Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flexible garment having a convex braille that enables a visually impaired person to easily recognize information on handling of the garment, and a convex braille pattern that can be bent and deformed using a transfer label. The present invention relates to a method of manufacturing garments that can form only garments on the garment surface.

[0002]

2. Description of the Related Art Braille that a visually impaired person can recognize by touching it with a hand is not only directly formed on a metal or plastic frame like an electric product but also on a pedestrian crossing or a station staircase formed by a sheet having braille-shaped projections. Affixed to the handrails of the company. In recent years, catalogs and technical literature have also included prints in which convex braille is overprinted using transparent ink on ordinary prints.These prints have been applied to not only sighted persons but also visually impaired persons. The times are changing to convey the information of.

[0003] At present, clothing such as sports shirts and blouses is generally a soft and changeable material, so that there are almost no products provided with convex Braille. However, even for the visually impaired, the color and shape of clothing are important factors when purchasing products, and it is necessary to obtain information such as the quality and how to wash the clothing when washing after use. .

[0004]

In order to attach Braille to clothing, a heat-sensitive adhesive is applied to the back of a sheet-like label provided with a convex Braille, and the label is ironed onto the clothing surface. May adhere. When the entire surface of the sheet is adhered to the clothing surface as in the case of this label, the clothing becomes difficult to bend partially, particularly in thin clothing such as underwear and shirts, and the wearing comfort is greatly reduced. In addition, if such a label sheet is present on the back side of the clothing, the label sheet may come into contact with the skin of the visually impaired or sighted user as a user or other clothing, thereby damaging the skin or fuzzing the other clothing. .

The present invention has been proposed in order to improve the above-mentioned problem when forming a convex braille on clothing, and the comfort of clothing does not deteriorate, and a visually impaired person can use various information. It is an object of the present invention to provide a garment having Braille that can easily recognize the garment. Another object of the present invention is to provide a method of manufacturing a garment having braille in which only a convex braille pattern that can be bent and deformed is formed on the garment surface, not only for clothing before sewing but also for existing clothing. It is.

[0006]

In order to achieve the above object, clothing according to the present invention is flexible clothing such as outer garments, shirts, underwear and hats. Has a series of recognizable convex braille on the garment surface. The convex braille can be bent and deformed together with the garment, and a short fiber group is densely planted on a braille adhesive binder layer fused to the garment surface to form a pattern. Also,
The Braille may be formed by a resin layer raised on a Braille adhesive binder layer fused to the clothing surface.

The manufacturing method according to the present invention is a method for manufacturing a garment having a convex braille that can be bent and deformed, in which short fibers are densely implanted on the surface of a peelable sheet via a temporary adhesive layer. A transfer label made of a flocked sheet is used. In the production method of the present invention, a transfer label formed of a resin sheet obtained by applying a reactive resin to the surface of a peelable sheet via a temporary adhesive layer may be used.

In this manufacturing method, a predetermined reverse Braille pattern is printed with a liquid adhesive binder on the flocking surface or the resin surface of the transfer label, and particles of the thermoplastic resin are dispersed in the adhesive binder in advance. . The thickness of the adhesive binder layer becomes 30 to 100 μm by drying. The transfer label is formed by printing a predetermined reverse Braille pattern on the flocking surface or the resin surface with an adhesive binder to a dry thickness of 20 to 50 μm, and further sprinkling thermoplastic resin particles on the adhesive binder layer. May be adhered to a reverse braille pattern and then dried and fixed.

In the above transfer label, when printing a liquid adhesive binder in a reverse Braille pattern, the gap between 50 inches and 50 inches is used.
It is preferable to use a screen plate made of a screen gauze of polyester monofilament which is 100 meshes. By using such a screen plate, reverse Braille patterns can be printed accurately on the screen.

According to the production method of the present invention, a flocked sheet or a resin sheet is used as a transfer label, and only a reverse Braille pattern composed of an adhesive binder layer is transferred to a predetermined portion of clothing by heating and pressing. In the resin sheet, the reactive resin layer is partially peeled at the time of transfer and is cured by causing a crosslinking reaction or the like by heating.

[0011]

BEST MODE FOR CARRYING OUT THE INVENTION The clothing according to the present invention has a series of convex Brailles 2 on a part of its surface from which various information can be recognized. This garment is flexible such as a shirt such as a sports shirt 1 (FIG. 1) or a shirt, an outer garment, an undergarment or a hat, and can be applied to a cloth handkerchief, a furoshiki, a bag, and the like. The display position of the series of convex brailles 2 provided on the clothing surface is on the front side or the back side of the clothing, and it is necessary to determine in advance an effective place in consultation with a visually impaired organization or a regulatory agency.

A series of Braille 2 discloses how to handle and wash the shirt 1, as shown in FIG.
A short fiber group 5 is densely planted and formed on an adhesive binder layer 3 having a braille pattern fused to the surface of clothing. Short fiber group 5
Is made of rayon, nylon, polyester fiber or a mixed fiber thereof, and glass fiber or metal fiber may be used. Basically, the short fiber group 5 is white and the adhesive binder layer 3 is transparent.
Also, the adhesive binder layer can be colored. For example, a black short fiber group 5 is used for black clothing.

A series of convex brailles 2 that can be bent and deformed as shown in FIG. 2 are formed using a transfer label 7 illustrated in FIG. To manufacture the transfer label 7, commercially available flocking paper, flocking film, flocking sheet, or
As shown in (1), first, a temporary adhesive having a low adhesive force is applied on the peelable sheet 8, and a temporary adhesive layer 10 is provided on the entire surface of the sheet.

Examples of the peelable sheet 8 to be used include a plastic film, paper, cloth, and nonwoven fabric.
In the case of paper, cloth, or nonwoven fabric, it is preferable to laminate or impregnate a resin having a higher melting point than the temporary adhesive layer 10. In the temporary adhesive layer 10, the adhesive having a low adhesive strength is
Acrylic, vinyl acetate, vinyl chloride resins, casein, carboxymethylcellulose, starch, etc. that are dispersed in water, even if glycerin, ethylene glycol, polyethylene glycol, kaolin powder, etc. are added to adjust transplantability Good.

In FIG. 5, short fibers are densely implanted on the temporary adhesive layer 10 by an electrostatic flocking method or the like, and a short fiber layer 11 is formed.
Is obtained. The electrostatic flocking method uses rayon, nylon,
Short fibers such as polyester are scattered, and the releasable sheet 8 provided with the temporary adhesive layer 10 is brought close to the electrode plate. When the sheet 8 is connected to the negative electrode, the short fibers are
Since it is absorbed to zero, it is dried and then unnecessary fibers other than the printing surface are wiped off.

Next, as shown in FIG. 6, by printing with a liquid adhesive binder 14 on the flocking surface of the flocking sheet 12, the bonding binder layer 3 having a predetermined reverse Braille pattern is formed. The adhesive binder layer 3 can be formed by any of offset printing, gravure printing, letterpress printing, and the like. However, it is usually preferable to provide a relatively thick layer by screen printing.

The screen plate (not shown) used in the screen printing is preferably made of a polyester monofilament screen gauze having a mesh of 50 to 100 meshes per inch. The screen plate is fixed by placing a screen gauze on an aluminum frame or a wooden frame and pulling it around four times using a tensioner. In this screen printing,
A liquid adhesive binder is placed inside the screen plate either manually or automatically, and is pushed out below the screen gauze by a squeegee (not shown).

The liquid adhesive binder 14 is obtained by adding a thermoplastic urethane-based, acrylic-based, vinyl acetate-based, vinyl chloride-based resin or the like to an organic solvent, and the obtained adhesive binder layer 3 is more adhesive than the temporary adhesive layer 10. Power is great. Adhesive binder 1
In 4, thermoplastic resin particles are dispersed in advance, and the resin particles are made of a thermoplastic polyamide-based, ethylene-based, or vinyl chloride-based resin. The resin particles
When the particle diameter is 30 to 100 μm, the short fiber group 5 is firmly adhered to the clothing surface because the short fiber group 5 is easily melted by entering between short fibers and the texture of the clothing during transfer.

After forming the adhesive binder layer 3 by screen printing, the adhesive binder layer is sufficiently dried. By this drying, the thickness of the adhesive binder layer 3 is 30 to 100.
μm. At this time, the thickness of the adhesive binder layer 3 is 30
If it is less than μm, sufficient adhesive strength cannot be obtained,
When the thickness exceeds 00 μm, it is uneconomical, and it is protruded to four rounds at the time of transfer, so that the Braille is easily deformed.

The obtained transfer label 7 is turned over as shown in FIG. 7 and pressed against the clothing surface.
What is necessary is just to heat-press at kg / cm ² for 10 seconds. As a result, the adhesive binder layer 3 is fused to the clothing surface, and the short fiber layer 11 of only the reverse Braille pattern portion of the adhesive binder layer is peeled off.
The short fiber group 5 is adhered to the clothing surface in a Braille shape. The portion of the short fiber layer 11 where the adhesive binder layer 3 does not exist does not adhere to the clothing surface, and a series of Braille 2 is formed by the transfer label 7 as shown in the figure. Both of the sheets are peeled off.

In the garment of the present invention, only the small-area Braille 2 is formed on the garment surface, and since the Braille 2 can be bent and deformed by the short fiber group 5 and the adhesive binder layer 3 of a thermoplastic resin, Comfort does not deteriorate. A visually impaired person can easily recognize various kinds of information on clothing by a series of convex brailles 2. In the method of the present invention, since a series of Braille 2 is formed by the transfer label 7, it is possible to form Braille not only on clothing before sewing but also on existing clothing.

The particles 24 of the thermoplastic resin are not dispersed in the adhesive binder 14 as described above, but are dispersed in FIG.
It may be sprinkled on the adhesive binder 22 immediately after printing as shown in FIG. At this time, the resin particles 24 are made of a thermoplastic polyamide-based, ethylene-based, or vinyl chloride-based resin.
The resin particles 24 have a particle size of 150 to 300 μm, have a relatively large diameter for direct contact with the clothing surface, and enter between short fibers and into the woven fabric of the clothing during transfer, and melt.
The short fiber group 5 is firmly adhered to the clothing surface.

The resin particles 24 are sprinkled on the undried adhesive binder 22 to adhere the particles in a reverse braille pattern, and then sufficiently dried at 40 to 60 ° C. By this drying, the thickness of the adhesive binder layer 23 becomes 20 to 50 μm. At this time, if the thickness of the adhesive binder layer 23 is less than 20 μm, sufficient adhesive strength cannot be obtained, and
If it exceeds, it is uneconomical and tends to protrude to four rounds during transfer. Resin particles other than the reverse braille pattern may be wiped off from the transfer label 20 with a rotating brush or the like, and absorbed with a vacuum device or the like.

In the transfer label used in the method of the present invention, as shown in FIG. 10 or FIG. 11, instead of the flocking sheet 12, a reactive resin layer 38 is provided via a temporary adhesive layer 36 with a release sheet. Resin sheet 4 applied to the surface of 34
0 may be used. Generally, the reactive resin layer 38 is uncrosslinked and brittle when applied to the resin sheet 40, but is cured by a crosslinking reaction or the like caused by heating during transfer.

The reactive resin layer 38 has a thickness of about 16
When heated to 0 ° C., it softens but does not melt, and the portion of the resin layer 38 where the adhesive binder layer 42 does not exist does not adhere to the clothing surface during transfer. If there is a possibility that the reactive resin layer 38 may adhere to the clothing surface even if it is other than the adhesive binder layer 42, a release agent or the like may be sprayed on the resin layer 38.
