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.
Silk industry of Cheshire
Silk is a naturally produced fibre obtained from many species of the silk moth. In 1700 the favoured silk was produced by a moth (Bombyx mori), that used it to spin a closed cocoon to protect her larvae. These fed on the mulberry leaf which was grown in Italy. Silk fibres from the "Bombyx mori" silkworm have a triangular cross section with rounded corners, 5-10 μm wide. The silk is a protein called fibroin and it was cemented in place by the use of a gum, another protein called sericin. The cocoons were harvested and placed in troughs of hot water that dissolved the gum and allowed the single thread to be wound into a skein.
