what is processing of silk​

Answer 1

$\large\underline\mathsf\blue{Processing\:of\:Silk\::}$

　　　　　　　　　　　 

Processing of silk involves various steps :

　　　　　　　　　　　 

Step 1. Boiling :

　　　　　　　　　　　 

• The cocoons are first boiled in hot water or treated in ovens to kill larvae inside. If the larvae are not killed and allowed to grow.

• They will break the cocoon, thereby reducing the length of silk fibre. The hot water soften the silk gum, so as to allow unwinding of silk fibre as one continuous thread.

　　　　　　　　　　　 

Step 2. Reeling :

　　　　　　　　　　　 

• The process of taking out threads from the cocoon for use as silk is called reeling the silk.

• Reeling is done with special machines which unwind the threads or fibres of silk from the cocoon.

　　　　　　　　　　　 

Step 3. Throwing :

　　　　　　　　　　　 

• This process is similar to spinning of cotton. The raw silk is twisted to produce thrown silk.

• This process is called throwing revents the silk from splitting into individual fibres.

　　　　　　　　　　　 

Step 4. Dyeing :

　　　　　　　　　　　 

• Thrown silk is then dyed for making coloured fabrics.

• The dyed silk fibres are then spun into silk threads which are woven into by weavers.
