Since the fiber material can be stacked and filled in its original state, the fiber material does not move during processing and does not cause sink marks. Also, it will not lose its shape or wrinkle.

Therefore, the process to the finishing cellar 1 for adjusting the shape of the processed product becomes unnecessary, and it is possible to realize a significant improvement in production efficiency. Furthermore, in the present invention, prior to the treatment step,
The processing fluid is supplied from the bottom side of the processing tank, rises between the fiber materials, and then overflows, so when the processing fluid rises, the air held between the fiber materials is pushed out in both directions. to ensure sufficient deaeration. Therefore, it is possible to obtain a very good processed product with uniform distribution of the processing fluid.

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

〔Example〕

FIG. 1 shows an embodiment of the fiber material processing apparatus of the present invention. In the figure, reference numeral 10 denotes a horizontal cylindrical processing tank, and an opening/closing lid 10a provided at one end side allows the fiber material filling inner tank 11 to be taken in and out from the side. The inner tank 11, as shown in FIGS. 2(a) and (b),
It has a rectangular shape with an open top and one flow hole at the bottom.
1a is opened. Further, the side surface portion is non-porous, and rib plates 11b and 11c extending in the horizontal direction protrude from the upper and lower portions of the outer sides of the side surface along the longitudinal direction.

1. The inner tank 11 is loaded into the processing tank 10 together with the trolley 12 while being placed on the trolley 12 shown in FIG. This trolley 12 has a gently curved bottom surface, and wheels 20 are arranged at predetermined intervals on the outside of the side surface along the longitudinal direction.
is installed. Moreover, a communication hole 21 is opened in the center of one side 12a of the side surfaces to which the wheels 20 are not attached. This truck 12 can support the inner tank 11 as shown in FIG. 4 by placing a rib plate 11c projecting from the lower side of the inner tank 11 on its upper end. Then, after fitting the top cover 16 provided with the circulation hole 16a (see Fig. 1) through which the processing fluid flows in the vertical direction onto the top surface of the inner tank 1.1 at the top, the wheels 2
0 is placed on the rail] 5 (indicated by a chain line in FIG. 4) in the processing tank 10, and loaded into the processing tank 10 with the side with the circulation hole 21 facing toward the back. .

On the other hand, a second processing fluid inlet/outlet opening 30 is formed on the back side 10b of the processing tank 10 (return to FIG. Further, a first processing fluid inlet/outlet opening 31 is formed at the bottom of the processing tank 10 and communicates with a gap between the loaded cart 12 and the inner wall of the processing tank 10 . A heat exchanger 32 and a processing fluid circulation pump 33 are connected to a processing fluid circulation path connecting the second processing fluid inlet/outlet opening 30 and the first processing fluid inlet/outlet opening 31. Also,
34 is a gate valve provided in the middle of the processing fluid circulation path;
35 is a water supply valve.

Using the processing apparatus described above, fiber materials can be processed, for example, in the following manner. That is, first, the inner tank 11 is filled with fiber materials such as MAh vertical products in a horizontally spread state. For example, stockings are filled as shown in FIG. 5 when viewed from above. This inner tank 11,
First, the cart 12 is stacked in two tiers, the upper M16 is fitted and then fixed, the opening/closing lid 10a of the processing tank 10 (see Fig. 1) is opened, and the cart 12 is carried into the processing tank 10 from the side and placed in a predetermined position. Load it in position. At this time, the flow hole 21 of the trolley 12
Place it so that the open side faces toward the back.

In this state, the opening/closing 1i 10a of the processing tank 10 is closed to seal the inside of the processing tank 10, the gate valve 34 is closed, the water supply valve 35 is opened, the processing fluid circulation pump 33 is operated, and the heat exchanger The processing fluid heated by 32 is transferred to the processing tank 10.
The liquid is supplied into the interior and flows through the flow hole 21 of the truck 12. Then, as shown by the arrow, the inside of the inner tank 11 on the cart 12 is raised so that it overflows from the upper surface of the upper lid 16. At this time, the air held in the fiber material 3 in the inner tank 11 is pushed by the rising processing fluid and escapes from the two sides of the upper lid 16. Therefore, no air remains in the fiber material 3 and is completely replaced with the processing fluid. After a predetermined amount of processing fluid has been supplied in this way, the gate valve 34 is opened and the water supply valve 35 is closed, and the overflowing processing fluid is circulated as shown by arrow B, and the second processing fluid is supplied again. The passage opening 30 passes through the circulation hole 21 of the trolley 12 to the circulation hole 11. of the bottom of the inner tank 11. It is introduced into the inner tank 11 from point a and raised. At this time, the rising processing fluid flows in a laminar flow state and uniformly contacts each fiber forming the fiber material 3, so that uniform processing is performed.

The processing fluid that has uniformly risen inside the fiber material 3 passes through the J[16] from the top surface of the inner tank 11, flows downward through the gap between the inner wall of the processing tank 10 and the side surface of the inner tank 11, and then flows down into the first The processing fluid circulation pump 33 is supplied again from the processing fluid inlet/outlet opening 31.
It is refluxed and repeatedly circulated in the treatment tank 10 through the heat exchanger 32, and is used for the treatment of the fiber material 3.

Since the fiber material 3 processed in this manner is processed while being spread out in the horizontal direction, it does not move during processing and does not cause sink marks. Also, it won't lose its shape or get wrinkled. Moreover, at the initial supply stage of the processing fluid,
Since the deaeration is sufficient, a very uniform and good quality processed product can be obtained.

In the above embodiment, after water is supplied in the same manner as described above, there is no problem in reversing the suction/discharge functions of the processing fluid circulation pump 33 to reverse the circulation of the processing fluid. That is, the processing fluid is supplied into the processing tank 10 from the first processing fluid inlet/outlet opening 31, the gap between the inner wall of the processing tank 10 and the side surface of the inner tank 11 is raised, and the fluid flows down into the inner tank 11 from the upper surface of the upper lid 16. and the communication hole on the bottom of the inner tank 11], 1
The flow path may be followed in the reverse direction through the second processing fluid inlet/outlet opening 30 to the processing fluid circulation pump 33 (opposite to the suction side in FIG. 1).

In addition, near the bottom of the inner tank 11 and near the bottom of the upper M16, the processing fluid flows in a concentrated manner through the flow holes 11a on the bottom of the inner tank 11 and the flow holes 16a on the 1-lid 16, and the fibrous material hits these areas. Since the contact surface of No. 3 is processed excessively compared to other parts, in order to prevent this, as shown in Fig. 6,
First, on the bottom of each inner tank 11, a seal I-40 permeable to the processing fluid is attached.
After laying the fiber material 3, the same sheet 40 as above is laid on the upper surface of the fiber material 3, and then the inner tank 11 is filled.
It is preferable to stack them in layers and fit the top cover 16 thereto. The sea I-40 is formed of various fabric materials such as woven fabric and non-woven fabric.

[Effects of the Invention] As described above, when fiber materials are processed using the present invention, it is possible to process knitted = / stand-up products, etc. in a stationary state with them spread horizontally, which solves the conventional problems. There will be no sink marks or deformation that would otherwise occur. Therefore, there is no loss of processed products due to sink marks, and there is no need for finishing sets after processing, making it possible to significantly improve production efficiency. In addition, the processing fluid flows inside the fiber material.
Since the fiber material is supplied in an ascending manner, the air within the fiber material is sufficiently replaced with the treatment fluid, and the treatment fluid also has the effect of distributing the entire fiber + A mixture.
