Indian knitting hubs Ludhiana and Tirupur are now seeing the signs of revival. Ludhiana, the sweater and pullover destination, had witnessed slowdown in business continuously for the last two years because of the increasing length of summer, but in 2012 experienced a turnaround where every company sold out of its inventory. The struggling times for Tirupur market are also seemingly over with many zero discharge water treatment plants running in full capacity addressing the entire need of the industry. Even many of the power plants are under commission, setting the industry on a path to progress again.
