His Highness Visakham Thirunal Rama Varma, the then Maharaja of Travancore took the initiative to start a spinning mill in Quilon city (now known as Kollam) which was then business capital of Travancore along the Malabar Coast. He donated the land to start the AD Cotton Mill in 1884. The land was handed over to National Textile Corporation in 1974. The NTC planned to privatize Parvathy Mills in 2005. The plant was added by the Board for Industrial and Financial Reconstruction who had listed it for revival in 2002. The plan was dropped after protests by the Parvathy Mills Workers Union. Along with many other mills in Mumbai, Coimbatore, Ahmedabad, Aurangabad, Akola, Nanded, Naini, Jaipur and Udaipur, Parvathy Mill was slated for redevelopment and modernisation in 2007 and 2012.
