Producing silk is a lengthy process and demands constant close attention. To produce high quality silk, there are two conditions which need to be fulfilled: preventing the moth from hatching out and perfecting the diet on which the silkworms should feed. Chinese developed secret ways for both.

Stage 1:

The eggs must be kept at 65 degrees F, increasing gradually to 77 degrees at which point they hatch. After the eggs hatch, the baby worms feed day and night every half hour on fresh, hand-picked and chopped mulberry leaves until they are very fat. Also a fixed temperature has to be maintained throughout. Thousands of feeding worms are kept on trays that are stacked one on top of another. A roomful of munching worms sounds like heavy rain falling on the roof. The newly hatched silkworm multiplies its weight 10,000 times within a month, changing colour and shedding its whitish-grey skin several times. A silkworm's life spans only 25-28 days.

Stage 2:

The silkworms feed until they have stored up enough energy to enter the cocoon stage. While they are growing they have to be protected from loud noises, drafts, strong smells such as those of fish and meat and even the odour of sweat. When it is time to build their cocoons, the worms produce a jelly-like substance in their silk glands, which hardens when it comes into contact with air. Silkworms spend three or four days spinning a cocoon around them until they look like puffy, white balls.

Stage 3:

After eight or nine days in a warm, dry place the cocoons are ready to be unwound. First they are steamed and then dipped into hot water to loosen the tightly woven filaments. These filaments are unwound onto a spool. Each cocoon is made up of a filament between 600 and 900 metres long! Between five and eight of these super-fine filaments are twisted together to make one thread.

Stage 4:

Finally the silk threads are woven into cloth or used for embroidery work. Clothes made from silk are not only beautiful and lightweight; they are also warm in cool weather and cool in hot weather.
