Which Fiber is Best For Fishing Net Production – Nylon or Polyethylene?

Nylon and Polyethylene are the two most common fibers used in netting.  Both have advantages and disadvantages:

Nylon fiber has been in common use longer than polyethylene

Nylon fiber is elastic and will stretch (up to a point) before it breaks

Nylon is stronger and has a higher tensile (breaking) strength than common polyethylene fiber

Nylon will sink in water and will not float

Untreated nylon netting is softer and less stiff or rigid than polyethylene

Nylon is usually more expensive per pound or kilo than polyethylene

Nylon is usually manufactured (extruded) a white color and must be dyed if a different color is desired

Various netting treatments (bonding, dips, tar, etc.) will adhere to nylon fiber well

Polyethylene (also known as Poly) is not elastic and will stretch very little before it breaks

Commonly used polyethylene fiber is not as strong as nylon and has a lower tensile (breaking) strength.  Note: there are Ultra High Molecular Weight Polyethylene fibers that are very strong and very expensive.

Polyethylene will float on the surface of the water and will not sink

Commonly used polyethylene fiber is less expensive per pound or kilo than nylon

Color is added to polyethylene resin and does not need to be dyed. Once the fiber is made, the color cannot be changed and netting treatments do not adhere to the surface of polyethylene very well.

Because the fibers in polyethylene are larger in diameter or size than fibers in nylon, polyethylene is more abrasion-resistant but is stiffer or more rigid than untreated nylon
