BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for treating textile products such as dyed fabrics and a method for producing textile products.

[0002]

2. Description of the Related Art Although liquid jet dyeing machines have a long history, rapid dyeing of equipment specifications has rapidly progressed due to short-time dyeing and low bath ratio. At the same time, in the dyeing technology, rapid improvement in the quality stability and productivity has been shown as compared with the past due to the high performance of equipment by rapidization and the development of dyes for rapid dyeing.

[0003] In a liquid flow processing apparatus for dyeing or other processing while circulating textiles such as cloth in a liquid flow in this manner, the processing liquid contains various dyes and other dyes depending on the type of the material to be dyed and the processing means. Chemicals, auxiliaries and the like are used. Many of these chemicals and auxiliaries generally have a high foaming property, and in particular, as the liquid flow treatment device has been rapidly developed, problems such as running troubles, color stains, and stains due to foaming have become apparent. Therefore, manufacturers of chemicals and auxiliaries have been developing low-foaming chemicals and auxiliaries, and at present, have produced some improvement effects.

[0004] Even in such a situation, it cannot be said that the problem caused by foaming during the liquid flow treatment has been solved. In most dyeing processing plants, chemical treatment, that is, stabilization of processing by using an "antifoaming agent" has been attempted. I'm measuring. This effect has a considerable foam-suppressing effect in the liquid flow treatment device, and can be said to be an indispensable method for solving troubles during processing.

[0005]

However, the side effect of an antifoaming material which lowers surface tension and suppresses foaming is extremely large, and oil spots due to oil contained in the antifoaming agent, or these oils and dyes, or Oligomers and sizing agents that are exuded from the inside of the fiber during dyeing accumulate and accumulate inside the retention tank of the fabric processing equipment, and this imitation adheres to the treated fabric and causes processing defects such as color stains and dye spots. It is often done.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned conventional problems. In the case where a textile product is dyed while traveling along an annular processing passage, or when other processing is performed, an auxiliary agent used for dyeing is used. An object of the present invention is to provide a liquid processing apparatus for a textile product and a method for producing a textile product, which suppresses foaming, obtains a stable state of transport of the textile product, prevents running trouble due to foaming, and does not cause processing defects. It is.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be further described below with reference to embodiments shown in the drawings.

FIG. 3 is a side view of a general liquid flow processing apparatus.

In FIG. 3, reference numeral 1 denotes a cloth retention tank,
The outlet of the storage tank 1 has a slope 1a that is inclined toward the traveling direction of the cloth 16 in order to pull up the cloth 16 from the processing liquid. And a transfer passage 2 connected from one end to the other end of the fabric.

On the other hand, the processing liquid is heated to a required temperature by a heat exchanger 7 from a processing liquid suction pipe 3, 4, 5 provided at the bottom of the storage tank 1 via a pump 6 and further,
Through the flow control valves respectively provided in the pipes branched from the outlet pipe of the heat exchanger 7, the processing liquid jetting sections 8A and 8B attached to one end are jetted toward the transfer passage 2 for the cloth. To form a processing liquid circulation path in which the liquid pressure is arbitrarily set. In addition, 19 is a liquid supply valve, 20
Is a flow control valve.

After the treatment cloth 16 is introduced into the cloth retention tank 1 by the treatment liquid jetting section 8A, it is mounted endlessly. During processing, the processing cloth 16 is retained in the stagnation tank 1 by the processing liquid spraying unit 8B.
The liquid is further pulled up and sent through the transfer pipe 2 together with the rapid liquid flow.

The present invention is directed to a liquid processing apparatus for processing a cloth while transferring the cloth together with a processing liquid in the circulation processing path. A jacket 9 is provided.

FIG. 1 is a side view showing an embodiment of the liquid processing apparatus according to the present invention.

This liquid processing apparatus, as shown in FIG.
A defoaming jacket 9 is provided on the rear side of the transfer passage 2. The defoaming jacket 9 is connected from the defoaming jacket 9 to a collection tank 11 via a foam transfer pipe 10, and foam generated in the transfer passage 2 is formed. Is collected. The recovery storage tank 11 is configured to circulate the processing liquid through the suction-side processing liquid circulation path 3 via the recovery liquid injection pump 12 in order to return the processing liquid to the main tank of the liquid flow processing equipment after sedimentation of the bubbles. ing.

[0023] In most of the liquid flow treatment facilities in the above circulation system,
The processing liquid passing through the transfer passage 2 is located at a lower portion of the passage, and the cloth is conveyed in a state of floating in the processing liquid. The processing liquid extruded by strong pressure in the injection nozzles 8A and 8B is mixed with air and inevitably foams, and the foam is pushed up by the upper layer of the transfer passage 2 and moves to the rear of the passage.
The foam pushed up at this time is collected from the defoaming jacket 9 through the foam conveying pipe 10 into the collecting storage tank 11.

FIG. 2 is a sectional view showing an example of a defoaming jacket according to the present invention.

The defoaming jacket 9 is preferably formed by forming a hole in the upper portion of a pipe (for example, a stainless steel pipe) forming the transfer passage 2 by punching to form a porous one. The size of the pores may be such that bubbles can pass therethrough, and usually about 2 to 4 mm is sufficient.

The defoaming jacket 9 is preferably installed at a portion where the pressure is high in the horizontal portion of the transfer passage 2, and more preferably at the rear outlet. The cloth and the processing liquid jetted under a high pressure from the liquid jetting nozzle portion 8A also utilize the fact that the flow velocity extremely decreases and the pressure inevitably increases in the rear part of the transfer passage 2. That is, the flow rate of the liquid and the cloth jetted from the jet nozzle 8A is reduced at the rear part of the transfer passage 2. When this phenomenon is confirmed by a differential pressure gauge, a pressure difference of about 50 to 200 mmAq occurs at a general nozzle pressure used, and this pressure difference is used. As shown in FIG. 2, the cross section of the defoaming jacket 9 is separated into a liquid phase and a gaseous phase portion, and the conveyed fabric 16 is generated together with the pressure in the transfer passage 2. It acts so that the foam can be pushed up to the foam transport tube 10 through the porous portion 15 of the porous transfer passage. Reference numeral 17 denotes a suction-side gate valve. When the gate valve 17 is closed, pushing up of the foam is prevented. However, when the gate valve 17 is opened, the foam is collected in the collecting tank 11 by a pressure difference. You.

The collected foam is defoamed in the storage tank 11 by settling or air pressure, or, preferably, water or treatment liquid containing a slight amount of defoaming material by a shower from a shower valve 14. Thereafter, the treatment liquid is returned to the suction-side treatment liquid circulation path via the injection pump 12 so as not to affect the dyeing on the fabric. Reference numeral 13 denotes an injection-side gate valve, and reference numeral 18 denotes a recovery storage tank discharge valve.

Normally, the bubble collection is started by judging the height of the cloth floating in front of the retaining tank 1 and operated. However, a liquid level sensor (not shown) provided in general liquid flow processing equipment is usually provided. ), It is also possible to automatically catch (control) the floating height of the cloth, open the suction-side gate valve 17 and collect the cloth in the collecting tank 11.

In the liquid flow treatment equipment, if the action of foams occurs frequently, the risk of processing increases, and a defective product is generated. However, appropriate foams improve running stability, and furthermore, rope wrinkles, clogging, etc. It has the effect of reducing wrinkles. With the apparatus of the present invention, it is possible to control appropriate foaming without completely defoaming, so that processing defects can be eliminated, and the prospect of stable processing without trouble can be obtained, leading to improvement in productivity. became.

[0030]

According to the present invention, with the above-mentioned structure, the floating phenomenon of the cloth and the running trouble (clothing clogging) due to the pushing of the front part inside the stay tank 1 due to the foaming are eliminated, and the defoaming is further reduced. Processing defects such as oil spots and dye stains due to the influence of the agent can be prevented beforehand.In equipment, not only the adhesion residue near the liquid surface but also the gap between the inner wall of the outer tank and the inner tank However, the problem of the adhesion residue on the side surface of the narrow portion can be solved, and the number of times of cleaning the can body can be reduced, thereby stabilizing the quality and improving the productivity.

Further, the present invention improves the stability of the fabric and eliminates processing defects without using a defoamer or other defoaming measures in a liquid flow treatment apparatus which has been conventionally implemented. Sex has come to be obtained.

In particular, in the jet dyeing of nylon fabric fibers, the leveling agent has a higher foaming property than the others, and the means for suppressing foaming must be dealt with by improving the dyeing aid and using an antifoaming agent. However, according to the present invention, since it is possible to collect the foam without inserting it into the holding tank at the same time as foaming, the fabric can be further speeded up, the dyeing time can be shortened, and the production can be stabilized. .
