A method for manufacturing a yarn from a paper mulberry tree is provided to produce a natural fiber having a characteristic of a vegetable fiber such as excellent air permeability and hygroscopicity and a characteristic of a synthetic fiber such as excellent elasticity and durability. A paper mulberry tree is steamed or boiled to obtain the bark of the tree. White bark is produced by removing the outer bark from the obtained bark and drying the bark of which the outer back is removed. The white bark is boiled in alkaline water. The boiled white bark is torn into thin white bark strands. A long bark strand is formed by connecting end portions of the thin white bark strand. A tanning process is performed on the long bark strand. |
