Description

[Detailed description of the invention] The present invention is a method of twisting or disturbing a yarn containing short fibers in part (hereinafter referred to as yarn containing short fibers), which is made by aligning short fiber yarns and filament yarns. The present invention relates to a yarn processing device that can easily capture and remove short fiber waste that falls off from the yarn during the processing.

In recent years, many attempts have been made to subject yarns containing short fibers to crimping, intertwining, or loop processing by false twisting or agitating them with fluids such as air. The applied crimps, entanglements, loops, etc. and short fiber fuzz are combined to form a unique spun yarn, which is highly used because its appearance and texture match the tastes of recent clothing consumers. Processing such as crimping, entangling, or looping of yarn containing short fibers is generally carried out by the steps shown in FIG. 1. That is, short fiber yarn
Ya and multifilament yarn Yb are pulled together by a guide 1 to become a pulled yarn Yab, which passes through a feed roller 2 and is transferred to a yarn processing device 4 by a guide 3.
The processed yarn Y'ab is subjected to necessary processing such as crimping, intertwining, and looping, and is pulled out by a delivery roller 6 through a guide 5, passed through a guide roller 7, and then wound into a paper tube by a winding drum 8. It is wound up at 9. In this case, just before the aligned yarn Yab enters the yarn processing device 4, it is affected by the agitating fluid ejected from the yarn processing device 4, or it is swirled or disturbed within the yarn processing device 4. When the multifilament yarn Yb and the short fiber yarn Ya are aligned with each other, some short fibers that are weakly gripped fall off, become short fiber waste, and are scattered around the yarn processing device 4. However, they accumulate over time and fly into the running aligned yarn Yab, causing yarn breakage, which significantly reduces processing operability, and also adversely affects the quality of the processed yarn obtained. It's affecting. In addition, a large number of short fiber wastes are scattered and floating in the workplace, and especially when air is used as the agitation fluid for the yarn processing device 4, water and oil contained in the compressed air flow from the compressor may cause short fibers to scatter. It adheres to debris, scatters, and adheres to the walls, floors, and surfaces of machines such as guides in the workplace, and cannot be easily removed and accumulates, resulting in a deterioration of the working environment.

The present invention aims to solve the above-mentioned problems, improve operability and quality of processed yarn, and provide a yarn processing device that can prevent deterioration of the working environment.

That is, the present invention provides a yarn processing device, a fiber waste suction tube having a suction port close to at least one of a yarn inlet and a yarn outlet of the yarn processing device, a yarn guide hole, and a fiber waste suction tube. This yarn processing device includes a shielding box having an insertion hole and accommodating the yarn processing device.

The configuration of the present invention will be explained in detail below. FIG. 2 is a simplified vertical cross-sectional view of one embodiment of the yarn processing device of the present invention. Processed yarn from the Yab inlet 4a and the yarn processing device 4
A fiber waste suction pipe 10 having a suction hole 10' close to either one (the inlet 4a in the illustrated case) of the outlet 4b of Y'ab, or both the aligned yarn Yab and the processed yarn
It is characterized by comprising a shielding box 14 which surrounds and accommodates the yarn processing device 4, which is provided with yarn guide holes 11 and 12 of Y'ab and an insertion hole 13 for the fiber waste suction tube 10. In this example,
The number of fiber waste suction tubes 10 disposed with the suction port 10' close to the inlet 4a of the yarn processing device 4 is one, but if necessary, a plurality of fiber waste suction tubes 10 may be provided. The same applies when installing.

The yarn processing device used in the yarn processing device of the present invention includes, for example, a false twisting device that applies false twist to the yarn by rotation of a spindle or swirling airflow to give crimps, and a false twisting device that disturbs the yarn with a fluid. There are disturbance processing devices that add entanglement or create loops or slack.

In the yarn processing device of the present invention, the suction hole 10' of the fiber waste suction tube 10 is connected to the inlet 4 of the yarn processing device 4.
Since it is disposed close to the inlet 4a or the outlet 4b, the direction of scattering is only in the traveling direction or the opposite direction along the thread passage path, and as the distance from the inlet 4a or the outlet 4b increases, Most of the short fiber waste, which rapidly loses its direction and spreads and is difficult to remove by suction, can be suctioned in the vicinity of the inlet 4a or the outlet 4b. Regarding the directionality of short fiber waste, the following findings have been obtained through experiments. That is, for example, as the yarn processing device 4, the yarn inlet 4
When using an air entanglement processing device that blows air from both the a side and the outlet 4b side, weakly gripped short fibers in the drawn yarn Yab introduced into the processing device 4 are removed from the inlet 4a immediately before the introduction. The fibers are separated from the yarn Yab by the airflow ejected in the direction opposite to the direction in which the yarn travels, become short fiber waste, and are scattered in the direction opposite to the direction in which the yarn travels on the ejected airflow near the inlet 4a. On the other hand, from the yarn introduced into the yarn processing device 4, the weakly gripped short fibers have already come off as described above, and further short fibers will come off due to the disturbance action. The short fibers are hardly entangled without being entangled, and there is little scattering of short fiber waste from the outlet 4b side.
In addition, when a processing device that spouts fluid only from the yarn outlet 4b side is used as the yarn processing device 4, the fluid is sucked at the yarn inlet 4a side and a negative pressure state is created. Although there is no scattering of short fibers from the yarn outlet 4b, the short fibers that fall off due to the disturbance in the yarn processing device 4 turn into short fiber waste and ride on the fluid ejected from the outlet 4b. , scatters while maintaining directionality in the direction in which the yarn travels. Furthermore, even in the case of the yarn processing device 4 that does not use fluid, the short fiber waste is scattered in a directional manner due to the accompanying airflow generated by the progress of the introduced yarn.
The yarn processing device of the present invention is capable of efficiently suctioning and removing short fiber waste by skillfully utilizing the above-mentioned scattering direction of short fiber waste in the yarn processing device 4. Next, in the yarn processing device of the present invention, since the yarn processing device 4 is housed in the shielding box 14, short fiber waste that remains without being suctioned away near the inlet 4a or outlet 4b of the yarn processing device 4 is removed. The short fiber waste can be suspended in the shielding box 14, and most of the short fiber waste can be captured by the fiber waste suction pipe 10 while floating, so that the short fiber waste will not be scattered into the workplace or the like.

The yarn processing device of the present invention has the above-mentioned configuration and efficiently suctions and removes most of the short fiber waste generated during the yarn processing process. It can prevent adhesion and accumulation on walls, floors, etc., prevent deterioration in processing operability and the quality of the processed yarn obtained, and also greatly contribute to maintaining a good working environment.
