Ans: Processing Silk: Extracting silk from the cocoon is called processing silk. The processing of silk from cocoons follows - Step1: Separation of the silk fibre from the cocoon. For this, it is need to be exposed to warmth. Piles of cocoons are kept under the sun, boiled or exposed to steam. The warmth causes the silk fibre to separate from the rest of the cocoon. Step2: Reeling the silk, which is the process of delicately unwinding the fibre from the cocoon. Reeling is also done in special machines. Step3: The silk thread is then bleached and dyed into many shades. Step4: The silk fibre is then spun into silk thread, which is then woven into silk cloth by weavers.
