DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for processing a fiber product such as scouring, dyeing, and texture processing by circulating and rotating a rope-shaped cloth in an endless manner.

[0002]

2. Description of the Related Art Conventionally, a cloth processing apparatus has an air flow circulation path and a liquid flow circulation path. In the former, a gas is sucked from a processing tank by a circulation blower, is injected into the cloth circulation path, and passes through a cloth transfer pipe. To return to the treatment tank.

[0003] The latter is a path in which a liquid is sucked from a processing tank by a circulating pump and injected into a cloth circulation path or a gas circulation path and returned to the processing tank via a cloth transfer pipe.

[0004] A heat exchanger for heating and cooling the gas is provided outside the processing tank, and a heat exchanger for heating and cooling the liquid is provided outside the processing tank.

[0005]

On the circulation path is long distance as a whole since the heat exchanger is Te processor odor of textile products such as above SL which [0007] is added to the circulation path outside the treatment tank The heat exchanger occupies a large proportion of the processing liquid in the processing liquid circulation path outside the processing tank, and there is a limit to reducing the bath ratio.

[0006]

The present invention has been made in view of the above,
An annular cloth transfer passage is formed by a cloth transfer pipe for transferring a fiber product (hereinafter, simply referred to as cloth) in a straight state and a retaining section for transferring the fiber product in a meandering state, and an endless cloth is erected in the path. injection of liquid flow and / or air flow provided at the upstream side of the fabric transport tube, the liquid flow from the injection unit and / or
Alternatively, in the method of processing by circulating and rotating the cloth by the jetting force of the airflow, a cloth transfer pipe through which the fluid and the cloth pass.

[0007]

According to the present invention, the processing liquid impregnates the suction pipe connecting the processing tank with the circulation pump, the casing of the circulation pump, the pipe connecting the circulation pump and the injection section, a part of the injection section and the cloth transfer pipe, and the cloth. This is the sum of the liquid to be processed and the liquid separated and stored in the stagnant portion of the processing tank. The processing liquid circulating path can be formed at the shortest distance between the processing liquid storage portion 5 and the liquid jetting portion 8 via the pump P. Therefore, no wasteful processing liquid is required, and since the cloth, the processing liquid and the circulating gas are also heated in the cloth transfer pipe section, there is no need for an independent path required for heating, and the minimum required processing liquid is required. And the apparatus can be made compact without requiring a gas-specific heat exchanger in the gas circulation path.

[0008]

An embodiment will be described with reference to the drawings. In FIG. 1, reference numeral 1 denotes a long processing cloth bonded endlessly,
2 is a cloth processing tank, a cloth accumulation section 2a, a cloth lifting section 2b,
It has an annular structure composed of a stagnant portion inlet portion 2c, an injection portion 3 and a fabric transfer pipe 4, the upstream side of the transfer tube being connected to the jet portion 3 and the downstream side being connected to the inlet portion 2c of the stagnant portion.

The processing liquid circulating pump P is provided with a liquid reservoir 5 protruding from the bottom of the cloth retaining portion 2 a of the airflow treatment tank 2 and a suction pipe 6.
, And connected to the liquid jet unit 8 at the discharge pipe 7.

[0010] The gas circulation blower 9 is provided with a stagnant portion 2a of the cloth.
And a suction pipe 10 and a discharge pipe 11 connected to a gas injection unit 12. The cloth 1 is ejected from the liquid jet nozzle 8a from the lifting portion 2b of the stagnation portion 2a which moves in a meandering state, or the air jet nozzle 12
Each of them is lifted by a single action of the injection force injected from a or a combined action of the two, and is pressure-fed to the cloth transfer pipe 4 and is opened from the cloth transfer pipe 4 at the stagnant entrance 2c.

Reference numeral 13 denotes a heating device that covers the outer peripheral portion of the cloth transfer pipe 4. The heating device 13 simultaneously applies a heating effect to the gas, liquid, and the fabric as fluids to control the temperature to a predetermined temperature. It is measured by the temperature sensor 15.

The heating means is electricity, steam, combustion gas, etc. and is not limited. FIG. 1 shows a case where an electric heating coil is used, and FIG. 2 shows a case where steam or combustion gas is used as a heat medium. 3 shows the structure of a cylindrical wall.

[0013]

As described above, the apparatus for treating textile products having a low bath ratio according to the present invention is constructed as described above.
Since a heating device is provided on the outer periphery of the cloth transfer pipe, which is a passage for the liquid flow and the cloth, it is possible to simultaneously apply a heating effect to the air flow, the liquid flow and the cloth, and is disposed outside the processing tank as conventional. Air flow, a heat exchanger provided in a liquid flow path can be omitted, and a low bath ratio textile product processing method and apparatus capable of operating with a minimum processing liquid without filling an extra piping line with a processing liquid. Can be provided.
