Need help on reviewing my IELTS essay The diagrams illustrates the life cycle of the silkworm and the procedures of silk cloth making. It takes 7 to 8 weeks from silkworm eggs to the yield of cocoon. Mature moth lay their eggs on mulberry leaves which is also the staple of silkworms. After 10 days of waiting, larva would hatch out of the eggs. During the next 4 to 6 weeks of their life cycle, certain secretion of the silkworm would wrap itself up, forming the cocoon which is the raw material of silk cloth. Part of the cocoons would be spared to grow into moths to continue their life cycle by laying eggs. The rest would then be chosen to heat in boil water. Each cocoon can be unwinded into 300-900m of thread. And every 3 threads would be twisted together before dyeing. Until this step, we are able to weave the threads into silk cloth. A second dyeing is in order to fortify the coloring. Given the nature of silk cloth, silk is considered as a comfortable, natural fabric for luxury garments. Yet the fact that the yielding of silk includes killing young moths in boiling water makes it controversial.
