Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a dyeing steamer, more specifically, a dyeing steamer, which is installed between a roof, which is a clay wall surface of a steamer box, and a guide roll positioned in the box, and which is used to heat the steam in the box. This invention relates to a dyeing steamer that has an intervening built-in interference member for preventing water droplets from falling so that the atmosphere is communicated.

In a dyeing process in which fabric is immersed in a dye solution and then the dye is fixed on the fabric, a steamer is often used as the fixing device. This type of dyeing steamer is designed to create a steam-heating atmosphere inside a box containing multiple guide rolls positioned in two levels (upper and lower), and is used to hold a long piece of fabric that has been dipped in a dye solution in advance. The dye is fixed on the fabric while being guided by guide rolls in a steam-heated atmosphere inside the box.

By the way, since each wall surface constituting the steamer box is in direct contact with the outside air, a portion of the steam condenses on these inner surfaces, causing water droplets to adhere. If this water droplet adheres to the bottom of the box, which is the lower wall surface of the box, the water droplets will simply be drained out of the box as is, and if it adheres to the side wall surface, it will travel along or along the side wall surface. The water falls and is similarly discharged outside the box as drain water.
In any case, these water droplets do not fall onto the fabric that is guided through the center of the guide rolls mounted on the left and right side walls of the box. However, if these water droplets adhere to the roof, which is the upper wall surface of the box, they will fall onto the fabric that is guided by guide rolls vertically below the roof.

On the other hand, some dyes have a strong affinity for water, while others have a weak affinity for water. When dyeing fabric using the former dye, if water droplets fall onto the fabric while the dye is being fixed with a steamer, the falling area will In particular, when water droplets fall onto the fabric on the fabric supply side of the steamer, when the dye is barely fixed on the fabric, the dye will be almost completely removed from the falling area. For example, when dyeing white fabric with red dye, the product will have white areas where water droplets fall. In such a case, the falling water droplets have a significant negative effect on the value of the dyed product, and even completely impair the product value.

Conventionally, in order to prevent water droplets from falling, which can have such a serious negative effect, we have used so-called heating tube steamers, which are equipped with heating means, such as steam heating means, to prevent the steam from condensing on the roof of the box. There is a so-called triangular roof type steamer in which the roof is sloped, generally with a triangular cross section, so that the attached water droplets travel along the roof and reach the side walls.

However, the former type of steamer has the advantage that the heating means can prevent steam from condensing on the roof and therefore prevent water droplets from falling.
This heating means requires extra thermal energy, and the equipment is expensive, making it uneconomical. On the other hand, while the steamer of the latter type does not have this drawback, it does have the drawback of not being able to completely prevent water droplets from falling. In other words, the inner surface of the roof is smooth;
There is no problem as long as the flow of water droplets traveling along the inner surface is not blocked, but if foreign matter adheres to the inner surface or the inner surface corrodes due to use, the flow of water droplets becomes blocked at that part and falls. . In such cases, it is unavoidable to periodically make the inner surface a smooth surface as described above, and there may be multiple guide rolls installed inside the steamer box. This operation is extremely troublesome, and it is also difficult to obtain a smooth surface as described above.

The present invention provides an improved dyeing steamer that eliminates such conventional drawbacks, and the object of the present invention is to provide an interference member for preventing water droplets from falling so that the steam heating atmosphere is communicated between the roof and the guide roll. The built-in interposition completely prevents water droplets from falling onto the fabric under economical conditions that save energy and labor.

Hereinafter, the configuration of the present invention will be explained in detail while comparing it with a conventional steamer based on the drawings.

FIG. 1 is a schematic side view illustrating a conventional so-called triangular roof type steamer, and FIG. 2 is a schematic cross-sectional view thereof. Inside the steamer box 1, a steam heating atmosphere is formed by live steam introduced from the bottom 11, which is the lower wall surface, natural exhaust from the exhaust port 31 of the roof 21, which is the earthen wall surface, and the fabric 2.
suction and exhaust from the exhaust port 51 of the side wall surface 41, which is the supply side, and drain water from the drain port 61 of the bottom portion 11;
This steam-heated atmosphere is kept as homogeneous as possible, and with some lift pressure, to maintain some kind of dry conditions. A long piece of fabric 2 pre-dipped in the dye solution 3 is fed into the box 1 according to the arrow A, and passed through the steam-heated atmosphere as described above to the left and right side walls 71, 81 of the box 1.
A plurality of guide rolls 14.
24.34, . . . , the dye is fixed on the fabric 2, and the thus fixed dyed product is transferred to the water sealing section 5.
, and is taken out of the box 1 in the direction of arrow B. During this time, as mentioned above, water droplets 1 attached to the roof 21
6.26.36 falls onto the fabric 2 as shown by arrow C, causing serious adverse effects.0 The present invention prevents water droplets from falling onto the fabric by using steam in a box between the roof and the guide roll. This is completely prevented by intervening interference members so that the heating atmosphere is communicated. 0 And FIGS. 3 to 5 show the case corresponding to the conventional steamer illustrated in FIGS. 1 and 2 above. FIG. 2 is a schematic diagram showing different embodiments of the present invention.

In the case of FIG. 3, as shown in the schematic cross-sectional view in FIG. 3(a) and the partial schematic perspective view in FIG. An interference member 17 whose central portion is curved in the direction of the roof 21 is interposed and built in between, and this interference member 17 is attached to the left and right side wall surfaces 71 and 81 with a gap 18 provided therebetween, and the gap 18 is formed between the guide roll 4a and the guide roll 4a. , 4b, the interference member 17 covers the fabric guided by the groups 4b in the vertical direction. Therefore, the roof 21
Water droplets falling from the cloth are caught by the interference member 17 and do not reach the cloth.

Generally, when operating this type of steamer, pressures of 2 to 4
Using steam of about kg/m, preheat for about 30 to 40 minutes while adjusting the exhaust and drain water as described above, and create a uniform steam heating atmosphere of about 100 to 105°C inside the box. In this state, the guide roll in the steam-heated atmosphere is in a kind of dry state. In the case of the present invention illustrated in FIG. 3, the box 1 is the interference member 1
7, but the steam heating atmosphere is divided into voids 1
8, the steam heating atmosphere inside the box 1 is uniform regardless of the interference member 17.

Therefore, in the operating state, the interference member 17
Similarly to guide rolls 4a and 4b, 100 to 105°C
The situation is somewhat dry. As a result, the interference member 17 is different from the roof 21 which is directly affected by the outside air.
The steam does not condense, and even if water droplets that have condensed on the roof 21 fall onto the crossing member 17, most of them will immediately vaporize again, completely preventing the water droplets from falling onto the fabric. It can be done.

In the case of FIG. 4, as shown in the schematic cross-sectional view of FIG. 4(a) and the partial schematic diagram of FIG. A plurality of interference members 27. whose central portions are inclined upward toward the roof 21.
37,... are interposed and built-in, and this interference member 27.37
, .PHI.. are attached to the left and right side wall surfaces 71 and 81 with a gap 28 provided between them in the vertical direction and partially overlapping (the shaded area in the figure).

Inside the box 1, the steam heating atmosphere communicates through a gap 28, and as in the case of FIG. 3, these interference members 27, 37
,... completely prevents water droplets from falling onto the fabric.

In the case of the embodiment illustrated in FIGS. 3 and 4, box 1
There is a clear gap 18 in which the steam heating atmosphere communicates.
．． 28, and an interference member 17, 27, 37 made of, for example, a thin plate made of stainless steel is interposed and built in, but communication of the steam heating atmosphere is not necessarily achieved through such a gap 18.2.
It is possible without providing 8.

In the case of FIG. 5, as shown in the schematic cross-sectional view, there is a gap between the upper guide rolls 4a and the roof 21 in the box 1 to the extent that water droplets falling from the roof 21 do not immediately pass through due to the surface tension. An interference member 47 made of a relatively dense wire mesh or a relatively coarse cloth with vapor permeability is interposed and built in, and this interference member 47 is attached to the left and right side wall surfaces 71, 81 almost horizontally under tension. . Even in this case, the inside of the box 1 is communicated with the steam heating atmosphere through the interference member 47, and as in the case of FIGS. 3 and 4, this interference member 47 prevents water droplets from falling onto the fabric. Completely preventable.

Interference member 17.27.3 of the steamer for staining according to the invention
7.47 may be installed over the entire area from the fabric supply side to the fabric take-out side in the box 1, but it may also be installed only on the fabric supply side where harmful dust from falling water droplets is strong; It is also preferable that the dye be attached before the dye is fixed to the fabric.

Finally, a specific example of the water droplet prevention effect of the dyeing steamer according to the present invention will be given. Under the following conditions, red Kayara Red F5G or Turkis Blue 〇L (trade name, manufactured by Nippon Kayaku Co., Ltd.), which has a strong affinity for water as a dye, can be used as a dye.
These are the results when a long bleached piece was dyed using 10g/ of the dye in an aqueous solution.

Conditions: Introduced steam pressure is 2 kg/d, preheating is 40 minutes,
The temperature inside the box is 100 to 105°C, the feeding speed for bleaching is 60 m/min, and the passing time for bleaching inside the box is 1 minute.Results: In case, bleaching after dyeing 100
There were 911 to 23 white dots per meter, but the fourth steamer had interference members interposed and built in over the entire area.
In the case of the present invention illustrated in the figure, no white spots were generated.

As explained above, the present invention includes a dyeing steamer that includes an intervening interference member for preventing water droplets from falling so that the steam heating atmosphere is communicated between the roof and the guide roll. It has the effect of completely preventing water droplets from falling onto the fabric and obtaining the desired high-quality dyed products under economical conditions that save energy and labor.
