Wool is the soft curly covering which forms the fleecy cost of the sheep and similar animals.

Wool was no doubt the first fibre used by man as clothing. It was worn first in the form of a skin or pelt; later the fibres were matted or felted to make a fabric. The next step in its development was the formation of the fibres into yarns from which fibres were constructed. Today the pelts of certain sheep are used as furs while the loose fibres from other pelts are felted to form the felt or are twisted into wool yarns to be woven, or knitted into every type and variety of material.

Sheep are raised where extensive pastures are available, and where the climate permits them to winter in the open. The principal sheep-breeding regions are Soviet Union (Georgia, Moldova, Kazakhstan, Kirgizien), Australia, New Zealand, South America, North America and South Africa.

The sheep are sheared to get the wool. The sheared wool is a dense mass of fibres, forming the so-called wool fleece. The fleece to be spun into yarn must be sorted and then washed several times to remove dirt and fat.

Wool fibres are soft and very elastic. Due to the high elasticity of the fibres, woolen textiles hardly crease and retain shape. Wool fibres are poor conductors of heat, that is, they retain heat. Wool fibres are sensitive to heat. Therefore, woolen textiles are not as great as that of flax and cotton.

1. Cotton is the most important vegetable fibres used in the textile industry.

2. The cotton fibre is a soft substance growing around the cotton seeds. When the seeds are ripening their fibres spring out of the burst boll and are picked manually or mechanically. Having been picked$ cotton is mechanically cleaned and separated from the seeds, and then, subjected to further treatment.

3. The ease with which cotton fibre can be transformed into yarn and its suitability for all forms of woven and knitted fabrics, together with its cheapness of production, have caused it to take the leading place among textiles.

4. The cotton plant is usually grown as an annual and requires a warm climate. The leading cotton-cultivating countries are the Uzbekistan, the South of the USA, India, Pakistan, the South-American countries, Egypt and China.

5. The strength of cotton fibres is relatively high compared with their fineness and it further increases when wet.

Cotton fibres are not very elastic, that is why cotton fabrics crease easily. Absorbing moisture well cotton fibres can be easily dyed; as cotton fibres are good conductors of hest, cotton textiles have a cooling effect in hot weather.
