Spinning apparatus and method for producing a false twisted spurn yarn

摘要

This invention is concerned with a spinning apparatus with an arrangement of a spinning nozzle which generates a rotating air current positioned close to the front roller and a pair of false twist units having hollow cylindrical rollers formed from elastic material which are positioned down stream from that spinning nozzle. As contact surfaces are formed that nip the fiber bundle by contacting the hollow cylindrical rollers having elastic properties, the fiber bundle can be reliably nipped in conjunction with the elasticity and the centrifugal force of the hollow cylindrical rollers. Even when driving the false twist apparatus at high speed a sufficient false twist can be imparted, a strong delivery power and unwinding power can be applied to the fiber bundle, and not only can high speed spinning be achieved, but also a strong, uniform spun yarn with little hairiness can be manufactured.
