At the National Commodity and Derivatives Exchange, kapas prices for delivery in February climbed Rs 25, or 2.87 per cent, to Rs 895 per 20 kg, with an open interest of 52 lots.
Similarly, the most-active April contracts also went up by Rs 3, or 0.33 per cent, to Rs 901 per 20 kg, in an open interest of 3,066 lots.
Marketmen said the rise in prices was mostly due to speculative positions built up by traders on the back of rising industrial and export demand in spot markets.
