When choosing netting twine to make fishing nets, net makers use many measurement systems. If you’re not familiar with the way twine and netting are denoted, it can be tricky to specify what you want. It can be even harder to make sure you’re specifying the right measurement for your project. To make it easy, we’ll explain. Here are the different measurement systems:
- Meter per kilogram ( M/kg)
- Yard per pound ( Yd/LB )
- International system ( Den )
- Millimeter system ( D/mm )
In our catalogue at Huaxing Nets, we use the Denier system for nylon twine and nets and the diameter/millimeter system for polyethylene twine. For certain kinds of trawls, we use the Tex system.
The International System
The international system is based on the weight per unit of length measured in “deniers”.
A denier is a weight in grams for a 9,000 metre length of twine. So if someone says something is “210 dens”, they mean that this 9,000 metre length of twine weighs 210 grams.
When you see a measurement like “210X3X4”, this means that the weight is 210 grams, the netting yarn is made of three strands, and each of those strands is made of four fibres.
The Diameter / Millimeter System
Polyethylene twines have a bigger diameter than polyamide or nylon strands, which is why we list polyethylene twines in diameter by millimetre.
Polyethylene diameters range from 0.05 mm to 6. mm. The largest diameters for polyethylene are considered rope, not twine.
Across our company, we use all of those synthetic fibres, but which one we choose for your net depends on what you need and where and how it will be installed.
So when you’re ordering a net, here’s the information you’ll want to specify:
- Kind of gear to build
- Size of the mesh
- Type of fibre
- Twine diameter
- Net colour
- Net dimensions
