Question

1)describe the texture of silk fibre obtained from Mulberry Silk moth
2)What is reeling of silk
3)Explain the process of obtaining silk from cocoon

(give answer of all question with a proper number)​

Answer 1

Answer:

1. The silk fibre from the cocoon of this moth is soft, lustrous, and elastic and can be dyed in beautiful colours.
2. Silk reeling is the process by which a number of cocoon baves are reeled together to produce a single thread. This is achieved by unwinding filaments collectively from a group of cooked cocoons at one end in a warm water bath and winding the resultant thread onto a fast moving reel.
3. In order to obtain silk, mulberry trees are cultivated, silkworms are reared and their cocoons are collected to get silk fibres. The various steps involved are:

(i) Rearing of silkworms: A female silk moth lays hundreds of eggs at a time.

(ii) Processing of cocoons to obtain silk fibres: The pile of cocoons is placed in hot water. Hot water makes the silk fibres of cocoons to separate out. The long fibres are obtained by unwinding the threads from cocoons. This process is called reeling.

(iii) Converting silk fibres into silk cloth: Silk fibres obtained from cocoons are spun (twisted) to form silk threads called silk yarn. The silk yarn is then woven on looms into silk cloth by the weavers.
