Marine Netting Comparison

Comparison between Twisted Knotless construction & Knitted Raschel nettings.

Twisted Knotless netting, used by Smart Net Systems, is composed of two sets of twisted filaments that are going in the same direction to, and including the joinings. This results in no loss of strength.	Knitted Raschel (Braided) type netting is constructed with the filaments in a series of knots that are woven together. The diagram demonstrates the way the filaments change direction at the joinings. This results in a strength loss in the average range of 30 percent of the tensile rating of the filaments.

Advantages of knotless twisted polyethylene:
	Finished nets much stronger than knotted
	Nets less likely to stretch as there are no knots to pull tight.
	No knots to wear out on bottom contact.
	15% less drag than knotted Up to 12% fuel savings.
	Option of towing a larger net with same H.P.
	Easier to spread

Twisted Knotless Netting

Nitto Seimo knotless netting first appeared on the world market in 1925 when the Nitto Seimo Co., Ltd., founded by Mr. Teruasa Kobayashi, invented the Knotless Twisted Net weaving machine.

Nitto's Knotless nettings have virtually replaced both Raschel and Knotted nettings in the Purse Seine fishing and Trap net fishing industries in Japan.

Nowadays, the use of our Knotless nettings has been expanded to Trawl fishing, Aquaculture, Marine fish transportation, and the various ground-use purposes such as Golf-Driving ranges, Batting-practice cages and backstops and more.

Smart Net Systems is based in North America and provides netting and technical assistance in the USA and Canada.
