Twine is a small sized cord. It can be any fiber from hemp to nylon and is used for anything where things need to be bound or secured but a big break strength isn’t needed.
For a long lasting twine, it’s best to use either a nylon or polyester fiber since both these synthetic fibers stand up well to UV and have great abrasion resistance.
At Quality Nylon Rope we have 2 sizes of twine available, both made of premium polyester fiber. 1 is a #2.25 / 1.8mm Twine and the other is a 3/32″ / 2.4mm Twine.
