net sheet is subjected to the mutual handover of netting twine that the active force of different directions can be by diagonal cross, and follow the corresponding change of mesh shape and make active force obtain buffering, thereby improve the mechanical property of fishing with the polyethylene twist net slice; The order pin netting twine of net sheet adopts the twine twisted, is twisted into net while can twist thread, and structure, flexibility, drainability and the outward appearance of twist net slice all had clear improvement.The result shows through mechanical test, (mesh size is 50mm under the same conditions, monofilament linear density is 36tex, the mesh shape is diamond mesh), 36 strands of net sheets of the utility model brute force is higher than 52 strands of common polyethylene twist net slices, number of share of stock has reduced by 30.8%, its net sheet weight also only is 57.8% of common polyethylene twist net slice weight, the more common polyethylene twist net slice of order pin diameter (2.01mm) (2.50mm) has reduced 0.49mm, it only is 80.4% of common polyethylene twist net slice order pin diameter, reach 2.50mm as self-reinforcing polyethylene twist net slice order pin diameter, its single line ultimate strength can reach 154.7% of 52 strands of common polyethylene twist net slices; The raising of net sheet mechanical property, both guaranteed net cage or fishing gear safe, saved the fish production energy consumption, have favorable economic benefit, social benefit and ecological benefits.

Description of drawings

What accompanying drawing was represented is the structural representation of a kind of fishing with self-reinforcing polyethylene twist net slice.

The specific embodiment

Below in conjunction with the description of drawings specific embodiment of the present utility model:

The utility model adopts the netting twine mesh grid sheet of self-reinforcing polyethylene monofilament twisted, the quantity of stranding 1 usefulness monofilament (or single thread or single twisted netting twine) is pressed the mesh specification of net sheet and is determined, by the net machine their twisteds are become thigh 1, the outer twist that employing and order pin netting twine 4 specifications are complementary with the thigh twisted together, reach after the order pin Len req, two bursts of two stock-traders' know-hows with adjacent order pin of every order pin once intersect to form mesh tie point 3, and line thigh oblique 2 is by the mesh tie point;

For example: making specification is the net sheet of HSPE-36tex * 18 * 2-50mm, order pin diameter 2.01mm, determine that stranding is 18 with monofilament quantity, with order pin netting twine specification be complementary outer twist 170T/m, order pin netting twine sth. made by twisting to for " S " to, number of share of stock is 2 strands, adopt the net machine together with the thigh twisted, reach after the order pin Len req 50mm, the thigh of every order pin forms mesh tie point 1 time with the thigh of adjacent order pin in mesh tie point place intersection, while the oblique mesh tie point by the net sheet of order payment to a porter thigh is stranded the diamond mesh twist net slice of twisting thread.If the line thigh of order pin only intersects once, then strand oblique tie point by the net sheet; If the line thigh of order pin intersects twice or repeatedly, then thigh is " Z " font by tie point, longer at the interconnective netting twine in mesh junction, the variation of mesh shape is bigger, and the mesh shape can become hexagon from rhombus.

Claims

1, a kind of fishing self-reinforcing polyethylene twist net slice, adopt the netting twine mesh grid sheet of self-reinforcing polyethylene monofilament twisted, the order pin that it is characterized in that mesh is twisted with the fingers by two strands, and two bursts of two stock-traders' know-hows with adjacent order pin of each root order pin once intersect to form the mesh tie point, the oblique tie point that passes through of order payment to a porter thigh.

2, a kind of fishing according to claim 1 is characterized in that with self-reinforcing polyethylene twist net slice the stranding monofilament is 18, order payment to a porter diameter 2.01mm, and the sth. made by twisting of order pin netting twine is to being " S " to, bar size 50mm.
