Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides methods for scouring, bleaching, dyeing, and
The present invention relates to a treatment method for washing with water and other treatments, and a treatment device used therefor.

[Conventional technology]

As shown in FIG. 6, fiber materials such as gauze are usually received in the form of strips folded to a predetermined width and formed into a rectangular shape, and then supplied to various processing steps such as scouring and bleaching. Such processing of the fibrous material 3 has conventionally been carried out by filling a vertical cylindrical inner tank with the fibrous material 3 and loading this inner tank into a vertical cylindrical processing tank. That is, first, the rectangular fiber material 3 is folded into a ball, and then, as shown in FIG. Fill it up. The above-mentioned filling operation is usually performed manually by an operator. The inner tank 1 filled with the fiber material 3 in this way is then transformed into a processing tank 4 as shown in FIG.
The fibrous material 3 is processed by loading the fibrous material 3 and circulating the processing fluid in the direction of the arrow. 5 is a pump for circulating processing fluid, and 6 is a coil heat exchanger attached to the bottom of the processing tank 4.

[Problem that the invention seeks to solve]

However, in the above-mentioned processing method, the fiber material 3, which is originally folded into an angular shape, is folded into a round shape and filled into the inner tank 1, which has the disadvantage that many wrinkles occur in the fiber material 3. . In addition, since the fiber density in the gaps between the filled blocks of fiber material 3 is small and there is little resistance, the processing fluid flows through these gaps more than other parts, and the processing fluid does not flow sufficiently within the fiber material 3. This was causing uneven processing. Therefore, several proposals have been made to prevent the above-mentioned uneven processing by improving the flow of processing fluid (for example,
-23631 Publication), both use a cylindrical inner tank 1, so there remains the problem that wrinkles and uneven processing of the fiber material 3 occur due to the shape of the fiber material 3 and the inconvenience of the inner tank 1. Ta.

In contrast, the present applicant uses a rectangular inner tank in which the folded fiber material 3 (see Fig. 6) can be filled as it is without rolling it, and the processing fluid is pumped up and down with respect to this inner tank in a horizontal processing tank. We have developed a technology for processing by circulating it in both directions, and have already filed an application (Utility Application No. 1983-22099). When such a horizontal treatment tank and square inner tank are combined, there is a limit to increasing the amount of treatment at one time by stacking them in multiple stages, so for example, the above-mentioned Attempts have been made to load square inner tanks in parallel. However, in this case, the cross-sectional area of the part through which the processing fluid should pass is very large, so the processing fluid flow opening that communicates the processing tank and the inside of the inner tank is not provided, for example, just one at the bottom of the processing tank, as in the past. If the opening is simply provided, the flow rate of the processing fluid near the opening will be significantly different from the flow rate away from the opening, resulting in uneven processing. Therefore,
According to the position of the square inner tank loaded in parallel,
Although it is possible to provide two openings, a first flow opening that communicates with the rectangular inner tank on the back side and a second processing opening that communicates with the rectangular inner tank on the front side, it is possible to provide multiple openings in this way. Then, after loading the square inner tank, it is necessary to connect the two openings and the inside of each square inner tank to communicate with each other, which makes the work extremely complicated. In particular, work at the back of the treatment tank is not easy.

The present invention has been made in view of these circumstances, and it is possible to prevent wrinkles or voids from occurring when filling the fiber material.
The object of the present invention is to provide a method for processing fiber materials that does not cause uneven processing due to a uniform flow of processing fluid, and a processing apparatus used therein.

[Means for solving problems]

In order to achieve the above object, the present invention provides a treatment method for scouring, bleaching, dyeing, washing and other treatments on textile materials using a circulating treatment fluid,
A horizontal processing tank with an opening for flow of processing fluid at one place on the back side is prepared, a square inner tank filled with fiber material is loaded into the back side of the horizontal processing tank, and the inner tank is also filled with fiber material. The square inner tank is loaded into the front side of the horizontal processing tank, and a first processing fluid flow path through which half of the processing fluid flowing through the opening of the horizontal processing tank flows is inserted into the back side of the rectangular inner tank. A second processing fluid flow path through which the remaining half of the processing fluid flowing through the opening flows is communicated with the rectangular inner tank on the front side, and the horizontal processing tank is sealed into the processing tank. The first gist is a method for processing a fibrous material, in which the fibrous material is processed by distributing the supplied processing fluid in half to the front side and the back side of the processing tank in the vertical direction, Scouring, bleaching, dyeing, and
A processing device for performing water washing and other processing, comprising a horizontal processing tank having an opening/closing lid for loading and unloading the inner tank, and at least two square inner tanks each having a bottom surface with a flow hole and a non-porous side surface. a first trolley disposed at the back of the horizontal processing tank while supporting at least one of the rectangular inner tanks; a second trolley disposed on the front side of the tank, a processing fluid inlet/outlet opening provided at one location on the back side of the horizontal processing tank, and a processing fluid inlet/outlet opening provided on the back side of the first trolley. A first flow port is provided in the first truck to communicate with the processing fluid through only half of the processing fluid. A passage pipe through which the remaining half of the processing fluid passes is provided, and a second passage pipe communicating with the passage pipe of the first carriage is provided on the back side of the second carriage.
The second gist is a fiber material processing apparatus which is provided with a flow port.

[Effect]

That is, in the present invention, the inner tank, which has traditionally been vertical and cylindrical, is made into a rectangular shape so that the fiber material can be filled as is without having to be folded into a circle, so that the fiber material does not wrinkle. Further, since the entire fiber material is uniformly filled into the inner tank and treated with the treatment fluid flowing vertically in a laminar flow state, the flow velocity is not uneven and uniform treatment can be achieved. In particular, in the present invention, from the viewpoint of increasing the processing capacity, rectangular inner tanks are arranged in the horizontal processing tank on the back side and the front side, and an opening for processing fluid distribution is provided at one place on the back side of the horizontal processing tank. half of the processing fluid flowing through this opening is communicated and distributed in the rectangular inner tank on the back side, and the remaining half is communicated and distributed in the rectangular inner tank on the front side. The same amount of processing fluid flows through both the rectangular inner tank on the back side near the opening and the rectangular inner tank on the front side away from the opening, so that simultaneous processing in two rows is performed uniformly. What's more, all you have to do is load the square inner tank itself into the specified position from the back side.
Naturally, the opening on the processing tank side and the inside of each rectangular inner tank are designed to communicate with each other. There is no need to connect the inside of the inner tank and the opening on the processing tank side at the bottom of the tank. This is a major feature of the present invention.

Next, the present invention will be explained in detail based on examples.

The carts 12 and 13 are loaded into the 0.

As shown in FIG. 3, the trolley 12 has a gently curved bottom surface, and wheels 20 are attached at predetermined intervals on the outer side surface along the longitudinal direction. Further, a large diameter hole 21 is formed in the center of one side 12a on which the wheels 20 are not attached, and small diameter holes 22 and 23 are formed on the left and right sides of the large diameter hole 21.

On the other hand, as shown in FIG. 4, the trolley 13 has the same basic configuration as the trolley 12, but one side 12a of the sides on which the wheels 20 are not attached.
There is only a large diameter hole 26 made in the center, and there are no other openings. Furthermore, no pipe or the like is communicated with the large diameter hole 26. This trolley 13 also

Note that the carts 12 and 13 must be arranged as shown in FIG. 1 within the processing tank 10 in order to form a proper flow path. That is, the trolley 12 is placed on the back side of the processing tank 10 with the side surface 12a where the large diameter hole 21 and the small diameter holes 22, 23 are located on the back side, and the trolley 13 is placed on the back side of the processing tank 10 with the side surface 12a where the large diameter hole 21 and the small diameter holes 22, 23 are located on the back side. must be placed on the front side inside the processing tank 10 in a state where it is in contact with the side surface 12b of the trolley 12.

On the other hand, the back side 1 of the treatment tank 10 (return to Figure 1)
0b includes a large diameter hole 21 and small diameter holes 22, 2 on the back side 12a of the trolley 12 filled into the processing tank 10.
a first processing fluid inlet/outlet opening 30 communicating with 3;
A second processing fluid inlet/outlet opening 31 is provided which communicates with the gaps between the carts 12 and 13 and the inner wall of the processing tank 10 (in this case, the bottom of the processing tank 10), and is provided outside the processing tank 10 via piping. It is connected to a heat exchanger 32 and a processing fluid circulation pump 33.

Using the above processing apparatus, the fiber material 3 can be processed, for example, in the following manner. That is, first, the inner tank 11 is filled with the fiber material 3, which has been received in the form of a rectangular block shown in FIG. 6, as it is. When filling a plurality of lumps of fiber material 3, they are filled into the inner tank 11 in parallel. This inner tank 11 is first stacked in three stages on a trolley 12, and after fitting the upper lid 16, it is pressed and fixed, and the processing tank 10 (see Fig. 1)
Open the lid 10a and load the cart 12 into the processing tank 10 from the side. At this time, as already mentioned, the large diameter hole 21 and the small diameter hole 2 of the trolley 12 are
Arrange it so that the side with openings 2 and 23 is on the back side. Next, three different inner tanks 11 are stacked on the cart 13 and loaded into the front side of the processing tank 10 in the same manner as described above. At this time, as described above, the side surface on which the large diameter hole 24 is bored is placed on the back side. Then, the two carts 12 and 13 are arranged so that their adjacent sides are in close contact with each other without leaving any space between them.

In this state, the opening/closing lid 10a of the processing tank 10 is closed to seal the inside of the processing tank 10, and the processing fluid circulation pump 33 is operated, and the processing fluid heated by the heat exchanger 32 is transferred to the first processing as shown by arrow A. Processing fluid is supplied into the processing tank 10 by passing through the fluid opening 30 .

From the first processing fluid opening 30 to the processing tank 10
Half of the processing fluid supplied inside the carriage 12 passes through the small diameter holes 22 and 23 on the back side of the carriage 12 on the back side, and flows into the recess inside the carriage 12. Then, as shown by arrow B, it passes through the flow hole 11a at the bottom of the inner tank 11 and rises inside the fiber material 3. At this time, each fiber material 3
Since the space between the fibers is sufficiently filled and compressed without any voids, the rising treatment fluid flows in a laminar flow state and uniformly contacts each fiber forming the fiber material 3, thereby achieving uniform treatment.

Further, the remaining half of the processing fluid supplied into the processing tank 10 from the first processing fluid inlet/outlet opening 30 is transferred to the pipe 2 from the large diameter hole 21 on the back side of the rear truck 12.
5 and reaches the large diameter hole 24 on the opposite side, and further communicates with the large diameter hole 26 on the back side of the trolley 13.
It flows into the recessed part of the truck 13 through. Then, as shown by arrow C, it passes through the flow hole 11a at the bottom of the inner tank 11 and rises inside the fiber material 3, where it is processed in the same way as on the back side.

The processing fluid that has risen uniformly within the fiber material 3 in this manner passes through the upper lid 16 from the upper surface of the inner tank 11 and flows downward through the gap between the inner wall of the processing tank 10 and the side surface of the inner tank 11. After flowing down, the fluid passes through the gap between the carts 12 and 13 and the inner wall of the processing tank 10, passes through the heat exchanger 32 via a pipe from the second processing fluid inlet/output opening 31 communicating with the gap, and returns to the processing fluid circulation pump 33. The fiber material 3 is refluxed and repeatedly circulated within the treatment tank 10 to be used for the treatment of the fiber material 3.

However, the circulation of the processing fluid may be completely reversed. In this case, the processing fluid is supplied into the processing tank 10 from the second processing fluid inlet/outlet opening 31, rises through the gaps between the inner wall of the processing tank 10, the carts 12, 13, and the side surfaces of the inner tank 11, and rises to the upper surface of the upper lid 16. After reaching the inner tank 11, the first
The processing fluid flows back through the processing fluid inlet/outlet opening 30 to the processing fluid circulation pump 33 (opposite to the suction side in FIG. 1). Note that the processing fluid circulation pump 33 and the heat exchanger 3
2 may be arranged in any order.

〔Effect of the invention〕

As described above, when fiber materials are processed using the present invention, the fiber materials can be processed in the same form as they were received, and wrinkles and uneven processing, which have been problems in the past, do not occur. do not have. Moreover,
The square inner tanks are arranged in parallel on the front and back sides of the horizontal processing tank, and the processing fluid distribution opening provided at the back of the processing tank is communicated with each square inner tank to distribute the fluid evenly between each tank. Because the processing fluid is allowed to flow,
A large amount of fiber material can be processed simultaneously and uniformly.
