Description

  The present invention relates to a liquid flow processing apparatus used for performing processing such as dyeing processing, texture processing, weight loss processing, etc., on a textile product such as fabric, and in particular, liquid flow processing suitable for dyeing processing. It relates to the device.

  A general liquid flow processing apparatus 60 will be described with reference to FIGS. 6 and 7. A main part of the liquid flow processing apparatus 60 is a staying part in which a fabric 61 connected in an endless manner is in a meandering state and temporarily stays with a processing liquid 62. 63 and a transfer pipe 66 that is connected between the front portion 64 and the rear portion 65 of the staying portion 63 and transfers the fabric 61 together with the treatment liquid 62. The front part 64 of the stay part 63 is provided with a jet nozzle 67 for jetting the treatment liquid, and the treatment liquid 62 jetted from the jet nozzle 67 is pulled up from the state where it stays in a meandering manner in the stay part 63. Together with 61, the jet 61 flows through the transfer pipe 66, and the fabric 61 is transferred to the rear portion 65 of the staying portion 63. The transfer pipe 66 is arranged so that the downstream end portion 68 has a substantially inverted J shape and enters the inside of the rear portion 65 of the retention portion 63, and the fabric 61 transferred together with the treatment liquid 62 is contained in the retention portion 63. And is pushed into the rear part of the fabric 61 staying in a meandering manner together with the jet. When the fabric 61 is in the liquid flow processing apparatus 60, it is always ready for dyeing and other processing, but the main processing of the fabric 61 is to move the fabric 61 together with the processing liquid from the rear portion 65 of the retention portion 63 to the front portion 64. While being immersed in the treatment liquid 62, it is performed. And in order to repeat this process, the fabric 61 is pulled up from the staying state to the front part 64 of the staying part 63, moves to the transfer pipe 66 and circulates.

  In the above-described prior art, the portion of the fabric 61 staying in the meandering state is pressed at the rear portion by the portion of the fabric 61 that is vigorously fed together with the treatment liquid 62 from the transfer pipe 66. In addition, since the bottom 69 of the staying part 63 is inclined downward in order to encourage the cloth 61 to move forward, the flow of the treatment liquid 62 is strengthened at the rear part of the staying part 63. For this reason, the pressure with respect to the fabric 61 is further strengthened, and the fabric 61 staying in a meandering shape is entangled in the front and rear and up and down and twisted. Such a situation has an adverse effect such as damaging the texture of the fabric 61. In order to alleviate the situation with respect to the fabric 61, the treatment liquid 62 is decreased and the flow of the treatment liquid 62 is made gentle. It has been tried, but it is not an effective measure.

  Therefore, when pulling up the fabric 61 that is entangled with the retention portion 63 and stays with the treatment liquid 62, an excessive tensile force is applied to the fabric 61 so that the fabric 61 does not cause vertical warp or the like. It has also been practiced to provide a draining porous nest plate having a substantially U shape with an upward slope on the downstream side, and pull up the fabric along the porous nest plate (see, for example, Patent Document 1).

  Separately, the end of the transfer pipe is arranged at the bottom of the rear part of the fabric retention section so that the treatment liquid exists over the entire length of the fabric retention section, and the fabric entering the fabric retention section from the transfer pipe is processed. There is a liquid flow processing device that is fed into the liquid. According to this liquid flow type processing apparatus, unlike the technique disclosed in Patent Document 1, the cloth is not sent out vigorously from the end of the transfer pipe to the cloth staying part together with the jet flow, and the cloth sent in together with the treatment liquid. Does not appear to press on the rear part of the fabric that stays in a serpentine shape (see, for example, Patent Document 2).

On the other hand, a method of discharging the fabric 61 from the liquid-flow processing device 60 after a predetermined time for processing the fabric is as follows. As shown in FIG. Generally, a method of discharging the processed fabric from the processing reel 52 to the outside of the processing apparatus. If the rotation speed of the discharge reel 52 is increased, the discharge time of the processed fabric is increased accordingly, but there is a limit to its speeding up. Therefore, although not shown, Patent Document 3 discloses a technique for increasing the speed at which the treated fabric is discharged (unloaded) out of the processing apparatus. The technique is to carry out the treated fabric together with the treatment liquid by ejecting the treatment liquid into the cloth carry-out pipe at a high speed.
Japanese Patent Laid-Open No. 10-140462 Japanese Patent Laid-Open No. 01-139659 JP-A-60-199965

  The upwardly inclined substantially U-shaped porous nest plate disclosed in Patent Document 1 is designed to narrow the space with the inner wall of the treatment layer as it goes upward along the inclination (see Japanese Patent Publication; FIGS. 2 to 3). ). The fabric that is pulled up along the gradually narrowed substantially U-shaped perforated nest plate is smoothly formed into a rope shape, and the pulling force of the fabric is reduced by running out of the liquid, and the effect of spreading the fabric is shown. Has been. However, when the fabric is pulled up from the treatment liquid, the speed of the fabric guided to the porous nest plate becomes high, so that the influence of the frictional force on the surface of the porous nest plate and the numerous holes is not negligible. Become. For this reason, there is no possibility of the fabric becoming defective in quality such as flattening, rubbing, and shaking.

  Further, as disclosed in Patent Document 2, in the liquid flow type processing apparatus in which the fabric entering the fabric retention portion from the transfer pipe is fed into the processing liquid, the fabric is fed from the end of the transfer pipe to the processing liquid. At the same time, it does not seem to be ejected vigorously into the space above the treatment liquid surface of the fabric retention part, but the cloth flows into the treatment liquid in the fabric retention part like a fountain in a jet state together with the treatment liquid. The fabric placed in such a situation has a fear that the flowing direction is not fixed and is entangled in the front, rear, top and bottom.

  On the other hand, in the technology related to high-speed carry-out of the treated fabric disclosed in Patent Document 3, it is disclosed that the treated fabric is carried out at a high speed of 200 to 300 m / min by the jet flow from the liquid ejecting unit. . However, in some cases, a substantially stationary fabric entangled in the form of a dumpling is suddenly pulled up at the front portion of the fabric retention portion, and the fabric is pulled up at the above-mentioned high speed, and there are concerns about problems such as damage to the fabric. In addition, since the processing liquid is used as a jet flow, there is a problem that sufficient care must be taken in handling the high-temperature processing liquid discharged as a jet flow outside the liquid flow processing apparatus.

  The present invention has been made paying attention to such problems, and the object of the present invention is to suppress the occurrence of problems such as tangling, twisting, and entanglement of the fabric in the process of liquid flow processing. It is another object of the present invention to provide a liquid flow processing apparatus capable of discharging a treated fabric out of the apparatus at an appropriate speed.

  In order to solve the above problem, the invention of the liquid flow processing apparatus according to claim 1 is provided at a front end of a horizontally long cylindrical retaining portion for temporarily retaining a fiber product connected endlessly, and the retaining portion. A textile product pulling section, a direction changing section of the textile product provided at the front end of the textile product pulling section, and a transfer pipe connected to the direction changing section and the rear end of the staying section. In the liquid flow type processing apparatus for processing by circulating the fiber product in one direction together with the processing liquid in the circulation path, the front part of the staying part forms an enlarged diameter part. . As used herein, “textile product” includes fabric or other fibrous materials.

According to a second aspect of the present invention, in the liquid flow processing apparatus according to the first aspect, the staying portion and the enlarged diameter portion are hollow cylindrical bodies.
According to a third aspect of the present invention, in the liquid-flow processing apparatus according to the first or second aspect, the bottom of the enlarged diameter portion is located lower than the bottom of the staying portion other than the enlarged diameter portion. It is characterized by.

According to a fourth aspect of the present invention, in the liquid-flow processing apparatus according to the second or third aspect, the enlarged diameter portion and the staying portion are substantially coaxial hollow cylindrical bodies. .
According to a fifth aspect of the present invention, in the liquid-flow processing apparatus according to any one of the first to fourth aspects, the direction changing portion is provided with a textile product entry / exit portion, and the entry / exit portion thereof. Is provided with a flush water overflow portion and a discharge pipe for discharging the textile product downward together with the wash water overflowing and falling from the overflow portion.

  The invention according to claim 6 is the liquid flow processing apparatus according to any one of claims 1 to 5, wherein the transfer pipe connected to the rear end portion of the staying portion is in the vicinity of the connecting portion. The diameter is increased in a taper shape.

  The invention according to claim 7 is the liquid-flow processing apparatus according to claim 6, wherein the transfer pipe connected to the rear end portion of the direction changing portion and the staying portion is turned in two places, The diameter of the staying portion is increased on the upstream side of the direction changing portion on the rear end side, and the tapered diameter is increased while maintaining the expanded diameter. It is.

(Function)
According to the present invention, the fiber product that is meandering with the treatment liquid in the staying portion and sent forward is in a slightly entangled or entangled state, but has reached a diameter-expanded portion that is deeper and wider. Even if the fiber product is pressed against the wall surface of the enlarged diameter portion, the force is loose and the upper and lower overlaps are also loosened, so that the fiber product is loosened and floats in the treatment liquid. Therefore, the tensile force that pulls up the textile product is relaxed. Further, since the tensile force is relieved in this way, when the treated textile product is discharged out of the apparatus, the textile product can be drawn into the washing water that overflows and falls at the entrance and exit. Furthermore, the fiber product that is transferred to the rear end of the staying portion as a jet along with the processing liquid in the transfer tube reduces the transfer speed at the portion where the transfer tube expands in a taper shape. The momentum that flows into is eased. Therefore, the degree of pressure when the fiber product is fed into the rear part of the fiber product staying in a meandering manner in the staying portion is reduced.

  According to the present invention, the tensile force for pulling up the fiber product is alleviated, so that the fiber product that receives an excessive tensile force while circulating in the processing apparatus falls into a defective quality such as flattening, rubbing, and blurring. Unlike the above, it is possible to provide a treated fiber product having a good texture.

Hereinafter, an embodiment of a liquid flow dyeing apparatus for dyeing a fabric embodying the present invention will be described with reference to FIGS. FIG. 1 is a front view schematically illustrating the entire liquid dyeing apparatus of the present invention, and FIG. 2 is a plan view schematically illustrating a part of the liquid dyeing apparatus. FIG. 3 is a front view schematically showing a state in which the treated fabric is discharged, and FIGS. 4A and 4B are partial cross-sectional details showing the structure and operation of the portion indicated by symbol A in FIG. FIG. In addition, in the part of the same structure as a prior art, it shall explain using the same code | symbol.

  As shown in FIG. 1, the round pipe-shaped staying portion 63 is arranged in a horizontally long shape having a slight downward slope (for example, 1/100), and spreads in the front portion (downstream) in the direction in which the fabric 61 flows along with the treatment liquid 62. A diameter portion 2 is formed, and at the front end of the diameter-expanded portion 2, a fabric pull-up portion 3, a fabric direction changing portion 4, and a fabric entry / exit portion 5 are connected and arranged in this order. A processing liquid ejecting section 14 is provided below the direction changing section 4, and an end of the transfer pipe 66 is disposed inside the processing liquid ejecting section 14, and a flow of the processing liquid 62 is formed in the vicinity of the end. Therefore, an injection nozzle 67 for injecting the treatment liquid 62 is provided. The direction of the transfer pipe 66 is changed at two places, and the downstream end is connected to the rear end 6 of the staying part 63 with its opening edge inserted. At this time, as shown in the drawing, the transfer pipe 66 is bent at the direction changing portion 12 and connected to the rear end portion 6 of the staying portion 63, but the transfer pipe diameter on the upstream side of the direction changing portion 12 is increased. It is connected to the rear end portion 6 of the staying portion 63 through a tapered portion 11 that is expanded in diameter by the portion 13 and is changed in direction by the direction changing portion 12 while maintaining its diameter.

  The hollow cylindrical enlarged diameter portion 2 is coupled via the tapered portion 21 so as to be coaxial with the enlarged diameter portion 2 and the staying portion 63 other than the tapered portion 21, and the bottom plate is positioned lower than the bottom of the staying portion 63. A perforated plate 7 is provided. The fabric pull-up portion 3 provided at the front end of the enlarged-diameter portion 2 is formed in a tapered hollow cylinder that is tapered obliquely upward. A treatment liquid reservoir 16 is provided at the bottom of the enlarged diameter portion 2, and the treatment liquid reservoir 16 is connected to the pump 8 via a treatment liquid return pipe 17. A heat exchanger is connected to the pump 8, and the heat exchanger 9 is connected to the processing liquid ejection unit 14 via a processing liquid delivery pipe 15.

  A guide roll 31 is provided inside the entrance / exit portion 5, and as shown in FIG. 4, a wash water overflow portion 43 in which the wash water stored in the storage portion 45 overflows is provided below the entrance / exit portion 5. Is formed. A discharge pipe 44 is formed through the bottom of the overflow section 43 at the bottom of the overflow section 43, and an end of the discharge pipe 44 enters the interior of the overflow section 43 by the height that forms the storage section 45. . An introduction pipe 41 for introducing cleaning water is connected to the overflow part 43 via an on-off valve 42. A storage box 32 for storing the discharged fabric 61 is installed below the discharge pipe 44, and a perforated plate 33 for separating the liquid from the fabric 61 is provided at the bottom of the storage box 32. Is formed with a drain port 34 for draining the mixed solution of the treatment liquid and the washing water.

(Dyeing process of fabric)
A process in which a fabric is dyed by the liquid flow dyeing apparatus of this embodiment will be described. After the fabric 61 put into the apparatus is connected endlessly, it is transferred into the transfer pipe 66 together with the processing liquid 62 injected from the injection nozzle 67 and reaches the rear end portion 6 of the staying portion 63. The processing liquid 62 sprayed from the spray nozzle 67 is sucked by the pump 8 from the processing liquid reservoir 16 through the processing liquid return pipe 17 and further fed into the heat exchanger 9, heated by the heat exchanger 9, and then processed. The liquid is supplied to the processing liquid ejecting section 14 via the liquid delivery pipe 15. The fabric 61 transferred together with the treatment liquid 62 starts to slow down in the transfer pipe diameter-expanding portion 13, and further decreases the flow rate while passing through the tapered portion 11 and reaching the rear end portion 6 of the staying portion 63. Then, it flows into the staying part 63 so as to float in the processing liquid 62 flowing into the laminar flow state without being jetted together with the processing liquid 62 to the rear end part 6 of the staying part 63. The fabric 61 in the staying part 63 is fed forward in a meandering manner while the processing liquid 62 drifts so as to drift, but when the diameter reaches the enlarged part 2 through the tapered part 21, the enlarged part 2 Since the depth of the treatment liquid 62 is increased, the treatment liquid 62 is also spread left and right, so that what is packed in the front and back and loosely pressed is loosened and floated, and can be pulled up with a weak tensile force.

  In the liquid flow type dyeing apparatus 1 of the present embodiment for dyeing the fabric, the treatment liquid 62 in the staying portion 63 needs to be maintained at 130 to 140 ° C., and thus becomes a sealed container during the dyeing treatment process. The atmospheric pressure in the retention part 63 is rising to 0.5 Mpa. Therefore, the staying part 63 must have a structure in which the enlarged diameter part 2 can sufficiently withstand the internal pressure, and the staying part 63 and the enlarged diameter part 2 are formed in a hollow cylindrical shape in order to cope with the internal pressure. is there.

(Cloth discharge process)
Next, the process of discharging the processed fabric 61 out of the apparatus will be described. As shown in FIG. 4A, the lid 46 blocks the overflow portion 43 during the processing step of the fabric 61. At this time, since the lid 46 receives the internal pressure in the apparatus and is pressed against the packing 48, the pressure in the apparatus does not decrease. Next, as shown in FIG. 4B, the lid 46 can be rotated inward with the shaft 47 as a rotation axis and opened in a state in which the pressure in the apparatus is reduced to atmospheric pressure. Therefore, after the fabric 61 guided by the guide roll 31 is passed through the discharge pipe 44, the on-off valve 42 is opened and the cleaning water is introduced into the overflow portion 43. The cleaning water is then stored in the storage portion 45 of the overflow portion 43. The surface is raised and eventually reaches the height of the end of the discharge pipe 44 and overflows. The overflowing wash water flows downward in the discharge pipe 44, and the fabric 61 previously disposed in the discharge pipe 44 is drawn into the wash water that flows down and travels through the discharge pipe 44 together with the wash water. It is discharged out of 44 and stored in the storage box 32. The mixed liquid of the treatment liquid and the washing water contained in the accommodated fabric 61 is separated by the perforated plate 33 and discharged from the drain outlet 34 to the outside.

  Such a discharge method of the fabric 61 using the washing water flowing down the discharge pipe 44 is possible if the discharge force is stronger than the force that pulls up the fabric 61 from the staying portion 63, but the diameter-enlarged portion of the present embodiment. In FIG. 2, the fabric 61 is in a floating state, and the tensile force that pulls up the fabric 61 is weak.

According to the liquid flow type dyeing apparatus of the above embodiment, the following effects can be obtained.
(1) In the above embodiment, since the enlarged diameter portion 2 is formed at the front portion of the retention portion 63, the fabric 61 that has flowed in the meandering state together with the treatment liquid 62 in the retention portion 63 is loosened by the enlarged diameter portion 2. This floats in the processing liquid 62. Therefore, the tensile force for pulling up the fabric 61 may be small, and the fabric 61 can be pulled up while maintaining the texture of the fabric 61 and the like.

  (2) In the above embodiment, since the staying portion 63 and the enlarged diameter portion 2 are hollow cylindrical bodies, the enlarged diameter portion 2 having a larger diameter is different from the fact that the staying portion 63 of the prior art is formed with the same diameter. Even if formed, a liquid flow type dyeing apparatus that can withstand internal pressure can be provided.

  (3) In the above embodiment, since the bottom of the enlarged diameter portion 2 is made lower than the bottom of the staying portion 63 other than the enlarged diameter portion 2, the flow of the processing liquid 62 that has settled on the enlarged diameter portion 2 becomes slower. The unraveling action of the fabric can be enhanced.

  (4) In the above embodiment, since the enlarged portion 2, the enlarged portion 2 and the staying portion 63 other than the tapered portion 21 are substantially coaxial hollow cylindrical bodies, a high internal pressure can be obtained without using a particularly strong structure. An endurable liquid dyeing device can be provided.

  (5) In the above embodiment, as a method of discharging the treated fabric 61 to the outside of the apparatus, the fabric 61 is drawn into the flow when the washing water overflows and falls. Not only has the speed of discharge been realized, it is also possible to wash away the treatment liquid with washing water.

  (6) In the above embodiment, since the transfer pipe 66 is connected to the rear end portion 6 of the stay part 63 by the taper part 11 whose diameter is increased in a taper shape, the cloth that has flowed through the transfer pipe 66 in a jet state together with the treatment liquid 62. 61 can flow in without dropping its flow velocity and jetting into the staying portion 63.

  (7) In the above-described embodiment, since the diameter of the transfer pipe 66 is expanded and the diameter is maintained, the transfer pipe 66 is connected to the tapered portion 11, so that the fabric 61 whose flow velocity has been reduced in advance further reduces the flow velocity at the tapered portion 11. . Therefore, the fabric 61 can flow into the stay part 63 so as to float up in the processing liquid 62 that flows gently.

In addition, you may change the said embodiment as follows.
Although the staying part 63 is arranged horizontally long with a slight downward slope, it may be arranged horizontally horizontally.
-About the connection to the rear-end part 6 of the retention part 63 of the transfer pipe 66, it connects with the taper part 11, expanding the diameter by the transfer pipe enlarged diameter part 13, and maintaining the diameter, and connects via the taper part 11 However, only the tapered portion 11 may be formed without increasing the diameter by the transfer pipe expanding portion 13, and the connection may be made via the tapered portion 11.
In the above-described embodiment, the present invention is embodied in a liquid-type dyeing apparatus for dyeing the fabric 61. However, the present invention is not limited to a fabric, and the yarn or other fibrous material is connected endlessly as a fiber product to be processed by immersing it in a liquid. It can also be applied as a liquid flow processing apparatus.
In the above-described embodiment, the present invention is embodied in a liquid flow type dyeing apparatus that dyes the fabric 61. However, the present invention is not limited to a dyeing process, and may be applied as a liquid flow type processing apparatus that performs a textured and weight reduction process for a cloth.
