Question

The process of taking out threads from cocoon is known as:
A. Rearing
B. Sorting
C. Scouring
D. Reeling

Answer 1

Hint: The way toward getting crude silk by loosening up the strings from covers. The arranged cases that are to be reeled are steamed to mollify the sericin establishing the strings, after which the finishes of the strings are found.

Complete step by step answer:
Silk reeling is the cycle by which various case baves are reeled together to create a solitary string. This is accomplished by loosening up fibers on the whole from a gathering of cooked covers toward one side in a warm water shower and winding the resultant string onto a quick moving reel. Crude silk reeling might be grouped by direct reeling technique on a standard measured reel, circuitous strategy for reeling on little reels, and the exchange of reeled silk from little reels onto standard estimated reels on a re-reeling machine. The last method is basically applied in present day silk reeling measures.

Various silk reeling gadgets
1. Hand turning wheel
This crude turning mechanical assembly is worked by two hands – one to drive the haggle other to take care of in cases. One finish of the reeling string is wound onto each wheel, while casings are bubbled in a different pot.
2. Charkha type reeling machine
The Charkha type is being used in India. This machine is worked with discrete work movements in reel driving and casing taking care of to reeling closes by two men for each machine. Each machine has 3 finishes or more to a reel, which is a similar size as the huge wheel of the Re-pulling machine so as to spare the re-reeling measure (direct reeling technique).
3. Sitting sort reeling machine
There are two sorts of sitting kind reeling machines, foot worked and engine driven. The engine driven reeling machine isn't furnished with the stop movement connection . There are obstructions to the creation of good quality crude silk as the crude silk string is twisted also quickly to keep up great quality control.

So, The correct option is D. Reeling

Note:
The larvae after maturation crawl down the tree at dusk, which are then handpicked and placed in “Jali” (cocoonage) for spinning of cocoons. For continuation of generations 5% seeds cocoons are selected and kept in the grainage hall for emergence of moth and production of eggs.
