Question

1. What are the two types of fibres on a sheep's coat?
2. What are the various features that make wool different from each other?
3. Define the following: a. Scouring b. Filature c. Sericulture
4. What is sorter's disease? Why were people working in wool industry prone to it?​

Answer 1

Explanation:

1. the hairy skin of the sheep has two types of fibres that form its fleece: (i) the coarse beard hair, and (ii) the fine soft under-hair close to the skin. The fine hair provide the fibres for making wool. Some breeds of sheep possess only fine under-hair.

2. Heat Conductivity: As wool fibers are non-conducts of heat, they permit the body to retain its normal temperature. Wool fabrics have built-in climate control. Wool is a natural insulator and keeps the bodywarm in winter and naturally breathable to keep the body cool in summer.

3. a) Scouring is the process of preparing and washing a batch of raw sheep's wool to remove impurities such as grease, dirt and suint.

b)a place where silk is obtained from silkworm cocoons.

c) Cultivation of silk is known as sericulture.

4.Sorter's disease (blood disease) is an example of an occupational hazard that is caused by the infection of a bacterium called anthrax. People working in the wool industry are prone to this disease.
