在如上所述成份中’可在不至於實質地損及液晶性範 -13- 200951256 圍內含有其他高分子，例如聚烯烴、聚醯胺、聚酯、聚芳酯 、聚碳酸酯、聚苯硫醚、聚酯醚酮等之具有纖維形成能之高 分子。 進一步也可含有各種添加劑，例如顏料、碳、熱穩定 劑、紫外線吸收劑、潤滑劑、螢光增白劑等。 由構成本發明之熔融異方向性芳香族聚酯所構成之纖 維係以一般的熔融紡絲法即可製得。假設高分子之熔點爲 MP ( °C )時，則以比通常MP爲高出1 0至50°C之溫度加以 紡絲。結絲後之纖維，由於並未具有足夠的性能，因此施加 熱處理。藉由熱處理則可發生固相聚合（有時候也伴隨部份 交聯反應）使得強度、彈性模數提高，並且使得熔點上升。 另外，在本發明所謂的「熔點（MP )」係藉由使用 Mettler-Toledo International Inc.製造之 TA-3000 DSC，並 在升溫速度爲20°C /分鐘之條件下所測定之吸熱波峰溫度。 熱處理係可在氮氣等之惰性大氣或如含氧空氣之活性 大氣中或在減壓下進行。熱處理大氣較佳爲露點（dew point )爲-40°C以下之氣體。較佳的溫度條件係可列舉由纖維之 熔點以下起逐漸地升溫之模式。處理時間可視目的之性能而 實施數秒鐘至數十小時。通常熱處理係在纖維之狀態下進行 ，但是視需要也可在梭織物或編織物之狀態下進行。 本發明之布帛係複絲紗狀之梭織-編織物，且該複絲紗 狀之纖度則必須爲20至3 00 dtex。若纖度爲小於20 dtex 時，則不容易進行爲獲得目的強度之高密度的梭織-編織製 造，且無法獲得剛性爲高者。在另一方面，若爲超過3 00 dtex -14- 200951256 時，則將不符合輕薄之本發明之目的，因此較佳爲25至250 dtex，更佳爲 30 至 230 dtex。 關於本發明之布帛，布帛之厚度D (單位：mm)與用 於構成布帛之複絲紗狀的換算直徑RD (單位：mm )之關係 也可爲D/RDS 1.2。若D/RD之比爲高時，則有無法發揮本 發明之重要目的之薄與剛性兩者並存的顧慮，因此較佳爲 D/RDS 1.1，更佳爲 0.4S D/RDS 1.0。 在此本發明所謂的「換算直徑RD (單位：mm )」係將 複絲紗狀視爲圓形截面之單絲（monofilament)時之直徑， 且可由下式計算得之値： RD= 0.01 13 ( T/ p ) 1/2 其中，T係用於構成布帛之複絲紗狀之纖度（單位：dtex ) ，；0係用於構成纖維的纖維之比重（單位：g/cc)。 RD係可根據纖維之纖度及比重適當地選擇，例如RD 爲約0.03至0.3，較佳爲約0.05至0.25。 此外，在本發明所謂的「布帛之厚度D (單位：mm) 」係藉由使用由東洋精機製作所（Toyoseiki Seisaku-Sho Ltd.)製造之數位式測定器B-2所測得之値，D係例如約0.01 至0.3，較佳爲約0.02至0.2。 並且，假設布帛之每單位面積之質量爲W(單位：g/m2 )、布帛之每單位面積之質量W (單位：g/m2)、厚度D (單位：mm)、及拉伸斷裂強度Sb (單位：N/cm)時，則 必須爲布帛之縱向方向及橫向方向爲皆可符合下式之條件 -15- 200951256In the above-mentioned ingredients, it can contain other polymers, such as polyolefins, polyamides, polyesters, polyarylates, polycarbonates, polyphenyls, without substantially impairing the liquid crystallinity-13-200951256. A polymer having a fiber forming ability such as thioether or polyester ether ketone. Further, various additives such as a pigment, carbon, a heat stabilizer, an ultraviolet absorber, a lubricant, a fluorescent whitening agent and the like may be contained. The fiber composed of the molten isotropic aromatic polyester constituting the present invention can be obtained by a general melt spinning method. Assuming that the melting point of the polymer is MP (°C), it is spun at a temperature of 10 to 50 ° C higher than that of normal MP. The fiber after the knot is heat treated because it does not have sufficient properties. By heat treatment, solid phase polymerization (sometimes accompanied by partial crosslinking reaction) occurs to increase the strength, modulus of elasticity, and increase the melting point. Further, the "melting point (MP)" in the present invention is an endothermic peak temperature measured by using a TA-3000 DSC manufactured by Mettler-Toledo International Inc. at a temperature rising rate of 20 ° C /min. The heat treatment can be carried out in an inert atmosphere such as nitrogen or in an active atmosphere such as oxygen-containing air or under reduced pressure. The heat-treated atmosphere is preferably a gas having a dew point of -40 ° C or less. The preferred temperature conditions are those in which the temperature is gradually increased from the melting point of the fiber. The processing time can be performed for a few seconds to several tens of hours depending on the performance of the destination. Usually, the heat treatment is carried out in the state of fibers, but it may be carried out in the state of a woven fabric or a woven fabric as needed. The fabric of the present invention is a multifilament yarn-like woven-knitted fabric, and the fineness of the multifilament yarn must be 20 to 300 dtex. When the fineness is less than 20 dtex, it is not easy to perform a high-density woven-weaving process for obtaining the target strength, and it is not possible to obtain a high rigidity. On the other hand, if it is more than 300 dtex -14 - 200951256, it will not meet the purpose of the thin invention, and therefore it is preferably 25 to 250 dtex, more preferably 30 to 230 dtex. Regarding the fabric of the present invention, the relationship between the thickness D (unit: mm) of the fabric and the converted diameter RD (unit: mm) for forming the multifilament yarn of the fabric may be D/RDS 1.2. When the ratio of D/RD is high, there is a concern that both thinness and rigidity which do not exhibit the important object of the present invention coexist, and therefore it is preferably D/RDS 1.1, more preferably 0.4S D/RDS 1.0. Here, the "converted diameter RD (unit: mm)" in the present invention is a diameter when a multifilament yarn is regarded as a monofilament of a circular cross section, and can be calculated by the following formula: RD = 0.01 13 ( T / p ) 1/2 where T is the fineness (unit: dtex) of the multifilament yarn constituting the fabric, and 0 is the specific gravity (unit: g/cc) of the fiber constituting the fiber. The RD system can be appropriately selected depending on the fineness and specific gravity of the fiber, for example, RD is from about 0.03 to 0.3, preferably from about 0.05 to 0.25. Further, the "thickness D of the fabric (unit: mm)" as used in the present invention is measured by using a digital type measuring device B-2 manufactured by Toyo Seiki Co., Ltd. (Toyoseiki Seisaku-Sho Ltd.), D For example, it is about 0.01 to 0.3, preferably about 0.02 to 0.2. Further, it is assumed that the mass per unit area of the fabric is W (unit: g/m2), the mass per unit area of the fabric W (unit: g/m2), the thickness D (unit: mm), and the tensile breaking strength Sb (Unit: N/cm), the longitudinal direction and the lateral direction of the fabric must be the conditions of the following formula -15- 200951256

Sb/W/D2 30。 若Sb/W/D爲小於30時，則無法獲得本發明之目的之 輕量且高強度之布帛，因此較佳爲Sb/W/D 2 40,更佳爲400 2 Sb/W/D2 50。 此外，W與拉伸斷裂強度Sb( N/cm )之關係係布帛之 縱向方向及橫向方向爲皆可符合下式之條件：Sb/W/D2 30. If the Sb/W/D is less than 30, the lightweight and high-strength fabric for the purpose of the present invention cannot be obtained, so it is preferably Sb/W/D 2 40, more preferably 400 2 Sb/W/D2 50. . In addition, the relationship between W and the tensile strength at break Sb (N/cm) is such that the longitudinal direction and the transverse direction of the fabric are both in accordance with the following formula:

Sb/W2 5。 若Sb/W爲太低時，則有無法獲得本發明之目的之輕量 且高強度之布帛的顧慮，因此較佳爲Sb/W2 7，更佳爲15 2 Sb/W g 9。該條件係不容易由一般的泛用纖維（例如由聚 酯或尼龍所構成之纖維）獲得。 並且，Sb與中間（斷裂伸度之1/2)伸長時之強度Sc (N/crn )之關係，布帛之縱向方向及橫向方向也爲皆可符 合下式之條件：Sb/W2 5. If Sb/W is too low, there is a concern that a lightweight and high-strength fabric which does not have the object of the present invention is obtained. Therefore, Sb/W2 7 is more preferable, and 15 2 Sb/W g 9 is more preferable. This condition is not easily obtained by a general general-purpose fiber such as a fiber composed of polyester or nylon.

Further, in the molten isotropic aromatic polyester fiber for constituting the fabric of the present invention, the long diameter and the short diameter of the fiber cross section are preferably long diameter/short diameter = 1.1 to 3.0. If the ratio of the long diameter to the short diameter is less than 1.1, there is a case where the flaking effect can not be obtained by -19-200951256. On the other hand, when the ratio of the long diameter to the short diameter is more than 3.0, there is a possibility that a sheet having a superior strength and elastic modulus which is the object of the present invention cannot be obtained due to breakage or breakage, and therefore it is preferable.

Further, by applying Examples 8 and 9 to the woven fabric of Example 2, the strength of the laminate can be further improved. On the other hand, in Comparative Example 1 in which the nonwoven fabric was used, the longitudinal direction and the lateral direction of the nonwoven fabric failed to satisfy the condition of Sb/W/D $30. Moreover, the laminate obtained by using the nonwoven fabric does not exhibit sufficient rigidity. Further, in Comparative Example 2 in which a plain weave fabric having a high multifilament fineness was used, the plain weave fabric also failed to meet the conditions of Sb/W/D 2 30, and was obtained by using the plain weave fabric. The laminate also does not have sufficient rigidity. Also, in Comparative Example 3 using a plain weave fabric formed of glass fibers, the plain weave fabric did not conform to the conditions of Sb/W/D 2 30, and the laminate obtained by using the plain weave fabric was Although it has superior rigidity, the weight of the laminate is so high that weight reduction cannot be achieved. Further, the dielectric constant of Comparative Example 3 was also high. © [Industrial Applicability] The sheet material of the present invention can be used for substrates for printed boards, prepreg applications, high-strength films, and various building materials, and can be applied by heat compression.
