Quick Answer
Milkweed is not as good as hemp for survival uses, specifically when it comes to making cordage and textiles. While milkweed fibers can be used for crafting, they are typically not as strong or durable as hemp fibers. This is due to the differences in fiber length and tensile strength.
Hemp vs Milkweed Fiber Length
Hemp fibers can reach lengths of up to 10 feet (3 meters), making them ideal for creating strong, durable cordage and textiles. In contrast, milkweed fibers are generally shorter, typically ranging from 1-3 inches (2.5-7.5 cm) in length. This shorter length makes milkweed fibers more difficult to work with and less suitable for survival applications.
Tensile Strength Comparison
The tensile strength of hemp fibers is significantly higher than that of milkweed fibers. Hemp fibers can withstand tensile forces of up to 450 pounds per square inch (psi), while milkweed fibers typically have a maximum tensile strength of around 50 psi. This strength difference is critical when it comes to creating reliable cordage and textiles for survival uses, such as building shelters or securing gear.
Alternative Uses for Milkweed
While milkweed may not be as suitable for making cordage and textiles, it does have other survival uses. The plant’s sap can be used as a natural adhesive, and its seeds can be roasted and eaten as a food source. Additionally, milkweed’s tall stalks can be used as a natural support or stake for shelter construction. However, it is essential to note that milkweed is also the host plant for the monarch butterfly, and its use should be carefully considered to avoid harming the ecosystem.
