Description

Tubular kernmantle of a kind of fishing high-strength and braid method thereof

Technical field

The present invention relates to tubular kernmantle of a kind of fishing high-strength and braid method thereof in the aquatic products technical field.

Background technology

Rope is the widely used materials in field such as fishery, boats and ships and military affairs.By structure, rope can be divided into torsade and kernmantle.And kernmantle can be subdivided into tubular kernmantle and 8 strands plaited rope by structure.Tubular kernmantle is meant by the regular rope that is woven into tubular structure of some rope strands.Wherein, at the wire rope core that is called of the filler of tubular kernmantle central part configuration, the rope strand braid that is wrapped in wire rope core outer tubular structure is called tubular kernmantle face.Tubular kernmantle is important fishing rope material, and its sorting technique is a lot, has or not by central part and fills out core and be divided into tubular kernmantle of core and the tubular kernmantle of centreless are arranged; Be divided into 4 femoral canal shape kernmantles, 6 femoral canal shape kernmantles and 8 femoral canal shape kernmantles etc. by number of share of stock; Be divided into the tubular kernmantle of polyethylene, the tubular kernmantle of polyamide and the tubular kernmantle of polyester etc. by rope making with matrix material; Be divided into common tubular kernmantle and high-strength tubular kernmantle by intensity.Along with tubular kernmantle machine industrial expansion, advantage such as tubular kernmantle is high-strength, wear-resisting with it, compact conformation and knotted netting size of mesh are stable obtains the position of a seat gradually in modern times in the fishery.Small dimension 16 femoral canal shape kernmantles between diameter 4mm～8mm are to use wider knotted netting material in the domestic and international large-scale trawl-net fishing, and in addition, it is also as aquaculture net cage guiding principle rope or all kinds of fishing gear rete cord.

Current fishing is with in the tubular kernmantle processing, the general not filling wire rope core at the center of tubular kernmantle, this cause all rope strands outside the masterpiece time spent be prone to the rope metaboly takes place, reduced the security of fishery.In addition; With polyethylene in the tubular kernmantle processing enterprise, tubular kernmantle uses monofilament also comparatively single as common polythene monofilament, tubular kernmantle technology in existing fishing, and polyethylene monofilament is as the rope matrix material of tubular kernmantle; Mainly process at present through traditional melt-spinning technology; Common polythene monofilament high-class product fracture strength standard index is 5.60cN/dtex, and the common polythene filament strength is lower, and the brute force of the tubular kernmantle of its braiding is also lower.Tubular kernmantle technology is directly connected to the physical property of rope; If processing technology imperfection; Will have a strong impact on the physical and mechanical properties of rope, therefore, tubular kernmantle of a kind of fishing high-strength and processing method thereof have also just become the urgent technical barrier that solves of people in the prior art field.

Summary of the invention

The technical issues that need to address of the present invention are under the situation that does not increase tubular kernmantle nominal diameter, to improve outward appearance, cost performance, cross section circularity and the mechanical property of the tubular kernmantle of fishing high-strength, to satisfy the Modern Fishery needs.

The technical scheme that the present invention adopts is: the tubular kernmantle of a kind of fishing high-strength; Comprise wire rope core and be wrapped in wire rope core outer tubular structure kernmantle face; It is characterized in that: described wire rope core quantity adopts 1 strand at least, and per share wire rope core uses yarn to adopt fishing to use the doubling under the situation of not twisting of superhigh molecular weight polyethylene fibers long filament to use the ultra high strength polyethylene fiber filament yarn as line density as the fishing of 4000D; Described kernmantle face adopts the braiding of 16 strand to form, and said rope strand uses yarn to adopt fishing to use the doubling under the situation of not twisting of polypropylene fibre long filament to use the polypropylene fibre filament yarn as line density as the fishing of 2000D.

The tubular kernmantle of above-mentioned fishing high-strength, its nominal diameter are 4mm.

The braid method of the tubular kernmantle of above-mentioned fishing high-strength is:

Keep tension force of the same size weaving on the bobbin with yarn rope strand or wire rope core, thereby obtain rope strand or wire rope core braiding bobbin around being around on the pipe machine;

Choose the corresponding pickwheel of tubular kernmantle machine by the pitch of 24mm; 16 rope strand braiding bobbins are placed respectively on the bobbin ingot of 16 bolster shape kernmantle machines; 4 wire rope core braiding bobbins place on the ingot iron of tubular kernmantle machine bottom; Line density on 4 wire rope cores braiding bobbin is the fishing of 4000D and introduces in the medium pore of tubular kernmantle machine bottom with the ultra high strength polyethylene fiber filament yarn, and draws from weaving thread guide eyelet;

Start braiding keeps the equalization of strain between each rope strand during braiding, between rope strand and the rope strand each other interlacing become tubular kernmantle face, wire rope core then is filled in the central authorities of tubular kernmantle.

The tubular kernmantle of fishing high-strength provided by the present invention shows through the mechanical test result; Under equivalent diameter; This nominal diameter is that the disrumpent feelings brute force of the tubular kernmantle of fishing high-strength of 4mm is up to 4639N; The fishing of existing same diameter is improved largely with the polyethylene rope brute force, and the elongation at yield rate of the tubular kernmantle of this fishing high-strength is 12% simultaneously, and percentage elongation meets the fish production needs.The present invention combines fishing with superhigh molecular weight polyethylene fibers long filament and special tubular kernmantle technology with polypropylene fibre long filament, fishing effectively, has effectively improved outward appearance, cost performance, cross section circularity and the mechanical property of the tubular kernmantle of fishing high-strength.
