How are long fibres harvested and processed
Long fibres, also known as bast fibres, are harvested from the bark of certain plants and trees. The process of harvesting involves removing the outer layer of the plant, usually by breaking or crushing the stem. Once the outer layer has been removed, the fibres are separated from the inner core of the plant.
The process of separating the fibres can vary depending on the type of plant being harvested. Some plants, such as flax and hemp, require a soaking and drying process to help break down the outer layer and separate the fibres. Other plants, such as bamboo and jute, require a retting process where the stems are soaked in water to allow bacteria to break down the outer layer.
- Flax: After being harvested, the flax stems are dried and then soaked in water for several days to soften the bark. The softened bark is then removed and the fine fibres are combed out.
- Hemp: The hemp fibres are separated from the stem by a process called decortication. The stems are crushed and hammered to loosen the fibres, which are then separated from the woody core.
- Bamboo: The bamboo stems are cut and soaked in water for several weeks to allow bacteria to break down the bark. The fibres are then combed out and spun into yarn.
Once the fibres have been separated, they are cleaned and prepared for processing. This typically involves removing any remaining plant material, such as leaves or debris, and washing the fibres to remove any impurities.
The finished fibres can then be used in a variety of products including textiles, ropes, and paper.
| Plant | Harvesting Method | Processing Method |
|---|---|---|
| Flax | Dried and soaked in water | Bark is removed and fibres are combed out |
| Hemp | Crushed and hammered | Fibres are separated from the woody core |
| Bamboo | Soaked in water | Fibres are combed out and spun into yarn |
Overall, the process of harvesting and processing long fibres can be time-consuming and labor-intensive. However, the resulting fibres are often strong, durable, and natural, making them a popular choice for a variety of products.
