When the worms have grown enough, they are put in baskets. From there, they will spin their cocoons in five days and will produce about three hundreds meters of silk each. The cocoons are then put in sunlight to avoid them undergoing their metamorphosis into mature moths. However, 20% of them reach the breeding process and the female moths will lay and hatch its eggs within nine to twelve days.
The cocoons are soaked in hot water in order to soften the sericin (also known as silk gum) which coat the fibres and stick the cocoons together. Silk threads are then unwound and reeled together to produce a single thread. Weavers at Angkor Silk Farm make both raw silk and fine silk that do not have the same texture at all. Sericin has not been completely removed from raw silk threads, which will give a rougher texture to the fabric at the end.
Genetically modified organism
Silkworm, the larvae stage of "Bombyx mori," is an economically important insect in sericulture. Scientists are developing strategies to enhance silk quality and quantity. There is also potential to use the silk producing machinery to make other valuable proteins. Proteins currently developed to be expressed by silkworms include; human serum albumin, human collagen α-chain, mouse monoclonal antibody and N-glycanase. Silkworms have been created that produce spider silk, a stronger but extremely difficult to harvest silk, and even novel silks.
