FAQ
Frequently Asked Questions
It means to remove the natural gum called 'sericin' from the silk fibers, a crucial step to make the silk soft, shiny, and ready for dyeing and weaving.
No, it is a rare, technical term used almost exclusively in specific industrial processes like textile production or oil refining.
Yes, it can be used for other natural fibers like ramie and in the process of refining vegetable oils to remove phospholipids and other mucilaginous compounds.
The process is called 'degumming'. The resulting material can be described as 'degummed' (e.g., degummed silk).
