Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a liquid flow processing apparatus for rope-shaped fabrics.

[Prior art]

Conventionally, in a liquid flow processing apparatus for fabric, as shown in FIG. 4, the fabric 5' was transferred to the transfer pipe 2' by the same spraying force of a single processing liquid spraying section 3'.

[Problems to be solved by the present invention]

Therefore, when performing dyeing, liquid-flow relaxation, etc., if the injection pressure and injection flow rate are sensitive to fabrics that may cause eye wrinkles, it is recommended to spray the fabric with a constant flow rate during the dyeing, liquid-flow relaxation, etc. process. It was difficult to process with only a single injection part, as it required force adjustment.

[Means to solve the problem]

In view of the above, the present invention processes an endless treated fabric (hereinafter simply referred to as fabric) by circulating it in a treatment tank using a jet flow of a treatment liquid, and arranges the treatment liquid injection parts in multiple stages, In the case where each injection part is provided with a flow rate control valve, a first injection part 3a and a second injection part are provided in a communicating pipe of the same diameter that connects the inlet end of the transfer pipe 2 and the outlet end of the retention part 1. The jetting angles θ1 and θ2 of 3b are set so that θ1<θ2 to vary the impinging force of the jet stream against the fabric to control the magnitude of the kneading effect. Valve control means for controlling the flow rate regulating valves of each of the injection parts is provided, and the first injection part and the second injection part are operated selectively depending on the temperature of the processing liquid, or are operated simultaneously as necessary. That is.

[Operation] The operation when the fabric 5 is pulled by a combination of the treatment liquid injection section 3 with the first injection section 3a with the injection angle θ1 and the second injection section 3b with the injection angle θ2 will be described. For example, a light fabric weight of 75g/
For items around m ² that are likely to cause eye twists and hits, the injection gaps S1 and S2 of the first injection part and the second injection part are the same, the injection part diameters D1 and D2 are also the same, and the injection angle θ1 < θ2 If the temperature of the treatment liquid is low, the change in the physical properties of the fabric and treatment liquid is small, so the second injection part 3b with a large injection angle θ2 is operated to tow and transfer the fabric. In order to operate the first injection part 31 with a small injection angle θ1 when the temperature of the processing liquid enters a preset temperature range in which changes in the physical properties of the fabric and the processing liquid become large,
The flow control valve 26b is closed and the flow control valve 26a is opened.

In this way, when the injection flow rate of each injection part is the same, the smaller the injection angle is, the smaller the force hitting the fabric is, automatically minimizing the effect on the fabric, and the effect on the fabric and treatment liquid. We aim to improve the quality of fabrics by processing them according to changes in their physical properties.

Also, for fabrics with a heavy fabric weight of 150 g/ ^m2 or more, an absolute injection flow rate is required, so the first injection part and the second injection part
The injection gaps S1 and S2 of the injection part are the same and the injection diameter is D1.
and D2 are also the same, and in order to simultaneously inject those with the relationship of injection angle θ1 < θ2, the input data of the processing liquid temperature that is set in advance is eliminated, and the flow rate adjustment valve 2 during the same processing is
Use with 6a and 26b open.

In this way, when the injection flow rate of each injection part is the same amount, the force hitting the fabric can minimize the influence on the fabric by a small proportion of the injection angle compared to each injection angle θ1 = θ2, and obtain the absolute injection flow rate. This makes it possible to improve the quality of fabrics.

The direction guide section is provided between the multi-stage processing liquid injection section and the fourth processing liquid injection section. 15 and 16 are casings provided at the starting end of the retention tank; 18 and 20 are treatment liquid suction parts; 21, 26a, 26b, and 27 are flow control valves; and 19 is a suction pipe of the pump 17.

The processing liquid passes through a filter 23 via a discharge pipe 22, and is heated to a required temperature by a heat exchanger 24. 25 is a heat exchanger outlet pipe branched at its tip, and the injection flow rates of the first and second injection parts 3a and 3b and the injection part 4 are adjusted by flow rate regulating valves 26a, 26b and 27, respectively. 32 is a flow rate control valve 26
The temperature is controlled by a temperature sensor 32b by a valve control means that controls the opening and closing of the valves a and 26b.

The second injection part 3b has a diameter D2, an injection angle θ2, and an adjustable injection gap S2, and the first and second injection parts are switched or operated simultaneously by the respective flow rate control valves 26a and 26b. .

FIG. 3 shows a block diagram of the switching opening and closing of the flow control valves 26a and 26b, and each valve is automatically opened and closed according to instructions from the valve opening/closing control means 32. Note that 32a is a data input means for the valve opening/closing means 32, and 32b is a temperature sensor for inputting a signal obtained by reading a temporal change in processing temperature to the valve opening/closing means 32.

The valve opening/closing control means 32 is a data input means 32.

The valve opening/closing signal circuit 36 converts the command signal from the storage/arithmetic circuit 35 into a valve opening/closing instruction signal and outputs the valve opening/closing instruction signal.

Because of the above configuration, by providing a multi-stage injection section that combines different injection angles θ1 of the first injection section 3a and different injection angles θ2 of the second injection section 3b, it is possible to control the type of fabric and the physical properties of the treatment liquid. It becomes possible to use it according to changes.

〔Effect of the invention〕

Since the present invention is as described above, the magnitude of the kneading effect can be adjusted depending on the type of the object to be treated by selectively using multiple injection units having different collision forces of the injection liquid against the fabric or by using multiple units at the same time. It can be controlled and is extremely effective in practice.
