Yarn production in general involves a series of processes. After harvesting, retting and drying, the successive steps are breaking and scutching (§7§7.1.1), possibly softening (§7§7.1.2), hackling (§7§7.1.3), preparation for spinning (§7§7.1.4) and finally spinning (§7§7.1.5, 7.2).
The Figure below shows a schematic overview of the main processing steps (dark blue/dark grey) and the resulting (intermediate) products (light blue/light grey), starting with the hemp straw that is harvested. This diagram also shows how many kg of product are usually indicatively obtained during each step.
