Description

  The present invention relates to a convex mark member that has a soft feeling as a whole and has a little uncomfortable feeling when attached to a flexible adherend, and a method for manufacturing the same.

  In clothing, bags, and sporting goods, a sheet-like mark member different from the main body material may be attached to enhance decorative effects, safety, added value, etc. Examples include team name, shoulder patch, and number. The main purpose of the conventional mark member is a decorative effect. For example, a relatively thick felt piece, woven piece, knitted piece, or resin sheet printed in multiple colors is used. These members are limited to processing methods and materials, and are often in the form of simple sheets. The degree of freedom in design is low, and high designability is difficult to express.

  In order to three-dimensionally form letters and marks, Utility Model Registration No. 3079054 uses a reflective film made of resin foam sticker with a foam of vinyl foam on the surface of soft vinyl and coated with fine glass beads. The whole is put into a convex or concave mold, and the whole is crimped by applying a high frequency in a pressurized state from the surface side. JP, 2010-222716, A exists as another example of a solid mark member, a surface layer and a back layer are pasted together, a dark pattern is included in the surface layer, and at least a part is cut out to give a three-dimensional effect. . A three-dimensional patch is disclosed in Utility Model Registration No. 3152523, and the decorative cloth on the surface has an outer periphery larger than the outer edge of the shape of the inner sheet, and is integrated with the cloth by sewing from the decorative cloth. The periphery of the decorative cloth is trimmed with embroidery or edge thread.

Utility Model Registration No. 3079054 JP 2010-222716 A Utility Model Registration No. 3152523

  The reflective sticker disclosed in Utility Model Registration No. 3079054 is harder to sew on clothing such as soft vinyl and foamed vinyl than the material of clothing, and even if it is pasted A strong sense of discomfort. When a mark has a cut-out portion as in JP 2010-222716, the surface layer is easily peeled off from the cut-out portion during use, and the back layer is a glossy woven fabric having a back layer, which increases the manufacturing cost. In addition, the decorative fabric used in Utility Model Registration No. 3152523 has a resin film laminated on the back side of the woven fabric or knitted fabric. Therefore, depending on the adherend, that is, the material of the fabric, distortion may occur during sewing, such as a hat or a T-shirt. In products that directly touch the skin, there is a concern that surrounding embroidery or edging may come into contact with the skin and cause skin disorders.

  The present invention has been proposed in order to improve the above-mentioned problems relating to the conventional three-dimensional mark, and it is an object of the present invention to provide a convex mark member that has a three-dimensional effect with a soft feeling as a whole and has durability. Yes. Another object of the present invention is to provide a convex mark member that can be applied to other members as a product protective material and a shock absorber in addition to a flexible adherend such as clothing. Another object of the present invention is to increase the stability at the time of three-dimensional molding and the strength of the mark member itself by sandwiching a fiber fabric such as polyester sheeting between a surface layer sheet excellent in design and the like and an elastic core material. It is to provide a method for manufacturing a convex mark member.

  In the method for manufacturing a mark member according to the present invention, the mark material is dried by applying a hot melt resin to the lower side of the fiber fabric, and then thermally compressing the entire fiber fabric on the adhesive layer of the thermal transfer sheet. It is preferable to form a heat-sensitive adhesive layer. When the surface layer sheet is a thermal transfer sheet, the carrier film on the surface of the thermal transfer sheet is peeled off after temporary adhesion. Furthermore, in order to adhere to the adherend, it is preferable to form a heat-sensitive adhesive layer by thermocompression bonding of a heat-fusible film below the mark member.

  The convex mark member according to the present invention has a soft feeling as well as a rich three-dimensional effect, and can have both design and cushioning properties by appropriately selecting a surface layer sheet. The convex mark member of the present invention can be applied not only as a flexible adherend such as clothing but also as a product protective material or shock absorber in sports equipment and manual tools due to the combination of design and cushioning. is there. Further, in the convex mark member of the present invention, all of the surface layer sheet, the fiber fabric and the elastic core material are in close contact with each other in the periphery of the mark, so that they hardly peel off during use, and are resistant to washing and abrasion. It is excellent with respect to.

  As illustrated in FIG. 1, the convex mark member 1 according to the present invention is usually a flexible surface layer sheet 2, a reinforcing fiber fabric 3 bonded to the surface layer sheet, and a lower side of the fiber fabric. And a flexible elastic core material 5 adhered to the substrate. The mark member 1 shown in FIG. 1 is attached to an adherend 7 such as clothing via a heat-sensitive adhesive layer 6 formed on the lower surface, but instead of laminating the adhesive layer 6, simple pressure bonding with a pressure-sensitive adhesive layer is used. It is also possible to bond by elastic melting of the surface of the elastic core material 5, application of a heat-sensitive adhesive, interposition of a heat-fusible sheet, or the like.

  The surface layer sheet 2 is desirably flexible using a material such as polyurethane. If desired, the surface layer sheet 2 may be appropriately printed on the surface, or a fine concavo-convex pattern or a retroreflective pattern may be formed on a part or the whole of the surface to enhance the design. The surface layer sheet 2 generally has an adhesive layer 22 (see FIG. 2) on its lower surface, and when such an adhesive layer is not present in the surface layer sheet, It is necessary that the fiber fabric 3 can be closely adhered by applying an adhesive or the like.

  The surface layer sheet 2 is generally a flexible resin sheet. For example, a thermal transfer sheet 8 (manufactured by Japan Polymer Co., Ltd.), a retroreflective sheet 10 (see FIG. 3), a color sheet, a phosphorescent sheet, and a fluorescence as shown in FIG. Sheets, low friction sheets, sublimation transfer fabrics (manufactured by Japan Polymerku), and the like can be listed. As the surface layer sheet 2, a commercially available retroreflective sheet (for example, manufactured by Unitika Sparklite), a retroreflective cloth or a fluorescent reflective cloth laminated with a glass sphere exposed type or a transparent surface resin layer may be used, and the back surface is cross. If so, it becomes a substitute for the fiber fabric 3.

  When the surface layer sheet 2 is the thermal transfer sheet 8 or the retroreflective sheet 10, the thermal transfer sheet has a multilayer structure as illustrated in FIG. 2, for example, a protective layer (not shown), a design layer 16, a backup layer 18, an intermediate layer The layer 20 and the adhesive layer 22 are formed, and these layers may be formed by screen printing. The carrier film 14 or the base film 42 is usually present on the surface of the sheets 8 and 10, and the film is generally made of a polyester film or the like. A smooth release layer is formed on the surface of this type of film, and it is generally desirable to have a matte finish or gloss finish and peel after temporary bonding.

 The reinforcing fiber fabric 3 has the same planar shape as the surface layer sheet 2, enhances the tear resistance of the flexible surface layer sheet 2 to prevent tearing during three-dimensional molding, and increases the mechanical strength of the mark member 1. Increase the washing resistance after attachment to the adherend 7. This fiber fabric can be omitted when the surface layer sheet 2 is highly stretchable and a specific preheating temperature and pressure / heating at the time of three-dimensional molding are set.

  The fiber fabric 3 is generally a relatively thick woven or knitted fabric such as polyester, nylon, or acrylic fiber. Preferably, the fiber fabric 3 is a polyester sheet having a relatively high elasticity (for example, a fine mold product) or an equivalent thereof, smooth knit, 2WAY tricot, and the like.

The fiber fabric 3 may be thermocompression bonded to the surface layer sheet 2 such as the thermal transfer sheet 8 through the adhesive layer 22 before temporary adhesion. At the time of this thermocompression bonding, the carrier film 14 of the thermal transfer sheet 8 is basically left without being peeled off after temporary adhesion for surface protection. This thermocompression bonding is preferably performed by heating and pressurizing at a temperature of 130 to 160 ° C. and a pressure of 0.5 to 1 kg / cm ² for 10 seconds to 20 seconds using a thermal transfer machine such as a transformer jumbo. The fiber fabric 3 is interposed in order to prevent the surface layer sheet 2 from tearing during three-dimensional molding and to improve the strength of the convex mark member 1.

  As shown in FIG. 4, the mark material 12 means a multilayer structure material in which a heat-sensitive adhesive layer 24 is provided on the back side of the fiber material 3 or the surface layer sheet 2, and is an intermediate material when the convex mark member 1 is manufactured. In the mark material 12, the fiber material 3 is usually interposed between the surface layer sheet 2 and the heat-sensitive adhesive layer 24. This fiber material can be omitted by substituting the fiber material if the fiber material is inserted in the surface layer sheet 2 in advance.

  As the mark material 12, a commercially available retroreflective fabric or decorative fabric having a heat-sensitive adhesive layer may be used as it is. When the elastic core material 5 is relatively thin, the fiber material 3 below the surface sheet 2 is used. May be omitted. The heat-sensitive adhesive layer 24 laminated on the lower surface of the mark material 12 is, for example, a heat-fusible resin after the surface layer sheet 2 and the fiber material 3 are bonded in order to join the elastic core material 5 such as urethane foam during temporary bonding. Is screen-printed on the lower surface of the fiber material 3, and the mesh of the screen plate is about 50 to 100 mesh. The heat-sensitive adhesive layer 24 can be laminated by interposing a heat-fusible film or spraying or applying an adhesive.

  The flexible elastic core material 5 has a thickness of 3 to 20 mm and has the same planar shape as the surface layer sheet 2. The elastic core material 5 is hard or soft foamed polyurethane, needle felt, contracted felt, nonwoven fabric, foamed polyethylene, or foamed EVA, and the type and thickness are selected according to the application. When the elastic core material 5 is polyurethane foam, the type is GL type (hard type and low cost), USW type (soft type), and the thickness is 3 mm, 5 mm, 7 mm, etc. The type and thickness of the material can be changed.

  In order to manufacture the convex mark member 1, the mark material 12 shown in FIG. 4 is first roughly cut together with the elastic core material 5 and the heat-fusible film 26 in accordance with the mark plane shape A (see FIG. 5). All three parties have the same planar shape. In this rough cutting, a simple planar shape such as a rectangular shape or a circular shape including the mark planar shape may be used. At this time, the heat-fusible film 26 usually has a melting point lower than the heating temperature during three-dimensional molding, and is generally integrated with the release paper. When the heat-fusible film 26 is not used, the heat-sensitive adhesive layer 6 does not exist on the back surface of the convex mark member 1. The convex mark member without the bottom surface adhesive layer is sewn to the adherend 7 by sewing, or after punching, is adhered to the adherend 7 by interposing a heat-fusible film or by spraying or applying an adhesive. do it.

As shown in FIG. 6, the mark material 12 and the elastic core material 5 are temporarily bonded by a flat press die 28. In the flat press die 28, the compression gap between the pressing die and the cradle at the time of temporary bonding substantially corresponds to the thickness of the elastic core material 5, and the interval is 3 to 20 mm. Avoid strong compression deformation. The press conditions for temporary bonding are preferably a pressure of ^{2 to} 6 kg / cm ² , a temperature of 100 ° C. to 150 ° C., and a pressing time of 10 to 20 seconds depending on the material of the surface layer sheet 2.

  If the carrier film 14 or the base film is adhered to the mark material 12 by the temporary bonding, the surface of the surface layer sheet 2 can be protected by peeling off after the temporary bonding. The carrier film 14 or the base film may be peeled off after the press heat is cooled to room temperature, depending on the material of the surface layer sheet 2. In the surface layer sheet 2 in which no protective film exists, a carrier film can be newly affixed before temporary bonding in order to protect the surface.

  The flat temporary adhesion mark material 30 is preferably preheated in a heating furnace (not shown) in order to prevent tearing of the surface layer sheet before three-dimensional molding. This preheating temperature and time are adjusted according to the material of the surface layer sheet 2, and generally the preheating temperature should be increased as the elastic core material 5 is thicker. Generally, the preheating temperature is 50 to 80 ° C., and the preheating time is 10 to 20 seconds. Preferably there is.

As shown in FIG. 7, the preheated temporary adhesion mark material 30 is placed in a reverse direction on a concave mold 34 of a press 32 and is three-dimensionally formed by a heating / pressing press to obtain a convex mark material 36. The concave mold 34 has a maximum depth of 8 mm or less, and the entire periphery thereof is usually positioned inside the entire periphery of the molded product. The press conditions for the three-dimensional molding are preferably a temperature of 150 ° C. to 250 ° C. and a pressure of ² to 6 kg / cm ² for 30 to 120 seconds.

A heat-sensitive adhesive layer 6 is laminated on the lower surface of the three-dimensionally formed convex mark member 1 as desired. At this time, the heat-fusible film 26 cut according to the shape of the mark plane melts at a temperature of 200 ° C. or higher at the time of three-dimensional molding. Integrate with 36. The integrated pressing conditions are preferably a temperature of 90 ° C. to 130 ° C. and a pressure of ² to 6 kg / cm ² for 5 seconds to 15 seconds.

  The obtained convex mark member 1 has a planar shape corresponding to decorative characters, figures, trademarks, etc., as shown in FIG. 5A, and has a protrusion 40 in which the surface layer sheet 2 partially protrudes upward, It is a general form to descend gently from the protruding central portion to the peripheral contact portion 38. In the convex mark member 1, the surface layer sheet 2, the fiber fabric 3, and the elastic core material 5 have a mutual adhesion portion 38 (FIG. 1) at least around the entire mark, and the adhesion portion has a width of 1 to 5 mm and a thickness, for example. Is preferably 0.3 to 1.0 mm. The convex mark member 1 has improved beauty and durability by, for example, the central portion 40 of the surface layer sheet 2 protruding in a band shape and having the mutual adhesion portion 38 around the entire mark.

  Next, the present invention will be described based on examples, but the present invention is not limited to the examples. In order to manufacture the thermal transfer sheet 8 shown in FIG. 2, a release agent such as a cellulose-based resin is used as a carrier film 14 with a 300-mesh screen plate on the entire surface of a matte or glossy polyester film having a thickness of 100 μm. Print 5 μm and dry. Next, a protective layer (not shown) and a design layer 16 are provided on the carrier film 14. For example, as the pattern layer 16, the black ink is made of polyurethane resin, polyester resin, isocyanate resin, and carbon black pigment. This two-component cross-linking paste is printed with a 225 mesh screen plate to form a black pattern layer 16 having a thickness of 4 to 8 μm.

  A white backup layer 18 and an intermediate layer 20 are laminated on the entire surface of the pattern layer 16 by screen printing, and these layers 18 and 20 also include polyurethane resin, polyester resin, polyamide resin, isocyanate resin, and the like. This two-component cross-linking paste is printed and dried by a 70-mesh screen plate to form a backup layer 18 and an intermediate layer 20 having a thickness of 15 to 20 μm. The adhesive layer 22 is enlarged by 0.2 mm from the entire surface of the pattern layer 16 and is formed by screen printing. The adhesive layer 22 is made of, for example, a polyurethane resin or a polyester resin, and when printed and dried using a screen plate of 100 to 70 mesh, the thickness of the adhesive layer 22 is 60 μm as a whole.

Next, in order to manufacture the mark material 12 (FIG. 4), the thermal transfer sheet 8 that is the surface layer sheet 2 is thermocompression bonded with a polyester sheet (product number: CR7500, fine mold product) that is the fiber fabric 3 for reinforcement. At the time of this thermocompression bonding, the carrier film 14 of the thermal transfer sheet 8 is left without being peeled after the transfer for surface protection. This thermocompression bonding is performed at a temperature of 130 to 160 ° C. and a pressure of 0.5 to 1 kg / cm ² for 10 to 20 seconds using a trans jumbo (trade name: JP-5040A) which is a thermal transfer machine. After the thermal transfer sheet 8 and the fiber fabric 3 are attached, the hot-melt resin is screen-printed on the surface of the reinforcing fabric using a screen mesh 70 mesh to form the heat-sensitive adhesive layer 24.

  The mark material 12 is roughly cut into the same rectangular shape together with the elastic core material 5 and the heat-fusible film 26 in accordance with a predetermined mark plane shape A indicated by a one-dot chain line in FIG. The elastic core material 5 is a GL type foamed polyurethane having a thickness of 7 mm. The heat-fusible film 26 with release paper is made of polyester and polyurethane, and is bonded after three-dimensional molding.

The mark material 12 and the elastic core material 5 are temporarily bonded in a flat press die 28 as shown in FIG. In the flat press mold 28, the compression gap at the time of temporary bonding is 6 mm, and this gap substantially corresponds to the thickness of the elastic core material 5. The press conditions for temporary bonding are pressing at a temperature of 100 ° C. to 150 ° C. and a pressure of 6 kg / cm ² for 10 to 20 seconds. The obtained temporary adhesion mark material 30 peels off the carrier film 14 after the press heat has cooled to room temperature.

  The flat temporary adhesion mark material 30 is preheated in a heating furnace (not shown) to prevent tearing of the surface layer sheet before three-dimensional molding. This preheating temperature is 50 to 80 ° C., and the preheating time is 10 seconds.

As shown in FIG. 7, the preheated temporary adhesion mark material 30 is placed in a reverse direction on a concave mold 34 of a press 32 and is three-dimensionally formed by a heat and pressure press to obtain a convex mark material 36. The pressing conditions are a temperature of 150 ° C. to 250 ° C. and a pressure of 6 kg / cm ² for 30 to 120 seconds.

Further, the convex mark material 36 is put on the concave mold 34 again to be adapted, and the heat-fusible adhesive film 26 with the release paper is stacked thereon and integrated by a press. The pressing conditions are a temperature of 90 ° C. to 130 ° C. and a pressure of 6 kg / cm ² for 5 seconds to 15 seconds. As a result, the heat-sensitive adhesive layer 6 with a release paper (FIG. 1) is laminated on the lower surface of the convex mark material 36, and finally is punched by a punching die (not shown) matched to the mark plane shape. The mark member 1 (FIG. 1) is completed.

  The obtained convex mark member 1 has a heat-sensitive adhesive layer 6 on its lower surface, as shown in FIG. In the convex mark member 1, the surface layer sheet 2, the fiber fabric 3, and the elastic core material 5 have a mutual contact portion 38 having a width of 2 mm around the entire mark, and the thickness of the contact portion is 0.5 mm. Further, the surface layer sheet 2 has a protruding portion 40 protruding upward by about 3 mm in the central portion of the cross section, and gently descends from the protruding central portion to the peripheral contact portion 38.

  The convex mark member 1 is thermocompression bonded to the adherend by the heat-sensitive adhesive layer 6 using a thermal transfer machine or an iron after peeling off the release paper. The convex mark member 1 has a soft touch as well as a rich three-dimensional effect, and has both design and cushioning properties.

When the convex mark material 36 formed in Example 1 is punched by a punching die (not shown) that matches the flat shape of the mark as it is, a convex mark member having no adhesive layer can be manufactured. The convex mark member can be sewn to the garment by sewing.
Also, as a frame laminating method, in this convex mark member, 0.5 mm of foamed polyurethane skin, which is the elastic core material 5 on the back side, is melted by a burner and directly heat-pressed to the woven or knitted fabric as an adherend. May be. This frame laminating method is low in cost and does not use a fusion resin or the like, and therefore has an advantage that the mark member does not get stuck and the resin does not bleed out.

  The convex mark member having no adhesive layer manufactured in Example 2 may be thermocompression bonded to the adherend by an adhesive resin laminating method. In the adhesive resin laminating method, the convex mark member is turned upside down, and the adhesive resin is sprayed or applied on the surface of the elastic core member 5 and then adhered to the adherend by heating and pressing. The adhesive resin laminating method is selected when the frame laminating method of Example 2 cannot be carried out with respect to the foamed urethane that does not respond to heat. For example, when open-cell foamed urethane is bonded to an adherend by an adhesive resin laminating method, the air permeability of the convex mark member can be maintained.

The convex mark member which does not have the adhesive layer manufactured in Example 2 may be thermocompression bonded to the adherend by a span fab lamination method. The span fab laminating method is applied when the elastic core material 5 is a nonwoven fabric or foamed EVA. In the spun fab laminating method, a spider web-like heat-fusible non-woven fabric with a basis weight of 12 g / m ² ± 10% is used, and this thin non-woven fabric is sandwiched between them when adhering to the woven or knitted fabric that is the adherend. Heat and pressurize, melt and bond the nonwoven fabric. The span fab laminating method is lightweight as a whole and can maintain air permeability.

  FIG. 3 shows a case where the surface layer sheet is the retroreflective sheet 10. In order to manufacture the retroreflective sheet 10, a commercially available bead sheet (trade name: Sparklite TR) in which fine transparent spheres are temporarily bonded to the entire surface of the base film 42 is used. In this sheet, the base film 42 is a polyester film having a thickness of 100 μm, and the temporary adhesive layer is made of a cellulosic resin having a thickness of 20 μm which is applied to the entire surface of the sheet and dried, and the temporary adhesive layer has a particle size of 30 to 60 μm. A transparent sphere array 44 made of glass beads is closely adhered.

  One or more afterglow generation layers 46 are provided by screen printing on a part of the transparent sphere array 44 of the sheet 42. The afterglow generation layer 46 is composed of 20% by weight of polyurethane resin, 2% by weight of polyester resin, 3% by weight of isocyanate resin, and 75% by weight of a yellow phosphorescent pigment. After screen printing in a predetermined pattern, it is dried at 40 ° C. for 20 minutes. Further, screen printing is performed twice with an ink containing a normal red pigment and a blue pigment, and a predetermined pattern layer 47 having a thickness of 6 to 30 μm is laminated.

  Next, the adhesive layer 48 is slightly larger than the planar shape of the design pattern on the afterglow generating layer 46, and is formed by screen printing. The adhesive layer 48 is made of 40% by weight polyurethane resin and 60% by weight polyamide resin, and screen-prints a paste-like thermoplastic ink using a 70-mesh screen plate. When dried at 40 ° C. for 20 minutes, the thickness of the adhesive layer 48 is 60 to 100 μm.

  The obtained retroreflective sheet 10 is thermocompression bonded to a polyester sheet (article number: CR7500) which is a reinforcing fiber fabric 3. This thermocompression bonding is performed using a thermal transfer machine. After the retroreflective sheet 10 and the fiber fabric 3 are pasted, a hot melt resin is screen printed on the surface of the reinforcing fabric using a screen mesh 70 mesh to form the heat-sensitive adhesive layer 24, thereby obtaining a mark material.

  The mark material of the retroreflective sheet 10 is roughly cut into a rectangular shape together with the elastic core material 5 and the heat-fusible film 26 in accordance with the mark plane shape. The elastic core material 5 is a GL type foamed polyurethane having a thickness of 7 mm. The heat-fusible film 26 with release paper is made of polyester and polyurethane.

The mark material and the elastic core material 5 are temporarily bonded by a flat press die 28. In the flat press die 28, the compression gap at the time of temporary bonding is 6 mm, and this interval substantially corresponds to the thickness of the elastic core material 5. The press conditions for temporary bonding are pressing at a temperature of 100 ° C. to 150 ° C. and a pressure of 6 kg / cm ² for 10 to 20 seconds.

  Thereafter, the retroreflective convex mark member is manufactured in the same manner as in Example 1. The convex mark member is peeled off the release paper, and then thermally bonded to the adherend by the heat-sensitive adhesive layer 6 using a thermal transfer machine or the like. The convex mark member has a pattern in which the entire afterglow generation layer 46 containing the phosphorescent pigment is covered with the transparent sphere array 44. This convex mark member is retroreflected extensively by the convex surface when illuminated by an automotive light, and can be easily seen from a distance, and the driver can be overlooked by the excellent phosphorescence even immediately after irradiation.
