Polyethylene netting is an extremely popular and versatile netting type. Double Diamond polyethylene netting has many applications including the following:
P/E netting is long lasting, UV protected, and extremely tight knotted to ensure the integrity of the net over time. The netting is “double salvaged” – indicating that one row on the top and bottom of the net is double reinforced, to ensure higher strength at a nets weakest point.
Polyethylene netting is generally available in both square and diamond mesh shapes. It is generally measured as a stretched lengthwise bundle, but from time to time can be measured depthwise. It is available in dark and light green, blue, orange and black. Our sapphire polyethylene, which is very popular in the commercial fishing industry, is easily recognized as blue with a yellow tracer (fleck) in the yarns.
The polyethylene nets are listed as:
For example: 400/21 2″ 100 x 20
400 = denier or material / 21 = the ply or thickness (3 strands with 7 yarns in each strand, 3 x 7 = 21 ply)
2″ = the stretched mesh size
100 = the metres
20 = the number of meshes deep
Some manufacturers claim high twine breaking strength as a critical parameter in assessing the quality of a net, but we believe that the ultimate test of nets is in optimizing knot breaking strength and twine abrasion as the nets fail in knots and by abrasion and not by straight breaking of twine. Sapphire nettings deliver supreme “Knot Breaking Length”, combining two key attributes of “Knot Breaking Strength” and “Twine Runnage”. Net makers and skippers can now either downsize the twine size and achieve economy in the fuel consumption or utilize the high strength for more demanding applications. Sapphire netting is designed for reducing the towing resistance, which in turn reduces the fuel consumption and increase the efficiency.
