Have you heard of the three brothers — KP Ramasamy, KPD Sigamani and P Nataraj? Most likely not. But those hailing from the textile town of Tirupur would know the trio since they run one of India’s biggest integrated textile units, KPR Mill. Eldest of the three, 71-year-old KPR started out as a powerloom fabric manufacturer in 1971 and with the help of his brothers, went on to create a textile giant straddling the entire value chain of yarn, fabric and garments.
