Description

Decorated body and method for manufacturing the same

[0001] The present invention relates to a decorated body including a woven fabric layer or a knitted fabric layer and a base material. The present invention also relates to a method for manufacturing a decorated body including a woven fabric layer or a knitted fabric layer and a base material.

[0002] In vehicles, electronic devices, building materials, furniture, etc., articles in which exterior members or interior members are disposed on the surface portion are used. When the exterior member or interior member is a decorative member, a decorated body (article) decorated with the decorative member can be obtained. As the decorative member, a resin sheet, artificial leather, etc. are used. For example, when the decorative member is the artificial leather, a surface pattern peculiar to the artificial leather is imparted to the surface of the decorated body. The decorative member enhances the aesthetic property of the decorated body.

[0003] Patent Document 1 below discloses a decorated body including a decorative portion of artificial leather and a method for manufacturing the same. In Patent Document 1, in order to obtain a decorated body, artificial leather with a protective film is used as a preform molded body. The artificial leather with a protective film includes artificial leather and a protective film. The artificial leather includes a nonwoven fabric of ultrafine fibers having a thickness of 250 μm or more and a resin layer having a three-dimensional decorative surface. The resin layer has an embossed concavo-convex surface. The protective film is formed by coating resin so that the resin is filled in the concave portion of the embossed concavo-convex surface.

[0004] The method for manufacturing the decorated body described in Patent Document 1 includes a first step of disposing the preform molded body in a cavity of a mold, a second step of molding an in-mold molded body by injecting molten resin onto the artificial leather of the preform molded body, and a third step of obtaining a decorated body by peeling the protective film from the in-mold molded body. The obtained decorated body includes the artificial leather and a base material in which the molten resin has solidified.

[0005] Japanese Patent Application Laid-Open No. 2016-124156

[0006] In the decorative body described in Patent Document 1, the substrate in which the molten resin has solidified is bonded to the artificial leather (nonwoven fabric). In the decorative body described in Patent Document 1, since a nonwoven fabric is used, the adhesion between the artificial leather and the substrate is not easily improved.

[0007] Furthermore, in the decorative body described in Patent Document 1, if the material of the artificial leather and the material of the base material are different materials, the adhesion between the artificial leather and the base material may be low. For this reason, when the decorative body is used, the artificial leather may peel off from the base material.

[0008] Furthermore, in the decorative body described in Patent Document 1, if the material of the artificial leather and the material of the base material are different materials, it is necessary to separate the artificial leather and the base material in order to reuse the decorative body. For this reason, the decorative body described in Patent Document 1 has the problem of high recycling costs and low recyclability.

[0009] The object of the present invention is to provide a decorative body that can be made to look good by being decorated with a woven or knitted layer, can improve the adhesion between the woven or knitted layer and the base material, and can improve the recyclability of the decorative body. Another object of the present invention is to provide a method for manufacturing a decorative body that can be made to look good by being decorated with a woven or knitted layer, can improve the adhesion between the woven or knitted layer and the base material, and can improve the recyclability of the decorative body.

[0027] The present invention provides a method for manufacturing a decorative body, comprising the step of placing a woven fabric layer or knitted fabric layer in a mold. The present invention provides a method for manufacturing a decorative body, comprising the woven fabric layer or knitted fabric layer and a base material containing the first resin, wherein the base material is in contact with the first surface of the woven fabric layer or knitted fabric layer, by placing a first resin for forming a base material in a molten state on the first surface of the woven fabric layer or knitted fabric layer in the mold and molding it. In the method for manufacturing a decorative body according to the present invention, the woven fabric layer or knitted fabric layer contains a second resin.

[0028] Figure 1(a) is a schematic perspective view showing a decorative body according to the first embodiment of the present invention, and Figure 1(b) is a schematic cross-sectional view showing a decorative body according to the first embodiment of the present invention. Figure 2 is a schematic cross-sectional view showing a decorative body according to the second embodiment of the present invention. Figure 3 is a schematic cross-sectional view showing a decorative body according to the third embodiment of the present invention. Figure 4 is an enlarged cross-sectional view of a decorative body according to the first embodiment of the present invention. Figure 5 is an image of a decorative body according to the fourth embodiment of the present invention.

[0029] The details of the present invention will be described below.

[0030] (Decorative body) The decorative body according to the present invention comprises a woven fabric layer or a knitted fabric layer and a base material containing a first resin. In the decorative body according to the present invention, the woven fabric layer or knitted fabric layer contains a second resin. In the decorative body according to the present invention, the base material is in contact with the first surface of the woven fabric layer or knitted fabric layer.

[0031] In a first specific aspect of the decorative body according to the present invention, the second resin contained in the woven or knitted layer and the first resin contained in the base material are of the same type. In a second specific aspect of the decorative body according to the present invention, the combination of the second resin contained in the woven or knitted layer and the first resin contained in the base material is a combination of polyolefin resin and polyolefin resin, a combination of ABS resin and ABS resin, or a combination of polycarbonate resin and polycarbonate resin.

[0032] Therefore, the decorative body according to the present invention satisfies either the following configuration (1) or the following configuration (2). Configuration (1): The second resin contained in the woven or knitted layer and the first resin contained in the base material are of the same type. Configuration (2): The combination of the second resin contained in the woven or knitted layer and the first resin contained in the base material is a combination of polyolefin resin and polyolefin resin, a combination of ABS resin and ABS resin, or a combination of polycarbonate resin and polycarbonate resin.

[0033] In the decorative body according to the present invention, the appearance can be improved by decoration with the woven or knitted layer. In the decorative body according to the present invention, the characteristic appearance of woven or knitted fabric can be imparted to the outside of the base material.

[0034] Furthermore, since the decorative body according to the present invention is provided with the above-described structure, the adhesion between the woven or knitted layer and the substrate can be improved. For example, when a substrate is adhered to the surface of a nonwoven fabric, the adhesion between the nonwoven fabric and the substrate is not easily improved. In the decorative body according to the present invention, a woven or knitted layer is used instead of a nonwoven fabric, so the adhesion between the woven or knitted layer and the substrate can be improved.

[0035] Furthermore, the surface of the woven or knitted fabric in the woven or knitted fabric layer typically has recesses or voids. Adhesion can also be improved by adhering the substrate to the surface of the woven or knitted fabric layer where recesses or voids exist. This is thought to be because the substrate (the first resin forming the substrate) can easily penetrate into the recesses or voids of the woven or knitted fabric layer.

[0036] Furthermore, because the second resin contained in the woven or knitted layer and the first resin contained in the substrate are of the same type, the affinity between the first and second resins is excellent, resulting in significantly higher adhesion. Moreover, because the combination of the second resin contained in the woven or knitted layer and the first resin contained in the substrate is a combination of polyolefin resin and polyolefin resin, an ABS resin and ABS resin, or a combination of polycarbonate resin and polycarbonate resin, the affinity between the first and second resins is excellent, resulting in significantly higher adhesion.

[0037] Furthermore, since the decorative body according to the present invention is provided with the above-described configuration, the recyclability of the decorative body can be enhanced. In particular, the recyclability of the decorative body is enhanced when the second resin contained in the woven or knitted layer and the first resin contained in the base material are of the same type. Furthermore, the recyclability of the decorative body is enhanced when the combination of the second resin contained in the woven or knitted layer and the first resin contained in the base material is a combination of polyolefin resin and polyolefin resin, a combination of ABS resin and ABS resin, or a combination of polycarbonate resin and polycarbonate resin. When reusing the decorative body, it is not necessary to separate the woven or knitted layer and the base material.

[0038] Furthermore, since the decorative body according to the present invention uses a woven or knitted fabric layer instead of a nonwoven fabric, the strength of the surface on the woven or knitted fabric side of the decorative body can be increased.

[0039] Non-woven fabrics are prone to getting dirty, and the dirt on non-woven fabrics may be difficult to remove by wiping. In contrast, in the decorative body according to the present invention, a woven fabric layer or a knitted fabric layer is used instead of a non-woven fabric, so that the dirt on the surface of the woven fabric layer or the knitted fabric layer side of the decorative body can be prevented, and the dirt on the surface of the woven fabric layer or the knitted fabric layer side can be easily removed.

[0040] Hereinafter, specific embodiments of the present invention will be described. In FIG. 1 and the figures described later, different parts can be replaced with each other.

[0041] FIG. 1(a) is a perspective view schematically showing a decorative body according to the first embodiment of the present invention. FIG. 1(b) is a cross-sectional view schematically showing the decorative body according to the first embodiment of the present invention. FIG. 1(b) is a cross-sectional view taken along the line I-I shown in FIG. 1(a).

[0042] The decorative body 1 shown in FIG. 1 includes a woven fabric layer or a knitted fabric layer 11 and a base material​​​​​​​​Figure 4 is an enlarged cross-sectional view of a decorative body 1 according to the first embodiment of the present invention. The first surface 11a of the woven or knitted layer 11 usually has recesses or voids (voids if there were no base material) that originate from the woven or knitted material. On the first surface 11a of the woven or knitted layer 11, the base material 12 also penetrates into the recesses or voids that originate from the woven or knitted material. As a result, on the first surface 11a of the woven or knitted layer 11, the space between adjacent threads is a non-void space.

[0046] The first surface 11a of the woven or knitted layer 11 is flat. The second surface of the woven or knitted layer 11, opposite to the first surface 11a, is flat. In this regard, when considering the overall shape, neglecting any recesses or voids derived from the woven or knitted fabric, the first surface 11a and the second surface can be considered flat.

[0047] The decorative body 1 has an X direction (e.g., vertical direction), a Y direction (e.g., horizontal direction), and a Z direction (e.g., thickness direction). The X and Y directions are perpendicular, the X and Z directions are perpendicular, and the Y and Z directions are perpendicular. The main surface of the decorative body 1 is parallel to the X and Y directions. The thickness direction of the decorative body 1 is the Z direction. The main surface of the woven or knitted layer 11 is parallel to the X and Y directions. The thickness direction of the woven or knitted layer 11 is the Z direction. The main surface of the base material 12 is parallel to the X and Y directions. The thickness direction of the base material 12 is the Z direction.

[0048] In the decorative body 1, the thickness (average thickness) of the woven or knitted layer 11 is thinner than the thickness (average thickness) of the base material 12. In the decorative body 1, the thickness (average thickness) of the woven or knitted layer 11 is relatively thin. In the decorative body 1, the base material 12 is the base material layer. The thickness (average thickness) of the base material 12 is relatively thin. Therefore, the thickness (average thickness) of the decorative body 1 is relatively thin. The decorative body 1 has an X direction and a Y direction on a plane and is a planar object, not a three-dimensional object. The decorative body 1 has a two-dimensional shape.

[0049] Figure 2 is a schematic cross-sectional view showing a decorative body according to a second embodiment of the present invention.

[0050] The decorative body 1A shown in Figure 2 comprises a woven or knitted layer 11A and a base material 12A. The woven or knitted layer 11A contains a second resin. The base material 12A contains a first resin. The base material 12A is positioned on the first surface 11Aa side of the woven or knitted layer 11A. The base material 12A is in contact with the first surface 11Aa of the woven or knitted layer 11A.

[0051] The decorative body 1A satisfies either the above-described configuration (1) or configuration (2).

[0052] A woven or knitted fabric layer 11A is arranged on the first surface of the base material 12A. A woven or knitted fabric layer 11A is arranged on the side surface of the base material 12A. The side surface of the base material 12A is not exposed. A woven or knitted fabric layer is not arranged on the second surface of the base material 12A, which is opposite to the first surface. The second surface of the base material 12A is exposed.

[0053] The base material 12A has a corner where the first surface and side surface of the base material 12A meet. The woven or knitted layer 11A is placed on the corner of the base material 12A. Therefore, the woven or knitted layer 11A has a corner on the corner of the base material 12A. In other words, the woven or knitted layer 11A has a bent portion on the corner of the base material 12A.

[0054] In the decorative body 1A, the thickness (average thickness) of the woven or knitted layer 11A is thinner than the thickness (average thickness) of the base material 12A. In the decorative body 1A, the thickness (average thickness) of the woven or knitted layer 11A is relatively thin. In the decorative body 1A, the thickness (average thickness) of the base material 12A is relatively thick. Therefore, the thickness of the decorative body 1A is relatively thick. The thickness (average thickness) of the decorative body 1A in the Z direction, which is perpendicular to the X and Y directions, is relatively thick. Therefore, the decorative body 1A is not a planar object, but a three-dimensional object. The decorative body 1A has a three-dimensional shape.

[0055] Figure 3 is a schematic cross-sectional view showing a decorative body according to a third embodiment of the present invention.

[0056] The decorative body 1B shown in Figure 3 comprises a woven or knitted layer 11B and a base material 12B. The woven or knitted layer 11B contains a second resin. The base material 12B contains a first resin. The base material 12B is positioned on the first surface 11Ba side of the woven or knitted layer 11B. The base material 12B is in contact with the first surface 11Ba of the woven or knitted layer 11B.

[0057] The decorative body 1B satisfies either the configuration (1) or configuration (2) described above.

[0058] A woven or knitted fabric layer 11B is arranged on the first surface of the base material 12B. The first surface of the base material 12B is convex. The thickness of the base material 12B increases from the edges towards the center. The first surface of the base material 12B is curved. The second surface of the woven or knitted fabric layer 11B, opposite to the first surface 11Ba, is convex. The second surface of the woven or knitted fabric layer 11B is curved. The first surface 11Ba of the woven or knitted fabric layer 11B is concave. The first surface 11Ba of the woven or knitted fabric layer 11B is curved. No woven or knitted fabric layer is arranged on the second surface of the base material 12B, opposite to the first surface. The second surface of the base material 12B is exposed.

[0059] In the decorative body 1B, the thickness (average thickness) of the woven or knitted layer 11B is thinner than the thickness (average thickness) of the base material 12B. In the decorative body 1B, the thickness (average thickness) of the woven or knitted layer 11B is relatively thin. In the decorative body 1B, the base material 12B has parts that are thicker and parts that are thinner, but overall, the thickness (average thickness) of the base material 12B is relatively thick. Therefore, the thickness of the decorative body 1B is relatively thick. The thickness of the decorative body 1B in the Z direction, which is perpendicular to the X and Y directions, is relatively thick. Therefore, the decorative body 1B is not a planar object, but a three-dimensional object. The decorative body 1B has a three-dimensional shape.

[0060] As shown in Figures 1 to 3, various shapes can be used for the decorative element. Furthermore, various other shapes can be used besides those shown in Figures 1 to 3.

[0061] Figure 5 is an image of a decorative body according to the fourth embodiment of the present invention.

[0062] In the decorative body shown in Figure 5, the surface pattern of the second surface opposite to the first surface of the woven or knitted layer is a tatami mat pattern, and the decorative body is an interior component in a vehicle. In Figure 5, the decorative body is attached to the vehicle body as an interior component. By using a decorative body with a tatami mat pattern as an interior component in a vehicle, the tatami mat pattern is given to the vehicle as a new appearance that has not been adopted conventionally.

[0063] The following describes the details of the woven or knitted layer in the decorative body, the base material, other details of the decorative body, and the manufacturing method of the decorative body.

[0064] (Details of the woven or knitted layer) The decorative body comprises the woven or knitted layer. The woven or knitted layer is different from a nonwoven fabric. The woven layer includes a woven fabric. The knitted layer includes a knitted fabric.

[0065] In this specification, "textile" means a fabric woven in which warp threads and weft threads intersect at any angle.

[0066] In this specification, "knitted fabric" means a fabric formed by creating loops with a single thread and connecting these loops.

[0067] The woven or knitted layer may be a woven layer or a knitted layer. From the viewpoint of further improving the adhesion between the woven or knitted layer and the base material, and further improving the strength, abrasion resistance and shape retention of the woven or knitted layer, it is preferable that the woven or knitted layer is a woven layer, and more preferably a woven layer having warp threads and weft threads.

[0068] The woven or knitted fabric layer has a first surface and a second surface opposite to the first surface. The woven or knitted fabric layer has the characteristic appearance of a woven or knitted fabric. The woven or knitted fabric layer is a decorative member. In the decorative body, the second surface of the woven or knitted fabric layer is aesthetically pleasing when viewed.

[0069] The woven or knitted layer contains a second resin.

[0076] If the second resin is a polymer, the melting point of the second resin can be adjusted by the degree of polymerization, etc.

[0077] The melting point of the second resin contained in the woven or knitted fabric layer can be measured using a differential scanning calorimeter (for example, Seiko Instruments' "SC220C") according to the following procedure. First, 10 mg of the second resin is heated from 25°C to 250°C at a heating rate of 10°C / min and held at 250°C for 3 minutes. Next, the second resin is cooled from 250°C to 25°C at a cooling rate of 10°C / min and held at 25°C for 3 minutes. Subsequently, the second resin is reheated from 25°C to 250°C at a heating rate of 10°C / min, and the temperature at the peak of the endothermic peak during this reheating process is taken as the melting point of the second resin.

[0078] From the viewpoint of further improving the strength, abrasion resistance and shape retention of the woven or knitted layer, it is preferable that the woven or knitted layer has yarn containing the second resin. From the viewpoint of further improving the strength, abrasion resistance and shape retention of the woven or knitted layer, it is preferable that the yarn is woven or knitted in the woven or knitted layer.

From the viewpoint of further improving the strength, abrasion resistance and shape retention of the woven layer, it is preferable that the woven layer has warp threads containing the second resin and weft threads containing the second resin. From the viewpoint of further improving the strength, abrasion resistance and shape retention of the woven layer, it is preferable that the warp threads and weft threads are woven in the woven layer. From the viewpoint of further improving the strength, abrasion resistance, and shape retention of the above-mentioned woven layer, it is preferable that the warp threads and weft threads in the above-mentioned woven layer are woven regularly.

[0079] From the viewpoint of further improving the moldability of the decorative body, further improving the adhesion between the woven or knitted layer and the base material, and further improving the abrasion resistance of the decorative body, the second resin-containing yarn is preferably artificial rush yarn, preferably resin rush yarn, and more preferably both artificial and resin rush yarn. In particular, it is preferable that the weft yarn of the woven layer is the rush yarn.

[0137] The following woven or knitted layers and a first resin for forming the following substrates were prepared.

[0138] A resin composition was prepared containing 100 parts by weight of polypropylene resin (Novatec PP Series FX4GF, manufactured by Nippon Polypropylene Co., Ltd., MFR 5.0 g / 10 min), 27 parts by weight of calcium carbonate (MAX Series, manufactured by Takehara Chemical Industry Co., Ltd.), and 2.0 parts by weight of azo inorganic pigment (PPM0866, manufactured by Toyo Ink Co., Ltd.). This resin composition was supplied to a single-screw compounding extruder with a screw diameter (φ: 90 mm) and compounded and extruded at 210°C to obtain a polypropylene resin film (thickness 100 μm).

[0139] The obtained polypropylene resin film was supplied to a hot plate type uniaxial stretching apparatus set to 120°C and stretched five times to obtain a tape-like material (thickness 20 μm). The obtained tape-like material was folded in the uniaxial stretching direction and passed through a through hole with a diameter of 2.0 mm to form a string-like shape, obtaining a molded body. This molded body was supplied to a heating member having a circular cross-section void with a diameter of 1.0 mm, heated to 300°C, and passed through the void at a speed of 65 m / min to obtain artificial rush grass.

[0140] Pellets (cylindrical shape, 2 mm in diameter and 2 mm in height) of polypropylene resin (Novatec PP Series MA1B, manufactured by Nippon Polypropylene Co., Ltd., MFR 21 g / 10 min) were prepared. These pellets were supplied from the raw material supply port of a melt spinning extruder, and after melt-mixing in the extruder, melt spinning was performed. The fibers were then stretched and cut using a stretcher to produce polypropylene fibers (single fiber fineness of approximately 1.3 dtex, fiber length of 38 mm).

[0141] The obtained polypropylene fibers were subjected to a blending and beating process, a carding process, a drawing process, and a roving process in sequence to obtain roving yarn (50 gelen / 12 yd, 100% polypropylene fiber by weight). Next, two strands of the obtained roving yarn (100% polypropylene fiber by weight) were used in a ring spinning machine equipped with a compact spinning system. A 40x draft was applied, and the fibers were concentrated by drawing air in the direction of the roving's movement. Then, the yarn was twisted with a twist coefficient of 3.4 to produce polypropylene spun yarn (English cotton count 40s).

[0142] The obtained artificial rush was used as the weft and the obtained polypropylene spun yarn as the warp. The weft and warp were plain woven with a warp spacing of 4 mm and a weft count of 90 threads / 10 cm to obtain an anisotropic tatami mat surface (thickness 2 mm, woven layer (A1)).

[0143] (Nonwoven Fabric) Polypropylene resin (Novatec PP Series BC05B, manufactured by Nippon Polypropylene Co., Ltd., MFR 60 g / 10 min) was extruded by the spunbond method with a nozzle diameter of 0.4 mm, a single-hole discharge rate of 0.56 g / min, and a spinning temperature of 205°C. The extruded filament group was pulled using a high-speed airflow traction device with an air jet to obtain a long-fiber web (average single-fiber fineness 1.5 dtex). Next, the obtained web was passed between a flat roll and an embossing roll (pattern specifications: diameter 0.425 mm circular, staggered arrangement, transverse pitch 2.1 mm, longitudinal pitch 1.1 mm, compression area ratio 6.3%), and the fibers were bonded together under conditions of a temperature of 135°C and a linear pressure of 35 kgf / cm to form a spunbond nonwoven fabric (basis weight 17 g / m²). ２ A nonwoven fabric (X) was obtained.

[0145] (Example 1) The above-mentioned woven fabric layer (A1) was placed on the cavity surface of a mold set to 40°C. Insert molding was performed by injecting polypropylene resin (B1) at a resin temperature of 190°C onto the first surface of the woven fabric layer (A1) inside the mold. A decorative body (C1) was obtained comprising the above-mentioned woven fabric layer (A1) containing the polypropylene resin and a base material (B1) containing the polypropylene resin (B1), wherein the base material (B1) is in contact with the first surface of the woven fabric layer (A1).

[0146] (Comparative Example 1) A decorative body (D1) was obtained in the same manner as in Example 1, except that the nonwoven fabric (X) was used instead of the woven fabric layer (A1), and the base material (B1) comprising the nonwoven fabric (X) and the polypropylene resin (B1), wherein the base material (B1) is in contact with the first surface of the nonwoven fabric (X).

[0147] (Evaluation) (1) Appearance of the decorative body The decorative body (C1) obtained was decorated with a woven fabric layer (A1) and had excellent aesthetics.

[0148] (2) Adhesion between the woven or knitted layer (or nonwoven fabric) and the substrate in the decorative body. The adhesive strength between the woven layer (A1) or nonwoven fabric (X) and the substrate (B1) in the obtained decorative bodies (C1) and (D1) was evaluated. As a result, the adhesive strength of decorative body (C1) was higher than that of decorative body (D1). (Adhesive strength: Decorative body (C1) > Decorative body (D1))

[0149] (3) Recyclability of the decorative body In the obtained decorative body (C1), since the second resin of the fabric layer (A1) and the first resin of the base material (B1) are of the same type, the decorative body (C1) could be reused without separating the fabric layer (A1) and the base material (B1).
