FIBERS & TYPES
Round single-braid rope construction
designed to offer high strengths and ease of splicing. Single braids
offer significant improvement in performance over twisted and
eight-strand plaited ropes.
Traditional rope construction
consisting of three equally sized strands twisted together to produce
a very fine, durable rope. Standard designs are available in nylon,
polyester, polypropylene, and specialized blends.
A uniquely designed rope which combines polyester
and polypropylene/polyethylene fibers together. This design combines the
durability and high abrasion resistance of polyester with the light weight
of polypropylene/polyethylene. Most manufacturers have brand names for
these ropes such as Hi-Power, Poly-Plus, Combo-Plus.
For handling quality, cotton is hard to beat. It is
soft and pliable, and easy on the hands. Being a natural fiber, it does not
have the strength or durability of synthetic fiber ropes. It is used for
sash cord, clothesline, and Venetian blind cord.
DuPont's trade name for
their polyester fiber. Much less elastic than nylon, with slightly
lower strength. Not affected by common alkalis or acids. Excellent
U.V. resistance. Very good wet or dry abrasion resistance.
rope construction composed of a core braid containing within an outer
braided jacket. Double braids are torque-free, have very good abrasion
resistance, and offer excellent strength to weight ratios. Ropes are
available in nylon, polyester, and combinations of fibers, including
Kevlar® and Spectra®, that are designed to maximize the advantages
inherent in different fiber classes.
A gold and white colored Braid-On-Braid nylon rope,
consisting of a braided jacket over a braided core. Combines excellent
performance, spliceability and handsome appearance. This jacket has
alternating white and gold yarns.
100% braided Kevlar®
core and blended spun filament polyester cover braid. This design is
intended to derive maximum benefit from the ultra high strength, low
stretch properties of Kevlar®.
Due to the susceptibility of Kevlar®
to abrade in bending situations, this construction is intended for use
in situations such as standing rigging where the rope is not subject
to excessive bending loads.
The best known natural fiber rope. At one time, it
was the best rope fiber available. Manila must be handled and stored with
care as any dampness will cause it to rot.
A combination rope
design in which each strand consists of a polypropylene core wrapped
with 100% polyester cover yarns made of blended staple and filament
fibers. Lighter and lower in strength then Dacron, but with similar
stretch characteristics. Excellent U.V. resistance.
The first synthetic fiber rope manufactured. Due to
its elasticity, nylon can absorb sudden shock loads that would break ropes
of other fibers. It has very good resistance to abrasion and will last four
to five times longer than natural fiber ropes. Nylon rope is rot proof and
not damaged by oils, gasoline, grease marine growth or most chemicals other
Nylon cover/nylon core.
Most elastic double-braid construction; has excellent energy absorbing
characteristics. Good abrasion resistance wet or dry. Minimal strength
loss due to U.V. Affected by strong mineral acids.
100% nylon 12-strand
single braid. Superior in strength and performance characteristics to
3-strand and plaited rope constructions. The single-braid design will
not rotate under load or hockle when a load is released. Stays firm
and round under load. Easy to splice. Strips and renders well on
winches and capstans. Designed to be used in place of 3-strand and
plaited ropes in all applications where improved performance is
construction consisting of a parallel fiber core wrapped with a double
layer of polyester tape and covered with a braided jacket. Unlike
other parallel core ropes, this rope is easily spliced using a
technique similar to that used for double braids. The parallel core
rope provides very high strength and exceptionally low elongation.
A very strong synthetic with excellent abrasion
resistance. Polyester does not have the stretch and elasticity of nylon.
Polyester is superior to nylon with respect to cycle loading and abrasion.
Also available with specially designed finishes to improve handling and
extend life in a harsh marine environment.
cover/polyester core. Very low elongating construction - much less
elastic than nylon. Excellent abrasion resistance wet or dry. Superior
resistance to U.V. degradation. Excellent chemical resistance except
to concentrated sulphuric acid and strong alkalis at elevated
core. Unique combination of fibers designed to provide a balanced rope
construction of extremely high strength. Stronger than either nylon or
polyester double braid, but offering elasticity similar to that of an
all nylon rope. The polyester cover braid offers the same excellent
abrasion and chemical resistance as found in the all-polyester rope.
100% polyester single
braid. Highest strength s-braid available. Provides all the advantages
associated with polyester in a torque-free, flexible construction.
A floating rope somewhat like polypropylene
but slightly heavier. Polyethylene's handling characteristics are a little
different than polypropylene. It is not quite as strong, size for size, but
has better abrasion resistance. It is available in twisted and hollow braid
A lightweight, strong rope that is
used extensively. It is a floating rope and is rot proof and unaffected by
water, oil, gasoline, and most chemicals. Polypropylene rope is available
in monofilament fiber, which is smooth surfaced, or multifilament fiber,
which has a somewhat velvety appearance and feel. New generation
polypropylene ropes have been developed which have superior strength and
abrasion resistance. Wellington markets this rope as Pro-Plus.
A Wellington registered trade name for
multifilament polypropylene rope. Available in either solid or diamond
braid and laid (twisted) construction.
A rope that is used primarily where strength and
durability are not important. It is softer and more pliable than manila.
Sisal is a natural fiber that deteriorates rapidly when exposed to weather.
core. The strength member core design utilizes the exceptional
performance properties of Spectra®.
High tensile strength, very low stretch, and lightweight. The tough
durable jacket provides excellent abrasion and chemical resistance.
The core is provided with a special coating to reduce slipping between
the cover and core.
Core braid consisting
of a combination of Kevlar®
fibers and a filament polyester cover. This design combines the best
properties of the two strongest, lowest stretch fibers commercially
available. Problems associated with the exclusive use of either of
these fibers, such as the poor abrasion resistance of Kevlar®
or the creep and excessive slipperiness of Spectra®,
are virtually eliminated through the special blending of these two
fibers in the core braid.
ULTRA HIGH MOLECULAR WEIGHT POLYETHYLENE (UHMWPE)
extended chain polyethylene fiber characterized by a very high and narrow
molecular weight distribution achieved by gel spinning of the polymer.
Combines tradition with progress. Unmanila is
constructed from polypropylene fiver with the rich, golden tan color of
manila rope. The surface of the rope has the texture of manila with soft
hair-like fibers protruding. Unmanila holds a knot extremely well and
provides excellent gripping surface to minimize slippage when held. It has
all the advantages of the modern synthetics, plus the rope color that many
people like. It is rot proof, water proof and not damaged by oil, gasoline
or most chemicals. In addition, it floats on the surface of water.
