Wool is an important textile fiber. It is a protein fiber; it contains some special protein like keratin. Keratin is the main chemical composition of wool. It is important to know the physical and chemical properties of wool.
Chemical Composition of Wool Fiber:
The following is the chemical composition of wool. They are-
- Keratin: 33%
- Grease: 28%
- Suint: 12%
- Different Impurities: 26%
- Mineral Water: 01%
The keratin of wool is a protein of empirical formula. The exact composition depends upon the position of the material in the fiber and the treatment to which it has been subjected. Keratin contains sulpher for this reason it is very easy to separate keratin from the other elements.
Chemical Composition of Keratin:
The following is the chemical composition of keratin. They are-
- Carbon: 50%
- Hydrogen: 12%
- Oxygen: 10%
- Nitrogen: 25%
- Sulpher: 3%
Different fibers have different chemical compositions. So, we should know the element’s name and its quantity in the composition.
