Process Development of Silk Dyeing with Natural Dye Extracted from Plumbago Zeylanica Roots

摘要

Indian subcontinent possesses large plant resources of which, only little has been exploited so far. Anthraquinone, flavonoid, and indigotin compounds present in plants are used in several fields as dye and pigment. They are known as natural dyes. The Plumbago genus belongs to the Plumbaginaceae family and it is known due to its variety of biological uses, most of them attributed to the presence of naphthoquinones. In the present paper efforts were made to explore new potential source of natural dye, optimize the dyeing parameters viz., concentration of dye material, time of dye extraction, duration of dyeing. Plumbago zeylanica roots were used as natural dye for the dyeing of silk fabric. Plumbago zeylanica roots proved to be effective in imparting range of colours and shades to the silk fabric. The colours obtained on silk fabric were also appreciated by the potential consumers.
