Description

  The present invention relates to a flocked transfer sheet, a transfer method of the flocked transfer sheet, and a garment on which a pattern is transferred by the flocked transfer sheet.

  As is well known, when a pattern or letter (hereinafter referred to as “pattern”) is given to a clothing item (for example, a T-shirt) manufactured in a small number of lots, the pattern is applied to the clothing item by a screen printing method or the like. Since the direct printing method increases the manufacturing cost, a method of transferring a pattern with a transfer sheet is often used.

  As a transfer sheet for transferring a pattern to clothing, a binder transfer sheet that transfers a binder colored with a dye or pigment as a pattern is generally used. Since the texture is completely different from the texture of clothing and the texture of clothing is worse, instead of the binder transfer sheet, many flocking transfer sheets that transfer short fibers colored with dyes and pigments as patterns are adopted. The texture transferred by the flocking transfer sheet is very similar to the texture of clothing, and the texture of the clothing is maintained.

  By the way, in recent years, the tendency for consumers to select clothing items with an emphasis on individuality has become stronger, and in association with this, numerous unique patterns with higher decorativeness can be transferred by flocking transfer sheets. Development is underway.

  For example, as shown in FIG. 5, a base material 101, a temporary adhesive layer 102 laminated on the base material 101, a short fiber layer 104 formed by implanting a plurality of short fibers 103 in the temporary adhesive layer 102, and a short It consists of a binder layer 105 for bonding the upper ends of the respective short fibers 103 constituting the fiber layer 104, and an adhesive layer 106 laminated on the binder layer 105. The binder layer 105 contains fiber pieces 107 having a metallic luster. Transfer sheet 108 (hereinafter referred to as “conventional transfer sheet”).

Further, in Patent Document 1 described later, after applying a flocking adhesive to a sheet-like temporary flocking base material such as a metal plate, a metal foil, and a heat-resistant synthetic resin, flocking metal short fibers or inorganic short fibers is performed. Then, a transfer sheet is disclosed in which a temporary flocked base is formed, and then a to-be-grafted metal substrate having a planar shape or a three-dimensional shape and the tips of the flocked short fibers of the temporary flocked base are fixed via a brazing material. ing.
JP-A-8-303978

  However, in the conventional transfer sheet, when the pattern is transferred to the clothing product, the fiber pieces contained in the binder layer can be observed only through the short fiber layer, and the texture of the pattern can be seen. When the number of the short fibers constituting the short fiber layer is increased in order to approach the distance, there is a problem that almost no fiber pieces can be confirmed from the surface.

  Moreover, in the transfer sheet disclosed in Patent Document 1, since all the short fibers are composed of inorganic short fibers or metal short fibers such as carbon fibers, glass fibers or ceramic fibers, the pattern of the flocked transfer sheet has a pattern. There was a problem that the good surface texture, which is a feature, was lost.

  Therefore, the present invention aims to realize a flocked transfer sheet that can form a pattern having a higher decorative effect without damaging the texture of the garment when transferred to the garment. Therefore, as a result of repeating trial manufacture and experiment, as a result, a short fiber layer and a short fiber layer formed by implanting one end of a plurality of short fibers in the temporary adhesive layer, a temporary adhesive layer laminated on the base material, and the temporary adhesive layer. In the flocked transfer sheet provided with an adhesive layer laminated so as to bury the other end of each short fiber constituting, the short fiber constituting the short fiber layer contains short fibers having metallic luster, and the metal By forming glossy short fibers longer than other short fibers, it is possible to reliably bond short fibers with a metallic luster that have a smooth surface and easily fall off from the adhesive layer, without impairing the texture of clothing. Imitation of a more decorative transfer Obtained a finding should Katsumoku that can be formed is obtained by achieving the technical problems.

  The technical problem can be solved by the present invention as follows.

  That is, the flocked transfer sheet according to the present invention includes a base material, a temporary adhesive layer laminated on the base material, a short fiber layer in which one end portion of a plurality of short fibers is planted in the temporary adhesive layer, and the short fiber layer. A flocked transfer sheet provided with an adhesive layer laminated so as to bury the other end of each short fiber constituting the short fiber, and has a metallic luster among the plurality of short fibers constituting the short fiber layer Short fibers containing short fibers having a metallic luster are formed longer than other short fibers other than the short fibers having the metallic luster.

  Further, in the flocked transfer sheet according to the present invention, a part or all of the short fibers having a metallic luster among the short fibers in which one end portion is flocked to the temporary adhesive layer is inclined with respect to the other short fibers. The other end is buried in the adhesive layer.

  Moreover, the apparel according to the present invention is one in which short fibers are transferred by any one of the flocking transfer sheets.

  Furthermore, the method for producing a flocked transfer sheet according to the present invention includes a short fiber flocking step in which a short fiber layer is formed by flocking one end of a plurality of short fibers to a temporary adhesive layer laminated on a substrate, and a short fiber layer. Each of the short fibers is formed by laminating an adhesive on the short fiber layer in a state where the short fibers having a metallic luster formed longer than the other short fibers are inclined with respect to the other short fibers. And an adhesive laminating step of forming the adhesive layer by burying the other end of the fiber in the adhesive.

  According to the present invention, the short fiber layer formed by implanting a plurality of short fibers in the temporary adhesive layer is transferred to the adhesive layer laminated on the short fiber layer by utilizing the difference in adhesive force, and is transferred to the transfer object. In the flocked transfer sheet for transferring the short fiber layer, the short fibers constituting the short fiber layer are made to contain short fibers having metallic luster, and the short fibers having metallic luster are formed longer than the other short fibers. It is possible to reliably bond short fibers with a metallic luster that have a smooth surface and easily fall off from the adhesive layer after transfer to the adhesive layer, and have a higher decorative effect without impairing the texture of clothing. A pattern can be obtained.

  Also, by burying the other end of each short fiber in the adhesive layer in a state where the short fibers having metallic luster among the short fibers planted in the temporary adhesive layer are inclined with respect to the other short fibers, Since the short fibers having a metallic luster are inclined, the other end of the short fibers are buried in the adhesive layer over a wide area, making it difficult to come off the adhesive layer after transfer, and the pattern was visually observed after transfer. At this time, the metallic gloss surface of the short fiber is oriented in the viewing direction, the metallic gloss is emphasized, and the decoration effect is improved.

  Therefore, it can be said that the industrial applicability of the present invention is very high.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

Embodiment 1 FIG.

  FIG. 1 is a cross-sectional view showing a flocking transfer sheet according to the present embodiment. FIG. 2 is an explanatory view showing a transfer process of the flocked transfer sheet shown in FIG. FIG. 3 is a cross-sectional view showing a modification of the short fiber layer before the adhesive layer in the present embodiment is laminated. In these drawings, reference numeral 1 denotes a base material 2, a temporary adhesive layer 3 laminated on the base material 2, and a short fiber layer 6 formed by flocking the temporary adhesive layer 3 with one end portion 5 of a plurality of short fibers 4. And a flocked transfer sheet comprising an adhesive layer 8 for bonding the other end 7 of each short fiber 4 constituting the short fiber layer 6, and the short fiber 4 constituting the short fiber layer 6 has a metallic luster. Short fibers 9 are included.

  The base material 2 should just be durable with respect to the heating and pressurization at the time of transfer. For example, a film made of a synthetic resin such as polycarbonate, polyethylene terephthalate, or polybutylene terephthalate, or paper such as high-quality paper or Japanese paper may be used.

  The temporary adhesive layer 3 may be formed of a pressure-sensitive adhesive whose adhesive force during transfer is weaker than the adhesive force of the adhesive layer 8. Therefore, the adhesive may always be an adhesive whose adhesive strength is weaker than the adhesive strength of the adhesive layer 8, and the adhesive strength is stronger than the adhesive strength of the adhesive layer 8 before heating during transfer, and the adhesive strength after heating. May be a pressure-sensitive adhesive that becomes weaker than the adhesive strength of the adhesive layer 8. Specifically, a synthetic resin such as a polyurethane resin, an acrylic resin, a polyester resin, or an ethylene vinyl acetate resin may be used.

  Short fibers made of rayon, nylon, polyester, acrylic, etc. may be used for the other short fibers 10 other than the short fibers 9 having metallic luster constituting the short fiber layer 6. In addition, the length of the other short fiber 10 should just be 0.3-1.5 mm, More preferably, it is 0.5-1.5 mm, and 0.8-1.2 mm is the most suitable. If the length of the other short fibers 10 is shorter than 0.3 mm, the length of the other end 7 embedded in the adhesive layer 8 is shortened, so that it is easy to come off from the adhesive layer 8 after the transfer. If the length is longer than that, a portion where the short fibers 4 are not implanted over a wide range when the temporary bonding layer 3 is not successfully implanted is caused. Further, the thickness of the other short fibers 10 is preferably 1.5 to 2.0 denier.

  The short fibers 9 having a metallic luster constituting the short fiber layer 6 are narrowly formed by attaching a metal thin film on one side or both sides of a film made of a synthetic resin such as polyester, polyolefin, polyamide, polyvinyl chloride or the like. What is cut may be used. In addition, what is necessary is just to form a metal thin film with metals, such as Al, Ag, Sn, Cu, Cr, Bi, Ti, Fe, Ni, or these alloys. In addition, it can also form by apply | coating the coating material which has metallic luster on the surface of the said film.

  Moreover, the length of the short fiber 9 which has metallic luster is formed longer than the other short fiber 10, 0.5-2.0 mm is preferable, More preferably, it is 0.7-1.5 mm. If the length of the short fiber 9 having metallic luster is shorter than 0.5 mm, the surface of the short fiber 9 is smooth, and thus the short fiber 9 is easily removed from the adhesive layer 8, so that the length of the portion embedded in the adhesive layer 8 is long. If the length is shorter than 2.0 mm and the fiber is not well planted in the temporary adhesive layer 3, a part where the short fiber 4 is not planted over a wide area is generated. Become.

  The adhesive layer 8 may be formed of an adhesive whose adhesive force during transfer is stronger than that of the temporary adhesive layer 3. For example, if it is made of an adhesive that melts by heating and is cured by cooling, it is made of synthetic resin such as urethane resin, nylon resin, polyester resin, acrylic resin, polyamide resin, ethylene vinyl acetate resin, etc. Good.

  Next, the manufacturing process of the flocked transfer sheet 1 according to the present embodiment will be described.

  First, a temporary adhesive layer 3 is formed by laminating a pressure-sensitive adhesive on one surface of the substrate 2, and then, one end portion 5 of a plurality of short fibers 4 is planted on the temporary adhesive layer 3 to short fibers. Layer 6 is formed (short fiber flocking process). At this time, the short fibers 9 having a metallic luster cut long in the short fibers 4 are implanted in a state of being almost upright with respect to the temporary adhesive layer like the other short fibers 10 cut short ( In FIG. 1, the short fibers 9 having the fourth metallic luster from the left in FIG. 1 are planted in a state where they fall between the other short fibers 10 and are inclined with respect to the other short fibers 10 (in FIG. 1, A short fiber 9) having a metallic luster that is seventh from the left and third from the right. Next, an adhesive is laminated on the short fiber layer 6 so that the other end 7 of each short fiber 4 is buried, thereby forming an adhesive layer 8 corresponding to the shape after transfer. At this time, the short fibers 9 having metallic luster are cut longer than the other short fibers 10, and therefore, even if the short fibers 9 having metallic luster implanted in any of the above states are used, the other short fibers 10. In contrast, the other end portion 7 is buried in the adhesive layer 8 over a wide range (adhesive laminating step).

  As a method for flocking the short fibers 4 to the temporary adhesive layer 3, an electrostatic flocking device may be used, and either an up method or a down method may be used. Further, when the short fibers 4 are planted in the temporary adhesive layer 3, the short fibers 4 are implanted so that all the short fibers 4 constituting the short fiber layer 6 are embedded in the temporary adhesive layer 3 at one end portion 5 to the same depth. That's fine. Thereby, when laminating the adhesive layer 8 on the short fiber layer 6, the short fiber 9 having a metallic luster extends over the adhesive layer 8 over the other end portion 7 over a wider range than the other short fibers 10. It becomes an embedded state.

  Further, the pressure-sensitive adhesive and the adhesive may be laminated by coating, or may be laminated by printing.

  Moreover, before laminating the adhesive layer on the short fiber layer, the short fiber may be colored with a dye or a pigment.

  In addition, as shown in FIG. 3, other short fibers among the short fibers 9 having a metallic luster implanted in the temporary adhesive layer 3 so that the short fibers 9 having a metallic luster reflect light more after transfer. Similarly, between the other short fibers 10 so that the one that is in an upright state (the short fiber having the fourth metallic luster from the left in FIG. 1) is inclined with respect to the other short fibers 10. The adhesive layer 8 may be laminated after the operation of tilting it down.

  At this time, the other short fibers 10 constituting the short fiber layer 6 are closely close enough to sandwich the short fibers 9 having a metallic luster in an inclined state between the other adjacent short fibers 10. In other words, the other adjacent short fibers 10 are densely arranged so as to be closer than the width of the short fibers 9 having metallic luster, so that the metallic luster that falls between the other short fibers 10 is reduced. The short fiber 9 is held in a state of being sandwiched by other short fibers 10, and the short fiber 9 having metallic luster is prevented from rising from a state inclined with respect to the other short fibers 10 to an upright state by a restoring force. it can.

  Next, the transfer process of the flocked transfer sheet 1 according to the present embodiment will be described.

  First, as shown in FIG. 2A, the surface of the flocked transfer sheet 1 on which the adhesive layer 8 is laminated is brought into close contact with a predetermined position of the transferred object 11, and then the substrate 2 of the flocked transfer sheet 1. Heat and pressurize from the side using a crimping machine. At this time, the adhesive forming the adhesive layer 8 melted by heating enters deeply into the gaps between the respective short fibers 4 and becomes more entangled with the other end portion 7 of each short fiber 4. Next, as shown in FIG. 2B, after cooling and curing the adhesive forming the adhesive layer 8, the substrate 2 on which the temporary adhesive layer 3 is laminated is peeled off. At this time, since the adhesive layer 8 is cured by cooling, it is in a state of being bonded with an adhesive force stronger than the adhesive force between the short fibers 4 and the temporary adhesive layer 3, so that the short fibers 4 are peeled off from the temporary adhesive layer 3. And remains on the adhesive layer 8 side. As a result, as shown in FIG. 2C, the pattern made of the short fibers 4 is transferred to the transfer target 11.

  The short fiber 4 that forms the transferred pattern is formed of a short fiber 9 having a metallic luster that is cut longer than the other short fibers 10 that are cut short. It is in a state embedded in. Moreover, the short fiber 9 having a metallic luster planted in the adhesive layer 8 in an inclined state with respect to the other short fibers 10 has a metallic luster surface facing the plane side, and is reflected by light reflection when viewed from the plane. A high decorative effect can be obtained.
