Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to the structure of a nozzle for continuous processing of fabric, which is advantageous for continuous wet heat treatment or cold air treatment of fabric.

[Background of the idea]

For example, conventional methods of continuously scouring, bleaching, dyeing, resin processing, weight loss processing, etc. on industrially produced long fabrics allow continuous insertion of the fabric, but it is necessary to maintain high temperature and high humidity. The fabric is subjected to continuous moist heat treatment at high temperature and high humidity using a steamer can, i.e., a reactor, which can be used to perform continuous wet heat treatment at high temperature and high humidity.
It has been proposed to continuously carry out targeted treatments such as bleaching, dyeing, resin processing, and weight reduction processing.

However, in such a method for continuous moist heat treatment of fabrics, it is necessary to maintain a high temperature and high humidity atmosphere inside the steamer can prior to the wet heat treatment. Since it takes a long time to reach high humidity, it takes a long time to prepare the fabric for operation, and furthermore, a large amount of thermal energy is expended until the inside of the steamer can reaches the specified temperature and humidity. It was something that would be done.

In addition, the fabric can be continuously introduced and taken out through the fabric inlet and outlet of the steamer can, but if the fabric is equipped with a sealing mechanism to maintain high temperature and high humidity inside the steamer can, , the overall structure of the steamer can becomes complicated,
Furthermore, with the demand for pressure-resistant and heat-resistant structures, the size of the device may increase, and the cost of the entire device may also increase. In view of this, the inventor of the present invention aimed to speed up the moist heat treatment operation by directly blowing high-temperature, high-humidity gas onto the fabric to be treated using a jetting force from a nozzle, and at the same time, using a steamer can. We are proposing a high-temperature liquid injection nozzle that can simplify the body structure, but with this nozzle structure,
For example, even if the temperature of the high-temperature liquid to be injected from the nozzle opening is increased by pressurizing it to, say, 150°C, it will vaporize immediately after being ejected from the nozzle opening, resulting in a rapid temperature drop, and furthermore, it will be scattered and lose heat energy. When the loss increases, the following problems can be considered.

[Purpose of invention]

The present invention has been made in view of this problem, and it is an object of the present invention to provide a nozzle for continuous processing of fabric, which is configured to increase the efficiency of applying high-temperature liquid or cold air to the fabric, which is sprayed from the nozzle opening. This is the purpose.

[Example of idea]

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

Reference numeral 1 denotes a pressure- and heat-resistant high-temperature liquid injection tube having a large number of pores or slit-shaped nozzle openings 2 in the generatrix direction. A mouth 3 is provided. Reference numeral 4 denotes frames having a substantially V-shaped cross section that are formed close to both sides of the nozzle opening 2, and these frames 4 are formed integrally with the high-temperature liquid injection pipe 1, and the tips of these frames are The fabric 5 that is transferred close to the high-temperature liquid injection pipe 1 comes into sliding contact with the fabric 5 to prevent the fluid injected from the nozzle opening 2 from scattering.
In the embodiment shown in FIG. 1, the frame 4 is missing at both ends of the high-temperature liquid injection tube 1, but if the frame is applied to these missing parts, the prevention of fluid scattering will be more effective.

In this way, in this embodiment, the nozzle opening 2 is inserted along the edge of the nozzle opening 2 provided in the high-temperature liquid injection pipe 1.
A frame 4 is provided to suppress the scattering of, for example, 150°C high-temperature liquid spouted from the
Since the fabric 5 is transferred in contact with the fabric 5, the amount of the heat of vaporization ejected from the nozzle opening 2 scatters is small, and the efficiency of imparting the amount of heat to the fabric 5 is improved. Furthermore, since a chamber 6 surrounded by the frame 4 is formed between the nozzle opening 2 and the fabric 5, the pressure inside this chamber 6 is slightly higher than the outside pressure due to the action of the high-temperature injection pressure. It is possible to suppress the sudden drop in the high-temperature liquid spouted from the high-temperature liquid injection tube 1, and to directly apply the high-temperature liquid with a temperature close to the internal temperature of the high-temperature liquid injection pipe 1 to the fabric 5.
Uniform high-temperature liquid treatment can be performed over the entire surface of the fabric. Although the pipe 1 is described as a high-temperature injection pipe in this embodiment, it is not limited to this.
For example, it can also be used for cooling or drying fabrics by passing cold liquid, cold air, hot air, etc.

[Summary of the idea]

As described above, the present invention provides a frame 4 along the edge of the nozzle port 2 provided in the fluid injection pipe 1 to suppress fluctuations in the temperature of the fluid ejected from the nozzle port 2 and to suppress scattering of the fluid. This is a nozzle for continuous processing of fabric, which is characterized by being conveyed in contact with a frame 4.

[Effect of idea]

Therefore, this frame 4 suppresses temperature changes that occur when the fluid injected from the nozzle port 2 comes into contact with external pressure, and also prevents the fluid from scattering, thereby reducing thermal energy loss. It has the advantage that heat treatment of fabric can be effectively achieved.
