Degum, a verb, is a term used in the processing of natural fibers, particularly silk, to remove the gummy substances present in the raw material. The process of degumming involves the elimination of the sericin, a natural adhesive, which hardens and stiffens the silk fibers. This helps to improve the texture and quality of the silk fabric.
In a broader context, degumming refers to the removal of gum or sticky residues from various materials or surfaces. It describes the process of eliminating adhesive substances or gums that might impede proper functioning or affect the aesthetic appearance of a product.
Degumming techniques may vary depending on the application and materials involved. In silk degumming, for instance, the raw silk is typically immersed in a degumming solution, which can be made from chemicals or natural substances like soap or enzymes. This solution breaks down the sericin and allows for its removal either by rinsing or mechanical agitation.
Besides silk, other fibers like hemp and flax may also undergo the degumming process to enhance their quality and usability. In the food industry, degumming is employed in the vegetable oil refining process to eliminate unwanted impurities and gums from the oil, improving its flavor, stability, and clarity.
Overall, degumming is a fundamental process utilized across various industries to remove sticky substances, enhancing the performance, appearance, and quality of the materials involved.
