Question

describe the process of obtaining silk from cocon

Answer 1

Cocoons are treated with steam or boiling water , and each cocoon is unwound . Anywhere between four to eight cocoons are processed simultaneously to create a single strand of silk thread .

Raw silk contains sericin , a substance washed out before the fibers are made into fabric . It takes about 2,500 silkworms to make 1 pound of raw silk .
Four types of silk threads are produced from the raw fibres , such as crepe , tram , thrown singles , and organize . Crepe silk is produced by twisting two or more threads of silk together in multiple directions . Tram is made by twisting threads of silk in just one way . Thrown singles include just one silk thread twisted in a single direction , and organize is made of two or three threads twisted in one direction before twisting in one direction before twisting in the opposite direction .

Leftover silk is spun into yarn and sold as spun silk . These fibres have lower quality than reeled silk , and spun silk yarn is much cheaper . Combed silk is also sold as a leftover of the reeling process .
