Answer 2

Answer:

1. Sericulture

This is the term used to describe the process of gathering the silkworms and harvesting the cocoon to collect the materials.

Female silkmoths lay anything from around 300 – 500 eggs at any one time. These eggs eventually hatch to form silkworms, which are incubated in a controlled environment until they hatch into larvae (caterpillars).

The silkworms feed continually on a huge amount of mulberry leaves to encourage growth. It takes around 6 weeks to grow to their full potential (about 3 inches). At this time, they’ll stop eating and begin to raise their heads – that’s when they’re ready to spin their cocoon.

2. Thread extraction

Once the silkworms have spun their cocoon, they will eventually enclose themselves inside it and then it’s time to extract the silk threads.

The cocoons are placed into boiling water in order to soften and dissolve the gum that is holding the cocoon together. This is a crucial step in the silk production process as it ensures that there is no damage to the continuity of each thread.

3. Dyeing

When the silk threads have been washed and degummed, they will be bleached and dried before the dyeing process commences.

Traditional silk dyeing techniques take the dyes from natural resources found in the surrounding environment, such as fruit or indigo plant leaves. The threads will be soaked together in bundles, inside a pot of hot indigo leaves and water. This process will occur multiple times over a span of days to ensure proper colour tone and quality.

However, these traditional dyeing methods have almost become extinct in the commercial manufacturing of silk. Advances in technology mean that manufacturers instead opt for using various dyes such as acid dyes or reactive dyes. This gives a greater range of choice in colours and shades to be able to serve wider demand.

4. Spinning

The traditional spinning wheel has always, and will always be an integral part of the silk production process. Although updated industrial processes are now able to spin silk threads much quicker, it simply mimics the functions of the classic spinning wheel.

The process of spinning essentially unwinds the dyed fibres on to a bobbin, so that they lay flat ready for the weaving process. This can be done in many different ways from hand-spinning to ring-spinning and mule spinning.

5. Weaving

Weaving is the process in which the final piece of silk comes together. There are many different ways in which silk can be woven – satin weave, plain weave and open weave are most common, and the finish of the silk will depend on the type of weave.

6.Printing

Should a piece of silk require a special pattern or design, it will need to be printed after pre-treatment. This can be done in two different ways: Digital Printing or Screen Printing.

Digital silk printing uses a specially designed textile printer, using ink to transfer hand drawn or digitally produced artwork on to fabrics.

7. Finishing

In order to be deemed ready for use, silks must be finished. Finishing a piece of silk gives it that highly lustrous sheen that it is so commonly known for, and is the reason that the desired look and feel can be achieved.

Silk finishing can be done in many different ways, mainly by applying different chemical treatments which can add a host of valuable properties including fire resistance and crease-proofing.
