且纖維的雄、集度也南。結果就疋，能使基布2的纖維之比^面積 相對於以往的不織布來說增加。例如，以以往的紡黏法製作的不 .織布其纖維直徑一般為20μπι左右，但本實施形態的不織布能以 ❹ΙΟμηι左右的纖維直徑製作。其原因考以後述方式，把從喷嘴擠出 的纖維再用後續步驟加以延伸。若纖維直徑在2〇jUm的情況下與 纖維直徑在ΙΟμπι的情況下之每單位長度纖維重量相同，直徑” 2〇μπι的纖維1根相當於直徑10μιη的纖維4根。但是，因表^面積 與周長成比例，所以變成纖維直徑在l〇pm的情況下具有纖維直 徑在20,情況下的2倍表面積。因為電解電鍍是透過化學反應， 在與電鍍液接觸的被鍍物形成金屬的技術，所以金屬是在各纖^ 的表面形成。因此，所形成的金屬之體積與表面積，並非依賴於 基布，表面積，而是構成基布2的纖維之總表面積。故，在本實 施形態的基布2中能使更多金屬附著於纖維層。 ❹[0020] 又，在依照本實施形態的不織布中，因為纖維互相約為平行 的呈直線狀重疊，纏絡少，纖維在纖維排列層的表面以密集的狀 態露出。雖然因為電鍍液會滲透入基布的内部，金屬也會在基布 的内部形成，但是最容易附著金屬的還是纖維排列層的表面與附 近丨然後，在本實施形態中，因為基布表面的纖維之接液面積有 所增加’所以金屬的附著效率增大。換言之，相對於以往的基布 需要從基布表面朝厚度方向將金屬附著到相當的深度，本實施形 態j基布在表面的附著效率高，即使將金屬以比以往更淺的深度 ，著也能得到充分的附著量。其結果，就是促進片材的薄片化盥 輕量化。 200942152 [0021] 本實施形態的基布由延伸的方式形成，原本就比以 ί 2布纖薄(厚度小）。故，完成的片材比起以往更薄。又，由於

Description of the invention: [Technical field to which the invention pertains] [0001] [Prior Art] [0002] In the case of the transfer in Xuxiang, it is still private (4)_. For example, on the small electronic communication device, the noise and malfunction caused by the electromagnetic waves emitted by the electric power line and the factory (10) power line are used for high performance. In the field of the automobile, there is a lot of electronic equipment. Because of the health awareness in recent years, or the suppression of the influence of the electronic parts that have become heavy, there are many devices in the factory. Concerns about the users of the device and the patients with electromagnetic allergies, the demand for electromagnetic wave shielding is increasing in the home and in the hospital. Hospital [0003] ❿ These electromagnetic wave shields are often used for the plating of metal fibers, non-woven fabrics, etc. (10). For example, refer to Japanese _ 2_韵877号号 2 [Summary of the Invention] [0004] The more the electromagnetic wave shielding characteristics of the gold ladder L 附着 attached to the substrate by the electric ore step, the higher the electromagnetic shielding property is. However, the material. The fiber is thick and straight and becomes a high-strength polymer fiber of the general spunbonded nonwoven fabric, and its surface area is limited by the diameter ϋ 200942152 * Generally, the electroless plating of the sheet for electromagnetic wave shielding, 2 = de-energizing Shot, because the metal is in the wetted part of the beak and the plating solution (the wind, the surface area of the right fiber is small, and the amount of metal adhesion is also relatively small. The right increase in the amount of adhesion increases the film thickness of the substrate. Because the penetration of the electro-hydraulic liquid is limited, the result becomes insufficient to allow the plating solution to penetrate into the inside of the substrate, only the weight of the area (the weight of the unit surface) and the thickness of the substrate. However, electromagnetic wave shielding is strongly required depending on the application. In the lightweight, the case of the two movements, the density of the parts has reached the limit, and it is also required to be more ambiguous. It must be avoided to avoid the substrate that does not contribute to the electromagnetic wave shielding function. In terms of electromagnetic shielding for parts, it is also lightweight, and it is desirable that the substrate be as thin as possible. In view of the above problems, the aim is to provide various kinds of i-uses for lightweight, thin-film and metal-shielding effects. Providing electromagnetic waves using the sheet [0007] The layer is composed of a sheet comprising a base fabric comprising a base fabric comprising at least one strand and at least one side of the base fabric extending linearly. i no: ί = the direction of the soap is about linear, - the side of the (four) with rft. The length of the fiber is extended, the diameter of the fiber is tightened, and the specific surface area of the fiber (the surface area per unit volume is quite dependent) The specific surface area of the fiber n is = the ratio of the surface area of the metal to the raw surface, and the direction of the fiber used in the vicinity of the surface of the base fabric is (4) Λ 录 录 录 站 u u 由 由 由 由 连续 连续 连续 连续 连续 连续 连续 连续 连续The fiber filling efficiency is improved, and it is possible to make a slim = ίίί, extending the fiber to the inside of the sheet and extending neatly, 200942152 K in the ίΐί full and the metal adhesion efficiency becomes higher, the advantage of "slice", 'with rotten The slimness characteristics complement each other, and there are also [0009] the base fabric contains a plurality of layers of fiber alignment layers, and the inter-dimensional alignment layers are stacked in such a manner that the length directions of the long fibers are different from each other... ❹ Magnetic wave shielding sheets, wallpapers, electricity [ 0011] According to the present invention, it is possible to provide a light-weight, thin-brown type of use---the present invention is to use an electromagnetic wave screen of the present invention. [Embodiment] [0014] An embodiment of a sheet of the invention of the present invention is shown in FIG. :== Fig. The sheet 1 comprises a base fabric composed of a non-woven fabric, which is referred to as a _table_metal, but a singularity, and is called a layer in the form of a layer. The plating portion 3a 3b/ ΓElectrical diagram base cloth 2 is formed on both sides, only on any one-sided surface ^ can make 3a,% _ electric micro-thief wire, Z make: fruit 'steel is mainly responsible for electromagnetic wave shielding effect, recorded the main [0015] The adjustment is adjusted by changing the time during which the base cloth 2 is immersed in the plating solution. The base cloth is immersed in the electric ore liquid for a short time, and the metal adhesion amount which is not the original gas permeability of the 200942152 cloth can be obtained. If it is immersed for a longer period of time, the amount of metal attached can be such that the plating portions attached to the respective fibers are connected to each other. 2 is an exploded perspective view of the base fabric. The base fabric 2 is composed of a plurality of layers of fiber alignment layers in which a plurality of continuous long fibers are arranged in a straight line extending in a single direction. Although four fiber array layers 12A, 12B, 12C, and 12D are shown in the drawing, the number of stacks can be appropriately determined, and it is not necessary to have only one sheet depending on the application, which will be described later. The fiber array layers 12A, 12B, 12C, and 12D are thermocompression bonded to each other to form a base fabric φ [〇〇17] Fig. 3 is a partial perspective view showing an enlarged portion of the fiber array layer of the base fabric. Although only the fiber alignment layers 12A and 12B are shown in the figure, the other fiber layers are also of the same structure. As shown in the figure, the fiber contact 12A is an aggregate of a plurality of fibers 13A which are flat and linearly extended. Similarly, the fiber arranging layer 12B is a collection of a plurality of scales 13B extending linearly from each other. There are also cases where the fibers 1 =, 13B are stacked on the two sides of the towel. It is made of a thermoplastic resin such as polypropylene ray, polyester, polyester, polyamide, polystyrene resin, or a modified resin. It is also possible to make the acrylonitrile-based resin or the like related to the wet or dry spinning method = the fiber extending direction of the fiber layer is 15 Β Β 昼 定 定 定 定 定 相邻 相邻 相邻 相邻 相邻 相邻 相邻 相邻 相邻 相邻 相邻 相邻 相邻 相邻 相邻 相邻 相邻 相邻 维 维 维 维 维 维 维: Two or more sheets of fibers may be continuously: Column layer: same: extension::: [0018] 200942152 The basis weight of the base fabric is preferably 5 g/m 2 or more and 60 g/m 2 or less. It is also possible to provide adhesive tape, adhesive material, etc. on one or both sides of the base fabric. [0019] * The fibers 13a, 13B, 13C, 13D of the respective fiber arrays Zhan 12A, 12B, 12C, and 12D are arranged to extend in the extending directions 15A, 15B, 15C, and 15D. Therefore, the linearity and the directivity of the fiber are extremely higher than those of the nonwoven fabric produced by the conventional melt blow method, and the maleness and the degree of the fiber are also south. As a result, the ratio of the fiber area of the base fabric 2 can be increased with respect to the conventional nonwoven fabric. For example, the nonwoven fabric produced by the conventional spunbonding method generally has a fiber diameter of about 20 μm, but the nonwoven fabric of the present embodiment can be produced with a fiber diameter of about ημηι. The reason for this is to extend the fiber extruded from the nozzle in a subsequent step. If the fiber diameter is 2〇jUm and the fiber weight per unit length is the same as the fiber diameter in the case of ΙΟμπι, the fiber of the diameter "2〇μπι corresponds to 4 fibers of 10 μm diameter. However, due to the area of the surface It is proportional to the circumference, so it has a fiber diameter of 1 pm and has a fiber diameter of 20, which is 2 times the surface area. Since electrolytic plating is a technique of forming a metal by a chemical reaction and a plated material in contact with a plating solution, Therefore, the metal is formed on the surface of each fiber. Therefore, the volume and surface area of the formed metal do not depend on the base cloth and the surface area, but the total surface area of the fibers constituting the base fabric 2. Therefore, the base of the present embodiment is In the cloth 2, more metal can be attached to the fiber layer. [0020] Further, in the nonwoven fabric according to the present embodiment, since the fibers are linearly overlapped with each other in parallel, the entanglement is small, and the fibers are arranged in the fiber arranging layer. The surface is exposed in a dense state. Although the plating solution penetrates into the interior of the base fabric, the metal is formed inside the base fabric, but the metal is most likely to adhere. Then, in the present embodiment, since the liquid contact area of the fibers on the surface of the base fabric is increased, the adhesion efficiency of the metal is increased. In other words, the base fabric is required from the conventional base fabric. The surface of the present invention has a high adhesion efficiency on the surface of the base fabric in the thickness direction, and a sufficient adhesion amount can be obtained even if the metal has a shallower depth than the conventional one. The sheet is lightened and lightened. 200942152 [0021] The base fabric of the present embodiment is formed by an extension method, which is thinner than the ί 2 cloth (thickness is small). Therefore, the finished sheet is thinner than before. Moreover, since the fiber f degree improves the penetration efficiency of the electric clock liquid, the metal adhesion efficiency is also more tangled into a thinner and lighter weight. This is an important advantage for small phones and the like. Moreover, this is also related to the ease of handling such as manifolding, transportation, etc. Generally, in the case where the weight per unit area is about 3 Gg/m2 in the -pass, the thickness is left, but the base fabric of the present embodiment The weight per unit area is less than the thickness of the ΙΟΟμηι. [0022], secret two, the base fabric of this configuration is composed of continuous long fibers, immersed in electric ore in the fiber pile 'from pollution prevention plating It is also advantageous from the viewpoint of the liquid. From the beginning, the base fabric is easy to maintain the initial state even if it is used for a long period of time, and the strength is not easily reduced. [0023] ', 唆屮' The cloth does not actually contain volatility or addition at room temperature, and has a process of volatility or exudation. _--------------------------------------------------------------------------------------- For the purpose of preventing static electricity or reducing the purpose of stretching, it is necessary to use an additive or a auxiliaries containing an oil component. However, in order to improve the adhesion of the metal, it is necessary to The surface of the minerals • The processing aids necessary for each step. For example, 'the previous non-woven fabric, or washed to a clean state. In the present embodiment, the linear shape of the second embodiment 22 is small, and the unevenness of the arrangement is small. When the fiber is stretched, it is not required to carry static electricity. Therefore, the metal is excellent in attachment to the base fabric. [0024] [〇〇25^下下] Description of the use of the above-mentioned sheet material type embodiment 200942152 Overview = ί ^ Use this sheet of 作为 作为 as the electromagnetic wave shielding #材的电话电话42 细神43 and the operation department In addition, the inside of the antenna body 42 in which the source is not generated, and the inner surface of the electromagnetic wave main body 42 is permeable to the magnetic wave shielding sheet by an adhesive or an adhesive tape. 46. Although the pattern (4) is located at the outer side of the electromagnetic wave shielding sheet 46 with the base station ϊΐ 45, it is placed on the outer side of the electromagnetic wave shielding sheet 46. However, the circuit board is located in the electromagnetic wave shielding sheet 46. [0026] 难以 In the difficult telephone 41, the slave antenna The electromagnetic wave released by 47 becomes the internal 'lower weight of the various elements on the thin circuit board 45. The weight increase is also small' and because of the light weight, for the mobile phone [0027] ϋ. The sheet of the present invention is a schematic cross-section of a wallpaper for electromagnetic wave shielding. The wallpaper body 52 and the electromagnetic wave shielding sheet 53 are formed by an adhesive = structure. The surface 51 is such that the electromagnetic wave generated by the connector body 56 and the reinforced concrete wall electrical product with the wallpaper body 52 facing the room is simple or 6 = it can be said that it is difficult to shield even with concrete. Applying the "[25] to the wall of the home or hospital (10) of this embodiment can improve the electromagnetic shielding performance of the wall. It is not only used in concrete walls, but also in the sand (four) wall. In addition, it can also be used for ceilings or floors, and can be pre-installed inside the building. Further, it is also possible to use various types of buildings which can be expected to have an electromagnetic wave shielding effect. A door or a storm belt, the sheet of the present invention is applied as an example of an electromagnetic wave shielding tape for electric wires. Fig. 6A is a conceptual side view, and Fig. 6B is a conceptual cross-sectional view. The electric wire 200942152 61 is composed of a plurality of covered electric wires 62. The covered electric wires 62 are covered by a skin 63 as a whole. The assembly of 62 is filled with a screw-fill material. In the covered electric wire, the electromagnetic wave shielding adhesive 165 is used only in the electromagnetic wave shielding tape 65. The wire is shielded from the electromagnetic generated by the coated Wei 62. The screen of the Wei line 62 can also be effective [0030]. The electromagnetic wave shielding tape 6 used in the present embodiment is perpendicular to each other, and can be produced by a fiber winding direction, and the electromagnetic wave shielding tape 65 of the electric wire is wrapped. The arrow in Fig. 1 indicates that the fiber [0031] is perpendicular: the base fabric in which the fiber alignment layers of the layers are mutually parallel (4) in a manner parallel to each other to form a base fabric. In addition, although in the present embodiment, the structure of the ί " ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί In the case of the domain table, in turn, it is expected that the wire affected by the electromagnetic wave of the g part suppresses the electromagnetic wave transmitted from the outside to the wire, such as the ton of Wei, which is the domain paste of the ton. A method of manufacturing the base fabric 2 will be described. Fig. 7 is a schematic view showing a manufacturing apparatus of the fiber array layer constituting the base fabric. The fiber array apparatus 21 includes the main mold 24 and the conveyor belt 25 to form a weave ==兀22, U and the extension single το 23 of the extension cylinders 26a, 26b and the take-up rolls 27a, 27b. The front end (lower end) of the nozzle mold 24 includes a plurality of nozzles 28 juxtaposed in a straight direction with respect to the paper surface sag 200942152 (only shown in the figure) (3)) The resin is supplied, and the sergeant is pressed from the nozzle 28, and the sergeant is pressed, and the heat is applied to the resin melting point or higher. [Hot air-delivery-office 32a, 32b =, and _ The slits of 32a and 32b are connected, and the extrusion direction of the port fibers 31 is about parallel high-speed airflow. The fiber 31 which can be extruded with the ί", 'f nozzle 28 is maintained in the meltable heart of the draftable 'through the speed of the air force of the force of the pair of embroidery. 3. 僻古古, *々& ^ + hand 4 The blade imparts a draft to the fiber 31 so that the temperature of the fiber 31 is higher than the spinning temperature of _31 by more than or equal to i^c. In the method of forming the fibers 31 into the bristle spray mold 24, the molecular orientation of the fibers 31 can be made small by melting the temperature of the fibers 31 which have just been discharged from the nozzles 28 to a height 31. A conveyor belt 25 is disposed below the movements 24 . The conveyor belt 25 is wound around a conveyor belt roller 29 or other parent that is rotated by a drive, (not shown), and is driven by the rotation of the nail roller 29 to drive the conveyor belt 25 to be extruded from the nozzle 28. j is transported in the right direction of the schema. [0034] The fiber 31 flows along a high-speed airflow which is ejected from the slits 33a, 33b on both sides of the nozzle 28. The high-speed airflow is converged by the 'high' pressure of the slits 33a, 33b, and flows in a direction approximately perpendicular to the conveying surface of the conveyor belt 25. In ancient times, a spray nozzle 35 is provided between the nozzle mold 24 and the conveyor belt 25. The spray nozzle 35 is an appliance that ejects misty water droplets toward the airflow, thereby cooling the fibers 31 and rapidly solidifying. = Actually, a plurality of spray nozzles 35 are actually provided, but only one is shown in FIG. The fluid ejected from the spray ^ 35 may be any one that can cool the fiber 31. It is not necessarily required to have water or the like, and may be cold air. [0036] In the vicinity of the squirting die 24, a region where the high-speed airflow is generated by the slits 33a, 33b attacks the airflow vibrating mechanism 34 having a cylindrical shape. The air stream vibrating mechanism 34 is parallel to the shaft 34a 11 200942152 •==straight axis 1:^=the upper fiber (4). In general, the width of the gas _ aligning layer is about the time when the jet clock is at the tread wall. The gas vibration mechanism 34 uses the Coanda effect to change the fibers 31 L,, *, ', and the Coanda effect. In other words, the long axis of the elliptical shape of the air stream vibrating mechanism 34 is high &=. In the case of Fig. 5, the fiber 31 is oriented toward the conveyor belt 25; the upper and lower structures 34 are wound around the 34a spine 90-, and the nickname, & When the airflow vibrator-speed airflow direction is vertical, the fiber \ toward the input ^ 2 = 4 = circle, the long axis is offset from the high ,, and the offset reaches the maximum at this time. If the gas, the direction d (the right side in the figure): the moving fiber r to the conveyor belt 25 of the seven, the condensation _ dimension 31 in the vertical direction, i5 dimension up, the surface (four) has - material (four) Qian Wei fine, [0037 The U-belt 25 is provided with the draping fiber 31, and is transported by the extension cylinder that has been extended to the extension cylinder 26b. Thereafter, the fiber 31 is moved to the extension cylinder ❹ 5i: i73f; the sticker 1 is attached to the two extensions W6a, -. 'For the part to convey in the longitudinal direction'_31 into a mesh. In the case of a strong heart-shaped heart, the adjacent fibers 31 are spliced together with each other [0038] attached to the extension cylinder, and the mesh obtained by the same rotation, and then the extension of the cylinder Moved, so the mesh is oriented in the vertical direction i: square extension: ΐ dimension array 38. Thus, by arranging the spun mesh, the alignment of the filaments can be further increased. Since the fiber 31 is filled with the fiber 31 having a small tensile stress and a large elongation. This is achieved by the above-mentioned > 3 k spray sound 35 ejecting a mist-like water droplet 'the high-speed air stream containing a misty 12 200942152 liquid. The fiber alignment layer formed by the above method is concentrated in one direction. The direction of the fibers will be toward the additive or jade auxiliary in the steps of producing the fiber alignment layer as described above. Specifically, in the case where the fiber 31 = (spinning), the (four) contains the oil age of the addition_addition: the stomach sputum on the conveyor belt 25, the fiber stretching step, the agent or processing aid. Therefore, after 4% of the fiber alignment layer = additive or processing aid. [0041] The fiber alignment layers thus produced are stacked in the fiber direction and thermocompression bonded to reduce the cloth 2 described above.
