Embodiment 1

[0028] Polyester filament is used to obtain stable tension after passing through the tension tension disc 5 and the yarn guide 4 with multi-curved circular grooves, and then feed the overfeed top roller pair 3 under stable tension, and the rotation of the current roller 14 is transmitted through the bridging roller 1 After feeding the speed-regulating roller 2, the speed-regulating roller 2 drives the overfeeding roller pair 3 to output polyester filaments, and then feeds them into the jaws of the front roller through the yarn guide hook 9 which is installed on the positioning guide rod 7 and the slider 8 and can move left and right 13. The nip 13 of the front roller for overfeeding or folding output converges and twists the sliver sliver to form an overfeeding wrapped composite yarn 12 . The specific composite spinning process parameters are shown in the table below.

Embodiment 2

[0030] Adopt spun silk to obtain stable tension after tension tension disk 5 and multi-bending circular groove yarn guide 4, then feed overfeed top roller pair 3 under stable tension, and the rotation of current roller 14 is passed to by bridging roller 1 After the speed regulating roller 2, the speed regulating roller 2 drives the overfeeding roller pair 3 to output silk, and then feeds the front roller jaw 13 through the yarn guide hook 9 which can move left and right installed on the positioning guide rod 7 and the slider 8, The nip 13 of the roller before overfeeding or folding is output and the wool sliver is converged and twisted to form an overfeed wrapped composite yarn 12. The specific composite spinning process parameters are shown in the table below.

Embodiment 3

[0032]Cotton yarn is used to obtain stable tension after being passed through the tension tension disc 5 and the yarn guide 4 with multi-curved circular grooves, and then fed into the overfeed roller pair 3 under stable tension, and the rotation of the current roller 14 is transmitted to the adjusting roller 1 through the bridging roller 1. After the speed roller 2, the speed regulating roller 2 drives the overfeed top roller pair 3 to output cotton yarn, and then feeds the front roller jaw 13 through the yarn guide hook 9 which is installed on the positioning guide rod 7 and the slider 8 and can move left and right. Or fold and output the front roller nip 13 and the polyester strands to converge and twist to form an overfeed wrapping composite yarn 12 . Such as figure 1 and figure 2 shown. The specific composite spinning process parameters are shown in the table below.

Abstract

The invention relates to an overfeed composite spinning device and method suitable for ring spinning and applications of the overfeed composite spinning device and method. The method comprises the following steps of: driving an overfeed mechanism by the rotation of a front roller so as to lead filament bundles or yarns to be overfed in the front roller; and then enabling the filament bundles or yarns together with synchronously feeding short fiber strands to go out of a jaw of the front roller to be twisted and combined into double-component composite yarns. The overfeed buckling wrapping effect of the composite yarns is obtained by adjusting the overfeed amount and the feeding angle of the overfeed mechanism. The device for implementing the method comprises a tensile controller for controlling the tensile force of the externally tied filament bundles or yarns, the overfeed mechanism and a synchronous displacement locator, and is capable of really fulfilling the purpose of forming the yarns through the short fiber strands by buckling wrapping. The composite spinning method is special, and easy to implement; and the corresponding device is simple in structure, can be conveniently installed, and can be used for the wrapping composite spinning of short fibers on a ring spinning frame.

Description

technical field [0001] The invention relates to an overfeed composite spinning device in the field of ring spinning and a composite spinning process using the device. Background technique [0002] Core yarn and wrap yarn fabrics have a special appearance and maintain a good feel and comfort, so they are very practical spinning methods. The key technology of spinning this type of wrapped composite yarn on the traditional ring spinning machine lies in the overfeeding method and device of the filament bundle or yarn. Many scientific researchers and textile machinery manufacturers at home and abroad have conducted relevant research and produced some machinery and accessories. The usual method is to introduce the filament yarn into the middle roller or front roller through the yarn guide rod, Before entering the front roller, it is merged with short fiber strands and twisted to form a composite yarn. For example, Fan Yonghui’s patented wrap spinning technology suitable for spinn...
