This invention discloses a negative ion yarn spinning process. During the transformation of the molten stream into nascent fibers, the strength gradually increases while the temperature gradually decreases. By setting up multiple cooling sections, the cooling air velocity in each section gradually increases vertically downwards. This gradual increase in cooling air velocity, based on the increasing strength of the nascent fibers, ensures cooling efficiency and allows the cooling temperature in each section to gradually decrease vertically downwards, resulting in a uniform temperature reduction of the nascent fibers. Ultimately, while ensuring cooling efficiency, this process avoids or reduces filament breakage. Furthermore, the initial use of a lower cooling air velocity prevents excessive fiber movement and adhesion. This invention also discloses a negative ion yarn spinning device that, while ensuring cooling efficiency, also avoids or reduces filament breakage.
