Problems solved by technology

[0004] In such a wrapping method, since the hollow spindle 5 needs to drive the double-sided bobbin 7 to rotate, the load is relatively large, the energy consumption is relatively high, and its rotation speed is restricted to a certain extent.
Moreover, before the covering action, the outsourcing yarn needs to be wound onto the double-sided bobbin dedicated to the hollow spindle spinning machine through the winding machine. After winding, the outsourcing yarn bobbin has less yarn, and it needs to be knotted to form knots after each replacement. Resulting in low quality of covered yarn
In addition, in the traditional covering method, the length of the covering yarn is limited. To complete a package of covering yarn, it may be necessary to replace multiple covering yarn packages, making it difficult to achieve continuous covering production

Embodiment 1

[0035] Embodiment 1: as figure 2 Shown, a kind of fancy yarn device comprises following structure:

[0036] The suspending body 2 is suspended above the suspending support body 1 without being in contact with the suspending support body 1, and its function is to allow the outer covering yarn to rotate freely there without being disturbed. The suspending body 2 and the suspending support body 1 are suspended in the form of electromagnetic levitation, and its internal structure and specific driving principle are consistent with those in the prior art, so they are not shown in the figure. The suspension 2 is used to support the core yarn reel 3 , and the core yarn reel 3 is placed on the suspension 2 during use, so that the core yarn 10 can be pulled out from above the suspension 2 .

[0037] Mounting frame 4, a mounting frame 4 is arranged on the suspension body 2, and a tensioner 5 is installed on the mounting frame 4, so that the core yarn 10 output by the core yarn drum 3 i...

Embodiment 2

[0049] Embodiment 2: As another suspension method, the suspension support body 1 is located above the suspension body 2 to make it in a suspended state, the installation frame 4 is fixed on the bottom of the suspension body 2, and is U-shaped, and the core yarn reel 3 is placed on the installation In the inner space of frame 4.

[0050] If the position of the outer yarn reel 8 is still arranged at the bottom, then as Figure 4 As shown, holes are opened on the suspension body 2 to facilitate the output of the core yarn from the core yarn reel 3, and the outer covering yarn released from the outer covering yarn reel 8 passes through the guide wire hole of the rotating part 6, and the rotation of the rotating part 6 drives it in the rotating part. The core yarn is covered in the space between 6 and the suspension 2, and the fancy yarn is output from the center hole. In order to ensure the suspension effect, a certain distance needs to be kept between the suspension support body...

Embodiment 3

[0053] Embodiment 3: The rotating part 6 can not only be arranged directly above the suspension body 2 and its core yarn reel 3 as shown in Embodiment 1, but also can be arranged directly below the suspension body 2 and its core yarn reel 3 .

[0054] Such as Figure 7 As shown, the longitudinal section of the main body of the rotating part 6 under the suspension 2 is T-shaped, and the ring-shaped protrusion is fixed on the upper part of the main body to form a whole. The yarn rotates on the outer circumference of the mounting frame 4 through the central hole and the guide wire hole of the rotating part 6, and the output core yarn is wrapped on the mounting frame 4 and then wound into a tube.

[0055] exist Figure 7 On the basis of the situation, the outsourcing yarn reel 8 can be placed on the top of the mounting frame 4, such as Figure 8 As shown, the outer covering yarn passes through the guide hole of the rotating part 6 to cover the core yarn in the space between the ...

Abstract

A fancy yarn manufacturing method comprises: using a suspended member (2) to suspend a bobbin (3) with core yarn (10) wound thereon, providing a space around the bobbin (3) of the core yarn for wrapping the core yarn (10) with outer-wrapping yarn (20), drawing the core yarn (10) from the bobbin (3) of the core yarn and winding the core yarn (10) onto a winding mechanism; enabling the outer-wrapping yarn (20) to bypass the bobbin (3) of the core yarn, and wrapping the outer-wrapping yarn (20) around the core yarn (10) to form the fancy yarn; and reeling out the fancy yarn from the winding mechanism. With this method, there is no need to drive the entire bobbin of the outer-wrapping yarn, facilitating high-speed wrapping and high-speed processing.

Description

technical field [0001] The invention belongs to the technical field of spinning, in particular, the invention relates to a production method of fancy yarn. Background technique [0002] Covered yarn is a kind of fancy yarn, which is divided into mechanical covering and air covering. The air-covered yarn is a yarn in which the outsourcing fiber filaments and spandex yarns are drafted through a certain type of nozzle at the same time, and the rhythmic network points are formed by the regular spray pressure of high-compression air. Mechanical covering is to continuously rotate and wrap the outer fiber filaments on the core yarn that is drafted at a constant speed. The mechanical covering yarn has a certain twist after being twisted. The core yarn is generally an elastic yarn, and the covering yarn combines the advantages of the core yarn and the outer covering yarn to make up for the defects of the single component filament. [0003] The mechanical covered yarn machine common...
