The influence of cocoon cooking condition and reeling speed on reeling performance of bivoltine hybrid cocoons has been studied. Study has been conducted using two cooking methods viz. single pan and pressurised, and nine levels of reeling speeds from 50mtrs/min to 210mtrs/min. It is observed that as the reeling speed increases reelability and raw silk % are found to decrease significantly. Slow speed reeling and pressurized cooking method give better reelability and raw silk recovery, whereas high speed reeling particularly with open pan cooking affect reelability and raw silk recovery significantly. It is also observed that as the reeling speed increases thread troubles are found to increase significantly. Results indicate that cooking of the cocoons to the required level and maintaining the reeling speed of 80∼120m/min are essential for achieving better reeling performance with optimum production from CSTRI multiend reeling machine.
