Description

Decorative body and method for manufacturing a decorative body

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

[0002] In vehicles, electronic equipment, building materials, and furniture, articles are used in which exterior or interior components are placed on the surface. When the exterior or interior component is a decorative component, a decorated article is obtained. Examples of such decorative components include resin sheets and artificial leather. For example, when the decorative component is artificial leather, the surface of the decorated article is given a surface pattern characteristic of artificial leather. The decorative component enhances the aesthetic appeal of the decorated article.

[0003] Patent Document 1, described below, discloses a decorative body having an artificial leather decorative part and a method for manufacturing the same. In Patent Document 1, artificial leather with a protective film is used as a preformed molded body to obtain the decorative body. The artificial leather with a protective film comprises 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 uneven surface. The protective film is formed by coating it with resin so that the resin is filled into the recesses of the embossed uneven surface.

[0004] The method for manufacturing a decorative body described in Patent Document 1 comprises a first step of placing the preformed molded body in the cavity of a mold, a second step of forming an in-mold molded body by injecting molten resin onto the artificial leather of the preformed molded body, and a third step of obtaining a decorative body by peeling off the protective film from the in-mold molded body. The resulting decorative body comprises the artificial leather and a base material from which the molten resin has solidified.

[0005] Japanese Patent Publication 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, the decorative body described in Patent Document 1 may have low abrasion resistance in the decorative portion of the artificial leather containing nonwoven fabric. Therefore, when the decorative body is used, scratches may occur on the surface. As a result, the aesthetic appeal of the decorative body may be reduced.

[0008] The object of the present invention is to provide a decorative body that can be made to look good by decoration with a woven or knitted layer, and that can have its abrasion resistance improved. The object of the present invention is also to provide a method for manufacturing a decorative body.

[0009] This specification discloses the following decorative elements and methods for manufacturing them.

[0022] Item 13. The decorative body according to any one of items 1 to 8, wherein the surface pattern of the second surface of the woven or knitted layer opposite to the first surface is a tatami mat pattern, and the decorative body is an interior or exterior component in a vehicle or electronic device.

[0023] Item 14. A method for manufacturing a decorative body according to any one of items 1 to 13, comprising the steps of: placing the woven or knitted layer in a mold; and molding the woven or knitted layer in a mold by placing a first resin for forming a base material in a molten state on the first surface of the woven or knitted layer, thereby obtaining a decorative body comprising the woven or knitted layer and a base material containing the first resin, wherein the base material is placed on the first surface side of the woven or knitted layer.

[0024] The decorative body according to the present invention comprises a woven or knitted layer and a base material containing a first resin, wherein the base material is arranged on the first surface side of the woven or knitted layer. In the decorative body according to the present invention, the woven or knitted layer contains yarn having a diameter of 500 μm or more. Because the decorative body according to the present invention has the above configuration, the appearance can be improved by decoration with the woven or knitted layer, and the abrasion resistance of the decorative body can be increased.

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 a schematic cross-sectional view showing a decorative body according to the fourth embodiment of the present invention. Figure 5 is an enlarged cross-sectional view of a decorative body according to the first embodiment of the present invention. Figure 6 is a diagram illustrating the part for determining the void ratio in the woven or knitted layer. Figure 7 is an image of a decorative body according to the fourth embodiment of the present invention.

[0026] The details of the present invention will be described below.

[0027] (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 base material is arranged on the first surface side of the woven fabric layer or knitted fabric layer.

[0028] In the decorative body according to the present invention, the woven or knitted layer contains yarn having a diameter of 500 μm or more.

[0029] 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.

[0030] In decorative bodies equipped with a nonwoven fabric decorative portion, the nonwoven fabric portion may have low abrasion resistance. As a result, the surface of the decorative body may be scratched when it is used. Consequently, the aesthetic appeal of the decorative body may be reduced. In contrast, the decorative body according to the present invention uses a woven fabric layer or a knitted fabric layer instead of a nonwoven fabric, and since the woven fabric layer or knitted fabric layer contains yarn of a specific diameter, the abrasion resistance of the decorative body can be improved. In the decorative body according to the present invention, the abrasion resistance of the decorative body can be improved due to the woven fabric layer or knitted fabric layer.

[0031] Furthermore, since the decorative body according to the present invention is provided with the above configuration, when bonding the woven or knitted layer to the substrate, the adhesion between the woven or knitted layer and the substrate can be improved. For example, when a substrate is bonded to the surface of a nonwoven fabric, the adhesion between the nonwoven fabric and the substrate may not be very good. 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. When bonding an intermediate layer to the woven or knitted layer, the adhesion between the woven or knitted layer and the intermediate layer can also be improved.

[0032] The surface of the woven or knitted fabric layer typically has recesses or voids. Adhesion can be improved by bonding a substrate to the surface of the woven or knitted fabric layer where these 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. Adhesion between the woven or knitted fabric layer and the intermediate layer can also be improved when bonding an intermediate layer to the woven or knitted fabric layer.

[0033] 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 can be increased.

[0034] Nonwoven fabrics are prone to soiling, and soiling of nonwoven fabrics can be difficult to remove by wiping. In contrast, the decorative body according to the present invention uses a woven or knitted fabric layer instead of a nonwoven fabric, and furthermore, the diameter of the yarn in the woven or knitted fabric layer is within a specific range, so soiling of the surface on the woven or knitted fabric side of the decorative body can be prevented, and any soiling of the surface on the woven or knitted fabric side can be easily removed.

[0035] From the viewpoint of further improving the abrasion resistance and breathability of the decorative body, it is preferable that the void ratio in the woven or knitted layer is 5% or more. Preferably, the void ratio in the woven or knitted layer is 6% or more, more preferably 7% or more, and even more preferably 9% or more. If the void ratio in the woven or knitted layer is above the lower limit, the abrasion resistance and breathability of the decorative body can be further improved. There is no particular upper limit to the void ratio in the woven or knitted layer. The void ratio in the woven or knitted layer may be 20% or less, or 15% or less. If the void ratio in the woven or knitted layer is below the upper limit, the strength of the woven or knitted layer side of the decorative body can be further improved. The range of the void ratio in the woven or knitted layer can be set by appropriately selecting the lower limit and upper limit values.

[0036] The porosity of the woven or knitted layer can be determined by cross-sectional observation of the woven or knitted layer.

[0037] FIG. 6 is a diagram for explaining a portion for obtaining the porosity in a woven layer or a knitted layer. The decorated body 51 shown in FIG. 6 includes a woven layer or a knitted layer 61 and a base material 62. The base material 62 is disposed on the first surface 61a side of the woven layer or the knitted layer 61. When obtaining the porosity in the woven layer or the knitted layer 61, taking the area of the portion surrounded by the broken line in FIG. 6 as 100%, in the portion surrounded by the broken line, the portion where no object (woven or knitted fabric and the first resin) exists is regarded as a void. The broken line on the first surface 61a side of the woven layer or the knitted layer 61 is a line connecting the surfaces of adjacent yarns with a straight line. The broken line on the side opposite to the first surface 61a side of the woven layer or the knitted layer 61 is a line connecting the surfaces of adjacent yarns with a straight line. On the first surface 61a side of the woven layer or the knitted layer 61, since the first resin of the base material 62 has penetrated, there is no void between adjacent yarns. On the first surface 61a side of the woven layer or the knitted layer 61, the portion where the first resin of the base material 62 has penetrated is a non-void portion. On the side opposite to the first surface 61a side of the woven layer or the knitted layer 61, void portions exist between adjacent yarns. Also, in the woven layer or the knitted layer 61, one yarn is formed of a plurality of fibers. Therefore, void portions also exist between the plurality of fibers within the yarn. The plurality of fiber portions within the yarn are non-void portions. Note that when one yarn of the woven layer or the knitted layer is not formed of a plurality of fibers (that is, one yarn is formed of a single fiber), there may be voids within one yarn, and there may be no voids within one yarn.

[0038] Hereinafter, specific embodiments of the present invention will be described. In FIG. 1 and the figures described later, different portions can be replaced with each other.

[0039] FIG. 1(a) is a perspective view schematically showing a decorated body according to a first embodiment of the present invention. FIG. 1(b) is a cross-sectional view schematically showing the decorated 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).

[0040] The decorated body 1 shown in Fig. 1 includes a woven or knitted layer 11 and a base material 12. The woven or knitted layer 11 preferably contains a second resin. The base material 12 contains a first resin. The base material 12 is disposed on the first surface 11a side of the woven or knitted layer 11. The base material 12 is in contact with the first surface 11a of the woven or knitted layer 11. The woven or knitted layer 11 and the base material 12 are in contact. Further, the woven or knitted layer 11 and the base material 12 are adhered to each other.

[0041] In the decorated body 1, the woven or knitted layer 11 contains yarns having the above-described specific diameter.

[0042] The woven or knitted layer 11 is disposed on the first surface of the base material 12. The woven or knitted layer 11 is not disposed on the side surface of the base material 12. The side surface of the base material 12 is exposed. The woven or knitted layer is not disposed on the second surface of the base material 12 on the opposite side to the first surface side of the base material 12. The second surface of the base material 12 is the surface on the opposite side to the woven or knitted layer 11 side. The second surface of the base material 12 is exposed.

[0043] Fig. 5 is an enlarged cross-sectional view of the decorated body 1 according to the first embodiment of the present invention. Usually, recesses or voids (voids in the case where the base material does not exist) derived from the woven or knitted fabric exist on the first surface 11a of the woven or knitted layer 11. In the first surface 11a of the woven or knitted layer 11, the base material 12 also enters into the recesses or voids derived from the woven or knitted fabric. As a result, between adjacent yarns on the first surface 11a of the woven or knitted layer 11, it becomes a non-void portion.

[0044] The first surface 11a of the woven or knitted layer 11 is a flat surface. The second surface on the opposite side to the first surface 11a of the woven or knitted layer 11 is a flat surface. In this regard, when the recesses or voids derived from the woven or knitted fabric are ignored and grasped in the overall shape, the first surface 11a and the second surface can be regarded as flat surfaces.

[0045] 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.

[0046] 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.

[0047] Figure 2 is a schematic cross-sectional view showing a decorative body according to a second embodiment of the present invention.

[0048] 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 preferably 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.

[0049] In the decorative body 1A, the woven or knitted layer 11A contains yarn having the specific diameter described above.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] Figure 3 is a schematic cross-sectional view showing a decorative body according to a third embodiment of the present invention.

[0054] 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 preferably contains a second resin.

The base material 12B is in contact with the first surface 11Ba of the woven or knitted layer 11B.

[0055] In the decorative body 1B, the woven or knitted layer 11B contains yarn having the specific diameter described above.

[0056] 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.

[0057] 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.

[0058] 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.

[0059] Figure 4 is a schematic cross-sectional view showing a decorative body according to a fourth embodiment of the present invention.

[0060] The decorative body 1C shown in Figure 4 comprises a woven or knitted layer 11C, an intermediate layer 13C, and a base material 12C. The woven or knitted layer 11C preferably contains a second resin. The intermediate layer 13C preferably contains a resin (a third resin). The base material 12C contains a first resin. The intermediate layer 13C and the base material 12C are arranged on the first surface 11Ca side of the woven or knitted layer 11C. The base material 12C is arranged on the surface of the intermediate layer 13C opposite to the woven or knitted layer 11C side. The base material 12C is not in contact with the first surface 11Ca of the woven or knitted layer 11C, but the intermediate layer 13C is in contact with it. The base material 12C is in contact with the surface of the intermediate layer 13C opposite to the woven or knitted layer 11C side.

[0061] In the decorative body 1C, the woven or knitted layer 11C contains yarn having the specific diameter described above.

[0062] As shown in Figure 4, another layer (intermediate layer) may be placed between the woven or knitted layer and the base material. The other layer (intermediate layer) may contain a resin (third resin).

[0063] Figure 7 is an image of a decorative body according to the fourth embodiment of the present invention.

[0064] In the decorative body shown in Figure 7, 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 7, 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.

[0065] 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.

[0066] (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.

[0067] In this specification, "textile" means a fabric woven in which warp threads and weft threads intersect at any angle.

[0068] In this specification, "knitted fabric" means a fabric formed by creating loops with a single thread and connecting these loops.

[0069] 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.

[0070] 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.

[0071] The woven or knitted layer may include, for example, a second resin, paper, metal, or rush grass. The woven or knitted layer may include, for example, a yarn containing a second resin, paper yarn, metal yarn, or rush grass yarn. 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 rush grass yarn may be artificial rush grass yarn, resin rush grass yarn, and more preferably artificial rush grass yarn and resin rush grass yarn. In particular, it is preferable that the weft yarn of the woven layer is the rush grass yarn.

[0072] From the viewpoint of further improving the moldability of the decorative body, further improving the adhesion between the woven or knitted layer and the substrate, and further improving the abrasion resistance of the decorative body, it is preferable that the woven or knitted layer contains a second resin. The type of the second resin is not particularly limited. From the viewpoint of further improving the moldability of the decorative body and further improving the adhesion between the woven or knitted layer and the substrate, it is preferable that the second resin contained in the woven or knitted layer is a thermoplastic resin. In the following description, "the second resin contained in the woven or knitted layer" refers to the case where the woven or knitted layer contains a second resin.

[0073] Examples of the second resin (type of second resin) contained in the woven or knitted fabric layer include polyolefin resin (type 1), ABS resin (acrylonitrile butadiene styrene resin) (type 2), polycarbonate resin (type 3), polyvinyl chloride resin (type 4), and polyurethane resin (type 5).

[0074] From the viewpoint of further improving the moldability of the decorative body and further improving the adhesion between the woven or knitted layer and the substrate, the second resin contained in the woven or knitted layer is preferably a polyolefin resin, ABS resin, or polycarbonate resin, and more preferably a polyolefin resin. In particular, polyolefin resin is desirable to be recycled. If the second resin contained in the woven or knitted layer is a polyolefin resin, the recyclability of the decorative body can be further improved.

[0075] Examples of the polyolefin resins mentioned above include polypropylene resin, polyethylene resin, and polybutene resin. Copolymers of these resins (such as polypropylene-polyethylene resin) are also examples of polyolefin resins. The second resin contained in the woven or knitted layer is preferably polypropylene resin, polyethylene resin, or polypropylene-polyethylene resin, more preferably polypropylene resin or polypropylene-polyethylene resin, and even more preferably polypropylene resin. In this case, the moldability of the decorative body can be further improved, and the adhesion between the woven or knitted layer and the substrate can be further improved.

[0076] The melt flow rate (MFR) of the second resin contained in the woven or knitted layer is preferably 0.1 g / 10 min or more, more preferably 0.5 g / 10 min or more, even more preferably 3 g / 10 min or more, preferably 100 g / 10 min or less, more preferably 50 g / 10 min or less, and even more preferably 30 g / 10 min or less. When the melt flow rate of the second resin is above the lower limit and below the upper limit, the decorated body can be manufactured even more easily.

[0077] The melt flow rate of the second resin contained in the woven or knitted layer is measured in accordance with ISO 1133 under conditions of 220°C and 10 kg.

[0078] The melting point of the second resin contained in the woven or knitted layer is preferably 95°C or higher, more preferably 110°C or higher, even more preferably 130°C or higher, preferably 175°C or lower, more preferably 170°C or lower, and even more preferably 165°C or lower. If the melting point of the second resin is above the lower limit and below the upper limit, the decorated body can be manufactured even more easily.

[0079] If the second resin is a polymer, the melting point of the second resin can be adjusted by the degree of polymerization, etc.

[0080] 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.

[0081] 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 having a diameter of 500 μm or more is yarn containing the second resin. From the viewpoint of 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 having warp threads and weft threads. 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 weft threads containing the second resin, and it is more preferable that it 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 yarn having a diameter of 500 μm or more is weft thread containing the second resin.

[0082] From the viewpoint of 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 having warp threads and weft threads.

[0083] The woven or knitted layer preferably has yarn, and the yarn in the woven layer preferably includes warp threads and weft threads.

In particular, it is preferable that the weft thread is formed from a single fiber and that the diameter of the weft thread is above the lower limit and below the upper limit.

[0097] In the above-mentioned fabric layer, when the warp threads and weft threads are woven together, the lengths of the 100 randomly selected threads will include the lengths of the warp threads and the weft threads in proportion to their respective proportions.

This molded body was supplied to a heating member having a circular cross-section void with a diameter of 0.5 mm heated to 300°C and passed through the void at a speed of 65 m / min to obtain artificial rush (thread diameter: 0.5 mm).

[0155] The same polypropylene spun yarn (English cotton count 24s) as the woven layer (A1) was obtained.

[0156] 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 2 mm and a weft count of 180 threads / 10 cm to obtain a woven layer (A2) with a thickness of approximately 1.3 mm (thickness 1.3 mm, weft diameter 500 μm, surface pattern of the second surface opposite the first surface: tatami pattern).

[0157] (Woven or Knitted Layer) A woven layer (A3) with a weft diameter of 2000 μm was obtained. The same polypropylene resin film (thickness 100 μm) as the woven layer (A1) was obtained. The obtained polypropylene resin film was supplied to a hot plate type uniaxial stretching apparatus set to 120°C and stretched to 2.5 times its original length to obtain a tape-like body (thickness 40 μm). The obtained tape-like body was folded in the uniaxial stretching direction and passed through a through hole with a diameter of 4.0 mm to form a string-like shape to obtain a molded body. This molded body was supplied to a heating member having a circular cross-section void with a diameter of 2.0 mm heated to 300°C and passed through the void at a speed of 65 m / min to obtain artificial rush (thread diameter: 2.0 mm).

[0158] The same polypropylene spun yarn (English cotton count 24s) as the woven layer (A1) was obtained.

The fibers were then stretched and cut using a stretcher to produce polypropylene fibers (single fiber fineness 1.3 dtex, fiber length 38 mm).

[0162] The obtained polypropylene fibers were subjected to a blending and batting 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, using two of the obtained roving yarns, a ring spinning machine equipped with a compact spinning system was used to apply a 40x draft, and the fibers were converged by drawing air in the direction of the roving's movement. After that, the yarn was twisted with a twist coefficient of 3.6 to produce polypropylene spun yarn (English cotton count 40s).
