Abstract
The present invention relates to staple fibre field, the compound fishing lines manufacture method of specifically a kind of bottom trawlnet, using synthetic fibers, hot melt glue fiber, synthetic fibers are twisted together with hot melt glue fiber fishing lines is made, then heat setting processing is carried out to fishing lines, heat setting temperature is 50~120 DEG C, thermo setting time is 10~60min, that is, ocean bottom trawlnet is made with wear-resisting compound fishing lines.The wear-resisting compound fishing lines of the present invention can improve fishing net tool anti-wear performance, simultaneously because hot melt adhesive curing, which bonds synthetic fibers, make it that the integral rigidity of mesh sheet is improved, the water filtering performance of fishing net tool can be improved in fishery operation, reduction fishing net has the resistance in water, energy consumption during reduction fishery operation.
Description
Technical field
It is a kind of wear-resisting compound fishing lines manufacture method, especially far specifically the present invention relates to staple fibre field
The complex abrasion-proof fishing lines manufacture method that fondothem trawlnet is used.
Background technology
Current fishing net material is based on the synthetic fibers such as polyethylene, polyamide, polypropylene, polyester, ocean trawlnet, especially
Be ocean bottom trawlnet in fishery operation, the damage for scraping and causing trawlnet occurs for trawlnet bottom and seabottom geology.In reality
In production, the destruction of ocean trawlnet and the abrasion for mostling come from trawlnet with seabed in operation process is scrapped, therefore trawlnet
Service life depends primarily on the anti-wear performance of its netting gear.Existing fishing net improves sth. made by twisting during mainly passing through fishing lines twisting
The method of degree improves its anti-wear performance, but the decline of fishing lines fracture strength can be brought simultaneously by improving the fishing lines twist, and
The loss and the increase of its twist of fishing lines fracture strength are proportional.
The content of the invention
It is remote to solve it is an object of the invention to provide a kind of ocean bottom trawlnet with wear-resisting compound fishing lines manufacture method
Fondothem trawlnet causes the problem of trawlnet ruptures because trawlnet contacts generation friction with seabed, improves ocean in fishing operation
The durability of trawlnet during fishing operation.
The first aspect of the present invention is there is provided a kind of compound fishing lines manufacture method of bottom trawlnet, using synthetic fibers, heat
Fishing lines is made in melten gel fiber composite, comprises the following steps：
(A) synthetic fibers are twisted fishing lines are made together with hot melt glue fiber first, described synthetic fibers number of share of stock with
The ratio of PUR number of fiber is 2：1~16：1；
(B) fishing lines and then by step A obtained carries out heat setting processing, obtains described bottom trawlnet with compound fishing net
Line.
Described synthetic fibers are hdpe fiber, Fypro (nylon 6 fiber or nylon 66 fiber), gathered
One kind in tacryl, polyester fiber.Described synthetic fibers are all conventional fishing fibers, by the polymer former material bought
Material can be prepared by through melt spinning processing, and for example hdpe fiber can be by Yangtze petrochemical industry or Daqing petrochemical, the trade mark
5000S high density polyethylene (HDPE) section is made through melt spinning.
Described hot melt glue fiber is one kind in polyurethane fiber or EVA hot-melt adhesive fiber.
It is preferred that, described polyurethane-hot melt glue fiber may be selected from：Bostik companies 9224F polyurethane-hot melt glue fibers.
Described EVA hot-melt adhesive fiber may be selected from：E.I.Du Pont Company's EVA 150W EVA hot-melt adhesive fibers.
It is preferred that, diameter 3mm~15mm of fishing lines made from described step A.More preferably a diameter of 3~5mm.Work as fishing
(more than 8mm) when sealike colour is larger, PUR can not preferably bond the fiber in fishing lines during heat treatment.
In described step B heat setting temperature be 50~120 DEG C, thermo setting time be 10~60min.When temperature is relatively low,
PUR can not fully melt；Temperature is too high, and the compound fishing lines hardness after heat treatment is larger, under the aft-loaded airfoil performance of fishing lines
Drop.
It is preferred that, in described step B heat setting temperature be 80~100 DEG C, thermo setting time be 20~30min.
There is provided a kind of bottom trawlnet compound fishing lines, the compound fishing of described bottom trawlnet for the second aspect of the present invention
Netting twine is prepared using above-mentioned manufacture method.
The invention has the advantages that：
1st, outstanding feature of the invention is conventional synthesis fiber netting twine and PUR fiber composite, and hot melt glue fiber is in Re Chu
Synthetic fibers are bonded together during reason, the cohesive force of synthetic netting line are improved, so as to improve synthetic netting
The anti-wear performance of line.Further, since synthetic fibers are bonded together by PUR, the whole of the thread Trawl of fishing net is combined
Body is rigidly improved, and the water filtering performance of trawlnet netting gear can be improved in fishery operation, and reduction fishing net has the resistance in water, reduction
Energy consumption during fishery operation；
2nd, wear-resisting compound fishing lines of the invention can improve fishing net tool anti-wear performance, simultaneously because hot melt adhesive curing is bonded
Synthetic fibers make it that the integral rigidity of mesh sheet is improved, and the water filtering performance of fishing net tool can be improved in fishery operation, reduce fishing net
Have the resistance in water, energy consumption during reduction fishery operation.
Embodiment
