Quick Answer
Improperly retted dogbane fiber can lead to weak or brittle cordage, reduced durability, and increased risk of breakage under load. This can result in lost gear, compromised shelter, or even put the user at risk. Inadequate retting can also lead to skin irritation or allergic reactions.
Poor Retting Process Risks
Improper retting of dogbane fiber is a common mistake that can have significant consequences. Dogbane (Apocynum cannabinum) contains saponins, which can cause skin irritation if not properly removed through the retting process. If the fiber is not fully retted, these saponins can still be present, leading to skin reactions, eye irritation, or even allergic responses in some individuals.
Weak or Brittle Cordage
If dogbane fiber is not properly retted, it can become weak or brittle. This is because the fibers may not have been fully broken down, resulting in a cordage that is prone to breakage. When making cordage, a minimum of 2-3% moisture content is recommended to achieve optimal strength. If the fiber is too dry, it will be brittle and prone to cracking. Conversely, if the fiber is too wet, it will be weak and prone to breakage.
Retting Techniques
To properly ret dogbane fiber, it’s essential to use the right techniques. The simplest method is to submerge the cut dogbane stalks in water for 7-10 days, changing the water every 2-3 days. This process allows the saponins to break down, releasing the fibrous material. The resulting fiber can then be removed, washed, and dried to create strong, durable cordage.
