Fiber crop

Fiber crops are field crops grown for their fibers, which are used to make paper, cloth, or rope. These crops are generally harvestable after a single growing season, as distinct from trees, which are typically grown for many years before being harvested for wood pulp fiber. In specific circumstances, fiber crops can be superior to wood pulp fiber in terms of technical performance, environmental impact or cost.

There are a number of issues regarding the use of fiber crops to make pulp. One of these is seasonal availability. While trees can be harvested continuously, many field crops are harvested once during the year and must be stored such that the crop doesn't rot over a period of many months. Considering that many pulp mills require several thousand tonnes of fiber source per day, storage of the fiber source can be a major issue.

Botanically, the fibers havested from many of these plants are bast fibers; the fibers come from the phloem tissue of the plant. The other fiber crop fibers are seed padding, leaf fiber, or other parts of the plant.

Fiber crops include:

• Bast fibers (Stem-skin fibres)
  • Jute (widely used, cheapest fibre after cotton)
  • Flax (which produces linen)
  • Ramie
  • Hemp
  • Kenaf
  • Abacá
  • Nettles
• Other fibers (Leaf, fruit, and other fibers)
  • Cotton
  • Bamboo fiber
  • Esparto
  • Papaya
  • Umbrella plant
  • Coir (fiber from the coconut shell)
  • Sisal (Often termed agave)
