Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and an apparatus for continuous heat treatment of a fabric in which the wet heat treatment is applied non-uniformly over the entire surface of a long fabric, that is, in an irregular manner.

For example, in the conventional method of continuously performing pre-treatments such as desizing, scouring, and whitening of fabric, it is known to use an i+-pull range developed by the present inventor or a high-pressure steamer. When the above-mentioned fabric is expected to undergo pre-treatment such as desizing, scouring, and bleaching at high speed, or when the fabric is expected to be continuously jagged or dyed, a high-pressure steamer can be used to achieve the desired high-speed processing. One promising option is treatment using a high-pressure steamer. f! )j
Processing methods have been proposed. However, the processing using a high-pressure steamer that has been proposed ( ) I'. In the case of high F [liquid tank installed outside the steamer or in the liquid seal tank formed inside the can of the high-pressure steamer], high F. Treatment liquid (caustic liquid during pre-treatment and weight reduction treatment, dyeing process 7)
At 41, the cloth to be treated is passed through a dyeing solution, etc.), and then this liquid-impregnated cloth is introduced into the surface pressure steamer can and heated to perform the desired treatment.

The moist heat generated by the conventional product steamer requires that the entire surface of the fabric be uniformly treated in a predetermined manner.
Jf, when impregnating this fabric with the specified treatment liquid, fill the fabric into the liquid tank.
It was like -mψ to be immersed in the liquid.

However, near l'l/i, there is a demand for treated fabrics in which the treated areas such as pre-treatment, weight reduction, dyeing, etc. are irregular (irregular), or the treated areas have a value of .

The present invention Q'1 was made in response to the demand for darning, and the 1st pressure broom A'! During the wet heat treatment, the fabric to be treated is continuously passed through a high-pressure steamer in which a The purpose of this paper is to provide a continuous moist heat treatment method for fabrics in which irregular reaction treatment parts are applied to the entire fabric, and its loading.

The present invention will be explained in detail below with reference to certain embodiments shown in the drawings.

Reference numeral 1 denotes a high-pressure steamer can for treating fabrics with a wet heat reaction.
In order to maintain moist heat of 00C or more and 160C, the fabric inlet 2 and fabric outlet 3 provided in the steamer can body 1 are provided with an inlet hole 1 sealing mechanism 4 and an outlet side sealing mechanism 5, respectively. There is.

This introduction (1'!+1 seal mechanism 4 is a substantially J-shaped passage 4
1, a pair of seal rubber rolls 42 for closing the upper opening of the passage 41, and a cold gas supply pipe 43 for supplying pressurized gas into the passage 41.

There is a slow cooling 4Y inside the outlet side sealing mechanism 5. 5, and furthermore, this slow cooling tank 51 has a cooling 7r'i

) has been slashed.

Inside the steamer can 4.1, there are a number of idle rolls 7 for transferring the fabric 6 to be treated in an up-and-down meandering manner.
is arranged compound 1. ing. Reference numeral 8 denotes a filtration device for the 4゛11 liquid discharged from the slow cooling tank 5□. , the heated 76 purified liquid is heated in the heat exchanger 10 piped into the steamer can body 1, and then this heated 76 purified liquid is heated in the heat exchanger 10 piped in the steamer can body 1.
1, the nozzle 12 is positioned at a suitable position within the steamer can body 1, and the fabric 6 is first directed toward the fabric 6 moving within the steamer can body 1.

The cleaning liquid flowing through the exchanger 10 is heated to a temperature of about 150° C. in the steamer can 1, for example. The filter device 8 can be used as long as it can continuously divert impurities such as dead weight and thread waste into the waste liquid discharged from the slow cooling tank 51. The inventor of the present invention is 1+, 'Q L', and the offshore device (4'!
No. 4-164573, Japanese Patent Application No. 54-164574, and Japanese Patent Application No. 111-1988-88471) can be used. 13 This is a liquid tank into which appropriate chemical solutions are added depending on the treatment.

The above is the configuration of this embodiment.Next, to describe its operation, pressurization and 2/- are blown into the steamer can body 1, and further into the passage 41 provided in the introduction side sealing mechanism 4, Gas is supplied from below through the gas supply pipe 43, and cooling water (It is supplied through the supply pipe 5□) into the slow cooling tank 51, and the inside of the steamer can body 1 is heated to high-temperature saturated steam at, for example, 160°C. There, the fabric 6 to be treated is fed into the steamer can 1 through the introduction-side knoll mechanism 4, and the fabric 6 fed into the steamer can has a target treatment 311.
! It is impregnated and coated with a chemical solution (for example, caustic solution, Somehon 2F, etc.) necessary for this purpose. This fabric 6 is supplied into the steamer can 1 and subjected to moist heat. When a part of the fabric 6 moving inside the steamer can 1 is intermittently sprayed with high-temperature liquid from the nozzle 12, the high-temperature liquid The reactivity of the mulberry agent in the area where it was sprayed is done quickly and well, and the agent in other areas, that is, the area that does not receive the liquid from the nozzle I2, remains unreacted or its reactivity is reduced. The desired non-uniformly treated fabric can be obtained with treatment unevenness of 14E.

As described above, in the present invention, when the fabric to be subjected to reaction treatment is transferred into the steamer can, a hot liquid to promote the reaction is sprayed onto a part of the fabric at an appropriate time. Because of this, uneven reaction occurs between the areas where the heated liquid is applied and the areas where it is not applied, and this causes irregularities! A treated fabric with unevenness, such as uneven dyeing or reduced density unevenness, can be obtained. Furthermore, in this embodiment, the waste liquid discharged from the slow cooling tank 51 is made into a cleaning liquid and then reused in the steamer can body l. )/p, and the liquid reused inside the steamer can is heated to a high temperature by a heat exchanger placed inside the steamer can and then applied to the fabric.
It has good reactivity to fabrics because it is
Moreover, it also has the effect of saving labor in thermal energy.
