The invention provides a method of preparing acetate fiber bunches in good production efficiency in which solvent content is very low, and acetate fiber bunches thereby. The acetate fiber bunches in which solvent content is less than 0.10 quality% is obtained according to the following procedures: a procedure of stock solution preparation, namely dissolve raw polymer at the solvent to prepare thestock solution; a procedure of spinning, namely spit out the stock solution from a nozzle, and obtain primary fiber bunches after volatilization by heating; a procedure of water & curling: supply water to the primary fiber bunch to make them curl, so as to obtain the primary fiber restrain with water rate 23 to 50 quality%; a first drying procedure: dry the primary fiber bunches that get through the procedure of water & curling at a temperature higher than boiling point of the solvent and lower than 85 DEG; a second drying procedure: dry the primary fiber bunches after the first drying procedure until water rate up to an expected value to get the acetate fiber bunches.
