Question

Describe the process of extracting wool with relevant diagramd

Answer 1

$\huge\mathfrak\red{Answer}$

Step I:     The first step is the removal of the fleece of the sheep along with a thin layer of skin. This process is termed as shearing. The hair provides woollen fibres that are then processed to obtain woollen yarn.

Step II:     The sheared fleece is systematically washed in tanks in order to remove the grease, dust and dirt. This is known as scouring.

Step III:    The scoured hair is then sorted and sent to a factory where hair of different textures are separated or sorted.

Step IV:    Here the small fluffy fibres, called burrs, are separated from the hair and the hair is scoured again and dried. The wool is then ready to be drawn into fibres.

Step V:      The fibres are dyed into various vibrant colours because the natural colour of the fleece is black, brown or white.

Step VI:     The fibres are then straightened, combed and finally rolled into yarn. The longer fibres are made into wool for sweaters whereas the shorter fibres are spun and woven into woollen cloth.

Explanation:

Process of Extracting wool

The whole process starting from the shearing of the coat of sheep to wearing it into garments involves the following steps :-

1. Shearing : The process of removing fleece from the body of sheep is called shearing. The person who removes the wool is called a shearer. It is done manually with clippers or a pair of scissors. It is also done by using a shearing machine. Sheep are shorn generally once in a year, during the hot weather.

2. Scouring : The raw seared wool is throughly washed in tank to remove grease , dirt and dust. This process is called scouring. Now - a - day it is done by machines.

3. Sorting: After scouring, hair is sent to a factory where they are separated but according to their texture.

4. Carding : The wool fibers are combed into a carding machine into parallel rows of fiber, which is called slivers. The carding machines have wire toothed rollers to separate the wool into lose ropes of slivers.

5. Roving : A number of slivers are rolled into a thin rope is called roving which is used to spin yarn.

6. Dyeing : Next, the wool is dyed into various of colors depending on your requirement because the natural fleece is black, brown or white.

7. Spinning : After roving, the fibers are oiled, straitened, washed and twisted together to spun into yarn.

8. Weaving or Knitting : The shorter fibers are spun and woven into woolen clothes and the longer fibers are spun and knitted for making sweaters.

Since the 1800's, spinning and weaving have become increasingly mechanised and woollen cloth made entirely by hand has become a rare luxury.
