Salem white silk or Salem Venpattu has its origin from Salem, a city in Tamilnadu. These silk textile products at the time of manufacturing are white in colour. After washing they gradually change to light sandal colour and thereafter deep yellow colour as it was in the beginning stage before bleaching. If the clothes do not change to the original colour, they are not pure silk. The chief attraction of the Salem silk fabric is its lustre. The water used for degumming has certain properties in order to impact lustre to silk. The water used in Salem possess this unique quality of impacting lustre to raw silk. This may be one of the reasons for the whiteness and shine of silk dhothi which has taken firm root in Salem.
