Question

Woollen clothes are prepared from:
(A) Wool worms
(B) Carbon compounds
(C) Fleece of sheep
(D) Cotton plants

Answer 1

Wool is the natural source of the fabric in nature which means that this is either obtained from the plants or animals in general. Woollen clothes are the basic requirements by humans during winters on a large scale.

Complete answer:
Let us learn about the wool and its properties.
Wool-
It is the textile fibre obtained mainly from sheep. Chemically, wool consists of protein with small percentages of lipids which makes it different from the dominant textile i.e. cotton which is mainly cellulose.
Process-
Sheep shearing is the prime most step while preparation on woollen clothes from wool. In this process, the woollen fleece of the sheep is cut off during summer times.
The straight cut off wool contains some impurities such as dead skin of sheep, sweat residue, etc. So, before we use wool for commercial purposes, we need to clean it. Hence, scouring (cleaning the greasy wool) is done.
Thus, then the wool obtained is spun and made into woollen clothes to keep us warm.
Hence, by this process and description we can see that, the sheep has soft and woolly coats known as fleece which after processing turns out to be woollen clothes.

Therefore, option (C) is correct.

Note:
Do note that, when we think of wool, we would only concentrate towards sheep but this is not the actual fact. Various animals such as camels, goats and rabbits also produce hair (fine protein fibre) which can be classified as wool.
