Abstract

A high strength fishing polythene braided wire relates to a fishing polythene braided wire, which needs to provide a braiding structure for a high strength fishing polythene braided wire. The technical proposal of the utility model is that: the braided wire consists of high strength fishing polythene monofilaments, wire strands and a wire core which are braided together. The utility model is characterized in that: each wire strand consists of 2-6 high strength fishing polythene monofilaments, and 16 wire strands match in pair; when braiding, the wire strands are interlaced and braided into flower nodes with 2 strands pressing on 2 strands, the length of lay between mesh wires is 20mm-40mm, and the wire core of the braided wire uses 30-40 monofilaments. The utility model is applicable to the fishing polythene braided wire.

Description

A kind of high-strength fishing woven polyethylene line

Technical field:

The utility model relates to fishing woven polyethylene line.

Background technology

Just can be directly used in the braiding fishing net, roll rete cord or seam bundle net cage without further processing in the prior art, and the line that is suitable for making fishing gear or net cage casing etting is referred to as netting twine, claim fishing lines again.Netting twine fish for fishery engineering on use very extensively, its production equipment has bell jar and flyer spindle formula twisting machine, braiding machine, ring ingot twisting mill and two-for-one twister.Adapt to various needs, the distribution of the kind of the used fibrous material of netting twine, preparation method and blended fiber all can be different, and this makes the kind of netting twine, classification various.By the kind of the fibrous material of making netting twine, netting twine can be divided into polyethylene (PE) line, polyamide (PA) line, polypropylene (PP) line and polyester (PES) line etc.; Can be divided into monofilament, twist thread and braided wire three classes by the structural shape netting twine.In fishery, the fisherman in country variant area or raiser select monofilament for use, twist thread or weaving thread by preference, custom.By the paired or single bifilar cooperation of some even lines thighs (as 6,8,12,16), the interspersed netting twine that forms that weaves that intersects mutually is called weaving thread; At the central part of weaving thread, dispose some monofilament (yarn), (line) thigh and be the core that is generically and collectively referred to as weaving thread of filler.Because weaving thread is to be intersected mutually to intert by thigh to work out, and must not twist, so the brute force of weaving thread is than the height of twisting thread with rugosity; And have good structural stability, can not produce torsional deflection in the use; The diameter of weaving thread is twisted thread little than identical monofilament number; The pliability of weaving thread is better than twists thread, and it is also more firm to break into anastomose; The identical monofilament number of mass ratio is twisted thread little in the air.The knotted netting that processes with weaving thread increases year by year both at home and abroad, simultaneously, the thick weaving thread of producing is usually used in the seam of all kinds of fishing gears or net cage rete cord and pricks, therefore, weaving thread is to use comparatively general fishing material in especially domestic large-scale middle layer trawl fishery both at home and abroad, all kinds of fishing gear or the net cage production at present.Use in the woven polyethylene line processing enterprise in the existing fishing of China, it is comparatively single based on common polythene monofilament, braided structure to make the used monofilament of line; And polyethylene monofilament mainly is to adopt high density polyethylene (HDPE) (HDPE) raw material to produce through melt spinning and hot draft process as the basic structural unit of fishing with the woven polyethylene line at present, and its fracture strength is 4cN/dtex～6cN/dtex.Common polythene monofilament brute force is low, and the brute force of its weaving thread is also relatively low.

The utility model content

The utility model provides a kind of braided structure for improving woven polyethylene line mechanical property.

The technical solution of the utility model is made of with polyethylene monofilament, line thigh, core braiding high-strength fishing, it is characterized in that every line thigh has 2～6 of polyethylene monofilaments of high-strength fishing, cooperate in pairs by 16 line thighs, the line thigh intersects mutually to intert to be woven into and wears 2 strands and press 2 strands of flower joints during braiding, the lay pitch 20mm of netting twine～40mm, the core in the weaving thread is 30～40 with silk quantity.

The utility model not only adopts high-strength fishing to improve the intensity of braided wire with monofilament with polyethylene monofilament, and by size and the core silk quantity of the traditional braided wire of adjustment, thereby improve the mechanical property of weaving thread and the circularity of weaving thread cross section with strand count amount, the lay pitch.The result shows through mechanical test, and diameter 3.0mm high-strength fishing improves 27.8%, improves 56.5% than the common three bursts of fishing of diameter 3.2mm with the polyethylene Grade A index of twisting thread with the woven polyethylene line than the common fishing of diameter 3.3mm with the ultimate strength of woven polyethylene line.

Description of drawings

What accompanying drawing was represented is a kind of high-strength fishing woven polyethylene line structure schematic diagram.

The specific embodiment

High-strength polythene filament is to make masterbatch by blend such as high density polyethylene (HDPE) (HDPE) raw material and auxiliary agents together, again with above-mentioned masterbatch with after the HDPE raw material mixes, the material that a kind of high-strength fishing that adopts self-reinforcing process to produce is used with the woven polyethylene line, its fracture strength index is not less than 6.9cN/dtex, the knot strength index is not less than 4.1cN/dtex.

The lay pitch h of netting twine when the utility model (seeing accompanying drawing) is determined the system line according to made high-strength fishing with the specification of

woven polyethylene line

1,3 usefulness the fishing high-strength fishing of system line thigh wear the quantity of several strands of several bursts of pressures when weaving with number of share of stock, core 5 a usefulness quantity and the netting twine of the quantity of polyethylene monofilament 4, line thigh 3; For example cooperate in pairs by 16 line thighs 3, mutually intersect and intert the weaving thread 1 that braiding forms, to adopt the quantity of 20mm～40mm, every line thigh 3 usefulness fishing high-strength polythene filaments 4 be 2～6, core 5 usefulness high-strength fishing to the lay pitch h of netting twine with polyethylene monofilament quantity is that 30～40, netting twine are woven into and wear 2 strands and press 2 strands to spend and save 2 during the system line.

The lay pitch h of and for example a kind of high-strength fishing netting twine during with woven polyethylene line system line adopt 30mm, every line thigh 3 usefulness high-strength fishing with the quantity of polyethylene monofilament 4 be 4, the number of share of stock of line thigh 3 be 16, core 5 usefulness high-strength fishing with the quantity of polyethylene monofilament 4 be 36, when netting twine weaves, cooperate in pairs by 16 line thighs 3, intersect mutually to intert to be woven into and wear 2 strands of flower joints of 2 bursts of pressures.

The utility model combines the core of high-strength fishing with line thigh, the lay pitch and the specific quantity of polyethylene monofilament material and specific quantity, makes the more common fishing of mechanical property and improves more a kind of high-strength fishing woven polyethylene line with woven polyethylene line, common three bursts of fishing with the polyethylene Grade A index of twisting thread.
