Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flocking method for flocking short fibers on the surface of a substrate such as an iron plate, wood or plastic.

[0002]

2. Description of the Related Art Conventionally, this type of flocking processing method involves applying electrostatic coating on the surface of a substrate and then spraying short fibers on it.
It was performed by a method of mixing short fibers with a liquid of a fluorocarbon high volatility agent and spraying.

[0003]

However, all of these methods require forced drying in a drying room or the like, so that the size of the substrate is limited and the equipment cost is enormous. In addition, the method of spraying short fibers on the electrostatic coating is troublesome, and when using a CFC-based high volatility agent, there is a pollution problem, and since the drying is fast, the short fibers are sprayed uniformly. Requires skill.

Therefore, an object of the present invention is to provide a method for flocking that can be naturally dried, has no restriction on the area of flocking, and can be easily flocked.

[0005]

In order to achieve the above-mentioned object, the method of flocking processing of the present invention is to apply a pressure-sensitive adhesive which is cured by drying to the surface of a substrate, and to blow a short fiber at high speed when the pressure-sensitive adhesive is not cured. It is characterized in that it is blown with low-pressure air, and the short fibers are planted in the pressure-sensitive adhesive to cure the pressure-sensitive adhesive.

[0006]

[Operation] According to the above method, short fibers are blown with low-pressure air that blows at high speed, so that the short fibers pierce the uncured adhesive in an upright state, and when the adhesive cures by drying, a good flocked state is obtained. Become.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in more detail below with reference to the embodiments shown in the drawings.

As shown in FIG. 2, the flocking method of the present invention first uses a water-based adhesive as a pressure-sensitive adhesive that is cured by drying in a conventional spray coater 2 on the surface of a substrate 1 such as an iron plate, wood, or plastic. Spray paint with oil paint 3.

[0009] Then, when the uncured paint 3, about 0.2kg / cm ² ~1.0kg / cm ² nylon pile at sprayer 5 for injecting the low-pressure air at a high speed jet, the length of such cotton pulverized fibers The short fiber 4 having a size of about 0.1 mm to 5 mm is coated 3
Spray on.

The short fibers 4 blown by the low-pressure air blown at a high speed are jetted in parallel with the blowing direction, pierce the uncured paint 3 in an upright state, and are planted on the paint 3. Then, when the paint 3 is cured by drying, the short fibers 4 that are excessively sprayed by a brush or the like are removed, so that the short fibers 4 are satisfactorily planted in the paint 3.

Therefore, the short fibers 4 can be flocked very easily as compared with the conventional flocking processing method, and the paint 3 can be dried naturally. Therefore, no pollution occurs and no forced drying equipment such as a drying room is used. Therefore, there is no restriction on the area for planting hair, and it is possible to plant hair on the wall surface of a building, which was difficult in the past.
Incidentally, there is no problem in forcibly drying the paint 3 if necessary.

The spraying device 5 is provided with a handle 7 at the rear portion of the barrel 6, a storage tank 8 for the short fibers 4 is detachably provided at the lower middle portion of the barrel 6, and the handle 7 is provided from the rear portion to the intermediate portion of the barrel 6.
The air passage 10 continuous with the air supply pipe 9 formed in is formed, the tip side of the air passage 10 is bent into the storage tank 8, and the tip 10a is opened in the storage tank 8. An outlet passage 11 that opens to the tip of the barrel 6 is formed, and a nozzle 12 that changes the outlet pattern is detachably attached to the tip of the barrel 6.

An on-off valve 13 is provided in the middle of the air passage 10. The on-off valve 13 is opened by pulling a trigger 14, and a hose 13 from a blower (not shown) connected to the handle 7 is provided. A large amount of low-pressure air supplied to the air supply pipe 9 by the air is sent into the storage tank 8 through the air passage 10,
The short fibers 4 in the storage tank 8 are agitated by the low-pressure air that blows at high speed, and the short fibers 4 are jetted from the blowing passage 11.

In the above embodiments, the paint 3 is spray-painted on the surface of the substrate 1 for flocking. However, an adhesive may be used as a pressure-sensitive adhesive which is cured by drying, or spraying is also possible. Not limited to painting, an adhesive may be applied to the surface of the substrate 1 by brush painting, dobu pickling, or the like.

Further, the short fibers 4 are not limited to nylon piles, crushed cotton fibers, and the like, but may be various fibers such as animal fibers, plant fibers, and mineral fibers.

[0016]

As described above, the flocking method of the present invention applies the pressure-sensitive adhesive that is cured by drying to the substrate surface,
When the adhesive is uncured, short fibers are blown with low-pressure air that blows at a high speed, and the short fibers are planted in the adhesive to cure the adhesive, so that the short fibers are upright and pierce the uncured adhesive. When the pressure-sensitive adhesive is cured by drying, a good flocked state is obtained.

Therefore, short fibers can be flocked very easily as compared with the conventional flocking method, and the adhesive can be dried naturally, so that no pollution occurs and no forced drying equipment such as a drying room is used. There is no restriction on the area of flocking,
Hair can be planted on the walls of buildings, which was difficult in the past.
