Description

[Detailed description of the invention] [Industrial field of application] This invention is a method for dyeing and dyeing in a liquid flow processing device for fabrics.
The present invention relates to a processing device for a rope-shaped fabric such as a liquid flow relaxer.

[Prior art]

In FIG. 5, which shows a partial schematic diagram of a conventional fabric liquid flow processing device, 1' is a retention section, 1b' is an upstream part of the reservoir section, 2' is a transfer pipe, 5a' and 5b' are casings, and 2.
4' is the liquid drain part 5d', 5 at the lower bottom of the casing.
Bypass piping from e' connected the processing liquid whose flow rate was adjusted by the valve 25' and the processing liquid from the downstream jacket to the suction pipe of the processing liquid circulation pump 21'.

[Problem that this invention attempts to solve]

Conventionally, the liquid drainage section at the bottom of the casing was controlled to separate the fabric from the processing liquid using only the bypass valve 25', and because no importance was placed on the pressure distribution to the fabric in the retention section, dyeing was carried out at a low bath ratio. , friction between the fabrics that perform liquid flow relaxation, friction between the fabric and the wall of the reservoir, uneven temperature distribution within the reservoir, etc., and prevents scratches and bumps that may occur, resulting in high-quality fabrics. It was difficult to stabilize operation.

[Means to solve the problem]

In order to solve the above-mentioned problem, the present invention installs an endless processing fabric (hereinafter simply referred to as fabric) in an annular passage of the fabric consisting of a transfer pipe and a retention section, and circulates and transfers it by a jet flow of processing liquid. A porous portion communicating with the processing liquid flow path on the bottom wall of the reservoir is formed in the lower bottom of the inclined casing provided at the inlet of the reservoir, and the porous portion communicates with the processing liquid flow path on the bottom wall of the reservoir. An on-off valve is provided for adjusting the amount of liquid flowing down the processing liquid flow path in the reservoir, and an upper bottom plate is provided that connects the downstream side of the processing liquid flow path to the lower bottom of the casing, and a lower plate is provided below the upper bottom plate. A double channel is formed in the lower part, and the downstream part of the lower channel is connected to the circulation path of the processing liquid. established,
Furthermore, the present invention is characterized in that a valve device is provided to adjust the amount of processing liquid flowing into the upper flow path.

[Effect]

In Fig. 1, the type of fabric that is likely to cause scratches or bumps is the one that enters the casing from the transfer pipe 2 because the transfer speed of the fabric is lower than that of the processing liquid, so the fabric that enters the casing from the transfer pipe 2 is processed. Pushed by the liquid velocity, the stagnation distribution pressure in the stagnation part is high in the upstream part and low in the downstream part, making it unbalanced. Therefore, depending on the type of fabric, the opening/closing valve 14 is set to be opened single-handedly or in conjunction with each other in the porous portions 5a and 5b, thereby performing a liquid separation action that reduces the speed of the processing liquid. The separated liquid in the casing is located at a higher position than the treated liquid level in the retention section, creating a pressure drop and trying to balance it with the liquid level downstream of the retention section.
Depending on the degree of opening, the processing liquid is distributed from the porous portion 7b of the upper flow path to the processing liquid flowing out and the processing liquid is transferred to the jacket, thereby creating an equal pressure distribution effect on the fabric within the retention portion.

In addition, in the treatment liquid circulation process, the treatment liquid heated in the heat exchanger 28 pulls the fabric through the treatment liquid injection part 3 and enters the casing via the transfer pipe 2, and the treatment liquid separated in the porous parts 5a and 5b is Because the mixed flow does not directly enter the circulation pump but acts within the stagnation section 1, the stagnation section 1
It becomes possible to make the temperature distribution state uniform inside.

〔Example〕

Next, embodiments of the present invention will be described based on the accompanying drawings.

FIG. 1 is a cross-sectional view showing the fabric processing state of the liquid flow processing device, in which 1 is the fabric retention section, 1a is the fabric lifting slope provided downstream of the accumulation section, and 32 is the processing liquid level. , 3 and 4 are processing liquid injection parts, which are provided at the outlet of the reservoir part 1 and the inlet of the transfer pipe 2. Reference numeral 5 denotes an inclined casing provided at the inlet of the storage section 1, and the lower bottom thereof has several porous holes 5a, 5.
b, 5c are provided, and the processing liquid flows through the flow path 5 on the bottom wall of the reservoir section.
It flows down to d. The porous portion is provided with a valve device that opens and closes the porous portion, so that all the porous portions can be opened or selected porous portions can be opened. This valve device is composed of a valve body 14 that acts on the porous portion and a drive mechanism 15 that moves the valve body forward and backward.

Reference numeral 7 denotes an upper bottom plate extending in connection with the lower bottom part of the casing, and includes a perforated part 7b, and its downstream end is fixed on the lower bottom plate 6 to form an upper bottom plate flow path (simply an upper flow path). 7a) is blocked.
Therefore, the treatment liquid flowing into the upper flow path 7a is ejected onto the fabric moving on the upper bottom plate 7. 6a
is a lower bottom plate flow path (simply referred to as lower flow path 6a). The upper bottom plate 7, the lower bottom plate 6, and the bottom wall of the reservoir part form an upper flow passage 7a and a lower flow passage 6a into upper and lower double layers. It forms a flow path. A flow control valve 8 is provided in the lower flow path 6a at the branching portion to adjust the amount of water distributed to the upper flow path and the lower flow path. The control valve 8 includes a butterfly valve 8' and a drive mechanism 1 for rotating the butterfly valve 8'.
It consists of 3. 9 indicates a rod, 10 indicates a packing, and 11 indicates a packing presser.

In this way, it is possible to adjust the draining of the fabric in the reservoir section and distribute and reuse the treatment liquid for fabrics that are likely to be scratched or hit, thereby making it possible to achieve uniform pressure distribution and uniform temperature distribution on the fabric.

[Effect of idea]

Since the present invention is as described above, unlike the conventional device described above, the liquid drain part, which is created only to separate the fabric and processing liquid and to avoid pump surging, is removed from the threads of the fabric.
For items that are likely to be hit, liquid drainage adjustment in the retention section, liquid separation opening/closing in consideration of uniform pressure distribution and uniform temperature distribution of the fabric by reusing treated liquid distribution,
Since liquid distribution is used, it is extremely effective in processing sensitive fabrics with high quality and stable operation.
