3. HISTORY
China is the birth place of silk . It was found almost about 6,000 years
ago. According to the legend once a lady His-Lin-Shih (she is a
queen) was having tea under a mulberry tree when a cocoon fell in
her tea. While she was opening the cocoon, she realized that the
cocoon could be used as a weaving thread. Thus a industry was
born. She taught people how to raise silkworms and later invented
the loom. Silk was produced at a large scale during the Shang
Dynasty (1600BC-1046BC)
Silk was kept a secret for more than 200 years by the Chinese. It was
a very zealously guarded secret in history. Anyone found guilty for
smuggling was put to death. It was worn by the extremely Upper
class. Sericulture began to reach outside world first Korea then Japan
, India and finally Europe.

4. CHARACTERISTICS
• It is very versatile , lustrous and comfortable.
• It absorbs moisture.
• It is cool to wear in summer and warm to wear in winter.
• It can be easily dried.
• It is very smooth and retains its shape
• It has poor resistance to sunlight exposure.
• It is the strongest natural fiber

5. USE

6. PROCESSING
Cultivation of silkworm is known as sericulture. The main type of silk
is obtained from Bombyx mori (a type of silk worm).Silk worms hatch
up to 3 times a year . The major producers of silk are
• first China
• Second India
• Third Uzbekistan
Cocoons are first collected .Then they are sorted based on color ,
size , shape and texture. Then they are dipped in water so that the
filament can be extracted . Then they are unwined . Then they are
Reeled with the help of a yarn . Then the strands are twisted and are
put through rollers. Yarns are washed with soap to make them shine .
Them they are pulled to enhance their luster . Then they are made
smooth. Then their wrinkles are removed by pressing. And then they
are weighed and send for weaving.

7. ADVANTAGES
