In order to overcome disadvantages mentioned above, a false twisting disk and the spacer rod yarn false-twisted to spinning section, the end face of false twisting disk is used with spinning section in the same plane, thus not to affect the spatiality of existing spinning section, after repiece, by spacer rod, spinning section pressed to false twisting disk, it is simple to repiece.Owing to false twisting disk does not affect the states such as the twist of the false twisting original yarn of disk output owing to turning on the contrary, improve the feasibility of technique.And, the speed of false twisting disk can regulate and reach to control the false twist efficiency of spinning section on the upside of false twisting disk, thus improves the performance of this section of yarn, is finally reached minimizing breakage, improves the purpose of yarn property.
Therefore, it is an object of the invention to provide the process for manufacturing ring spun yarn line and device.
Described process and device have and do not change the advantages such as the technology characteristics parameter of original spinning section output, Yarn connecting technique is easily operated.Regulation false twisting disk rotating speed reach improve yarn spinning performance, by improve spinning section the twist, reduce the final yarns twist thus obtain the property of final ring spun yarn line.
