The popularity of silk is more confined to super-rich or haute couture; silk is now an affordable luxury for the middle class in Europe and USA, and continues to hold its way in Asia as traditional ceremonial wear. The present source book traces recent global status of silk country wise and describes in depth the sericulture practices followed in both in temperate and tropic regions of the world, as also silk processing, and marketing of raw silk, finished silk and ready-to-wear including high fashion couture creations of Italy, France and Switzerland. The book, therefore, attempts to fill a void in the current information available in English on the world status of sericulture and silk. We presume it would definitely interest scientist, technologists and students connected with the textile industry as also the textile designers, converters, importers and exporters the world over. It would also help the boutiques, buying-selling organizations, and chain department stores and specially stores to understand why silk sells and is superior to other textiles. As no comprehensive book on silk has been published so far, this source book covers the entire global scenario of silk as it has entered very successfully in the 21st Century.
