Fishing Net

  High-Performance Twisted Knotless Net

 

  With the national high performance fiber industry development strategy-oriented, and promotion of emerging application requirements for lead of marine economy, Our company has been engaged in research and development of technology for production of high performance and low cost ultra high molecular weight polyethylene fiber, has developed and industrialized high performance twisted knotless fishing net on the basis of high strength polyethylene fiber, which can meet modern marine ocean fishing, deep sea cage-breeding of our country, and achieve the rapid development of energy-efficient deep health cultivation.

 

  Ultra high molecular weight polyethylene (UHMWPE) fiber is one of three high performance fibers, and has been identified by the state council as speeding up the cultivation and development of strategic industries. It has the advantages of high strength, low density, high modulus, non absorbent, strong anti UV, anti aging, anti impact cutting toughness and resistance to seawater and all kinds of chemical corrosion and other excellent performance. It is mainly used in the fields of national defense military equipment: such as soft body armor, lightweight bulletproof helmet, armor plate; In order to expand UHMWPE fiber’s application in the marine field, our company has researched and developed low cost colored UHMWPE fiber production technique and has realized industrialization.

 

  With the development of low cost, high performance ultra high molecular weight polyethylene colored fiber, the company, at the same time, has developed high performance twist knotless net production technology. Advanced technology is adopted in producing the net (Only Japan mastered the technology before). With the technology, the fiber strength’s utilization increases by 40%. The fiber has the advantage of high strength, smooth surface and flat net knot. While maintaining equal tension strength and the same price, mesh density of UHMWPE fiber twisted

 

  knotless net is only about 1/10 and 1/8 of common polyethylene fiber warp net.

  Ultra high molecular weight polyethylene fiber twisted knotless net’s application in marine fisheries:

 

1. Ideal for sea fishing net and deep-sea fishing large trawls for its fine cable, for its advantage of high strength, small water resistance; and can also prevent ice cutting and knife cutting, greatly improving the off-shore fishing safety.

2.suitable for deep-sea cage breeding, for its advantage of fine cable, high tenacity, small water resistance and resistant to violent typhoon attacks; at the same time, its smooth surface can sufficiently prevent algae and shellfish reproductive, avoid fish biting; good resistance to sea water, chemical corrosions, and anti-aging performance, shell life increases by 2-3 times, thus can reduce the artificial feed on fish, improve fisheries quality, increase the income of fishermen, and effectively protect the green, low carbon marine environment.
