6 Major Types of Knotless Netting

Knotless netting is net fabric without knots by interweaving strands or threads. According to the manufacturing process, it can be divided into 6 major types, that is, warp knitted netting, twisted knotless netting, plain netting, Leno/Gauze weave, plastic moulding netting and super knot netting. Here we'd like to introduce every process, features and applications.

Warp knitted netting structure diagram
Warp Knitted Netting

It is a net fabric composed of two adjacent strands or threads to form loops along the longitudinal direction of the net (warp direction), and alternately knitted with each other, so it is also known as Raschel net. It is produced by warp knitting machines and is made of PE monofilament yarns, PA multifilament yarns, PET multifilament yarns, PP multifilament yarns, etc.

Features

  • Stable mesh size (warp knitted netting has a compact structure and net joints are interlocked. It is not easy to loose and deform after shaping, therefore, it ensures stable mesh size and the mesh is not easily deformed);
  • Good wear resistance and high strength net fabric (it overcomes the shortcoming of large strength loss of knotted net joints and the net fabric maintains a large retention rate of mesh strength);
  • Smooth surface and will not rub the fish body and is suitable for being used as fish cultivation net or fishing net.
  • Easy to clean and quick to dry;
  • Under the same area conditions, it is light weight due to the lack of knots. The net fabric and its associated netting is small sized and easy to operate;
  • Low cost (There are no knots, so the warp knitted netting consumes less thread and is lighter in weight. Its lightweight, short processing period and reduced twisting process make it can be knitted into net after warping, leading to a low cost);
  • The mesh can be woven into small sizes. It has a wide range of applications compared with other nets;

Application

In the fishing industry, it is mainly used as cage nets, purse seines and scallop cultivation nets. In addition, it is also used as construction safety net, dust control nets, anti bird nets, wind protection nets, sun shade nets and vegetable nets, etc.

Twisted Knotless Netting

It is a net fabric composed of two adjacent strands after interweaving and twisting. It can be made of PE monofilament yarns, PA multifilament yarns, PET multifilament yarns, PP multifilament yarns, etc.

Features

  • Less material consumption;
  • High strength in vertical and horizontal directions;
  • Small water flow resistance;
  • Stable mesh size

Application

In the fishing industry, it is mainly used as cage nets, purse seines, etc.

Plain netting structure diagram
Plain Netting

It is a plain cloth like net fabric interwoven by alternative warp and weft strands. It is mainly made of PE monofilament yarns.

Features

  • Simple organization structure;
  • Good water filtration;
  • Flat and smooth net surface.

Application

It can be used as insect screens, package bags, etc.

Leno/Gauze weave structure diagram
Leno/Gauze Weave

It is net fabric made by inserting weft threads into warp threads after twisting. It is mainly made of PE monofilament yarns.

Features

  • Flat, smooth net surface;
  • Solid texture;
  • Stable mesh structure, not easy to move.

Application

Currently, it is mainly used for silverfish fishing, shrimp farming, shellfish farming, eel farming, lobster farming and crab farming.

Plastic Moulding Netting

It is a net fabric formed by directly extruded thermoplastic synthetic material after drawing. It is generally made of PE, PET and PA.

Features

  • Wear resistant;
  • Corrosion resistant;
  • Good resilience.

Application

In agriculture, it can e used as chicken netting, plant climbing nets, anti bird nets. In addition, it is also widely used in aquaculture and other fields.

Super knot netting structure diagram
Super Knot Netting

It is a net fabric made of two adjacent yarns after crossing and braiding. It is generally made of PA and PP multifilament yarns.

Features

  • High strength;
  • Low fraction and high wear resistance;
  • Small size and light weight;
  • Stable mesh size;
  • Reduced damage to fishes;
  • Reduced deformation and tear.

Application

It is suitable for used as trawling and aquaculture netting.
