Studies on cross-linking of Sericin on Polyester fabric

摘要

Sericin is a protein material, which is adhered to the fibroin filaments while the formation of natural silk by the silk worm. The sericin content and its characteristics in natural silk varies from one variety to the other. There are four varieties of silk, either cultivated or naturally grown. They are Mulberry silk (Bombyx mori), Tasar (Antherea Mylitta), Muga and Eri. In India all the four varieties of silk are available. The sericin varies from 6-7% (muga) to 21-28% (mulberry). The sericin from mulberry cocoons were extracted using high temperature and high pressure technique. The Sericin so extracted is condensed and dried to form sericin flacks and powder for future use. The sericin is applied on to the polyester fabric in aqueous form followed by drying. The fabric then cross linked with cross linking agent and cured at 130℃. The cross linking agents used in my study are Formaldehyde, Glutaraldehyde and Modified DMDHEU.
