Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an airflow dyeing method and apparatus for rope-shaped fiber products.

[0002]

2. Description of the Related Art Conventionally, dyeing and other treatments of fabrics and other fiber products are carried out by continuous dyeing machine for dyeing in a spread state, dyeing is fixed by printing, or by using a jet dyeing machine. It is dyed by batch processing. In recent air-flow dyeing equipment, rope-shaped fiber products pulled up by a drive reel or roll provided in the header part
The gas is mixed with the gas-liquid mixed fluid, which is conveyed from the transfer pipe to the retention tank by the air flow ejected from the treatment fluid ejecting unit, is pulled up again from the retention tank by the drive reel or roll, and is circulated at the same time. The rope-shaped fiber product is circulated for dyeing or other treatment by being jetted and supplied from the treatment fluid jetting unit via a heat exchanger.

[0003]

However, among the above, in the processing by continuous dyeing and printing, since the cloth is conveyed in a spread state and is colored by a steamer, the cloth is processed while tension is applied, and the finished texture surface is obtained. It becomes flat, and the hardness remains so that consumers do not like it. Further, when treated with a jet dyeing device, the bath ratio is as large as 1:10 or more, so the heat energy cost required for heating / cooling is high, and even with the recent air dyeing device, the bath ratio is 1 : 3 or more, and there was a drawback that the thermal energy cost was high as in the case of the jet dyeing device.

The object of the present invention is to solve the above-mentioned problems, and after padding as a pretreatment step, as it is or after predrying, high temperature and high pressure treatment is carried out by an air flow type dyeing apparatus to develop color. An ultra-low bath ratio airflow dyeing device that can finish the texture of soft touch, minimize the consumption of water, dyes, and auxiliaries, and reduce the cost of heat energy required for heating / cooling the processing liquid. Is to provide.

[0005]

In order to achieve the above object, as a first invention, a rope-shaped fiber product pulled up by a drive reel or a roll provided in a header portion,
The processing fluid is ejected from the processing fluid ejecting unit to be transferred from the transfer pipe to the retention tank, and is pulled up from the retention tank by the drive reel or roll to be circulated, and the gas extracted from the retention tank is blown by a blower or heat. In an airflow dyeing method for a rope-shaped fiber product, which is circulated and processed by treating the fiber product by injecting it from a treatment fluid injecting device through a container, a dye is applied to the rope-shaped fiber product such as cloth. , After padding the chemicals, as it is, or after pre-drying, put it under high temperature and high pressure by the above airflow type dyeing device, and develop color by steam or high temperature airflow,
An airflow dyeing method for a rope-shaped fiber product, which was designed to give a rubbing effect, was used.

As a second invention, the rope-like fiber product is pulled up by a drive reel or roll provided in the header portion, conveyed by the air flow ejected from the processing fluid ejecting section from the transfer pipe to the retention tank, and again driven from the retention tank. Circulation processing passage that was pulled up by reel or roll,
A rope-shaped fiber such as a cloth in an air flow type dyeing apparatus, comprising: an air flow circulation path in which the gas withdrawn from the retention tank is jetted and supplied from the treatment fluid injection unit through a blower and a heat exchanger to circulate the gas. A padding device consisting of a dye solution tank and mangle for impregnating products with dyes and chemicals,
Alternatively, after passing through a preliminary dryer, it is put into the airflow type dyeing apparatus, a spray nozzle is attached to the airflow circulation path of the airflow type dyeing apparatus, and color is generated by steam or high temperature airflow under high temperature and high pressure to give a rubbing effect. The air-flow dyeing device for the rope-shaped fiber product was prepared.

[0007]

In the first aspect of the present invention, the rope-shaped fiber product is padded with the dye and chemicals before the high temperature and high pressure treatment process by the air flow type dyeing apparatus, so that the required amount of wetting and squeezing action can be obtained. In this state, or after passing through a preliminary dryer, it is sent to an airflow type dyeing apparatus, and circulation processing is performed by airflow under high temperature and high pressure, so that the padded dye is colored and fixed. The air stream is a dry material such as steam that has been superheated, and the rope-like fiber product is circulated by the air stream in a relaxed state and is subjected to a rubbing action.

In the second aspect of the invention, since the dyeing solution is impregnated and squeezed by the padding device, it is brought into an appropriate wet state, and this is left as it is or after passing through the pre-dryer, and then put into the air-flow type dyeing device and sealed. High-temperature and high-pressure treatment is carried out by the airflow in the circulation treatment passage thus formed, and during the circulation without tension, a very good relaxing effect and a kneading effect are obtained, and the coloring and fixing of the dye are carried out.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An air flow type dyeing device shown as an embodiment will be described below with reference to the drawings. Reference numeral 1 denotes a circulation processing passage, which is composed of a drive reel or roll 3 provided in the header portion 2, a transfer pipe 5 having a processing fluid ejecting portion 4, and a retention tank 6. 7 is a cloth or other rope-shaped fiber product, which is pulled up to the header portion 2 by the drive reel or roll 3;
It is transferred by a transfer pipe 5 having a processing fluid ejecting unit 4, passed through a retention tank 6, and again pulled up by a drive reel or roll 3 for circulation processing. Reference numeral 8 is a porous board provided at the bottom of the retention tank 6.

Reference numeral 9 denotes an air flow circulation path, and the gas withdrawn from the retention tank 6 is blown out by a blower 11 through a filter 10, heated by a heat exchanger 12, and sent from the treatment fluid injection section 4 to a transfer pipe 5. It is extracted again from the retention tank 6 and circulated. The air flow causes the rope-shaped fiber product 7 to circulate in the circulation processing passage 1. In FIG. 2, 13 is a steam introducing part, and 14 is a spray nozzle, which shows an example in which steam is directly introduced without passing through the heat exchanger 12.

In FIG. 3, 15 shows an example of a dyeing tank, and 16 shows an example of a mangle. The dye liquor is applied in the dye liquor tank 15 and uniformly squeezed by the mangle 16 to pad the dye and chemicals. In the present invention, after padding, the airflow type dyeing device circulates by the airflow, so that color is developed here, and the roughening effect is sufficiently exerted to give a soft touch texture. Whereas conventional continuous dyeing and printing are aimed at processing large lots,
The air flow dyeing device is intended for processing small lots, and since the color development and fixation after padding is done by the air flow, 1:
A low bath ratio of 2.5 or less was obtained, and a low bath ratio of 1: 1.5 for ordinary use and about 1: 0.8 for polyester fibers could be realized.

[0012]

As described above, according to the present invention, since airtight dyeing apparatus performs a closed high-temperature high-pressure treatment after padding, it is possible to obtain an extremely good fir tree effect at the same time as coloring, and to realize a soft touch texture. Became. In addition, the low bath ratio is 1: 2.5 or less, and the amount of dyes, auxiliaries, etc. can be reduced to the minimum necessary to reduce the heat energy cost required for heating / cooling, and texture processing can be performed at the same time as dyeing processing. Therefore, the process can be shortened.
