This experiment was carried out to investigate the cocoon reeling condiditions required to technical balance work on the automatic silk reeling machine. The results obtained were as follows. 1) Reasonable reeling velocity with regard to raw silk yield and to reeling efficiency varied according to cocoon reelability. It was observed to be about 150m/min on good reelability cocoon (850m of nonbreaking bave length), about 120m/min on medium reelability cocoon (650m of nonbreaking bave length) and from 90m/min to 120m/min on bad reelability cocoon (500m of nonbreaking bave length) 2) Low temperature drying of cocoon (T) improved the reelability of cocoon, but increased the reeling accidance with deteriorating the quality of raw silk more than the control(T) or high temperature drying of cocoon (T). No significant difference was observed in its raw silk yield and silk by-product with regard to cocoon drying temperature. 3) Incomplete drying of cocoon (T) improved the reelability of cocoon, but increased the reeling accidance with deteriorating the quality of raw silk more than the control(T) or over drying of cocoon(T). No significant difference was observed in its raw silk yield and silk by-product with regard to cocoon drying degree. It was cocoon drying condition of cocoon was the control(T) or high temperature(T) rather than low temperature (T) in cocoon drying process. Control (T) or over drying of cocoon (T) was adequate rather than incomplete drying of cocoon (T) for the improvement of the quality of raw silk on the automatic silk reeling process. 4) It was found that the reasonable cooking condition of cocoon was optimum cooking with 4 of reeling temperature or incomplete cooking with 45 of the reeling temperature in the automatic silk reeling of the domestic cocoon.
