Degummase treatment of spun silk fabric

Treatment of spun silk fabric with the proteolytic enzyme Degummase improves the wettability and whiteness of the fabric without affecting its strength. The enzyme-treated fabric absorbs more dye as compared to untreated fabric. Dyeing of spun silk fabric under alkaline condition gives more uniformly dyed fabric as compared to that obtained on dyeing under neutral condition. However, dye uptake and dye fixation are higher under neutral condition.
