Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for treating a fabric with a high-temperature liquid, in which uniform moist heat treatment is continuously and effectively performed over the entire surface of a long fabric that is continuously transferred. be.

Conventional methods for continuously performing moist heat treatment (e.g., scouring, egg white, weight loss, dyeing, resin processing, etc.) on large quantities of long fabrics that are industrially processed and produced include, for example, the method developed by the present inventor. It has been proposed to perform continuous moist heat using a wet heat reaction chamber such as a pull range (part name) or a high-pressure steamer, but in such conventional continuous moist heat methods for long fabrics, first, a device installed outside the moist heat reaction chamber is used. The fabric to be treated is immersed and passed through the treatment liquid in the treatment liquid tank, and the excess liquid from the liquid-impregnated fabric is squeezed out with a squeezing roll. Intermediate drying is performed to prevent the fabric from adhering to rolls or guide rolls, etc., and then the fabric is fed into a steamer can (inside a moist heat reaction chamber) for steaming, and a chemical reaction is performed on the fabric. It was something.

However, in this conventional heat treatment method, the steamer needs to be kept in an atmosphere of high temperature and humidity before carrying out the moist heat treatment.
Since it takes a long time to maintain the temperature and humidity inside the steamer can, it takes a long time to prepare the fabric before it is put into operation. A large amount of thermal energy was expended to achieve this.

Unfortunately, the fabric inlet and outlet of the steamer can are
Continuous introduction and extraction of fabric is allowed, but if the steamer is equipped with a sealing mechanism to maintain high temperature and high humidity inside the steamer can, what is the overall structure of the steamer can? In addition, there were problems in that the size of the device was increased due to the demand for a pressure-resistant structure and a heat-resistant structure, and the cost of the device as a whole increased.

Furthermore, in the conventional continuous moist heat method, the fabric to be transferred is immersed and passed through the treatment liquid. There is a problem that causes uneven growth.

That is, since the width of the fabric is at least 90 Crn, in order to continuously squeeze the fabric, a squeezing roll with a length equal to or longer than the width of the fabric is required. With long squeezing rolls, the squeezing pressure is different between the center part of the fabric and the edges on both sides, so the liquid content is medium-diluted, medium-dense, or thick. There was a problem in that a phenomenon such as "wake-up" occurred, resulting in uneven processing.

The present invention has been made in view of the above, and the main purpose of the present invention is to provide a liquid seal in which a predetermined treatment liquid is uniformly absorbed and a liquid landscape is sequentially oozed out in a pre-adjusted amount to be absorbed into the fabric. The roll is brought into contact with the fabric to be treated, and the entire surface of the fabric is thoroughly and uniformly impregnated, and the treatment liquid transferred from the spreading roll to the fabric is transferred to an infrared burner. To provide a method for treating a fabric with a high-temperature liquid, which allows the fabric to be heated to a high temperature and penetrates into the inner core of the fabric, thereby speeding up the reaction by the treatment liquid, and achieving uniform moist heat treatment over the entire surface of the fabric. This is the purpose. In addition, we will accelerate the operation of moist heat treatment,
The aim is to provide a high-temperature liquid treatment method for fabrics that can simplify the structure of the steamer body, suppress waste of thermal energy, and perform highly economical liquid treatment. be.

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

Reference numeral 1 denotes a heat-and-moisture treatment chamber, and a heated liquid application section 2 is formed in the lower part of the heat-and-moisture treatment chamber 1.

The heated liquid applying unit 2 includes a cylindrical liquid sealing roll 5 for impregnating the fabric with a predetermined treatment liquid while guiding the fabric 4 to be treated introduced from the fabric cotton layer 3; The far infrared rays (
- 6 are arranged. Further, in the moist heat treatment chamber 1, a hot water application roll 5' having the same structure as the liquid seal application roll 5 is arranged so as to be able to guide and transport the fabric 4.

Next, the structure of the liquid sealing roll 5 or hot water applying roll 5' will be described. These rolls 5 or 5' are formed into a cylindrical shape of foamed metal having through holes 7 through which liquid passes, as shown in FIG. That is, in the enlarged cross section of this foamed metal, as shown in the same figure, countless thin liquid passage holes 7 (for example, 10 to 30/- holes) are formed that are irregularly bent or bent. Further, it is desirable to prepare in advance various diameters of the liquid passage holes 7 so that the optimum hole diameter can be selected depending on the viscosity of the liquid to be used or the desired liquid sealing to the fabric. Further, the liquid sealing roll 5 or the hot water applying roll 5' is connected to a highly hot water generating mechanism 10 as shown in FIG. This high-temperature liquid generation mechanism 10 includes a can body 11 that can be fully closed, a steam supply pipe 12 for supplying island-pressure steam into the can body 11, and a steam supply pipe 12 that keeps the steam pressure inside the can body 11 constant. There is an automatic internal pressure adjustment valve 13 to maintain the internal pressure, and a drain valve 14 used as necessary.
I'm being praised. Reference numeral 15 denotes a processing liquid heating pipe arranged in a meandering manner within the can body 11, and numeral 16 indicates a water heating pipe arranged spirally within the can body, which heats the processing liquid. The processing liquid and water supplied from the outside of the can body 11 are introduced into the pipe 15 and the water heating pipe 16 to the outside of the can body 11, and the processing liquid heating pipe 15 receives the above-mentioned liquid. The water heating pipe 16 is connected to the roll 5 and to the hot water application roll 5'.

However, the piping condition of these heating tubes 15 and 16 is not limited to this embodiment, but may be formed into an appropriate shape so as to easily receive the heat inside the can body 11, and furthermore, the heating tubes may be provided with a large number of blades. It may be attached to improve thermal conductivity.

Guide rolls 17 are arranged in the moist heat treatment chamber 1, and these guide rolls 17 allow the fabric 4 to be transported in a meandering manner without tension.

The above is the configuration of this embodiment.Next, its operation will be described. First, pressurized steam is supplied into the can body 11 through the steam supply pipe 12.
If the inside of this can body 11 is made into a high-pressure steam chamber of, for example, 5 Kq/cA by supplying steam, the temperature inside this can body 11 will be about 150
kept at ℃.

With this heating power of 150°C, the processing liquid heating tube 15 and water heating tube 16 arranged inside the can body 11 are heated to a value approximately 9150°C due to the heat conduction effect, so this processing liquid heating By passing the processing liquid and water under pressure into the tube 15 and the water heating tube 16, the processing liquid or water in these heating tubes is heated to approximately 150°C. The treatment liquid thus heated to a high temperature is fed under pressure to the liquid application roll 5 and is dispensed from the circumferential surface of this liquid application roll. Similarly, heated water oozes out from the hot water application roll 5' and is applied to and impregnated into the fabric as it moves through the heat treatment chamber 1. That is, from the liquid applying roll 5 and the hot water applying roll 5' of this embodiment, the heated liquid supplied to the inside of the roll passes through the liquid passage holes 7 that are irregularly bent and refracted, and reaches the outer periphery of the roll. Since a sufficient amount of the sardine liquid without excess is oozed out onto the fabric on the surface, the fabric guided in contact with the circumferential surface of these rolls is impregnated with all of the oozed liquid. It is something that can be done.

Then, by setting in advance so that all of the water seeped out on the peripheral surface of the liquid applying roll and the hot water J-3, O-roll can be absorbed into the fabric, and there is no excess, it can be applied to the fabric. It has the effect of ensuring that the temple juices are sufficient and not wasted. In addition, the thin liquid passage hole 7il''l provided in each application roll 5 or 5'
: Because the hole is irregularly bent or bent,
In order to cause the predetermined liquid to seep out from this liquid passage hole 7, it is necessary to pressurize the inside of the application roll 5.5' to an appropriate pressure. Since it is possible to maintain the temperature of the liquid in the roll 5.5' at a high temperature, the fabric can be directly impregnated with the high temperature liquid, which also has the effect of making it possible to apply the liquid with good penetration. Since the material supplied into the application roll 5.5' is pressurized, it is possible to uniformly ooze out pW over the entire length of the application roll 5.5'. It is possible to uniformly impregnate a fixed amount of liquid over the entire area.

Particularly in this embodiment, since the liquid uniformly applied to the fabric by the liquid application roll 5 is immediately heat-treated by the infrared heat burner 6, the solution rapidly penetrates into the inner core of the fabric, and the solution The reaction is also carried out well in the inner core of the fabric, for example, processing such as scouring, whitening, weight loss, dyeing, etc. is carried out well on the inner core of the fabric, resulting in a processed fabric of good quality. As described above, the present invention provides a method for injecting high-temperature liquid onto the circumferential surface of a roller that has countless liquid passage holes formed of irregular, DI curved, and bent fine communication holes on the entire circumferential surface. ooze out, transfer the oozing liquid to one side of the fabric, and at the same time apply far-infrared heat from the other side of the fabric to absorb the liquid into the inner core of the fabric! Since this is a high-temperature liquid treatment method for fabric having the following characteristics, the desired amount of heated liquid maintained at a high temperature, for example, 150°C, is applied 100% to the fabric to be treated using the liquid application roll. In addition, the liquid applied to the fabric can be completely absorbed into the inner core of the fabric by far infrared rays, so there is no wastage of liquid due to falling off of the melt, that is, unreacted liquid. Since the washing process after the liquid treatment can be simplified, it not only eliminates wasted liquid, but also saves water resources, simplifies the wet heat treatment equipment, and saves thermal energy, making it highly economical. It has the advantage of being able to mass-produce high-quality treated fabrics.
