Is it possible to identify the best bark fiber by touch?

Identifying Bark Fiber by Touch

When examining bark fibers by touch, look for fibers that have a smooth, even texture, and are flexible to the point of being able to bend without breaking. A good bark fiber should be able to withstand some tension without snapping, but not be too stiff or brittle. Measure the diameter of the fibers with your fingertips; those around 0.5-1.5 mm in diameter are generally ideal for cordage.

Key Characteristics of Good Bark Fibers

Good bark fibers should have a natural wax coating, which helps them repel moisture and resist rot. Check the fibers for any signs of excessive moisture or mold growth, as these can indicate poor quality. A good bark fiber will also have a slight sheen, indicating its natural wax coating. When examining the fibers in different lighting conditions, look for any changes in color or texture that could indicate poor quality.

Testing Bark Fiber Flexibility

To test the flexibility of the bark fibers, bend them sharply back and forth several times. A good bark fiber will be able to withstand this without breaking or showing excessive wear. Measure the fibers’ strength by testing their resistance to tension; a good bark fiber should be able to withstand a certain amount of tension before snapping. For example, a good oak bark fiber should be able to withstand around 10-15 kg of tension without breaking.
