Description

Description: BACKGROUND OF THE INVENTION The present invention relates to dyeing, scouring, bleaching, and wet processing while transferring and circulating a rope-like fiber product (fabric) through an annular fabric processing passage by an air flow and a liquid flow in a processing fluid. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an airflow processing apparatus and a processing method for performing processing such as texture processing.

2. Description of the Related Art Conventionally, there has been known an airflow type processing apparatus in which a cloth is transferred by an airflow, and the cloth is moistened and dyed by a treatment liquid. For example, US Serial No. 74 489403 (Japanese Patent Laid-Open Publication No. 51-32885) and DE P314220
0.4 (Japanese Patent Publication No. 63-36385) discloses the technique.

In these known examples, compared with a conventional liquid flow dyeing machine, that is, an apparatus for transferring and dyeing a fabric by a liquid flow, a cloth or the like is transferred by an airflow to obtain an ultra-low bath ratio (bath ratio of 1). : 3 or less), but it has the following difficulties in actual processing, although it is an excellent configuration.

That is, in the former invention of JP-A-51-32885, a treatment liquid is applied to an object to be treated at room temperature through an inert gas (usually air). The method uses a two-stage treatment method in which the dye is fixed by changing the surface conditions and the temperature condition of the treatment solution, and has a disadvantage that the treatment time is long.

Further, in the latter invention of Japanese Patent Publication No. Sho 63-36385, the cloth circulation is started by using a non-inert gas (hot air or steam), and then the temperature is raised to the set temperature at a stretch by using the steam supplied from the supply conduit. Then, the circulation processing is performed for a predetermined time.

However, when steam is used as an air flow for transporting the fabric, dew condensation occurs due to the steam on the inner wall of the can, which falls on the object to be processed, causing spot-like uneven dyeing. There is a problem that the amount of the processing solution increases and the concentration of the chemical solution changes.

Further, in both the former and the latter, since a header section having a drive reel is provided in a circular cross section above the substantially U-shaped processing tank to transfer the fabric as a device having a large vertical head, tension is applied when pulling up the fabric. And wrinkles are generated due to rope wrinkles and overlapping fabrics, and the relax effect cannot be sufficiently exhibited.

To solve some of the difficulties described above, Japanese Patent Publication (Japanese Patent Publication No. 7-30505, Japanese Patent Application No. 4-226)
No. 024) provides a new air-flow type treatment apparatus for rope-shaped textile products (see FIGS. 8 and 9). That is, the transfer pipe 42 and the storage tank 43 are formed horizontally long as a whole, and the inlet of the transfer pipe and the outlet of the storage tank are connected via the header section 44, and the outlet of the transfer pipe is connected to the inlet of the storage tank. An annular fabric processing passage 45 is provided which is connected so as to be inserted into the section. Accordingly, the cloth processing passage 45 is provided with a header section 44 containing a drive reel 46, a processing fluid ejecting section 47 connected to the header section and provided in a horizontal direction, and a transfer section extending horizontally from the processing fluid ejecting section. The pipe 42 is connected to the outlet of the transfer pipe, and the inlet side is a descending section inclined downward, the intermediate section is slightly inclined toward the traveling direction, and the outlet side is connected to the header section so as to be upward. Rising part 48 that bends sharply to
And a stagnation tank 43.

In this apparatus, the cloth and the like are transferred and circulated by the airflow in the annular cloth processing passage, and the heat exchangers 51 and 52 are provided in the airflow circulation passage 49 and the processing liquid circulation passage 50, respectively.
To generate a gas-liquid mixed fluid whose temperature is more accurately controlled,
This gas-liquid mixed fluid is jetted and supplied to a cloth or the like to perform a treatment such as dyeing, and has an extremely low bath ratio (bath ratio of 1: 3).
The following is achieved.

However, the technology shown in Japanese Patent Publication No. 7-30505 is
Since it has a rising part that is bent sharply upward at the outlet of the storage tank and is connected to the header, the head from the bottom of the storage tank to the header is large, and the tension is applied to the cloth to cause rope wrinkling. However, there were difficulties such as the pushing wrinkles in the accumulation tank being fixed. Also, the fabric is vertically moved from 120 to 150 by a reel or a roll incorporated in the header.
After turning the direction, the fluid is fed into the transfer passage extending in the substantially horizontal direction by the jetting force of the fluid. there were. Further, when both the fabric propulsion force by the fluid from the processing fluid ejecting unit and the fabric propulsion force by the drive reel or roll are used, there is a problem that a difference occurs between the two and it is difficult to make the transfer speed of the fabric coincide. Was done. As an example in which a reel or a roll is omitted, Japanese Patent Application No. 6-051591 (JP-A-7-268763)
No.) has been proposed.

Further, in the above-described conventional airflow processing machine, a gas-liquid mixed fluid is generated in advance by a fluid mixing section (see FIG. 9), and this gas-liquid mixed fluid is jetted and supplied from a processing fluid jetting section to a cloth or the like and transferred. It circulates and performs processing such as dyeing. As described above, since the processing liquid is mixed and sprayed in the airflow by providing the fluid mixing section, an appropriate mixed fluid according to the basis weight of the object to be processed cannot be obtained, and the target of the fabric that can be processed is limited. was there. An example in which an airflow injection unit and a liquid flow injection unit are provided in the processing fluid processing unit has been proposed as Japanese Patent Application No. 6-270798, but these injection units are fixed and the injection pressure of the airflow and the liquid flow is reduced. Each could not be changed separately.

Further, in the conventional airflow type processing apparatus, when the processing such as dyeing is completed, at least about 80
° C, and then the processing liquid stored in the bottom of the storage tank is drained.In the cooling step, a mixed fluid of the processing liquid and the gas is continuously jetted from the processing fluid jetting unit, and the mixed fluid is cooled. Had been cooled using. Therefore, cooling water is indispensable, and the cooling time tends to be prolonged because of indirect cooling. Also, when the temperature of the processing fluid is lowered to some extent, impurities (oligomer-olig) eluted from the processing cloth are obtained.
omer) may adhere to the fabric again, and furthermore, the treatment liquid is sprayed on the fabric in the cooling step, so that the calorie of the fabric is maintained at a relatively high level, and the cooling time is prolonged in combination with indirect cooling by cooling water. There was a problem of becoming.

Among the inventors of the present invention, Ishimaru has proposed a method using latent heat of vaporization without using cooling water as an invention to improve this point (Japanese Patent Application No. Hei 7-105210).
issue).

In addition, among the inventors of the present application, Ishimaru and Takigawa provided an outlet portion of the storage tank at a low position as a sphere so as to improve the annular fabric processing passage and not apply tension to the fabric, and set an inlet portion of the transfer pipe substantially vertical. There has been proposed an airflow type processing apparatus which is connected to an outlet of the storage tank and has an annular processing passage having a reel or a roll at the outlet (Japanese Patent Application No. 7-218434). Also, Nomura has proposed a gas-liquid integrated type nozzle structure (Japanese Patent Application No. 7-185331). Ishimaru, Takigawa and Nomura as the inventor of the present application have improved the overall structure of the airflow processing apparatus, and can appropriately transfer and circulate the cloth even with or without a header or reel. Was found.

SUMMARY OF THE INVENTION The present invention solves the drawbacks of the conventional example as described above, adopts a novel configuration, and provides a comprehensively combined apparatus and method so that the cooling step and the drying step in the processing step can be appropriately controlled. .

DISCLOSURE OF THE INVENTION One object of the present invention is to transfer and circulate a fabric by an air flow and a liquid flow from a processing fluid ejecting unit without or with a reel or a roll, and in particular, at a position lower than an inlet of a storage tank. An object of the present invention is to provide an apparatus for air-flow-type treatment of rope-like fiber products and a method for treating the same, which enable a fabric to be pulled up smoothly and in a short distance without tension from an outlet portion of a storage tank provided in the apparatus.

Another object of the present invention is to transfer and circulate the fabric by injecting and supplying a mixed fluid of an air stream and a liquid stream from a processing fluid ejecting unit at an outlet of a storage tank provided at a low position, so that tension is not applied to the fabric. An air-flow treatment device for rope-like fiber products with an extremely low bath ratio that prevents rope wrinkles, vertical elongation, and does not cause spots, threads, slashes, etc., and has no operational troubles such as the generation of cloth mottle. And to provide a processing method therefor.

Still another object of the present invention is to process from a light-weight synthetic fiber to a heavy-weight fiber according to the processing purpose, to broaden the object of the cloth, and to mix the liquid flow and the air flow according to the type and the weight of the cloth. It is an object of the present invention to provide an apparatus for air-flow-type processing of a rope-shaped textile product having a nozzle provided with a processing fluid jetting section capable of adjusting the pressure and obtaining an appropriate propulsive force, and a processing method thereof.

Still another object of the present invention is to achieve energy saving by a cooling effect by latent heat of vaporization without relying on cooling water in a cooling step, shorten a cooling time, prevent adhesion of an oligomer, and perform a series of processes until drying. An object of the present invention is to provide an airflow type processing apparatus and a processing method thereof.

According to the present invention, the transfer passage and the storage tank are connected at both ends to form an annular fabric processing passage. The transfer passage is provided with a processing fluid ejecting portion at an inlet portion and is bent so as to extend substantially straight, and the outlet portion is a storage tank. Are inserted and connected in the entrance portion of the. The outlet of the storage tank is lower than the position of the inlet, and is inclined so as to gradually descend in the traveling direction of the fabric, and the end of the outlet is bent upward to be substantially spherical, and the inlet of the transfer passage is formed. Is linked to The height of the processing fluid ejecting portion provided at the entrance of the transfer passage from the ground portion was reduced, and it was difficult for the tension to be applied when the fabric was pulled up from the floating state in the accumulation tank. A porous nest plate is provided at the bottom of the storage tank to form a double bottom, and the floating cloth is well drained, and a liquid storage section for storing separated water is provided.

As described above, the cloth is transferred from the accumulation tank to the transfer passage for a short distance so as to be sucked into the processing fluid ejection unit at a low position, and is lifted up. No rubbing or rubbing around. Also, when a reel or a roll is provided, the direction can be smoothly changed to the processing fluid ejecting section, thereby ensuring the transfer.

The processing fluid injection unit is provided with a liquid flow injection unit and an air flow injection unit, and the air flow and the liquid flow are respectively injected and supplied at different injection angles, and the gaps between the respective injection nozzles are adjusted.
The adjustment of the injection pressure by the mixed fluid of the air flow and the liquid flow, and the enhancement and optimization of the propulsive force by the injection are performed, so that the processing fluid can be appropriately adjusted according to the processing purpose, the type of fabric, and the basis weight.

The liquid jet unit is connected to a processing liquid circulation path from the bottom of the storage tank to the liquid jet unit via a pump, a heat exchanger, and a control valve, and the air jet unit is blown from the gas phase of the storage tank to the blower. And an airflow circuit leading to the airflow injection unit via the control valve. Therefore, the mixed fluid is adjusted according to the type and basis weight of the cloth as the object to be processed, and the ratio of gas-liquid mixing can be adjusted according to the processing purpose. For example, in a case where a synthetic fiber having a light weight such as polyester is used to obtain a relaxing effect or an untwisting effect, the air flow is increased and the air is circulated promptly and smoothly. In the case of performing short-time dyeing or fir processing (fibril processing), by controlling the ratio of the liquid flow to be large, it is possible to realize a processing method in which transfer is smooth and processing unevenness does not occur.

In the storage tank, the treatment liquid contained in the fabric falls and is separated through the porous nest plate formed on the double bottom, so that the water content is reduced, the weight of the fabric is reduced, and the fabric is suspended in the gas phase. And when it is pulled up by the ejection force of the processing fluid ejection unit at the upstream end of the transfer passage, it can be smoothly transferred with little weight and little tension. Further, since the distance over which the cloth is pulled up is short, the cloth does not extend in the vertical direction and the rope does not wrinkle.

In the present invention, when a drive reel or a roll is not provided at the outlet portion of the storage tank, the fabric does not come into contact with the thread, and there is no occurrence of threading, attrition, or slippage due to frictional resistance. When the drive reel or roll is provided at the outlet of the accumulation tank, the direction of the cloth is smoothly changed from the accumulation tank to the transfer passage, and the thread and the hit do not occur. Even at the outlet side of the transfer passage, the transfer can be smoothly performed to the accumulation tank along the passage, and the cloth can be tangled and tension is not applied, so that a good texture treatment can be performed.

The processing liquid separated in the storage tank is circulated through the processing liquid circulation path from the liquid storage section at the bottom, but the processing liquid can be smoothly circulated without surging by the pump due to the presence of the liquid storage section. I have.

In the treatment of the fabric, first, the fabric is charged from an input port provided at an outlet portion of the storage tank, and is conveyed from the transfer passage to the storage tank by an air current, and both ends are connected to form a rope and circulate through the annular processing passage. I do. Thereafter, in the process of raising the temperature of the processing fluid supplied from the processing fluid ejecting unit and maintaining the temperature at a constant temperature, dyeing or other processing is performed using a mixed fluid of an air stream and a liquid stream. The pressure was controlled by evaporating latent heat while gradually reducing the pressure and repeating the pressurization and the depressurization, so that drying could be further performed.

Therefore, a high-temperature drain valve connected to the accumulation tank, a pressure sensor for detecting the pressure in the airflow processing device, a cooling control pressure control valve connected to the airflow processing device, and a signal from the pressure sensor are used. And a controller for controlling the high-temperature drain valve and the cooling control pressure control valve.

Therefore, in the cooling step, the cloth is circulated by injecting only the gas without injecting the processing liquid from the processing fluid injection unit, and the cloth is cooled by the latent heat of vaporization by the pressure control of the circulating airflow, so that the cooling water is not used. The fabric can be cooled directly and efficiently. Further, since the treatment is mainly performed by air flow, the amount of the treatment liquid impregnated in the fabric is small, the amount of heat accumulated in the fabric is small, and the cooling time can be greatly reduced in combination with efficient cooling by vaporization latent heat by pressure control.

Further, before entering the drying step, a circulation process is performed under a predetermined high pressure for a certain period of time, and then deaeration is performed at once, and the pressure is returned to normal pressure. In addition, as a drying method, when the fabric can be transferred only by the airflow, the drying process can be realized by sucking and exhausting the outside air, and a consistent process from the introduction of the fabric to the treatment and the drying can be performed.

Since the storage tank has a high inlet portion and a low outlet portion and is located at a low position from the ground where the apparatus is installed, the distance of the fabric pulled up by the processing fluid jetting portion is short, and the length of the fabric extends in the vertical direction and rope wrinkles occur. Or not. If no drive reels or rolls are provided, there is no contact with these, and there is no eye contact, no threading, no attrition, and the like.

As a nozzle of the processing fluid injection unit, an appropriate jet is performed by an airflow injection unit communicating with the airflow supply pipe connected to the airflow circulation path, and a liquid flow injection unit communicating with the liquid flow supply pipe connected to the liquidflow circulation path. The air flow and the liquid flow are adjusted at an angle to simultaneously jet and supply the cloth. During this injection,
The gap between the nozzles can be changed by moving the center sliding cylinder and the cylindrical guide or the trumpet-shaped guide, and the propulsion force can be changed or the wettability can be appropriately adjusted according to the type and basis weight of the fabric. Adjustable.

In the present invention, the cloth is transported and processed by the mixed fluid of the airflow and the liquid flow in the airflow type processing apparatus, so that the wrinkle position always moves, so that the rope wrinkles are not fixed, and the pulling tension is reduced to increase the cloth transfer speed. As a result, productivity can be improved by shortening the processing time. Further, the control unit 17 controls the amount of the fluid jetted from the airflow jetting unit 4 and the processing liquid jetting unit 5 according to the type of the fabric, for example, by using different fibers such as polyester fiber or wool and the difference in basis weight. By adjusting the opening degree of 10, 15 it is possible to generate an appropriate mixed fluid. Further, when a relaxing effect or an untwisting effect is to be obtained with polyester depending on the processing purpose, the air flow is increased and the circulation is performed promptly and smoothly. In the case of performing short-time dyeing or fir processing (fibrillation), adjustment can be made to increase the ratio of the liquid flow.

In the present invention, since the sliding cylinder provided in the nozzle case is variable, the gap between the nozzles of the air flow and the liquid flow introduced into each room from the air flow supply pipe and the liquid flow supply pipe is changed, and the fiber as the object to be treated is changed. The injection propulsion force can be appropriately selected according to the type and the basis weight of the fuel. Since the sliding cylinder slides through the flange of the nozzle case, the gap between the nozzles (a) and (b) can be changed individually or both, and the cylindrical guide and / or the flapper guide can be changed. It can slide. Also, fix the cylindrical guide to the nozzle case,
The nozzle case can be easily mounted, and the nozzle gap can be adjusted by sliding the sliding cylinder and the flared guide. In addition, the center ring is fixed at a fixed position by an adjusting ring so that the adjustment can be more easily performed.

In the nozzle of the present invention, the adjusting ring is provided on the sliding cylinder to regulate the fixed position of the sliding cylinder.
The gap of (b) can always be set to be constant, and a constant nozzle setting can be easily realized for processing the same type of fabric. Furthermore, the nozzle (a) for airflow injection is placed with the center axis of the sliding cylinder interposed.
The spray angle is set to 15 to 50 degrees, and the nozzle (b) for liquid flow jetting is set to an injection angle of 5 to 30 degrees with respect to the center axis of the sliding cylinder, so that the propulsive force and the wetting on the cloth can be accurately achieved. In addition, by providing an injection angle such that the focal position of the airflow jet from the nozzle (a) coincides with the focal position of the liquid jet flow from the nozzle (b), efficient jetting power can be obtained.
Furthermore, the positions of the air flow jetting unit and the liquid flow jetting unit can be interchanged to obtain a mixed fluid according to the fiber, smooth transfer and circulation are possible, and the quality can be further improved.

The cloth 20 is transferred in the transfer passage 2 by the jet force of the airflow and the liquid flow, reaches the intermediate portion from the entrance side of the storage tank 3 together with the sliding down action by its own weight, and is stored in the intermediate portion. It becomes a relaxed state, is gradually moved horizontally, is pushed out from the middle part of the storage tank 3 to the outlet side, and is pulled up by the processing fluid jet 6. On the other hand, surplus processing liquid is dropped from the porous nest 8 at the bottom of the storage tank 3 and stored at the bottom.
The processing liquid is collected from the processing liquid circulation path 16 and returned to the processing liquid injection section 6 again.

This has the effect of preventing re-contamination. In the above embodiment, it is also possible to perform cooling by lowering the pressure without performing high-temperature drainage before the cooling step, and in this case, some cooling time is required as compared with the case where the high-temperature drainage precedes. , Oligomers etc. can be prevented from re-adhering,
The calorific value of the fabric can be reduced.

In the present invention, the drying after the wet treatment of the fabric can be continuously performed. For example, pressurize the inside of the storage tank 3 to 3K,
After circulating for about 5 minutes, exhaust (about 2K), pressurize again, and repeat.

Further, as shown in FIG.
If a heat exchanger 35 is provided and external air is taken in, fresh air can be introduced into the airflow circulation path 11 through the filter 36 and the valve 37. The process can be realized. In this case, blower 9 is 37
It can be performed sufficiently with about kw.
