Processing of Wool

Wool is a fibre obtained mainly from sheep

Sheep hair has two types of fibres

1. Rough beard hair2. Fine under hair.

Fine under hair provides the fibre to make wool.

The process of making fibre into wool follows a series of steps.

They are shearing, scouring, sorting, dyeing, straightening, rolling and combing

1. Shaving off the hair of sheep along with a thin layer of skin is called shearing.

It is done by machines, mostly in the hot season when the sheep do not require the outer skin to keep warm.

2. The sheared skin with hair is then washed.

Washing removes dust, dirt by a process known as scouring. It is done in machines.

The machines use hot water and detergents to remove grease, sweat, dirt, thus leaving behind the clean wool

3. The washed hair is separated according to the texture and type.

This process of separating different types of hair is called sorting. This is mostly done with hands.

The good quality fibres are used for clothes and lower quality is used for making rugs

The sorted fibres are then washed separately so that only clean fibres are processed further.

4. Fibres can then be dyed in various colours.

The natural fibre is white, black or brown, but they can be dyed in beautiful colours.

5. Finally, the fibres are straightened, combed and rolled into yarns.

The longer fibres are made into wool for sweaters and the shorter fibres are spun and woven into woollen clothes.

Revision

Wool is a natural animal fibre made from sheep hair.

Wool is used for making warm clothes i.e. sweater, shawls etc.

Processing of wool undergoes many steps from raw fibre to finished wool

In the shredding process the sheep hair is shredded and cleaning process is done to remove dust

After that the clean fibre is sorted and dyed into different colours

Lastly the fibre is straightened, rolled and combed in automatic machines

Now the furnished wool is ready to use in production of sweaters, shawls, and many warm clothes
