Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is capable of efficiently removing so-called stains such as ink marks, oil, rust, and the like, such as marks of chaco that are attached to cloths such as clothes, without causing ring stains. The present invention relates to a removing method and a stain removing device.

[0002]

2. Description of the Related Art Conventionally, for example, in the sewing process of clothes, a cloth is marked with chaco, a marker, ink or the like to mark a place where various processes such as cutting of a cloth to a pocket mouth and a button hole are performed. According to this, a predetermined processing work is performed.

On the other hand, in the processes such as sewing and finishing, oil such as a sewing machine and impurities such as rust often inadvertently inevitably adhere to the fabric and cause stains.

As described above, in each step of sewing processing of clothes, not only the marks made on the cloth but also the spots attached to the cloth by carelessness reduce the commercial value,
Since it becomes unnecessary stains, it must be removed cleanly without leaving a mark.

Conventionally, in order to remove this stain, a stain removing device 1 as shown in FIG. 5 is generally adopted. Although not shown, the stain removing device 1 is a stain removing device main body 1 in which a mechanism such as a compressor and a suction motor is incorporated.
On the upper surface of a, a support base 2 on which a cloth is applied, such as a horse stand or a flat stand, is arranged.

The support base 2 is provided with a porous region 3 in which a large number of holes 3a, 3a, ... Are provided on the upper surface of the support base 2, and the porous region 3 passes through the inside of the support base 2. It is connected to a suction motor built in the stain removing device main body 1a.

On the upper side of the support base 2, a lever 4a is provided.
A spray gun 4 for a solvent for injecting a cleaning liquid of a solvent such as a chlorofluorocarbon-based gas through a drawing pipe 4b connected to a compressor built in the stain removing device main body 1a by the operation of The spray gun 4 is suspended by a support rod 6 erected on the stain removing device main body 1a via a spring body 6a and the like so that the spray gun 4 can freely come into contact with and separate from the support rod 6.

Similarly, when the lever 5a is operated, the spray gun 5 for spraying cleaning water or the like in a mist state through the draw-out pipe 5b connected to the compressor is attached to the support rod 6 by the spring body 6b or the like. It is hung so that it can come and go freely.
In addition, 7 is a receiving stand, and 8 is a placing stand on which a solvent or the like is placed.

[0009]

By the way, in the conventional stain removing device 1 as described above, the spray gun is applied after the cloth 10 of the portion having the stain 9 is applied to the porous region 3 of the support base 2. The stain removal work is carried out by spraying mist-like cleaning liquid and cleaning water onto the stains 9 from a close distance by 4, 5 and hitting them on the stains 9.

Simultaneously with this spraying, the support portion 2 and the porous region 3 are constructed so that the spots 9 struck by the spray guns 4 and 5 are vacuumed toward the lining side of the fabric 10 by the suction force of the suction motor. Has been done.

FIG. 6 is an explanatory diagram showing this basic operation.
Is a compressor, and M is a suction motor. Explaining this in detail, as shown in FIG. 7, the stains 9 are applied from the attachment surface side (outer surface side) 10a of the cloth 10 to the opposite surface side 1 thereof.
0b, that is, the method of removing by tapping to the lining side, is an application of the old-fashioned conventional stain removal technique, in which dirt is tapped from the top to the bottom of the cloth using a device called "Sasara". is there.

However, in such a stain removing method, the stains 9 adhering to the cloth 10 must be passed through the cloth 10 and extracted from the lining side, resulting in poor efficiency and almost perfection. There are drawbacks that stains cannot be removed and so-called ring stains occur.

Therefore, in the conventional stain removing device, the spray guns 4 and 5 are modified so as to increase the ejection force, a strong solvent is used, or the suction force of the porous region 3 of the support base 2 is increased. It has to be remodeled, which is inevitably expensive.

As long as the method of passing the stains 9 through the cloth 10 and extracting from the lining side is followed in this way, even if the stain removing device is variously modified, almost perfect stains cannot be removed and the ring stains are not removed. Occurrence cannot be prevented. Moreover, CFC-based gas, which is effective as a solvent, has environmental problems, and there are many problems to be solved, such as the prohibition of its use in the near future.

On the other hand, as a result of various studies on the cause of the ring stain, the present inventors extract the stains 9 from the adhering surface side (outer surface side) 10a of the cloth 10 to the opposite side (lining side) 10b as described above. The method was confirmed to be due to the spread of spots. As a result of various experiments and researches, a stain removal method that prevents the spread of stains and does not cause ring stains and a stain remover have been developed, and the stain remover according to Japanese Patent Application No. 5-250042 (unpublished) has already been developed. Proposed method and stain remover.

According to this patent application, air of a predetermined temperature is jetted from a porous region of a support portion such as a horse portion on which the side opposite to the stain adhering surface (lining side) of the cloth is applied by an jetting mechanism.
The gist is a structure that sprays cleaning water (cleaning liquid) from the stain-attached surface side by a spraying / vacuum mechanism to promote the removal of stains and suctions from the stain-attached surface side to remove stains and cleaning water (cleaning liquid). .

However, in this patent application, since air is jetted from the porous region of the supporting portion, that is, from the lining side of the fabric,
The fabric moves, lacks stability, reduces work efficiency, and makes accurate stain removal difficult. In addition, it was confirmed that the spots diffuse due to the capillary phenomenon and ring spots occur.

The present invention was created in view of such circumstances, and various stains adhering to a cloth or the like can be efficiently removed without causing ring stains and a stain removing device. The purpose is to provide.
