Abstract:

Silk has fascinated man continuously over the millennia thanother fabric. It is royal in its splendor and exotic and sensuous in itsradiance. It is highly versatile and hence known as Queen of Textiles. Bydegumming process the aesthetic appeal can be improved. The conventional methodof degumming silk by soap & alkali consumes more energy and time anddegrades the silk material. In the present technical era the textile industrydemanding high quality and new properties, especially in the field of silkprocessing in which we are almost lack in modern processing and finishing. Themultifunctional auxiliaries and energy conservation processes are the Primeconcern of the Textile Chemical processing industry. The researchers undergoingmany studies to short cut the processes without sacrificing the quality to meetthe scarcity of water & energy. One such study is utilizing the -CDtreatment in silk degumming process.

Cyclodextrins are cyclicoligosaccharides formed by the enzymatic modification of starch. They possess acage-like supramolecular structure, Because of their inclusion complex formingcapability, the properties of the materials with which they complex can bemodified significantly. As a result the present workdeals, for the first time, with the formation of a Beta-CD IC with a naturalprotein as guest, i.e., silk fibroin from Bombyx mori silkworm. . The process of -CDtreatment is carried out in two reverse cases of degumming processing, -CD treatment followed byconventional treatment and conventional treatment followed by-CD treatment,were put forward. Finally, the Weight loss, Absorbency & SEM analysis ofthe degummed silk fabrics and the K/S values (color depth) & colourfastness of the dyed silk fabrics were measured and compared with those ofconventional treated ones.
