Problems solved by technology

During the development of net gear, some technical problems that need to be solved urgently have been exposed, such as the problem of anti-marine biofouling of net gear and net clothing, direct connection and contact between net gear and net clothing and posts (customarily referred to as between net posts) The problem of wear and tear, the problem of poor water exchange inside and outside the nets and nets, and the escape of fish stocked in the nets and nets, etc., the potential threat of the above problems is great, which seriously affects the breeding benefits of marine ranches or large-scale breeding nets. Therefore, marine The processing method of large-scale nets with double-layer structure in the field of pasture embankment or large-scale breeding net engineering technology is a technical problem that has not been solved for a long time in this technical field

Embodiment Construction

[0009] The best way to implement the present invention is illustrated below in conjunction with the accompanying drawings:

[0010] The invention adopts ultra-high molecular weight polyethylene fiber, ultra-high molecular weight polyethylene braided thread and fishing net antifouling agent, and is characterized in that the ultra-high molecular weight polyethylene fiber with a linear density of 1610D is warped into an ultra-high molecular weight polyethylene fiber with a linear density of 1610D. Vinyl fiber yarn, and then 16 ultra-high molecular weight polyethylene fiber yarns with a linear density of 1610D are used for warp The knitting machine is processed into a small-mesh ultra-high molecular weight polyethylene warp-knitted net with a specification of "UHMWPE-1610D×24-44"; the small-mesh ultra-high molecular weight polyethylene warp-knitted net is treated with antifouling agent for fishing nets, After drying, the antifouling treated small-mesh ultra-high molecular weight pol...

Abstract

A processing method for large netting gear clothes of a double-layer structure is characterized in that a small mesh ultra-high molecular weight polyethylene warp knitting net and a large mesh ultra-high molecular weight polyethylene warp knitting net are processed respectively; a head line is arranged on the upper edge in the length direction of the small mesh ultra-high molecular weight polyethylene warp knitting net which is 492m*11m and goes through anti-dirty treatment, and a foot line is arranged on the lower edge; a head line is arranged on the upper edge of the large mesh ultra-high molecular weight polyethylene warp knitting net which is 492m*11m and goes through anti-dirty treatment, and a foot line is arranged on the lower edge; the head line of the small mesh ultra-high molecular weight polyethylene warp knitting net which goes through the anti-dirty treatment and the head line of the large mesh ultra-high molecular weight polyethylene warp knitting net which goes through the anti-dirty treatment are bound into a head line of the large netting gear clothes of the double-layer structure; the foot line of the small mesh ultra-high molecular weight polyethylene warp knitting net which goes through the anti-dirty treatment and the foot line of the large mesh ultra-high molecular weight polyethylene warp knitting net which goes through the anti-dirty treatment are bound into a foot line of the large netting gear clothes of the double-layer structure.

Description

technical field [0001] The invention relates to a large-scale net gear processing method in the technical field of marine pasture dams or large-scale breeding net enclosure engineering. Background technique [0002] The concept and technical content of the net gear in the technical field of marine pasture dams or large-scale aquaculture net enclosures are far from fishing gear and aquaculture cages. The net processing method in the field of fishing gear and the net processing method in the field of aquaculture net cage technology The methods are not applicable to the large-scale netting netting processing method of the double-layer structure in the marine pasture dam or the large-scale breeding net engineering technical field. Because of the different aquaculture methods and stocking fish specifications, the mesh size of the nets varies greatly; according to the size of the mesh, people call the nets with a mesh size of no more than 50mm small mesh nets or small mesh nets. ...
