How much is polyester rope stretched in comparison to its original length?

Polyester rope is known for its strength and low stretch characteristics. When under load, polyester rope generally stretches up to one-third of its original length. This means that if you have a polyester rope that is 100 feet long, it could stretch up to approximately 33 feet when under significant load. This property is crucial to understand because it affects how the rope performs in various applications, particularly in marine contexts where predictable performance and reliability are essential for safety and operational effectiveness. This stretch is less than many other types of fibers, making polyester a preferred choice for applications where low elasticity is an advantage.
