• The key goal of cocoon drying is to protect cocoon quality, preserve condition of cocoons
for reeling and prevent damage caused by long periods of storage. The first hazard is the
continued metamorphosis of the pupa. A newly emergent moth will pierce the shell
rendering the cocoon useless for conversion to raw silk. Exposure to excessive moisture
within the cocoon causes putrification and moulds.
• Sun Drying:
• No investment required to dry cocoons in bright sunshine. Clearly, this is only
possible in tropical and sub-tropical zones. Fresh cocoons are spread in thin
layers on a mat or planks of wood and exposed to direct sunlight. Depending
on the strength of the sun, the process takes two or three days. Though chip
and simple to employ, the main disadvantage is silk fiber’s sensitivity to
ultra-violet rays, with harm fiber strength and color. Since there are limited
facilities for quick marketing of cocoons, sun drying continues to be utilized
in many tropical and sub-tropical countries
