Silk:- Explained in brief
by : Rahul Sharma
Silk:
Silk in its raw state is coated with sericin. It is necessary to remove this gum in order to develop the silk luster and dyeability. Historically, 25-30% soap, owf, was used for degumming. Synthetic detergent systems, such as higher alcohols and alcohol sulphates along the soda ash and boric acid have replaced soap to a large extent. Buffered alkalies, especially polyphosphates are frequently used with synthetic detergent systems. Strongly alkaline system must be avoided to prevent attack on the proteinaceous silk fibres.
