BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid stream treatment method for fabrics and the like and a treatment apparatus therefor.

[0002]

2. Description of the Related Art Conventionally, dyeing, bleaching,
Liquid stream processing devices for scouring and other processes are widely known.
Moreover, a recent liquid flow processing apparatus is composed of a horizontally long processing tank, a header portion having one end connected to the processing tank and the other end having a roller or reel built therein, and a transfer passage connecting the processing liquid jetting portion. Many processing apparatuses that have an annular processing passage and that perform dyeing, bleaching, scouring, and the like while circulating and transporting a fabric by the jet of the jetting liquid from the treatment liquid jetting section are often employed.

For example, JP-A-62-243863,
This is as shown in JP-A-2-61159. What is shown in the drawing is an example of a conventional example, in which 1 is a treatment tank, in which a treatment liquid is accumulated and a long fiber product such as a fabric joined in a loop shape is transferred in a meandering shape. It is designed to store. Reference numeral 2 denotes a transfer passage, which is connected to the processing tank 1 at both ends to form an annular processing passage. Reference numeral 3 denotes a treatment liquid injection unit, which is connected to the outlet of the treatment tank 1. 4 indicates a treatment liquid, and 5 indicates a cloth. 11 is a reel. The cloth 5 is transferred from the processing tank 1 through the reel 11 into the transfer passage 2 by the jet flow of the processing liquid spraying unit 3, and is circulated so as to be sent into the processing tank 1 from the other end of the processing tank 1 again. During this time, the cloth or the like is subjected to dyeing or other processing with the processing liquid. Reference numeral 12 is a treatment liquid circulation passage, which is sucked from the treatment tank 1 through at least one adjusting port by a suction pipe, passes through a pump 13, a heat exchanger 14, and is ejected from the treatment liquid injection portion 3 to the transfer passage 2. It has become.

[0004]

However, in the above liquid stream processing method and apparatus, the cloth 5 and the like are spread from the end portion of the processing tank 1 by the roll or reel 11 portion built in the header portion. There was a drawback that rope creases were generated in the cloth 5 while the cloth 5 was transferred by the jet flow of the treatment liquid jet part 3.

Further, when a drive reel or a roll is used, there is a problem that threads or attrition is generated on the surface of the cloth. The rope wrinkle as used herein refers to a wrinkle that occurs in the lengthwise method of the cloth, and the thread refers to a case where a flowing gloss is generated on the surface of the cloth, or a slip is a case where a spot-like gloss occurs. An object of the method and apparatus of the present invention is to prevent the occurrence of rope wrinkles as described above, and also to provide a method and apparatus for treating a liquid such as a cloth without scratches or attrition.

[0006]

In order to achieve the above object, the method according to the first aspect of the present invention is a treatment tank for temporarily retaining fabrics joined in a loop, and a roll connected to the outlet of the treatment tank. An annular processing passage configured by a header portion having a built-in portion, a treatment liquid ejecting portion connected to the header portion, and a transfer passage having one end connected to the treatment tank and the other end connected to the treatment liquid ejecting portion. In the liquid flow processing method, which comprises dyeing and other processes while circulating and transporting the fabric by the jetting liquid flow from the processing liquid jetting part, the header part is pulled up slightly obliquely upward from the liquid surface of the processing tank. A liquid flow treatment method for a cloth or the like is formed so that a water film is formed between the roll and the cloth built in the header portion at a low position and branched from the pump discharge side pipe.

Further, as a device for realizing the above method, as a second invention, a processing tank for temporarily retaining the loop-bonded cloth, and a header which is connected to the outlet of the processing tank and has a roll built therein. Portion, a processing liquid injection part connected to this header part, an annular processing passage composed of a transfer passage having one end connected to the processing tank and the other end connected to the processing liquid injection part; In a flow treatment apparatus having a processing liquid circulation path that sucks the processing liquid from a tank and reaches the processing liquid jetting section via a pump and a heat exchanger, a low position in which the header portion is pulled up slightly obliquely upward from the processing tank. And one or more treatment liquid injection nozzles branched from the pump discharge side pipe toward the space between the roll and the fabric built in the header portion, and the treatment liquid injection nozzle ejects the treatment liquid in a fan shape. To do It was the fabric or the like of the liquid flow treatment apparatus.

[0008]

In the first aspect of the invention, the header portion connected to the processing tank is located at a lower position, which is pulled up slightly obliquely upward from the liquid surface of the processing tank. Therefore, the tension applied when the fabric moves to the roll in the header portion is relaxed. Since the water film is formed between the cloth and the roll, the cloth is prevented from coming into direct contact with the roll surface, and the jet flow provides a propulsive force that advances the cloth along the periphery of the roll. It was Furthermore, since the jet flow is fan-shaped, it has the effect of spreading the cloth over the width of the roll.

Further, in the second aspect of the invention, the pulling tension of the fabric can be relaxed and the roll surface can be smoothly moved by setting the position of the header relatively lower than the liquid level of the processing tank. Further, since the jetted liquid is jetted in a fan shape toward the space between the cloth and the roll, a water film is formed between the cloth and the roll, and a propulsive force is applied to the cloth by a strong jet flow to cause a spreading action. There is.

[0010]

Embodiments will be described below with reference to the drawings shown as embodiments. Reference numeral 1 is a processing tank, 2 is a transfer passage, and 3 is a processing liquid ejecting section. 4 indicates a treatment liquid, and 5 indicates a cloth. A header portion 7 having a roll 6 built therein is provided at the outlet of the treatment tank 1, and the treatment liquid ejecting portion 3 is connected thereto. One end of the transfer passage is connected to the processing tank 1, and the other end is connected to the processing liquid ejecting unit 3.
An annular processing passage is configured with the processing tank 1. The header portion 7 rises slightly above the liquid surface of the processing tank 1 and extends horizontally, so that the fabric 5 is not subjected to pulling tension.

Reference numeral 8 is an injection nozzle for injecting the treatment liquid toward between the cloth 5 and the roll 6. A pipe 9 is connected to the pump discharge side. A treatment liquid 10 is collected in the header portion 7 through the pipe 9, and is adapted to block the introduction of air when the cloth 5 is drawn in by the treatment liquid ejecting portion 3. Since the treatment liquid ejecting unit 3 and the transfer passage 2a are provided with a slight inclination and the transfer passage 2a is short, the running stability of the cloth is recognized.

In the apparatus of the present invention, the header portion 7 is provided at a position relatively lower than the liquid surface of the processing tank 1 so that the tension applied to the cloth 5 is relieved and the processing between the cloth 5 and the roll 6 by the spray nozzle 8 is performed. The liquid was jetted in a fan shape so that a water film was formed between the two. Therefore, the cloth 5 is given a propulsive force along the roll 6 by the pressure of the jet liquid, and a spreading action is given by the fan-shaped jet liquid.

FIG. 3 shows the position of the injection nozzle 8 and the pipe 9, and 6a shows the guide plates on both sides of the roll 6. In the present invention, since the cloth is processed while the cloth moves through the annular processing passage, and the jet liquid is supplied from the spray nozzle so that the cloth advances on the water film formed on the roll surface, the rope thread in this portion is applied. Wrinkles are prevented, and it is ideal for nylon fabrics that require a flat finish, especially for fabrics called taffeta, which not only has no rope creases, but also has a spreading action, and also causes threads and attrition. It is now possible to realize high-quality processing that is not possible.

[0014]

According to the first aspect of the present invention, the water film formed between the roll and the cloth and the fan-shaped jetting liquid from the jetting nozzle can perform dyeing and other treatments without rope wrinkles. Further, in the device of the second aspect of the present invention, by providing an injection nozzle between the cloth and the roll, a water film is formed between the cloth and the roll, a propulsive force is generated by the pressure of the injection liquid, and further a fan-shaped injection is performed. With the addition of spreading action, it has become possible to achieve high-grade processing without rope wrinkles.
