Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a surface plate used for a sliding surface or a non-sliding surface of a ski or other ski equipment.

[0002]

2. Description of the Related Art Many of today's skis, snowboards, and other runners have a colorful and beautiful design on their surface, which is designed to arouse their willingness to purchase. Recently, its design is not limited to non-sliding surfaces,
It is also required to provide the sliding surface, and it is not a simple color or pattern, but an extremely complicated design using many colors like clothing and posters is required, and that color is also strictly reproduced. Has come to be required.

Conventional surface plates such as skis use a printing method using a pigment and a printing method using a dye. As a printing method using a pigment, ink and paint containing a pigment as a coloring material are diluted with a solvent on the back surface of a resin having high solvent resistance such as polyethylene resin, and then a design film is formed by a method such as screen printing. Is being done. In addition, in order to cope with recent more complex designs with more colors, a sublimable disperse dye that has been printed in advance on paper etc. is transferred onto the surface side of the surface material of opaque resin such as polybutylene terephthalate resin by heating and pressing means. A more vivid design is performed by the method of sublimation printing that penetrates.

[0004] The above-mentioned surface material, which has been screen-printed with a pigment on the back surface, has the advantage that the printed pattern itself is not easily damaged even if it is slightly scratched during use because the printing surface is the back surface of the material. However, in order to make multiple colors in the printing process, it is necessary to repeat printing and drying, and there is a problem that it is not possible to cope with complicated designs. Further, since it is necessary to use an organic solvent in the work, a resin having a low solvent resistance cannot be used as a surface material, the vividness of printing is not preferable, and the work environment is deteriorated. In addition, the latter method of printing with a dye on the front side of the surface material has the advantage of being able to handle complex multicolored designs and simplifying the printing process, but if the ski surface is scratched during use, the printed pattern itself will The problem of damage arises. Therefore, it is necessary to penetrate the print design deeper from the surface, but there is a problem that the printing time cannot be shortened because the heating and pressing time during sublimation printing is longer than the heat resistance of the material. In addition, since the design of the dye is on the ski surface, there is also the problem of poor weather resistance such as discoloration and discoloration of the dye due to direct sunlight, and the dye will seep out when touching a solvent etc. There was such a problem.

In order to solve such conventional problems, the present inventor has, in accordance with the invention of Japanese Patent Application No. 6-185086, a surface material having a transparent and at least a dye-dyeing plastic, and at least a dye. A backing material having a dyeable plastic is provided, and a printing surface formed by a dye is provided on one or both of the back surface of the surface material and the surface of the backing material, and the surface material and the backing material. We proposed a decorative board made by fusing and. According to the invention, printing is performed by sublimation printing or the like using a dye on the back side of a surface material having excellent transparency, the printed pattern is not easily damaged even by scratches during use, and a simple process is used. It was possible to print in a short time.

[0006]

When printing is performed on the back side of such a transparent plastic surface material, regardless of whether it is the non-sliding surface side or the sliding surface side, the printing of Sublimation printing with a dye may be applied to the back surface of a transparent surface material, and sublimation printing may be applied to the surface of a colored backing material. In the former case, even if an appropriate material is selected from the viewpoint of performance as a surface material, printing may be blurred and a clear design may not be possible when printing with a dye is considered. In this case, it is desirable that the plastic surface material has high transparency, and the higher the transparency, the better the design. However, depending on the type of plastic surface material, the dyeability is poor even with high transparency, and in the case of a resin with a particularly high gas permeability, there is the problem that the printing dye permeates and diffuses inside the resin and the design bleeds. A clear design cannot be obtained, and the designability cannot be improved. For example, in the case of a decorative plate used on the sliding surface side of skis, polyethylene resin, etc. is favorably selected in order to select materials that give priority to gliding properties, but polyethylene resin generally has a high gas permeability and dye stainability. The problem of design bleeding was unavoidable because of the poor quality. In addition, since the back surface of these surface materials is usually subjected to roughening processing such as sanding processing or embossing processing to improve adhesiveness, the dye penetration is not smooth during the above-mentioned sublimation printing, and unevenness or bleeding occurs. There was a problem.

When printing on the backing material side of the latter, there is a problem that the colorant of the colored backing material and the dye penetrating by the printing are mixed, and thus the desired color cannot be reproduced.

When sublimation printing is performed on a plastic sheet, the dye is heated to sublimate the printing, so that the plastic sheet is not deformed by heating. Therefore, sublimation printing is performed at a temperature lower than the heat resistant temperature of the resin. However, there is a problem that the heating time at the time of printing must be lengthened and the printing time cannot be shortened.

[0009]

Means for solving the above-mentioned problems according to the present invention are, as described in the claims, between a surface material which is a transparent plastic and a backing material which is a colored plastic. A decorative board for a sliding article, which is integrated by providing a dyeable fibrous body printed with a dye, and a dyeable fibrous body having a functional group in its molecular structure and a density of 1.0 or more. A dyeable fibrous material having a ventilation rate of 100 cc / square centimeter / se
and the like, and the like.

[0010]

The decorative board for skis and other skis according to the present invention is printed using a dye, so that printing can be carried out by a simple method such as sublimation printing by transfer, which saves labor in the printing process. it can. Further, since the printing surface is on the back surface side of the surface material, the printing is not easily impaired even by scratches or the like on the ski during use.

Since the dyeable fibrous material is printed and therefore has high heat resistance, printing can be performed at a high temperature, so that printing time can be shortened and workability and operability are improved. Further, it has high yellowing resistance due to sunlight and heat, and it is clear and can improve weather resistance. Since the dye is surely dyed on the fibrous body, even if the surface layer is a resin having a high gas permeability, the dye does not permeate to the surface layer side and the color does not bleed. In addition, there is no color mixing with the colorant on the backing material side.

When it is integrated with the surface material or the like, the melted plastic, adhesive or the like penetrates into the fibrous body, so that the interlayer strength can be increased and the strength as the structural material can be improved.

[0013]

FIG. 1 is a sectional view showing an embodiment in which the present invention is applied to a decorative plate having a non-sliding surface of a ski. Reference numeral 1 is a surface layer of polyamide resin having good transparency, 2 is a fibrous body layer made of non-woven polyester, 3 is an opaque (white) backing layer made of ABS resin, and 4 is printing with a dye. In this example, the fibrous body layer 2 is subjected to sublimation printing, and when the surface layer 1 and the backing layer 3 are extruded and molded, they are thermally fused and integrated. The decorative plate thus integrated is adhered to the structural member 5 of the ski body as shown in FIG. 2 to form a ski. Examples of polyamide resins having good transparency include polyamides 11 and 12, copolymers of polyamide 12 and polyamide 6, copolymers of polyether, and amorphous polyamide.

In the present invention, the fiber layer to be printed with a dye is preferably a fiber having a high dyeing property with a dye, and synthetic polymer fibers such as polyester, polyamide, vinylon, acetate, rayon and aramid, and cotton. ,
Natural polymer fibers such as hemp, wool and silk, and those containing hybrids thereof can also be used. In particular, a fibrous body made of polyester fiber has good dyeing properties, high heat resistance, high-temperature heating, short sublimation printing time, high rigidity, and good workability and operability. In addition, it is possible to perform printing with high resistance to yellowing due to sunlight and heat and clear and highly weather resistant. The fiber used for the dyeable fiber body is a place where a dye is deposited, that is, a fiber having a dyeing seat, and various functional groups which are present in the molecular structure of these fibers act as dye affinity groups and are bonded to the dye. Since the dyeing is performed, it is permeated and fixed without easily bleeding or fading. Therefore, the fibers constituting the dyeable fiber body are preferably fibers having a high polarity, a large number of functional groups, and a dense molecular structure and a density of 1.0 or more. As the functional group, a carbonyl group, a carboxyl group, an amino group, an amide group, an ester group, an ether group, a cyan group, a methyl group, a methylene group, a nitrile group, a nitro group, a vinyl group, an acetyl group, a butyryl group, a propionyl group, In addition to epoxy groups and hydroxyl groups, urethane bonds, carbon double bonds, etc. may be mentioned.

As the shape of the dyeable fibrous body, non-woven fabric, woven fabric, felt, paper and the like can be used. In particular, the non-woven fabric (spun bond) form has a constant porosity, little directionality, good dimensional stability, and excellent handleability during printing and clear printing. The fiber composition of the dyeable fiber body has an air flow rate of 100 cc / square centimeter / sec.
It is desirable to have the above-mentioned breathability. When the fibrous body is integrated in the middle of plastic such as surface material and lining material, the plastic penetrates into the voids of the fibrous body and can improve the adhesive strength between the layers, making it a highly durable decorative board. be able to.

The method of integration in this example is a method of heat-sealing with the surface material and the backing material plastic. In this case, even if the aeration amount of the dyeable fibrous material is 100 cc / square centimeter / sec or more, heat is applied. Although it can be fused, preferably 300 cc / square centimeter / sec or more has sufficient voids, so that the melted plastic easily penetrates and the interlayer strength can be further increased.
In addition, since heat fusion is performed with the fibrous body interposed, heat fusion can be easily performed even if the surface material and the back surface material are different plastics. Further, since re-sublimation due to high temperature heating at the time of heat fusion is printed on the above-mentioned dyeable fibrous body, it is extremely small and does not bleed on the surface layer.

As another method of integration, there is a method of impregnating a dyeable fibrous body with a thermosetting plastic and then curing and integrating it with a surface material and a backing material. In this case, since the thermosetting plastic is a liquid resin, the dyeable fibrous body can sufficiently penetrate into the voids with an air permeability of 100 cc / square centimeter / sec or more, and thus has sufficient interlayer strength after curing and integration. . Further, since the fibrous body also has a role of retaining a layer of liquid resin, the stability of adhesion is high. Here, as the thermosetting plastic, an epoxy resin composition is preferable, and a bisphenol A type epoxy resin having an epoxy equivalent of 130 to 500, preferably 1
Those of 40 to 270 can be applied. As the reactive curing agent, amine compounds such as aliphatic polyamine and polyamidoamine are preferable. These are excellent in transparency, adhesiveness, and weather resistance, and not only show the design clearly from the surface material, but can also be made into a highly durable decorative board.

A suitable combination of methods may be used, such as a method in which a dyeable fibrous body is heat-sealed to one of the surface material and the backing material, and the other is integrated with a thermosetting plastic. Further, in the present application, printing is performed by dyeing on the dyeable fibrous body by a method such as sublimation printing with a dye, and unlike the conventional printing for forming a coating film, penetration of a melted or liquefied resin is easy. Therefore, higher adhesion stability can be maintained by the integration method described above.

As an example of a method of printing with a dye, a pattern on which a sublimation dye is used as an ink is efficiently printed in advance, which is transferred onto the surface of the dyeable fibrous body of the present invention by heating and pressing. . As the dye, a disperse dye or an oil-soluble dye selected from azo dyes, pyrazolopyridine dyes, anthraquinone dyes, phthalocyanine dyes and the like can be appropriately used. Since printing by sublimation is performed by heating and pressurizing in this way, when printing is performed on a conventional plastic surface material, it is necessary to heat at a temperature lower than the heat resistant temperature of the resin, which inevitably increases the printing time. For example, if the surface material is a polyester resin, the heating temperature is 150 to 180.
The temperature was the limit, the heating time was 2-3 minutes, and the cooling time was further required. According to the present invention, printing with a dye is performed on a dyeable fibrous body, the heat resistance of the stretched fiber itself is increased, voids are provided between the fibers, and thermal deformation due to heating is caused between the fibers. As a result, the heating temperature can be made higher than in the case of printing on a conventional plastic sheet.

Further, since the dye sublimated and dispersed by heating due to the voids of the dyeable fibrous body acts from the periphery of each fiber, the dyeing is completed reliably and in a short time. For example, when the dyeable fiber body of the present application is a nonwoven fabric made of polyester fiber, the heating temperature is 200 to 210 ° C. and the heating time is 3
It can be completed in 0 seconds to 1 minute, the cooling time is short,
The printing process can be completed in a short time without thermal deformation. Here, the measurement of the air permeability of the dyeable fibrous material in the present application is carried out by the synthetic chemical fiber non-woven fabric test method of the Japan Chemical Fiber Association Standard 5.
9A method (Brazil method).

FIGS. 3 to 4 are views showing an example in which the present invention is applied to a ski sole material in another embodiment of the present invention. Two
1 is a transparent surface layer made of polyethylene resin, 22 is a fibrous body layer of non-woven polyester, 24 is dye printing by sublimation printing, and 23 is a backing layer made of white polyethylene resin. In this example, after the fibrous body layer 22 is heat-sealed to the backing layer 23, the sublimation printing 2 is performed on the fibrous body surface by the method described above.
4, the surface layer 21 and these are adhered by the same epoxy resin as described above as shown in FIG. The method of integration may be a method using an adhesive or a method using heat fusion.

The surface layer 21 is preferably made of a resin having a high transparency because it has a printed surface inside, and since it is a part that becomes a sliding surface of skis, etc., it has a good sliding property on a snow surface and abrasion resistance. Required. In this embodiment, the surface layer is made of polyethylene resin, but the higher the molecular weight of polyethylene is, the more the sliding performance is improved. Therefore, polyethylene having a molecular weight of 500,000 or more is particularly preferable in terms of the sliding performance. Polyethylene is a crystalline polymer and is a semitransparent resin having a density in the range of 0.91 to 0.97, and if the density is 0.95 or less, the transparency is determined by its crystallinity. Has good transparency. In particular, ultra-high-molecular-weight polyethylene having a molecular weight of 1,000,000 or more is preferable because of its outstanding transparency and gliding properties.

As the resin constituting the surface layer of the ski, there are resins such as polypropylene, ethylene vinyl acetate copolymer and ethylene / ethyl acrylate copolymer in addition to the above-mentioned polyethylene as an olefin resin, and ionomer resin, Examples thereof include polyurethane resins, polyvinyl chloride resins, copolymer resins mainly containing these, and polyamide resins such as polyamide resins and copolymer resins such as polyamide / polyether copolymers. These resins have good transparency and are suitable as a decorative plate for skis. Although some of these resins can be used at low cost, bleeding may occur due to insufficient dyeing due to the lack of functional groups that originally have affinity for dyes and large gas permeability. According to the present invention, it is possible to use any of these resins regardless of whether they are a surface material or a backing material.

Even if the surface material is a resin having a good dyeing property, it has been difficult to print from the back surface of the surface material when roughening the back surface of the surface material. Even in such a case, printing can be easily performed, and clear printing can be performed.

5 to 6 show still another embodiment in which the present invention is applied to a ski sole material. Similar to the above, 31 is a transparent surface layer made of polyethylene resin, 32 is a fibrous body layer made of polyester resin non-woven fabric, and 33 is a backing layer made of colored polyethylene resin. In this example, the fibrous body layer 3
Printing 34 by sublimation printing is performed on the surface of 2 in the same manner as above, and the printed fibrous body layer 32 and the surface material 31 are heat-sealed, and then a backing layer 33 of a further colored polyethylene resin
This is an example in which the are heat-sealed and integrated. Instead of being integrated by heat fusion, adhesion with an epoxy resin or the like may be used.

As the backing layer 35, a material having good coloring property and excellent adhesion to the ski body is preferable, but a polymer alloy of polyamide and ABS (ABS polyamide alloy) can be preferably applied in addition to polyethylene resin. A wide range of resins such as polyamide resin, ABS resin and ionomer resin can be applied. The backing layer is not limited to the use of a synthetic resin sheet, and instead, a colored epoxy resin or urethane resin may be applied to form the backing layer.

[0027]

As described above, in the decorative board for sliding equipment such as skis and snowboards of the present invention, dyeing is carried out by using dye on the dyeable fibrous body. It is possible to perform printing, and it is possible to easily print even with multiple colors and complicated designs, printing can be performed in an extremely short time, and workability and operability are also good. Further, the yellowing resistance of the dye to sunlight and heat is excellent, and the saturation and sharpness of printing can be maintained as desired. The dye is stable and does not bleed on the fiber portion of the dyeable fibrous body, and the printing does not become unclear. Since the printing surface is on the back surface side of the surface material, the easily printed design will not be impaired by scratches or the like during use. In addition, since the printing dye does not penetrate into the surface material side, clear printing can be performed even if the surface material is a material with high gas permeability, and a material with excellent transparency and glidability can be selected from a wide range of plastics. You can choose freely. Further, since the resin penetrates into the voids of the dyeable fibrous body and is integrated therewith, it is possible to provide a decorative board having high durability.
