[1] Cottonization removes impurities (non-fibrous materials such as lignin or pectin) and shortens the fiber length of flax for subsequent spinning processes.
[1][2][3] Cottonization can convert flax to short single fibres.
These short fibres can be spun similarly to cotton.
It includes the process of removing the lignin that holds the hemp fibres together.
Lignin gives stalks their rigidity, It acts as a glue that holds the plant cell wall together.
