Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an embroidery sublimation transfer method and apparatus suitable for coloring and dyeing an embroidery pattern sewn onto an embroidery cloth or the like.

In general, an embroidery pattern is realized by sewing embroidery threads of multiple colors onto an embroidery cloth according to embroidery data. However, such an embroidery work requires a color changing work for exchanging threads of a plurality of colors, and workability and productivity cannot always be sufficiently improved. Therefore, after embroidering with a single color (white) embroidery thread, the surface side of the embroidery pattern is dyed with multiple colors using sublimation transfer technology. A sublimation transfer technique for embroidery has been proposed that enables easy formation (see, for example, Patent Documents 1 and 2).

The technique of sublimation transfer is generally known as a method of dyeing a pattern on a fabric (without embroidery), but it also applies sublimation transfer to color the embroidery pattern sewn on the fabric. be. In this case, for example, after plain embroidery is performed on the fabric using polyester white thread (one-color upper thread), the plain embroidery pattern is dyed by sublimation transfer. Therefore, for example, even when embroidering a complex pattern or gradation, it is not necessary to change the color during the embroidery work, and workability and productivity can be improved.

BEST MODE FOR CARRYING OUT THE INVENTION An embroidery sublimation transfer method and an apparatus therefor according to embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

Here, FIGS. 1 to 6 show the first embodiment of the invention. In FIG. 1, an embroidery cloth 1 is a cloth to be embroidered. The embroidery pattern 2 is formed as a "T" mark shown in FIG. In this case, the embroidery pattern 2 is realized by stitching the needle thread 3 to the embroidery cloth 1 so as to intertwine it with the bobbin thread (not shown). The embroidery pattern 2 of the "T" mark shown in FIG. 2 is merely a specific example, and the embroidery pattern 2 may of course be any pattern or pattern.

As shown in FIG. 2, the "T" pattern embroidery pattern 2 is plain embroidery made up of a combination pattern of a horizontally elongated portion 2A and a vertically elongated portion 2B. The laterally elongated portion 2A is formed as a stitch extending in the Y-axis direction for the needle thread 3 . The lengthwise portion 2B is formed as a stitch extending in the X-axis direction for the needle thread 3 . As for the stitches of the embroidery pattern 2, arbitrary stitches such as satin stitches can be selected to form the stitches.

The needle thread 3 is formed using, for example, white polyester thread (one-color thread). On the front side of the embroidery pattern 2 (needle thread 3 made of polyester), a pattern is dyed with a transfer pattern 5 as described later. Therefore, the embroidery pattern 2 shown in FIG.

As shown in FIG. 4, the transfer paper 4 is formed using a thin sheet-like paper material such as sublimation printing paper. On the surface of the transfer paper 4, for example, a "T"-shaped transfer pattern 5 is printed in advance with sublimation ink containing a sublimation dye as a dye. The transferred pattern 5 is a "T" pattern, which is a combination pattern of the horizontally elongated portion 5A and the vertically elongated portion 5B corresponding to the shape of the embroidery pattern 2. As shown in FIG. The transfer pattern 5 is not limited to the "T" pattern shown in FIG.

For example, in the case of the "T"-shaped transfer pattern 5, as one example, the horizontally elongated portion 5A is dyed with blue sublimation ink, and the vertically elongated portion 5B is dyed with, for example, yellow sublimation ink. Note that the oblong portion 5A is not limited to blue, and may be dyed with red, green, or other sublimation inks, or may be dyed with a plurality of colors of sublimation inks. The vertically elongated portion 5B is not limited to yellow, and may be dyed with red, green, or blue sublimation ink, for example, or may be dyed with a plurality of colors of sublimation ink. On the back surface of the transfer paper 4 (that is, the side on which the transfer pattern 5 is not printed), a protective film for preventing permeation is applied so that part of the transfer pattern 5 (sublimation ink) does not ooze out during sublimation transfer, which will be described later. (not shown) and the like are preferably formed in advance.

As shown in FIG. 5, the cushion material 6 is formed in a sheet shape from a material softer than the needle thread 3, such as heat-resistant sponge or felt fabric. The cushion material 6 is formed as a flat sheet equal to or larger than the transfer paper 4 so as to completely cover the back side of the transfer paper 4 from the outside (for example, the upper side).

The cushion material 6 is a member that is interposed (inserted) between the transfer paper 4 and the clamping plate 13 during sublimation transfer, which will be described later, and buffers (relieves) the direct application of the pressure from the press 7 to the transfer paper 4 . be. For this reason, the cushion material 6 is formed to have a thickness greater than that of the embroidered cloth 1, as shown in FIG. Many hollow air layers are formed inside the cushion material 6, and these air layers have high heat insulating performance.

As shown in FIG. 6, the press machine 7 has a pedestal 8 for supporting the embroidered cloth 1 on which, for example, the embroidery pattern 2 is sewn from below, and a pedestal 8 standing upward from the rear end side of the pedestal 8. A column 9, a movable body 10 which is provided on the column 9 and moves up and down, and an actuator 11 which is suspended from the column 9 in order to move the movable body 10 up and down. is composed of A movable body 10 of the press machine 7 is arranged at a position facing the pedestal 8 in the upper and lower directions. The actuator 11 is composed of a hydraulic cylinder or an electric linear actuator, and is driven in the direction of the arrow (upward, downward) shown in FIG. .

A pedestal 8 of the press 7 is provided with a lower clamping plate 12 . The sandwiching plate 12 is provided with a heater 12A that generates heat when energized from the outside. The heater 12A heats the clamping plate 12 to a temperature required for sublimation transfer (for example, about 180 to 200.degree. C.). The pedestal 8 is made of a material that suppresses heat conduction, such as ceramics, and has a function of suppressing heat from the holding plate 12 (heater 12A) from radiating to the outside through the pedestal 8 .

If the pedestal 8 is made of a metal material, a heat-insulating sheet (not shown) may be provided between the pedestal 8 and the clamping plate 12 to suppress heat conduction. Moreover, the pedestal 8 and the clamping plate 12 may be integrated, and in this case, the pedestal 8 constitutes a part of the clamping plate 12 .

A movable body 10 of the press machine 7 is provided with an upper clamping plate 13 . The clamping plate 13 moves toward or away from the pedestal 8 (lower clamping plate 12) together with the movable body 10 in the direction of the arrow (upward or downward) shown in FIG. 7 is driven by an actuator 11 . The movable body 10 and the clamping plate 13 may be integrated, and in this case, the movable body 10 constitutes a part of the clamping plate 13 . The lower clamping plate 12 and the upper clamping plate 13 clamp the embroidery cloth 1 from both the front side and the back side so that the transfer pattern 5 of the transfer paper 4 is pressed against the front side of the embroidery pattern 2 of the embroidery cloth 1. It consists of two clamping plates.

At this time, the cushion material 6 is interposed between the transfer paper 4 and the front (upper) holding plate 13 of the two holding plates. The movable body 10 of the press machine 7 presses the two clamping plates 12 and 13 toward each other between the pedestal 8 and the transfer pattern 5 of the transfer paper 4 onto the embroidery pattern 2 of the embroidery cloth 1 by this pressing force. press against. In this way, the presser 7 applies pressure to the transfer paper 4 via the cushion material 6 from the front side of the embroidery pattern 2 of the embroidery cloth 1 (material). At this time, the heater 12A of the clamping plate 12 heats the back side of the embroidery cloth 1 for sublimation transfer. Heating by the heater 12A is preferably performed at a temperature of, for example, about 180 to 200° C. for about 1 to 5 minutes.

The transfer pattern 5 preliminarily printed on the transfer paper 4 is pressurized by the press 7 and heated by the heater 12A to evaporate the dye of the sublimation ink and chemically bond the needle thread 3 (polyester white thread) of the plain embroidery. react. As a result, the front side of the embroidery pattern 2 (needle thread 3 made of polyester) is dyed with the transfer pattern 5 . The embroidery pattern 2 in FIG. 1 has a dyeing pattern 15 transferred from the transfer pattern 5 on the front side thereof.

Note that the two clamping plates 12 and 13 may be provided by reversing the positional relationship shown in FIG. In this case, the transfer paper 4 is placed on the lower clamping plate with the cushion material 6 interposed therebetween, the embroidery cloth 1 is placed above the transfer paper 4, and the embroidery pattern 2 faces the transfer pattern 5 of the transfer paper 4. may be arranged to At this time, the back side (upper side) of the embroidery cloth 1 may be heated for sublimation transfer from the upper clamping plate side.

The sublimation transfer apparatus for embroidery according to the first embodiment has the configuration described above. Next, a method of sublimation transfer to the embroidery pattern 2 using the apparatus will be described.

The press machine 7 shown in FIG. 6 moves the movable body 10 upward by means of the actuator 11, and in this state, the embroidery cloth 1 (with the embroidery pattern 2 already sewn on it) is placed on the holding plate 12 on the lower side. Deploy. In addition, the transfer paper 4 shown in FIG. That is, the transfer paper 4 is arranged so that the “T”-shaped transfer pattern 5 printed on the surface of the transfer paper 4 faces the “T”-shaped embroidery pattern 2 formed on the embroidery cloth 1 above and below. are superimposed on the upper side of the embroidered cloth 1.

In this state, a cushioning material 6 made of a soft material is arranged so as to cover the back side of the transfer paper 4 (that is, the side on which the transfer pattern 5 is not printed) from above. As a result, the cushion material 6 is interposed (inserted) between the transfer paper 4 and the clamping plate 13 before sublimation transfer is started. On the other hand, the lower clamping plate 12 provided on the pedestal 8 of the press machine 7 is provided with a heater 12A that generates heat when energized from the outside. For example, it is heated to about 180 to 200°C.

Next, in this state, the movable body 10 of the press machine 7 is pushed downward by the actuator 11, and the pattern 5 of the transfer paper 4 is transferred to the embroidery cloth 1 between the lower clamping plate 12 and the upper clamping plate 13. The fabric of the embroidery pattern 2 (embroidery cloth 1) is sandwiched from both the front side and the back side so as to be pressed against the front side of the embroidery pattern 2. At this time, a cushioning material 6 made of a soft material is interposed between the holding plate 13 on the upper side (front side) and the transfer paper 4 so as to prevent the embroidery pattern 2 from collapsing.

The presser 7 presses the transfer paper 4 through the cushion material 6 from the front side of the embroidery pattern 2 of the embroidery cloth 1 (fabric). At this time, the back side of the embroidery cloth 1 is heated by the heater 12A of the holding plate 12 for sublimation transfer. Heating by the heater 12A is preferably performed at a temperature of, for example, about 180 to 200° C. for about 1 to 5 minutes.

As a result, the transfer pattern 5 preliminarily printed on the transfer paper 4 is pressed by the press machine 7 and heated by the heater 12A to evaporate the dye of the sublimation ink, and the upper thread 3 (polyester white thread) of plain embroidery is formed. ). As a result, the front side of the embroidery pattern 2 (polyester needle thread 3) is dyed with the transfer pattern 5, and as shown in FIG. A dyeing pattern 15 is transferred.

By the way, if the cushioning material 6 is not interposed between the clamping plate 13 and the transfer paper 4, when the embroidery pattern 2 is dyed by sublimation transfer, the embroidery will be embroidered as the pressure and heat are applied by the press machine 7. The pattern 2 may be crushed in the direction indicated by the arrow in FIG. 3, and there is a risk that the original softness and three-dimensionality of the embroidery will be lost.

Therefore, in the first embodiment, the cushion material 6 is interposed between the clamping plate 13 and the transfer paper 4, and the transfer pattern 5 of the transfer paper 4 is applied to the embroidery cloth 1 by using the press machine 7. When pressed against the front side of the transfer paper 4, the transfer paper 4 is pressed through a cushion material 6 made of a soft material.

Therefore, during the sublimation transfer by the press machine 7, the pressure force (indicated by the arrow in FIG. 6) from the upper clamping plate 13 directly acting on the transfer paper 4 can be buffered (relieved) by the cushion material 6. . As a result, it is possible to prevent the embroidery pattern 2 (i.e., the stitches of the upper thread 3) from being crushed due to the pressure and heat applied by the press machine 7, so that the original softness and three-dimensionality of the embroidery can be maintained even after sublimation transfer. be able to.

Further, in the present embodiment, the transfer pattern 5 pre-printed on the transfer paper 4 is pressed by the press machine 7 and heated by the heater 12A so that the needle thread 3 (polyester white thread) of the plain embroidery is applied to the front side of the needle thread 3 (polyester white thread). thermal transfer to Therefore, even if the transfer pattern 5 is a complicated pattern, the transfer pattern 5 is reproduced on the embroidery pattern 2 by transferring the dyeing pattern 15 to the surface side of the plain embroidery pattern 2 sewn on the embroidery cloth 1.例文帳に追加be able to.

Moreover, the plain embroidery pattern 2 is formed by a white polyester thread (needle thread 3). For this reason, even if the transfer pattern 5 is printed on the plain embroidery pattern 2, the transfer pattern 5 is not affected by the plain embroidery pattern 2 from the color surface, etc. 5 can be faithfully reproduced on the surface side of the plain embroidery pattern 2. - 特許庁

Furthermore, in the first embodiment, the transfer paper 4 is heated from the back side of the embroidered cloth 1, that is, by the heater 12A of the holding plate 12, for sublimation transfer. Therefore, even if the cushion material 6 having heat insulating properties is interposed between the transfer paper 4 and the clamping plate 13, the heat generated by the heater 12A can be transferred to the transfer paper 4 from the lower side of the embroidery cloth 1. It is possible to prevent the heat transfer from being interrupted by the cushion material 6 and to perform efficient heat transfer.

Next, FIG. 7 shows a second embodiment of the present invention. In this embodiment, the same reference numerals are assigned to the same components as in the first embodiment, and the description thereof is omitted. and However, the feature of the second embodiment is that the embroidery pattern 2 is sewn on the embroidery cloth 1 with the cover paper 21 overlaid thereon, and part of the ink by sublimation transfer is transferred to the embroidery cloth 1 other than the embroidery pattern 2. It is in that it was set as the structure which prevents it adhering to.

The cover paper 21 is a masking sheet made of thin paper such as tracing paper, glassine paper, or oil paper. Alternatively, the cover paper 21 may be made of a masking sheet made of a polymeric film such as silicone, polyester, or polypropylene. The cover paper 21 is used, for example, to prevent part of the sublimation ink printed on the transfer paper 4 from protruding from the embroidery pattern 2 and adhering to the front side of the embroidery cloth 1 .

As shown in FIG. 7, the embroidered cloth 1 on which the embroidery pattern 2 is sewn while the cover paper 21 is superimposed is placed above the holding plate 12 on the lower side. The paper 4 is placed upside down. In this state, a cushioning material 6 made of a soft material is arranged so as to cover the back side of the transfer paper 4 (that is, the side on which the transfer pattern 5 is not printed) from above.

Next, in this state, the movable body 10 of the press machine 7 is pushed downward by the actuator 11, and the pattern 5 of the transfer paper 4 is transferred to the embroidery cloth 1 between the lower clamping plate 12 and the upper clamping plate 13. The fabric of the embroidery pattern 2 (embroidery cloth 1) is sandwiched from both the front side and the back side so as to be pressed against the front side of the embroidery pattern 2. At this time, the lower clamping plate 12 provided on the pedestal 8 of the press 7 is heated by the heater 12A to a temperature required for sublimation transfer (for example, about 180 to 200.degree. C.).

Thus, in the second embodiment configured as described above, the presser 7 applies pressure to the transfer paper 4 via the cushion material 6 from the front side of the embroidery pattern 2 of the embroidery cloth 1 (material). Heating for sublimation transfer is performed from the back side of the embroidered cloth 1 by the heater 12A of the clamping plate 12. As shown in FIG. The transfer pattern 5 preliminarily printed on the transfer paper 4 can be thermally transferred to the surface side of the needle thread 3 (polyester white thread) of plain embroidery by applying pressure by the press machine 7 and heating by the heater 12A. By using 6, it is possible to prevent the embroidery pattern 2 (that is, the stitches of the needle thread 3) from being crushed.

In particular, in the second embodiment, the embroidery pattern 2 is sewn on the embroidery cloth 1 with the cover paper 21 overlaid thereon. The cover paper 21 can prevent the embroidered cloth 1 from adhering to the 1 side, and can prevent stains or the like due to thermal transfer from remaining on the surface side of the embroidered cloth 1.例文帳に追加Moreover, the cover paper 21 can be easily removed from the surface side of the embroidered cloth 1 by using the seams (perforations) of the embroidery pattern 2 after the sublimation transfer is performed by the press machine 7 .

Furthermore, the cover paper 21 superimposed on the embroidery cloth 1 is interposed between the heater 12A on the holding plate 12 side and the transfer paper 4. As shown in FIG. Therefore, the cover paper 21 can prevent high heat from the heater 12A from being transferred to the cushioning material 6, thereby preventing thermal deterioration of the cushioning material 6 and increasing durability and life.

In each of the above-described embodiments, the press machine 7 having the form in which the pedestal 8 is arranged on the lower side and the movable body 10 is arranged on the upper side has been described as an example. However, the present invention is not limited to this. For example, a press machine having a configuration in which the movable body is arranged below the fabric (for example, the embroidered fabric 1 on which the embroidery pattern 2 is sewn) and the base is arranged above the fabric. may be In this case, the movable body is driven upward by the actuator so as to sandwich the fabric between the upper sandwiching plate and the base via the lower sandwiching plate, the cushioning material and the transfer paper, for example.

In addition, the movable body of the press is not necessarily configured to move up and down. For example, the fabric is sandwiched between the movable body and the pedestal from the left and right directions or from the front and rear directions to perform sublimation transfer. It may be a press machine configured to perform. Further, the sublimation transfer press may be of a type in which the end of the movable body is hinged to the end of the pedestal so that the movable body can be opened and closed by tilting obliquely from the pedestal. On the other hand, the actuator of the press machine is not limited to a hydraulic cylinder or an electric linear actuator, and may be configured to drive a movable body by manual operation, for example.

Further, in each of the above-described embodiments, the heater 12A is provided on the lower holding plate 12, and the case where the heating for the sublimation transfer is performed from the lower side of the embroidered cloth 1 has been described as an example. However, the present invention is not limited to this. For example, the heating for sublimation transfer may be performed from both the lower side and the upper side of the embroidered cloth 1 . When heating for sublimation transfer is performed through the upper clamping plate 13, there is a possibility that the cushioning material 6 arranged between the transfer paper 4 and the clamping plate 13 is thermally deteriorated. However, if the cushioning material 6 is replaced early, the heating for the sublimation transfer may be performed through the holding plate 13 on the upper side.

Furthermore, in each of the above-described embodiments, the case where the lower holding plate 12 is provided with the heater 12A has been described as an example. However, the present invention is not limited to this. For example, a heater for heating may be provided outside the clamping plate 12, and the heat from the heater may be transmitted to the embroidery cloth and the transfer paper via the clamping plate.
