Question

Wool is obtained from the fleece of
A) Goat
B) Sheep
C) Horse
D) Both A and B

Answer 1

Hint: Wool is a fully natural fibre stock. After shearing, animals develop a new fleece each year, which can be shorn the following year. Natural fabrics, such as fur, are $100$ percent biodegradable. Wool is a protein that occurs naturally and is identical to that found in human hair.

Complete answer:
Wool is obtained from the fleece of sheep.
The main source for yielding wool is sheep. The wool is derived from two forms of hair in most sheep. Kemp refers to the coarse outer fur. The true wool, which is obtained from the fine, soft undercoat close to the skin, is the fine, soft undercoat from which wool fibre is obtained.
Step by step extraction of wool from sheep –
Shearing – Shearing is the method of removing the woolen coat or fleece from an animal. Shearing instruments such as scissors, hand knives, and electric shears are used to do this without damaging the animal. Shearing is normally done in the summer when the weather is mild. By the time winter comes, they would have regrown their hair. One sheep can produce anywhere from $1$ to $3$ kg of wool.
Scouring – Raw or grease wool is wool that has been taken directly from the sheep. To remove grease, dust, and dirt, raw sheared wool is washed in tanks with detergent and alkali. This is referred to as scouring. It is now achieved by a computer.
Sorting and grading – Defective or inferior wool is removed after scouring. Sorting is the term for this procedure. Grading is the method of sorting wool based on the weight, color, and texture of the fibres.
Carding – Wool must be disentangled and washed until it can be used to make clothing. Carding is a method in which wood fibres are straightened by passing them through a series of metal teeth.
Making Yarn – Carded wool is twisted into a silver cord to make yarn. Silver is twisted and stretched into a thin thread. A mule spinning system is commonly used to spin woolen yarns.
Washing and finishing – Woolen yarn is spun or knitted into fabric, which is then used to produce finished goods like clothing, tablecloths, and bags.

Thus the correct answer is option ‘B’.

Note: Wool is a durable fibre that keeps its attractive look for a long time. Wool extracts moisture from the body and absorbs it within its fibres as a cloth. As the moisture is absorbed, heat is produced, keeping the garment warm without feeling damp.
