摘要： A process and apparatus for producing open-end spun yarn using an electrostatic field produced by a pair of spaced electrodes in combination with a spinning rotor having an acutely inclined circumferential wall and a circumferential groove at the junction between the inner surface of the rotor wall and the planar surface of the rotor. Staple fibers are fed to the electrostatic field where they are generally linearly oriented and straightened and from which the fibers are aerodynamically withdrawn and fed onto the inner surface of the inclined rotor wall by means of a feed passageway tangentially oriented to the inclined rotor wall and having a gradually decreasing cross-sectional area so as to impose upon the fibers fed therethrough an ever-increasing velocity. The fibers centrifugally progress along the inner surface of the inclined rotor wall and gather in the circumferential rotor groove at which point the fibers begin to combine through cohesion both with other fibers in the groove and with the fibers in the tail of the yarn which is being twisted and withdrawn from the rotor, thereby forming a strand of fibers cohering to the tail of yarn previously formed. The formed yarn is continuously withdrawn, the continuous rotation of the rotor causing the tail of the yarn being withdrawn to be continuously swept along the inner circumference of the rotor thereby imparting twist to the strand of fibers at the tail, and also effecting the addition through cohesion of new fibers to the tail from the circumferential groove.

摘要： A process and apparatus for producing spun yarn using an electrostatic field produced by a pair of spaced electrodes, one of which surrounds the other to isolate the electrostatic field therebetween from external physical and electrical disturbances. Staple fibers are fed into the field through an aperture in the surrounding electrode for migration in the electrostatic field to a linear zone of increased field intensity from which the fibers are withdrawn and twisted to form a spun yarn, which may be done without the use of a core yarn or with a core yarn drawn through the linear zone and subjected to a false twisting operation to collect and twist the fibers thereon. Beyond the linear zone is another zone of increased field intensity for electrostatic collection of fly and other waste material. Suction is applied to remove the fly and other waste material from the electrostatic field and also serves to draw the feeding fibers through the aperture into the electrostatic field.
