Description

[Detailed Description of the Invention] The present invention provides the following steps when performing moist heat treatment on a fabric in a high-pressure steamer.
The present invention relates to a device that continuously processes the fabric by applying a temperature difference within a steamer.

For example, when scouring, bleaching, or dyeing a fabric, the fabric is fed into a high-pressure steamer in which high-pressure, moist heat is maintained at about 160°C, and the above-mentioned scouring, bleaching, or dyeing is performed under the high-pressure, moist heat.
Alternatively, the present inventor has proposed that dyeing be carried out at high speed and in a short period of time, and has filed numerous applications regarding this.

However, in the continuous wet heat treatment method for fabrics that has already been proposed, for example, when desizing, scouring, and bleaching fabrics are carried out continuously using a high-pressure steamer, the fabrics are first impregnated with a caustic solution and then The fabric is subjected to desizing and scouring using a high-pressure steamer that maintains moist heat at around 160°C, and then the treated fabric is impregnated with a hydrogen peroxide solution. It was bleached by moist heat treatment inside.

Therefore, in the conventional method, in order to continuously desizing, scouring, and bleaching fabric, it is necessary to use two high-pressure steamers with different moist heat temperatures, which results in high equipment costs and high pressure per steamer. Since the steamer is large, it has the disadvantage of requiring a large installation area.

In other words, hydrogen peroxide cannot withstand high temperatures of about 160°C, and caustic liquid has slow reactivity at temperatures of about 120°C (and is bad at temperatures higher than 120°C).
Because high temperatures were required, two high-pressure steamers were needed, one for desizing and scouring, and one for bleaching.

In addition, when dyeing different types of fibers simultaneously in one bath using, for example, disperse dyes and reactive dyes, each dye has a different heat resistance temperature. It was impossible to effectively dye any of them.

The present invention has been made in view of the above circumstances, and allows each process of desizing, scouring, bleaching, or multicolor dyeing to be performed effectively and continuously using one high-pressure steamer, thereby reducing the cost of steamer equipment. It is an object of the present invention to provide a high-pressure steamer that reduces the installation area and saves thermal energy, and that is easy to assemble, repair, and inspect the inside of the steamer can.

The present invention will be described in detail below based on embodiments shown in the drawings.

Figure 1 shows an example of continuous desizing, scouring, bleaching, or dyeing of fabric, in which 1A and 1B are the cans of two high-pressure steamers, one of which is placed in a high-temperature, moist heat chamber. Next, the other can body is placed in a low temperature, moist heat chamber.

The fabric inlet of the can body 1A and the outlet of the other can body 1B are provided with an inlet side sealing mechanism 2 and an outlet side sealing mechanism 3, which introduce and take out the fabric while maintaining moist heat inside the can body. , and the outlet of one can body 1A and the other can body 1B.
The two bodies are connected to the inlet through an intermediate sealing mechanism 4 so that they can be separated from each other.

These sealing mechanisms may be of any type as long as they allow the fabric to pass through but prevent the flow of moisture, and the sealing mechanisms developed by the present inventor and already filed may be selectively used.

Also, inside the can bodies 1A and 1B, there are guide rolls 6 for moving the fabric 5 in a vertical meandering pattern, dancer rolls 7 for adjusting the tension of the fabric transferred by the guide rolls 6, and drip-proof A plate 8 is provided.

Further, a liquid tank 9 for applying liquid to the fabric is arranged near the fabric insertion opening of the can body 1B.

10 is a water tank installed as necessary.

Next, the functions of an embodiment in which desizing, scouring, and bleaching are performed using the above-mentioned apparatus will be described.

First, the heat and humidity temperature of the can body 1A is adjusted to approximately 160°C, and the heat and humidity temperature of the can body 1B is adjusted to approximately 120°C.

Therefore, the fabric 5 before being supplied into the steamer can body 1A is impregnated with caustic liquid in an external liquid tank (not shown) or immediately after passing through the inlet side sealing mechanism 2 of the can body 1A. Desizing and scouring are performed by moist heat treatment at a temperature of 160° C. inside the can body 1A.

The fabric that has been desized and refined in the can body 1A is immediately impregnated with the hydrogen peroxide solution in the liquid tank 9 to the fabric 5 fed into the can body 1B.

Thus, the fabric 5 impregnated with the hydrogen peroxide solution is attached to the can body 1B.
By carrying out moist heat treatment at a low temperature of approximately 120°C within the range of 120°C, bleaching can be effectively carried out without damaging the hydrogen peroxide solution.

Next, a dyeing example using the above-mentioned apparatus will be described. This example is an example in which both different fibers of a fabric 5 made of 50% polyester fiber and 50% cotton fiber are continuously dyed.

In other words, polyester fibers are dyed using disperse dyes, and cotton fibers are dyed using reactive dyes. Since the reaction temperatures are different, effective dyeing cannot be achieved even if the process is carried out at a uniform temperature within one high-pressure steamer.

Therefore, in this embodiment, the can body 1A is approximately 1
A high humidity heat chamber where a temperature of 60°C is maintained, and a can body 1B.
The interior is a low-humidity heat chamber where a temperature of approximately 120°C is maintained.

The fabric 5 to which disperse dyes and reactive dyes have been mixed is supplied into a high humidity heat chamber using a liquid bath (not shown) in which the disperse dyes are mixed with polyester fibers. Only dyed.

Next, the fabric is fed into the can body 1B through the sealing mechanism 4, and is impregnated with the reducing agent placed in the liquid tank 9 under moist heat of about 120'C. The reactive dyes are dyed onto the cotton fibers.

In this way, the fabric dyed with both dyes is taken out from the high-pressure steamer main body, washed in the washing tank 11, and then transferred to the next process.

As described above, the present invention provides two methods for processing under high pressure and moist heat using chemicals with different processing temperatures or heat resistance temperatures.
A high-pressure steamer integrated by a can body on a stand is divided into a relatively high-humidity heat chamber and a low-humidity heat chamber, so that each treatment can be performed continuously at a moist heat temperature suitable for the processing chemicals. Therefore, it has the advantage of being able to perform effective treatment without damaging the chemicals.

Furthermore, since the two bodies are in contact only through the intermediate sealing mechanism, there is almost no risk that the high heat in the high-temperature, humid-heat chamber will be conducted to the low-temperature, humid-heat chamber, and the low-temperature, humid-heat chamber can be uniformly maintained at a predetermined comparative low temperature.

In addition, since the present invention has a structure in which the can body 1A and the can body 1B can be separated, it is possible to easily repair and inspect the inside of each can body by separating the can bodies. be.
