Nylon
Offers high tensile strength, high elasticity, energy absorption & impact resistance, high melting point
Polyester
Offers high tensile strength, low elastic elongation, high melting point (approx. 480) and good abrasion resistance.
Polypropylene (Multifilament)
Soft and flexible and has the feel of nylon. Strength is about ½ of nylon with a low melting point (approx. 330). It is a light-weight fiber with high positive buoyancy which allows it to float.
Polyethylene
Similar to Polypropylene fiber, retains memory and slicker than polypropylene. Has better UV protection. Heavier than Polypropylene and offers more abrasion resistance. It also has high buoyancy.
Cotton
Offers wicking ability, soft non-scouring surface and superior knot retention.
