There are two process charts given below. One of these reveals information about the lifecycle of the silkworm which is continuous process, and the second one illustrates the production of silk cloth. Overall, the whole process is composed of different stages.
Starting with the first diagram, the silkworm lays a number of eggs on mulberry leaves. The budding embryos inside the fertilized eggs take ten days to form silkworm larva. These larvae keep feeding on mulberry leaves during their evolution, and they keep encapsulating by secreting silk threads, for four to six weeks. It takes three to eight days more to form a complete encapsulated structure called a cocoon. The larva inside the cocoon develops further giving rise to a mature moth after sixteen days.
Heading towards the second diagram, which describes six stages of silk cloth production that initiate with the first step of selection of healthy cocoons. In the second step, these cocoons are boiled in a container vigorously. The larva inside the cocoon dies, and the cocoon is unwound giving around 300 to 900m of thread. Afterwards, the thread is twisted to enhance its strength before dyeing it. The twisted thread can also directly be subjected to weaving without dyeing, and the final cloth obtained can be sent for dyeing.
