Abstract
The ocean trawlnet escape compound fishing lines manufacturing method of release device, using synthetic fibers, heat-shrink tube, hot melt adhesive, fishing lines is made in synthetic fibers twisting, pyrocondensation inside pipe wall applies one layer of hot melt adhesive, shrinkable sleeve is heat-treated on synthetic netting line, pyrocondensation temperature is 50~120 DEG C, the pyrocondensation time is 10~60min, obtains the ocean trawlnet escape compound fishing lines of release device.Compound fishing lines of the invention can reduce injury of the fishing lines to mammalian epidermis, simultaneously because the integral rigidity of mesh sheet improves, so that mesh sheet after trawlnet release device is made, is convenient for operation.Further, since the surface of cable is smooth, the water filtering performance of fishing net tool can be improved in fishery operation, reduce the resistance of fishing net tool in water, reduce energy consumption when fishery operation.
Description
Technical field
The present invention relates to compound fishing lines systems used in compound fishing lines manufacturing method, especially trawlnet escape release device
Make method.
Background technique
Countries in the world require to install mammal escape release device on large-scale ocean trawlnet, to discharge the ocean accidentally caught
Mammal.It is currently used large size trawlnet escape release device be twisted thread synthetic fibers, mesh sheet made of knitmesh.The net
Fishing lines used in piece is usually that the synthetic fibers such as polyethylene, polyamide is used to twist thread.This traditional fishing lines by
In synthetic fibers twisting so that the surface of fishing lines is very coarse, when fishing net is made with this synthetic netting line, hold very much
Easily incised wound or scuffing accidentally catches the epidermis into the marine mammal of fishing net, jeopardizes the life for the marine mammal accidentally caught.This
Outside, epidermis of the mesh sheet made of this synthetic fibers in addition to marine mammal can be injured because of rough surface, since synthesis is fine
It is softer to tie up mesh sheet, can not come spread apart completely in water, operation difficulty is larger when discharging marine mammal, release effect
Fruit is unobvious.On the other hand, suffered resistance is also more obvious in water for this shaggy fishing net piece, has been not suitable with China pair
The requirement of fishery energy-saving and emission-reduction.
Summary of the invention
The present invention proposes a kind of ocean trawlnet escape compound fishing lines manufacturing method of release device, to solve to feed on trawlnet
The problem of fishing lines used in newborn animal escape release device damages mammal due to rough surface, realize safely, have
The purpose of mammal in effect release ocean large size trawlnet.
Technical solution of the present invention uses synthetic fibers, heat-shrink tube, hot melt adhesive, it is characterized in that synthetic fibers twisting is made
Fishing lines；Pyrocondensation inside pipe wall applies one layer of hot melt adhesive, and shrinkable sleeve is heat-treated on synthetic netting line, and pyrocondensation temperature is 50~
120 DEG C, the pyrocondensation time be 10~60min.
Outstanding feature of the invention is that one layer of heat-shrink tube is coated outside conventional synthesis fiber cable, improves the surface light of cable
Slippery.The compound fishing lines of cladding heat-shrink tube can reduce injury of the fishing lines to mammalian epidermis, simultaneously because mesh sheet
Integral rigidity improves, so that mesh sheet after trawlnet release device is made, is convenient for operation.Further, since the surface of cable is smooth,
The water filtering performance of fishing net tool can be improved when fishery operation, reduce the resistance of fishing net tool in water, reduce energy when fishery operation
Consumption.
