Description

[Detailed Description of the Invention] The present invention relates to an improved false twisting machine, and more specifically, to a processing machine for manufacturing spunlike yarn by applying disturbed air treatment to the false twisting machine.

Several devices have been proposed that add an air treatment mechanism to a false twisting machine, but in all of them, after performing the false twisting process (in the heating and untwisting area), air treatment is performed in the next area. According to this processing device, it has the following drawbacks.

In other words, the conventional method basically has a mechanism in which convergence due to the span effect of loops and fluff and the entanglement of the entire system is achieved only by disturbed air treatment, so advanced processing must be performed with emphasis on convergence. In this case, many short fibers break and become floating single fibers, so-called flies, which accumulate around the machine base.
This is causing problems in the process and quality control.

This tendency is particularly noticeable when acetate yarn is used.

In addition, fries are likely to occur during the post-processing of knitting, weaving, and dyeing finishing processes, causing various problems such as clogging of the tongue of the knitting needle and clogging of the filter of the dyeing machine.

On the other hand, even if we try to perform a light treatment that does not involve the generation of short fiber breakage, sufficient entanglement cannot be achieved, resulting in poor convergence, and the process tension during passing through the subsequent process causes the fibers to come apart, causing trouble. becomes.

In addition, yarns processed only by interlacing and convergence have little roundness, giving a paper-like feel with no volume at the final fabric stage, and can only result in a product that lacks the feel of a luxury product.

This invention is intended to eliminate the above-mentioned drawbacks,
The gist of the invention is a yarn processing device in which a disturbance air nozzle, a heater, and a swirling air nozzle are provided in the above order between a supply roll and a take-up roll.

The present invention will be explained in detail below with reference to the drawings. Fig. 1 is a side view showing an embodiment of the present invention, and in the same figure, a supply system 1
passes through a supply roll 3 and is looped and entangled by a disturbance air nozzle 6.

Here, it is important to suppress the occurrence of flies by relatively light air treatment, and it is acceptable even if the loops are coarse and the entanglement is insufficient.

Therefore, the structure of the disturbed air nozzle 6 used here is relatively simple and can accomplish the purpose.

Next, false twisting is carried out using the heater 7 and the rotating air nozzle 8, but here it is essential to set conditions so as to obtain a continuous untwisted yarn.

In this case, if you use air false twisting, the (
The tension ratio of untwisting/heating is extremely small, which facilitates untwisting, and has the advantage that even yarns with large irregularities, such as loop yarns, can be stably false-twisted.

This continuous untwisted false twisting process results in finer loops and improved convergence.

Thereafter, in the apparatus shown in FIG. 1, it is wound up via a take-up roll 9.

2 to 4 show other embodiments in which a plurality of yarns are supplied.

Although not shown in the drawings, it goes without saying that the present invention can also be applied to a two-stage heater type false twisting machine.

In this invention, the two issues of providing loops and convergence are accomplished through the two actions of disturbed air treatment and air false twisting, rather than being carried out all at once by disturbed air treatment as in the conventional method. It is something that

In other words, regarding the convergence, it is necessary to keep the air treatment to a relatively light level in order to suppress fries using the disturbance air nozzle, and to compensate for this lack of convergence, a continuous untwisted state occurs in the subsequent air false-twisting region. By this, it becomes possible to form a highly cohesive yarn consisting of interlacing plus continuous untwisting.

Regarding loops, since the disturbed air treatment is mild, only rough loops can be formed, but in the subsequent false twisting region, the rough and rough loops are strongly heated, and since the untwisting process is untwisted, it is possible to form only rough loops. The fineness of the loops is maintained and it is possible to form fine loop yarns.

This makes it possible to produce spunlike yarns that are mainly composed of fine loops with excellent cohesiveness, with almost no fly-outs occurring on the false-twisting machine, and with no associated troubles.Its industrial value is extremely high. It is.
