A rope is a group of yarns, plies, fibres, or strands that are twisted or braided together into a larger and stronger form. Ropes have tensile strength and so can be used for dragging and lifting. A rope is thicker and stronger than a similarly constructed cord, string, and twine. Common natural fibres for rope are manila hemp, hemp, linen, cotton, coir, jute, straw, and sisal. Synthetic fibres in use for rope-making include polypropylene and nylon. Packaging ropes are designed to seal boxes, containers and many other things. Browse through this category for a variety of packaging ropes available in Zambian stores.
The rope can be easily spotted – even against the dark backdrop of water – and can be used for rescue lines, mooring and towing, directing and guiding boats, and marking out specific areas in the water. Despite their strength and resilience, polypropylene ropes are relatively lightweight.
Polypropylene ropes are synthetic and possess a variety of unique qualities. Polypropylene rope is particularly suited for use around water and will not rot due to water and is resistant to mildew.
Synthetic fibres in use for rope-making include polypropylene, nylon, polyesters (e.g. PET, LCP, Vectran), polyethylene (e.g. Dyneema and Spectra), Aramids (e.g. Twaron, Technora and Kevlar) and acrylics (e.g. Dralon). Some ropes are constructed of mixtures of several fibres or use co-polymer fibres.
Polypropylene is a hardy polymer which is resistant to many types of glue and solvents. The rope is woven from three-strand yarn making it extremely durable and strong. Polypropylene also has a higher melting point than most common polymers, making it resistant to heat and friction.
Metal wire twisted in a plait construction to create a rope. Typically made from steel and can be coated in nylon.
Also known as parachute cord. Lightweight nylon cord with an inner core protected by a woven outer sheath.
Now most marine ropes are made of synthetic fibers like polyester, nylon, and polypropylene for both land and underwater purposes.
Nylon is low-friction, more malleable, and can withstand higher temperatures, making it ideal for prototyping and manufacturing components that will be subject to resistance.
Polypropylene is stronger than nylon and more resistant to physical stress, making it ideal for high-resistance equipment.
Nylon webbing is much stronger than polypropylene webbing. Nylon webbing has a tensile strength of 4,200 to 5,500 pound per 1-inch width, while polypropylene only has a tensile strength of 600 pounds per inch. Nylon webbing is also very durable. Nylon will be able to withstand a lot of abrasion.
Polyester rope wears better than polypropylene, is almost as strong as Nylon, and retains its strength when wet. It does not stretch as much as Nylon and does not float. It's the most abrasion-resistant of the synthetic rope types, and high abrasion resistance is very important if you want a long-lasting rope.
It is made with high quality components creating a smooth and soft-to-the-touch surface. Ideal rope for working with animals and you can take it to the water because polypropylene is buoyant and will float in water.
Many users ask “What is HMPE/Dyneema ® and Dyneema ropes”? The short answer is that Dyneema ® is the world's strongest man-made fibre™. Dyneema ® is also called ultra-high molecular weight polyethylene (UHMWPE), used for manufacturing several types of ropes, slings and tethers.
