BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid flow type textile product processing apparatus. More specifically, the present invention relates to a jet dyeing machine that performs processing by minimizing temperature hunting in accordance with processing solution jetting conditions.

[0002]

2. Description of the Related Art The temperature of a processing liquid is controlled by a single heat exchanger in the circulation of the processing liquid. Incidentally, there is one in which a plurality of heat exchangers are used in one processing machine (see Japanese Patent Laid-Open No. 49-
No. 81663) It is not provided in the processing liquid circulation path that connects the retention tank and the liquid injection unit.

[0003]

[Problems to be Solved by the Invention] Normally, a jet dyeing machine is used separately for dyeing treatment and can body washing treatment. However, in the case of can body washing, the treatment amount is 3 to 5 times the amount of treatment liquid used for dyeing. A large amount of heat exchanger is provided as much as possible in order to reduce the temperature rise time because it requires a liquid amount. Since the injection flow rate is extremely low, temperature hunting increases when using a heat exchanger in the case of the above washing, and uneven dyeing occurs due to the temperature difference, so it takes time to raise the temperature and minimize temperature hunting and dyeing time. It has been desired to shorten the period and improve the productivity.

The present invention solves the above-mentioned drawbacks and enables high-accuracy temperature control with minimum temperature hunting and rapid temperature rise for processes other than the temperature range necessary for dyeing, which is highly productive. The purpose is to provide a device.

[0005]

In order to solve the above-mentioned problems, the present invention connects a transfer pipe for transferring a fiber product (hereinafter referred to as treated cloth) in a straight state and a retention tank for transferring in a meandering state. To form an annular treatment cloth transfer passage, an endless treatment cloth is installed in the passage, and the treatment liquid is pressure-fed from the retention tank through a pump to a liquid injection section provided at the upstream end of the transfer pipe. In the case where the treatment liquid circulation passage is formed, the first treatment liquid circulation passage is used in the dyeing step.

Contrary forming the treated fabric according to the present invention endlessly, and connects the Todokotamari tank for transferring a serpentine state transfer pipe for transferring an annular treated fabric transport path in straight state, the transfer pipe upstream A process to reach the liquid injection unit through a liquid injection unit arranged at the end, while one or more suction pipes and pumps provided in the retention tank and two heat exchangers arranged in series or in parallel are provided. Forming a liquid circulation path, one of the two heat exchangers is provided with a temperature raising ability having a temperature characteristic required for dyeing, and the other heat exchanger for dyeing for the purpose of a can body washing step. 3-5
One or both heat exchangers can be arbitrarily selected by giving the double heating ability.

That is, when dyeing a delicate low-basis weight fabric endlessly bonded, the jet flow rate from the liquid jetting part is extremely small in order to obtain stable running of the fabric. By using only the heat exchanger for the purpose of minimizing the temperature difference due to temperature hunting and preventing uneven dyeing, by using two heat exchangers, 3 to 5 at the time of dyeing can be obtained. In the can body cleaning process that requires double the amount of processing liquid and the process where temperature hunting is not a problem, rapid heating and cooling can be performed to shorten the processing time and significantly improve productivity. It was done.

Embodiments of the present invention will be described below with reference to the accompanying drawings. In FIG. 1, reference numeral 1 designates a retention tank having an inlet portion 2 and an outlet portion 3 at both ends. Reference numeral 4 denotes a transfer pipe for transferring the treated cloth 9 in a straight line, and a liquid injection part 5 is provided at the upstream end. 6 is a surface of the treatment liquid, and 7 is a casing provided at the inlet 2 of the stagnant tank 1, which is formed of a perforated plate and has a structure in which a part of the treatment liquid falls. A drive reel 8 sends the treated cloth 9 to the transfer pipe 4 and circulates the treated cloth 9, and the treated cloth 9 is pulled up from the treated liquid surface 6 and fed to the liquid ejecting unit 5.

Reference numerals 10 and 11 denote treatment liquid suction portions, and 12 denotes suction portion collecting pipes, which constitute a first heat exchanger 13 by incorporating a steam pipe 13 'therein. 14 is a main pump. The treatment liquid passes through the discharge pipe 15, the filter 16 and the second heat exchanger 17, and is branched by the heat exchanger outlet pipe 18. One reaches the liquid injection unit 5 through the flow rate control valve 19 and the other one. It is connected to the reverse injection unit 22 via the flow rate control valve 21.
Reference numeral 20 is a flow rate control valve of the shower directed to the cloth inlet of the liquid ejecting unit 5.

The heating capacity of the second heat exchanger 17 is 3 to 5 times that of the first heat exchanger 13. 23 and 24 are steam inlet control valves, 25 and
26 is a steam trap. First heat exchanger and second
Each heat exchanger is equipped with a cooling water control valve (not shown). Reference numeral 27 is a water intake valve, and 28 is a drainage valve.

The treated cloth 9 is transferred to the transfer pipe 4 by the liquid jetting unit 5.
After being introduced into the retention tank 1 through the above, it is mounted endlessly.
During the treatment, the treated cloth 9 is pulled up from the outlet of the retention tank 1 by the liquid jetting section 5 and sent through the transfer pipe 4 together with the rapid liquid flow, and again sent from the casing 7 to the retention tank 1 to repeat the circulation transfer. When dyeing reaches an important temperature range during dyeing, the first
Only the steam inlet control valve 24 is controlled so that only the heat exchanger 13 operates, and the process proceeds according to a temperature program prepared in advance.

Next, the two steam inlet control valves 23 and 24 can be controlled at the same time in the dyeing temperature range where temperature hunting does not pose a problem, the washing of the can body, and the like. According to the first aspect of the present invention, the temperature raising capacity is minimized when the jet flow rate from the liquid jetting section 5 is extremely small and a large temperature hunting is likely to occur, such as a dyeing treatment of a low-basis weight fabric. The first heat exchanger 13 and the second heat exchanger 17 are used when the temperature difference is minimized by the heat exchanger 13 and a large processing flow rate such as a can body washing process is required and a shortening of the temperature raising time is desired. Both are used so that the processing time can be significantly shortened.

As described above, the present invention can prevent the uneven dyeing by minimizing the temperature hunting by using only the first heat exchanger (13) in the dyeing process, and at the same time, the problem of the temperature hunting is solved. Only the second heat exchanger (17) or this and the first heat exchanger (13) in the can body washing process which does not become
By using these together to rapidly raise the temperature and cool, the processing time can be shortened and the productivity can be greatly improved.
