Description

  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fastener color pattern transfer apparatus and a transfer method thereof, and in particular, a color pattern can be transferred even within a fastener tooth row, and the fastener does not penetrate into the back surface of a base fabric portion. The present invention relates to a fastener color pattern transfer device and a transfer method thereof which are intended to maintain the quality of the fastener.

  Fasteners are mainly made of metal or plastic, and the base fabric part is made of cloth. The fasteners are widely used for clothes, bags, wallets and the like. The base fabric part of such fasteners is often white and plain, and most of them are plain even if they are colored, and the color is also adapted to the coloring of clothes and accessories used. There is no kind of this. For this reason, for example, when the coloring of the clothes and the color of the base fabric portion of the fastener are unbalanced, the appearance may be bad or the fastener portion may be lifted.

In order to prevent such disproportionation, it is desirable that the color of the base fabric portion of the fastener can be colored or colored in accordance with the coloring of clothes or the like, but in the present situation where this is not possible, The problem is solved by hiding the zipper part with the front cloth.
For these reasons, fasteners that can be applied to various colors of products are demanded in the fashion industry and the accessory industry that manufactures bags and wallets. In order to meet this demand, it is only necessary to manufacture fasteners according to the color of the product. However, if fasteners are manufactured for each color of the product, there will be an excessive inventory, resulting in an increase in cost.

  On the other hand, when coloring and patterning are applied to the base fabric part of the fastener, it is possible to apply coloring and patterning by pattern weaving using dyed yarn. It takes time to design and weave, and it must be woven by a specific loom. Therefore, it cannot be profitable unless a large number is produced, and is not suitable for production of a small lot.

Therefore, as disclosed in Patent Document 1, a method for manufacturing a fastener that can be applied to various color patterns of a product and can be easily produced in a small lot is proposed.
According to the method for manufacturing a fastener proposed in Patent Document 1, ink is directly ejected onto the cloth tape portion with the engagement tooth surface of the engaged fastener material and the cloth tape portion positioned on substantially the same plane. A color pattern can be formed on the surface of the cloth tape portion. Thus, since a color pattern can be formed by ink ejection, production of a small lot is also facilitated.

When used, the slider 12 and the upper stopper 14 and the lower stopper 15 are attached by cutting to a predetermined length.

FIG. 2 is a schematic configuration diagram showing a configuration of an apparatus (pattern creating apparatus) for manufacturing a transfer sheet used for forming a color pattern on the fastener 10.
As shown in the figure, the pattern creating apparatus 100 includes an image reading apparatus 101, an image creating apparatus 102, a storage unit 103, and a dye pattern creating unit 104.

  The image reading apparatus 101 reads an original image composed of a monochrome image or a color image as image data. Here, as the image reading apparatus 101, for example, a commercially available personal computer can be used. The original image data to be captured by the personal computer can be image data of various storage formats stored on various media. As the image data in various storage formats, for example, image data taken by a digital camera, image data designed by the author, or an analog image such as a picture printed on a paper or a picture drawn on paper as a digital signal. Image data that has been converted and captured can be listed.

  When the original image is an analog image, the image reading apparatus 101 converts an optical image obtained by an imaging unit including an optical element into a digital signal, performs predetermined signal processing, and converts it into image data. An output device, for example, a film scanner, an image scanner, a copier, or a complex machine of these may be used. In addition to the above, the original image may be image data received via a communication device such as a computer or a mobile phone through a communication network such as an electric communication line or optical fiber communication.

  Hereinafter, an image captured as a digital signal by the image reading apparatus 101 is referred to as a digital image. Examples of file formats of digital images read by the image reading apparatus 101 include so-called JPEG, JTIF, TIF, and the like, and these file formats can be converted to each other as necessary. The image data read by the image reading apparatus 101 is sent to the image creating apparatus 102.

  The image creating apparatus 102 performs image processing necessary for forming a sublimation dye pattern that can be transferred onto a transfer sheet on the digital image read by the image reading apparatus 101. That is, for example, if the digital image is an image that is too dark or too bright, an image that is too strong, an image that is too weak, etc., the image creating apparatus 102 has an appropriate gradation with respect to them and is the lowest. Image adjustment is performed so that the image meets the intended purpose in which the density and the maximum density are appropriate.

  Further, when a sublimable dye pattern is transferred onto a transfer sheet, for example, when a commercially available ink jet printer is used, a color profile suitable for the sublimable dye ink used in the ink jet printer is obtained. Adjust the color to correct the digital image. Appropriate image processing is also performed on the peripheral image combined with the digital image as necessary.

The image creating apparatus 102 preferably includes a display unit (display device). When a display unit is provided, by displaying the digital image and the peripheral image on the display unit, while checking the contents of the digital image and the peripheral image, image selection, image processing combination, correction, etc. It can be carried out.

  The storage unit 103 stores digital image data created by the image creation device 102 and peripheral image data combined with the digital image as necessary. The storage unit 103 includes, for example, an internal storage device or an external storage device. Examples of the file format stored in the storage unit 103 include JPEG, JTIF, TIF, and the like, and these file formats can be converted to each other as necessary.

  The dye pattern creation unit 104 uses the digital image read from the storage unit 103 and its peripheral image, or the digital image directly transferred from the image creation device 102 and its peripheral image, on the transfer paper. Negative pattern). This sublimable dye pattern is preferably an image with the left and right reversed when viewed from the original image. Examples of the dye pattern creation unit 104 include an ink jet printer provided with a sublimable dye ink and a thermal transfer printer provided with a sublimable dye ink ribbon. Note that the dye pattern creation unit 104 may have the functions of both the image creation device 102 and the storage unit 103.

Here, as a formation method when the dye pattern creation unit 104 forms a sublimation dye pattern on the transfer paper, for example, a non-contact inkjet method is preferably used. Hereinafter, a sublimable dye pattern forming method when the ink jet method is used will be described.
In this method, the inkjet head is moved in the XY coordinate plane based on the image information of the digital image, and C (cyan) and M (magenta) are moved from the inkjet discharge nozzle based on the color data of the image information during the movement of the head. ), Y (yellow), and K (black) inks are appropriately ejected to form a sublimation ink pattern on the transfer paper.
In this embodiment, an on-demand ink jet method is shown as the ink jet method, and it is particularly preferable to use a piezo on demand ink jet method.

  The sublimation dye ink is an ink in which a fine sublimation dye is dispersed in a water-soluble solvent. A dispersion stabilizer such as a surfactant is used to prevent aggregation of the dispersed dye fine particles. The ink is preferably used in combination with three primary colors (C (cyan), M (magenta), and Y (yellow)) of the subtractive color method, and K (black) may be used in combination as necessary. Alternatively, Y (yellow) may be used as one color, M (magenta) and C (cyan) may be used as two shades of light and dark, and K (black) may be formed by mixing three CMY colors. Separately, one color of K (black) may be prepared.

  As the sublimation dye, many disperse dyes, some oil-soluble dyes and some basic dyes can be used. The dye used in this embodiment is preferably a nonionic disperse dye because it is required to have a high vapor pressure and good thermal stability. Specifically, the display is based on the color index number, and examples thereof include CIDdisperse Yellow-7, 42, 64, 71, Orange-13, Red-4, 50, 60, 146, 364, Violet-28, Blue-56, and the like. In addition, aminoanthraquinone, indoaniline, quinophthalone, dicyanoimidazole, dicyanomethine, diaminoanthraquinone, dihydroxyanthraquinone, and diaminodihydroxyanthraquinone dyes are effective.

The YMC sublimable dye will be described in detail below.
Examples of sublimable dyes for Y (yellow) are Kayace Yellow AG, Kayak Yellow TDN (manufactured by Nippon Kayaku Co., Ltd.), PTY 52, Dianix Yellow 5R-E, Dianix Yellow F3G-E, and Dianix Brilliant YG )), Plast Yellow 8040, DY108 (manufactured by Arimoto Chemical Co., Ltd.), Sumikaron Yellow EFG, Sumikaron Yellow E-4GL (manufactured by Sumitomo Chemical Co., Ltd.), FORON Brilliant YellowS6GLPI (manufactured by Sand), and the like.

  Examples of sublimable dyes for M (magenta) include, for example, Kayace Red 026, Kayet Red 130, Kayet Red B (manufactured by Nippon Kayaku Co., Ltd.), Oil Red DR-99, Oil Red DK-99 (manufactured by Arimoto Chemical Co., Ltd.) ), Diacelliton Pink B (manufactured by Mitsubishi Kasei Co., Ltd.), Srmikaron Red E-FBL (manufactured by Sumitomo Chemical Co., Ltd.), LateylRedB (manufactured by Du Pont), Sudan Red7B (manufactured by BASF), Resolin Red FB, CeresRed7 Examples include Bayer).

Next, it is preferable that the transfer paper is appropriately impregnated with sublimable dye ink. That is, if the dye ink enters the paper too deeply from the surface of the transfer paper, it tends to be difficult to sublimate at the stage of thermal transfer, and conversely, if the dye fine particles are not properly impregnated in the paper, ink bleeding occurs. . As the transfer paper, a paper made of cellulose pulp and subjected to appropriate waterproofing is used.
The transfer paper may be a roll or a sheet. In the case of a sheet-like transfer paper, it can be appropriately selected according to the size of the transfer image. Further, instead of the transfer paper, a fabric, nonwoven fabric or film having an appropriate impregnation property with sublimable dye ink may be used as the transfer body.

  Although details will be described later, the transfer paper in a state where the sublimation dye is impregnated with the sublimation dye pattern based on the digital image as described above is in close contact with the fastener in a state where the dentition row is fitted on the transfer table. In order to carry out thermal transfer in that state, it is placed in a pressurized and high temperature atmosphere. As a result, the sublimation dye held on the transfer paper sublimates to the base fabric portion of the fastener, which is the transfer object, and dyes the base fabric portion, whereby a digital image is drawn on the base fabric portion. become.

  In the present embodiment, the original image may be an analog image as well as the above digital image. Examples of analog images include photographic film images and posters, and these may be black and white or color.

  When the original image is an analog image, the image reading apparatus 101 converts an optical image obtained by an imaging unit including an optical element into a digital signal, performs predetermined signal processing, converts the image into digital image data, and outputs the digital image data. . Examples of the image reading apparatus 101 include a film scanner, an image scanner, a copier, or a complex machine of these.

  As an original image, in addition to the above-mentioned ones, a digital image received through a communication network can be used. It is possible to receive a digital image data transmitted using a communication network such as an electric communication line or an optical fiber communication, and manufacture a belt-like object in which an original image is transferred to an object to be transferred by a manufacturing method similar to the above. Examples of the transmission medium include a computer and a mobile phone.

In FIG. 3, the color pattern drawn on the transfer paper 30 (the color pattern of the sublimation dye pattern formed based on the digital image) is transferred to the base fabric portion 11, thereby forming the color pattern on the fastener 10. 2 shows an example of the configuration of a color pattern transfer device for this purpose.
As shown in FIG. 3, the color pattern transfer device 200 is attached and fixed to a pair of heat and pressure rollers 201 and 204 arranged in parallel in the vertical direction and outer peripheral surfaces of the heat and pressure rollers 201 and 204. The pair of transfer tables 203 and 206, the rotation shaft 201a for rotating the heat and pressure roller 201 to which the transfer table 203 is attached and fixed, and the rotation to similarly rotate the heat and pressure roller 204 to which the transfer table 206 is fixed and attached. It is comprised from the axis | shaft 204a. Further, in this configuration, a heater 202 serving as a heat source for heating the heat and pressure roller 201 is provided in the heat and pressure roller 201. Similarly, in the heat and pressure roller 204, A heater 205 serving as a heat source for heating the heat and pressure roller 204 is provided.
The heaters 202 and 205 are provided inside the heat and pressure rollers 201 and 204. However, the present invention is not limited to this. For example, the heat and pressure rollers 201 and 204 are heated from the outside. Anyway.

  In addition, in order to give stability to the heat generated by the heaters 202 and 205, oil may be injected inside the heat and pressure rollers 201 and 204. The rotating shafts 201a and 204a are configured to rotate in synchronization with each other. In this case, when the rotating shaft 201a rotates clockwise, the rotating shaft 204a rotates counterclockwise. .

  In FIG. 3, only one row of transfer tables 203 and 206 is attached to the heat and pressure rollers 201 and 204, respectively, but a plurality of rows may be attached. Further, since the size of the fastener tooth may vary depending on the product to be attached, a plurality of transfer tables for the tooth row corresponding to such a size may be prepared and appropriately replaced.

FIG. 4 is a perspective view showing a part of the transfer tables 203 and 206 shown in FIG.
Since the transfer table 203 and the transfer table 206 have the same structure, only the transfer table 203 will be described, and description of the transfer table 206 will be omitted.

  As shown in FIG. 4, the transfer table 203 has a recess 203a formed in the longitudinal direction. In the recess 203a, a plurality of protrusions projecting in a direction intersecting with the longitudinal direction of the recess 203a have a width substantially the same as or slightly narrower than the clearance width of each service tooth of the service tooth row 13 in the fastener 10. The protrusions 203b are arranged in the longitudinal direction of the recess 203a. In addition, the protrusions 203b are provided so as to face each other in the recess 203a and to be staggered.

Further, depending on the material of the dentition 13 of the fastener 10, the surfaces of the recess 203a and the protrusion 203b may be covered with a material such as sheet-like carbon graphite or silicon rubber.
For example, when the dentition 13 is made of resin, the surfaces of the recesses 203a and the projections 203b are covered with carbon graphite or silicon carbon graphite, and the surfaces of the recesses 206a and the projections 206b are covered with high heat transfer silicone rubber.
Further, when the dentition 13 is made of metal, the surfaces of the recess 203a and the projection 203b and the recess 206a and the projection 206b are covered with silicon carbon graphite.
Since these materials have flexibility, they reduce wear when the protrusions 203b, 206b and the dental dentition 13 come into contact with each other, and at the same time have high thermal conductivity. Therefore, the recesses 203a, 206a and the protrusions 203b, Even if it is pressure-bonded to the surface of 206b, heat conduction is not hindered.

  FIG. 5 shows a state in which the color pattern is transferred to the base cloth portion 11 of the fastener 10 by the color pattern transfer apparatus provided with the heat and pressure roller provided with the transfer table shown in FIG. In the case of this example, an upper stopper 14 and a lower stopper 15 are attached to the fastener 10, and the dentition row 13 is engaged.

  As shown in FIG. 5, when a color pattern is transferred to the base cloth portion 11 of the fastener 10 by the color pattern transfer device of this embodiment, first, the transfer paper 30 is brought into close contact with both surfaces of the fastener 10, and the fastener 10 in that state is placed. In a state where the transfer paper 30 is sandwiched between the color pattern transfer devices 200, the transfer paper 30 is fed from, for example, the right side to the left side in FIG. At this time, on the transfer tables 203 and 206, the dentition 13 of the fastener 10 is fitted into the recesses 203 a and 206 a, so that the fastener 10 and the transfer sheet can be transferred even if the heat and pressure rollers 201 and 204 rotate. The close contact state with 30 is maintained.

  6 schematically shows a state immediately before the fastener 10 and the transfer paper 30 in close contact with each other are sandwiched between the transfer stands 203 and 206 of the heat and pressure rollers 201 and 204, and FIG. 7 shows the fastener 10 and the transfer paper. 30 schematically shows a state where 30 is sandwiched between the transfer bases 203 and 206 of the heat and pressure rollers 201 and 204 to perform heat and pressure.

  As shown in FIGS. 6 and 7, the transfer sheet 30 is still in the gap between the engagement teeth 13 of the engagement tooth row 13 of the fastener 10 before being sandwiched between the transfer platforms 203 and 206 of the heat and pressure rollers 201 and 204. Although not entering, when the transfer paper 30 is sandwiched between the transfer bases 203 and 206 of the heat and pressure rollers 201 and 204, the transfer paper 30 is formed between the recesses 203a and 206a of the transfer bases 203 and 206 and the protrusions 203b and 206b. At the same time as being sandwiched between them, it is pushed between the respective dentitions of the dentition 13 of the fastener 10 and comes into close contact with the base cloth portion 11 between the dentitions.

  When the heat pressing rollers 201 and 204 are sandwiched between the transfer bases 203 and 206, the transfer bases 203 and 206 are flat with respect to the base fabric portion 10 other than the place where the dentition 13 of the fastener 10 is provided. The transfer paper 30 is brought into close contact with the portions (portions other than the recesses 203a and 206a and the protrusions 203b and 206b).

  Then, as shown in FIG. 7, the fastener 10 and the transfer paper 30 are brought into close contact with each other by being sandwiched between the transfer stands 203 and 206 of the heat and pressure rollers 201 and 204, and a certain amount of pressure (transfer pressure) is applied. At this time, heat (transfer heat) from the heaters 202 and 205 of the heat and pressure rollers 201 and 204 is applied to the fastener 10 and the transfer sheet 30. Thereafter, the transfer paper 30 and the fastener 10 that are kept in close contact with each other are sent out to the near side in FIG. 5 by the rotation of the heat and pressure rollers 201 and 204.

Hereinafter, heating and pressurizing conditions and heating time conditions when transferring the color pattern of the transfer paper 30 to the base cloth portion 11 of the fastener 10 by applying transfer heat and transfer pressure to the transfer paper 30 and the fastener 10 will be described. .
The transfer temperature can be appropriately selected depending on the type of sublimation dye, but in the present embodiment, it is in the range of 130 ° C. to 250 ° C., and more preferably in the range of 160 ° C. to 200 ° C.

In this embodiment, the transfer time is typically 0.5 to 5 minutes, and more preferably 0.6 to 1 minute. The heating time varies depending on the thermal properties of the sublimable dye. Generally, when high fastness is required after transfer, a sublimable dye having a thermal property that requires a high heating temperature and a long heating time is used.
Transfer pressure is preferably 0.01~1.0kg heavy ^{/ cm 2 (0.098~9.8N / cm 2} ), 0.02~0.5kg heavy ^/ cm 2 ^{(0.19~4.9N /} cm ² ) is more preferable.

  Further, in the present embodiment, since the transfer bases 203 and 206 shown in FIG. 3 are provided, as shown in FIG. 8, the transfer paper 30 pushed between the service teeth of the service tooth row 13 of the fastener 10 and The first pressure Pb applied to the base cloth part 11 between the service teeth and the first pressure Pb applied to the base cloth part 11 and the transfer paper 30 other than the place where the service tooth row 13 of the fastener 10 is provided. The ratio (Pb / Pa) of 2 to the pressure Pa enables adjustment according to the type of the dentition 13 of the fastener 10.

  When heat and pressure are applied to both the transfer paper 30 and the fastener 10 under the above-described conditions, the sublimation dye ink adhering to the transfer paper 30 is vaporized, and at the same time, the fiber molecules forming the base fabric portion 11 are heated. Separation begins and vaporized sublimation dye ink penetrates between the molecules. That is, when the base fabric portion 11 is formed of polyester fibers having a melting point of 220 ° C. to 330 ° C. (pure polyester has a melting point of 265 ° C.), heating at the transfer temperature of this embodiment is performed. When it is touched, the core of the polyester fiber begins to melt and melt. Then, the sublimation dye vaporized from the transfer paper 30 penetrates into the fibers that have started to melt.

  Thereafter, when the heating is finished and the temperature is lowered, the separation of the fiber molecules of the base fabric portion 11 is settled, and the sublimation dye ink that has been vaporized and penetrated into the fiber molecules of the base fabric portion 11 Fixed within the fiber molecule. Thereby, the dyeing | staining of the base fabric part 11 of the fastener 10 is completed.

  As described above, according to the present embodiment, not only the dyeing penetration can be adjusted by the amount of heat applied to the fastener 10, but also the engagement teeth of the fastener 10 can be formed by the recesses 203a and 206a and the protrusions 203b and 206b of the transfer bases 203 and 206. The transfer paper 30 is pushed between the respective dentitions of the row 13 and the transfer paper 30 pushed between the respective dentitions is pressed so as to be in close contact with the base cloth portion 11, and to the inter-engagement portion and the other portions. Since the ratio of the pressurization of the dentition 13 can be adjusted, the color of the minute portion in the gap between the dentitions in the fastener in which the dentition 13 is fitted, that is, the base cloth portion 11 between the dentitions. The pattern can be accurately transferred.

  Further, according to the present embodiment, as shown in FIG. 9, when transferring a fine line pattern having a width M formed on the transfer paper 30 as the color pattern of the base cloth part 11 of the fastener 10, for example, The width M of the fine line 11 is a fine line that falls within an error range of ± 0.2 mm or less with respect to the width M of the fine line on the transfer paper 30. Further, this error range is the same for the thin line transferred to the base cloth portion 11 in the space between the service teeth of the service gear row 13 of the fastener 10. The value of this “error” is somewhat affected by the surface roughness of the base fabric portion 11. However, even if the surface roughness of the base fabric portion 11 is 0.2 mm or more, the error can be ± 0.2 mm or less. If the surface roughness is small, the error can be 0.15 mm or less.

  When the thin line on the transfer paper 30 is compared with the thin line transferred to the base cloth part 11, the thin line transferred about 0.05 mm on the average is thicker. When a thin line having a width of 0.2 mm is prepared in advance on the transfer paper 30, it was actually measured that the transferred thin line was transferred approximately 0.05 mm thick.

  In addition, according to the present embodiment, the transfer sheet 30 is applied to the base cloth portion 11 between the respective engaging teeth of the engaging tooth row 13 of the fastener 10 and the base cloth portion 11 other than the place where the engaging tooth row 13 is provided. The color density change rate at the edge (color changing part) of the color pattern formed by transferring the color pattern can be suppressed by fine-tuning parameters such as heating temperature and heating time. is there.

  Further, in the present embodiment, as shown in FIGS. 5 to 7, both sides of the base fabric portion 11 of the fastener 10, particularly, the base fabric portion 11 in each interdental portion of the service tooth row 13 of the fastener 10. In addition to being able to transfer the color pattern on both sides simultaneously (the color pattern on both sides may be the same or different), as described above, the degree of dye penetration can be adjusted by heating and pressing. Made possible. Therefore, for example, as shown in FIG. 10, the thickness of the base fabric portion 11 is “T”, and the depth of T / 2 from one surface side of the base fabric portion 11 is the first depth “ta”. Suppose that the depth of T / 2 from the other surface side is the second depth “tb”. According to the present embodiment, for example, the error “± β between the first penetration depth ta ± β due to staining from one surface side and the second penetration depth tb ± β due to staining from the other surface side. However, the predetermined error amount is 20% or less at most, and can be reduced to 90% or more and 10% or less.

  Therefore, according to the present embodiment, the color pattern formed on the one surface side of the base fabric portion 11 does not affect the color pattern on the other surface side, and for example, during sewing, the base fabric portion The color of 11 fabrics is no longer visible. The first depth ta and the second depth tb do not necessarily have to be half the thickness T of the base fabric portion 11, and the quality of the color pattern formed on the surface of the base fabric portion 11 The depth may be within a range that does not allow the fabric color of the base fabric portion 11 to be seen during sewing.

  As described above, according to the present embodiment, it is possible to easily dye by a single transfer step, and it is necessary to perform pre-processing and post-processing such as discoloration processing by using a sublimation dye ink. Therefore, it is possible to color and pattern at low cost with a small number of man-hours, and it is possible to manufacture a fastener in which a precise color pattern is formed on the base cloth portion between the fasteners. In addition, according to the present embodiment, since a translucent polyester fiber or the like is dyed and colored and patterned, a high quality finish is achieved.

Also, in the case of this embodiment, unlike normal printing and dyeing, the dye penetrates into the fibers themselves and does not enter the gaps between the fibers, so that the slider of the fastener does not impair the breathability and ventilation of the fibers. There will be no problems with the operation. For example, it is not necessary to create a plate for each color as in screen printing, and printing is performed with a commercially available ink jet printer, which is advantageous in terms of work and cost, and is advantageous and inexpensive.
In addition, when using fasteners made of polyester resin for the dentition and polyester fabric for the base fabric, high-quality fasteners that allow uniform expression of the dye, no color unevenness, and the ability to express designs with fine lines You will be able to get

  In the present embodiment, the transfer method using a roller has been described. However, the present invention is not limited to this, and for example, two flat plate-like shapes provided with concave and convex portions according to the shape of each service tooth of the service tooth row. It is possible to employ a method in which a base cloth portion and transfer paper are stacked on the transfer table, heat from a heat source is applied to these two flat transfer tables, and pressure is applied. The present invention can also be applied to manual or automatic thermocompression bonding machines. In the case of an automatic type, the transfer temperature, transfer time, and transfer pressure can be automatically set to appropriate ranges.
