Sisal and hemp are both natural fibers that are used to make twine and other textiles. These fibers come from different plants and have some unique characteristics.
Sisal comes from the leaves of the Agave sisalina plant. The origin of the plant is uncertain, but it has been grown commercially since the 1930s.
Hemp fiber comes from the stalk of the Cannabis sativa plant, which is a cousin to the marijuana plant. Hemp has been grown in China to make twine and textiles for 6,000 years.
Sisal is especially useful as a twine because it has the ability to stretch, is durable and resists deterioration even in salt water.
Hemp is one of the strongest natural fibers, so twine made from hemp is extremely durable and is mildew resistant.
The sisal and hemp fibers used to make twine are coarse and rough, but both of these fibers are also used to make cloth that is softer and more luxurious than cotton.
