Description

[Detailed description of the invention] Industrial application field This invention is a liquid flow treatment device for textile products that performs treatments such as dyeing, scouring, or bleaching while circulating fabrics and other textile products with a liquid flow. Regarding the adjustment section.

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 fabric is rapidly passed through the transfer section by a reverse direction injection section and a treatment liquid ejection section, thereby improving the processing effect in the retention tank.

Also, Utility Model Registration No. 1001205 (Utility Model Registration No. 1001205)
Japanese Patent No. 34307) discloses means for maintaining the liquid level above the inlet by providing a treatment liquid supply means to a treatment liquid drawing means and a textile product inlet.

Problems to be solved by the invention In the above-mentioned conventional technology, 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.

The present invention solves the drawbacks and difficulties of the conventional examples as described above, and also prevents special textured woven and knitted fabrics such as palace, ponzi, chasidos, and other thin fabrics, artificial leather, pile, and car seats from coming into contact with the wall surface. 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 and other treatments while circulating fabrics and other textile products by a liquid flow in a processing liquid circulation path. An upper processing tank has 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 an upper processing tank having both ends at the inlet of the upper processing tank and the processing liquid injection part, respectively. An annular processing passage is provided by a lower processing tank connected to the annular processing passage, and at least one suction port provided in the annular processing passage leads to the processing liquid injection part via a liquid suction pipe, a pump, and a heat exchanger. A processing liquid circulation path is provided, and a porous suction section is provided at the inlet of the upper processing tank, the upper surface of which extends horizontally and the lower surface gradually expands to adjust the progress of the fabric on the upper surface. The inlet of the chamber was connected to the end of the lower processing tank via a grooved ring and an O-ring, and was used as a liquid flow adjustment part in a liquid flow processing apparatus for textile products that was adapted to expand and contract due to thermal expansion.

Effect In this invention, since thin knitted fabrics and specially textured knitted fabrics that are prone to scratches and wrinkles are to be treated, the processing liquid in the processing circulation path, except for the roller part of the header part, ranges from medium to full. The liquid level was set to high. 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.

A porous suction section is installed at the entrance of the upper treatment tank, with the upper surface extending horizontally and the lower surface gradually expanding.
The lower surface is designed to expand as the speed decreases, allowing fabrics and the like to be smoothly fed from the middle liquid to the upper processing tank which is almost full of liquid. In the upper treatment tank, the fabric is folded into a large shape, accumulates there, and is gradually moved.

Embodiment The drawing is a schematic sectional view of the device 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 flow adjusting part which is a reducer part whose cross-sectional area is gradually enlarged and which continues to have a liquid suction part 4. 5 indicates a liquid suction pipe. 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 adjustment section 6 was expanded by making the upper wall surface horizontal and gradually expanding the lower wall surface. 7 is a liquid suction pipe.

8 is a liquid suction pipe for adjusting the processing liquid in the upper processing tank 2, and is connected to the suction port 2a. Reference numeral 9 denotes an inclined section, which is provided at the outlet end of the upper processing tank 2 and connected to the header section 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 straighten the fabric etc. that comes up onto the inclined section 9. 13 is a liquid ejection pipe. Reference numeral 14 denotes a 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 branched into two parts, one of which is connected to the reverse direction jet part 12.
The other end is connected to the processing liquid inlet of the header section 10. A passage from the suction port 2a to the treatment liquid injection section 12 via the liquid suction pipe 8, pump 16, and 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 is sucked in from the liquid suction section 4, liquid flow adjustment section 6, and upper treatment tank 2 through the liquid suction pipes 5, 7, and 8, respectively, and at the same time, from the discharge side of the pump 16 via the heat exchanger 17 to an appropriate temperature. adjusted, liquid ejection pipe 13,
15, the reverse direction injection part 12, the inlet in the header part 10, and the liquid injection part 14 each inject the treatment liquid, and the treatment liquid is circulated between the lower treatment tank 1 and the upper treatment tank 2, and the treatment liquid is circulated between the lower treatment tank 1 and the upper treatment tank 2. processing is 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 the fabric etc. progresses in an orderly manner without folding or turbulence, is processed, and transferred to the inlet of the upper treatment tank 2.

Here, the liquid flow adjusting part 6 consisting of a liquid suction part and an enlarged part allows the upper processing tank 2 to be further folded.
progress inward. The degree of accumulation and progress is adjusted by the liquid suction pipe 8, so that the process continues in an orderly manner until reaching the inclined portion 9. Reverse injection part 1
2, the fabric, etc. that rises is sorted and placed on the rollers 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 in the lower processing tank 1, and the processing is carried out during this period.

In the present invention, a liquid flow adjustment part 6 is provided at the connection part between the lower treatment tank 1 and the upper treatment tank 2, but this liquid flow adjustment part 6 is connected to a porous suction part 19 attached to the end of the lower treatment tank 1. The upper surface extends horizontally and the lower surface gradually widens. Therefore, the fabric is decelerated and expanded, and smoothly transferred to the upper treatment tank in a folded state. 20 is an O-ring, 21
is a grooved ring, which allows adjustment without causing deformation of the porous surface even when the porous suction portion 19 expands due to thermal expansion.

Effects of the invention Since the present invention has the above-mentioned 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 coming into contact with the wall surface, and it is possible to avoid overtaking or overtaking. Because it can proceed in an orderly manner without causing any disturbance, this liquid flow treatment device can be used for thin fabrics such as silk fabrics, palis, ponzi, dechine, and specially textured woven and knitted fabrics such as artificial leather, pile, and car seats. It became possible to use it.

In particular, it is important to ensure that thin fabrics such as silk fabrics are kept in a floating state in both the lower and upper treatment tanks when the liquid is medium to almost full. It was possible to transfer the material in an orderly manner without any twisting, and it became possible to perform continuous processing.

Furthermore, a porous suction section is installed at the connection between the lower and upper processing tanks to keep the upper surface horizontal to prevent the fabric from floating up, and to spread the fabric by expanding the lower surface, allowing the fabric to be processed in the upper part. The transition to the tank became smoother. Furthermore, even if the porous suction part expands and contracts due to heat, the expansion and contraction can be absorbed by the O-ring and grooved ring.
It has become possible to smoothly transfer fabrics, etc. at all times.
