About Rope and Twine - General Information Terms: • Rope: Rope is a general term applied to a length of fibers that are twisted or braided together in one of a number of patterns to provide lifting or pulling strength. Rope may be manufactured of natural or synthetic fibers to produce specific handling and strength characteristics.

• Twine: Twine is a light duty type of rope.

• Cord: Cord is another name for small diameter rope. Materials: • Nylon: Synthetic material offering good strength and very good abrasion resistance. Resists hydrocarbon.

• Cotton: Natural fiber has low strength. Holds up well in Alkalis, poorly in hydrocarbon.

• Polyester: Synthetic fiber with good strength, long life, and good resistance to acids and hydrocarbons.

• Polypropylene: Synthetic fiber with moderate strength. Resists acids, alkalis, and hydrocarbons and it floats. Configurations: • Twisted: Fibers are turned and lock stitched together. Twisted twine holds knots well but tends to unravel. Moderate strength. Rotates under load.

• Diamond Braid: Strands are braided over and under each other in a circular direction and may have a separate core. Lower strength. Does not rotate under load.

• Solid Braid: The fibers are braided solid to the core to produce a smooth surface, which stays flexible and knots easily. Lower strength moderate flexibility and excellent abrasion resistance. Does not rotate under load.

• Hollow Braid: Strands are braided over and under each other in a circular direction without a separate core. High strength and flexibility. Does not rotate under load.
