THERMAL ENERGY CONSERVATION IN ROTARY PRINTINGP. SADASIVAM, N. MOHANDAS GANDHI , S.V. SARAVANAN AND M. VARATHARAJAbstract Normally the machine which is used to print woven fabric is used to print knitted fabric. But the property of the knitted fabric is different from woven fabric. Tubular knitted fabric is having two layers when flattened. Fabric is elastic in nature. Normal machine can print one side and has to dry the paste second side again and we have to heat the fabric to dry to finish the printing of tubular knitted fabric it has to be printed side by side. But in this present machine both sides can be printed by passing the fabric once. In olden machine paste the fabric by printing one side and again we have to dry the fabric and paste and again we have to dry and print the second side. But in this method printing on both sides can be printed simultaneously. So the fabric can be heated only once to complete the printing. So the thermal energy required to heat the fabric once is conserved and is equal to Cpf(T2-T1) per kg of fabric printed
