Description

Technical field: [0001] The invention belongs to the field of textiles, and relates to a rotor spinning composite yarn spinning device. Background technique: [0002] In the past 40 years, rotor spinning technology has developed rapidly, accounting for a large proportion of new spinning. Rotor spinning is also called open-end spinning, and twisting and winding are carried out separately. Therefore, compared with ring spinning, rotor spinning has the characteristics of high spinning speed, large package, and low cost. However, rotor spinning The spinning strength is low, and there are a considerable amount of entangled fibers on the surface of the rotor-spun yarn, which not only causes the twisting pattern on the surface to be disordered, but also affects the yarn strength. In order to improve the performance of the rotor-spun yarn, enrich the fancy varieties of the rotor-spun yarn , Filaments can be introduced in the spinning process of rotor-spun yarn, so that the filament...

Problems solved by technology

[0003] A Japanese patent (Patent No. Hei 2-80624, 1990) provides a method for spinning wrapped yarn on an improved rotor spinning machine, such as figure 1 As shown, the method is to control the feeding amount of the filament 1 through the yarn guide 2, the tension control device 5 and the feeding roller 3. During spinning, the internal and external pressure difference is generated by the high-speed rotation of the rotor with a center hole 8. Suction-feed the filament 1 into the rotor 8 with a center hole and wrap it on the surface of the short fiber to form a wrapped yarn 17, and change the position, length, diameter, number of hollow tubes 7 and the rotor 8 with a hole The rotating speed changes to obtain wrapping yarns 17 of different appearances. The shortcoming of this spinning method is that (1) the wrapping yarns spun are all made of short fibers to form the yarn core, and the long filament 1 is located on the surface layer, and the yarn structure and The nature is relatively simple; (2) the change of the length, diameter and number of hollow tubes 7 will inevitably affect the parameters of the hollow tubes 7, which is difficult to achieve during the adjustment of the spinning process, and the hollow tubes 7 extend into the middle hole of the belt The inside of the rotor 8 will inevitably affect the airflow in the rotor 8 with a middle hole, thereby affecting the formation of the wrapped yarn; (3) this spinning method cannot guarantee that the hollow tube 7 will not rotate during the spinning process, and once Rotation is likely to cause filament winding or even breakage, making the spinning process difficult to proceed normally; (4) The tension control device 5 of filament 1 is located before the feeding roller 3, which cannot really effectively control the tension of filament 1 during spinning
