Description

  The present invention relates to a method for forming a foil transfer of a metal film or the like on a transfer object such as a fabric.

  In general, the technology of metallic printing on fabric with metallic transfer foil

Widely used including clothing.

  Conventionally, such metallic printing has been performed by heat-pressing a metallic foil on the surface of a woven fabric that is a material to be transferred. Such a metallic foil includes a base film, a release layer formed inside the base film, a protective layer formed inside the release layer, and a metal film formed inside the protective layer. A layer and an adhesive layer formed inside the metal film layer.

  When a metal film is transferred onto a woven fabric using such a metallic foil, an adhesive that forms a printing pattern on the surface of the woven fabric that is a transfer object is formed on the portion where the metal film is to be transferred. Then, the metallic foil is placed on the fabric and heated.

The metal foil is joined to the fabric by melting the adhesive applied to the fabric by the heating and the adhesive layer formed on the metallic foil, and then completed by peeling the base film and the release layer. .
As such a prior art, the present patent applicant has filed the following patent application.
Japanese Patent Publication No. 5-60872

  However, in the technique described in the above-mentioned patent document, a heat-sensitive binder paint is used to form a pattern or character with a metal film by foil transfer on the cloth fabric of a predetermined color. It was necessary to print characters and patterns, place the above-mentioned metallic foil on top of them, and polymerize them by thermocompression bonding. There was a need for technology improvements that further reduced the process of foil transfer and reduced production time and production costs. .

  In addition, in such a conventional method for transferring a metal film, a fabric as a transfer material is colored in advance by printing. In such printing, a drying process, a steaming process, a washing process are performed. I need a process.

  That is, when dyeing with a dye, first add the glue to the dye solution so that the dye of the color to be dyed is melted in water, placed on a fabric, and does not bleed when forming a pattern, etc. Then, increase the viscosity and place it on the cloth, so-called “mold placement”.

  After this “mold placing process”, the process enters a “drying process” where drying is performed for a predetermined time. After this “drying process”, the fabric placed in a high-temperature steam atmosphere in the “steaming process” is placed at a predetermined time. The color paste formed by being left standing and added with the paste is dissolved by moisture and heat supplied from the vapor, and enters the fiber as dye molecules to be dyed. By this “steaming process”, the dye develops color and is fixed to the fabric.

  After that, it enters a “washing process” in which the colored fabric is immersed in water. In this “washing step”, the above-mentioned color paste is peeled off from the fabric, and the residual paste on the fabric surface and unfixed dyes, chemicals, etc. are peeled off. After that, dehydration and drying are performed in a “drying process”, and necessary processes are performed and the inspection process is completed.

  Therefore, when it is intended to produce a foil transfer product by performing foil transfer processing on a cloth colored in a predetermined color and pattern by printing with a dye in this way, the above-mentioned printing process includes a `` drying process '', `` Since the “steaming process”, “cleaning process”, and “drying process” are required, a large number of processes are required until the production of the product by foil transfer as a whole.

  Such a textile printing process is performed by skilled craftsmen when manually performed, and when performed at a textile factory, the textile printing process is performed by an automatic screen printing apparatus or a mechanical textile printing apparatus. In addition, since it is necessary to install a roller device, a rotary device, etc., and a large-scale facility is required, it takes time to create a foil transfer product, and the manufacturing cost related to the printing process increases. There was a problem that.

  Therefore, the problem of the present invention is that the above-described printing process is not necessary, the time to complete the foil transfer product can be reduced, the manufacturing cost can be reduced, and the foil transfer process can be shortened, The object is to provide a metal film transfer method capable of reducing the manufacturing cost of a foil transfer product as a whole.

  In order to solve the above problems, the present invention provides a method for forming a transfer foil in which a transfer foil is transferred to a transfer object by heat-pressing the transfer foil to the transfer object, and a pigment is applied to the transfer object. Then, foil transfer is performed.

  Therefore, in the present invention, the transfer foil is formed on the transfer object by heat-pressing the transfer foil to the transfer object coated with the pigment.

  Further, in the present invention, the upper transfer object is a fabric, and the pigment is applied to the fabric via a plurality of different types of binders, and the portion forming the foil transfer pattern of the fabric A pigment having an acrylic resin as a binder is applied, and a pigment having ethyleneimine as a binder is applied to a portion where the foil transfer pattern is not formed.

  Accordingly, in the present invention, the transfer foil is bonded to the fabric by the binder made of acrylic resin applied to the portion forming the foil transfer pattern of the fabric.

  Further, in the present invention, an acrylic resin-mixed pigment application step of applying a pigment containing an acrylic resin as a binder to a portion where a foil transfer pattern is to be formed on the fabric, and ethylene on the portion of the fabric where the foil transfer pattern is not formed Applying an ethyleneimine admixture pigment application step of applying a pigment containing imine as a binder, and heating the paste to a temperature at which the acrylic resin can be melted and bonded to the transfer foil, the transfer foil is pressure-bonded to the fabric to form the transfer foil. It has the transfer foil heat press-bonding process joined only to the pigment containing the said acrylic resin, and the peeling process which peels the said foil transcription | transfer.

  As a result, in the present invention, the transfer foil is bonded to a molten acrylic resin binder in the above-described transfer foil thermocompression bonding step. In addition, in the part where the pigment mixed with ethyleneimine is applied, it is not joined to the transfer foil, so that only the metal film in the part where the pigment mixed with ethyleneimine is applied is peeled off in the peeling step. The As a result, a fabric in which a metal film is formed only on a site where a pigment mixed with an acrylic resin is applied is created.

  In the present invention, the acrylic resin binder is melted at 150 ° C. and the ethyleneimine binder is melted at 180 ° C., and the transfer foil thermocompression bonding step is performed in a temperature environment of 150 ° C. It is characterized by.

  As a result, in the transfer foil thermocompression bonding step, the acrylic resin binder and the transfer foil are melted and bonded to each other because they are crimped at a heating temperature of 150 ° C., while the pigment mixed with ethyleneimine Since it does not melt at 150 ° C., it does not melt and bond with the metal film, and is peeled off in the peeling step.

  In the present invention, the transfer foil is bonded to the base film, a release layer capable of peeling the base film, a protective layer for protecting the foil portion, the foil layer, and the adherend-side binder. And a bonding layer to be obtained.

  Therefore, in the present invention, when the thermocompression bonding is performed in the transfer foil thermocompression bonding step, the bonding layer and the fabric side binder are bonded, and in the peeling step, the base film and the peeling layer are peeled off. The protective layer and the foil layer remain bonded together with the bonding layer on the adherend side to form a transfer foil.

  In the present invention, the foil layer is made of a metal film. Further, the foil layer is made of a pigment.

  Therefore, as in the conventional case, when performing a foil transfer process on a fabric colored in a predetermined color and pattern by printing with a dye to create a foil transfer product, when coloring the fabric as a transfer object, As the above-mentioned textile printing process, it is possible to shorten the working time relating to the “drying process”, “steaming process”, “washing process”, and “drying process”.

  In addition, work by skilled craftsmen when performing such printing work manually, and when performed in a printing factory, printing work is performed by an automatic screen printing apparatus or a mechanical printing apparatus. In addition, it is necessary to install a rotary device or the like, and it is possible to reduce the production cost resulting from the need for a large-scale facility.

  Further, in the present invention, an acrylic resin and ethyleneimine having different melting temperatures are used, an acrylic resin that melts at a lower temperature than ethyleneimine is mixed into the pigment as a binder, and at a higher temperature than the acrylic resin. Since the part that does not form foil transfer is applied with a pigment mixed with melting ethyleneimine, by setting the temperature setting at the time of thermocompression bonding to the temperature at which the acrylic resin melts, the pigment mixed with the acrylic resin easily The foil transfer can be performed only at the site where the coating is applied.

  Furthermore, in the present invention, as in the prior art, it is not necessary to draw a pattern or characters with a paint mixed with a binder on a colored fabric that performs foil transfer, and to perform foil transfer from above, Since the fabric coloring and the foil transfer can be simultaneously performed, the manufacturing process of the foil transfer product can be greatly reduced, and the manufacturing cost can be reduced.

Hereinafter, the present invention will be described in detail based on embodiments shown in the accompanying drawings.
In the metal film transfer method according to the present embodiment, as shown in FIG. 1, an acrylic resin-containing pigment application step 10 for applying an acrylic resin-containing pigment to a site where a pattern is formed on the fabric, and the fabric An ethyleneimine-containing pigment application step 11 for applying an ethyleneimine-containing pigment to a portion where the pattern is not formed, and a pigment containing the acrylic resin containing the metal film by pressing the metal film against the fabric in a heated state And a peeling step 14 for peeling the metal film placed on the portion coated with the pigment containing ethyleneimine.

  In the method for transferring a metal film according to the present embodiment, a pigment is used as a paint to be applied to a fabric on which foil transfer is performed.

  Here, the term “pigment” is used as a general term for all color materials that are not water-soluble, and includes both inorganic pigments and organic pigments. In actual use, a binder (adhesive) is mixed with an inorganic pigment or organic pigment formed into a fine powder, processed into a fiber, and fixed to the fabric surface. As the inorganic pigment, for example, type yuzen used corn flour as a white paint, but in recent years titanium oxide has been used.

  In addition, the organic pigments are often made from the same pigment as the dye, and various colors are prepared. As the adhesive for fixing the pigment to the fabric, a natural or synthetic resin is used.

  Also, when applying pigment to fabric, it is mixed with adhesive and placed on the fabric, but the placed pigment and adhesive do not enter the fiber and cover the fiber surface as a film. This point is different from the case of coloring with a dye.

  Furthermore, when coloring with dye, it is necessary to select the dye to be used according to the kind of fiber material of a cloth person. For example, an acid dye or an acid mordant dye is used for animal fibers such as silk, wool, and nylon, and a disperse dye is used for synthetic fibers such as acetate, tetron, and polyester.

  However, in the case of a pigment, there is no compatibility with a raw material as in the case of a dye, and it can be used for any fiber. In particular, medium-colored and light-colored pigments have excellent weather resistance compared to dyes, and are extremely tough against physical friction, washing, and chlorine bleaching.

  In the metal film transfer method according to the present embodiment, an acrylic resin is used as the binder. This acrylic resin is formed as a water-soluble resin solution. That is, an acrylic resin is dissolved in a solvent and emulsified and dispersed, and pigment fine particles are dispersed in a muddy or liquid state with a dispersant in the water-soluble resin solution.

  Therefore, in the present embodiment, the portion of the fabric to be foil-transferred and where the foil transfer portion is to be formed is applied with an acrylic resin as a binder and a solution in which an appropriate color pigment is mixed. This may be, for example, a pattern or picture drawn on the fabric or a letter.

  Since the acrylic has a boiling point of about 150 ° C., the pigment containing the acrylic resin as a binder is configured to melt when heated to 150 ° C.

Then, the part other than the part to be foil-transferred onto the fabric is coated with the same pigment mixed using the acrylic resin ethyleneimine as a binder. In this case, the binder made of ethyleneimine has a melting point of 180 ° C. and is configured to melt when heated to 180 ° C. or higher.

  Moreover, the transfer foil 30 used in the foil transfer forming method according to the present embodiment is a metallic foil, and as shown in FIG. 2, a base film 31 and a release layer 32 that can peel the base film 31. And a protective layer 33 that protects the foil layer 33, a foil layer 34 made of a metal curtain, and a bonding layer 35 that can be bonded to the fabric side binder.

The operation of the metal film transfer method according to the present embodiment will be described below.
As described above, when the metal film transfer method according to the present embodiment is performed, first, in the acrylic resin pigment application step, the acrylic resin admixture pigment is applied to the fabric.

  An acrylic resin-mixed pigment is one in which pigment fine particles are dispersed in a muddy or liquid state with a dispersant in a water-soluble resin solution prepared by dissolving and emulsifying an acrylic resin in a solvent. Therefore, in the present embodiment, the acrylic resin-mixed pigment solution is applied to the portion of the fabric to be foil-transferred where the foil transfer portion is to be formed to form characters, patterns, and the like. In the present embodiment, as shown in FIG. 3, the above-mentioned pigment is mixed with characters 22 (characters “OPEN” in the present embodiment) 22 on the fabric 16 forming the banner 15. Draw with acrylic resin solution 23.

  Next, in the ethyleneimine-containing pigment coating process, the coating is applied to a site other than the site coated in the acrylic resin pigment coating process. That is, as shown in FIGS. 3 and 4, an ethyleneimine solution 24 in which a pigment is mixed is applied to the portion of the fabric 16 other than the characters “OPEN” which is the color of the fabric itself.

Thereafter, in the thermocompression bonding step 13, the fabric 16 is wound around the support roller 20, and the transfer foil 30 is pressure-bonded to the fabric 16 on the support roller 20 via the heat roller 18 to perform foil transfer.
The heating roller 18 is provided with a heater device (not shown), and a silicon rubber plate 21 is wound around the outer peripheral edge.

  In this case, since the heat roller 18 is heated to 150 ° C. by a built-in heater device, the transfer foil 30 heated by the heat roller 18 is wound around the support roller 20 in a state heated to 150 ° C. It is crimped to the cloth 16 that has been worn. Since the cloth 16 is coated with a letter with acrylic resin as a binder and applied with foil transfer characters, the acrylic resin as the binder of the acrylic resin solution 23 is also melted at 150 ° C. Melts with foil 30.

  On the other hand, the transfer foil 30 is pressure-bonded to the entire pigment applied on the fabric 16, but the ethyleneimine solution 24 is applied to portions other than the characters 22 so that the ethyleneimine solution melts at 180 ° C. Therefore, unlike the melting temperature of the transfer foil 30, it is not bonded to the transfer foil 30.

  Next, in the peeling step, the transfer foil 30 is removed from the fabric 16. In this case, as shown in FIG. 6, since the bonding layer 35 is melted and bonded to the acrylic resin that is the binder of the pigment that is also melted, the foil layer 34 made of a metal film as an upper layer of the bonding layer. And the protective layer 33 remain on the fabric 16 side, and the release layer 32 and the base film 31 are peeled off.

  As a result, a foil layer made of a metal film is formed on the “OPEN” character 22 of the fabric 16 by bonding, thereby completing the foil transfer.

  As a result, in the present embodiment, since the foil layer 34 is formed of a metal film, a glossy metal film is formed on the letters “OPEN”, and the pigment of the ethyleneimine solution 24 is formed. The character by the said glossy metal film floats on the color used as the background of the apply | coated fabric, and can increase a visual effect.

  Moreover, in this Embodiment, although the case where a foil layer consists of a metal film was demonstrated to the example, it is not limited to the said embodiment, The foil layer may be formed with the pigment.

  In the present embodiment, the case where the fabric 16 is formed as a banner has been described as an example. However, the present invention is not limited to the above-described embodiment, and may be, for example, a banner, a flag, and the like. Any product that needs to appeal to visual effects can be applied.

  Further, in the present embodiment, the “roll method transfer method” in which the fabric 16 as the transfer object is wound around the support roller 20 and the transfer foil 30 is pressure-bonded to the fabric 16 by the heating roller 18 has been described. Without being limited to the above-mentioned embodiment, it is an “up-down method” in which a cloth is placed on a support base and lowered by a vertical plate from above to press a transfer foil against the cloth. Also good.

  In the present embodiment, the case where the transfer object is a fabric has been described as an example. However, any material that can withstand the thermocompression bonding step may be used, and the material is not limited to the fabric.

  The transfer foil forming method according to the present invention can be widely applied to products that need to appeal to the visual effect in advertising, such as banners, banners, banners and the like.
