Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a nap raising nozzle component used in a liquid flow treatment apparatus and a method for manufacturing the same.

[0002]

2. Description of the Related Art Conventionally, it has been known that a knitted fabric such as cotton, wool, polyester, nylon, rayon and the like is raised at the same time as dyeing and other treatments in a liquid stream treating apparatus for fabrics. For example, as shown in Japanese Patent Publication No. 51-18556, an example in which a raised ring having irregularities on the inner surface is provided at a position close to the nozzle portion, and JP-A-59-
There is also an example in which a rough surface of a grindstone is provided on a running path of a fabric as in Japanese Patent No. 173364.

[0003]

However, the former raised ring shown in the above-mentioned known example has an example in which the contact portion with the cloth or the like is formed with irregularities, but when it is used for a long period of time. There is a drawback that the protrusion part is worn and the brushing effect is reduced.Although the latter example using a rough surface of a grindstone has a brushing action, it is extremely weak in impact resistance and there is a risk of damage due to falling when mounting or recombining. Since it has high performance and requires special equipment for manufacturing, it was not popularized as a practical machine or a production machine.

An object of the present invention is to solve the above-mentioned problems and to provide a nap raising nozzle part which is detachable and capable of exhibiting a nap raising action for a long period of time even when the surface is worn due to use. An object of the present invention is to provide a method for manufacturing a raised nozzle component.

In the second aspect of the invention, there is provided a method of manufacturing a raised nozzle component, in which a chlorine-based chemical liquid is applied to the inner surface of the stainless raised nozzle component, and the wet heat treatment is performed at a set temperature or higher. In the third invention, the method for producing a raised nozzle component according to claim 2, wherein sodium chlorite is used as the chlorine-based chemical liquid, and the wet heat treatment is performed at 90 ° C or higher. In the fourth aspect of the invention, a method for producing a raised nozzle component is provided, in which sodium hypochlorite is used as the chlorine-based chemical liquid, and wet heat treatment is performed at 45 ° C. or higher.

[0007]

In the first aspect of the present invention, since pitting corrosion is formed on the surface of the trumpet-shaped nozzle guide pipe extending from the retention tank to the treatment liquid jetting portion, there is always pitting due to pitting corrosion even on long-term use. A raising effect can be given to the cloth passing therethrough. The holes are not the ones that are formed by machining,
Since it is formed naturally and irregularly due to pitting corrosion, the raising effect does not decrease due to the abrasion due to the cloth contact, and the raising effect does not decrease forever.

According to the second aspect of the invention, a chlorine-based chemical liquid is applied to the surface of the stainless steel nozzle part which becomes the nozzle guide pipe,
Since the moist heat treatment is performed at a set temperature or higher, a large number of small holes can be formed in the surface of the nozzle part in a short time, and the nap raising action does not deteriorate even if abrasion occurs due to long-term use. Can now be manufactured.

In the third invention, sodium chlorite is used as the chlorine-based chemical solution, and in the fourth invention, sodium hypochlorite is used, and the moist heat action is carried out at 90 ° C. or 45 ° C., which are higher than the set temperatures, respectively. The holes formed are deep and have a small opening, and a nozzle part that can withstand long-term use can be manufactured.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the liquid flow treatment apparatus shown in the drawings will be described below. In FIG. 1, reference numeral 1 denotes a retention tank in which the treatment liquid is retained and the long fiber products such as a cloth-bonded fabric are temporarily retained while moving in a meandering shape. A transfer passage 2 is connected to the retention tank 1 at both ends to form an annular processing passage. Reference numeral 3 is a treatment liquid injection unit, which is connected to the outlet of the retention tank 1. 4 is the processing liquid,
5 shows a cloth. 6 is a roller. The cloth 5 is the retention tank 1
After passing through the roller 6, it is sent into the transfer passage 2 by the jet flow of the treatment liquid jetting unit 3 through the roller 6, and is again sent from the other end of the stagnant tank 1 into the stagnant tank 1 for circulation. During this period, the cloth and the like are subjected to dyeing, scouring and other treatments with the treatment liquid. 7
Is a processing liquid circulation path, and the processing liquid is at least 1 from the retention tank 1.
It is adapted to be sucked through the suction pipe from the individual adjusting port, pass through the pump 8 and the heat exchanger 9, and be jetted from the treatment liquid jetting section 3 to the transfer passage 2.

FIG. 2 is an enlarged cross-sectional view of the processing liquid ejecting section 3,
Is a trumpet-shaped nozzle guide pipe made of stainless steel. Reference numeral 11 denotes a nozzle portion, which is also made of stainless steel and is provided on the innermost periphery of the treatment liquid injection portion 3.
The nozzle guide pipe 10 and the nozzle portion 11 are nap raising nozzle parts. FIG. 4 is an enlarged cross-sectional view of the nap raising nozzle portion, in which a deeper corrosion portion is formed by the smaller holes 12 in the pitting corrosion.

In order to cause pitting corrosion, sodium chlorite or sodium hypochlorite was used as a chlorine-based chemical solution, and wet heat treatment was performed at a preset temperature of 90 ° C. or 45 ° C. or higher to form pitting corrosion. Therefore, in these nozzle parts, the protrusions are not worn due to contact even during long-term use, and the holes can always steadily perform the raising operation.

As the chlorine-based chemical liquid, hydrochloric acid, sodium chloride and the like can be applied, and is not limited to the above two types. The present invention can also be applied to the inner surfaces of the guide ring and the reel provided in the retention tank and the flow straightening cylinder provided in the transfer passage.

[0014]

According to the first aspect of the present invention, pitting corrosion is formed on the surface of the nozzle component cloth in contact with the cloth in the vicinity of the treatment liquid ejecting portion, so that the cloth can be surely given a raising action. ing. It can withstand long-term use, and even if it rubs a little, the small holes will appear one after another, so the brushing action is always kept good. Since these nozzle parts are detachable, they can be replaced and easily installed.

In the second aspect of the invention, since stainless steel is used to apply chlorinated chemicals to form pitting corrosion, even if it falls due to improper handling during installation / replacement,
There is no risk of damage, and since moist heat treatment is performed using a chlorine-based chemical at a set temperature or higher, pitting corrosion can be formed extremely easily and in a short time, and no special manufacturing equipment is required. effective.
