Investigation of the Process of Forming Twisted Yarn by the Technique of Separate Yarn Delivery to the Twisting Zone

详细

A new yarn twisting technique that involves separate yarn delivery to the twisting zone and a device for its realization are described. In such a twisting technique, slubbing and twisting processes are combined and the device for its accomplishment is a single-process one. Formation of twisted yarn takes place with a variable pitch, which causes variation of the twist angle and the force that compresses the strand, whereupon the twist angle and the compressive force change nonlinearly at the initial stage of formation.
