Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for stabilizing the form of a fiber product and an apparatus used therefor.

[0002]

2. Description of the Related Art Conventionally, in order to improve the dimensional stability of textile products, a heat setting treatment using steam has been performed in the finishing process. Among them, cellulose fibers (cotton, rayon, hemp, etc.) have been used. Textiles mainly composed of animal and animal fibers (wool, silk, etc.) are particularly susceptible to wrinkling and shape loss. A special form stabilization process is actively performed to fix (store) the shape of the fiber in advance so that wrinkles are hardly formed and the shape does not collapse.

[0003] As the above-mentioned form stabilization processing, conventionally,
It is well known that a chemical such as formalin-based resin or ammonia is applied to the fiber to form cross-links in the molecular arrangement of the fiber to maintain the fiber shape. Due to the above-mentioned problems, a high-temperature steam (for example, 1
(80 ° C.) has been proposed and partially implemented.

[0004]

However, when the above-mentioned steam treatment is adopted, particularly when the textile to be treated is in the form of a package (eg, cheese, beam, etc.), it is difficult to sufficiently diffuse the steam to the inside of the package. so,
There is a problem that the treatment is often performed only on the surface.

Therefore, as a method of improvement, a method has been attempted in which the inside of the treatment tank is evacuated before introducing the steam so that the steam easily diffuses and permeates. However, this method is also necessary for stabilizing the form. It is difficult to keep the inside of the package sufficiently replenished with water vapor, and as a result, it is not possible to obtain a processed product that is as uniform as desired.

[0006] As another improvement method, steam is treated as gas, and the steam is blown using a blower (such as a blower).
A method of forcibly circulating the air inside and outside the package has also been attempted, but since steam is a condensable gas, unlike an uncondensable gas such as air, a large amount of condensation occurs in the steam circulation path, There is a problem that the dew water is brought into the packaged fiber product and significantly impairs the uniformity of the heat treatment. Moreover, the blower for high temperature steam is
Since it is extremely expensive, there is an obstacle that the equipment cost is high.

The present invention has been made in view of such circumstances, and it is very simple and inexpensive to sufficiently diffuse and infiltrate high-temperature steam into the interior of textiles, especially packaged textiles, to perform uniform treatment. It is an object of the present invention to provide an excellent morphological stabilization method which can be performed and an apparatus used therefor.

[0008]

Means for Solving the Problems In order to achieve the above object, the present invention provides a method for performing a form stabilization treatment on a fiber product mainly composed of at least one of a cellulosic fiber and an animal fiber, The above fiber product is loaded into a processing tank provided with a steam inlet and a steam outlet, and in that state, high-temperature steam is continuously or intermittently introduced from the steam inlet and the inside of the processing tank is provided from the steam outlet. A fiber product that generates a moving flow of high-temperature steam and passes through the inside and outside of the fiber product by continuously or intermittently releasing high-temperature steam to maintain the inside of the processing tank at a predetermined morphological stabilization temperature. The first aspect of the present invention is a form stabilization processing method.

Further, the present invention is an apparatus used for performing a form stabilization treatment on a fiber product mainly composed of at least one of a cellulosic fiber and an animal fiber, wherein high-temperature steam is continuously or intermittently applied. A treatment tank provided with a steam inlet capable of introducing a gas, a steam discharge port capable of continuously or intermittently releasing high-temperature steam to the outside, and a textile product held on a high-temperature steam transfer passage in the processing tank. Fiber product holding means, measuring means for measuring the temperature or steam pressure in the treatment tank over time, and the amount of high-temperature steam introduced from the steam inlet and the high temperature from the steam outlet based on the measurement results by the measuring means. Temperature control means for maintaining the temperature in the processing tank at a predetermined shape stabilization temperature by controlling at least one of the amount of water vapor release. The device as a second aspect.

That is, according to the present invention, a part of a processing tank filled with high-temperature steam is released to the atmosphere continuously or intermittently, thereby releasing high-temperature steam from an opening (steam discharging port). The moving flow of water vapor generated at this time is passed through the inside and outside of the textile, so that the interior of the textile is sufficiently contacted with the water vapor. According to this method, utilizing the pressure difference between the high pressure of high temperature steam and the atmospheric pressure, in a very short time and with a small amount of steam,
Uniform shape stabilization processing can be performed. And the processing cost is also low.

[0011]

Next, one embodiment of the present invention will be described in detail.

First, the fibers to which the present invention is directed are fibers mainly composed of cellulosic fibers such as cotton, rayon and hemp, and animal fibers such as wool and silk, which have been required to have a stable form. It is. In the present invention, the term "mainly" means not only a fiber product consisting of only these fibers, but also a synthetic fiber blended fiber product in which these fibers are used in combination with other fibers.

[0013] The form of the textile product to which the present invention is applied may be any form, for example, any of rose hair, filament, tow, sliver, thread, woven or knitted fabric, and non-woven fabric. You may. Alternatively, it may be tailored to the shape of the final product, such as a shirt or garment.

[0014] In the process of the present invention,
It is set appropriately according to the form of the fiber product. In other words, the loose hairs are packed in a tank in a basket, the yarns are wrapped in a skein, cheese, cone, etc. and packaged, and the woven, knitted, non-woven fabrics are wound and packaged in a beam or the like. Can be processed. In addition, yarns, woven or knitted fabrics, etc. can be treated in a hanging manner. The yarn can be treated in a knit-denit mode, and a product such as a shirt can be treated in a hanging state or in a state where the product is stretched flat and laminated. The textile product can be processed not only in a free state but also in a pressed state or a tension set state. However, according to the present invention, it is characterized in that a high-temperature steam can be sufficiently penetrated into and brought into contact with tightly packaged fiber products such as cheeses and beams. It is particularly suitable for application to textile products in form.

FIG. 1 shows an example of an apparatus for stabilizing the form of a fiber product used in the present invention. In the figure, reference numeral 1 denotes a vertical closed treatment tank in which a fiber product 3 in which a yarn is wound around a perforated tube 2 and packaged in a cheese shape is stacked in a multi-stage on a perforated cylindrical spindle 4. It is designed to be loaded in a state where it is held in a double manner (8 levels in the figure). In addition, 5 is a cheese receiving stand, 6 is a cheese holding plate, and 7 is a nut for holding and tightening the cheese.

A steam inlet 8 is provided at one location on the lower side of the processing tank 1, and a steam introducing pipe 9 extending from outside the processing tank 1 is provided with a steam introducing valve 10 and an opening control valve 11. And are connected through. 12 is a pressure gauge, 13
Is a mist separator for removing mist from high-temperature steam. In addition, reference numeral 14 denotes a processing tank 1 from the steam inlet 8.
This is a vapor diffusion plate for uniformly sending out high-temperature steam introduced into the inside in the circumferential direction.

Incidentally, the steam introduction valve 10 is connected to the temperature control means 1.
5 is opened and closed in response to an instruction from 5. That is, a predetermined form stabilization processing temperature is input and set in advance to the temperature control means 15, and is set based on temperature data input over time from a temperature sensor 16 provided in the processing tank 1. If the temperature is reached, the steam introduction valve 1
0, and when the temperature falls below the set temperature, the steam introduction valve 10
To open it.

The lower part of the spindle 4 is connected to a steam discharge pipe 17 extending from the bottom of the processing tank 1 to the outside, and is operated by operating a steam discharge valve 18 and an opening control valve 19. The high-temperature steam in the processing tank 1 can be discharged from the steam discharge port 20. In addition, 21 is a deaeration valve.

On the other hand, a drain pipe 24 having a steam trap 22 and a drain valve 23 is connected to the bottom of the processing tank 1. In addition, a pressure gauge 25 is provided above the processing tank 1.
And a pressure adjusting pipe 27 provided with a safety valve 26.

Using the above apparatus, the form stabilization treatment of the textile 3 can be performed, for example, as follows.
That is, first, steam is introduced into the treatment tank 1 from the steam introduction pipe 9 and preheated at a normal shape stabilization treatment temperature or higher. This is performed in order to prevent dew condensation on the wall surface in the processing tank 1 and the inner peripheral surface of the pipe. When the processing is repeated, only the first time is performed, and the second and subsequent times need not be performed. In some cases, it is not always necessary.

Next, the fiber product 3 is loaded into the processing tank 1. Then, the steam introduction valve 10 and the steam discharge valve 18 are both opened, and high-temperature steam (for example, saturated steam at 180 ° C.) is introduced from the steam introduction pipe 9 to heat the inside of the processing tank 1. Note that the opening degree control valves 11 and 11 are set so that the amount of introduced steam is slightly larger than the amount of released steam and that the amount of used steam can perform the shape stabilization processing without excess or deficiency. 19 is adjusted in advance.

When the temperature in the processing tank 1 measured by the temperature sensor 16 reaches a predetermined form stabilization processing temperature which is set in advance by the temperature control means 15, the steam discharge valve 18 is opened. , Only the steam introduction valve 10 is closed. Further, when the temperature in the processing tank 1 falls below the set temperature due to excessive release of steam, the steam introduction valve 10 is again opened, and the temperature in the processing tank 1 recovers to the set temperature. By repeating this series of operations for a time set in the temperature control means 15 in advance by a timer (morphological stabilization processing time, for example, 5 minutes), the processing is completed.

Simultaneously with the completion of the treatment, the steam introduction valve 10 is closed, the deaeration valve 21 is opened, and the inside of the treatment tank 1 is deaerated. After the inside of the processing tank 1 is returned to normal temperature and normal pressure, the lid of the processing tank 1 is opened, and the loaded fiber product 3 is taken out. In this way, the fiber product 3 can be subjected to the form stabilization processing.

According to this method, the high-temperature steam introduced into the processing tank 1 is discharged from the steam discharge valve 18.
High pressure of high temperature steam (for example, steam pressure of 180 ° C. =
Due to the pressure difference between 9.2 kg / cm ² ) and the atmospheric pressure, a moving flow toward the vapor outlet 20 is inevitably formed,
The high-temperature steam moves in the processing tank 1 as shown by arrows in FIG. For this reason, high-temperature steam is forcibly penetrated from the outside to the inside of the textile product 3, and the textile product 3
Even if the cheese is wound at a high density, the high-pressure steam can sufficiently penetrate into the inside, and a uniform shape stabilization treatment can be performed.

Therefore, the fiber product 3 treated by the above method is subjected to uniform shape stabilization treatment in any part, and is excellent in wrinkle resistance, shrink resistance, etc., strong in stiffness, and excellent in texture. Product 3.

Although the apparatus shown in FIG. 1 is set so that high-temperature steam passes from the outside to the inside of the fiber product 3 packaged in a cheese shape, the steam inlet 8 is provided.
By reversing the arrangement of the steam outlet 20 and the steam outlet 20, it may be set so that the high-temperature steam passes from the inside to the outside of the textile product 3. Also, there is no problem if the display is alternately switched from outside to inside and inside to outside. However, in the case of inside → outside, if the separation and removal of the drain mist generated in the steam introduction pipe 9 is not performed completely as much as possible,
May cause wetting of the inner layer, and may hinder uniform heat treatment. Therefore, unless the inside → outside or the remarkable effect by the switching can be expected, basically, the setting is made such that the high-temperature steam passes from the outside to the inside of the textile product 3 as in the apparatus of FIG. It is desirable to do.

The heating temperature during the morphological stabilization treatment is appropriately set depending on the material and morphology of the fiber product 3, the degree of the intended treatment, and the like. When processing, 150-200 ° C,
When processing fibers mainly composed of animal fibers, 12
It is set to about 0 to 180 ° C. And the processing time,
It is set appropriately, but is usually set to about 2 to 10 minutes.

Further, in the above apparatus, the inside of the processing tank 1 is
In order to maintain a predetermined temperature, a temperature sensor 16 is provided in the processing tank 1 and temperature control is performed based on the temperature data. However, instead of the temperature sensor 16, a pressure sensor is used.
The pressure in the processing tank 1 may be controlled to be constant. That is, the steam pressure is uniquely determined by the temperature.

As an operation for keeping the temperature (or pressure) in the processing tank 1 constant, in the above-described apparatus,
With the steam discharge valve 18 kept “open”, the steam introduction valve 10
Is controlled to open and close. Conversely, the steam introduction valve 1 is controlled.
The steam release valve 18 may be controlled to open and close while 0 is kept “open”. Alternatively, the opening and closing of both valves 10 and 18 may be controlled appropriately.

In the above-described apparatus, the mist separator 13 is provided in the middle of the steam introduction pipe 9 so that mist is not brought into the processing tank 1. Is not necessarily used.

In the above apparatus, the steam discharge valve 1
A steam waste heat recovery means may be connected to recover the waste heat of the steam released from 8. By collecting and reusing waste heat, processing costs can be further reduced.

In the above-described apparatus, a decompression pipe may be connected to the processing tank 1 so that the pressure in the processing tank 1 in which the fiber products 3 are loaded is reduced prior to the form stabilization processing. That is, by pre-pressurizing the inside of the treatment tank, the shape stabilization treatment can be uniformly performed in a shorter time, and the oxidation of the fiber can be effectively prevented.
When the above-described pressure reduction is performed, the degree of vacuum in the processing tank 1 is set to 1
It is preferable to set to about 0 ^{-1 to} 100 Torr.

Further, in the above apparatus, the processing tank 1 is of a vertical type, but the processing tank 1 may be of a horizontal type. The method and mode of loading the fiber product 3 into the processing tank 1 are not limited to those described above, and can be appropriately set.

The present invention can be used in combination with various known techniques such as a technique using superheated steam in a certain temperature range instead of saturated steam.

Next, an embodiment will be described.

[0036]

EXAMPLE 1 Using the apparatus shown in FIG. 1, the following textiles were subjected to a morphological stabilization treatment in accordance with the above-mentioned treatment operation. However, the specific processing conditions are as follows.

[Conditions of textile products]-Kind of thread: 100% cotton-Count: 30/2-Form: Cheese-like package-Weight: about 1 kg / piece-Number of stacking steps: 8-Winding density: 0.35

In order to evaluate the treatment effect of the fiber product (cotton yarn) thus treated, an inner layer portion of cheese
A 20 cm long yarn was cut from each of the middle layer portion and the outer layer portion, and the strength and elongation of each yarn were measured, and an average value of 10 times was obtained. As a control, a 20 cm long yarn was arbitrarily cut from untreated cheese, and the strength and elongation of the yarn were measured.
The results are shown in Table 1 below.

[0040]

[Table 1]

From the above results, it is understood that the yarn of Example 1 hardly deteriorates due to the heat treatment in both the elongation and the elongation, and that the yarn is uniformly treated over the inner, middle and outer layers.

[0042]

EXAMPLE 2 Using the apparatus shown in FIG. 2, a fiber product (beam-shaped woven fabric) described below was subjected to shape stabilization in the same manner as in Example 1 above. The specific processing conditions are as follows.

In this apparatus, a beam-shaped fiber product 31 formed by winding a woven fabric around a perforated beam core 30 having a horizontal processing tank 1a is loaded in a state where it is held sideways by a cart 32. ing. 33 is a loading / unloading rail provided in the processing tank 1a, and 34 is
This is a vapor diffusion plate that has both uniform diffusion of vapor and prevention of condensation drain fall. Otherwise, the configuration is the same as that of FIG. 1, and the same portions are denoted by the same reference numerals and description thereof will be omitted.

[Conditions of fiber products]-Type of fiber: 100% rayon-Woven structure: twill-Dimensions of woven fabric: 1200 mm wide x 50 m long-Form: beam-shaped package-Weight: 200 g / m-Gross weight: 10.0 kg-winding density: 0.42

[Conditions for form stabilization treatment]-Flow direction of steam: from outside to inside of fiber product-Type of steam: saturated steam at 180 ° C-Heating condition: 180 ° C x 5 min-Amount of steam used: 8 kg / batch (0 0.8 kg / fiber 1 kg)

In order to evaluate the treatment effect of the fiber product (woven fabric) thus treated, an inner layer portion of the beam,
A predetermined dimension (100 mm) from each of the middle layer and the outer layer
× 100 mm) fabric was cut out, and the washing shrinkage of each fabric was measured. Further, as a control example, the cloth was cut out in the same manner from the untreated beam, and the same measurement was performed.
The results are shown in Table 2 below. The washing shrinkage of the fabric was measured according to JIS L0217♯103 double dry method.

[0047]

[Table 2]

From the above results, the dough of Example 2 was
It can be seen that the shrinkage-preventing effect is excellent in both wefts and that the treatment is uniformly performed in the inner, middle and outer layers of the beam.

[0049]

As described above, according to the method of the present invention, high-temperature steam is continuously or intermittently introduced into the treatment tank and is discharged continuously or intermittently. Utilizing a pressure difference between the pressure and the atmospheric pressure, a moving flow of high-temperature steam is formed, and this is forced to pass through the inside and outside of the textile product. Therefore,
Even if the fiber product is packaged at a high density, the high-pressure steam can sufficiently penetrate into the interior, and a uniform shape stabilization treatment can be performed. Moreover, according to this method, there is an advantage that the treatment can be performed at a low cost with a very short time and a small amount of steam.

According to the apparatus of the present invention, the above method can be implemented simply and efficiently.
