In this processing apparatus, a processing liquid such as a dyeing liquid is mixed and supplied in a mist state in an air flow for circulating and moving the textile product in a processing tank, and a gas-liquid mixed fluid composed of the processing liquid and the air flow is supplied to the textile product. By performing a treatment such as dyeing while circulating and moving it in the treatment tank, an extremely low bath ratio is realized, and a tensionless relaxation treatment is performed to shorten the treatment time. .

[0004]

By the way, in the above-described conventional processing apparatus, when the processing such as dyeing is completed, all the processing solution stored in the bottom of the processing tank is drained. After this drainage, by supplying the cleaning liquid into the treatment tank, as in the case of the dyeing treatment described above, a gas-liquid mixed fluid of the cleaning liquid and the airflow is jetted to the textile product and circulated in the treatment tank. While doing so, the cleaning process is performed. As a result, after the operation of the apparatus is stopped in the processing step and the liquid is drained, as a post-step of the processing step, the cleaning liquid must be supplied into the processing tank to restart the operation of the apparatus. When the processing step and the cleaning step are separately provided in this way, there is a problem that the operating efficiency of the apparatus is poor and the short-time processing becomes difficult.

Therefore, the present invention has been proposed to solve the above problems, and an object of the present invention is to reduce the man-hours to improve the operation efficiency and realize the short-time processing. To provide a cleaning method and a cleaning device.

[0006]

As a technical means for achieving the above object, the method of the present invention comprises a transfer passage for transferring a rope-shaped fiber product in a substantially straight state and a retention path for transferring the fiber product in a meandering state. A rope-shaped fiber product in which the endless fiber product is housed and arranged in an annular processing tank formed by connecting with a passage, and a treatment liquid is supplied from the upstream end of the transfer passage to the fiber product for circulation treatment. In the processing device, when the processing liquid is drained , the cleaning liquid is supplied upstream of the transfer passage.
Injected supplied from the edge is injected toward the textile, the cleaning solution to the textile while replacing the processing solution in the cleaning solution
It characterized in that as washing with.

Further, the apparatus of the present invention is formed by connecting a transfer passage for transferring the rope-like fiber product in a substantially straight state and a retaining passage for transferring the fiber product in a meandering state,
An annular processing tank for storing and arranging the endless textile product,
A bottom of the retention passage and an upstream end of the transfer passage are connected via a pump and a heat exchanger, and a treatment liquid circulation passage for circulating a treatment liquid with the treatment tank and an upstream end of the transfer passage. In a rope-shaped fiber product processing device comprising a processing liquid supply unit which is provided and supplies a processing liquid supplied by a processing liquid circulation path to the textile product for circulation processing, a cleaning liquid containing a cleaning liquid for cleaning the textile product. with the bath via a pump and flushing valve providing the treatment liquid circulation path and the cleaning solution supply path communicated, provided drainage valve for discharging the treating liquid stored in a bottom portion of the retention passages in the treatment liquid circulation path, wherein Of treatment liquid
When the cleaning liquid is drained , the cleaning liquid is located at the upstream end of the transfer passage.
It is supplied from the processing liquid supply unit and sprayed toward the textile product.
Isa was the textile while replacing the processing solution in the cleaning solution
It is characterized in that it is washed with a washing liquid .

[0008]

In the present invention, since the cleaning liquid tank containing the cleaning liquid for cleaning the textile product is provided with the cleaning liquid supply passage communicating with the processing liquid circulation passage through the pump and the cleaning valve,
When the processing liquid is drained , the cleaning liquid is located at the upstream end of the transfer passage.
Inject and supply from the processing liquid supply unit to the textile product
Since the textile product is washed with the cleaning liquid while the treatment liquid is sprayed toward the cleaning liquid while replacing the processing liquid with the cleaning liquid, it is possible to shift from the processing process to the cleaning process in a short time while the apparatus is operating.

By the jetting of the treatment liquid and the airflow from the treatment liquid jetting unit 4 and the airflow jetting unit 5, the treatment liquid is mixed in the airstream at the upstream end of the transfer passage 8 to become a gas-liquid mixed fluid and become a textile product a. Is sprayed toward the fiber product a, and the treatment liquid permeates the fiber product a. This textile product a is transferred in the transfer passage 8 by the injection of the processing liquid and the air flow from the processing liquid injection part 4 and the air flow injection part 5, and together with the sliding action due to its own weight, from the inlet side of the retention path 9 to the intermediate part. It reaches the section and is sufficiently retained in the middle section to be processed in a relaxed state. The textile product a is pushed out from the intermediate portion of the retention passage 9 toward the outlet side, pulled up to the header portion 7 by the drive reel 6, and the above-described operation is repeated again. On the other hand, surplus processing liquid is dropped from the porous nest plate 10 at the bottom of the stagnation passage 9, stored in the liquid storage section 13, collected in the processing liquid circulation path 2, and supplied to the processing liquid injection section 4 again. At this time, the drain valve 14 is in a closed state.

When the processing such as dyeing the textile product a is completed in this way, the washing of the textile product a is started. The cleaning of the textile product a is performed by the cleaning valve 2 in the cleaning liquid supply passage 27.

Be started by doing.
Then, the pump 11 of the treatment liquid circulation passage 2 is stopped, the opening / closing valve 15 in the treatment liquid circulation passage 2 is closed, and the drainage valve 14 is opened. By injecting and supplying the cleaning liquid, the processing liquid in the retention passage 9 is diluted and the processing liquid is replaced with the cleaning liquid, and the processing liquid being replaced with the cleaning liquid in the retention passage 9 is discharged from the liquid reservoir 13 ( See the dashed arrow in FIG. 2). In this manner, the cleaning liquid is injected and supplied, and the drain valve 14
By discharging the processing liquid from the cleaning liquid, the textile product a is finally washed with only the cleaning liquid while replacing the processing liquid in the retention passage 9 with the cleaning liquid.
