A) Rearing B) Sorting C) Scouring D) Reeling

Answer 1

The process of taking out silk threads from the cocoon is known as Option D) reeling.

There are three steps to the process of silk reeling:

1. Stifling process

• It is the step to be carried out before reeling.
• It is the process of killing the pupae in the cocoon by the way of  steaming process.
• The sifting is undertaken with utmost care in order to save the silk quality.

2. Cocooning

• The cocoon is boiled in a hot water bath to soften and dissolve the shell which is full of sericin gum.

3. Silk reeling

• In this last step, two silk filaments are attached to each other to form a bave (also known as bifilar thread) and bave is unwounded.

Silk fibers are spun to the thread by using reeling devices.

Answer 2

Answer:

Option D) Reeling is the correct option. Reeling is the process of taking out thread from the cocoon for the use of silk.

Explanation:

Reeling is the process that is carried out by special machines like conveyor type of machine or now used automatic reeling machine.

These machines are used to unwind the silk fibers or the threads from the cocoon.

• First, a group of cocoons is cooked in a hot water bath and their filaments are unwinded collectively at one end and on the other end, the filaments or threads are winded on a moving reel.

• Silk fibers are then transformed into silk threads used in making silk fabrics like silk sarees etc.
• Rearing of the silkworm is the process that is used for obtaining silk. It is also called sericulture.
• Sorting- It is the process that sorts out the defective cocoons by using a cocoon sorting table in a dark room.
• Scouring- It is the process that removes dirt, oils, fats & sericin, as well as coloring matters, and mainly the gum that envelops the silk yarn.
