Description

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 and rotating fabrics and other textile products with a liquid flow.

Conventional Technology Liquid jet dyeing machines and other liquid jet processing machines have been widely known for dyeing and other processing while forming fabrics and other textile products into loops or spirals and circulating them through a processing device using a liquid flow. has been developed and put into practical use.

For example, as a liquid flow type textile processing device having a horizontally long treatment liquid circulation path, there is Patent No. 912854 (Japanese Patent Publication No. 52-37112), in which both ends of the upper retention tank are tapered. A transfer section connected to these is provided, and the treatment effect in the retention tank is improved by rapidly passing the fabric through the transfer section using a treatment liquid spouting section.

Also, Utility Model Registration No. 1001205 (Utility Model Registration No. 1001205)
No. 34307) discloses a means for rapidly expanding the cross-sectional area in the passage, providing means for drawing out the treatment liquid and means for supplying the treatment liquid to the textile product inlet, and maintaining the liquid level above the inlet. There is.

Furthermore, Utility Model Registration No. 993774 (Utility Model No. 993774) describes a vertical treatment tank whose cross-sectional area gradually expands in the direction of progress of the processed materials in the passageway.
Publication No. 28369), Utility Model Registration No. 1021371 (Publication of Utility Model No. 15826, 1973) for a passageway with an expanding passageway that expands rapidly in an inclined manner in the direction of travel.
There is.

Problems to be solved by the invention In the above-mentioned prior art, patent No. 912854
In this issue, the purpose of the transfer section is to transfer fabrics, etc., and the aim is to achieve a retention treatment effect in a retention tank through rapid transfer. Therefore, when processing textile products that can withstand high cloth speeds, it is possible to shorten the processing time and be effective in preventing wrinkles from being fixed due to the reverse jetting part, but when processing textile products that can withstand high cloth speeds, In the case of textiles (for example, fabric weight 100 to 400 g/m ² ), there is a risk of scratches due to contact with the walls of the circulation path or wrinkles due to wrinkles.

Furthermore, although it is possible to prevent air bubbles from being mixed in 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 is Due to its presence, it cannot be used as is for thin fabrics.

Furthermore, Utility Model Registration No. 993774 and No.
The method of gradually expanding the cross-sectional area or the method of rapidly expanding the cross-sectional area shown in Publication No. 1021371 was also unsuitable for application to thin fabrics such as silk fabrics, palis, and ponzi fabrics because the floating state was different.

The present invention solves the above-mentioned drawbacks and difficulties of the conventional examples, and also prevents scratches caused by contact with the wall surface of thin fabrics such as palace, ponzi, 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.

Means for Solving the Problems 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 the outlet of the processing tank, and a processing liquid injection part, and a top processing tank having both ends at the inlet of the upper processing tank and the processing liquid injection part, respectively. and a lower processing tank connected to the annular processing passage, the annular processing passage having a high liquid level from medium liquid or higher to full liquid except for the roller part provided in the header part, and at least one part in the annular processing passage. A processing liquid circulation path configured to reach the processing liquid injection section from a suction port provided through a liquid suction pipe, a pump, and a heat exchanger, and at least one cross-sectional area provided in the lower processing tank. a liquid flow adjustment section that is a combination of a gradually expanding reducer section and a liquid suction section following the reducer section; and a liquid flow that is provided at the inlet of the upper treatment tank and has a gradually expanding cross-sectional area and a liquid suction section. The liquid flow processing device for textile products is characterized in that it comprises an adjustment section and an inclined section formed at the outlet section of the upper processing tank.

Effect In the present invention, since thin knitted fabrics and specially textured knitted fabrics that are prone to scratches and wrinkles are treated, the processing liquid in the processing circulation path ranges from medium to full liquid except for the roller part of the header part. The liquid level was set to . Then, connect the lower treatment tank and the upper treatment tank at both ends,
By creating an annular processing passage extending horizontally, the lower processing tank also became part of the processing tank. Therefore, unlike the conventional horizontally elongated processing tank, the lower part does not act as a transfer part to rapidly transfer the processed material, but instead has a liquid flow having a redeuse part whose cross-sectional area gradually increases and a liquid suction part following it. The adjustment section allows the objects to be processed to advance through the lower processing tank while being subjected to dyeing and other treatments in a folded state so as not to make strong contact with the inner wall surface of the processing tank, and then to be transferred relatively slowly to the upper processing tank. I started to be able to do it. In the apparatus of the present invention, there is no sudden expansion of the cross-sectional area, so there is no disturbance in the progress of the cloth.

At the inlet of the upper treatment tank, we have gradually expanded the cross-sectional area and provided a liquid flow adjustment section with a liquid suction section, so fabrics, etc. can be sent smoothly to the upper treatment tank even when the tank is almost full of liquid. . 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 including a lower processing tank and an upper 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 processing liquid level in the header section is such that the upper processing tank has a high liquid level, and only the rollers are protruding from the liquid level, so the fabric can be introduced smoothly without applying tension, and the fabric can be spread easily. The effects are starting to be expected.

Embodiment The drawing is a schematic sectional view of the apparatus of the present invention, and the processing tank has 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 6 denotes a liquid flow adjusting part whose cross-sectional area is gradually expanded and has a liquid suction part, and is also a connecting part between the lower processing tank 1 and the upper processing tank 2. The cross-sectional area of the liquid flow adjusting 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. Reference numeral 9 denotes an inclined part, which is provided at the outlet of the upper processing tank 2 and connected to the header part 10. Reference numeral 11 denotes a roller, which is installed in the header section 10 and projects above the liquid level when the upper processing tank 2 is set at a high liquid level. Reference numeral 12 denotes a reverse direction spraying section which acts to linearly spread the fabric etc. that is coming up onto the inclined part 9 and to push the fabric that is moving forward towards the rear. 13 is a liquid ejection pipe. Reference numeral 14 denotes a processing liquid injection section, which is installed at the lower end of the inlet of the header section 10 and connected to the lower processing tank 1. 15
is a liquid ejection pipe connected to the discharge side of the pump 16. 17 is a heat exchanger. The liquid jet pipe 13 is 2
One branch is connected to the reverse direction injection part 12, and the other is connected to the processing liquid inlet of the header part 10. The processing liquid injection part 1 is passed from the suction port 2a through the liquid suction pipe 8, pump 16, and heat exchanger 17.
The passage leading to No. 4 is a processing liquid circulation path. 18
indicates the object to be treated such as fabric.

In this embodiment, when the pump 16 is driven,
The liquid suction section 4, the liquid flow adjustment section 6, and the suction port 2a of the upper treatment tank 2 are connected to the liquid suction section 4, the liquid flow adjustment section 6, and the suction port 2a of the upper processing tank 2 via the liquid suction pipes 5, 7, and 8, respectively.
At the same time as the processing liquid is sucked in from the discharge side of the pump 16, the temperature is adjusted to an appropriate temperature via the heat exchanger 17, and the liquid is sent to the reverse direction injection part 1 through the liquid injection pipes 13 and 15.
2. Inlet in the header section 10 and liquid injection section 14
A treatment liquid is injected from each tank, and the treatment liquid is circulated between the lower treatment tank 1 and the upper treatment tank 2, and dyeing and other treatments are performed.

In the lower treatment tank 1, the fabric etc. 18 is transferred to the liquid injection section 14.
However, since the cross-sectional area of the reducer section 3 gradually increases, the flow velocity decreases and the fabric etc. spreads in the vertical direction.
Next, the flow rate is further reduced by the liquid suction part 4,
While maintaining the expansion in the vertical direction, the intervals gradually become smaller and the folded state is reached. In this state, the liquid flow continues to advance slowly, so that the fabric etc. advances in an orderly manner without folding or turbulence, is processed, 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 continues in an orderly manner until reaching the inclined portion 9. The rising fabric or the like is sorted by the reverse direction spraying section 12, and then rides on the rollers 11 in a stretched state. 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 traveling speed is reduced by the enlarged cross-sectional area of the reducer section 3 and the liquid suction section 4 within the lower processing tank 1, and the processing is performed during this period.

Furthermore, a liquid flow adjustment section 6 consisting of a liquid suction section and an enlarged section
upper treatment tank 2 while undergoing treatment.
processing continues. 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. It has now become possible to perform the process sufficiently continuously.

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.

Further, in the illustrated example, there is one reducer section 3 and one liquid suction section 4 provided in the lower processing tank 1, but
By installing a plurality of these, it is possible to adjust the progress of fabric and the processing state. Furthermore, the suction port 2a of the upper treatment tank 2 is not limited to one 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. This liquid flow treatment device can be used for thin fabrics such as palace, ponzi, dechine, etc., and specially textured fabrics such as artificial leather, pile, and car seats, as it can proceed in an orderly manner without causing any disturbance. became possible.

In particular, a combination of a reducer part and a liquid 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. According to
Unlike the conventional method of accelerating the cloth speed and reducing the bath temperature, it ensures the floating state of thin fabrics and specially textured fabrics in a full liquid state in the lower treatment tank and a high liquid state in the upper treatment tank.
By slowly progressing the process, 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 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.
