Bamboo staple fibre is produced mechanically via a retting process, similar to flax production. The woody bamboo stems are crushed and natural enzymes break down the stems so the fibres can be combed out and spun. This is a very labour intensive process.
I have spun bamboo staple fibre before and the fibers were quite long and easy to spin in a worsted spinning style. For this particular batch of bamboo fibre, the fibers are quite short and feel much like cotton. So I decided to use a cotton spinning method. I carded some of the fibre on my drum carder and rolled it into small rolags.
