ROPE CONSTRUCTION

SOLID BRAID:  A firm, round rope that works extremely well on blocks and pulleys.  Its name refers to the special lock-stitch construction of the rope.  Solid Braid rope does not unravel when cut, or accidentally broken, as much as other construction.  It is available in various synthetic and cotton fibers.  Reference fig. A.

HOLLOW or MAYPOLE BRAID:  This rope is constructed of 8,12, or 16 strands with a hollow center.  An outstanding characteristic of this construction is its ability to be spliced in just seconds.  It is available in various synthetic fibers.  Reference fig. B.

DOUBLE BRAID:  Also known as Braid-on-Braid, is actually two braided ropes combined into one rope.  A braided core is covered with a braided jacket to produce a strong, handsome, easy handling rope.  This rope is spliceable and, in most instances, stronger than twisted rope of the same material and diameter.  It is available in various synthetic fibers.  Reference fig. C.

DIAMOND BRAID:  Constructed with a tighter locking interlacing of yarns, normally using 8 or 16 strands.  This construction permits a core (inside) fibers to be used for the purpose of adding strength or a filler to produce a larger rope diameter.  Reference fig. D.

TWISTED: Also known as Laid Rope.  Just about all laid rope is 3-strand construction.  It is spliceable and is available in virtually every type of rope fiber.  This is the most common rope construction for general purpose use.  Reference fig. E.

PLAIT:  A rope where four sets, of two strands each, are intertwined in a maypole fashion around the rope axis in a plain pattern, one over and one under.  Reference fig. F.

RHINO KOTE™

Rhino Kote™ is a polyurethane coating applied to the line after braiding

Rhino Kote™ is a spliceable coating

Advantages:  Adds abrasion resistance.  Helps prevent snagging.  Helps protect core yarns from outside contaminations.  Color codes the line for visual identification.

Colors:  Black, Orange, Red, Yellow, Green, Blue, Clear

ROPE FIBERS & TYPES

COMBOS:  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.

COTTON:  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.

GOLD BRAID®:  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 ahs alternating white and gold yarns.

MANILA:  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.

NYLON:  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 than acids.

POLYESTER:  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.  

POLYETHYLENE:  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 construction.

POLYPROPYLENE (Poly):  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.

PRO*LINE:  A Wellington registered trade name for multifilament polypropylene rope.  Available in either solid or diamond braid and laid (twisted) construction.

SISAL:  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.

ULTRA HIGH MOLECULAR WEIGHT POLYETHYLENE (UHMWPE):  An extended chain polyethylene fiber characterized by a very high and narrow molecular weight distribution achieved by gel spinning of the polymer.

UNMANILA®:  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.
