Which natural fiber is commonly used as a natural fiber grade?

• A. Hemp
• B. Jute
• C. Sisal
• D. Manilla

Answer: (D)

In choosing a natural-fiber rope grade, Manila fiber is the standard because it offers a superior balance of strength, flexibility, and wear resistance. Manila rope, made from abaca fibers, has long, strong filaments that deliver high tensile strength for its size, yet remains more pliable than some other natural fibers. It handles knots and bending without excessive fraying, and holds up well under abrasion, which makes it reliable for rigging and general use where a natural-fiber grade is expected. Hemp is a strong natural fiber, but it tends to be coarser and isn’t as commonly used to define the standard natural-fiber rope grade. Jute and sisal are widely used for cheaper or lighter-duty applications, but they generally offer lower tensile strength and poorer moisture stability, making them less suitable as the representative natural-fiber grade.
