General Processing of  Bast Fibers

General Processing of  Leaf Fibers

General Processing of  Grass Fibers

 

All plants have cellulose fiber which is the ingredient to make paper but some plant fibers are too weak and other to strong and difficult to make paper pulp out of      
 The most common Japanese papermaking fiber. The inner bark of shoots of the Paper Mulberry plant (Kozo). These shoots are harvested annually therefore the material is replenishable.      Linters
Fiber cooked in lye before pressed into sheets.
Japanese Kozo
There are three bark layers in this plant:
  • black bark (chiri)
  • green bark
  • inner white layer

  • strong fiber an very long strands 
    cooked in mild caustic for preparation (soda ash) 
    hand beaten 
    too delicate for a Hollander beater. 
    Traditional sheet requires use of formation aid

    Thai Kozo = grown under different climate conditions

     
Philippine Gampi
The most refined Japanese papermaking fiber.  
Acts similar to Kozo in the vat but is a very different plant. 
Resulting paper has a silky sheen. 
Cook in soda ash. 
Do not beat in a Hollander. 
 requires use of formation aid.
Crisp, lustrous off white to tan insect resistant high resistant high shrinkage.
     
       

Misc. Notes

Half Stuff is partially prepared fiber, sometimes from cloth scraps
Wood fibers from soft and hardwood trees are possible
Fibers used in textile and basketmaking are often suitable (Raffia,Seagrass, Jute, Sisal)
Also: Linen, Milkweed. Iris, Okra
Recycled Material- can be made from waste paper of good quality
