ROPES
There are two types of fibers used in the construction of ropes and twines, natural and synthetic. The most common natural fibers used are Manila, Sisal, Jute, and Cotton, while synthetic fibers such as Polypropylene, Polyethylene, Nylon, and Polyester have beome the most popular in today's market.
POLYPROPYLENE & POLYETHYLENE make a flexible and lightweight rope. They are
rot proof, resist oil, water, gasoline, and most chemicals. They are the only rope
fibers that float. Available twisted or braided, they are a perfect economical
choice as a general purpose rope.
POLYESTER is very strong and provides excellent abrasion resistance. Polyester
stretches less than nylon, so it does not have the elasticity of shock absorbing
qualities that nylon does. It has good resistance to UV rays, and resists rot, oil,
gasoline, and most chemicals. It is very popular as a marine or industrial rope
where stretch is not desired.
NYLON is known for its elasticity and tremendous shock absorbing qualities. It has
good abrasion resistance, is rot proof, resists oil, gasoline, and most chemicals. It
has good resistance to UV rays. Nylon will last 4-5 times longer than natural fibers.
MANILA ROPE was once the preferred choice in ropes before the synthetic fibers
were developed. Manila ropes still maintain some advantages to synthetic fibers.
It is not affected by heat, and has an excellent resistance to the suns UV
(Ultraviolet) ray
SISAL fibers come from the Agave and Sisalana plants grown in some tropical
countries. Sisal has many of the characteristics of manila, but offers only 80% of its
strength. It is more economical than manila, and makes a good choice as a
general purpose rope. It is commonly used as a tying twine.
JUTE is mainly used as a tying twine. It knots very well. Due to its short fibers, it does
not have much strength.
COTTON is natural fiber, typically white in color. It is a soft fiber, which makes it
nice to handle. It also knots very well.
