Description

[Detailed Description of the Invention] The present invention relates to a processing device for long fiber products such as fabrics, and more specifically, to uniformly and effectively wrinkle textiles using highly twisted yarn in a rapid liquid flow. Related to devices that can.

Unlike the relaxing treatment of processed yarn knitted fabrics, the texturing process for highly twisted yarn fabrics involves applying strong mechanical vibration or It is necessary to process while applying shock.

As a conventional embossing treatment device for highly twisted yarn fabrics, there is a rotary drum washer that carries out the embossing treatment by placing the fabric to be treated in a rotating drum and turning the drum forward and backward into a high-temperature liquid.

Recently, continuous texturing devices have also been used, which apply vibration to a linear treatment tank having serrated side walls or cause a jet stream to impinge on the fabric being transferred without tension.

The former is capable of repeatedly subjecting the fabric to strong impact and striking, resulting in a good graining effect, and although various improvements have been made, its basic structure has remained unchanged for several decades, and it is still widely used today. It is being

However, when graining is performed using the rotary drum washer, the long fabric is fed into a spiral, so a selvedge binding process called Andon-kake must be performed manually to prevent the wound fabric from unraveling during processing. It has a defect that it should not be used.

Although the latter continuous texturing device solved the problem of operational inefficiency with the rotary drum washer, these devices were unable to obtain sufficient kneading action or impact action, and therefore the texturing effect was insufficient. The current situation is that it is not widely used because it is sufficient.

Therefore, an object of the present invention is to provide an apparatus that eliminates the above-mentioned drawbacks of the prior art and enables uniform and efficient texturing.

According to the present invention, a horizontally elongated retention tank temporarily retains long fiber products such as fabrics connected in a loop shape while moving in a meandering manner, and a treatment liquid injection unit connected to an outlet of the retention tank. , which has both ends connected to the inlet of the retention tank and the treatment liquid injection part, and forms an annular treatment passage with a transfer passage for transferring the textile product with a rapid liquid flow; Suction piping from at least one control port,
In a liquid flow type textile product processing apparatus, which forms a circulation path for the treatment liquid that reaches the treatment liquid injection part via a pump and a heat exchanger, and processes the textile product by circulating it.
The retention tank is configured to have an inclination in the downward direction so as to gradually become deeper in the advancing direction of the object to be treated at the rear thereof, and the transfer passage is configured to have an inlet connected to the treatment liquid injection section. A buffer plate is provided to be inclined at the side, and a buffer plate is provided at the inlet part of the retention tank at a predetermined distance from the outlet end of the transfer passage to absorb the textile product transferred in the rapid liquid flow in the transfer passage. In addition to colliding with this buffer plate, a perforated nest plate with a meandering prevention plate on the side surface is installed at an angle at a corresponding position below the buffer plate, and the textile product that has collided with the buffer plate is kept in the gas phase. A rapid liquid flow type textile product processing apparatus is provided, which is characterized in that the textile product is allowed to fall onto this root.

In other words, the present invention involves transporting a long fiber product such as a strongly twisted yarn fabric bound in a loop shape in a rapid liquid flow, and colliding it against a buffer plate in the gas phase in an annular processing passage to obtain the texture needed for the graining process. By applying a shock and repeatedly applying appropriate tension or no tension in a hot bath,
It enables grain raising processing that has the same effect as the grain raising process using a conventional rotary drum washer.
Moreover, it is possible to significantly streamline work efficiency.

As mentioned above, although the present invention exhibits extremely excellent effects when applied to the graining treatment of highly twisted yarn fabrics, it is not limited to the graining treatment of such textile products. Naturally, it can also be applied to the relaxation treatment of yarn fabrics, etc., and even in such cases, it exhibits remarkable effects that could not be obtained with conventional techniques.

In the accompanying drawings, FIG. 1 is a sectional view schematically showing a preferred embodiment of the processing apparatus of the present invention, and FIG. 2 is a schematic plan view of the nest plate portion of the apparatus shown in FIG.

The retention tank 1 is composed of a rear part 2, a central part 3, and a front part 4.

The rear portion 2 is inclined, and the angle of inclination is practically 5° or less with respect to the horizontal plane.

The central portion 3 is installed substantially horizontally, and the front portion 4 is tapered and installed at an angle.

A processing liquid reverse injection section 5 and a header portion 6 are connected to the front section 4 .

This header part 6 is formed into a substantially T-shape, and a guide roll 13 is provided in the center thereof, and a processing liquid spraying part 14 is provided in the lower part.

The transfer passage 7 for rapidly transferring the fabric, etc. is connected to the lower part of the treatment liquid injection part 14 at its inlet part 7a, and the outlet part 7b at the other end projects and communicates with the inside of the rear part 2 of the retention tank. ing.

The inlet portion 7a is provided at an angle, and the angle of inclination is practically 30 to 60 degrees with respect to the horizontal plane.

The retention tank 1, the reverse injection part 5, the header part 6, and the transfer passage 7 configured in this way form an annular processing passage.

The fabric etc. 8 connected in a loop shape moves in a meandering state while temporarily staying in the retention tank 1, and moves in a substantially straight line in the transfer section 7.

The buffer plate 10 is disposed in the rear part 2 and covers the open end of the outlet section 7b of the transfer passage with a predetermined distance between the buffer plate 10 and the open end of the outlet part 7b of the transfer passage. It is arranged to collide with the plate.

In addition, a large number of holes are formed in the buffer spray 10, and when the fabric etc. 8 collide, the processing liquid is separated from the fabric etc. and passes through the holes.

The buffer plate 10 is preferably provided with an inclination with respect to the horizontal plane, and the inclination angle is equal to the joint 11.
Further, the distance between the buffer plate and the open end of the outlet portion 7b can be adjusted by the guide shaft 12.

The angle and position of the buffer plate 10 can be set arbitrarily, but within a practical range, the angle θ is 20 to 45 degrees and the distance l is 100 to 150 m as shown in FIG.
m, and the angle θ2 is 50 to 80°.

The porous nest plate or scrae 9 is batsfurf.

The fabric, etc. 8 that collides with the buffer plate 10 falls onto the buffer plate 10 and is smoothly sent forward.

This inclination angle is 30~30 at angle θ3 as shown in FIG.
A practical angle is 70°.

Furthermore, a pair of anti-meandering plates 28 are provided on the sides of the scraper 9, and are configured to have gradually larger intervals in the direction of movement of the fabrics, etc., so as to keep the fabrics, etc. 8 in good order. .

In addition, 15 and 16 are suction pipes for drawing out the processing liquid in the retention tank 1, 17 is a pump, 18 is a filter attached with a wire mesh 19, 20 is a heat exchanger, 21 is a water inlet pipe, 22
23 is the steam inlet pipe, 23 is the water and drain outlet pipe, and 24 is the steam inlet pipe.
25 is a liquid supply valve, 25 is a drain valve, 26 is a treatment liquid reverse injection adjustment valve, and 27 is a treatment liquid injection adjustment valve.

The operation of the apparatus shown in the drawings will be explained in more detail below.

The fabric etc. 8 collides with the passage wall of the inclined entrance part 7a of the transfer passage 7 by the jet stream of the treatment liquid supplied from the treatment liquid spray part 14 in the annular treatment passage.

This inclination of the inlet portion 7a not only exerts an impact effect on the fabric etc. to create a grain effect, but also reduces the flow resistance of the rapid treatment liquid flow generated in the treatment liquid injection section 14, thereby increasing the flow resistance to the treatment liquid. can give a flow rate.

Thereby, the transfer speed of the fabric etc. passing through the transfer path 7 can be increased to 300 m7 minutes or more, particularly 300 to 600 m7 minutes.

Since the transfer path 7 is a narrow path, the fabric etc. 8 moves in this path in a substantially straight line and collides with the buffer play 10 when it exits the outlet section 7b.

The impact of this collision imparts a graining effect to the fabric, etc., and most of the processing liquid contained in the fabric, etc. passes through numerous holes provided in the buffer plate and is separated from the fabric, etc. .

As mentioned above, the inclination angle and mounting position of this buffer plate can be adjusted as desired, and therefore, efficient graining processing can be performed depending on the type and properties of the textile product to be processed.

The nest plate 9 is configured so that its inclination gradually decreases toward the front, and the meandering prevention plate 28 is also configured such that the interval between them gradually increases, so that the buffer plate can The fabrics and the like that have fallen onto the nest plate 9 in the gas phase after colliding with the air filter 10 are well tidyed up and smoothly moved one after another to the front of the retention tank.

The fabric and the like fed into the rear section 2 are sequentially moved from the center section 3 to the front section 4 according to the flow of the treatment liquid, while forming a slightly meandering block shape.

By giving the rear part 2 the slope as described above,
This movement of the fabric etc. becomes smoother, and the effect of reducing the required volume of treatment liquid in the retention tank can be obtained.

The fabric etc. 8 which has reached the front part 4 of the retention tank is pulled up into the header part 6 via a guide roll located in the center of the header part 6.

At this time, cloth handling is performed by the reverse jet of the treatment liquid in the treatment liquid reverse injection section 5, the tangles and the like of the cloth are loosened, and the cloth etc. are smoothly guided to the treatment liquid injection section 14 again.

Since this header part 6 is positioned higher than the level of the processing liquid due to the slope of the front part 4 of the retention tank, the guide roll 13 is positioned in the gas phase, increasing the transport speed of the fabric and the like.

It is preferable that the level of the treated liquid in the retention tank is set to be approximately at the middle of the height of the tank at the central portion 3 thereof.

By doing this, the collision of the fabric, etc. with the buffer play) 10 and the fall onto the nest plate 9 are completely carried out in the gas phase, and the separation of the fabric, etc. and the processing liquid is made efficient. As a result, an extremely effective impact effect is obtained and the fabric is not disturbed.

On the other hand, the processing liquid drawn out from the adjustment port of the retention tank via the suction pipes 15 and 16 is guided to the pump 17,
8 and is heated in the heat exchanger 20, and is supplied to the processing liquid injection unit 14 via the processing liquid injection regulating valve 27, and a part of it is supplied to the processing liquid injection unit 14 via the processing liquid reverse injection regulating valve 26. It is supplied to the reverse injection section 5.

According to the device of the present invention as described above, fabrics, etc. are transferred through the liquid flow at an extremely high speed in the annular processing passage, and strong rubbing and impact action are repeatedly performed in the transfer passage and at the entrance of the retention tank. At the same time, when falling from the buffer plate onto the nest board, it is further subjected to a striking action.

In addition, each component of the annular processing passage is individually subjected to appropriate packing action, spreading action, and appropriate repeated actions of tensioning and untensioning.

Therefore, if the present invention is applied to the embossing treatment of strongly twisted yarn fabrics, etc., extremely uniform and efficient embossing becomes possible.
