What Is Monofilament?

DuPont began producing nylon monofilament in 1939, but found that nylon was wiry, and hard to tie knots.  In 1958 DuPont introduced Stren®, made from mixing and melting a variety of polymers and then extruding (forcing) the polymer mixture through tiny holes, forming long, single strands of line.  The thicker the line, the higher the tensile strength (pound test). Most monofilament is high density, which affects how it can be recycled.

Turf reinforcement mesh, or sod netting, is frequently composed of high density plastic, or extruded polymers much like monofilament.  Sod netting is primarily used to stabilize the grass, or turf, on sports fields, right-of-ways, parking lots, retention pond banks, and areas of high erosion, and dense, heavy traffic.  The netting provides stability and protection to newly sodded areas, and promotes quicker use, with much more traffic than normal seeding, or sod placement without the netting.
