Effect of Surface Modification Treatment on Gold Coated Zari Yarn And its Weavability Characteristics

Abstract

The Zari yarn is a three component yarn which consists of red silk thread wrapped around by a silver wire and coated with pure gold. The Zari yarn is a metalized yarn and is basically manufactured by wrap spinning technique. In this work the zari yarn components has been treated with plasma reactor using argon and oxygen medium. The zari yarn is also made by using three different silk varieties as a core material. In initial stage the silk yarn is also degummed by using enzyme and also by traditional method. The effect of plasma treatment in each stage has been examined. After plasma treatment the frictional properties of zari yarn is interpreted. The weavability factors for the zari yarn also measured in the research.
