Mesh (textile)

Knotted nets for fishing

A net is a large-meshed textile fabric with regular meshes or openings. The meshes or openings can, for example, be rhombic , square or hexagonal .

Knotted and knotless nets

Historical net production

Traditional networks are prepared that already twisted or braided yarn at the crossing points of the network link is. A net needle or a net knitting machine can be used for this.

However, knotless networks are also known. Such knotless nets can be, for example, knitted fabrics in which the webs of the netting are connected by a mesh connection. A Raschel machine , for example, can be used to produce a knotless network .

Knotless nets are smoother when rubbed.

Thermoplastically produced networks

Mesh-like tarpaulins are made from stable tarpaulin, through perforation and 2-dimensional tugging of the material. Typically with almost round openings about 3 cm in diameter and 2 cm wide, often orange as a protective railing on construction, fall protection when skiing, against snowdrifts on roads. Almost as smooth as the film itself when rubbed against clothing.

Particularly fine-meshed bird and cat protection nets, which are also used for balloon rain , typically have a weight of only 7 g / m ² and are made of thin but solid thermoplastic.

history

The oldest finds of nets go back to the Mesolithic . However, since there are hardly any sites in which the organic material could withstand nets in the past, it cannot be ruled out that nets were already known in the Upper Paleolithic .

species

Networks are used in a wide variety of application areas. Accordingly, there are a number of different network types, for example:

• Tree packing net z. B. for Christmas trees see also: Netzmaschine
• Fishing nets and nets for fishing, nets for catching birds
• Networks for the agricultural sector, e.g. B. Bird protection nets
• Packaging and protective nets in the transport sector, e.g. B. the Girsack
• Shopping networks
• Sports networks, e.g. B. goal net, tennis net, backstop netting
• Mosquito nets
• Hairnets
• Safety nets for occupational safety
• Working platform nets as a replacement for scaffolding
• Camouflage nets
• Fog trap nets for drinking water production ( Atrapanieblas )
• Clothing with a net-like fabric
• hammock
• Railing net on sailing ships
• Hernia mesh : plastic mesh (made from polypropylene, for example) to close or prevent hernias
