DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a liquid flow processing apparatus for textile products, which performs treatments such as dyeing, scouring, or bleaching while circulating cloth or other textile products with a liquid flow.

2. Description of the Related Art Liquid jet dyeing machines and other liquid jet processing machines that dye or otherwise process fabrics and other textile products while forming them into loops or spirals and circulating them through a processing device using a liquid flow have been widely known. has been developed and put into practical use.

For example, as a processing device for liquid flow-type edge m products having a horizontally long processing liquid circulation path, Japanese Patent No. 912854 (Japanese Patent Publication No. 52
-37112 Publication), in which both ends of the upper retention tank are tapered, a transfer section is connected to these ends, and the processing liquid is spouted out to rapidly pass the fabric through the transfer section. This is designed to improve the treatment effect in the reservoir.

In addition, Utility Model Registration No. 1001205 (Utility Model Registration No. 1001205
No. 4307) discloses a means for rapidly expanding the cross-sectional area in the passage, providing a treatment liquid drawing means and a treatment liquid supply means to the textile product inlet, and maintaining the liquid level above the inlet. There is.

Furthermore, Utility Model Registration No. 993774 (publication of Utility Model Publication No. 47-28369), which is a vertical treatment tank whose cross-sectional area gradually expands in the direction of progress of the processed materials in the passageway, Utility Model Registration No. 1021 for a device with an expanding passageway that expands rapidly in an inclined manner in the direction of
No. 371 (Utility Model Publication No. 48-15826).

Problems to be Solved by the Invention In the prior art as described above, in Patent No. 912854, the purpose of the full-force feeding section is to transfer fabrics, etc., and the rapid transfer improves the retention treatment effect in the retention tank. It was aimed at Therefore, when processing textile products that can withstand high cloth speeds, time can be shortened, and effects such as preventing wrinkles from being fixed due to the reverse jetting section can be seen.1. W'I style thin fabric (for example, fabric weight 10
0 to 40 C1 g/m'), etc., there is a risk that scratches may occur due to contact with the wall surface of the circulation path or wrinkles may occur due to eye wrinkles.

Furthermore, although it is possible to prevent the inclusion of bubbles by having a processing liquid supply means above the inlet as in Utility Model Registration No. 1001205, the distance from the guide roll to the liquid surface is long, and this air layer Due to the presence of , it cannot be used as is for thin fabrics.

Furthermore, utility model registration No. 993774 and No. 1021
The one that gradually expands the cross-sectional area shown in Publication No. 371,
Also, for rapid expansion, the light is not suitable for application to thin fabrics such as silk fabrics, palaces, and pondas because the floating state is different.

The present invention solves the drawbacks and difficulties of the conventional examples as described above, and also prevents scratches caused by contact with the wall surface of thin fabrics such as palis, ponda, dechine, and specially textured fabrics such as artificial leather, pile, and car seats. The purpose of this invention is to prevent the occurrence of curling and the like due to the jet flow, and to smooth the flow of the processing liquid and improve the processing effect by appropriately adjusting the speed of the cloth.

In order to achieve the above object, the present invention provides a liquid flow processing apparatus that performs dyeing or other processing while circulating fabric or other textile products by a liquid flow in a processing liquid circulation path. , an upper processing tank having a processing tank extending in a substantially horizontal direction, a header part connected to an outlet of the processing tank, and a processing liquid injection part; and an upper processing tank having an inlet of the upper processing tank and a processing liquid injection part, respectively. An annular processing passage constituted by a lower processing tank connected at both ends, and at least one suction port provided in the annular processing passage, leading to the processing liquid injection part via a liquid suction pipe, a pump, and a heat exchanger. a liquid flow adjustment unit which is a combination of the processing liquid circulation path configured as above, and at least one reducer unit provided in the lower eight processing tank, which gradually enlarges the cross-sectional area, and a liquid suction unit following the reducer unit; a liquid flow adjusting part provided at the inlet of the upper processing tank and having a liquid suction part with a gradually expanding cross-sectional area; a slope part formed at the outlet of the upper processing tank; and a liquid flow adjusting part provided in the header part. The present invention provides a liquid flow processing device for textile fa products, which is characterized by comprising a roller and a roller.

Function: Since the present invention targets thin knitted fabrics and knitted fabrics with special textures that are prone to scratches and wrinkles, the processing liquid in the processing circulation path is completely drained from the middle liquid to the top, except for the roller section of the header section. The liquid level was set to high. By connecting the lower processing tank and the upper processing tank at both ends to form a horizontally extending annular processing passage, the lower processing tank also became a part responsible for processing as the width of the processing tank. Therefore, unlike the conventional horizontally elongated processing tank, the lower part does not act as a transfer part to quickly transfer the processed material, but instead has a reso-use part whose cross-sectional area gradually increases and a sludge suction part that follows it to adjust the liquid flow. Depending on the section, the object to be treated is folded so as not to come into contact with the inner wall of the processing tank, and progresses through the lower processing tank while being subjected to treatments such as dyeing, and is transferred relatively slowly to the two-part processing tank. In the device of the present invention, which has been designed to be able to move freely, there is no sudden expansion of the cross-sectional area, so disturbances in the rightward movement state do not occur.

At the inlet of the first-part treatment tank, we have gradually expanded the cross-sectional area and provided a liquid flow adjustment part with a liquid suction part, so even when the liquid is almost full, fabrics, etc. can be sent smoothly to the upper treatment tank. can. In the upper treatment tank, the fabric is folded into a large shape, accumulates there, and is gradually moved. Adjustment of movement of the processing liquid is performed by at least one liquid suction section provided in the center.

There is a slope at the outlet of the upper treatment tank, and the cloth is sorted and aligned while it climbs the slope. The rolls in the header part do not apply tension to the fabric or cause slips, and have a spreading effect, so that the fabric can be handled satisfactorily.

As mentioned above, the processing tank is of a two-stage type with a lower processing tank and a two-part processing tank, and although the movement of the fabric is relatively slow, dyeing and other processing operations can be carried out reliably during this time. . In addition, the treatment liquid level in the header section is such that the upper treatment tank has a high liquid level, and the rollers are only protruding from the liquid level, so there is no tension applied to the fabric, allowing for smooth introduction and expansion. 'lIj effect can now be expected.

The embodiment drawing is a schematic sectional view of the apparatus of the present invention, and the processing tank includes a lower processing tank 1 and an upper processing tank 2 installed in parallel.

They extend almost horizontally and are connected at both ends to form an annular processing passage.

Reference numeral 3 denotes a liquid adjustment section 1i, which is a reducer section whose cross-sectional area is gradually expanded, and which also has a liquid suction section 4. Reference numeral 5 denotes a liquid suction pipe, and reference numeral 6 denotes a liquid flow adjustment part that gradually increases the cross-sectional area and has a liquid suction part, and is a connecting part between the lower processing tank 1 and the upper processing tank 2. The cross-sectional area of the liquid flow adjustment section 6 was expanded by making the upper wall surface horizontal and gradually expanding the lower wall surface.

7 is a liquid suction part.

A liquid suction pipe 8 is connected to a suction port 2a for adjusting the processing liquid in the upper processing tank 2. 9 is an inclined part, and upper processing tank 2
The header section 10 is connected to the header section 10. A roller 11 is installed in the header section 10 and projects above the liquid level when the two-part treatment tank 2 is at a high liquid level. 12
The reverse-direction spraying section acts to straighten the fabric, etc. that rises onto the tilting section 9, and to push the advancing fabric backwards. 13 is a liquid ejection pipe. Reference numeral 14 denotes a processing liquid injection unit, which is installed at the lower end of the header unit 10 and is connected to the lower processing tank 1. Reference numeral 15 indicates a liquid injection pipe, which is connected to the discharge side of the pump 16. It is a heat exchanger.The liquid ejection pipe 13 is branched into two parts, one of which is connected to the reverse injection part 12 and the other connected to the processing liquid inlet of the header part 1o.The liquid is injected from the suction port 2a. suction pipe 8,
The passage leading to the treatment liquid injection section 14 via the pump 1B and the heat exchanger 17 is a treatment liquid circulation path. Reference numeral 18 indicates an object to be treated, such as a cloth.

In this embodiment, when the pump 16 is driven, the liquid suction part 4 and the liquid flow adjustment part 6 are connected through the moat suction pipe 5.7.8, respectively.
At the same time, the treatment liquid is sucked in through the suction port 2a of the upper treatment tank 2, and at the same time, from the discharge side of the pump 16 via the heat exchanger 17,
The temperature is adjusted to an appropriate temperature, and the liquid ejecting pipe 13.15 is used to inject the liquid into the reverse direction injection section 12 and the header section l.

The treatment liquid is injected from the inlet and the liquid injection part 14 respectively, and the treatment liquid is circulated between the lower treatment tank 1 and the upper treatment tank +1!2, and dyeing and other treatments are performed.

In the lower treatment tank 1, the fabric, etc. 18 is transported by the liquid flow of the liquid jetting part 14, but since the cross-sectional area of the reducer part 3 is gradually expanding, the flow velocity decreases and the fabric, etc. moves in the vertical direction. Then, due to the liquid suction section 4, the flow rate is further reduced, and while maintaining the expansion toward the lower blade, the gap gradually narrows, resulting in a folded state. In this state, the liquid flow continues to advance slowly, so that the fabric, etc., does not become turbulent when folded back, and progresses in an orderly manner, where the treatment is performed and transferred to the inlet end of the upper treatment tank 2.

Here, the object to be processed is further advanced into the upper processing tank 2 in a folded state by the liquid flow adjustment section 6 consisting of a liquid suction section and an enlarged section. By adjusting the degree of accumulation and progress by the suction port 2a, the process is continued in an orderly manner until reaching the inclined portion 9. The rising fabric etc. is handled by the reverse direction spray section 12, and the stretched fabric is sent to the roller 1! Get on. The fabric and the like transferred to the inlet of the liquid injection part 14 will be circulated again by the liquid flow.

While the fabric or the like is being circulated, its advancing speed is reduced by the enlarged cross-sectional area of the reducer section 3 and the liquid suction section 4 within the lower processing section 11!1, and processing is carried out during this period.

The liquid is decelerated by the liquid flow adjustment part 6, which roughly consists of a liquid suction part and an enlarged part, and is introduced into the upper treatment tank z while undergoing treatment, where the treatment is continued. During this time, the fabric 18 does not come into strong contact with the wall surface of the processing tank, so the processing progresses smoothly without causing scratch marks or fixing of wrinkles. However, it became possible to overdo it continuously enough.

In addition, although the example showed the example which circulated between a lower processing tank and an upper processing tank, it is not limited to this. For example, a plurality of units may be connected in a spiral manner.

In addition, a reducer part 3 and a liquid suction part 4 provided in the lower processing tank 1
In the illustrated example, there is one at a time, but by installing a plurality of these, the progress of the fabric and the processing state can be adjusted. Furthermore, the suction port 2a of the upper treatment tank 2 is not limited to the -. location.

Effects of the Invention Since the present invention has the above-described configuration, the liquid flows through the annular processing passage consisting of the lower processing tank and the upper processing tank on a relatively slow flow without strongly contacting the wall surface or overtaking. Because it can be progressed in an orderly manner without causing any disturbance or disturbance, it can be used for thin fabrics such as palace, bonji, dechine, artificial leather, etc.
This liquid flow treatment device can now be used for specially textured fabrics such as piles and car seats.

In particular, a combination of a reducer part and a bush suction part in which the cross-sectional area of the lower treatment tank is gradually expanded, and a liquid flow adjustment part in which the cross-sectional area at the inlet end of the upper treatment tank is gradually expanded and a liquid suction part is provided. This method ensures that thin fabrics and specially textured fabrics are suspended in a full liquid state in the lower treatment tank and in a high liquid state in the upper treatment tank, unlike the conventional method of accelerating cloth speed and lowering the temperature. By processing by progress, it is possible to fix threads and wrinkles on the fabric, and it is possible to transfer the fabric in an orderly manner without causing any wrinkles, making continuous processing possible.

Since a roller is used in the header section instead of a bar-type reel, the liquid spreads in this area and prevents fraying of the fabric and wrinkles of the rope.
