Silk filature refers to raw silk manufacturing unit. The raw silk yarn filatures are obtained from the T. Narasipura factory, 25 kms away from the Mysore silk saree making factory. A single cocoon produces 800-900mts. of yarn, but usable yarn is only up to 400-600mts. The remaining yarn is used to produce Kashmiri carpets and is auctioned. The dead pupa remains and from it protein is extracted and used to make dog biscuits and lipsticks. They are sold for as less as 5-10 rupees for a kilogram. The unit manufactures raw silk yarn and transfers it to meet the raw material requirement of silk weaving factory in Mysore. The linear mass density of silk fiber is measured in units called dernier. The Mysore silk factory deals with 26-28 denier of the silk thread.
