Silk degumming process is a fundamental finishing process for silk yarn and silk fabric. The objective of degumming is remove the substrate such as silk gum (sericin), wax and some impurities from silk fibres. The principle of degumming process is breaking the peptide linkage of amino acid in sericin structure into a small molecule, which is soluble in water. The methods used for the degumming are the hydrolysis reaction performed by acid and alkaline, but these methods are not eco-friendly and same time they have a big problem on the surface area of silk. Hence the proteolytic enzyme have been used to solve this problem and shown promising results not only in the production level but also quality of silk. Since protease based degumming is eco-friendly which will be an additional advantage. Though the conventional protease are quite efficient for degumming but having some disadvantage like thermal and chemical stability which is one drawback has to solved, also alkaline protease can hamper the quality and physical appearance of silk as silk is quite sensitive to alkali and alkaline protease. The thermostable protease basically forms Geobacillus genus has been used for the enzymatic degumming of silk which are quite resistant to various chemicals and temperature. In this article we have summarized comparative analysis of detergent, conventional protease and thermostable protease for efficient degumming.
