Ultra Cross knotless netting is a highly advanced 4-strand, braided, continuous, monofilament knotless netting used for heavy duty Commercial fishing applications. With our manufacturing process, Ultra Cross netting delivers superior strength and performance over conventional netting and therefore maximises the use of Dyneema®, High Tenacity Polyethylene and Nylon or Polyester fibre attributes.
The aggregate resistance of knots in standard netting is considerable and becomes an important factor where water flow through the mesh is a concern.
Without knots, Ultra Cross netting does not have raised spots to abrade on stern ramps, ship rails, net rollers, or even rough bottom. In the case of purse seines, the netting runs very smoothly as there is no inter-knot friction.
Less twine is used to make the meshes, which in some cases can mean a saving of 50% of the raw material. Without knots, the bulk of the netting is also reduced. A single layer of Ultra Cross can replace two or three layers of double knotted netting, reducing bulk and weight and therefore improve the "fishability" of a net.
Knots can tighten or distort throughout the life of netting, dramatically changing mesh size. Hollow braided twines can hold sediment which not only wears on the twine from the inside, but also changes mesh size. Ultra Cross netting maintains nearly 100% of its original mesh size throughout the life of the product, does not hold sediment because of the 4-strand braiding process, and has no knots to distort.
Ultra Cross netting has proven to be the best choice for square mesh and selective applications. The Danish Fisheries Institute, the Institute of Marine Research in Bergen, the National Research Institute of Fisheries in Japan, and many other fishery agencies around the world have endorsed Ultra Cross Knotless netting as the ideal square mesh material. Ultra Cross is also used where size selectivity is important for onboard mechanised fish handling systems, where a specific size fish is targeted to maximize machine efficiency.
The unique 4-strand makeup of Ultra Cross netting produces a very stable twine. This twine resists fraying and broken bars do not unravel.
Ultra Cross netting is very kind to fish with less bruising and abrasion from knots. This fact has been proven in many of the world’s fisheries where product quality cannot be compromised.
Distortion and tearing are major concerns in webbing. The 4-strand braid configuration of Ultra Cross results in a positive lock at strand intersections, virtually eliminating netting distortion and slippage of the intersections. Such a positive lock cannot be obtained with Twisted Cross netting which utilises a 2-strand twist formula. Because of its inherent stability and resistance to slippage, Ultra Cross is ideal for mesh size regulated fisheries, and is easy to repair even if a mesh breaks.
Although made up of a different number of strands, the total number of fibres used to make the strands for Ultra Cross and Twisted Cross are the same. If each strand of Twisted Cross consisted of 500 fibers, then each strand of Ultra Cross would group 250 fibres. The total number of fibres used to make one 2-stranded twist and one 4-stranded braid would be 1000 each.
There is, however, a difference in diameter between a 2-stranded twist and a 4-stranded braid. The diameter of a 4-stranded Ultra Cross braid is smaller because it is more compact than the bulky 2-stranded twist of Twisted Cross netting. A smaller diameter equates to reduced towing and sinking resistance.
