Problems solved by technology

[0003] However, in the above method, the core filament and the short fiber bundle are fed into the nozzle through the guide hole at the nozzle inlet, so that the position and tension of the core filament in the core yarn are unstable.
Therefore, the short fiber bundles cannot wrap the core yarn evenly, and the quality of the core-spun yarn produced has large inhomogeneity.

Embodiment 1

[0020] Such as figure 1 , shown in Fig. 2 (a) and Fig. 2 (b), a kind of that the present invention provides comprises vortex chamber 1, passes into the spindle shape yarn drawing tube 2 in the vortex chamber 1, the vortex tube 4 that is connected with fixed support 3 And the air jet hole 5 placed in the vortex tube 4, the center of the spindle-shaped yarn-drawing tube 2 is provided with a channel 6, and it is characterized in that a conical or cylindrical fiber and core wire guide are provided at the entrance of the vortex tube 4. The guide part 7 is provided with a needle-shaped core wire guide tube 8 at the top of the fiber and core wire guide part 7, and a width is set between the inlet 9 of the spindle-shaped yarn guide tube 2 and the needle-shaped core wire guide tube 8 A gap x of 2mm. The needle-shaped core wire guide tube 8 is penetrated with a core wire through hole 10 .

[0021] The fiber and core wire guiding part 7 is composed of a fiber spiral guiding surface 11 ...

Embodiment 2

[0026] Such as image 3 and Figure 4 As shown, the difference between embodiment 2 and embodiment 1 is that the fiber and core wire guiding component 7 is cylindrical. Other structures and their working principles are the same as those in Embodiment 1.

Embodiment 3

[0028] Such as Figure 5 As shown, the difference between Embodiment 3 and Embodiment 1 is that the axis of the core wire guide hole 12 forms an included angle β of 20 degrees with the axis of the forming fiber and the core wire guide member 7 . Other structures and their working principles are the same as those in Embodiment 1.

Abstract

The invention provides an air-jet vortex spinning device which can be used to produce core-spun yarn. The air-jet vortex spinning device comprises a vortex chamber, a spindle-like doffing tube, a vortex tube connected with a fixing bracket, and an air jet orifice arranged inside the vortex tube. The air-jet vortex spinning device is characterized in that a truncated cone shaped or cylindrical fiber and core yarn guiding assembly is arranged at the entrance of the vortex tube. The air-jet vortex spinning device has the advantages that the air-jet vortex spinning device is capable of enabling the short fiber bundles to evenly wrap and twine the core yarn, and the core-spun yarn produced by the device is even in quality. The air-jet vortex spinning device ensures that the core yarn is totally wrapped by short fiber bundles, thus improving wear resistance of the core-spun yarn.

Description

technical field [0001] The invention relates to an air-jet vortex spinning device, in particular to an air-jet vortex spinning device capable of producing core-spun yarns. Background technique [0002] The application date is Oct.11, 2000, the application number is US6370858B1, and the patent named CORE YARNPRODUCTION METHOD AND APPARATUS discloses a device and method for producing core-spun yarn. Wherein, the drawn staple fiber bundle is fed into a nozzle device and a hollow guide shaft body together with a core wire. The jet air is ejected from the nozzle hole, forming a vortex air flow in the nozzle, and the short fiber bundle is spirally wrapped on the core yarn under the action of the vortex air flow to form a core-spun yarn with real twist. [0003] However, in the above method, the core filament and the short fiber bundle are fed into the nozzle through the guide hole at the nozzle inlet, so that the position and tension of the core filament in the core-spun yarn are...
