The invention discloses a processing technology of noil. The processing technology specifically comprises the steps of: S1, a cotton blowing step, i.e., a short flow process is adopted for the cotton blowing step, and beating is replaced by combing by reducing the beating points and reducing the beating speed; S2, a cotton combing step, i.e., the cotton combing step is performed by way of low tension traction and low doffer speed; S3, a roving step, i.e., the workshop temperature in the step is controlled at 27-30 DEG C, a channel is kept smooth, and the roving evenness CV is less than 4.5% during normal production; S4, a spinning step, i.e., the step adopts domestic equipment FA1508; S5, a spooling step: a full-automatic spooler is adopted, and the turning speed is controlled at 850 m/min; and S6, a mercerizing step, i.e., stretching at three times and retracting at two times are performed, then hot water washing is performed twice, and finally cold water washing is performed. By virtue of the processing technology disclosed by the invention, the product quality is remarkably improved; secondly, the utilization ratio of the equipment is increased, so that the labor force is reduced, the labor intensity of workers is reduced, and the manufacturing cost is lowered.
