.Zari is a type of thread made of fine gold or silver wire used in traditional Indian and Pakistani garmentsThis thread is woven into fabrics, primarily made of silk to create intricate patterns. It is believed this tradition started during the Mughal period. The Padiyur Sarvodaya Sangh (PSS), a certified unit of the Khadi and Village Industries Commission (KVIC) near Kangayam, is the lone unit in South India where dyeing, weaving and zari production of silk saris are done. From cocoon to ornamental silks, the unit processes everything under one roof.
The cocoons collected from the farmers are separated quality-wise before being steamed and then reeled to make it into a yarn. After winding, doubling is done to the yarn and then it is twisted and dyed. Production manager Kuppusamy says, "We have a dyeing unit, the only one in the State to colour the silk yarn. We don't let the effluents spoil the environment. We treat it and use the water for our teak plantation." First, gold is made into a liquid form and then coated on the silver yarn.
