The slowdown had stalled 11 projects involving an investment of Rs 3,500 crore, CMIE data shows.
The new projects, which were announced in the second quarter of this fiscal, included S Kumars' cotton viscose polyester weaving unit at Dhar (Madhya Pradesh), Samosaran Yarns' project at Thane in Mumbai and Patodia Filaments' polyester plant at Dadra and Nagar Haveli.
