Abstract

In a spinning method of drafting supplied fibers at a predetermined total draft ratio and then spinning the fibers using a spinning member composed of a nozzle member having a nozzle hole, first, before yarn discharging spinning, the amount of fibers supplied to the spinning member per unit time in a normal spinning state is changed to the amount of fibers supplied per unit time during the yarn discharging spinning, the latter amount being different from the former amount, and after the yarn discharging spinning has ended, the changed amount of fibers supplied is returned to the amount of fibers supplied in the normal spinning state.
A yarn can be reliably generated for yarn discharging spinning. This improves the success rate of joining.
