Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a treated surface impregnating tank which is advantageous for continuously moist heat treating long length fabrics.

In the process of continuously performing processing such as pretreatment and dyeing on industrially produced long fabrics, the fabrics that are continuously transported are treated with a treatment solution (caustic solution, caustic solution, etc. during pretreatment). There is a liquid impregnation process in which a treatment liquid impregnation tank is arranged to impregnate the fabric (during dyeing process), and a wet heat treatment process in which a steamer is used to continuously process the liquid-impregnated fabric that has passed through this liquid impregnation process. The fabric to be treated is passed through the liquid in the treatment liquid impregnating tank to impregnate it, and then the liquid-impregnated fabric is continuously fed into the steamer and subjected to a wet heat reaction to produce the desired result. It has been proposed to carry out the processing continuously.

However, during the continuous processing of the fabric to be treated as described above, the quality of the processing liquid is changed every predetermined length of the fabric.
It is often required to carry out different or unique processing processes. Specifically, when dyeing a long fabric, for example, it is often required to dye each predetermined length a different color. In the conventional case of performing such different color dyeing, each time the dye solution in the solution tank is changed, the running of the fabric in the solution tank and the steamer is interrupted, or the supply of moist heat in the steamer is interrupted.
After cleaning the inside of the liquid tank and replacing the new dyeing liquid, the running operation of the fabric is continued again, so when the running of the fabric is interrupted and restarted, a change in moisture and heat inside the steamer occurs, which is the cause. There was a problem in that it was impossible to uniformly dye the entire surface of the long fabric. In addition, there is a problem in that when the fabric is interrupted, it is necessary to wait for restart, which reduces productivity.

The present invention has been made in view of the above, and an object of the present invention is to provide a novel treatment liquid impregnating tank that can quickly and effectively replace the liquid in the treatment liquid tank without interrupting the running of the fabric. This is the purpose.

The present invention will be described in detail below based on embodiments shown in the drawings.

Reference numeral 1 denotes a fabric 2f to be impregnated with liquid: an outer wall of a processing liquid tank that can be continuously transferred, and within this outer wall 1 is a movable tank 4 rotatably supported by a support shaft 3; A fixed tank 5 corresponding to the movable tank 4 is provided, and the combination of the movable tank 4 and the fixed tank 5 forms a fabric passage 6 having a substantially V-shaped side surface. Reference numeral 7 denotes a fabric guide roll rotatably provided at the lower 11411 end of the fixed tank 5. Reference numeral 8 denotes a processing liquid supply pipe for constantly injecting a fixed amount of processing liquid into the fabric passage 6, and 9 is a defoaming plate provided near the inlet and outlet of the fabric passage 6. 1o is a fabric guide roll for introducing the fabric into the fabric passage 6 or leading out the fabric from the fabric passage 6, and 11 is a liquid squeezing roll. 12
is a cleaning jaw placed at a suitable location within the outer wall l, and this cleaning jaw 12 cleans the surfaces of the fixed tank 5, the inner surface of the movable tank 4, the processing liquid supply pipe 8, the guide roll 10, the squeezing roll 11, etc. They are installed in large numbers at locations where they can be effectively cleaned. 13 is a cylinder for rotating the movable tank 4.

The above is the structure of the treatment liquid impregnating tank according to this embodiment.
Next, to describe its action, when the piston of the cylinder 13 is pushed out, the movable tank 4 moves to the position shown by the solid line, and the movable tank 4 and the fixed tank 5 form a V-shaped fabric passage 6. Ru. Next, while injecting the processing liquid supplied from the processing liquid supply pipe 8 into the fabric passage 6, the fabric 2 is
be transferred. As the fabric 2 is moved through the fabric passage 6, the processing liquid supplied to the fabric passage 6 is sequentially absorbed into the fabric 2, so that the liquid in the fabric passage 6 is continuously refreshed so that the liquid does not run out. Since the processing liquid is supplied into the fabric passage 6 through the processing liquid supply pipe 8, the fabric 2 is always impregnated with fresh processing liquid, and effective liquid-impregnated processing can be continued.

Next, when changing the treatment liquid impregnation tank, the cylinder 13 is operated without stopping the running of the fabric 2, and the oT
By operating the moving tank 4 as shown by the chain line, the V-shaped fabric passage 6 is opened and the remaining liquid in the 0T1 auxiliary tank 4 is discharged. Since the volume in the fabric passage 6 is set as small as possible without interfering with the transfer of the fabric, the amount of residual liquid to be discharged can be extremely small. Therefore, when cleaning water is jetted from each cleaning tank 12, this cleaning water is sent to the fixed tank 5 and the movable tank 4.
, the guide roll 7, the squeezing roll 11, etc., for effective cleaning in a short period of time. During this cleaning operation, the transfer of the fabric (guiding fabric) 2 is carried out continuously, that is, without stopping the transfer of the fabric, so that the cleaning of the guide rolls 7, 10, squeezing rolls 11, etc. can be completed effectively and quickly. .

After the cleaning of the treatment liquid impregnation tank is completed in this way, the fabric passage 6 is re-formed by closing the movable tank 4, and by supplying new treatment liquid into the fabric passage 6 from the treatment liquid supply pipe 8,
Different liquid impregnating treatments are performed successively.

As described above, the present invention includes a fixed tank 5 provided with a guide roll 7 for fabric, a movable tank 4 having a wall surface that is close to and spaced from the wall of the fixed tank to form a fabric passage 6, and a movable tank 4 that has a fabric passage 6. Tank 4
A cylinder 13 that can be fully tilted and raised, the fixed tank 5 and the movable tank 4
a processing liquid supply means 8 for sequentially supplying the processing liquid into the fabric passage formed by the fixed tank 5 and the movable 4v;
This treatment liquid impregnation tank is characterized by being equipped with a cleaning liquid injection nozzle that sprays cleaning liquid toward the fabric passage forming surface or other guide roll surface of I4. According to this method, the inside of the liquid tank can be effectively and quickly cleaned by opening the movable tank by the operation of the cylinder and continuing the continuous transfer of the long fabric by the spraying action of the cleaning liquid. , it has the advantage of being able to exchange the liquid in the liquid tank.
