Preferably, the step (b) is: and taking down the small hair shaft, and selecting a spinning frame to spin the small hair shaft.
Preferably, the selected spinning frame is the one that is waiting for roving, and will be on standby within 30 minutes, with which the small spools are spun individually.
Preferably, the selected spinning machine is a spinning machine which is spinning and has a yarn which is not less than 300 meters left to be spun, one of the yarns of the spinning machine is removed and is changed into a small wool shaft, and then the yarn is spun.
Preferably, the selected spinning machine is a spinning machine that has just spun the next yarn, and the spinning machine is prepared to spin the small wool shaft while the spinning machine is spinning the next yarn.
Preferably, the swatch size woven in step (d) is (20-40) × (30-50) cm.
The invention has the beneficial effects that: the invention can be used for spinning the rough spinning yarn into the wool shaft with only a few rough yarn strips at the head of a batch for producing a new yarn batch in large scale so as to be capable of spinning the yarn on a spinning frame quickly, and the apparent quality such as color, color matching uniformity degree, defects and the like of the batch of yarn is tested after weaving so as to reduce the loss caused by unqualified batch.
