Record: An example of a laminated product is as follows. In addition, there are a variety of diversified products in addition to the laminated products. ', the following example (1) is a laminated board of a substrate of a printed wiring board: the laminated board is, for example, a paper which is composed of kraft paper and a resin, or a glass which is difficult to be composed of glass fiber woven fabric and epoxy Oxygen layer (2) Printed wiring board: The printed wiring board is a single-sided printed wiring board in which a conductor pattern is formed on one surface of a substrate, a double-sided printed wiring board in which a conductor pattern is formed on both sides of the substrate, and not only the outer surface of the substrate (4) A multilayer printed wiring board or the like in which a conductor pattern is also formed. (3) The display is not good. For example, liquid crystal display, electric excitation light, etc. (4) Semiconductor package: a chip size package (CSP) or the like having substantially the same size as a wafer. The 098123601 3 201008774 step of manufacturing the various laminated products (formed bodies) by the forming press device is to interpose a cushioning material between the hot plate and the laminated product. The heat-dissipating disk and the laminated product are not in direct contact with each other, and have a viscous button, and can exert a comprehensive function of transferring the heat generated by the hot plate to the laminated product. A specific use example of the cushioning material will be described with reference to Fig. 1 . Fig. i is a view showing a forming press of a laminated board in a manufacturing apparatus for a double-sided printed wiring board. The molding press apparatus i shown in Fig. 1 is used in a pair of cushioning materials c disposed on the inner side of the hot plate 40 and on the inner side of the cushioning material C. The mirror panel 5G, the steel (four), and the prepreg 70 and the copper box 60 are formed into a double-sided printed wiring board. The pre-diffuser sheet 70 is formed by laminating a plurality of sheets in which a glass fiber cloth is impregnated with an epoxy resin q semi-hard state. The laminate is formed by applying heat and pressure to the hot plates 40 and 40, and the molding conditions at this time vary depending on the formulation of the epoxy resin material. Therefore, it is necessary to cause the heat transfer amount (heating rate: C/min) of the inspection material G to be caused by the forming press step. It is assumed that the amount of thermal movement of the cushioning material C is not consistent with the forming condition of the epoxy resin. The laminated product may cause poor physical properties. For example, a laminated product which is located very close to the hot plate 4〇, 4〇, and a laminated product located at a central position between the hot plates 4〇 and 4〇 and away from the hot plate 4G may have poor physical properties. Moreover, even in the same laminated product, there may be a difference in physical properties between the central portion and the peripheral portion. 098123601 201008774. The reason is that the resin viscosity in the prepreg 70 is temporarily lowered by the thermocompression bonding, and after the resin is returned to the liquid state, the resin hardening manufacturing step is gradually performed, and in this step, the hot plate 40 is pressed and pressed to rise. The timing of the pressure is offset. That is, the contact between the prepreg sheets 7 and the copper box 60 is performed because the resin is moved, and the gas is removed from the resin. Opportunity to press the wire with pressure: The more acceptable the range. For example, when the resin viscosity becomes too low, what about the prepreg? When pressure is applied to the resin, the resin flows more than necessary, and the thickness of the center portion of the laminated plate is increased, and the thickness of the peripheral portion is reduced. As a result, the thickness of the laminated mouth produced in the end will be uneven.
面’當樹脂黏度變為過高時，若對預浸片70施加 壓力’樹脂便不會充分流動，樹脂中所含的空氣不會消失， 因而積層製品的絕緣性便會發生問題。所以 具有優異升溫速度。 玎何。要求 :習:：’成形壓合時’大多將牛皮紙等使用為緩衝材。 2 it 造積層製品的大型化與精密化演進’因 而渴求具有優異特性的緩衝材。 此種緩衝材係有如：含有無機纖維與耐熱性芳香族 體之紙漿狀者（日本專利特開昭59侧95號公報），以及: 098123601 5 201008774 有芳香族系聚醯胺纖維者（曰本專利特開昭62 i56i〇〇號公 報）。但是，任一緩衝材均頗難維持緩衝性，因而壽命短。 例如此種緩衝材係有如圖6所示成形壓合㈣熱缓衝材 C4。圖.6所示係習知成形壓合用耐熱缓衝材^的剖視圖。 圖6所示緩衝材C4係由：基體UB、積層於基體nB表 面且經針軋的短纖維騎層11A、以及積層於基體ιιβ背面 且經針軋的短纖維氈材層11A構成。 依此，緩衝材C4係積層著2層氈材層lu、nA。氈材層 11A的短纖維係由間位式芳香族聚醯胺構成。基體iib係使 用利用由财熱性纖維構成的經紗UB1與緯紗⑽所形成織 布。 此緩衝材C 4的Μ材層丨丨A因為短纖維係由間位式芳香肩 聚醯胺構成，因而可輕易地調整升溫速度。但是，相反的 位咖胺的短纖維較難維持緩::生侧 衝材C4哥命較短。 所以，為達緩衝材C4緩衝性的維持， 維的面密度。但是，若增加域_面密/考慮增加短· 變慢，導致較難進行升溫速度調整，二’導熱速率便脅 導致使用中_手性惡化。 &鱗（：4會變重， 為解決緩衝材C4的此種缺點，便有 合用耐熱緩衝材C5。圖7所示係其他：7/斤不成形愿 緩衝材C5的剖視圖。 °、形堡合用耐熱 098123601 6 201008774 圖7所示緩衝材C5係由：基體21B、積層於基體21B表 面且經針軋的短纖維氈材層21A、以及積層於基體21B背面 且經針軋的短纖維氈材層21A構成。即，緩衝材⑺係雙層 - 能材層21A、21A積層。 - 氈材層21A的短纖維係由以聚對苯二甲醯對苯二胺等為 主體的對位式芳香族聚醯胺構成。基體2ΐβ係使用具有由财 熱性纖維構成之經紗21Β1與緯紗21Β2的織布。 φ 因為該緩衝材C5的氈材層21Α係短纖維由對位式芳香族 聚醯胺構成，因此緩衝性維持良好。但是，因為緩衝材c5 的導熱率過高，因而缓衝材C5的升溫速度調整較難。為調 整升溫速度，必需增加短纖維的面密度，但因為緩衝材邙 會變重’因而使用中的順手性變差。 美國專利US5, 945, 358號公報揭示有：為獲得良好空隙容 積（空隙、多孔性）、游走安定性、以及耐磨損性，而配置紡 ❹黏不織布的抄紙祕。該抄紙用耗為能將纺黏不織布固定於 抄紙用鼓上，便構成棉氈纖維朝氈厚度方向配置。 然而，該抄紙用氈係游走並對濕紙施加壓而使用，並非利 用熱盤等施行加熱使用。 t ，戶斤以’對該抄紙用數並不要求耐熱性、升溫速度調整及緩 衝性維持等特性。所以，美國專利腿，9奶，·號公報並未 有相關本發明作用效果的該等特性之記載。 [專利文獻1]日本專利特開昭59]92795號公報 098123601 7 201008774 [專利文獻2]日本專利特開昭62-156100號公報 [專利文獻3]美國專利US5, 945, 358號公報 本發明係為解決此種課題而完成，目的在於提供升溫速度 的調整容易、緩衝性維持優異的成形壓合用耐熱緩衝材。 【發明内容】 為達成上述目的，本發明係為利用成形壓合裝置進行積声 製品（被成形體）製造而使用，由基體與氈材層積層的成形^ 合用耐熱緩衝材。該緩衝材係對上述基體其中一面與另一 面’分別各至少設^層（即！層或2層以上）含耐熱性短纖 維（staple fiber)的歸層。在上述緩衝材内部，由細纖度 短纖維構成的複數起毛纖維體係貫通上述基體，且形成於2 述緩衝材厚度方向並將所有的上述氈材層相連結。7 、上 藉此’便可獲得具有緩衝性，且升溫速度的調整 可將熱均等地傳遞給積層製品全' 耐熱緩衝材。 《特性成形壓合用 各耐熱性短纖維的氈材層」係將 纖維進彳+、、θ娃# # ι、、r玍短纖維與其他短 纖维進仃4構成，且耐熱性短纖維含 η。 v 重量％以 織維’係含有從間位式_ 擇！種或聚齡及卩枝纖_構成群組中選 形成。起毛纖維 起毛纖維體係利用針軋施行纖維間交織而 098123601 201008774 體係由纖度1.0 10. 〇dtex(丹尼）、耐熱性短纖維構成。此 情況，起毛纖維體的纖度較佳1. 0〜6.

Therefore, it has an excellent heating rate. Anyway. Requirements: Xi:: When forming pressure is used, kraft paper or the like is often used as a cushioning material. 2 It is a large-scale and sophisticated evolution of building products, so it is eager for cushioning materials with excellent characteristics. Such a cushioning material is, for example, a pulp containing inorganic fibers and a heat-resistant aromatic body (Japanese Patent Laid-Open No. 59-No. 95), and: 098123601 5 201008774 Aromatic polyamide fibers (曰本Patent Special Opening 62 i56i 公报 Bulletin). However, it is difficult to maintain cushioning properties of any of the cushioning materials, and thus the life is short. For example, such a cushioning material is formed by press-fitting (four) thermal cushioning material C4 as shown in Fig. 6. Fig. 6 is a cross-sectional view showing a conventional heat-resistant cushioning material for forming press-bonding. The cushioning material C4 shown in Fig. 6 is composed of a base UB, a short fiber riding layer 11A laminated on the surface of the base nB, and a needle-rolled short fiber felt layer 11A laminated on the back surface of the base ιι. Accordingly, the cushioning material C4 is laminated with two layers of felt layers lu and nA. The short fiber of the felt layer 11A is composed of meta-type aromatic polyamine. The base body iib uses a woven fabric formed by a warp yarn UB1 composed of a heat-generating fiber and a weft yarn (10). The coffin layer 丨丨A of the cushioning material C 4 can be easily adjusted in temperature because the short fiber system is composed of meta-fragrance styrofoam. However, the opposite bite of short-acting bitcoamine is more difficult to maintain: the raw side punch C4 has a shorter life. Therefore, in order to maintain the cushioning property of the cushioning material C4, the dimensional density of the dimension. However, if the increase of the domain_face density/consideration is shortened and slowed down, it is difficult to adjust the temperature rise rate, and the second heat transfer rate is threatened to cause deterioration in the use. & scale (: 4 will become heavier, in order to solve such a shortcoming of the cushioning material C4, there is a combination of the heat-resistant cushioning material C5. Fig. 7 is another sectional view: 7 / kg not forming the cushioning material C5. °, shape Fortress heat resisting 098123601 6 201008774 The cushioning material C5 shown in Fig. 7 is composed of a base 21B, a short-fiber felt layer 21A laminated on the surface of the base 21B and needle-rolled, and a staple fiber felt laminated on the back surface of the base 21B and needle-rolled. The material layer 21A is formed. That is, the cushioning material (7) is a double layer - the energy layer 21A, 21A is laminated. - The short fiber of the felt layer 21A is an alignment type mainly composed of polyparaphenylene terephthalate or phenylenediamine. The base 2 ΐβ is a woven fabric having a warp yarn 21Β1 and a weft yarn 21Β2 composed of a heat-generating fiber. φ Because the cushion material C2 of the cushioning material C5 is made of a para-type aromatic polyamine Since the cushioning property is maintained, the cushioning property is maintained high. However, since the thermal conductivity of the cushioning material c5 is too high, it is difficult to adjust the temperature rise rate of the cushioning material C5. In order to adjust the temperature increase rate, it is necessary to increase the areal density of the short fibers, but the cushioning material 邙Will become heavy' and thus easy to use U.S. Patent No. 5,945,358, the disclosure of which is incorporated herein by reference to U.S. Patent No. 5, 945, 358, the disclosure of which is incorporated herein by reference. It is possible to fix the spunbonded nonwoven fabric to the papermaking drum, and the cotton felt fibers are arranged in the thickness direction of the felt. However, the papermaking felt is used to move away from the felt and apply pressure to the wet paper, and is not heated by a hot plate or the like. The use of t is not required for the papermaking number, such as heat resistance, temperature increase rate adjustment, and cushioning maintenance. Therefore, the U.S. Patent Leg, 9 Milk, No. Bulletin does not have the effect of the present invention. [Patent Document 1] Japanese Patent Laid-Open No. 59, No. 92,995, No. 098,123, 601, and Japanese Patent Publication No. JP-A-62-156100 [Patent Document 3] US Patent No. 5, 945, The present invention has been made to solve such a problem, and an object of the invention is to provide a heat-resistant cushioning material for forming press-bonding which is easy to adjust the temperature-increasing rate and excellent in cushioning property. In view of the above, the present invention is a heat-resistant cushioning material for forming a laminate of a base material and a felt material by using a molding press device to produce a sound-sounding product (molded body). The cushioning material is applied to one side of the base body. On the other side, at least each layer (ie, a layer or two or more layers) is provided with a layer of heat-resistant staple fibers. Inside the cushioning material, a plurality of raised fiber systems composed of short fibers of fine denier penetrate the above-mentioned The base body is formed in the thickness direction of the cushioning material and connects all of the above-mentioned felt layers. 7. By this, the cushioning property can be obtained, and the temperature increase rate can be adjusted to uniformly transfer the heat to the laminated product. ' Heat resistant cushioning material. The "felt layer of each heat-resistant short fiber for characteristic molding and press-bonding" is composed of a fiber 彳+, a θ # #, a r 玍 short fiber and another short fiber 仃 4, and the heat-resistant short fiber contains η. v % by weight in the weaving dimension of the system containing the _ choice! Species or ages and lychee fibers are selected from the group. Raising fiber The fleece fiber system is intertwined by interlacing with needle rolling. 098123601 The 201008774 system consists of a fineness of 1.0 10. 〇dtex (Danny) and heat-resistant short fibers. In this case, the fineness of the raised fiber body is preferably 1. 0~6. Odtex (better 1. 0~3. Odtex). The density of the cushioning material is preferably G.3g/cm^G 5g/cm3.1, preferably by laminating the surface layer on the surface of the punching material. The surface layer is joined to the cushioning material by means of joining means (e.g., resin, prepreg, bonded short fibers, etc.). The raised fibers are the fibers that are oriented in the direction of the thickness of the cushioning material. "Flocking fiber body" means that at least three of the above-mentioned raised fibers are bundled. The bundled raised fiber body is preferably disposed in a plan view from the buffer material per unit area (w) to 束5 bundles (i.e., 5 bundles/cro2). Further, the upper limit of the number of bundles of the batt fibers of the cushioning material may be in a plan view of the cushioning material, and almost or all of the unit area may be occupied by the bundle of raised fibers. The aspect of the above-mentioned raised fiber body can be confirmed by a microscope (refer to Fig. 4). In the direction of the thickness of the cushioning material, the domain of the cushioning material is aligned with the base of the cushioning material toward the substantially vertical side 6+D7. In the present invention, the short fiber axis of the raised fiber is a buffer material that is aligned in the range of 45 degrees to 135 筌 in the range of the base degree and 225 degrees to the = surface area, respectively. And culvert 3 is formed in the structure of the buffer material in the thickness direction. In addition, as shown in FIG. 2 and FIG. 3 which will be described later, it is easy to adjust the temperature rise rate of the heat-resistant cushioning material for forming press-bonding in the x direction (10) extending in the warp direction and the weft yarn, 098123601 9 201008774, And the cushioning property is maintained excellent. [Embodiment] The basic structure of the heat-resistant cushioning material for press-forming of the present invention is a cushioning material used in the production of a laminated product by a molding press, and a layer is laminated between the substrate and the drum layer. The cushioning material is provided with at least an i-layer (i.e., i-layer or two-layer or more), respectively, with respect to the surface (surface) and the other surface (back surface) of the substrate. Inside the cushioning material, a plurality of raised fiber systems, which are composed of short fine fibers, are formed through the substrate 1 in the thickness direction of the cushioning material and connect all the felt layers. In particular, it is preferable that the cushioning material is a cushioning material, and the contact resistance of the nucleus layer is preferably a meta-type aromatic polyamine ((10) 渺, trade name / Teijin Co., Ltd.; coffee 18, trade name / One or more selected from the group consisting of DuPont Co., Ltd., the para-type aromatic polyamines CAR8, the trade name/DuPont company; the Twar〇n, the trade name/the Teijin shares, and the fire-resistant fiber. Kind. For example, the sacrificial layer may be composed of a short fiber composed of a meta-type aromatic polyamine and a complex short-term mixture of a para-type aromatic amine, and a buffer is used for the buffer material. When the laminated product is produced by the forming press-fitting device, the thermal buffer material is combined with the secret pressure layer of the base layer and the layered layer. The buffer material is a material layer of a short fiber containing a meta-type aromatic polyamine, and another dragon layer of a short fiber containing a para-type aromatic polyamide, respectively. (surface) and the other side (back) 098123601 201008774 Each has at least 1 layer (ie 1 or more layers). In the inside of the cushioning material, a plurality of raised fiber systems composed of short fibers having a fine fineness penetrate the above-mentioned money, and the above-mentioned slow riding thickness is formed and all the layers of the cooked material are joined. • The preferred hair raising fiber system in the cushioning material is formed by using a heat-resistant short fiber having a fineness of 1·〇 to 6.0 dtex (Danny) and performing fiber-bonding by needle rolling. More preferably, the buffer material density is 03g/cm3i 05g/cm3. • s is a weak interfiber interweaving between fat and short fibers, making it difficult to form high-density hair fibers. Correction, the book is rich, the fluffing fiber system has fineness: degree heat-resistant short fiber. Namely, a fine-density heat-resistant residual fiber is produced, and a high-density raised fiber body is formed by interlacing fibers between needles. Therefore, the majority of the nucleus _ dimension consists of a lot of fluffy in the cushion: phase:: the above-mentioned matrix, and formed in the thickness direction of the cushioning material and all the punching materials are strict, / ° according to this, the density is mostly hairy fiber body It can be used for slow temperature rise (4), and cushioning _ sex buckle. Kawasaki can (4) carry out the upper body in the case of feeding the wire, and when using the thickness of the Bersaki (4), the hair raising _Wei will play the elastic speed of the cushioning material. The fine-fibre staple fiber and the raised fiber body do not penetrate the 098,123,601 degree direction and the thermal conductivity deteriorates. The buffer material base of the team is so thicker than the cushioning material. If the density of the cushioning material is 〇3g/cml〇.5g/cm3, the cushioning material elasticity is improved due to the high density 201008774, and the cushioning property of the fiber is multiplied. The role of the cushioning. The force is preferably laminated on the surface of the cushioning material. According to this, when the composite product (formed body) is pressed and pressed, the surface of the surface material undergoes follow-up deformation in accordance with the shape of the uneven surface. As a result, since the surface layer is in close contact with the laminated product, the cushioning material can easily adhere to the uneven surface of the laminated product. Therefore, the hot plate can transmit a heat-resistant resin having a mold release property, preferably a cover film or a metal bond, or a hot plate, to the laminate. For the film, the layer film may be a thin resin or a polystyrene resin which is a composite film for press-forming, and a polyolefin resin may be used. Further, as the cover film, a paper made of a fiber mainly composed of poly-m-phenylm-xylyleneamine can be used, such as Ν0ΜΕΧ® (trade name/made by DuPont) paper. As the metal foil, for example, an aluminum alloy foil, a stainless steel foil, or the like can be used. The heat resistant resin may be derived from tetrafluoroethylene/ethylene copolymer (ETFE), tetrafluoroethylene/perfluoroalkyl vinyl ether copolymer (10), tetrafluoroethylene/hexafluoroethylene dilute copolymer (FEP), and polytetrafluoroethylene. Selected from the group consisting of ethylene (PTFE). Further, in order to laminate (dispose) the surface layer on the surface of the cushioning material, a resin, a prepreg or a bonding fiber is used. As the resin, an epoxy resin or a polyimide resin can be used, and a heat-fusible resin such as a film can be used. For the prepreg, a pre-weave epoxy 119123601 12 201008774 or the like can be used. For the bonded fiber system, for example, unextended COSEX® fiber, wholly aromatic polyester fiber (trade name: VECTRAN®) can be used. Next, an embodiment of the present invention will be described with reference to Figs. 1 to 5 . 2 is a cross-sectional view of a heat-resistant cushioning material for forming press-bonding according to an embodiment of the present invention. FIG. 3 is a cross-sectional view showing a heat-resistant cushioning material for forming press-bonding according to another embodiment. Fig. 2, the cushioning material 1G is composed of: the base (10) is the middle side (the fourth (four) (four)) surface (the (four) cut layer ία laminated on the other side of the base suspension 10B (back side) 2, the third felt layer 1C on the surface of the first felt layer 1A, and the fourth layer 11} on the surface of the first layer 2 layer, and the second layer U and the layer _ layer (10) The surface of the body (10) and the back surface are used. The third layer is 1C: it is attached to the first layer 1A of the base. The 4th is 1D, and it is on the layer 1B of the charm material. The plurality of raised fiber bodies 30 composed of fine fine fibers have been transmitted (10) and formed in the thickness direction of the cushioning material 1Q and connected to the base bodies 1B, 1C, and 1D. The scared layer U is shown in Fig. 2 In the cushioning material 10, the first affinity layer 1A, the first 1B, the third enchantment layer lc, and the fourth drum layer ❿ are classified into a eucalyptus layer or a para-type aromatic polyamine. - two rooms芳098123601 ^ 一' I both contain 13 201008774 Yes. For example, the 3rd enchantment layer 1C and the 4th enchantment layer 1D are made of short fibers with low thermal conductivity (here, meta-type aromatic polyamide) In this case, the heat unevenness of the hot plate 40 can be alleviated. The first consumable layer 1A and the second material layer 1B are short fibers having a high thermal conductivity (here, the para-type aromatic poly In this case, since the cushioning property is improved, the temperature-increasing speed adjustment and the cushioning property can be set uniformly in the entire cushioning material 1。. The second cushioning material 20 shown in Fig. 3 is configured as the second cushioning material. The surface layer 1 (here, one surface and the other surface) is laminated with the surface layer 1E. That is, the surface layer 1E is joined to the surface of the third felt layer 1C by the joining means p. The surface layer 1E is joined to the surface of the fourth felt layer 1D by the joining means p. The first cushioning material 20, the first felt layer ία, the second felt layer 1B, and the third felt layer 1C and f 4 The drum layer 1D contains one of m vertical aromatic polyamine or para-type aromatic polyamine, or both. In the material 10 and the second cushioning material 20, the base 10B is formed of a woven fabric formed by weaving a warp yarn composed of a heat-resistant fiber and a weft yarn. The heat-resistant fiber is derived from a meta-type aromatic polyamine, a pair. The group of aromatic aromatic polyamines, all-aromatic poly-g-fibers, poly-p-phenylene stupid (pB〇) fibers, and stainless steel fibers is selected from the group consisting of. The above-described weaving strength of the warp yarn 10B1 and the weft yarn 10B2 098123601 14 201008774 may be replaced with a structure in which only the warp yarn and the weft yarn are overlapped. In this case, the base 10B has the warp yarn 10B1 and the weft yarn 10B2, and most of the pile fiber body 30 penetrates the base material ι and is formed in the thickness direction of the cushioning material 1〇, 2〇. Therefore, the warp yarn 10B1 extending in the two directions, the weft banknote 10B2 extending in the X direction, and the raised fiber body 30 extending in the γ direction (the buffer material 10, 2〇 thickness direction) are substantially orthogonal to each other in a three-dimensional configuration ( That is, χ, γ, • z is the coordinate system). And because the pilling fiber body 3 〇 penetrates the substrate 1 〇 B, the intermediate portion of the pilling fiber 胄 30 is solidly held with the substrate i 〇 B (10) 2 to 4). As a result, since most of the raised fiber bodies 30 exert an elastic effect toward the thickness direction of the cushioning members 10, 20, the cushioning material W and other cushioning properties are improved. On the base 1〇B, the first surface layer u and the second layer are used on the surface (surface) and the other surface (back surface). In the first coffin layer, the surface is rolled and installed (4) 3G layer 1G. On the surface of the 2nd 1B, the needle-rolled shirt is covered with the fourth layer of money. ^ On the surface of the 0th layer of the first layer of wool 1C and the surface of the layer of the 4th layer of the layer of the felt layer ln, respectively, the town ΓΠΜϋ is placed, ΛΑ 呀σ means Ρ. The means of bonding are, for example, unrestricted (3) suffixes of 8 valences. Further, when the surface layer 1E is placed on the surface of the joint hand „, At, and the layer is in the state of the layer, the whole body is subjected to the entanglement of the ''alpha'' bonding means p, which melts.

Then, needle rolling is performed, and interlacing treatment of short fibers is performed on the woven fabric (base 10B). Thereby, the first number of material layers 1A and the second felt layer 1B are laminated on one surface (surface) and the other surface (back surface) of the woven fabric (base body 10B). In this needle rolling, a needle for needle rolling (hereinafter referred to as "needle") of 6 or less barbs (thorn) is used. The number of needle rolling is 5 times/cm2 or less. Further, the first barb of the knitting needle (the barb that is closest to the position viewed from the needle tip) is set at a position that comes into contact with the surface of the woven fabric, and the needle is applied. By this interlacing treatment, the axial direction of the short fibers is parallel to the woven fabric. (sequence 2)

Finally, if the second felt material u and the second felt material 1B have reached a predetermined basis weight, they are moved to the order of forming the raised fiber body 3〇. (Sequence 3) This sequence uses a needle having more than 098,123,601,08,080,000 barbs (thorns) than the needle used in the above-described interlacing process (for example, a needle having 8 barbs or more per 1 edge). Then, a plurality of raised fibrous bodies 30 are formed in the thickness direction of the cushioning members 10 and 20 by the knitting needles. For example, a needle with a double-edge 18 barb is used, and the number of times of needle rolling is set to 8 times/cm or more. The knitting needle is set as the last barb of the knitting needle (the inverted fishing at the farthest position viewed from the needle tip) is located in the weaving The status of the cloth position. The right needle is rolled in this state, and the plurality of raised fiber bodies 30 are passed through the woven fabric (Kilu body 10B)' formed in the thickness direction of the cushioning material 1〇, 2〇, and all the viewing materials are connected to each other. The cushioning members 10, 20 having a plurality of raised fibrous bodies 30 are completed. When the fineness of the short fibers of the field is less than 1 〇 dtex, the short fibers are easily pilling due to the needles, and it is difficult to form the raised fibrous body 30. On the other hand, when the fineness of the short fibers exceeds 6. Qdtex, the shortness between the short fibers is weak, so that it is difficult to form the densely-bricked fibrous body 3G, and the cushioning material (10) is weak. l O O O O O O O O O O O O O O O O O O O O O O O O O O O O O O O O O O O O O O O O O O O O. According to this, Ib., ^, because it is difficult to make short fibers into hair balls due to needle rolling, so it can be light 30. Further, since the interlacing between the short fibers becomes stronger, the foaming fiber body density is raised into the fiber body 30, and the cushioning materials 1G and (4) can be easily formed to be high. 3. The heat resistance of the Odtex is stronger. Further, in the 'invention of the present invention', a fine-density staple fiber is used. The cushioning materials 10 and 20 having the above-described configuration are suitable for use in a laminated plate forming and pressing device 1 such as the manufacturing device of the 098123601 201008774 double-sided printed wiring board shown in FIG. 1, which is a double-sided printed wiring as shown in FIG. The laminate of the substrate of the board belongs to the case of a laminated product. [Examples] Hereinafter, the heat-resistant cushioning material for press forming of the present invention will be described in more detail using examples. Further, the following examples are not intended to carry out any of the invention. In the examples and comparative examples, the following structures all use a common substance.

The short fiber of the para-type aromatic polyamine is a polystyrene terephthalamide (KEVLAR®, trade name/DuPont) 5dtex cut length 5 〇 coffee short fiber. ^ (Example 1) On the surface and the back surface of the woven fabric W, a cotton web formed of short fibers of polyphenylene terephthalate is laminated, and then needle drying is performed to form a felt layer 1A and a second felt material, respectively. In the layer 1B, the cushioning material of the example was obtained. (Example 2) A cotton web of short fibers of (10) was laminated on the surface and the back surface of the woven fabric. Then, needle rolling was performed to form the first return. The buffer material of Example 2 was obtained by layer u and the 098123601 19 201008774 2 felt layer IB.

Then, the cushioning material of Example 3 was prepared by performing "needle rolling" to form the first felt layer 1A and the second felt layer 1B'. (Example 4) On the surface of the woven fabric (one of which was hot On the surface of the disk 40, 50% by weight of short fibers of polyparaphenylene terephthalamide and 50% by weight of carbon fibers were mixed to form a net and laminated. On the back surface of the woven fabric (the surface on the back side of one of the hot plates 4), 50% by weight of the short fibers of CONEX® and 50% by weight of the carbon fibers were mixed to form a net and laminated.
