Carbonization of wool?

Carbonization of wool is a process of removing vegetable matter and other impurities from raw wool. This process involves treating the wool with sulfuric acid, which dissolves the impurities and leaves behind a purified form of wool.
The process of carbonization involves soaking the wool in a dilute sulfuric acid solution, which breaks down the vegetable matter and other impurities. The wool is then washed thoroughly to remove any remaining acid and impurities. The end result is a purified wool fiber that is free from any unwanted materials.
Carbonization of wool is used primarily in the production of high-quality woolen fabrics, where a clean and uniform fiber is required. It is also used in the production of wool for use in spinning and weaving, where impurities can cause problems with the quality of the final product. However, carbonization can also weaken the wool fiber and reduce its strength, so it is not suitable for all types of wool.
