Textile Engineering and Fibre Science Question on Finishing of cotton
One kg bone-dry cotton fabric is padded with water to obtain 80 % wet pick up. The temperature of the wet fabric after padding is 30 °C. Assume the specific heat of water to be 1 cal/(g.°C); the latent heat of evaporation of water to be 540 cal/g and the specific heat of cotton to be 0.3 cal/(g.°C). The energy (kcal) required to dry the fabric completely (in integer) is____
