Abstract
A spun yarn is manufactured from a sliver through an action of a first fluid swirling nozzle and a second fluid swirling nozzle capable of swirling a fluid in a direction opposite to the direction of swirling of a fluid in the first fluid swirling nozzle. Fibers detached from a sliver between a front roller assembly and a first fluid swirling nozzle are caused to wind positively around the twisted fibers during spinning operation.
